QR codes for the rescue card

The QR code is secured in the fuel filler flapand on the opposite side on the B-pillar. In theevent of an accident, rescue services can usethe QR code to quickly find the appropriaterescue card for your vehicle. The current res-cue card contains the most important infor-mation about your vehicle in a compact form,e.g. the routing of the electric cables.You can find more information at https://portal.aftersales.i.daimler.com.

Data stored in the vehicle

Data recordingThis vehicle is capable of recording diagnosticinformation relating to vehicle operation,mal-functions, and user settings. This may includeinformation about the performance or statusof various systems, including but not limitedto, engine, throttle, steering or brake sys-tems, that is stored and can be read out withsuitable devices, particularly when the vehi-cle is serviced. The data obtained is used toproperly diagnose and service your vehicle orto further optimize and develop vehicle func-tions.

COMAND/mbraceIf the vehicle is equipped with COMAND ormbrace, additional data about the vehicle’soperation, the use of the vehicle in certainsituations, and the location of the vehiclemaybe compiled through COMAND or thembracesystem.For additional information please refer to theCOMAND User Manual and/or the mbraceTerms and Conditions.

Event data recordersThis vehicle is equipped with an event datarecorder (EDR). The main purpose of an EDR

is to record data that will assist in under-standing how a vehicle’s systems performedin certain crash or near crash-like situations,such as during air bag deployment or whenhitting a road obstacle. The EDR is designedto record data related to vehicle dynamicsand safety systems for a short period of time,typically 30 seconds or less.The EDR in this vehicle is designed to recordsuch data as:Rhow various systems in your vehicle areoperatingRwhether or not the driver and passengerseat belts are fastenedRhow far (if at all) the driver is depressing theaccelerator and/or brake pedal andRhow fast the vehicle is travelingThis data can help provide a better under-standing of the circumstances in whichcrashes and injuries occur. NOTE: EDR data isrecorded by your vehicle only if a non-trivialcrash situation occurs; no data is recorded bythe EDR under normal driving conditions andno personal data (e.g., name, gender, age,and crash location) are recorded. However,other parties, such as law enforcement, cancombine the EDR data with the type of per-sonal identification data routinely acquiredduring a crash investigation.To read data recorded by an EDR, specialequipment is required, and access to the vehi-cle or the EDR is needed. In addition to thevehicle manufacturer, other parties that havethe special equipment, such as law enforce-ment, can read the information by accessingthe vehicle or the EDR.EDR data may be used in civil and criminalmatters as a tool in accident reconstruction,accident claims, and vehicle safety. Since theCrash Data Retrieval CDR tool that is used toextract data from the EDR is commerciallyavailable, Mercedes-Benz USA, LLC("MBUSA") expressly disclaims any and all lia-bility arising from the extraction of this infor-mation by unauthorized Mercedes-Benz per-sonnel.

Introduction 27

MBUSA will not share EDR data with otherswithout the consent of the vehicle owners or,if the vehicle is leased, without the consent ofthe lessee. Exceptions to this representationinclude responses to subpoenas by lawenforcement; by federal, state or local gov-ernment; in connection with or arising out oflitigation involving MBUSA or its subsidiariesand affiliates; or, as required by law.Warning: The EDR is a component of theRestraint System Module. Tampering with,altering, modifying or removing the EDR com-ponent may result in a malfunction of theRestraint System Module and other systems.State laws or regulations regarding EDRs thatconflict with federal regulation are pre-emp-ted. This means that in the event of such con-flict, the federal regulation governs. As ofFebruary 2013, 13 states have enacted lawsrelating to EDRs.

Occupant safety

Restraint system: introductionThe restraint system reduces the risk of vehi-cle occupants coming into contact with partsof the vehicle's interior in the event of anaccident. The restraint system can also

reduce the forces to which vehicle occupantsare subjected during an accident.The restraint system comprises:RSeat belt systemRAir bagsRChild restraint systemRChild seat securing systemsThe components of the restraint systemworkin conjunction with each other. They can onlydeploy their protective function if, at all times,all vehicle occupants:Rhave fastened their seat belts correctly(Y page 45)Rhave adjusted their seat and head restraintproperly (Y page 103).

As the driver, you also have to make sure thatthe steering wheel is adjusted correctly.Observe the information relating to the cor-rect driver's seat position (Y page 102).You also have tomake sure that an air bag caninflate properly if deployed (Y page 48).An air bag supplements a correctly worn seatbelt. As an additional safety device, the airbag increases the level of protection for vehi-cle occupants in the event of an accident. Forexample, if, in the event of an accident, theprotection offered by the seat belt is suffi-cient, the air bags are not deployed. When anaccident occurs, only the air bags thatincrease protection in that particular accidentsituation are deployed. However, seat beltsand air bags generally do not protect againstobjects penetrating the vehicle from the out-side.Information on restraint system operationcan be found under "Deployment of Emer-gency Tensioning Devices and air bags"(Y page 57).For more information about children travelingwith you in the vehicle and on child restraintsystems, see "Children in the vehicle"(Y page 60).

Important safety notes

G WARNINGModifications to the restraint system maycause it to no longer work as intended. Therestraint system may then not perform itsintended protective function andmay fail in anaccident or trigger unexpectedly, for example.This poses an increased risk of injury or evenfatal injury.Never modify parts of the restraint system.Never tamper with the wiring, the electroniccomponents or their software.If it is necessary tomodify an air bag system toaccommodate a person with disabilities, con-tact an authorized Mercedes-Benz Center fordetails. USA only: for further information con-tact our Customer Assistance Center at1-800-FOR-MERCedes (1‑800‑367‑6372).

