periods of time.

. When road and weatherconditions are appropriate, usecruise control.

. Always follow posted speed limitsor drive more slowly whenconditions require.

. Keep vehicle tires properlyinflated.

. Combine several trips into asingle trip.

. Replace the vehicle's tires with thesame TPC Spec number moldedinto the tire's sidewall nearthe size.

. Follow recommended scheduledmaintenance.

Driving for Better EnergyEfficiency (PLUG-IN Only)Use the following tips to helpmaximize energy efficiency and range.

In colder temperatures, while theseefficiency tips will help, the electricvehicle driving range may be lowerdue to higher energy usage.

Driving Style

Acceleration/Braking/Coasting

Avoid unnecessary rapid accelerationsand decelerations.

Electric range is maximized at80 km/h (50 mph) and below. Higherspeeds use more energy and cansignificantly reduce electric range.

Use cruise control when appropriate.

Plan ahead for decelerations and coastwhenever possible. For example, donot rush to traffic signals.

Do not shift to N (Neutral) to coast.The vehicle recovers energy whilecoasting and braking in D (Drive) or M(Manual Mode).

Drive Mode and PRNDM Selection

Use Tour Mode when possible.

Sport Mode provides more responsiveacceleration than Tour Mode but canreduce efficiency.

Use Hold Mode on a trip where it isexpected that all of the electric chargewill be depleted. Use Hold Modemainly during highway or high speeddriving to maximize both EV milesand fuel efficiency.

Use M (Manual Model) in heavystop-and-go traffic or when travelingdownhill. M (Manual Mode) requiresless brake pedal application andprovides a controlled, efficient way toslow the vehicle down.

Climate Setting

Using the heat and air conditioningsystems decreases the energy availablefor electric driving.

Optimal energy efficiency is achievedwith the heat, air conditioning, andfan turned off.

Less energy is used at low fan speeds.

Use the heated seat feature and theheated steering wheel instead ofclimate settings. Heating the seat andsteering wheel uses less energy thanheating the vehicle interior.

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) -2018 - CRC - 3/1/18

IN BRIEF 33

Use remote start to heat or cool theinterior when the vehicle is plugged into maximize the electric range byutilizing electricity from the electricaloutlet.

In hot weather, avoid parking in directsunlight or use sunshades inside thevehicle.

Turn off the front and rear windowdefog/defrost when they are no longerneeded.

Avoid driving with the windows openat highway speeds.

Vehicle Charging/Maintenance

Charging

Keep the vehicle plugged in, evenwhen fully charged, to keep thebattery temperature ready for the nextdrive. This is important when outsidetemperatures are extremely hotor cold.

Maintenance

Always keep the tires properly inflatedand the vehicle properly aligned.

The weight of excess cargo in thevehicle affects efficiency and range.Avoid carrying more than is needed.

If fuel is not regularly used, considerkeeping the fuel tank only one-thirdfull. Excess fuel weight impactsefficiency and range.

For fuel recommendations, see Fuel0 305.

Avoid unnecessary use of electricalaccessories. Power used for functionsother than propelling the vehicle willreduce EV range.

Using a rooftop carrier will reduceefficiency due to additional weightand drag.

Always wear a seat belt, and checkthat all passenger(s) are restrainedproperly too.

This vehicle has indicators as areminder to buckle the seat belts. SeeSeat Belt Reminders 0 141.

Why Seat Belts Work

When riding in a vehicle, you travel asfast as the vehicle does. If the vehiclestops suddenly, you keep going untilsomething stops you. It could be thewindshield, the instrument panel,or the seat belts!

When you wear a seat belt, you andthe vehicle slow down together. Thereis more time to stop because you stopover a longer distance and, when wornproperly, your strongest bones takethe forces from the seat belts. That iswhy wearing seat belts makes suchgood sense.

Questions and Answers AboutSeat Belts

Q: Will I be trapped in the vehicleafter a crash if I am wearing aseat belt?

A: You could be— whether you arewearing a seat belt or not. Yourchance of being conscious duringand after a crash, so you canunbuckle and get out, is muchgreater if you are belted.

Q: If my vehicle has airbags, whyshould I have to wear seat belts?

A: Airbags are supplemental systemsonly. They work with seat belts—not instead of them. Whether ornot an airbag is provided, alloccupants still have to buckle upto get the most protection.

Also, in nearly all states and in allCanadian provinces, the lawrequires wearing seat belts.

How to Wear Seat BeltsProperlyThis section is only for people ofadult size.

There are special things to knowabout seat belts and children, andthere are different rules for smallerchildren and infants. If a child will beriding in the vehicle, see Older Children0 98 or Infants and Young Children0 99. Follow those rules for everyone'sprotection.

It is very important for all occupantsto buckle up. Statistics show thatunbelted people are hurt more oftenin crashes than those who are wearingseat belts.

There are important things to knowabout wearing a seat belt properly.

. Sit up straight and always keepyour feet on the floor in frontof you.

. Always use the correct buckle foryour seating position.

. Wear the lap part of the belt lowand snug on the hips, justtouching the thighs. In a crash,

this applies force to the strongpelvic bones and you would beless likely to slide under the lapbelt. If you slid under it, the beltwould apply force on yourabdomen. This could cause seriousor even fatal injuries.

. Wear the shoulder belt over theshoulder and across the chest.These parts of the body are bestable to take belt restraining forces.The shoulder belt locks if there isa sudden stop or crash.

{ Warning

You can be seriously injured,or even killed, by not wearing yourseat belt properly.

. Never allow the lap orshoulder belt to become looseor twisted.

. Never wear the shoulder beltunder both arms or behindyour back.

. Never route the lap orshoulder belt over an armrest.

Lap-Shoulder BeltAll seating positions in the vehiclehave a lap-shoulder belt.

The following instructions explainhow to wear a lap-shoulder beltproperly.

1. Adjust the seat, if the seat isadjustable, so you can sit upstraight. To see how, see “Seats”in the Index.

2. Pick up the latch plate and pullthe belt across you. Do not let itget twisted.

The lap-shoulder belt may lock ifyou pull the belt across you veryquickly. If this happens, let thebelt go back slightly to unlock it.Then pull the belt across youmore slowly.

If the shoulder portion of apassenger belt is pulled out allthe way, the child restraintlocking feature may be engaged.If this happens, let the belt goback all the way and start again.

Engaging the child restraintlocking feature in the frontoutboard seating position mayaffect the passenger sensingsystem. See Passenger SensingSystem 0 92.

If the webbing locks in the latchplate before it reaches thebuckle, tilt the latch plate flat tounlock.

3. Push the latch plate into thebuckle until it clicks.

Pull up on the latch plate tomake sure it is secure. If the beltis not long enough, see Seat BeltExtender 0 84.

Position the release button onthe buckle so that the seat beltcould be quickly unbuckled ifnecessary.

4. If equipped with a shoulder beltheight adjuster, move it to theheight that is right for you. See“Shoulder Belt Height Adjuster”later in this section forinstructions on use andimportant safety information.

5. To make the lap part tight, pullup on the shoulder belt.

To unlatch the belt, push the buttonon the buckle. The belt should returnto its stowed position.

Always stow the seat belt slowly. If theseat belt webbing returns quickly tothe stowed position, the retractor maylock and cannot be pulled out. If thishappens, pull the seat belt straight outfirmly to unlock the webbing, andthen release it. If the webbing is stilllocked in the retractor, see yourdealer.

Before a door is closed, be sure theseat belt is out of the way. If a door isslammed against a seat belt, damagecan occur to both the seat belt andthe vehicle.

Shoulder Belt Height Adjuster

The vehicle has a shoulder belt heightadjuster for the driver and frontoutboard passenger seating positions.

Adjust the height so the shoulderportion of the belt is on the shoulderand not falling off of it. The beltshould be close to, but not contacting,the neck. Improper shoulder beltheight adjustment could reduce the

Automatic Seat Belt TighteningSystem

The vehicle may have the AutomaticSeat Belt Tightening System.

The system activates duringemergency braking and/or suddendriving maneuvers and releases whendriving conditions return to normal.

The system will not activate if theTraction Control/Electronic StabilityControl system is not functioningproperly. See Traction Control/Electronic Stability Control 0 242.If there is a problem with theAutomatic Seat Belt TighteningSystem, a message displays on theDriver Information Center (DIC). If asystem unavailable message displaysrepeatedly or a service messagedisplays, see your dealer. Other seatbelt functions are not affected by theAutomatic Seat Belt TighteningSystem.

Seat Belt Pretensioners

This vehicle has seat beltpretensioners for front outboardoccupants. Although the seat beltpretensioners cannot be seen, they arepart of the seat belt assembly. Theycan help tighten the seat belts duringthe early stages of a moderate tosevere frontal, near frontal, or rear

crash if the threshold conditions forpretensioner activation are met. Seatbelt pretensioners can also helptighten the seat belts in a side crashor a rollover event.

Pretensioners work only once. If thepretensioners activate in a crash, thepretensioners and probably otherparts of the vehicle's seat belt systemwill need to be replaced. See ReplacingSeat Belt System Parts after a Crash0 85.

Do not sit on the outboard seat beltwhile entering or exiting the vehicle orat any time while sitting in the seat.Sitting on the seat belt can damagethe webbing and hardware.

Rear Seat Belt Comfort Guides

Rear seat belt comfort guides mayprovide added seat belt comfort forolder children who have outgrownbooster seats and for some adults.When installed on a shoulder belt, thecomfort guide positions the belt awayfrom the neck and head.

Comfort guides are available throughyour dealer for the rear outboardseating positions. Instructions areincluded with the guide.

Seat Belt Use DuringPregnancySeat belts work for everyone,including pregnant women. Like alloccupants, they are more likely to beseriously injured if they do not wearseat belts.

A pregnant woman should wear alap-shoulder belt, and the lap portionshould be worn as low as possible,below the rounding, throughout thepregnancy.

The best way to protect the fetus is toprotect the mother. When a seat beltis worn properly, it is more likely thatthe fetus will not be hurt in a crash.For pregnant women, as for anyone,the key to making seat belts effectiveis wearing them properly.

Seat Belt ExtenderIf the vehicle's seat belt will fastenaround you, you should use it.

But if a seat belt is not long enough,your dealer will order you an extender.When you go in to order it, take theheaviest coat you will wear, so theextender will be long enough for you.To help avoid personal injury, do notlet someone else use it, and use itonly for the seat it is made to fit. Theextender has been designed for adults.Never use it for securing childrestraints. For more information on

the proper use and fit of seat beltextenders see the instruction sheetthat comes with the extender.

Safety System CheckPeriodically check the seat beltreminder, seat belts, buckles, latchplates, retractors, shoulder belt heightadjusters (if equipped), and seat beltanchorages to make sure they are allin working order. Look for any otherloose or damaged seat belt systemparts that might keep a seat beltsystem from performing properly. Seeyour dealer to have it repaired. Tornor frayed seat belts may not protectyou in a crash. They can rip apartunder impact forces. If a belt is tornor frayed, have it replacedimmediately.

Make sure the seat belt reminder lightis working. See Seat Belt Reminders0 141.

Keep seat belts clean and dry. See SeatBelt Care 0 85.

Airbag SystemThe vehicle has the following airbags:

. A frontal airbag for the driver

. A frontal airbag for the frontoutboard passenger

. A knee airbag for the driver

. A knee airbag for the frontoutboard passenger

. A seat-mounted side impact airbagfor the driver

. A seat-mounted side impact airbagfor the front outboard passenger

. A roof-rail airbag for the driverand the passenger seated directlybehind the driver

. A roof-rail airbag for the frontoutboard passenger and thepassenger seated directly behindthe front outboard passenger

All vehicle airbags have the wordAIRBAG on the trim or on a label nearthe deployment opening.

For frontal airbags, the word AIRBAGis on the center of the steering wheelfor the driver and on the instrumentpanel for the front outboardpassenger.

For knee airbags, the word AIRBAG ison the lower part of the instrumentpanel.

For seat-mounted side impact airbags,the word AIRBAG is on the side of theseatback closest to the door.

For roof-rail airbags, the word AIRBAGis on the ceiling or trim.

Airbags are designed to supplementthe protection provided by seat belts.Even though today's airbags are alsodesigned to help reduce the risk ofinjury from the force of an inflatingbag, all airbags must inflate veryquickly to do their job.

Here are the most important things toknow about the airbag system:

{ Warning

You can be severely injured orkilled in a crash if you are notwearing your seat belt, even withairbags. Airbags are designed towork with seat belts, not replacethem. Also, airbags are not designedto inflate in every crash. In somecrashes seat belts are the onlyrestraint. See When Should anAirbag Inflate? 0 89.

Wearing your seat belt during acrash helps reduce your chance ofhitting things inside the vehicle orbeing ejected from it. Airbags are“supplemental restraints” to theseat belts. Everyone in the vehicleshould wear a seat belt properly,whether or not there is an airbagfor that person.

{ Warning

Because airbags inflate with greatforce and faster than the blink of aneye, anyone who is up against,or very close to, any airbag when itinflates can be seriously injured orkilled. Do not sit unnecessarilyclose to any airbag, as you would beif sitting on the edge of the seat orleaning forward. Seat belts helpkeep you in position before andduring a crash. Always wear a seatbelt, even with airbags. The drivershould sit as far back as possiblewhile still maintaining control ofthe vehicle. The seat belts and thefront outboard passenger airbagsare most effective when you aresitting well back and upright in theseat with both feet on the floor.

Occupants should not lean on orsleep against the door or sidewindows in seating positions withseat-mounted side impact airbagsand/or roof-rail airbags.

{ Warning

Children who are up against,or very close to, any airbag when itinflates can be seriously injured orkilled. Always secure childrenproperly in the vehicle. To readhow, see Older Children 0 98 orInfants and Young Children 0 99.

There is an airbag readiness light onthe instrument cluster, which showsthe airbag symbol. The system checksthe airbag electrical system formalfunctions. The light tells you ifthere is an electrical problem. SeeAirbag Readiness Light 0 142.

Do not use seat accessories thatblock the inflation path of aseat-mounted side impact airbag.

Never secure anything to the roof ofa vehicle with roof-rail airbags byrouting a rope or tie‐down throughany door or window opening. If youdo, the path of an inflating roof-railairbag will be blocked.

When Should an AirbagInflate?This vehicle is equipped with airbags.See Airbag System 0 86. Airbags aredesigned to inflate if the impactexceeds the specific airbag system'sdeployment threshold. Deploymentthresholds are used to predict how

severe a crash is likely to be in timefor the airbags to inflate and helprestrain the occupants. The vehiclehas electronic sensors that help theairbag system determine the severityof the impact. Deployment thresholdscan vary with specific vehicle design.

Frontal airbags are designed to inflatein moderate to severe frontal or nearfrontal crashes to help reduce thepotential for severe injuries, mainly tothe driver's or front outboardpassenger's head and chest.

Whether the frontal airbags will orshould inflate is not based primarilyon how fast the vehicle is traveling.It depends on what is hit, thedirection of the impact, and howquickly the vehicle slows down.

Frontal airbags may inflate atdifferent crash speeds depending onwhether the vehicle hits an objectstraight on or at an angle, andwhether the object is fixed or moving,rigid or deformable, narrow or wide.

Frontal airbags are not intended toinflate during vehicle rollovers, in rearimpacts, or in many side impacts.

In addition, the vehicle has advancedtechnology frontal airbags. Advancedtechnology frontal airbags adjust therestraint according to either crashseverity or occupant interaction.

Knee airbags are designed to inflate inmoderate to severe frontal or nearfrontal impacts. Knee airbags are notdesigned to inflate during vehiclerollovers, in rear impacts, or in manyside impacts.

Seat-mounted side impact airbags aredesigned to inflate in moderate tosevere side crashes depending on thelocation of the impact. Seat-mountedside impact airbags are not designedto inflate in frontal impacts, nearfrontal impacts, rollovers, or rearimpacts. A seat-mounted side impactairbag is designed to inflate on theside of the vehicle that is struck.

Roof-rail airbags are designed toinflate in moderate to severe sidecrashes depending on the location ofthe impact. In addition, these roof-railairbags are designed to inflate duringa rollover or in a severe frontalimpact. Roof-rail airbags are notdesigned to inflate in rear impacts.

90 SEATS AND RESTRAINTS

Both roof-rail airbags will inflate wheneither side of the vehicle is struck,if the sensing system predicts that thevehicle is about to roll over on itsside, or in a severe frontal impact.

In any particular crash, no one cansay whether an airbag should haveinflated simply because of the vehicledamage or repair costs.

What Makes an AirbagInflate?In a deployment event, the sensingsystem sends an electrical signaltriggering a release of gas from theinflator. Gas from the inflator fills theairbag causing the bag to break out ofthe cover. The inflator, the airbag, andrelated hardware are all part of theairbag module.

For airbag locations, see Where Are theAirbags? 0 87.

How Does an AirbagRestrain?In moderate to severe frontal or nearfrontal collisions, even beltedoccupants can contact the steeringwheel or the instrument panel. Inmoderate to severe side collisions,even belted occupants can contact theinside of the vehicle.

Airbags supplement the protectionprovided by seat belts by distributingthe force of the impact more evenlyover the occupant's body.

Rollover capable roof-rail airbags aredesigned to help contain the head andchest of occupants in the outboardseating positions in the first andsecond rows. The rollover capableroof-rail airbags are designed to helpreduce the risk of full or partialejection in rollover events, althoughno system can prevent all suchejections.

But airbags would not help in manytypes of collisions, primarily becausethe occupant's motion is not towardthose airbags. See When Should anAirbag Inflate? 0 89.

Airbags should never be regarded asanything more than a supplement toseat belts.

What Will You See after anAirbag Inflates?After frontal, knee, and seat-mountedside impact airbags inflate, theyquickly deflate, so quickly that somepeople may not even realize theairbags inflated. Roof-rail airbags maystill be at least partially inflated forsome time after they inflate. Somecomponents of the airbag module maybe hot for several minutes. Forlocation of the airbags, see Where Arethe Airbags? 0 87.

The parts of the airbag that come intocontact with you may be warm, butnot too hot to touch. There may besome smoke and dust coming fromthe vents in the deflated airbags.Airbag inflation does not prevent thedriver from seeing out of thewindshield or being able to steer thevehicle, nor does it prevent peoplefrom leaving the vehicle.

{ Warning

When an airbag inflates, there maybe dust in the air. This dust couldcause breathing problems forpeople with a history of asthma orother breathing trouble. To avoidthis, everyone in the vehicle shouldget out as soon as it is safe to doso. If you have breathing problemsbut cannot get out of the vehicleafter an airbag inflates, then getfresh air by opening a window or adoor. If you experience breathingproblems following an airbagdeployment, you should seekmedical attention.

The vehicle has a feature that mayautomatically unlock the doors, turnon the interior lamps and hazardwarning flashers, and shut off the fuelsystem after the airbags inflate. Thefeature may also activate, withoutairbag inflation, after an event thatexceeds a predetermined threshold.After turning the ignition off and thenon again, the fuel system will return

to normal operation; the doors can belocked, the interior lamps can beturned off, and the hazard warningflashers can be turned off using thecontrols for those features. If any ofthese systems are damaged in thecrash they may not operate as normal.

{ Warning

A crash severe enough to inflate theairbags may have also damagedimportant functions in the vehicle,such as the fuel system, brake andsteering systems, etc. Even if thevehicle appears to be drivable aftera moderate crash, there may beconcealed damage that could makeit difficult to safely operate thevehicle.

Use caution if you should attemptto restart the engine after a crashhas occurred.

PLUG-IN vehicles have a high voltagebattery and a standard 12-volt battery.If an airbag inflates or the vehicle hasbeen in a crash, the sensing system

may shut down the high voltagesystem. When this occurs, the highvoltage battery is disconnected andthe vehicle will not start. Before thevehicle can be operated again, it mustbe serviced at your dealer.

In many crashes severe enough toinflate the airbag, windshields arebroken by vehicle deformation.Additional windshield breakage mayalso occur from the front outboardpassenger airbag.

. Airbags are designed to inflateonly once. After an airbag inflates,you will need some new parts forthe airbag system. If you do notget them, the airbag system willnot be there to help protect you inanother crash. A new system willinclude airbag modules andpossibly other parts. The servicemanual for the vehicle covers theneed to replace other parts.

Even if the passenger sensingsystem has turned off the frontoutboard passenger airbag(s), nosystem is fail-safe. No one canguarantee that an airbag will notdeploy under some unusualcircumstance, even though theairbag(s) are off.

Never put a rear-facing childrestraint in the front seat, even ifthe airbag is off. If securing aforward-facing child restraint in thefront outboard passenger seat,always move the seat as far back asit will go. It is better to secure childrestraints in the rear seat. Considerusing another vehicle to transportthe child when a rear seat is notavailable.

The passenger sensing system isdesigned to turn off the frontoutboard passenger frontal airbag andknee airbag if:

. The front outboard passenger seatis unoccupied.

. The system determines that aninfant is present in a childrestraint.

. A front outboard passenger takeshis/her weight off of the seat for aperiod of time.

. There is a critical problem withthe airbag system or the passengersensing system.

When the passenger sensing systemhas turned off the front outboardpassenger frontal airbag and kneeairbag, the off indicator will light andstay lit as a reminder that the airbagsare off. See Passenger Airbag StatusIndicator 0 142.

The passenger sensing system isdesigned to turn on the frontoutboard passenger frontal airbag andknee airbag anytime the systemsenses that a person of adult size is

sitting properly in the front outboardpassenger seat. When the passengersensing system has allowed theairbag(s) to be enabled, the onindicator will light and stay lit as areminder that the airbag(s) are active.

For some children, including childrenin child restraints, and for very smalladults, the passenger sensing systemmay or may not turn off the frontoutboard passenger frontal airbag andknee airbag, depending upon theperson’s seating posture and bodybuild. Everyone in the vehicle who hasoutgrown child restraints should weara seat belt properly — whether or notthere is an airbag for that person.

The passenger sensing system isdesigned to turn off the frontoutboard passenger frontal airbag andknee airbag if the system determinesthat an infant is present in a childrestraint. If a child restraint has beeninstalled and the on indicator is lit:

1. Turn the vehicle off.

2. Remove the child restraint fromthe vehicle.

3. Remove any additional itemsfrom the seat such as blankets,cushions, seat covers, seatheaters, or seat massagers.

4. Reinstall the child restraintfollowing the directions providedby the child restraint

manufacturer and refer toSecuring Child Restraints (With theSeat Belt in the Rear Seat) 0 111or Securing Child Restraints (Withthe Seat Belt in the Front Seat)0 113.

Make sure the seat belt retractoris locked by pulling the shoulderbelt all the way out of theretractor when installing thechild restraint, even if the childrestraint is equipped with a seatbelt lock-off. When the retractorlock is set, the belt can betightened but not pulled out ofthe retractor.

5. If, after reinstalling the childrestraint and restarting thevehicle, the on indicator is stilllit, turn the vehicle off. Thenslightly recline the vehicleseatback and adjust the seatcushion, if adjustable, to makesure that the vehicle seatback isnot pushing the child restraintinto the seat cushion.

Also make sure the childrestraint is not trapped under thevehicle head restraint. If this

happens, adjust the headrestraint. See Head Restraints0 66.

6. Restart the vehicle.

The passenger sensing system may ormay not turn off the airbags for achild in a child restraint dependingupon the child’s size. It is better tosecure the child restraint in a rearseat. Never put a rear-facing childrestraint in the front seat, even if theon indicator is not lit.

If a person of adult size is sitting inthe front outboard passenger seat, butthe off indicator is lit, it could bebecause that person is not sittingproperly in the seat or that the childrestraint locking feature is engaged.Use the following steps to allow thesystem to detect that person andenable the front outboard passengerfrontal airbag and knee airbag:

1. Turn the vehicle off.

2. Remove any additional materialfrom the seat, such as blankets,cushions, seat covers, seatheaters, or seat massagers.

3. Place the seatback in the fullyupright position.

4. Have the person sit upright inthe seat, centered on the seatcushion, with legs comfortablyextended.

5. If the shoulder portion of thebelt is pulled out all the way, thechild restraint locking featurewill be engaged. This mayunintentionally cause thepassenger sensing system to turnthe airbag off for some

adult-sized occupants. If thishappens, unbuckle the belt, letthe belt go back all the way, andthen buckle the belt againwithout pulling the belt out allthe way.

6. Restart the vehicle and have theperson remain in this positionfor two to three minutes afterthe on indicator is lit.

{ Warning

If the front outboard passengerairbag is turned off for anadult-sized occupant, the airbag willnot be able to inflate and helpprotect that person in a crash,resulting in an increased risk ofserious injury or even death. Anadult-sized occupant should notride in the front outboard passengerseat, if the passenger airbag offindicator is lit.

Additional Factors AffectingSystem Operation

Seat belts help keep the passenger inposition on the seat during vehiclemaneuvers and braking, which helpsthe passenger sensing systemmaintain the passenger airbag status.See “Seat Belts” and “Child Restraints”in the Index for additionalinformation about the importance ofproper restraint use.

A thick layer of additional material,such as a blanket or cushion,or aftermarket equipment such as seatcovers, seat heaters, and seatmassagers can affect how well thepassenger sensing system operates.We recommend that you not use seatcovers or other aftermarket equipmentexcept when approved by GM for yourspecific vehicle. See Adding Equipmentto the Airbag-Equipped Vehicle 0 96 formore information about modificationsthat can affect how the systemoperates.

Child Restraints

Older Children

Older children who have outgrownbooster seats should wear the vehicle’sseat belts.

The manufacturer instructions thatcome with the booster seat state theweight and height limitations for thatbooster. Use a booster seat with alap-shoulder belt until the childpasses the fit test below:

. Sit all the way back on the seat.Do the knees bend at the seatedge? If yes, continue. If no, returnto the booster seat.

. Buckle the lap-shoulder belt. Doesthe shoulder belt rest on theshoulder? If yes, continue. If no,try using the rear seat beltcomfort guide, if available. See“Rear Seat Belt Comfort Guides”under Lap-Shoulder Belt 0 81. If acomfort guide is not available, or ifthe shoulder belt still does not reston the shoulder, then return to thebooster seat.

. Does the lap belt fit low and snugon the hips, touching the thighs?If yes, continue. If no, return tothe booster seat.

. Can proper seat belt fit bemaintained for the length of thetrip? If yes, continue. If no, returnto the booster seat.

Q: What is the proper way to wearseat belts?

A: An older child should wear alap-shoulder belt and get theadditional restraint a shoulder belt

can provide. The shoulder beltshould not cross the face or neck.The lap belt should fit snuglybelow the hips, just touching thetop of the thighs. This applies beltforce to the child's pelvic bones ina crash. It should never be wornover the abdomen, which couldcause severe or even fatal internalinjuries in a crash.

Also see “Rear Seat Belt ComfortGuides” under Lap-Shoulder Belt 0 81.

According to accident statistics,children are safer when properlyrestrained in a rear seating position.

In a crash, children who are notbuckled up can strike other peoplewho are buckled up, or can be thrownout of the vehicle. Older children needto use seat belts properly.

For example, in a crash at only40 km/h (25 mph), a 5.5 kg (12 lb)infant will suddenly become a110 kg (240 lb) force on a person'sarms. An infant or child should besecured in an appropriate restraint.

{ Warning

Children who are up against,or very close to, any airbag when itinflates can be seriously injured orkilled. Never put a rear-facing childrestraint in the front outboard seat.Secure a rear-facing child restraintin a rear seat. It is also better tosecure a forward-facing childrestraint in a rear seat.

SEATS AND RESTRAINTS 101

Child restraints are devices used torestrain, seat, or position children inthe vehicle and are sometimes calledchild seats or car seats.

There are three basic types of childrestraints:

. Forward-facing child restraints

. Rearward-facing child restraints

. Belt-positioning booster seats

The proper child restraint for yourchild depends on their size, weight,and age, and also on whether thechild restraint is compatible with thevehicle in which it will be used.

For each type of child restraint, thereare many different models available.When purchasing a child restraint, besure it is designed to be used in amotor vehicle. If it is, the restraint willhave a label saying that it meetsfederal motor vehicle safety standards.The restraint manufacturer'sinstructions that come with therestraint state the weight and heightlimitations for a particular childrestraint. In addition, there are manykinds of restraints available forchildren with special needs.

{ Warning

To reduce the risk of neck and headinjury in a crash, infants andtoddlers should be secured in arear-facing child restraint until agetwo, or until they reach themaximum height and weight limitsof their child restraint.

{ Warning

A young child's hip bones are stillso small that the vehicle's regularseat belt may not remain low onthe hip bones, as it should. Instead,it may settle up around the child'sabdomen. In a crash, the belt wouldapply force on a body area that isunprotected by any bony structure.This alone could cause serious orfatal injuries. To reduce the risk ofserious or fatal injuries during acrash, young children should alwaysbe secured in appropriate childrestraints.

Child Restraint Systems

Rear-Facing Infant Restraint

A rear-facing child restraint providesrestraint with the seating surfaceagainst the back of the infant.

The harness system holds the infantin place and, in a crash, acts to keepthe infant positioned in the restraint.

Forward-Facing Child Restraint

A forward-facing child restraintprovides restraint for the child's bodywith the harness.

Booster Seats

A belt-positioning booster seat is usedfor children who have outgrown theirforward-facing child restraint.Boosters are designed to improve thefit of the vehicle's seat belt systemuntil the child is large enough for thevehicle seat belts to fit properlywithout a booster seat.

Securing an Add-On ChildRestraint in the Vehicle

{ Warning

A child can be seriously injured orkilled in a crash if the childrestraint is not properly secured inthe vehicle. Secure the childrestraint properly in the vehicleusing the vehicle’s seat belt orLATCH system, following theinstructions that came with thatchild restraint and the instructionsin this manual.

To help reduce the chance of injury,the child restraint must be secured inthe vehicle. Child restraints must besecured in vehicle seats by lap belts orthe lap belt portion of a lap-shoulderbelt, or by the LATCH system. SeeLower Anchors and Tethers for Children(LATCH System) 0 104 for moreinformation. Children can beendangered in a crash if the childrestraint is not properly secured in thevehicle.

When securing an add-on childrestraint, refer to the instructions thatcome with the restraint which may beon the restraint itself or in a booklet,or both, and to this manual. The childrestraint instructions are important,so if they are not available, obtain areplacement copy from themanufacturer.

Keep in mind that an unsecured childrestraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraint inthe vehicle— even when no child isin it.

In some areas of the United Statesand Canada, Certified Child PassengerSafety Technicians (CPSTs) areavailable to inspect and demonstratehow to correctly use and install childrestraints. In the U.S., refer to theNational Highway Traffic SafetyAdministration (NHTSA) website tolocate the nearest child safety seatinspection station. For CPSTavailability in Canada, check withTransport Canada or the ProvincialMinistry of Transportation office.

Securing the Child Within theChild Restraint

{ Warning

A child can be seriously injured orkilled in a crash if the child is notproperly secured in the childrestraint. Secure the child properlyfollowing the instructions thatcame with that child restraint.

Where to Put the RestraintAccording to accident statistics,children and infants are safer whenproperly restrained in an appropriatechild restraint secured in a rearseating position.

Whenever possible, children aged12 and under should be secured in arear seating position.

Never put a rear-facing child restraintin the front. This is because the riskto the rear-facing child is so great ifthe airbag deploys.

A child in a rear-facing childrestraint can be seriously injured orkilled if the front passenger airbaginflates. This is because the back ofthe rear-facing child restraint wouldbe very close to the inflating airbag.A child in a forward-facing childrestraint can be seriously injured orkilled if the front passenger airbaginflates and the passenger seat is ina forward position.

Even if the passenger sensingsystem has turned off the frontpassenger frontal airbag, no systemis fail-safe. No one can guaranteethat an airbag will not deploy undersome unusual circumstance, eventhough it is turned off.

seat as far back as it will go. It isbetter to secure the child restraintin a rear seat.

See Passenger Sensing System 0 92for additional information.

When securing a child restraint withthe seat belts in a rear seat position,study the instructions that came withthe child restraint to make sure it iscompatible with this vehicle.

Child restraints and booster seats varyconsiderably in size, and some may fitin certain seating positions betterthan others.

Depending on where you place thechild restraint and the size of thechild restraint, you may not be able toaccess adjacent seat belts or LATCHanchors for additional passengers orchild restraints. Adjacent seatingpositions should not be used if thechild restraint prevents access to orinterferes with the routing of theseat belt.

Wherever a child restraint is installed,be sure to follow the instructions thatcame with the child restraint systemand secure the child restraint systemproperly.

Keep in mind that an unsecured childrestraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraint inthe vehicle — even when no child isin it.

rear-facing and forward-facing childseats can be properly installed usingeither the LATCH anchors or thevehicle’s seat belts. Do not use boththe seat belts and the LATCHanchorage system to secure arear-facing or forward-facingchild seat.

Booster seats use the vehicle’s seatbelts to secure the child in the boosterseat. If the manufacturer recommendsthat the booster seat be secured withthe LATCH system, this can be doneas long as the booster seat can bepositioned properly and there is nointerference with the properpositioning of the lap-shoulder belt onthe child.

Make sure to follow the instructionsthat came with the child restraint, andalso the instructions in this manual.

When installing a child restraint witha top tether, you must also use eitherthe lower anchors or the seat belts toproperly secure the child restraint.A child restraint must never beinstalled using only the top tether andanchor.

The LATCH anchorage system can beused until the combined weight of thechild plus the child restraint is29.5 kg (65 lbs). Use the seat belt aloneinstead of the LATCH anchoragesystem once the combined weight ismore than 29.5 kg (65 lbs).

See Securing Child Restraints (With theSeat Belt in the Rear Seat) 0 111 orSecuring Child Restraints (With the SeatBelt in the Front Seat) 0 113.

Child restraints built after March 2014will be labeled with the specific childweight up to which the LATCH systemcan be used to install the restraint.

The following explains how to attacha child restraint with theseattachments in the vehicle.

Not all vehicle seating positions orchild restraints have lower anchorsand attachments or top tether anchorsand attachments. In this case, the seatbelt must be used (with top tetherwhere available) to secure the childrestraint.

Securing Child Restraints(With the Seat Belt in theRear Seat)When securing a child restraint withthe seat belts in a rear seat position,study the instructions that came withthe child restraint to make sure it iscompatible with this vehicle.

If the child restraint has the LATCHsystem, see Lower Anchors and Tethersfor Children (LATCH System) 0 104 forhow and where to install the childrestraint using LATCH. If a childrestraint is secured in the vehicleusing a seat belt and it uses a toptether, see Lower Anchors and Tethersfor Children (LATCH System) 0 104 fortop tether anchor locations.

Do not secure a child seat in aposition without a top tether anchor ifa national or local law requires thatthe top tether be anchored, or if theinstructions that come with the childrestraint say that the top strap mustbe anchored.

If the child restraint or vehicle seatposition does not have the LATCHsystem, you will be using the seat beltto secure the child restraint. Be sureto follow the instructions that camewith the child restraint.