Restraint system warning lampThe functions of the restraint system arechecked after the ignition is switched on andat regular intervals while the engine is run-ning. Therefore, malfunctions can be detec-ted in good time.The 6 restraint system warning lamp inthe instrument cluster lights upwhen the igni-tion is switched on. It goes out no later than afew seconds after the vehicle is started. Thecomponents of the restraint system are inoperational readiness.A malfunction has occurred if the 6restraint system warning lamp:Rdoes not light up after the ignition isswitched onRdoes not go out after a few seconds withthe engine runningRlights up again while the engine is running

G WARNINGIf restraint system is malfunctioning, restraintsystem components may be triggered unin-tentionally or might not be triggered at all inthe event of an accident with a high rate of

vehicle deceleration. This can affect the Emer-gency Tensioning Device or air bag, for exam-ple. This poses an increased risk of injury oreven fatal injury.Have the restraint system checked andrepaired in a qualified specialist workshop assoon as possible.

PASSENGER AIR BAG indicator lamp

PASSENGER AIR BAG OFF indicator lamp:and PASSENGER AIR BAG ON indicatorlamp; are part of the Occupant Classifica-tion System (OCS).The indicator lamps display the status of thefront-passenger front air bag.RPASSENGER AIR BAG OFF: lights up: thefront-passenger front air bag is deactiva-ted. It will then not be deployed in the eventof an accident.RPASSENGER AIR BAG ON; lights up: thefront-passenger front air bag is enabled. If,in the event of an accident, all deploymentcriteria are met, the front-passenger frontair bag is deployed.

Depending on the person in the front-passenger seat, the front-passenger front airbag must either be deactivated or enabled;see the following points. You must make sureof this both before and during a journey.RChildren in a child restraint system:whether the front-passenger front air bag isenabled or deactivated depends on theinstalled child restraint system, and the age

and size of the child. Therefore, be sure toobserve the notes on the "Occupant Clas-sification System (OCS)" (Y page 51) andon "Children in the vehicle" (Y page 60).There youwill also find instructions on rear-ward and forward-facing child restraint sys-tems on the front-passenger seat.RAll other persons: depending on the clas-sification of the person in the front-passenger seat, the front-passenger frontair bag is enabled or deactivated(Y page 51). Be sure to observe the noteson "Seat belts“ (Y page 44) and "Air bags"(Y page 48). There you can also find infor-mation on the correct seat position.

Seat belts

IntroductionSeat belts are the most effective means ofrestricting the movement of vehicle occu-pants in the event of an accident or the vehi-cle rolling over. This reduces the risk of vehi-cle occupants coming into contact with partsof the vehicle interior or being ejected fromthe vehicle. Furthermore, the seat belt helpsto keep the vehicle occupant in the best posi-tion in relation to the air bag.The seat belt system comprises:RSeat beltsREmergency Tensioning Devices and seatbelt force limiters

If the seat belt is pulled by the seat beltextender quickly or with a jerky movement,the belt retractor locks. The belt strap cannotbe extracted any further.The Emergency Tensioning Device tightensthe seat belt in an accident, pulling the beltclose against the body. However it does notpull the vehicle occupant back in the directionof the backrest.The Emergency Tensioning Device does notcorrect an incorrect seat position or the rout-ing of an incorrectly fastened seat belt.

When triggered, seat belt force limiters helpto reduce the force exerted by the seat belt onthe vehicle occupant.The seat belt force limiters for the front seatsare synchronized with the front air bags,which absorb part of the deceleration force.This can reduce the force exerted on the vehi-cle occupants during an accident.

! If the front-passenger seat is unoccupied,do not insert the belt tongue into the buckleof the front-passenger seat. This may oth-erwise lead to the triggering of the Emer-gency Tensioning Device in the event of anaccident, which will then need to bereplaced.

Important safety notesThe use of seat belts and child restraint sys-tems is required by law in:Rall 50 statesRthe U.S. territoriesRthe District of ColumbiaRall Canadian provincesEven where this is not required by law, allvehicle occupants should correctly fastentheir seat belts before starting the journey.

G WARNINGIf the seat belt is incorrectly fastened, it can-not protect as intended. Furthermore, anincorrectly fastened seat belt can cause addi-tional injury, for example, in an accident, dur-ing braking or when abruptly changing direc-tion. This poses an increased risk of injury oreven fatal injury.Make sure that all vehicle occupants areseated properly with a correctly fastened seatbelt.

G WARNINGThe seat belt does not offer the intended levelof protection if you have not moved the back-rest to an almost vertical position. When brak-ing or in the event of an accident, you couldslide underneath the seat belt and sustain

44 Occupant safetySafety

abdomen or neck injuries, for example. Thisposes an increased risk of injury or even fatalinjury.Adjust the seat properly before beginningyour journey. Always ensure that the backrestis in an almost vertical position and that theshoulder section of your seat belt is routedacross the center of your shoulder.

G WARNINGPersons under 5 ft (1.50 m) in height cannotfasten the seat belt correctly without an addi-tional suitable restraint system. If the seatbelt is incorrectly fastened, it cannot protectas intended. Furthermore, an incorrectly fas-tened seat belt can cause additional injury, forexample, in an accident, during braking or anabrupt change of direction. This poses anincreased risk of injury or even fatal injury.For this reason, always secure persons under5 ft (1.50 m) in height in suitable restraintsystems.