If more than one child restraint needsto be installed in the rear seat, be sureto read Where to Put the Restraint0 103.

Emissions Inspection andMaintenance Programs

If the vehicle requires an EmissionsInspection/Maintenance test, the testequipment will likely connect to thevehicle's Data Link Connector (DLC).

The DLC is under the instrumentpanel to the left of the steering wheel.Connecting devices that are not usedto perform an Emissions Inspection/Maintenance test or to service thevehicle may affect vehicle operation.See Add-On Electrical Equipment 0 315.See your dealer if assistance is needed.

The vehicle may not passinspection if:

. The light is on when the engine isrunning.

. The light does not come on whenthe ignition is in Service Mode.

. Critical emission control systemshave not been completelydiagnosed. If this happens, thevehicle would not be ready forinspection and might requireseveral days of routine drivingbefore the system is ready forinspection. This can happen if the12-volt battery has recently beenreplaced or run down, or if thevehicle has been recently serviced.

See your dealer if the vehicle will notpass or cannot be made ready forthe test.

. Charging an electric vehicle canstress a building’s electricalsystem more than a typicalhousehold appliance.

. Before you plug in to any electricaloutlet, have a qualified electricianinspect and verify the electricalsystem (electrical outlet, wiring,junctions, and protection devices)for heavy-duty service at a 12 ampcontinuous load.

. Electrical outlets may wear outwith normal usage or be damagedover time, making them unsuitablefor electric vehicle charging.

. Check the electrical outlet/plugwhile charging and discontinueuse if the electrical outlet/plug ishot, then have the electrical outletserviced by a qualified electrician.

. When outdoors, plug into anelectrical outlet that isweatherproof while in use.

. Mount the charging cord to reducestrain on the electrical outlet/plug.

{ Danger

Improper use of portable electricvehicle charge cords may cause afire, electrical shock, or burns, andmay result in damage to property,serious injury, or death.

. Do not use extension cords,multi-outlet power strips,splitters, grounding adaptors,surge protectors, or similardevices.

. Do not use an electrical outletthat is worn or damaged,or will not hold the plugfirmly in place.

. Do not use an electrical outletthat is not properly grounded.

. Do not use an electrical outletthat is on a circuit with otherelectrical loads.

The Charge Start and ChargeComplete time estimates are alsodisplayed on the screen. Theseestimates are most accurate when thevehicle is plugged in and in moderatetemperature conditions. Also, to getan accurate time estimate, the vehicleuses an internal clock forprogrammable charging, not the clockin the infotainment display.

Charge Mode Status

Immediately : The vehicle startscharging as soon as it is connected toan electrical outlet. See Plug-InCharging (PLUG-IN Only) 0 292.

Delay Charge Based on DepartureTime : The vehicle estimates thecharging start time considering theprogrammed departure time for the

current day of the week. Chargingbegins at the start time and iscomplete by the departure time only ifsufficient time is allowed after thecharge cord is plugged in.

Delay (Electric Rate and DepartureTime) : The vehicle estimates thecharging start time based on theutility rate schedule, utility ratepreference, and the programmeddeparture time for the current day ofthe week. The vehicle will chargeduring the least expensive rate periodsto achieve a full battery charge by thedeparture time. Electrical rateinformation from the utility companyfor the charging location is requiredfor this mode.

Charge Limit Selection

The Charge Limit Preference settingallows the customer to select theirvehicle’s charge level so it matches thecapability of their charging location.If the vehicle consistently stopscharging after plugging in, or if acircuit breaker continues to trip,reducing to a lower Charge LimitPreference may resolve the issue.

The Charge Limit Preference should beconfigured to match the electricalcurrent rating for the electrical outletthat the charge cord is connected to.The Charge Limit Preferencesettings are:

. Maximum: Limits AC current to12 amps

. Reduced: Limits AC current to8 amps

Exact current levels may vary fromthe values shown in this manual.Check the vehicle for the currentavailable levels.

The Charge Limit Preference settingcan be changed at any time while theinfotainment display is operable.

For some vehicles, the Charge LimitPreference must be updated prior tothe vehicle being charged and theCharge Limit Preference will reset to adefault value when the vehicle isshifted from P (Park).

{ Warning

Using a charge level that exceedsthe electrical circuit or electricaloutlet capacity may start a fire ordamage the electrical circuit. Usethe lowest charge level until aqualified electrician inspects theelectrical circuit capacity. Use thelowest charge level if the electricalcircuit or electrical outlet capacityis not known.

instructions refer to a garage dooropener, but can be used for otherdevices.

Do not use the Universal Remotesystem with any garage door openerthat does not have the stop andreverse feature. This includes anygarage door opener modelmanufactured before April 1, 1982.

Read these instructions completelybefore programming the UniversalRemote system. It may help to haveanother person assist with theprogramming process.

Keep the original hand-heldtransmitter for use in other vehiclesas well as for future programming.Erase the programming when vehicleownership is terminated. See “ErasingUniversal Remote System Buttons”later in this section.

To program a garage door opener,park outside directly in line with andfacing the garage door opener receiver.Clear all people and objects near thegarage door.

Make sure the hand-held transmitterhas a new battery for quick andaccurate transmission of theradio-frequency signal.

Programming the UniversalRemote System

For questions or programming help,see www.homelink.com/gm or call1-800-355-3515.

Programming involves time-sensitiveactions, and may time out causing theprocedure to be repeated.

To program up to three devices:

1. Hold the end of the hand-heldtransmitter about 3 to 8 cm (1 to3 in) away from the UniversalRemote system buttons with theindicator light in view. Thehand-held transmitter wassupplied by the manufacturer ofthe garage door opener receiver.

2. At the same time, press and holdboth the hand-held transmitterbutton and one of the threeUniversal Remote systembuttons to be used to operate thegarage door. Do not release either

button until the indicator lightchanges from a slow to a rapidflash. Then release both buttons.

Some garage door openers mayrequire substitution of Step 2with the procedure under “RadioSignals for Canada and SomeGate Operators” later in thissection.

3. Press and hold the newlyprogrammed Universal Remotesystem button for five secondswhile watching the indicatorlight and garage door activation.

. If the indicator light stays oncontinuously or the garagedoor moves when the buttonis pressed, then programmingis complete. There is no needto complete Steps 4–6.

. If the indicator light does notcome on or the garage doordoes not move, a secondbutton press may berequired. For a second time,press and hold the newlyprogrammed button for

five seconds. If the light stayson or the garage door moves,programming is complete.

. If the indicator light blinksrapidly for two seconds, thenchanges to a solid light andthe garage door does notmove, continue withprogramming Steps 4–6.

Learn or Smart Button

4. After completing Steps 1–3,locate the Learn or Smart buttoninside the garage on the garagedoor opener receiver. The nameand color of the button may varyby manufacturer.

5. Press and release the Learn orSmart button. Step 6 must becompleted within 30 seconds ofpressing this button.

6. Inside the vehicle, press and holdthe newly programmed UniversalRemote system button fortwo seconds and then release it.If the garage door does not moveor the lamp on the garage dooropener receiver does not flash,press and hold the same buttona second time for two seconds,then release it. Again, if the doordoes not move or the garagedoor lamp does not flash, pressand hold the same button a thirdtime for two seconds, thenrelease it.

The Universal Remote system shouldnow activate the garage door.

Repeat the process for programmingthe two remaining buttons.

Radio Signals for Canada andSome Gate Operators

For questions or programming help,see www.homelink.com/gm or call1-800-355-3515.

Canadian radio-frequency laws andsome U.S. gate operators requiretransmitter signals to time out or quitafter several seconds of transmission.This may not be long enough for theUniversal Remote system to pick upthe signal during programming.

If the programming did not work,replace Step 2 under “Programmingthe Universal Remote System” withthe following:

Press and hold the Universal Remotesystem button while pressing andreleasing the hand-held transmitterbutton every two seconds until thesignal has been successfully acceptedby the Universal Remote system. TheUniversal Remote system indicatorlight will flash slowly at first and thenrapidly. Proceed with Step 3 under“Programming the Universal RemoteSystem” to complete.

If the vehicle has remained parked foran extended period of time with noRKE transmitter use or Keyless Accessoperation, approach detection will bedisabled. To reactivate, press anybutton on the RKE transmitter oropen and close all vehicle doors tore-enable the entry lighting feature onapproach.

Approach detection will not work if:

. The vehicle battery is low.

. The ignition is on or in ACC/ACCESSORY.

. Entry lighting is set to Off. See“Vehicle Locator Lights” underVehicle Personalization 0 171.

Approach detection will not work witha single RKE transmitter if:

. The RKE transmitter is left withina 5 m (16 ft) range of the vehiclefor several minutes

. The RKE transmitter is left insidethe vehicle and all the doors areclosed

To help maximize transmitter batterylife, do not store the transmitterwithin 5 m (16 ft) of the vehicle.

Exit LightingSome exterior lamps and interiorlights come on at night, or in areaswith limited lighting, when the driverdoor is opened after the ignition isturned off. The dome lamp comes onafter the ignition is turned off. Theexterior lamps and dome lamp remainon for a set amount of time, thenautomatically turn off.

The exterior lamps turn offimmediately by turning the exteriorlamp control off.

This feature can be changed. SeeVehicle Personalization 0 171.

LIGHTING 191

Battery Load ManagementThe vehicle has Electric PowerManagement (EPM) that estimates thebattery's temperature and state ofcharge. It then adjusts the voltage forbest performance and extended life ofthe battery.

When the battery's state of charge islow, the voltage is raised slightly toquickly bring the charge back up.When the state of charge is high, thevoltage is lowered slightly to preventovercharging. If the vehicle has avoltmeter gauge or a voltage displayon the Driver Information Center(DIC), you may see the voltage moveup or down. This is normal. If there isa problem, an alert will be displayed.

The battery can be discharged at idleif the electrical loads are very high.This is true for all vehicles. This isbecause the generator (alternator)may not be spinning fast enough atidle to produce all of the powerneeded for very high electrical loads.

A high electrical load occurs whenseveral of the following are on, suchas: headlamps, high beams, rear

window defogger, climate control fanat high speed, heated seats, enginecooling fans, trailer loads, and loadsplugged into accessory power outlets.

EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speed togenerate more power wheneverneeded. It can temporarily reduce thepower demands of some accessories.

Normally, these actions occur in stepsor levels, without being noticeable. Inrare cases at the highest levels ofcorrective action, this action may benoticeable to the driver. If so, a DICmessage might be displayed and it isrecommended that the driver reducethe electrical loads as much aspossible.

Battery Power ProtectionThe battery saver feature is designedto protect the vehicle's battery.

If some interior lamps are left on andthe ignition is turned off, the batteryrundown protection systemautomatically turns the lamp off aftersome time.

Exterior Lighting BatterySaverThe exterior lamps turn off about10 minutes after the ignition is turnedoff, if the parking lamps or headlampshave been manually left on. Thisprotects against draining the battery.To restart the 10-minute timer, turnthe exterior lamp control to the offposition and then back to the parkinglamp or headlamp position.

To keep the lamps on for more than10 minutes, the ignition must be on orin ACC/ACCESSORY.

Operation Tips

. Clear away any ice, snow, or leavesfrom air inlets at the base of thewindshield that could block theflow of air into the vehicle.

. Clear snow off the hood toimprove visibility and helpdecrease moisture drawn into thevehicle.

. Keep the path under the frontseats clear of objects to helpcirculate the air inside of thevehicle more effectively.

. Use of non-GM approved hooddeflectors can adversely affect theperformance of the system. Checkwith your dealer before addingequipment to the outside of thevehicle.

. Do not attach any devices to theair vent slats. This restricts airflowand may cause damage to the airvents.

Maintenance

Passenger CompartmentAir FilterThe filter reduces dust, pollen, andother airborne irritants from outsideair that is pulled into the vehicle. Thefilter should be replaced as part ofroutine scheduled maintenance. SeeMaintenance Schedule 0 415.

See your dealer regarding replacementof the filter.

ServiceAll vehicles have a label underhoodthat identifies the refrigerant used inthe vehicle. The refrigerant systemshould only be serviced by trained andcertified technicians. The airconditioning evaporator should neverbe repaired or replaced by one from asalvage vehicle. It should only bereplaced by a new evaporator toensure proper and safe operation.

During service, all refrigerants shouldbe reclaimed with proper equipment.Venting refrigerants directly to theatmosphere is harmful to theenvironment and may also createunsafe conditions based on inhalation,combustion, frostbite, or otherhealth-based concerns.

Driving Information

Distracted DrivingDistraction comes in many forms andcan take your focus from the task ofdriving. Exercise good judgment anddo not let other activities divert yourattention away from the road. Manylocal governments have enacted lawsregarding driver distraction. Becomefamiliar with the local laws inyour area.

To avoid distracted driving, keep youreyes on the road, keep your hands onthe steering wheel, and focus yourattention on driving.

. Do not use a phone in demandingdriving situations. Use ahands-free method to place orreceive necessary phone calls.

. Watch the road. Do not read, takenotes, or look up information onphones or other electronic devices.

. Designate a front seat passengerto handle potential distractions.

DRIVING AND OPERATING 209. Become familiar with vehicle

features before driving, such asprogramming favorite radiostations and adjusting climatecontrol and seat settings. Programall trip information into anynavigation device prior to driving.

. Wait until the vehicle is parked toretrieve items that have fallen tothe floor.

. Stop or park the vehicle to tend tochildren.

. Keep pets in an appropriate carrieror restraint.

. Avoid stressful conversationswhile driving, whether with apassenger or on a cell phone.

{ Warning

Taking your eyes off the road toolong or too often could cause acrash resulting in injury or death.Focus your attention on driving.

Refer to the infotainment section formore information on using thatsystem and the navigation system,if equipped, including pairing andusing a cell phone.

Defensive DrivingDefensive driving means “alwaysexpect the unexpected.” The first stepin driving defensively is to wear theseat belt. See Seat Belts 0 79.

. Assume that other road users(pedestrians, bicyclists, and otherdrivers) are going to be carelessand make mistakes. Anticipatewhat they might do and be ready.

. Allow enough following distancebetween you and the driver infront of you.

. Focus on the task of driving.

Drunk DrivingDeath and injury associated withdrinking and driving is a globaltragedy.

{ Warning

Drinking and then driving is verydangerous. Your reflexes,perceptions, attentiveness, andjudgment can be affected by even asmall amount of alcohol. You canhave a serious — or even fatal —collision if you drive after drinking.

Do not drink and drive or ride witha driver who has been drinking.Ride home in a cab; or if you arewith a group, designate a driverwho will not drink.

Control of a VehicleBraking, steering, and accelerating areimportant factors in helping to controla vehicle while driving.

Braking (Gasoline Only)Braking action involves perceptiontime and reaction time. Deciding topush the brake pedal is perceptiontime. Actually doing it isreaction time.

Page 211: C M Y CM MY CY CMY K - cadillac.com · Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) - 2018 - CRC - 3/1/18 INTRODUCTION 3 {WarningWarning indicates a hazard that

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) -2018 - CRC - 3/1/18

210 DRIVING AND OPERATING

Average driver reaction time is aboutthree-quarters of a second. In thattime, a vehicle moving at 100 km/h(60 mph) travels 20 m (66 ft), whichcould be a lot of distance in anemergency.

Helpful braking tips to keep in mindinclude:

. Keep enough distance betweenyou and the vehicle in frontof you.

. Avoid needless heavy braking.

. Keep pace with traffic.

If the engine ever stops while thevehicle is being driven, brake normallybut do not pump the brakes. Doing socould make the pedal harder to pushdown. If the engine stops, there willbe some power brake assist but it willbe used when the brake is applied.Once the power assist is used up, itcan take longer to stop and the brakepedal will be harder to push.

. Avoid needless heavy braking.

. Keep pace with traffic.

The brake system is not affected bywhether or not the engine is running.If there is a brake controller fault, thebrakes may lose power assist. Moreeffort will be required to stop thevehicle.

Steering

Variable Effort Steering

The vehicle has a steering system thatvaries the amount of effort required tosteer the vehicle in relation to thespeed of the vehicle.

The amount of steering effort requiredis less at slower speeds to make thevehicle more maneuverable and easierto park. At faster speeds, the steeringeffort increases to provide a sport-likefeel to the steering. This providesmaximum control and stability.

Electric Power Steering

The vehicle has electric powersteering. It does not have powersteering fluid. Regular maintenance isnot required.

If power steering assist is lost due to asystem malfunction, the vehicle canbe steered, but may require increasedeffort. See your dealer if there is aproblem.

Page 212: C M Y CM MY CY CMY K - cadillac.com · Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) - 2018 - CRC - 3/1/18 INTRODUCTION 3 {WarningWarning indicates a hazard that

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) -2018 - CRC - 3/1/18

DRIVING AND OPERATING 211

If the steering wheel is turned until itreaches the end of its travel and isheld against that position for anextended period of time, powersteering assist may be reduced.

If the steering assist is used for anextended period of time while thevehicle is not moving, power assistmay be reduced.

Normal use of the power steeringassist should return when the systemcools down.

See your dealer if there is a problem.

Curve Tips. Take curves at a reasonable speed.

. Reduce speed before entering acurve.

. Maintain a reasonable steadyspeed through the curve.

. Wait until the vehicle is out of thecurve before accelerating gentlyinto the straightaway.

Steering in Emergencies. There are some situations when

steering around a problem may bemore effective than braking.

. Holding both sides of the steeringwheel allows you to turn180 degrees without removinga hand.

. Antilock Brake System (ABS)allows steering while braking.