If a child younger than 12 years and under 5 ft(1.50 m) in height is traveling in the vehicle:Ralways secure the child in a child restraintsystem suitable for this Mercedes-Benzvehicle. The child restraint system must beappropriate to the age, weight and size ofthe childRalways observe the instructions and safetynotes in the "Children in the vehicle" sec-tion of this Operator's Manual(Y page 60) in addition to the childrestraint system manufacturer's installa-tion instructionsRbe sure to observe the instructions andsafety notes on the "Occupant classifica-tion system (OCS)" (Y page 51)

G WARNINGThe seat belts may not perform their intendedprotective function if:Rthey are damaged, modified, extremelydirty, bleach or dyedRthe seat belt buckle is damaged orextremely dirtyRthe Emergency Tensioning Devices, beltanchorages or inertia reels have beenmodi-fied

Seat belts may sustain non-visible damage inan accident, e.g. due to glass splinters. Modi-fied or damaged seat belts may tear or fail,e.g. in an accident. Modified Emergency Ten-sioning Devices could accidentally trigger orfail to deploy when necessary. This poses anincreased risk of injury or even fatal injury.Never modify the seat belts, Emergency Ten-sioning Devices, belt anchorages or inertiareels. Make sure that the seat belts areundamaged, not worn out and clean. Follow-ing an accident, have the seat belts checkedimmediately at a qualified specialist work-shop.

Only use seat belts that have been approvedfor your vehicle by Mercedes-Benz. Any suchmodifications could invalidate the vehicle'sgeneral operating permit.

Proper use of the seat beltsObserve the safety notes on the seat belt(Y page 44).All vehicle occupants must be wearing theseat belt correctly before beginning the jour-ney. Also make sure that all vehicle occu-pants are always wearing the seat belt cor-rectly while the vehicle is in motion.When fastening the seat belt, always makesure that:Rthe seat belt tongue is only inserted to thebelt buckle belonging to that seat.Rthe seat belt is tight across your body.Avoid wearing bulky clothing, e.g. a wintercoat.

Rthe seat belt is not twisted.Only then can the forces which occur bedistributed over the area of the belt.Rthe shoulder section of the belt is alwaysrouted across the center of your shoulder.The shoulder section of the belt must notcome into contact with your neck or berouted under your arm.Rthe lap belt passes tightly and as low downas possible across your lap.The lap belt must always be routed acrossyour hip joints and not across your abdo-men. This applies particularly to pregnantwomen. If necessary, push the lap beltdown to your hip joint and pull it tight usingthe shoulder section of the belt.Rthe seat belt is not routed across sharp,pointed or fragile objects.If you have such items located on or in yourclothing, e.g. pens, keys or eyeglasses,store these in a suitable place.Ronly one person is using a seat belt at atime.Infants and children must never travel sit-ting on the lap of a vehicle occupant. In theevent of an accident, they could be crushedbetween the vehicle occupant and seatbelt.Robjects are never secured with a seat belt ifthe seat belt is also being used by one of thevehicle's occupants.

Seat belts are only intended to secure andrestrain vehicle occupants. Always observethe "Loading guidelines" for securing objects,luggage or loads (Y page 294).

Fastening seat beltsObserve the safety notes on the seat belt(Y page 44) and the notes on correct use ofseat belts (Y page 45).

G WARNINGIf the seat-belt extender is extended duringthe journey, the seat belt is not fitted properlyon the body. The seat belt can then no longer

perform its intended protective function. Thisposes an increased risk of injury or even fatalinjury.Always make sure that the seat-belt extenderis retracted during a journey.

Belt warning for the driver and frontpassengerThe7 seat belt warning lamp in the instru-ment cluster is a reminder that all occupantsmust fasten their seat belts. It may light upcontinuously or flash. In addition, there maybe a warning tone.Regardless of whether the driver's seat belthas already been fastened, the7 seat beltwarning lamp lights up for six seconds eachtime the engine is started. If, aftersix seconds, the driver or front-passengerseat belt has not been fastened and the doorsare closed, the 7 seat belt warning lamplights up. As soon as the driver's and front-passenger seat belts are fastened or a frontdoor is opened again, the 7 seat beltwarning lamp goes out.If the driver's seat belt is not fastened afterthe engine is started, an additional warningtone will sound. This warning tone stops aftersix seconds or when the driver's seat belt isfastened.If the vehicle's speed exceeds 15 mph(25 km/h) once and the driver's and front-passenger seat belts are not fastened, awarning tone sounds. A warning tone alsosounds with increasing intensity for60 seconds or until the driver or frontpassenger have fastened their seat belts.If the driver or front passenger unfasten theirseat belts during the journey, the seat beltwarning is activated again.

Air bags

IntroductionThe installation point of an air bag can be rec-ognized by the AIR BAG symbol.An air bag complements the correctly fas-tened seat belt. It is no substitute for the seatbelt. The air bag provides additional protec-tion in applicable accident situations.Not all air bags are deployed in an accident.The different air bag systems function inde-pendently from one another (Y page 57).However, no system available today can com-pletely eliminate injuries and fatalities.It is also not possible to rule out a risk of injurycaused by an air bag due to the high speed atwhich the air bag must be deployed.

Important safety notes

G WARNINGIf you do not sit in the correct seat position,the air bag cannot protect as intended andcould even cause additional injury whendeployed. This poses an increased risk ofinjury or even fatal injury.To avoid hazardous situations, always makesure that all of the vehicle's occupants:Rhave fastened their seat belts correctly,including pregnant womenRare sitting correctly andmaintain the great-est possible distance to the air bagsRfollow the following instructionsAlways make sure that there are no objectsbetween the air bag and the vehicle's occu-pants.

RAdjust the seats properly before beginningyour journey. Always make sure that theseat is in an almost upright position. Thecenter of the head restraint must supportthe head at about eye level.RMove the driver's and front-passengerseats as far back as possible. The driver'sseat position must allow the vehicle to bedriven safely.