Off-Road Recovery

The vehicle's right wheels can drop offthe edge of a road onto the shoulderwhile driving. Follow these tips:

1. Ease off the accelerator and then,if there is nothing in the way,steer the vehicle so that itstraddles the edge of thepavement.

2. Turn the steering wheel aboutone-eighth of a turn, until theright front tire contacts thepavement edge.

3. Turn the steering wheel to gostraight down the roadway.

Loss of Control

Skidding

There are three types of skids thatcorrespond to the vehicle's threecontrol systems:

. Braking Skid — wheels are notrolling.

. Steering or Cornering Skid — toomuch speed or steering in a curvecauses tires to slip and losecornering force.

. Acceleration Skid — too muchthrottle causes the driving wheelsto spin.

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) -2018 - CRC - 3/1/18

212 DRIVING AND OPERATING

Defensive drivers avoid most skids bytaking reasonable care suited toexisting conditions, and by notoverdriving those conditions. Butskids are always possible.

If the vehicle starts to slide, followthese suggestions:

. Ease your foot off the acceleratorpedal and steer the way you wantthe vehicle to go. The vehicle maystraighten out. Be ready for asecond skid if it occurs.

. Slow down and adjust your drivingaccording to weather conditions.Stopping distance can be longerand vehicle control can be affectedwhen traction is reduced by water,snow, ice, gravel, or other materialon the road. Learn to recognizewarning clues — such as enoughwater, ice, or packed snow on theroad to make a mirrored surface— and slow down when you haveany doubt.

. Try to avoid sudden steering,acceleration, or braking, includingreducing vehicle speed by shifting

to a lower gear. Any suddenchanges could cause the tires toslide.

Remember: Antilock brakes help avoidonly the braking skid.

Driving on Wet RoadsRain and wet roads can reduce vehicletraction and affect your ability to stopand accelerate. Always drive slower inthese types of driving conditions andavoid driving through large puddlesand deep-standing or flowing water.

{ Warning

Wet brakes can cause crashes. Theymight not work as well in a quickstop and could cause pulling to oneside. You could lose control of thevehicle.

After driving through a large puddleof water or a car/vehicle wash,lightly apply the brake pedal untilthe brakes work normally.

(Continued)

Warning (Continued)

Flowing or rushing water createsstrong forces. Driving throughflowing water could cause thevehicle to be carried away. If thishappens, you and other vehicleoccupants could drown. Do notignore police warnings and be verycautious about trying to drivethrough flowing water.

Hydroplaning

Hydroplaning is dangerous. Water canbuild up under the vehicle's tires sothey actually ride on the water. Thiscan happen if the road is wet enoughand you are going fast enough. Whenthe vehicle is hydroplaning, it haslittle or no contact with the road.

There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.

DRIVING AND OPERATING 213

Other Rainy Weather Tips

Besides slowing down, other wetweather driving tips include:

. Allow extra following distance.

. Pass with caution.

. Keep windshield wiping equipmentin good shape.

. Keep the windshield washer fluidreservoir filled.

. Have good tires with proper treaddepth. See Tires 0 362.

. Turn off cruise control.

Hill and Mountain RoadsDriving on steep hills or throughmountains is different than driving onflat or rolling terrain. Tips include:

. Keep the vehicle serviced and ingood shape.

. Check all fluid levels and brakes,tires, cooling system, andtransmission.

. Shift to a lower gear when goingdown steep or long hills.

{ Warning

Using the brakes to slow the vehicleon a long downhill slope can causebrake overheating, can reduce brakeperformance, and could result in aloss of braking. Shift thetransmission to a lower gear to letthe engine assist the brakes on asteep downhill slope.

{ Warning

Coasting downhill in N (Neutral) orwith the ignition off is dangerous.This can cause overheating of thebrakes and loss of steering assist.Always have the engine runningand the vehicle in gear.

. Drive at speeds that keep thevehicle in its own lane. Do notswing wide or cross thecenter line.

. Be alert on top of hills; somethingcould be in your lane (e.g., stalledcar, accident).

. Pay attention to special road signs(e.g., falling rocks area, windingroads, long grades, passing orno-passing zones) and takeappropriate action.

Winter Driving

Driving on Snow or Ice

Snow or ice between the tires and theroad creates less traction or grip, sodrive carefully. Wet ice can occur atabout 0 °C (32 °F) when freezing rainbegins to fall. Avoid driving on wet iceor in freezing rain until roads can betreated.

For slippery road driving:

. Accelerate gently. Accelerating tooquickly causes the wheels to spinand makes the surface under thetires slick.

. Turn on Traction Control. SeeTraction Control/Electronic StabilityControl 0 242.

214 DRIVING AND OPERATING. Antilock Brake System (ABS)

improves vehicle stability duringhard stops, but the brakes shouldbe applied sooner than when ondry pavement. See Antilock BrakeSystem (ABS) 0 237.

See Driver Mode Control (GasolineOnly) 0 244.

. Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwiseclear roads in shaded areas. Thesurface of a curve or an overpasscan remain icy when thesurrounding roads are clear. Avoidsudden steering maneuvers andbraking while on ice.

. Turn off cruise control.

Blizzard Conditions

Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby. If possible,use Roadside Service. See RoadsideService 0 437. To get help and keepeveryone in the vehicle safe:

. Turn on the hazard warningflashers.

. Tie a red cloth to an outsidemirror.

{ Warning

Snow can trap engine exhaustunder the vehicle. This may causeexhaust gases to get inside. Engineexhaust contains carbon monoxide(CO), which cannot be seen orsmelled. It can causeunconsciousness and even death.

If the vehicle is stuck in snow:

. Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.

. Open a window about 5 cm(2 in) on the vehicle side thatis away from the wind, tobring in fresh air.

. Fully open the air outlets onor under the instrumentpanel.

. Adjust the climate controlsystem to circulate the airinside the vehicle and set the

(Continued)

fan speed to the highestsetting. See “Climate ControlSystems.”

For more information about CO, seeEngine Exhaust 0 232.

To save fuel, run the engine for shortperiods to warm the vehicle and thenshut the engine off and partially closethe window. Moving about to keepwarm also helps.

If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idle speed.This keeps the battery charged torestart the vehicle and to signal forhelp with the headlamps. Do this aslittle as possible, to save fuel.

If the Vehicle Is StuckSlowly and cautiously spin the wheelsto free the vehicle when stuck in sand,mud, ice, or snow.

DRIVING AND OPERATING 215

If stuck too severely for the tractionsystem to free the vehicle, turn thetraction system off and use therocking method. See Traction Control/Electronic Stability Control 0 242.

{ Warning

If the vehicle's tires spin at highspeed, they can explode, and you orothers could be injured. The vehiclecan overheat, causing an enginecompartment fire or other damage.Spin the wheels as little as possibleand avoid going above 56 km/h(35 mph).

Rocking the Vehicle to Get it Out

Turn the steering wheel left and rightto clear the area around the frontwheels. Turn off any traction system.Shift back and forth betweenR (Reverse) and a low forward gear,spinning the wheels as little aspossible. To prevent transmissionwear, wait until the wheels stopspinning before shifting gears. Releasethe accelerator pedal while shifting,and press lightly on the accelerator

pedal when the transmission is ingear. Slowly spinning the wheels inthe forward and reverse directionscauses a rocking motion that couldfree the vehicle. If that does not getthe vehicle out after a few tries, itmight need to be towed out. If thevehicle does need to be towed out, seeTowing the Vehicle 0 400.

Vehicle Load LimitsIt is very important to know howmuch weight the vehicle can carry.This weight is called the vehiclecapacity weight and includes theweight of all occupants, cargo, andall nonfactory-installed options.Two labels on the vehicle mayshow how much weight it mayproperly carry: the Tire andLoading Information label and theCertification label.

{ Warning

Do not load the vehicle anyheavier than the Gross VehicleWeight Rating (GVWR),or either the maximum front orrear Gross Axle Weight Rating(GAWR). This can causesystems to break and changethe way the vehicle handles.This could cause loss of controland a crash. Overloading canalso reduce stopping distance,damage the tires, and shortenthe life of the vehicle.

Tire and Loading InformationLabel

Label Example

A vehicle-specific Tire andLoading Information label isattached to the vehicle's centerpillar (B-pillar). The Tire andLoading Information label showsthe number of occupant seatingpositions (1), and the maximumvehicle capacity weight (2) inkilograms and pounds.

The Tire and Loading Informationlabel also shows the tire size ofthe original equipment tires (3)and the recommended cold tireinflation pressures (4). For moreinformation on tires and inflationsee Tires 0 362 and Tire Pressure0 369.

There is also important loadinginformation on the Certificationlabel. It may show the GrossVehicle Weight Rating (GVWR)and the Gross Axle Weight Rating(GAWR) for the front and rearaxle. See “Certification Label” laterin this section.

“Steps for Determining CorrectLoad Limit–

1. Locate the statement "Thecombined weight ofoccupants and cargo shouldnever exceed XXX kg orXXX lbs." on your vehicle’splacard.

2. Determine the combinedweight of the driver andpassengers that will be ridingin your vehicle.

3. Subtract the combined weightof the driver and passengersfrom XXX kg or XXX lbs.

4. The resulting figure equalsthe available amount of cargoand luggage load capacity. Forexample, if the "XXX" amountequals 1400 lbs. and therewill be five 150 lb passengersin your vehicle, the amountof available cargo and luggageload capacity is 650 lbs.(1400-750 (5 x 150) =650 lbs.)

5. Determine the combinedweight of luggage and cargobeing loaded on the vehicle.That weight may not safelyexceed the available cargoand luggage load capacitycalculated in Step 4.

Starting and Operating

New Vehicle Break-In(Gasoline Engine Only)Follow these recommended guidelinesduring the first 2 400 km (1,500 mi) ofdriving this vehicle. Parts have abreak-in period and performance willbe better in the long run.

For the first 2 400 km (1,500 mi):

. Avoid full throttle starts andabrupt stops.

. Do not exceed 4000 engine rpm.

. Avoid driving at any one constantspeed, fast or slow.

. Avoid downshifting to brake orslow the vehicle when the enginespeed will exceed 4000 rpm.

. Do not let the engine labor. Neverlug the engine in high gear at lowspeeds.

. Do not participate in track events,sport driving schools, or similaractivities during this break-inperiod.

. Check engine oil with everyrefueling and add if necessary. Oiland fuel consumption may behigher than normal during thefirst 2 400 km (1,500 mi).

. To break in new tires, drive atmoderate speeds and avoid hardcornering for the first300 km (200 mi). New tires do nothave maximum traction and maytend to slip.

. New brake linings also need abreak–in period. Avoid makinghard stops during the first300 km (200 mi). This isrecommended every time brakelinings are replaced.

Ignition Positions

The vehicle has an electronic keylessignition with pushbutton start.

The Remote Keyless Entry (RKE)transmitter must be in the vehicle forthe system to operate. If thepushbutton start is not working, thevehicle may be near a strong radioantenna signal causing interference tothe Keyless Access system. See RemoteKeyless Entry (RKE) System Operation0 35.

If EMM is required and the fuel levelis low, EMM may eventually emptythe fuel tank if fuel is not added. Thiswill result in reduced, or no power. Anadequate fuel level must bemaintained in the vehicle to keep itoperational.

Fuel Maintenance Mode (FMM)

FMM tracks average fuel age. Old fuelcan cause engine problems. If lowengine usage causes average fuel ageto exceed approximately one year,FMM will run the engine to use upthe old fuel. The engine will run untilenough fresh fuel is added to bringthe average fuel age into anacceptable range. Allowing more oldfuel to be used up by FMM andadding a larger amount of fresh fuelwill maximize the length of timebefore another fuel maintenancemode is needed. During FMM theengine may turn on and off.

To enter Permanent Tap Shift Mode:

1. Move the shift lever fromD (Drive) to M (Manual Mode).While in Tap Shift Mode, the Mon the PRNDM section of theinstrument cluster will becomehighlighted, and the current gearis indicated.

2. Tap the left control toward thedriver to downshift, and the rightcontrol toward the driver toupshift. To shift to the lowestavailable gear, press and hold theleft control.

3. To exit, move the shift lever backto D (Drive).

With the shift lever in D (Drive) andnot in Permanent Tap Shift Mode, theTap Shift controls will activate atemporary tap manual shift mode,allowing the transmission to bemanually shifted. The vehicle exitsTemporary Tap Shift Mode after theaccelerator pedal is steady forsix seconds. Temporary Tap ShiftMode holds a gear longer withoutexiting when coasting, to providepowertrain braking. The TemporaryTap Shift Mode can also bedeactivated by holding the rightupshift control briefly.

While using Tap Shift, the vehicle willhave firmer, quicker shifting. You canuse this for sport driving or whenclimbing or descending hills, to stay ingear longer, or to downshift for morepower or engine braking.

The transmission will only allow youto shift into gears appropriate for thevehicle speed and engine revolutionsper minute (rpm). The transmissionwill not downshift if the engine rpm istoo high in the next lower gear,or upshift to the next higher gearwhen the maximum engine rpm isreached.

If shifting is prevented for any reason,a SHIFT DENIED message will bedisplayed in the instrument cluster.

When accelerating the vehicle from astop in snowy and icy conditions, it issuggested to shift into second gear.A higher gear allows the vehicle togain more traction on slipperysurfaces.

DRIVING AND OPERATING 237

Drive Systems

All-Wheel DriveVehicles with this feature always sendengine power to all four wheels. It isfully automatic, and adjusts itself asneeded for road conditions.

Brakes

Antilock BrakeSystem (ABS)This vehicle has an Antilock BrakeSystem (ABS), an advanced electronicbraking system that helps prevent abraking skid.

When the vehicle begins to driveaway, ABS checks itself. A momentarymotor or clicking noise may be heardwhile this test is going on, and it mayeven be noticed that the brake pedalmoves a little. This is normal.

If there is a problem with ABS, thiswarning light stays on. See AntilockBrake System (ABS) Warning Light0 147.

If driving safely on a wet road and itbecomes necessary to slam on thebrakes and continue braking to avoida sudden obstacle, a computer sensesthe wheels are slowing down. If one ofthe wheels is about to stop rolling, thecomputer will separately work thebrakes at each wheel.

ABS can change the brake pressure toeach wheel, as required, faster thanany driver could. This can help yousteer around the obstacle whilebraking hard.

As the brakes are applied, thecomputer keeps receiving updates onwheel speed and controls brakingpressure accordingly.

Remember: ABS does not change thetime needed to get a foot up to thebrake pedal or always decreasestopping distance. If you get too closeto the vehicle in front of you, therewill not be enough time to apply thebrakes if that vehicle suddenly slowsor stops. Always leave enough roomup ahead to stop, even with ABS.

238 DRIVING AND OPERATING

Using ABS

Do not pump the brakes. Just hold thebrake pedal down firmly and let ABSwork. You may hear the ABS pump ormotor operating and feel the brakepedal pulsate. This is normal.

Braking in Emergencies

ABS allows you to steer and brake atthe same time. In many emergencies,steering can help more than even thevery best braking.

Electric Parking Brake

The vehicle has an Electric ParkingBrake (EPB). The EPB can always beactivated, even if the ignition is off. Toprevent draining the battery, avoidrepeated cycles of the EPB systemwhen the engine is not running.

The system has aY or PARK

Electric Parking Brake light, and a 8Service Parking Brake light.See Electric Parking Brake Light 0 146and Service Electric Parking Brake Light0 146.

Before leaving the vehicle, check fortheY or PARK light to ensure thatthe parking brake is applied.

EPB Apply

To apply the EPB:

1. Be sure the vehicle is at acomplete stop.

2. Press the EPB switchmomentarily.

TheY or PARK light will flash andthen stay on once the EPB is fullyapplied. If theY or PARK lightflashes continuously, then the EPB is

only partially applied or there is aproblem with the EPB. A DIC messagewill display. Release the EPB and tryto apply it again. If the light does notcome on, or keeps flashing, have thevehicle serviced. Do not drive thevehicle if theY or PARK light isflashing. See your dealer. See ElectricParking Brake Light 0 146.

If the 8 light is on, press the EPBswitch and hold it. Continue to holdthe switch until theY or PARK light

remains on. If the 8 light remains on,see your dealer.

If the EPB is applied while the vehicleis moving, the vehicle will decelerateas long as the switch is pressed. If theswitch is pressed until the vehiclecomes to a stop, the EPB will remainapplied.

The vehicle may automatically applythe EPB in some situations when thevehicle is not moving. This is normal,and is done to periodically check thecorrect operation of the EPB system.

If the EPB fails to apply, block the rearwheels to prevent vehicle movement.

DRIVING AND OPERATING 239

EPB Release

To release the EPB:

1. Turn the ignition on or to ACC/ACCESSORY.

2. Apply and hold the brake pedal.

3. Press the EPB switchmomentarily.

The EPB is released when theY orPARK light is off.

If the 8 light is on, release the EPB bypressing and holding the EPB switch.Continue to hold the switch untiltheY or PARK light is off. If eitherlight stays on after release isattempted, see your dealer.

Caution

Driving with the parking brake oncan overheat the brake system andcause premature wear or damage tobrake system parts. Make sure thatthe parking brake is fully releasedand the brake warning light is offbefore driving.

Automatic EPB Release

The EPB will automatically release ifthe vehicle is running, placed intogear, and an attempt is made to driveaway. Avoid rapid acceleration whenthe EPB is applied, to preserve parkingbrake lining life.