48 Occupant safetySafety

ROnly hold the steering wheel on the out-side. This allows the air bag to be fullydeployed.RAlways lean against the backrest while driv-ing. Do not lean forwards or lean againstthe door or side window. You may other-wise be in the deployment area of the airbags.RAlways keep your feet in the footwell infront of the seat. Do not put your feet on thedashboard, for example. Your feet may oth-erwise be in the deployment area of the airbag.RFor this reason, always secure persons lessthan 5 ft (1.50 m) tall in suitable restraintsystems. Up to this height, the seat beltcannot be worn correctly.

If a child is traveling in your vehicle, alsoobserve the following notes:RAlways secure children under 12 years ofage and less than 5 ft (1.50 m) in height insuitable child restraint systems.RChild restraint systems should be installedon the rear seats.ROnly secure a child in a rearward-facingchild restraint system on the front-passenger seat when the front-passengerfront air bag is deactivated. If thePASSENGER AIR BAGOFF indicator lamp ispermanently lit, the front-passenger frontair bag is deactivated (Y page 43).RAlways observe the instructions and safetynotes on the "Occupant Classification Sys-tem (OCS)" (Y page 51) and on "Childrenin the vehicle" (Y page 60) in addition tothe child restraint system manufacturer'sinstallation instructions.

Objects in the vehicle interior may pre-vent an air bag from functioning correctly.Before starting your journey and to avoid risksresulting from the speed of the air bag as itdeploys, make sure that:Rthere are no people, animals or objectsbetween the vehicle occupants and an airbag.

Do not place any objects on the dashboarde.g. above the front-passenger front airbag.Rthere are no objects between the seat, doorand B-pillar.Rno hard objects, e.g. coat hangers, hang onthe grab handles or coat hooks.Rno accessories, such as cup holders, areattached to the vehicle within the deploy-ment area of an air bag, e.g. to doors, sidewindows, rear side trim or side walls.Rno heavy, sharp-edged or fragile objectsare in the pockets of your clothing. Storesuch objects in a suitable place.

G WARNINGIf you modify the air bag cover or affix objectssuch as stickers to it, the air bag can no longerfunction correctly. There is an increased riskof injury.Never modify an air bag cover or affix objectsto it.

G WARNINGSensors to control the air bags are located inthe doors. Modifications or work not per-formed correctly to the doors or door panel-ing, as well as damaged doors, can lead to thefunction of the sensors being impaired. The airbags might therefore not function properlyany more. Consequently, the air bags cannotprotect vehicle occupants as they aredesigned to do. There is an increased risk ofinjury.Never modify the doors or parts of the doors.Always have work on the doors or door pan-eling carried out at a qualified specialist work-shop.

Knee bags

Driver's knee bag: deploys under the steer-ing column and front-passenger knee bag;under the glove box. The driver's and front-passenger knee bags are triggered togetherwith the front air bags.The driver's and front-passenger knee bagsoffer additional thigh, knee and lower leg pro-tection for the occupants in the front seats.

Side impact air bags

G WARNINGUnsuitable seat covers could restrict or evenprevent the deployment of the air bags inte-grated into the seats. Consequently, the airbags cannot protect vehicle occupants asthey are designed to do. In addition, the func-tion of the Occupant Classification System(OCS) could be restricted. This poses anincreased risk of injury or even fatal injury.You should only use seat covers that havebeen approved for the respective seat byMercedes-Benz.

Front side impact air bags: and rear sideimpact air bags; deploy next to the outerbolster of the seat backrest.When deployed, the side impact air bag offersadditional thorax protection. It also offersadditional pelvis protection for occupants inthe front seats. However, it does not protectthe:RheadRneckRarms

50 Occupant safetySafety

In the event of a side impact, the side impactair bag is deployed on the side on which theimpact occurs.The side impact air bag on the front-passenger side (front) deploys in the follow-ing situations:Rthe OCS system detects that the front-passenger seat is occupied orRthe belt tongue is engaged in the beltbuckle of the front-passenger seat

If the belt tongue is engaged in the beltbuckle, the side impact air bag on the front-passenger side deploys if an appropriate acci-dent situation occurs. In this case, deploy-ment is independent of whether the front-passenger seat is occupied or not.

Window curtain air bags

Window curtain air bags: are integratedinto the side of the roof frame and deployed inthe area from the A-pillar to the C-pillar.When deployed, the window curtain air bagenhances the level of protection for the head.However, it does not protect the chest orarms.In the event of a side impact, the window cur-tain air bag is deployed on the side on whichthe impact occurs.If the system determines that they can offeradditional protection to that provided by theseat belt, a window curtain air bag may bedeployed in other accident situations(Y page 57).

Occupant Classification System(OCS)

IntroductionThe Occupant Classification System (OCS)categorizes the person in the front-passengerseat. Depending on that result, the front-passenger front air bag and front-passengerknee bag are either enabled or deactivated.The system does not deactivate:Rthe side impact air bagRthe window curtain air bagRthe Emergency Tensioning Devices

PrerequisiteTo be classified correctly, the front passengermust sit:Rwith the seat belt fastened correctlyRin an almost upright position with theirback against the seat backrestRwith their feet resting on the floor, if possi-ble

If the front passenger does not observe theseconditions, OCS may produce a false classi-fication, e.g. because the front passenger:Rtransfers their weight by supporting them-selves on a vehicle armrestRsits in such a way that their weight is raisedfrom the seat cushion

If it is absolutely necessary to install a childrestraint system on the front-passenger seat,be sure to observe the correct positioning ofthe child restraint system. Never placeobjects under or behind the child restraintsystem, e.g. cushions. Fully retract the seatcushion length. The entire base of the childrestraint systemmust always rest on the seatcushion of the front-passenger seat. Thebackrest of the forwards-facing child restraintsystemmust, as far as possible, be resting onthe backrest of the front-passenger seat.The child restraint systemmust not touch theroof or be put under strain by the headrestraint.