Brake AssistThis vehicle has a brake assist featuredesigned to assist the driver instopping or decreasing vehicle speedin emergency driving conditions. Thisfeature uses the stability systemhydraulic brake control module tosupplement the power brake systemunder conditions where the driver hasquickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle. Thestability system hydraulic brakecontrol module increases brakepressure at each corner of the vehicleuntil the ABS activates. Minor brakepedal pulsation or pedal movementduring this time is normal and thedriver should continue to apply thebrake pedal as the driving situationdictates. The brake assist feature will

automatically disengage when thebrake pedal is released or brake pedalpressure is quickly decreased.

Hill Start Assist (HSA)Hill Start Assist (HSA) mayautomatically activate when thevehicle is stopped on a hill andAutomatic Vehicle Hold (AVH) is notenabled. This feature is designed toprevent the vehicle from rolling, eitherforward or rearward, during vehicledrive off. During the transition fromreleasing the brake pedal toaccelerating to drive off on a hill, HSAholds the braking pressure to preventrolling. HSA will not activate if thevehicle is in a drive gear and facingdownhill or if the vehicle is facinguphill and in R (Reverse).

240 DRIVING AND OPERATING

Automatic VehicleHold (AVH)

Automatic Vehicle Hold (AVH),if equipped, can be turned on bypressing AUTO HOLD with the driverseat belt fastened, the driver doorclosed, and the engine running. TheAVH indicator will come on.

This feature will activate when thevehicle is stopped to prevent it frommoving. After the brake pedal hasbeen released and before theaccelerator pedal has been pressed,AVH uses braking pressure to hold thevehicle stationary. In addition, the

ABS pump motor may activate tobuild brake pressure to maintain thevehicle at a standstill if necessary.

If AVH is holding the vehicle, the AVHindicator will change to green. OnceAVH is active it will hold the vehiclefor a defined time period then engagethe parking brake. While AVH isholding the vehicle, the parking brakewill engage if the driver door isopened or the driver seat belt isunfastened. See Automatic Vehicle Hold(AVH) Light 0 147.

Regenerative Braking(PLUG-IN Only)Regenerative braking takes some ofthe energy from the moving vehicleand turns it back into electricalenergy. This energy is then storedback into the high voltage batterysystem, contributing to increasedenergy efficiency.

The hydraulic disc brakes work withthe regenerative braking to ensureeffective braking, such as when a highbraking demand is requested.

The braking system is computercontrolled and blends the regenerativebraking with the conventionalhydraulic disc brakes to meet anyrequirements for deceleration. Thecontroller interprets the brakingrequest and uses regenerative braking,conventional hydraulic braking, or acombination of both as necessary.Because the hydraulic braking systemuses an electronic booster for boostassist on demand, under certainconditions a motor noise may beheard. This is normal operation.

See Warning Lights, Gauges, andIndicators 0 128 and Driver InformationCenter (DIC) 0 163. In the event of acontroller problem, the brake pedalmay be harder to push and thestopping distance may be longer.

Regen on Demand

Regen on Demand allows the user toselect increased coast deceleration bypressing the steering wheel tapcontrols. It is activated temporarilywhile in D (Drive) and permanentlywhile in M (Manual Mode). Increasedcoast deceleration will be felt while

242 DRIVING AND OPERATING

While using Regen on Demand, thevehicle will have increased coastdeceleration. Use this to maximizeregenerative braking, for sport driving,or when descending hills.

Propulsion Creep Speed Feature

The PLUG-IN vehicle allows thecoasting speed to be selected whenthe accelerator or brake pedal is notheld. When in either TemporaryRegen on Demand, or when the shiftlever is placed into M in PermanentRegen on Demand, the creep speedcan be decreased from M4 (fastest) toM1 (slowest).

Ride Control Systems

Traction Control/ElectronicStability Control

System Operation

The vehicle has a Traction ControlSystem (TCS) and StabiliTrak, anelectronic stability control system.These systems help limit wheel spinand assist the driver in maintainingcontrol, especially on slippery roadconditions.

TCS activates if it senses that any ofthe drive wheels are spinning orbeginning to lose traction. When thishappens, TCS applies the brakes to thespinning wheels and reduces enginepower to limit wheel spin.

StabiliTrak activates when the vehiclesenses a difference between theintended path and the direction thevehicle is actually traveling.StabiliTrak selectively applies brakingpressure to any one of the vehiclewheel brakes to assist the driver inkeeping the vehicle on theintended path.

If cruise control is being used andtraction control or StabiliTrak beginsto limit wheel spin, cruise control willdisengage. Cruise control may beturned back on when road conditionsallow.

Both systems come on automaticallywhen the vehicle is started and beginsto move. The systems may be heard orfelt while they are operating or whileperforming diagnostic checks. This isnormal and does not mean there is aproblem with the vehicle.

It is recommended to leave bothsystems on for normal drivingconditions, but it may be necessary toturn TCS off if the vehicle gets stuckin sand, mud, ice, or snow. See If theVehicle Is Stuck 0 214 and “Turningthe Systems Off and On” later in thissection.

While pressing the accelerator pedalor shortly following the release tooverride cruise, briefly applying SET−will result in cruise set to the currentvehicle speed.

Using Cruise Control on Hills

How well the cruise control will workon hills depends upon the vehiclespeed, load, and the steepness of thehills. When going up steep hills, youmight have to step on the acceleratorpedal to maintain your speed. Whengoing downhill, the cruise controlsystem may automatically brake toslow the vehicle down. Also, you mayhave to brake or shift to a lower gearto keep your speed down. If the brakepedal is applied, cruise controldisengages.

Ending Cruise Control

There are four ways to end cruisecontrol:

. Step lightly on the brake pedal.

. Press*.

. Shift the transmission toN (Neutral).

. PressJ.

Erasing Speed Memory

The cruise control set speed is erasedfrom memory ifJ is pressed or ifthe ignition is turned off.

Adaptive Cruise ControlIf equipped with Adaptive CruiseControl (ACC), it allows for selectingthe cruise control set speed andfollowing gap. Read this entire sectionbefore using this system. ACC uses acamera and radar sensors to detectother vehicles. See Radio FrequencyStatement 0 443. The following gap isthe following time (or distance)between your vehicle and a vehicledetected directly ahead in your path,

Alerting the Driver

If ACC is engaged, driver action maybe required when ACC cannot applysufficient braking because ofapproaching a vehicle too rapidly.

When this condition occurs, thecollision alert symbol on the HUD willflash on the windshield. Either eightbeeps will sound from the front,or both sides of the Safety Alert Seatwill pulse five times. See “Collision/Detection Systems” under VehiclePersonalization 0 171.

See Defensive Driving 0 209.

Approaching and Following aVehicle

The vehicle ahead indicator is on theinstrument cluster and HUD display.This indicator only displays when avehicle is detected in your vehicle’spath moving in the same direction.

If this indicator is not displaying, ACCwill not respond to or brake forvehicles ahead.

ACC automatically slows the vehicledown and adjusts vehicle speed tofollow the vehicle in front at theselected follow gap. The vehicle speedincreases or decreases to follow thevehicle in front of you, but will notexceed the set speed. It may applylimited braking, if necessary. Whenbraking is active, the brake lamps willcome on. The automatic braking may

feel or sound different than if thebrakes were applied manually. This isnormal.

Stationary or Very Slow-MovingObjects

{ Warning

ACC may not detect and react tostopped or slow-moving vehiclesahead of you. For example, thesystem may not brake for a vehicleit has never detected moving. Thiscan occur in stop-and-go traffic orwhen a vehicle suddenly appearsdue to a vehicle ahead changinglanes. Your vehicle may not stopand could cause a crash. Usecaution when using ACC. Yourcomplete attention is alwaysrequired while driving and youshould be ready to take action andapply the brakes.

Attention to the Road

{ Warning

Super Cruise is a driver assistancesystem and cannot accuratelydetect or predict all situations.Super Cruise is not a crashavoidance system. To preventserious injury or death, you mustsupervise the driving task andmonitor the freeway conditions.You may need to respond to trafficevents by steering, braking,or accelerating. See DefensiveDriving 0 209. Super Cruise alsocannot determine whether you areawake, asleep, impaired, or properlyfocused on safe driving. The vehiclecould crash into other vehicles,drive out of the lane, or drive offthe road. Complete attention isalways required while driving, evenwhile using Super Cruise. Beprepared to take over steering orapply the brakes at any time.

{ Warning

To prevent serious injury or death,be alert and pay special attentionwhen passing freeway exits andentrances with Super Cruise, and beready to take control of the vehiclewhen necessary. Changes in lanemarkings around freeway exits andentrances can momentarily causeSuper Cruise to not detect thecorrect lane. If this occurs, SuperCruise may attempt steering inputsto bring the vehicle back into thecorrect lane and, in rarecircumstances, could over-correctand cause the vehicle tomomentarily cross into a lane nextto your vehicle unless you manuallysteer to maintain your laneposition.

The Driver Attention System (DAS) onthe steering column continuallymonitors driver head and eye positionto estimate driver attention to theroad. The camera does not record orshare pictures, audio, or video.

{ Warning

The Backing Warning System onlyoperates at speeds greater than8 km/h (5 mph). It does not detectchildren, pedestrians, bicyclists,animals, or objects below thebumper or that are too close or toofar from the vehicle. In somesituations, such as at higherbacking speeds, there may not beenough time for the short, sharpapplication of the vehicle brakesystem to occur. To prevent injury,death, or vehicle damage, even withthe Backing Warning System,always check the area around thevehicle and check all mirrors beforebacking.

When the vehicle is in R (Reverse),if the system detects the vehicle isbacking too fast to avoid a crash witha detected object behind your vehiclein your path, it may automaticallybrake hard to a stop to help avoid orreduce the harm caused by a backingcrash.

{ Warning

RAB may not avoid many types ofbacking crashes. Do not wait for theautomatic braking to apply. Thissystem is not designed to replacedriver braking and only works inR (Reverse) when an object isdetected directly behind the vehicle.It may not brake or stop in time toavoid a crash. It will not brake forobjects when the vehicle is movingat very low speeds. It does notdetect children, pedestrians,bicyclists, animals, or objects belowthe bumper or that are too close ortoo far from the vehicle. To preventinjury, death, or vehicle damage,even with RAB, always check thearea around the vehicle before andwhile backing.

If the brake pedal is not pressed soonafter the stop, the Electric ParkingBrake (EPB) may be set. When it issafe, press the accelerator pedal firmlyat any time to override RAB.

{ Warning

There may be instances whereunexpected or undesired automaticbraking occurs. If this happens,either press the brake pedal orfirmly press the accelerator pedal torelease the brakes from the RABsystem. Before releasing the brakes,check the RVC and check the areaaround the vehicle to make sure itis safe to proceed.

Detecting the Vehicle Ahead

FCA warnings will not occur unlessthe FCA system detects a vehicleahead. When a vehicle is detected, thevehicle ahead indicator will displaygreen. Vehicles may not be detectedon curves, highway exit ramps,or hills, due to poor visibility; or if avehicle ahead is partially blocked bypedestrians or other objects. FCA willnot detect another vehicle ahead untilit is completely in the driving lane.

{ Warning

FCA does not provide a warning tohelp avoid a crash, unless it detectsa vehicle. FCA may not detect avehicle ahead if the FCA sensor isblocked by dirt, snow, or ice, or ifthe windshield is damaged. It may

also not detect a vehicle on windingor hilly roads, or in conditions thatcan limit visibility such as fog, rain,or snow, or if the headlamps orwindshield are not cleaned or inproper condition. Keep thewindshield, headlamps, and FCAsensors clean and in good repair.

Collision Alert

With Head-Up Display

Without Head-Up Display

When your vehicle approachesanother detected vehicle too rapidly,the red FCA display will flash on thewindshield. Also, eight rapidhigh-pitched beeps will sound fromthe front, or both sides of the SafetyAlert Seat will pulse five times. Whenthis Collision Alert occurs, the brakesystem may prepare for driver brakingto occur more rapidly which can causea brief, mild deceleration. Continue toapply the brake pedal as needed.Cruise control may be disengagedwhen the Collision Alert occurs.

Tailgating Alert

The vehicle ahead indicator willdisplay amber when you are followinga vehicle ahead much too closely.

Selecting the Alert Timing

The Collision Alert control is on thesteering wheel. Press[ to set theFCA timing to Far, Medium, or Near,or on some vehicles, Off. The firstbutton press shows the current settingon the DIC. Additional button presseswill change this setting. The chosensetting will remain until it is changedand will affect the timing of both theCollision Alert and the TailgatingAlert features. The timing of bothalerts will vary based on vehicle speed.The faster the vehicle speed, thefarther away the alert will occur.Consider traffic and weather

conditions when selecting the alerttiming. The range of selectable alerttimings may not be appropriate for alldrivers and driving conditions.

If your vehicle is equipped withAdaptive Cruise Control (ACC),changing the FCA timing settingautomatically changes the followinggap setting (Far, Medium, or Near).

Following Distance Indicator

The following distance to a movingvehicle ahead in your path is indicatedin following time in seconds on theDriver Information Center (DIC). SeeDriver Information Center (DIC) 0 163.The minimum following time is0.5 seconds away. If there is no vehicledetected ahead, or the vehicle ahead isout of sensor range, dashes will bedisplayed.

Unnecessary Alerts

FCA may provide unnecessary alertsfor turning vehicles, vehicles in otherlanes, objects that are not vehicles,or shadows. These alerts are normaloperation and the vehicle does notneed service.

Cleaning the System

If the FCA system does not seem tooperate properly, this may correct theissue:

. Clean the outside of thewindshield in front of the rearviewmirror.

. Clean the entire front of thevehicle.

. Clean the headlamps.

Forward AutomaticBraking (FAB)If the vehicle has Forward CollisionAlert (FCA), it also has FAB, whichincludes Intelligent Brake Assist (IBA).When the system detects a vehicleahead in your path that is traveling inthe same direction that you may beabout to crash into, it can provide aboost to braking or automaticallybrake the vehicle. This can help avoidor lessen the severity of crashes whendriving in a forward gear. Dependingon the situation, the vehicle mayautomatically brake moderately orhard. This forward automatic braking

can only occur if a vehicle is detected.This is shown by the FCA vehicleahead indicator being lit. See ForwardCollision Alert (FCA) System 0 277.

The system works when driving in aforward gear between 8 km/h (5 mph)and 80 km/h (50 mph), or on vehicleswith Adaptive Cruise Control (ACC),above 4 km/h (2 mph). It can detectvehicles up to approximately 60 m(197 ft).

{ Warning

FAB is an emergency crashpreparation feature and is notdesigned to avoid crashes. Do notrely on FAB to brake the vehicle.FAB will not brake outside of itsoperating speed range and onlyresponds to detected vehicles.

FAB may not:

. Detect a vehicle ahead onwinding or hilly roads.

(Continued)

Warning (Continued)

. Detect all vehicles, especiallyvehicles with a trailer,tractors, muddy vehicles, etc.

. Detect a vehicle whenweather limits visibility, suchas in fog, rain, or snow.

. Detect a vehicle ahead if it ispartially blocked bypedestrians or other objects.

Complete attention is alwaysrequired while driving, and youshould be ready to take action andapply the brakes and/or steer thevehicle to avoid crashes.

FAB may slow the vehicle to acomplete stop to try to avoid apotential crash. If this happens, FABmay engage the Electric Parking Brake(EPB) to hold the vehicle at a stop.Release the EPB or firmly press theaccelerator pedal.

{ Warning

FAB may automatically brake thevehicle suddenly in situationswhere it is unexpected andundesired. It could respond to aturning vehicle ahead, guardrails,signs, and other non-movingobjects. To override FAB, firmlypress the accelerator pedal, if it issafe to do so.

Intelligent Brake Assist (IBA)

IBA may activate when the brakepedal is applied quickly by providing aboost to braking based on the speedof approach and distance to a vehicleahead.

Minor brake pedal pulsations or pedalmovement during this time is normaland the brake pedal should continueto be applied as needed. IBA willautomatically disengage only whenthe brake pedal is released.

The camera must also be aligned towork correctly. If the camera needsadjustment, see your dealer. Do notattempt to adjust the camera yourself.

Side Blind ZoneAlert (SBZA)If equipped, the SBZA system is alane-changing aid that assists driverswith avoiding crashes that occur withmoving vehicles in the side blind zone(or spot) areas. When the vehicle is ina forward gear, the left or right sidemirror display will light up if a movingvehicle is detected in that blind zone.If the turn signal is activated and avehicle is also detected on the sameside, the display will flash as an extrawarning not to change lanes. Sincethis system is part of the Lane ChangeAlert (LCA) system, read the entireLCA section before using this feature.

Lane Change Alert (LCA)If equipped, the LCA system is alane-changing aid that assists driverswith avoiding lane change crashesthat occur with moving vehicles in theside blind zone (or spot) areas or withvehicles rapidly approaching theseareas from behind. The LCA warningdisplay will light up in thecorresponding outside side mirror andwill flash if the turn signal is on.

{ Warning

LCA does not alert the driver tovehicles outside of the systemdetection zones, pedestrians,bicyclists, or animals. It may notprovide alerts when changing lanesunder all driving conditions. Failureto use proper care when changinglanes may result in injury, death,or vehicle damage. Before making alane change, always check mirrors,glance over your shoulder, and usethe turn signals.

LCA Detection Zones

1. SBZA Detection Zone2. LCA Detection Zone

The LCA sensor covers a zone ofapproximately one lane over fromboth sides of the vehicle, or 3.5 m(11 ft). The height of the zone isapproximately between 0.5 m (1.5 ft)and 2 m (6 ft) off the ground. The SideBlind Zone Alert (SBZA) warning areastarts at approximately the middle ofthe vehicle and goes back 5 m (16 ft).Drivers are also warned of vehiclesrapidly approaching from up to 70 m(230 ft) behind the vehicle.