If the status of the front-passenger front airbag changes while the vehicle is in motion, anair bag displaymessage appears in the instru-ment cluster (Y page 259). When the front-passenger seat is occupied, always pay atten-tion to the PASSENGER AIR BAG ON andPASSENGERAIRBAGOFF indicator lamps. Beaware of the status of the front-passengerfront air bag both before and during the jour-ney.

G WARNINGIf the PASSENGER AIR BAG OFF indicatorlamp is lit, the front-passenger front air bag isdisabled. It will not be deployed in the event ofan accident and cannot perform its intendedprotective function. A person in the front-passenger seat could then, for example, comeinto contact with the vehicle's interior, espe-cially if the person is sitting too close to thedashboard. This poses an increased risk ofinjury or even fatal injury.When the front-passenger seat is occupied,always ensure that:Rthe classification of the person in the front-passenger seat is correct and the front-passenger front air bag is enabled or disa-bled in accordance with the person in thefront-passenger seatRthe front-passenger seat has been movedback as far back as possible.Rthe person is seated correctly.Make sure, both before and during the jour-ney, that the status of the front-passengerfront air bag is correct.

G WARNINGIf you secure a child in a rearward-facing childrestraint system on the front-passenger seatand the PASSENGER AIR BAG ON indicatorlamp is lit up, the front-passenger front air bagmay deploy in an accident. The child could bestruck by the air bag. This poses an increasedrisk of injury or even fatal injury.

Make sure that the front-passenger front airbag has been disabled. The PASSENGER AIRBAG OFF indicator lamp must be lit.

If the PASSENGER AIR BAG OFF indicatorlamp remains off and/or the PASSENGER AIRBAGON indicator lamp lights up, do not installa rearward-facing child restraint system onthe front-passenger seat. You can find moreinformation on OCS under "Problemswith theOccupant Classification System"(Y page 56).

G WARNINGIf you secure a child in a forward-facing childrestraint system on the front-passenger seatand you position the front-passenger seat tooclose to the dashboard, in the event of anaccident, the child could:Rcome into contact with the vehicle's inte-rior if the PASSENGER AIR BAG OFF indi-cator lamp is lit, for exampleRbe struck by the air bag if the PASSENGERAIR BAG ON is lit up

This poses an increased risk of injury or evenfatal injury.Always move the front-passenger seat as farback as possible and fully retract the seatcushion length. Always make sure that theshoulder belt strap is correctly routed fromthe vehicle seat-belt extender to the shoulderbelt guide on the child restraint system. Theshoulder belt strap must be routed forwardsand downwards from the retracted seat-beltextender. If necessary, adjust the front-passenger seat accordingly. Always observethe child restraint system manufacturer'sinstallation instructions.

Deployment of Emergency TensioningDevices and air bags

Important safety notes

G WARNINGThe air bag parts are hot after an air bag hasbeen deployed. There is a risk of injury.Do not touch the air bag parts. Have adeployed air bag replaced at a qualified spe-cialist workshop as soon as possible.

G WARNINGA deployed air bag no longer offers any pro-tection and cannot provide the intended pro-tection in an accident. There is an increasedrisk of injury.Have the vehicle towed to a qualified special-ist workshop in order to have a deployed airbag replaced.

It is important for your safety and that of yourpassenger to have deployed air bags replacedand to have any malfunctioning air bagsrepaired. This will help to make sure the airbags continue to perform their protectivefunction for the vehicle occupants in theevent of a crash.

G WARNINGPyrotechnic Emergency Tensioning Devicesthat have been deployed are no longer opera-tional and are unable to perform their inten-ded protective function. This poses anincreased risk of injury or even fatal injury.Therefore, have pyrotechnic Emergency Ten-sioning Devices which have been triggeredimmediately replaced at a qualified specialistworkshop.

An electric motor is used by PRE-SAFE® totrigger the tightening of the seat belt in haz-ardous situations. This procedure is reversi-ble.If Emergency Tensioning Devices are trig-gered or air bags are deployed, you will hear abang, and a small amount of powder may also

be released. The 6 restraint system warn-ing lamp lights up.Only in rare cases will the bang affect yourhearing. The powder that is released gener-ally does not constitute a health hazard, but itmay cause short-term breathing difficulties inpeople with asthma or other respiratory prob-lems. To avoid this, youmay wish to get out ofthe vehicle or open the windows as soon as itis safe to do so.Air bags and pyrotechnic Emergency Tension-ing Devices (ETDs) contain perchlorate mate-rial, which may require special handling andregard for the environment. National guide-lines must be observed during disposal. InCalifornia, see www.dtsc.ca.gov/HazardousWaste/Perchlorate/index.cfm.

Method of operationDuring the first stage of a collision, therestraint system control unit evaluates impor-tant physical data relating to vehicle deceler-ation or acceleration, such as:RdurationRdirectionRintensityBased on the evaluation of this data, therestraint system control unit triggers theEmergency Tensioning Devices during a fron-tal or rear collision.An Emergency Tensioning Device can only betriggered, if:Rthe ignition is switched onRthe components of the restraint system areoperational; see "Restraint system warninglamp" (Y page 43)Rthe belt tongue is engaged in the buckle onthe respective front-passenger seat

The front-passenger front air bag is activatedor deactivated depending on the person onthe front-passenger seat. The front-passenger front air bag can only deploy in anaccident if the PASSENGER AIR BAG ON indi-cator lamp is lit. Observe the information onthe PASSENGER AIR BAG indicator lamps(Y page 43).Your vehicle has two-stage front air bags.During the first deployment stage, the frontair bag is filled with propellant gas to reducethe risk of injuries. The front air bag is fullydeployed with the maximum amount of pro-pellant gas if a second deployment thresholdis reached within a few milliseconds.The activation threshold of the EmergencyTensioning Devices and the air bag are deter-mined by evaluating the rate of vehicle decel-eration or acceleration which occurs at vari-ous points in the vehicle. This process is pre-emptive in nature. Deployment should takeplace in good time at the start of the collision.The rate of vehicle deceleration or accelera-tion and the direction of the force are essen-tially determined by:Rthe distribution of forces during the colli-sionRthe collision angleRthe deformation characteristics of the vehi-cleRthe characteristics of the object with whichthe vehicle has collided

Factorswhich can only be seen andmeasuredafter a collision has occurred do not play adecisive role in the deployment of an air bag.

Nor do they provide an indication of air bagdeployment.The vehicle can be deformed considerably,without an air bag being deployed. This is thecase if only parts which are relatively easilydeformed are affected and the rate of decel-eration is not high. Conversely, air bags maybe deployed even though the vehicle suffersonly minor deformation. This is the case if, forexample, very rigid vehicle parts such as lon-gitudinal bodymembers are hit, and sufficientdeceleration occurs as a result.If the restraint system control unit detects aside impact or that the vehicle is rolling over,the relevant restraint system components areactivated independently of one anotherdepending on the apparent type of accident.If the systemdetermines a need for additionalprotection for the vehicle occupants, theEmergency Tensioning Devices are triggered.RSide impact air bags on the side of impact,independently of the Emergency Tension-ing Device and the use of the seat belt onthe driver's seat and in the rear compart-ment seatsThe side impact air bag on the front-passenger side (front) deploys in the fol-lowing situations:- the OCS system detects that the front-passenger seat is occupied or

Introduction

In certain hazardous situations, PRE-SAFE®takes pre-emptive measures to protect thevehicle occupants.

Important safety notes

! Make sure that there are no objects in thefootwell under or behind the seats whenmoving the seats back. There is a risk thatthe seats and/or the objects could be dam-aged.

Despite your vehicle being equipped with thePRE-SAFE® system, the possibility of per-sonal injuries occurring as a result of an acci-dent cannot be eliminated. Always adapt yourdriving style to suit the prevailing road andweather conditions and maintain a safe dis-tance from the vehicle in front. Drive care-fully.

Function

PRE-SAFE® intervenes:Rin emergency braking situations, e.g. whenBAS is activatedRin critical driving situations, e.g. when phys-ical limits are exceeded and the vehicleundersteers or oversteers severelyRvehicles with the Driving Assistance pack-age: when a driver assistance system inter-venes powerfully or the radar sensor sys-

tem detects an imminent danger of colli-sion in certain situations

PRE-SAFE® takes the following measuresdepending on the hazardous situation detec-ted:Rthe front seat belts are pre-tensioned.Rif the vehicle skids, the side windows areclosed so that only a small gap remains.Rif the vehicle skids, the panorama roof withpower tilt/sliding panel and the side win-dows are closed so that only a small gapremains.Rthe front-passenger seat is adjusted if it isin an unfavorable position.Rvehicles with a multicontour seat: the airpressure in the side bolsters of the seatbackrest is increased.

If the hazardous situation passes withoutresulting in an accident, PRE-SAFE® slackensthe belt pre-tensioning. On vehicles with mul-ticontour seats, the air pressure in the sidebolsters is reduced again. All settings madeby PRE-SAFE® can then be reversed.If the seat belt pre-tensioning is not reduced:X Move the seat backrest or seat backslightly when the vehicle is stationary.The seat belt pre-tensioning is reduced andthe locking mechanism is released.

The driving safety systems described onlywork as effectively as possible when there isadequate contact between the tires and theroad surface. Please pay special attention tothe notes on tires, recommended minimumtire tread depths, etc. (Y page 356).Inwintry driving conditions, always usewintertires (M+S tires) and if necessary, snowchains. Only in this way will the driving safetysystems described in this section work aseffectively as possible.

ABS (Anti-lock Braking System)

General informationABS regulates brake pressure in such a waythat the wheels do not lock when you brake.This allows you to continue steering the vehi-cle when braking.The!ABSwarning lamp in the instrumentcluster lights up when the ignition is switchedon. It goes out when the engine is running.

Important safety notes

i Observe the "Important safety notes" sec-tion (Y page 65).

G WARNINGIf ABS is faulty, the wheels could lock whenbraking. The steerability and braking charac-teristics may be severely impaired. Addition-ally, further driving safety systems are deac-tivated. There is an increased danger of skid-ding and accidents.Drive on carefully. Have ABS checked imme-diately at a qualified specialist workshop.

When ABS is malfunctioning, other systems,including driving safety systems, will alsobecome inoperative. Observe the informationon the ABS warning lamp (Y page 281) anddisplay messages which may be shown in theinstrument cluster (Y page 247).ABS works from a speed of about 5 mph(8 km/h), regardless of road-surface condi-

tions. ABS works on slippery surfaces, evenwhen you only brake gently.

BrakingX If ABS intervenes: continue to depress thebrake pedal vigorously until the braking sit-uation is over.

X To make a full brake application:depress the brake pedal with full force.

If ABS intervenes when braking, you will feel apulsing in the brake pedal.The pulsating brake pedal can be an indica-tion of hazardous road conditions, and func-tions as a reminder to take extra care whiledriving.

BAS (Brake Assist System)

General informationBAS operates in emergency braking situa-tions. If you depress the brake pedal quickly,BAS automatically boosts the braking force,thus shortening the stopping distance.

Important safety notes

i Observe the "Important safety notes" sec-tion (Y page 65).