DRIVING AND OPERATING 287

How the System Works

The LCA symbol lights up in the sidemirrors when the system detects amoving vehicle in the next lane overthat is in the side blind zone orrapidly approaching that zone frombehind. A lit LCA symbol indicates itmay be unsafe to change lanes. Beforemaking a lane change, check the LCAdisplay, check mirrors, glance overyour shoulder, and use the turnsignals.

Left Side MirrorDisplay

Right Side MirrorDisplay

When the vehicle is started, bothoutside mirror LCA displays willbriefly come on to indicate the systemis operating. When the vehicle is in aforward gear, the left or right sidemirror display will light up if a movingvehicle is detected in the next laneover in that blind zone or rapidlyapproaching that zone. If the turn

signal is activated in the samedirection as a detected vehicle, thisdisplay will flash as an extra warningnot to change lanes.

LCA can be disabled. See “Collision/Detection Systems” under VehiclePersonalization 0 171. If LCA isdisabled by the driver, the LCA mirrordisplays will not light up.

When the System Does NotSeem to Work Properly

The LCA system requires some drivingfor the system to calibrate tomaximum performance. Thiscalibration may occur more quickly ifthe vehicle is driving on a straighthighway road with traffic and roadsideobjects (e.g., guardrails, barriers).

LCA displays may not come on whenpassing a vehicle quickly, for astopped vehicle, or when towing atrailer. The LCA detection zones thatextend back from the side of thevehicle do not move further backwhen a trailer is towed. Use cautionwhile changing lanes when towing atrailer. LCA may alert to objectsattached to the vehicle, such as a

trailer, bicycle, or object extending outto either side of the vehicle. Attachedobjects may also interfere with thedetection of vehicles. This is normalsystem operation; the vehicle does notneed service.

LCA may not always alert the driver tovehicles in the next lane over,especially in wet conditions or whendriving on sharp curves. The systemdoes not need to be serviced. Thesystem may light up due to guardrails,signs, trees, shrubs, and othernon-moving objects. This is normalsystem operation; the vehicle does notneed service.

LCA may not operate when the LCAsensors in the left or right corners ofthe rear bumper are covered withmud, dirt, snow, ice, or slush, or inheavy rainstorms. For cleaninginstructions, see "Washing theVehicle" under Exterior Care 0 404.If the DIC still displays the systemunavailable message after cleaningboth sides of the vehicle toward therear corners of the vehicle, see yourdealer.

Radio Frequency Information

See Radio Frequency Statement 0 443.

Lane DepartureWarning (LDW)If equipped, LDW may help avoidcrashes due to unintentional lanedepartures. It may provide a warningif the vehicle is crossing a detectedlane marking without using a turnsignal in the lane departure direction.Since this system is part of the LaneKeep Assist (LKA) system, read theentire LKA section before using thisfeature.

Lane Keep Assist (LKA)If equipped, LKA may help avoidcrashes due to unintentional lanedepartures. It may assist by gentlyturning the steering wheel if thevehicle approaches a detected lanemarking without using a turn signal inthat direction. It may also provide aLane Departure Warning (LDW)system alert as the lane marking iscrossed. The LKA system will notassist or provide an LDW alert if itdetects that you are actively steering.Override LKA by turning the steeringwheel. LKA uses a camera to detectlane markings between 60 km/h (37mph) and 180 km/h (112 mph).

{ Warning

The LKA system does notcontinuously steer the vehicle.It may not keep the vehicle in thelane or give a Lane DepartureWarning (LDW) alert, even if a lanemarking is detected.

Warning (Continued)

The LKA and LDW systemsmay not:

. Provide an alert or enoughsteering assist to avoid a lanedeparture or crash.

. Detect lane markings underpoor weather or visibilityconditions. This can occur ifthe windshield or headlampsare blocked by dirt, snow,or ice, if they are not inproper condition, or if the sunshines directly into thecamera.

. Detect road edges.

. Detect lanes on winding orhilly roads.

If LKA only detects lane markingson one side of the road, it will onlyassist or provide an LDW alertwhen approaching the lane on theside where it has detected a lanemarking. Even with LKA and LDW,

{ Warning

Using LKA while towing a trailer oron slippery roads could cause lossof control of the vehicle and acrash. Turn the system off.

How the System Works

The LKA camera sensor is on thewindshield ahead of the rearviewmirror.

To turn LKA on and off, pressAon the center stack.

LKA Indicator Light

When on, the LKA indicator is green ifLKA is available to assist and provideLDW alerts. It may assist by gentlyturning the steering wheel and displayamber if the vehicle approaches adetected lane marking without using aturn signal in that direction. It mayalso provide an LDW alert by flashingamber as the lane marking is crossed.Additionally, there may be threebeeps, or the driver seat may pulsethree times, on the right or left,depending on the lane departuredirection.

Take Steering

The LKA system does notcontinuously steer the vehicle. If LKAdoes not detect active driver steering,an alert, chime, or DIC message maybe provided. Steer the vehicle todismiss.

When the System Does NotSeem to Work Properly

The system performance may beaffected by:

. Close vehicles ahead.

. Sudden lighting changes, such aswhen driving through tunnels.

. Banked roads.

. Roads with poor lane markings,such as two-lane roads.

If the LKA system is not functioningproperly when lane markings areclearly visible, cleaning the windshieldmay help.

DRIVING AND OPERATING 311

{ Warning

When towing a trailer, exhaustgases may collect at the rear of thevehicle and enter if the liftgate,trunk/hatch, or rear-most windowis open.

When towing a trailer:

. Do not drive with the liftgate,trunk/hatch, or rear-mostwindow open.

. Fully open the air outlets onor under the instrumentpanel.

. Also adjust the climatecontrol system to a settingthat brings in only outside air.See “Climate Control Systems”in the Index.

For more information about carbonmonoxide, see Engine Exhaust0 232.

Towing a trailer requires a certainamount of experience. Thecombination you are driving is longer

and not as responsive as the vehicleitself. Get acquainted with thehandling and braking of the rig beforesetting out for the open road.

Before starting, check all trailer hitchparts and attachments, safety chains,electrical connectors, lamps, tires, andmirrors. If the trailer has electricbrakes, start the combination movingand then apply the trailer brakecontroller by hand to be sure thebrakes work.

During the trip, check occasionally tobe sure that the load is secure and thelamps and any trailer brakesstill work.

Following Distance

Stay at least twice as far behind thevehicle ahead as you would whendriving the vehicle without a trailer.This can help to avoid heavy brakingand sudden turns.

Passing

More passing distance is needed whentowing a trailer. The combination willnot accelerate as quickly and is longer

so it is necessary to go much fartherbeyond the passed vehicle beforereturning to the lane.

Backing Up

Hold the bottom of the steering wheelwith one hand. To move the trailer tothe left, move that hand to the left. Tomove the trailer to the right, moveyour hand to the right. Always backup slowly and, if possible, havesomeone guide you.

Making Turns

Caution

Making very sharp turns whiletrailering could cause the trailer tocome in contact with the vehicle.The vehicle could be damaged.Avoid making very sharp turnswhile trailering.

When turning with a trailer, makewider turns than normal. Do this sothe trailer will not strike soft

Page 313: C M Y CM MY CY CMY K - cadillac.com · Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) - 2018 - CRC - 3/1/18 INTRODUCTION 3 {WarningWarning indicates a hazard that

shoulders, curbs, road signs, trees,or other objects. Avoid jerky or suddenmaneuvers. Signal well in advance.

If the trailer turn signal bulbs burnout, the arrows on the instrumentcluster will still flash for turns. It isimportant to check occasionally to besure the trailer bulbs are still working.

Driving on Grades

Reduce speed and shift to a lower gearbefore starting down a long or steepdowngrade. If the transmission is notshifted down, the brakes might get hotand no longer work well.

Vehicles can tow in D (Drive). Shiftthe transmission to a lower gear if thetransmission shifts too often underheavy loads and/or hilly conditions.

When towing at high altitude on steepuphill grades, consider the following:Engine coolant will boil at a lowertemperature than at normal altitudes.If the engine is turned off immediatelyafter towing at high altitude on steepuphill grades, the vehicle may showsigns similar to engine overheating. Toavoid this, let the engine run whileparked, preferably on level ground,

with the automatic transmission inP (Park) for a few minutes beforeturning the engine off. If the overheatwarning comes on, see EngineOverheating 0 341.

Parking on Hills

{ Warning

Parking the vehicle on a hill withthe trailer attached can bedangerous. If something goeswrong, the rig could start to move.People can be injured, and both thevehicle and the trailer can bedamaged. When possible, alwayspark the rig on a flat surface.

If parking the rig on a hill:

1. Press the brake pedal, but do notshift into P (Park) yet. Turn thewheels into the curb if facingdownhill or into traffic if facinguphill.

2. Have someone place chocksunder the trailer wheels.

3. When the wheel chocks are inplace, release the regular brakesuntil the chocks absorb the load.

4. Reapply the brake pedal. Thenapply the parking brake and shiftinto P (Park).

5. Release the brake pedal.

Leaving After Parking on a Hill

1. Apply and hold the brake pedal.

2. Start the engine.

3. Shift into a gear.

4. Release the parking brake.

5. Let up on the brake pedal.

6. Drive slowly until the trailer isclear of the chocks.

7. Stop and have someone pick upand store the chocks.

Maintenance when TrailerTowing

The vehicle needs service more oftenwhen pulling a trailer. . Things thatare especially important in traileroperation are automatic transmissionfluid, engine oil, axle lubricant, belts,

Page 314: C M Y CM MY CY CMY K - cadillac.com · Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) - 2018 - CRC - 3/1/18 INTRODUCTION 3 {WarningWarning indicates a hazard that

DRIVING AND OPERATING 313

cooling system, and brake system. It isa good idea to inspect these beforeand during the trip.

Check periodically to see that all hitchnuts and bolts are tight.

Trailer Towing(PLUG-IN Only)The vehicle is neither designed norintended to tow a trailer.

Trailer Towing(Gasoline Only)Before pulling a trailer, threeimportant considerations have to dowith weight:

. Weight of the trailer.

. Weight of the trailer tongue.

. Total weight on your vehicle'stires.

Weight of the Trailer

How heavy can a trailer safely be?

It should never weigh more than454 kg (1,000 lb). But even that can betoo heavy.

Safe trailering requires monitoring theweight, speed, altitude, road grades,outside temperature, the dimensionsof the front of the trailer, and howfrequently the vehicle is used to pull atrailer. Take into consideration anyspecial equipment on the vehicle, andthe amount of tongue weight thevehicle can carry. See “Weight of theTrailer Tongue” later in this sectionfor more information.

Trailer weight rating (TWR) iscalculated assuming the tow vehiclehas the driver, a front seat passenger,and all required trailering equipment.Weight of additional optionalequipment, passengers, and cargo inthe tow vehicle must be subtractedfrom the trailer weight rating.

Ask your dealer for traileringinformation or advice, or write us atour Customer Assistance Offices. SeeCustomer Assistance Offices 0 435.

Weight of the Trailer Tongue

The tongue weight load (1) of anytrailer is very important because it isalso part of the vehicle weight. TheGross Vehicle Weight (GVW) includes

the curb weight of the vehicle, anycargo carried in it, and the people whowill be riding in the vehicle, as well astrailer tongue weight. Vehicle options,equipment, passengers, and cargo inthe vehicle reduce the amount oftongue weight the vehicle can carry,which will also reduce the trailerweight the vehicle can tow. See VehicleLoad Limits 0 215.

In general, trailer tongue weight (1)should be 10% of the loaded trailerweight (2). Some specific trailer types,such as boat trailers, fall outside ofthis range. Refer to the trailer owner’smanual for the recommended trailer

Page 315: C M Y CM MY CY CMY K - cadillac.com · Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) - 2018 - CRC - 3/1/18 INTRODUCTION 3 {WarningWarning indicates a hazard that

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) -2018 - CRC - 3/1/18

314 DRIVING AND OPERATING

tongue weight. In all cases, do notexceed the maximum loads for thevehicle series and hitch type.

After loading the trailer, weigh thetrailer and then the tongue,separately, to see if the weights areproper. If they are not, adjustmentsmight be made by moving some itemsaround in the trailer.

Total Weight on Your Vehicle'sTires

Be sure the vehicle's tires are inflatedto the upper limit for cold tires. Thesenumbers can be found on the Tire andLoading Information label. See VehicleLoad Limits 0 215. Make sure not to goover the GVW limit for the vehicle,including the weight of the trailertongue.

Towing Equipment

Hitches

Use the correct hitch equipment. Seeyour dealer or a hitch dealer forassistance.

. The rear bumper on the vehicle isnot intended for hitches. Do notattach rental hitches or otherbumper-type hitches to it. Useonly a frame-mounted hitch thatdoes not attach to the bumper.

. The frame mounted hitch must becompatible with aluminum.

. Will any holes be made in thebody of the vehicle when thetrailer hitch is installed? If so, sealthe holes when the hitch isremoved. If the holes are notsealed, dirt, water, and deadlycarbon monoxide (CO) from theexhaust can get into the vehicle.See Engine Exhaust 0 232.

Safety Chains

Always attach chains between thevehicle and the trailer. Cross the safetychains under the tongue of the trailerto help prevent the tongue fromcontacting the road if it becomesseparated from the hitch. Leaveenough slack so the rig can turn.Never allow safety chains to drag onthe ground.

Trailer Brakes

Does the trailer have its own brakes?State and local regulations may alsorequire the trailer to have its ownbraking system if loaded above acertain threshold. These requirementsvary from state to state.

Be sure to read and follow theinstructions for the trailer brakes sothey are installed, adjusted, andmaintained properly.

Because the vehicle has antilockbrakes, do not tap into the vehicle'sbrake system. If this is done, bothbrake systems will not work well orat all.

Engine OilTo ensure proper engine performanceand long life, careful attention mustbe paid to engine oil. Following thesesimple, but important steps will helpprotect your investment:

. Use engine oil approved to theproper specification and of theproper viscosity grade. See“Selecting the Right Engine Oil” inthis section.

. Check the engine oil level regularlyand maintain the proper oil level.See “Checking Engine Oil” and“When to Add Engine Oil” later inthis section.

. Change the engine oil at theappropriate time. See Engine OilLife System 0 329.

. Always dispose of engine oilproperly. See “What to Do withUsed Oil” in this section.

Checking Engine Oil

Check the engine oil level regularly,every 650 km (400 mi), especially priorto a long trip. The engine oil dipstick

handle is a loop. See EngineCompartment Overview 0 320 for thelocation.

{ Warning

The engine oil dipstick handle maybe hot; it could burn you. Use atowel or glove to touch the dipstickhandle.

If a low oil Driver Information Center(DIC) message displays, check the oillevel.

Follow these guidelines:

. To get an accurate reading, parkthe vehicle on level ground. Checkthe engine oil level after theengine has been off for at leasttwo hours. Checking the engine oillevel on steep grades or too soonafter engine shutoff can result inincorrect readings. Accuracyimproves when checking a coldengine prior to starting. Removethe dipstick and check the level.

328 VEHICLE CARE. If unable to wait two hours, the

engine must be off for at least15 minutes if the engine is warm,or at least 30 minutes if theengine is not warm. Pull out thedipstick, wipe it with a clean papertowel or cloth, then push it backin all the way. Remove it again,keeping the tip down, and checkthe level.

When to Add Engine Oil

2.0L L4 Engine

3.0L and 3.6L V6 Engines

If the oil is below the cross-hatchedarea at the tip of the dipstick and theengine has been off for at least15 minutes, add 1 L (1 qt) of therecommended oil and then recheckthe level. See “Selecting the RightEngine Oil” later in this section for anexplanation of what kind of oil to use.For engine oil crankcase capacity, seeCapacities and Specifications 0 429.

Caution

Do not add too much oil. Oil levelsabove or below the acceptableoperating range shown on thedipstick are harmful to the engine.If you find that you have an oillevel above the operating range, i.e.,the engine has so much oil that theoil level gets above thecross-hatched area that shows theproper operating range, the enginecould be damaged. You shoulddrain out the excess oil or limitdriving of the vehicle and seek aservice professional to remove theexcess amount of oil.

See Engine Compartment Overview0 320 for the location of the engine oilfill cap.

Add enough oil to put the levelsomewhere in the proper operatingrange. Push the dipstick all the wayback in when through.

Selecting the Right Engine Oil

Selecting the right engine oil dependson both the proper oil specificationand viscosity grade. See RecommendedFluids and Lubricants 0 424.

Specification

Ask for and use full synthetic engineoils that meet the dexos1specification. Engine oils that havebeen approved by GM as meeting thedexos1 specification are marked withthe dexos1 approved logo. Seewww.gmdexos.com.

VEHICLE CARE 329

Caution

Failure to use the recommendedengine oil or equivalent can resultin engine damage not covered bythe vehicle warranty.

Viscosity Grade

Use SAE 5W-30 viscosity gradeengine oil.

Cold Temperature Operation: In anarea of extreme cold, where thetemperature falls below −29 °C(−20 °F), an SAE 0W-30 oil may beused. An oil of this viscosity grade willprovide easier cold starting for theengine at extremely low temperatures.When selecting an oil of theappropriate viscosity grade, it isrecommended to select an oil of thecorrect specification. See“Specification” earlier in this section.

Engine Oil Additives/Engine OilFlushes

Do not add anything to the oil. Therecommended oils meeting the dexos1specification are all that is needed forgood performance and engineprotection.