G WARNINGIf BAS is malfunctioning, the braking distancein an emergency braking situation isincreased. There is a risk of an accident.In an emergency braking situation, depressthe brake pedal with full force. ABS preventsthe wheels from locking.

BrakingX Keep the brake pedal firmly depressed untilthe emergency braking situation is over.ABS prevents the wheels from locking.

The brakes will function as usual once yourelease the brake pedal. BAS is deactivated.

- the camera system no longer recognizesa pedestrian as a person due to specialclothing or other objects

- a pedestrian is concealed by otherobjects

- the typical outline of a person is not dis-tinguishable from the background

Following damage to the front end of the vehi-cle, have the configuration and operation ofthe radar sensors checked at a qualified spe-cialist workshop. This also applies to colli-sions at low speeds where there is no visibledamage to the front of the vehicle.Following damage to the windshield, have theconfiguration and operation of the camerasystemchecked at a qualified specialist work-shop.

FunctionTo avoid a collision, BAS PLUS calculates thebrake force necessary if:Ryou approach an obstacle, andRBAS PLUS has detected a risk of collisionWhen driving at a speed under 20 mph(30 km/h): if you depress the brake pedal,BAS PLUS is activated. The increase in brakepressure will be carried out at the last possi-ble moment.When driving at a speed above 20 mph(30 km/h): if you depress the brake pedalsharply, BAS PLUS automatically raises thebrake pressure to a value adapted to the traf-fic situation.BAS PLUS provides braking assistance in haz-ardous situations with vehicles in front withina speed range between 4 mph (7 km/h) and155 mph (250 km/h).

At speeds of up to approximately 44 mph(70 km/h), BAS PLUS can react to:Rstationary objects in the path of your vehi-cle, e.g. stopped or parked vehiclesRpedestrians in the path of your vehicleRobjects crossing your path and that arerecognized in the detection range of thesensors

i If BAS PLUS demands particularly highbraking force, preventative passenger pro-tection measures (PRE-SAFE®) are activa-ted simultaneously.

X Keep the brake pedal depressed until theemergency braking situation is over.ABS prevents the wheels from locking.

Distance warning function

Important safety notesi Observe the "Important safety notes" sec-tion for driving safety systems (Y page 65).

G WARNINGThe distance warning function does not react:Rto people or animalsRto oncoming vehiclesRto crossing trafficRwhen corneringThus, the distance warning function cannotprovide a warning in all critical situations.There is a risk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake.

G WARNINGThe distance warning function cannot alwaysclearly identify objects and complex trafficsituations.In such cases, the distance warning functionmay:Rgive an unnecessary warningRnot give a warningThere is a risk of an accident.Always pay careful attention to the traffic sit-uation and do not rely solely on the distancewarning function.

FunctionX To activate/deactivate: activate or deac-tivate the distance warning function in theon-board computer (Y page 240).

If the distance warning function is not activa-ted, theæ symbol appears in the assis-tance graphics display.The distancewarning function can help you tominimize the risk of a front-end collision witha vehicle ahead or reduce the effects of sucha collision. If the distance warning functiondetects that there is a risk of a collision, youwill be warned visually and acoustically.Starting at a speed of around 4mph (7 km/h),the distance warning function warns you ifyou rapidly approach a vehicle in front. Anintermittent warning tone will then sound,and the· distance warning lamp will lightup in the instrument cluster.X Brake immediately in order to increase thedistance from the vehicle in front.

orX Take evasive action, provided it is safe to doso.

Due to the nature of the system, particularlycomplicated but non-critical driving condi-tions may also cause the system to display awarning.With the help of the radar sensor system, thedistance warning function can detect obsta-

cles that are in the path of your vehicle for anextended period of time.Up to a speed of around 44 mph (70 km/h),the distance warning function can also reactto stationary obstacles, such as stopped orparked vehicles.If you approach an obstacle and the distancewarning function detects a risk of a collision,the system will initially alert you both visuallyand acoustically.

Autonomous braking functionIf the driver does not react to the distancewarning signal in a critical situation, COLLI-SION PREVENTION ASSIST PLUS can assistwith the autonomous braking function.The autonomous braking function:Rgives the driver more time to react to criti-cal driving situationsRcan help the driver to avoid an accident orRreduces the effects of an accidentThe autonomous braking function is availablein the following speed ranges:Rfrom 5 mph (7 km/h) to approx. 65 mph(105 km/h) for moving objectsRfrom 5 mph (7 km/h) to approx. 31 mph(50 km/h) for stationary objects

If the autonomous braking function requires aparticularly high braking force, preventativepassenger protection measures (PRE-SAFE®)are activated simultaneously.

Adaptive Brake Assist

i Observe the "Important safety notes" sec-tion (Y page 65).

Adaptive Brake Assist provides braking assis-tance in hazardous situations at speedsabove 4 mph (7 km/h). It uses radar sensortechnology to assess the traffic situation.

G WARNINGAdaptive Brake Assist cannot always clearlyidentify objects and complex traffic situa-tions.

In such cases, Adaptive Brake Assist can:Rintervene unnecessarilyRnot interveneThere is a risk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake. Terminate theintervention in a non-critical driving situation.

G WARNINGAdaptive Brake Assist does not react:Rto people or animalsRto oncoming vehiclesRto crossing trafficRwhen corneringAs a result, the Adaptive Brake Assist may notintervene in all critical conditions. There is arisk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake.