Engine oil system flushes are notrecommended and could cause enginedamage not covered by the vehiclewarranty.

What to Do with Used Oil

Used engine oil contains certainelements that can be unhealthy foryour skin and could even causecancer. Do not let used oil stay onyour skin for very long. Clean yourskin and nails with soap and water,or a good hand cleaner. Wash orproperly dispose of clothing or ragscontaining used engine oil. See themanufacturer's warnings about theuse and disposal of oil products.

Used oil can be a threat to theenvironment. If you change your ownoil, be sure to drain all the oil fromthe filter before disposal. Never

dispose of oil by putting it in the trashor pouring it on the ground, intosewers, or into streams or bodies ofwater. Recycle it by taking it to a placethat collects used oil.

Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer systemthat indicates when to change theengine oil and filter. This is based on acombination of factors which includeengine revolutions, enginetemperature, and miles driven. Basedon driving conditions, the mileage atwhich an oil change is indicated canvary considerably. For the oil lifesystem to work properly, the systemmust be reset every time the oil ischanged.

When the system has calculated thatoil life has been diminished, itindicates that an oil change isnecessary. A CHANGE ENGINE OILSOON message comes on. Change theoil as soon as possible within the next1 000 km (600 mi). It is possible that,if driving under the best conditions,

If the warning continues, pull over,stop, and park the vehicle right away.

If there is no sign of steam, idle theengine for three minutes while parked.If the warning is still displayed, turnoff the engine until it cools down.

Washer Fluid

What to Use

When windshield washer fluid isneeded, be sure to read themanufacturer's instructions beforeuse. If operating the vehicle in an areawhere the temperature may fall belowfreezing, use a fluid that has sufficientprotection against freezing.

Adding Washer Fluid

Open the cap with the washer symbolon it. Add washer fluid until the tankis full. See Engine CompartmentOverview 0 320 for reservoir location.

Caution

. Do not use washer fluid thatcontains any type of waterrepellent coating. This cancause the wiper blades tochatter or skip.

. Do not use engine coolant(antifreeze) in the windshieldwasher. It can damage thewindshield washer systemand paint.

. Do not mix water withready-to-use washer fluid.Water can cause the solutionto freeze and damage thewasher fluid tank and otherparts of the washer system.

. When using concentratedwasher fluid, follow themanufacturer instructions foradding water.

. Fill the washer fluid tank onlythree-quarters full when it isvery cold. This allows forfluid expansion if freezing

BrakesDisc brake pads have built-in wearindicators that make a high-pitchedwarning sound when the brake padsare worn and new pads are needed.The sound can come and go or can beheard all the time when the vehicle ismoving, except when applying thebrake pedal firmly.

{ Warning

The brake wear warning soundmeans that soon the brakes will notwork well. That could lead to acrash. When the brake wearwarning sound is heard, have thevehicle serviced.

Caution

Continuing to drive with worn-outbrake pads could result in costlybrake repair.

Some driving conditions or climatescan cause a brake squeal when thebrakes are first applied or lightlyapplied. This does not meansomething is wrong with the brakes.

Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear andevenly tighten wheel nuts in theproper sequence to torquespecifications. See Capacities andSpecifications 0 429.

Brake pads should be replaced ascomplete sets.

Brake Pedal Travel

See your dealer if the brake pedal doesnot return to normal height, or ifthere is a rapid increase in pedaltravel. This could be a sign that brakeservice may be required.

Replacing Brake System Parts

Always replace brake system partswith new, approved replacement parts.If this is not done, the brakes may notwork properly. The brakingperformance expected can change inmany other ways if the wrongreplacement brake parts are installedor if parts are improperly installed.

Brake Fluid

The brake master cylinder reservoir isfilled with GM approved DOT 3 (forgasoline only vehicles) or DOT 4 (forPLUG-IN vehicles) brake fluid asindicated on the reservoir cap. SeeEngine Compartment Overview 0 320for the location of the reservoir.

344 VEHICLE CARE

Checking Brake Fluid

With the vehicle in P (Park) on a levelsurface, the brake fluid level should bebetween the minimum and maximummarks on the brake fluid reservoir.

There are only two reasons why thebrake fluid level in the reservoir maygo down:

. Normal brake lining wear. Whennew linings are installed, the fluidlevel goes back up.

. A fluid leak in the brake hydraulicsystem. Have the brake hydraulicsystem fixed. With a leak, thebrakes will not work well.

Always clean the brake fluid reservoircap and the area around the capbefore removing it.

Do not top off the brake fluid. Addingfluid does not correct a leak. If fluid isadded when the linings are worn,there will be too much fluid whennew brake linings are installed. Add orremove fluid, as necessary, only whenwork is done on the brake hydraulicsystem.

{ Warning

If too much brake fluid is added, itcan spill on the engine and burn,if the engine is hot enough. You orothers could be burned, and thevehicle could be damaged. Addbrake fluid only when work is doneon the brake hydraulic system.

When the brake fluid falls to a lowlevel, the brake warning light comeson. See Brake System Warning Light0 145.

Brake fluid absorbs water over timewhich degrades the effectiveness ofthe brake fluid. Replace brake fluid atthe specified intervals to preventincreased stopping distance. SeeMaintenance Schedule 0 415.

What to Add

Use only GM approved DOT 3 (forgasoline only vehicles) or DOT 4 (forPLUG-IN vehicles) brake fluid from aclean, sealed container. SeeRecommended Fluids and Lubricants0 424.

{ Warning

The wrong or contaminated brakefluid could result in damage to thebrake system. This could result inthe loss of braking leading to apossible injury. Always use theproper GM approved brake fluid.

Caution

If brake fluid is spilled on thevehicle's painted surfaces, the paintfinish can be damaged. Immediatelywash off any painted surface.

Electrical System OverloadThe vehicle has fuses and circuitbreakers to protect against anelectrical system overload.

When the current electrical load is tooheavy, the circuit breaker opens andcloses, protecting the circuit until thecurrent load returns to normal or theproblem is fixed. This greatly reducesthe chance of circuit overload and firecaused by electrical problems.

Fuses and circuit breakers protectpower devices in the vehicle.

Replace a bad fuse with a new one ofthe identical size and rating.

If there is a problem on the road anda fuse needs to be replaced, thesame amperage fuse can be borrowed.Choose some feature of the vehiclethat is not needed to use and replaceit as soon as possible.

Headlamp Wiring

An electrical overload may cause thelamps to go on and off, or in somecases to remain off. Have theheadlamp wiring checked right away ifthe lamps go on and off or remain off.

Windshield Wipers

If the wiper motor overheats due toheavy snow or ice, the windshieldwipers will stop. Wiper function isavailable immediately after the wiperswitch is set to off, and back to on.

To protect the wiper motor fromoverheating, the wipers may slowdown when the windshield is dry for along period of time. If a period of dryoperation, or little moisture, exceeds10 minutes, the wipers may switch tointermittent operation, and remainthere. When moisture is againdetected on the windshield, wiperoperation will return to the operatorselected speed.

Although the circuit is protected fromelectrical overload, overload due toheavy snow or ice may cause wiper

linkage damage. Always clear ice andheavy snow from the windshieldbefore using the windshield wipers.

If the overload is caused by anelectrical problem and not snow orice, be sure to get it fixed.

Fuses and Circuit BreakersThe wiring circuits in the vehicle areprotected from short circuits by acombination of fuses and circuitbreakers. This greatly reduces thechance of damage caused by electricalproblems.

{ Danger

Fuses and circuit breakers aremarked with their ampere rating.Do not exceed thespecified amperage rating whenreplacing fuses and circuit breakers.Use of an oversized fuse or circuitbreaker can result in a vehicle fire.You and others could be seriouslyinjured or killed.

To check a fuse, look at thesilver-colored band inside the fuse.If the band is broken or melted,replace the fuse. Be sure to replace abad fuse with a new one of theidentical size and rating.

Fuses of the same amperage can betemporarily borrowed from anotherfuse location, if a fuse goes out.Replace the fuse as soon as possible.

TiresEvery new GM vehicle hashigh-quality tires made by aleading tire manufacturer. See thewarranty manual for informationregarding the tire warranty andwhere to get service. Foradditional information refer to thetire manufacturer.

{ Warning

. Poorly maintained andimproperly used tires aredangerous.

. Overloading the tires cancause overheating as aresult of too much flexing.There could be a blowoutand a serious crash. SeeVehicle Load Limits 0 215.

(Continued)

Warning (Continued)

. Underinflated tires posethe same danger asoverloaded tires. Theresulting crash could causeserious injury. Check alltires frequently tomaintain therecommended pressure.Tire pressure should bechecked when the tiresare cold.

. Overinflated tires are morelikely to be cut, punctured,or broken by a suddenimpact — such as whenhitting a pothole. Keeptires at the recommendedpressure.

. Worn or old tires cancause a crash. If the treadis badly worn,replace them.

Warning (Continued)

. Replace any tires that havebeen damaged by impactswith potholes, curbs, etc.

. Improperly repaired tirescan cause a crash. Onlythe dealer or an authorizedtire service center shouldrepair, replace, dismount,and mount the tires.

. Do not spin the tires inexcess of 56 km/h(35 mph) on slipperysurfaces such as snow,mud, ice, etc. Excessivespinning may cause thetires to explode.

See Tire Pressure for High-SpeedOperation 0 371 for inflationpressure adjustment forhigh-speed driving.

All-Season TiresThis vehicle may come with all-seasontires. These tires are designed toprovide good overall performance onmost road surfaces and weatherconditions. Original equipment tiresdesigned to GM's specific tireperformance criteria have a TPCspecification code molded onto thesidewall. Original equipmentall-season tires can be identified bythe last two characters of this TPCcode, which will be “MS.”

Consider installing winter tires on thevehicle if frequent driving on snow orice-covered roads is expected.All-season tires provide adequateperformance for most winter drivingconditions, but they may not offer thesame level of traction or performanceas winter tires on snow or ice-coveredroads. See Winter Tires 0 363.

Winter TiresThis vehicle was not originallyequipped with winter tires. Wintertires are designed for increasedtraction on snow and ice-covered

roads. Consider installing winter tireson the vehicle if frequent driving onice or snow covered roads is expected.See your dealer for details regardingwinter tire availability and proper tireselection. Also, see Buying New Tires0 378.

With winter tires, there may bedecreased dry road traction, increasedroad noise, and shorter tread life.After changing to winter tires, be alertfor changes in vehicle handling andbraking.

If using winter tires:

. Use tires of the same brand andtread type on all four wheelpositions.

. Use only radial ply tires of thesame size, load range, and speedrating as the original equipmenttires.

Winter tires with the same speedrating as the original equipment tiresmay not be available for H, V, W, Y,and ZR speed rated tires. If wintertires with a lower speed rating arechosen, never exceed the tire'smaximum speed capability.

Low-Profile TiresIf the vehicle has 245/45R19,245/40R20, or 245/40ZR20 sizetires, they are classified aslow-profile tires.

Caution

Low-profile tires are moresusceptible to damage from roadhazards or curb impact thanstandard profile tires. Tire and/orwheel assembly damage can occurwhen coming into contact withroad hazards like potholes, or sharpedged objects, or when sliding intoa curb. The warranty does not coverthis type of damage. Keep tires setto the correct inflation pressure andwhen possible, avoid contact withcurbs, potholes, and other roadhazards.

Summer TiresThis vehicle may come with highperformance summer tires. These tireshave a special tread and compoundthat are optimized for maximum dryand wet road performance. Thisspecial tread and compound will havedecreased performance in coldclimates, and on ice and snow. It isrecommended that winter tires beinstalled on the vehicle if frequentdriving at temperatures belowapproximately 5 °C (40 °F) or on ice orsnow covered roads is expected. SeeWinter Tires 0 363.

Caution

High performance summer tireshave rubber compounds that loseflexibility and may develop surfacecracks in the tread area attemperatures below −7 °C (20 °F).Always store high performancesummer tires indoors and attemperatures above −7 °C (20 °F)when not in use. If the tires have

370 VEHICLE CARE

Caution

Neither tire underinflation noroverinflation is good.Underinflated tires, or tires thatdo not have enough air, canresult in:

. Tire overloading andoverheating which couldlead to a blowout.

. Premature orirregular wear.

. Poor handling.

. Reduced fuel economy.

Overinflated tires, or tires thathave too much air, can result in:

. Unusual wear.

. Poor handling.

. Rough ride.

. Needless damage fromroad hazards.

The Tire and Loading Informationlabel on the vehicle indicates theoriginal equipment tires and thecorrect cold tire inflationpressures. The recommendedpressure is the minimum airpressure needed to support thevehicle's maximum load carryingcapacity. See Vehicle Load Limits0 215.

How the vehicle is loaded affectsvehicle handling and ride comfort.Never load the vehicle with moreweight than it was designed tocarry.

When to Check

Check the tires once a month ormore. Do not forget the compactspare, if the vehicle has one. Thecold compact spare tire pressureshould be at 420 kPa (60 psi). SeeCompact Spare Tire 0 396.

How to Check

Use a good quality pocket-typegauge to check tire pressure.Proper tire inflation cannot bedetermined by looking at the tire.Check the tire inflation pressurewhen the tires are cold, meaningthe vehicle has not been driven forat least three hours or no morethan 1.6 km (1 mi).

Remove the valve cap from thetire valve stem. Press the tiregauge firmly onto the valve to geta pressure measurement. If thecold tire inflation pressurematches the recommendedpressure on the Tire and LoadingInformation label, no furtheradjustment is necessary. If theinflation pressure is low, add airuntil the recommended pressure isreached. If the inflation pressureis high, press on the metal stem inthe center of the tire valve torelease air.

Each tire, including the spare (ifprovided), should be checked monthlywhen cold and inflated to theinflation pressure recommended bythe vehicle manufacturer on thevehicle placard or tire inflationpressure label. (If your vehicle hastires of a different size than the sizeindicated on the vehicle placard or tireinflation pressure label, you shoulddetermine the proper tire inflationpressure for those tires.)

As an added safety feature, yourvehicle has been equipped with a tirepressure monitoring system (TPMS)that illuminates a low tire pressuretelltale when one or more of your tiresis significantly under-inflated.

Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate them tothe proper pressure. Driving on asignificantly under-inflated tire causesthe tire to overheat and can lead totire failure. Under-inflation alsoreduces fuel efficiency and tire treadlife, and may affect the vehicle'shandling and stopping ability.

Please note that the TPMS is not asubstitute for proper tire maintenance,and it is the driver's responsibility tomaintain correct tire pressure, even ifunder-inflation has not reached thelevel to trigger illumination of theTPMS low tire pressure telltale.

Your vehicle has also been equippedwith a TPMS malfunction indicator toindicate when the system is notoperating properly. The TPMSmalfunction indicator is combinedwith the low tire pressure telltale.When the system detects amalfunction, the telltale will flash forapproximately one minute and thenremain continuously illuminated. Thissequence will continue uponsubsequent vehicle start-ups as longas the malfunction exists.

When the malfunction indicator isilluminated, the system may not beable to detect or signal low tirepressure as intended. TPMSmalfunctions may occur for a varietyof reasons, including the installationof replacement or alternate tires orwheels on the vehicle that prevent theTPMS from functioning properly.

Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allow theTPMS to continue to functionproperly.

See Tire Pressure Monitor Operation0 372.

See Radio Frequency Statement 0 443.

Tire Pressure MonitorOperationThis vehicle may have a Tire PressureMonitor System (TPMS). The TPMS isdesigned to warn the driver when alow tire pressure condition exists.TPMS sensors are mounted onto eachtire and wheel assembly, excluding thespare tire and wheel assembly. TheTPMS sensors monitor the airpressure in the tires and transmit thetire pressure readings to a receiverlocated in the vehicle.

When a low tire pressure condition isdetected, the TPMS illuminates thelow tire pressure warning light on theinstrument cluster. If the warninglight comes on, stop as soon aspossible and inflate the tires to therecommended pressure shown on theTire and Loading Information label.See Vehicle Load Limits 0 215.

A message to check the pressure in aspecific tire displays in the DriverInformation Center (DIC). The low tirepressure warning light and the DICwarning message come on at eachignition cycle until the tires areinflated to the correct inflationpressure. Using the DIC, tire pressurelevels can be viewed. For additionalinformation and details about the DICoperation and displays see DriverInformation Center (DIC) 0 163.

The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven. Thiscould be an early indicator that the airpressure is getting low and needs tobe inflated to the proper pressure.

A Tire and Loading Information label,attached to your vehicle, shows thesize of the original equipment tiresand the correct inflation pressure forthe tires when they are cold. SeeVehicle Load Limits 0 215, for anexample of the Tire and LoadingInformation label and its location.Also see Tire Pressure 0 369.

The TPMS can warn about a low tirepressure condition but it does notreplace normal tire maintenance. SeeTire Inspection 0 375, Tire Rotation0 376 and Tires 0 362.

The malfunction light and DICwarning message come on at eachignition cycle until the problem iscorrected. Some of the conditions thatcan cause these to come on are:

. One of the road tires has beenreplaced with the spare tire. Thespare tire does not have a TPMSsensor. The malfunction light andDIC message should go off afterthe road tire is replaced and thesensor matching process isperformed successfully. See “TPMSSensor Matching Process” later inthis section.

. The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tires. The malfunctionlight and the DIC message shouldgo off after successfullycompleting the sensor matchingprocess. See "TPMS SensorMatching Process" later in thissection.

. One or more TPMS sensors aremissing or damaged. Themalfunction light and the DICmessage should go off when the

TPMS sensors are installed andthe sensor matching process isperformed successfully. See yourdealer for service.

. Replacement tires or wheels donot match the original equipmenttires or wheels. Tires and wheelsother than those recommendedcould prevent the TPMS fromfunctioning properly. See BuyingNew Tires 0 378.

. Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.

If the TPMS is not functioningproperly it cannot detect or signal alow tire pressure condition. See yourdealer for service if the TPMSmalfunction light and DIC messagecomes on and stays on.

TPMS Sensor Matching Process

Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to a newtire/wheel position after rotating thevehicle’s tires or replacing one or more

of the TPMS sensors. The TPMSsensor matching process should alsobe performed after replacing a sparetire with a road tire containing theTPMS sensor. The malfunction lightand the DIC message should go off atthe next ignition cycle. The sensorsare matched to the tire/wheelpositions, using a TPMS relearn tool,in the following order: driver sidefront tire, passenger side front tire,passenger side rear tire, and driverside rear. See your dealer for service orto purchase a relearn tool. A TPMSrelearn tool can also be purchased.See Tire Pressure Monitor SensorActivation Tool atwww.gmtoolsandequipment.com orcall 1-800-GM TOOLS(1-800-468-6657).

There are two minutes to match thefirst tire/wheel position, andfive minutes overall to match all fourtire/wheel positions. If it takes longer,the matching process stops and mustbe restarted.

The TPMS sensor matching process is:

1. Set the parking brake.

6. Start with the driver sidefront tire.

7. Place the relearn tool against thetire sidewall, near the valve stem.Then press the button to activate

the TPMS sensor. A horn chirpconfirms that the sensoridentification code has beenmatched to this tire and wheelposition.

8. Proceed to the passenger sidefront tire, and repeat Step 7.

9. Proceed to the passenger siderear tire, and repeat Step 7.

10. Proceed to the driver side reartire, and repeat Step 7. The hornsounds two times to indicate thesensor identification code hasbeen matched to the driver siderear tire, and the TPMS sensormatching process is no longeractive. The TIRE LEARNINGACTIVE message on the DICdisplay screen goes off.

11. Turn the vehicle off.

12. Set all four tires to therecommended air pressure levelas indicated on the Tire andLoading Information label.

Tire InspectionWe recommend that the tires,including the spare tire, if thevehicle has one, be inspected forsigns of wear or damage at leastonce a month.

Replace the tire if:

. The indicators at three or moreplaces around the tire canbe seen.

. There is cord or fabric showingthrough the tire's rubber.

. The tread or sidewall iscracked, cut, or snagged deepenough to show cord or fabric.

. The tire has a bump, bulge,or split.

. The tire has a puncture, cut,or other damage that cannotbe repaired well because of thesize or location of the damage.

Tire RotationTires should be rotated every12 000 km/7,500 mi. SeeMaintenance Schedule 0 415.

Tires are rotated to achieve auniform wear for all tires. The firstrotation is the most important.

Anytime unusual wear is noticed,rotate the tires as soon aspossible, check for proper tireinflation pressure, and check fordamaged tires or wheels. If theunusual wear continues after therotation, check the wheelalignment. See When It Is Time forNew Tires 0 377 and WheelReplacement 0 381.

Use this rotation pattern if thevehicle has different size tires onthe front and rear.

Different tire sizes should not berotated front to rear.

Use this rotation pattern whenrotating tires of the same sizeinstalled on all four wheelpositions.

If the vehicle has a compact sparetire, do not include it in the tirerotation.

Adjust the front and rear tires tothe recommended inflationpressure on the Tire and LoadingInformation label after the tireshave been rotated. See TirePressure 0 369 and Vehicle LoadLimits 0 215.

Reset the Tire Pressure MonitorSystem. See Tire Pressure MonitorOperation 0 372.

Check that all wheel nuts areproperly tightened. See “WheelNut Torque” under Capacities andSpecifications 0 429.

{ Warning

Rust or dirt on a wheel, or on theparts to which it is fastened, canmake wheel nuts become looseafter time. The wheel could comeoff and cause an accident. Whenchanging a wheel, remove any rustor dirt from places where the wheelattaches to the vehicle. In anemergency, a cloth or a paper towelcan be used; however, use a scraperor wire brush later to remove allrust or dirt.

Lightly coat the center of thewheel hub with wheel bearinggrease after a wheel change or tirerotation to prevent corrosion or

rust build-up. Do not get greaseon the flat wheel mountingsurface or on the wheel nuts orbolts.

When It Is Time for NewTiresFactors such as maintenance,temperatures, driving speeds, vehicleloading, and road conditions affect thewear rate of the tires.

Treadwear indicators are one way totell when it is time for new tires.Treadwear indicators appear when thetires have only 1.6 mm (1/16 in) orless of tread remaining. See TireInspection 0 375 and Tire Rotation0 376.

The rubber in tires ages over time.This also applies to the spare tire,if the vehicle has one, even if it isnever used. Multiple factors includingtemperatures, loading conditions, andinflation pressure maintenance affecthow fast aging takes place. GMrecommends that tires, including thespare if equipped, be replaced after sixyears, regardless of tread wear. Thetire manufacture date is the last fourdigits of the DOT Tire IdentificationNumber (TIN) which is molded intoone side of the tire sidewall. The firsttwo digits represent the week (01–52)and the last two digits, the year. Forexample, the third week of the year2010 would have a four-digit DOTdate of 0310.

Vehicle Storage

Tires age when stored normallymounted on a parked vehicle. Park avehicle that will be stored for at leasta month in a cool, dry, clean areaaway from direct sunlight to slowaging. This area should be free ofgrease, gasoline, or other substancesthat can deteriorate rubber.

Parking for an extended period cancause flat spots on the tires that mayresult in vibrations while driving.When storing a vehicle for at least amonth, remove the tires or raise thevehicle to reduce the weight from thetires.

Buying New TiresGM has developed and matchedspecific tires for the vehicle. Theoriginal equipment tires installedwere designed to meet GeneralMotors Tire Performance CriteriaSpecification (TPC Spec) systemrating. When replacement tires are

needed, GM strongly recommendsbuying tires with the same TPCSpec rating.

GM's exclusive TPC Spec systemconsiders over a dozen criticalspecifications that impact theoverall performance of the vehicle,including brake systemperformance, ride and handling,traction control, and tire pressuremonitoring performance. GM'sTPC Spec number is molded ontothe tire's sidewall near the tiresize. If the tires have an all-seasontread design, the TPC Specnumber will be followed by MS formud and snow. See Tire SidewallLabeling 0 364, for additionalinformation.

GM recommends replacing worntires in complete sets of four.Uniform tread depth on all tireswill help to maintain theperformance of the vehicle.Braking and handling performancemay be adversely affected if all the

tires are not replaced at the sametime. If proper rotation andmaintenance have been done, allfour tires should wear out atabout the same time. See TireRotation 0 376 for information onproper tire rotation. However, if itis necessary to replace only oneaxle set of worn tires, place thenew tires on the rear axle.

Winter tires with the same speedrating as the original equipmenttires may not be available for H, V,W, and ZR speed rated tires. Neverexceed the winter tire's maximumspeed capability when usingwinter tires with a lower speedrating.

Uniform Tire QualityGradingThe following information relatesto the system developed by theUnited States National HighwayTraffic Safety Administration(NHTSA), which grades tires bytreadwear, traction, andtemperature performance. Thisapplies only to vehicles sold in theUnited States. The grades aremolded on the sidewalls of mostpassenger car tires. The UniformTire Quality Grading (UTQG)system does not apply to deeptread, winter tires, compact sparetires, tires with nominal rimdiameters of 10 to 12 inches(25 to 30 cm), or to somelimited-production tires.

While the tires available onGeneral Motors passenger carsand light trucks may vary with

respect to these grades, they mustalso conform to federal safetyrequirements and additionalGeneral Motors Tire PerformanceCriteria (TPC) standards.

Quality grades can be found whereapplicable on the tire sidewallbetween tread shoulder andmaximum section width. Forexample:

Treadwear 200 Traction AATemperature A

All Passenger Car Tires MustConform to Federal SafetyRequirements In Addition ToThese Grades.

Treadwear

The treadwear grade is acomparative rating based on thewear rate of the tire when testedunder controlled conditions on aspecified government test course.For example, a tire graded150 would wear one and one-half(1½) times as well on the

government course as a tiregraded 100. The relativeperformance of tires dependsupon the actual conditions oftheir use, however, and maydepart significantly from the normdue to variations in driving habits,service practices and differencesin road characteristics andclimate.

Traction

The traction grades, from highestto lowest, are AA, A, B, and C.Those grades represent the tire'sability to stop on wet pavement asmeasured under controlledconditions on specifiedgovernment test surfaces ofasphalt and concrete. A tiremarked C may have poor tractionperformance. Warning: Thetraction grade assigned to this tireis based on straight-ahead brakingtraction tests, and does not

include acceleration, cornering,hydroplaning, or peak tractioncharacteristics.

Temperature

The temperature grades are A (thehighest), B, and C, representingthe tire's resistance to thegeneration of heat and its abilityto dissipate heat when testedunder controlled conditions on aspecified indoor laboratory testwheel. Sustained high temperaturecan cause the material of the tireto degenerate and reduce tire life,and excessive temperature canlead to sudden tire failure. Thegrade C corresponds to a level ofperformance which all passengercar tires must meet under theFederal Motor Safety StandardNo. 109. Grades B and A representhigher levels of performance onthe laboratory test wheel than theminimum required by law.Warning: The temperature gradefor this tire is established for a tire

that is properly inflated and notoverloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heatbuildup and possible tire failure.

Wheel Alignment and TireBalanceThe tires and wheels were aligned andbalanced at the factory to provide thelongest tire life and best overallperformance. Adjustments to wheelalignment and tire balancing are notnecessary on a regular basis. Consideran alignment check if there is unusualtire wear or the vehicle is significantlypulling to one side or the other. Someslight pull to the left or right,depending on the crown of the roadand/or other road surface variationssuch as troughs or ruts, is normal.If the vehicle is vibrating when drivingon a smooth road, the tires andwheels may need to be rebalanced.See your dealer for proper diagnosis.

Wheel ReplacementReplace any wheel that is bent,cracked, or badly rusted or corroded.If wheel nuts keep coming loose, thewheel, wheel bolts, and wheel nutsshould be replaced. If the wheel leaksair, replace it. Some aluminum wheelscan be repaired. See your dealer if anyof these conditions exist.

Your dealer will know the kind ofwheel that is needed.

Each new wheel should have the sameload-carrying capacity, diameter,width, offset, and be mounted thesame way as the one it replaces.

If a Tire Goes FlatIt is unusual for a tire to blow outwhile driving, especially if the tires aremaintained properly. See Tires 0 362.If air goes out of a tire, it is muchmore likely to leak out slowly. But ifthere is ever a blowout, here are a fewtips about what to expect and whatto do:

If a front tire fails, the flat tire createsa drag that pulls the vehicle towardthat side. Take your foot off theaccelerator pedal and grip the steeringwheel firmly. Steer to maintain laneposition, and then gently brake to astop, well off the road, if possible.

A rear blowout, particularly on acurve, acts much like a skid and mayrequire the same correction as used ina skid. Stop pressing the acceleratorpedal and steer to straighten thevehicle. It may be very bumpy andnoisy. Gently brake to a stop, well offthe road, if possible.

{ Warning

Driving on a flat tire will causepermanent damage to the tire.Re-inflating a tire after it has beendriven on while severelyunderinflated or flat may cause ablowout and a serious crash. Neverattempt to re-inflate a tire that hasbeen driven on while severelyunderinflated or flat. Have yourdealer or an authorized tire servicecenter repair or replace the flat tireas soon as possible.

Collision Damage RepairIf the vehicle is involved in a collisionand it is damaged, have the damagerepaired by a qualified technicianusing the proper equipment andquality replacement parts. Poorlyperformed collision repairs diminishthe vehicle resale value, and safetyperformance can be compromised insubsequent collisions.

Collision Parts

Genuine GM Collision parts are newparts made with the same materialsand construction methods as the partswith which the vehicle was originallybuilt. Genuine GM Collision parts arethe best choice to ensure that thevehicle's designed appearance,durability, and safety are preserved.The use of Genuine GM parts can helpmaintain the GM New Vehicle LimitedWarranty.

CUSTOMER INFORMATION 441

Recycled original equipment partsmay also be used for repair. Theseparts are typically removed fromvehicles that were total losses in priorcrashes. In most cases, the parts beingrecycled are from undamaged sectionsof the vehicle. A recycled originalequipment GM part may be anacceptable choice to maintain thevehicle's originally designedappearance and safety performance;however, the history of these parts isnot known. Such parts are not coveredby the GM New Vehicle LimitedWarranty, and any related failures arenot covered by that warranty.

Aftermarket collision parts are alsoavailable. These are made bycompanies other than GM and maynot have been tested for the vehicle.As a result, these parts may fit poorly,exhibit premature durability/corrosionproblems, and may not performproperly in subsequent collisions.Aftermarket parts are not covered bythe GM New Vehicle LimitedWarranty, and any vehicle failurerelated to such parts is not covered bythat warranty.

Repair Facility

GM also recommends that you choosea collision repair facility that meetsyour needs before you ever needcollision repairs. Your dealer may havea collision repair center withGM-trained technicians andstate-of-the-art equipment, or be ableto recommend a collision repair centerthat has GM-trained technicians andcomparable equipment.

Insuring the Vehicle

Protect your investment in the GMvehicle with comprehensive andcollision insurance coverage. There aresignificant differences in the quality ofcoverage afforded by variousinsurance policy terms. Manyinsurance policies provide reducedprotection to the GM vehicle bylimiting compensation for damagerepairs by using aftermarket collisionparts. Some insurance companies willnot specify aftermarket collision parts.When purchasing insurance, werecommend that you ensure that thevehicle will be repaired with GMoriginal equipment collision parts.

If such insurance coverage is notavailable from your current insurancecarrier, consider switching to anotherinsurance carrier.

If the vehicle is leased, the leasingcompany may require you to haveinsurance that ensures repairs withGenuine GM Original EquipmentManufacturer (OEM) parts or GenuineManufacturer replacement parts. Readthe lease carefully, as you may becharged at the end of the lease forpoor quality repairs.

If a Crash Occurs

If there has been an injury, callemergency services for help. Do notleave the scene of a crash until allmatters have been taken care of. Movethe vehicle only if its position putsyou in danger, or you are instructed tomove it by a police officer.

Give only the necessary informationto police and other parties involved inthe crash.

Managing the Vehicle DamageRepair Process

In the event that the vehicle requiresdamage repairs, GM recommends thatyou take an active role in its repair.If you have a pre-determined repairfacility of choice, take the vehiclethere, or have it towed there. Specifyto the facility that any requiredreplacement collision parts be originalequipment parts, either new GenuineGM parts or recycled original GMparts. Remember, recycled parts willnot be covered by the GM vehiclewarranty.

Insurance pays the bill for the repair,but you must live with the repair.Depending on your policy limits, yourinsurance company may initially valuethe repair using aftermarket parts.Discuss this with the repairprofessional, and insist on GenuineGM parts. Remember, if the vehicle isleased, you may be obligated to havethe vehicle repaired with Genuine GMparts, even if your insurance coveragedoes not pay the full cost.

If another party's insurance companyis paying for the repairs, you are notobligated to accept a repair valuationbased on that insurance company'scollision policy repair limits, as youhave no contractual limits with thatcompany. In such cases, you can havecontrol of the repair and parts choicesas long as the cost stays withinreasonable limits.

Vehicle Data Recordingand PrivacyThe vehicle has a number ofcomputers that record informationabout the vehicle’s performance andhow it is driven. For example, thevehicle uses computer modules tomonitor and control engine andtransmission performance, to monitorthe conditions for airbag deploymentand deploy them in a crash, and,if equipped, to provide antilockbraking to help the driver control thevehicle. These modules may store datato help the dealer technician servicethe vehicle. Some modules may alsostore data about how the vehicle isoperated, such as rate of fuelconsumption or average speed. Thesemodules may retain personalpreferences, such as radio presets, seatpositions, and temperature settings.

Event Data RecordersThis vehicle is equipped with an eventdata recorder (EDR). The mainpurpose of an EDR is to record, incertain crash or near crash-like

situations, such as an air bagdeployment or hitting a road obstacle,data that will assist in understandinghow a vehicle’s systems performed.The EDR is designed to record datarelated to vehicle dynamics and safetysystems for a short period of time,typically 30 seconds or less. The EDRin this vehicle is designed to recordsuch data as:

. How various systems in yourvehicle were operating;

. Whether or not the driver andpassenger safety belts werebuckled/fastened;

. How far (if at all) the driver wasdepressing the accelerator and/orbrake pedal; and,

. How fast the vehicle was traveling.

These data can help provide a betterunderstanding of the circumstances inwhich crashes and injuries occur.

NoteEDR data are recorded by your vehicleonly if a non-trivial crash situationoccurs; no data are recorded by theEDR under normal driving conditions

and no personal data (e.g., name,gender, age, and crash location) arerecorded. However, other parties, suchas law enforcement, could combinethe EDR data with the type ofpersonally identifying data routinelyacquired during a crash investigation.

To read data recorded by an EDR,special equipment is required, andaccess to the vehicle or the EDR isneeded. In addition to the vehiclemanufacturer, other parties, such aslaw enforcement, that have the specialequipment, can read the informationif they have access to the vehicle orthe EDR.

GM will not access these data or shareit with others except: with the consentof the vehicle owner or, if the vehicleis leased, with the consent of thelessee; in response to an officialrequest by police or similargovernment office; as part of GM'sdefense of litigation through thediscovery process; or, as required bylaw.