Due to the nature of the system, particularlycomplicated but non-critical driving condi-tions may also cause Brake Assist to inter-vene.If adaptive Brake Assist is not available due toa malfunction in the radar sensor system, thebrake system remains available with fullbrake boosting effect and BAS.With the help of adaptive Brake Assist, thedistance warning signal can detect obstaclesthat are in the path of your vehicle for anextended period of time.If adaptive Brake Assist detects a risk of col-lision with the vehicle in front, it calculatesthe braking force necessary to avoid a colli-sion. If you apply the brakes forcefully, adap-tive Brake Assist will automatically increasethe braking force to a level suitable for thetraffic conditions.X Keep the brake pedal depressed until theemergency braking situation is over.ABS prevents the wheels from locking.

Adaptive Brake Assist is then deactivated.If adaptive Brake Assist demands particularlyhigh braking force, preventative passengerprotection measures (PRE-SAFE®) are activa-ted simultaneously.Up to a speed of approximately 155 mph(250 km/h), adaptive Brake Assist is capableof reacting to moving objects that havealready been detected as such at least onceover the period of observation.Up to a speed of approximately 44 mph(70 km/h), adaptive Brake Assist reacts tostationary obstacles.

ESP® (Electronic Stability Program)

General notes

i Observe the "Important safety notes" sec-tion (Y page 65).

ESP® monitors driving stability and traction,i.e. power transmission between the tires andthe road surface.If ESP® detects that the vehicle is deviatingfrom the direction desired by the driver, oneor more wheels are braked to stabilize thevehicle. The engine output is also modified tokeep the vehicle on the desired course withinphysical limits. ESP® assists the driver whenpulling away on wet or slippery roads. ESP®can also stabilize the vehicle during braking.

ETS/4ETS (Electronic Traction System)

i Observe the "Important safety notes" sec-tion (Y page 65).

ETS traction control is part of ESP®. On vehi-cles with 4MATIC, 4ETS is part of ESP®.Traction control brakes the drive wheels indi-vidually if they spin. This enables you to pull

away and accelerate on slippery surfaces, forexample if the road surface is slippery on oneside. In addition, more drive torque is trans-ferred to the wheel or wheels with traction.Traction control remains active, even if youdeactivate ESP®.

Important safety notes

G WARNINGIf ESP® is malfunctioning, ESP® is unable tostabilize the vehicle. Additionally, further driv-ing safety systems are deactivated. Thisincreases the risk of skidding and an accident.Drive on carefully. Have ESP® checked at aqualified specialist workshop.

Vehicles without 4MATIC: observe the noteson ESP® (Y page 350) when towing the vehi-cle with a raised rear axle.ESP® is only deactivated if the å warninglamp is lit continuously.If the ÷ warning lamp lights up continu-ously, ESP® is not available due to a malfunc-tion.Observe the information on warning lamps(Y page 283) and display messages whichmay be shown in the instrument cluster(Y page 247).Only use wheels with the recommended tiresizes. Only then will ESP® function properly.

X To activate: (Y page 72).The å ESP® OFF warning lamp in theinstrument cluster goes out.

Characteristics when ESP® is deactivatedIf ESP® is deactivated and one ormorewheelsstart to spin, the ÷ ESP® warning lamp inthe instrument cluster flashes. In such situa-tions, ESP® will not stabilize the vehicle.If you deactivate ESP®:RESP® no longer improves driving stability.Rengine torque is no longer limited and thedrive wheels are able to spin.The spinning of the wheels results in a cut-ting action for better traction on loose sur-faces.Rtraction control is still activated.RESP® still provides support when youbrake.

Crosswind Assist (vehicles withoutMAGIC BODY CONTROL)

General informationVehicles with MAGIC BODY CONTROL: infor-mation on stabilizing the vehicle in the eventof crosswind (Y page 189).Strong crosswinds can cause your vehicle todeviate from a straight course. The crosswinddriving assistance function integrated intoESP® significantly reduces these effects.

72 Driving safety systemsSafety

ESP® intervenes automatically according tothe direction and intensity of the crosswindsaffecting your vehicle.ESP intervenes with stabilizing braking toassist you in keeping the vehicle in the lane.Crosswind Assist is active at vehicle speedsabove 50 mph (80 km/h) when drivingstraight ahead or cornering gently.

Important safety notesCrosswind Assist does not work if ESP® isdeactivated or disabled because of a mal-function.

EBD (electronic brake force distribu-tion)

General informationEBD monitors and controls the brake pres-sure on the rear wheels to improve drivingstability while braking.

Important safety notes

PRE-SAFE® Brake

General information

i Pay attention to the important safetynotes in the "Driving safety systems" sec-tion (Y page 65).

PRE‑SAFE® Brake is only available for vehi-cles with the Driving Assistance package.For PRE-SAFE® Brake to assist you when driv-ing, the radar sensor system and the camerasystem must be switched on and be opera-tional.With the help of the radar sensor system andthe camera system, PRE-SAFE® Brake candetect obstacles that are in front of your vehi-cle for an extended period of time.In addition, pedestrians in the path of yourvehicle can be detected.PRE-SAFE® Brake detects pedestrians usingtypical characteristics such as the body con-tours and posture of a person standingupright.Observe the restrictions described in the"Important safety notes" sec-tion“ (Y page 73).PRE-SAFE® Brake can help you to minimizethe risk of a collision with a vehicle ahead or apedestrian, and reduce the effects of such acollision. If PRE-SAFE® Brake has detected arisk of collision, you will be warned visuallyand acoustically as well as by automatic brak-ing.

Important safety notes

G WARNINGPRE-SAFE® Brake will initially brake your vehi-cle by a partial application of the brakes if adanger of collision is detected. There may bea collision unless you brake yourself. Evenafter subsequent full application of the brakes

a collision cannot always be avoided, partic-ularly when approaching at too high a speed.There is a risk of an accident.Always apply the brakes yourself and try totake evasive action, provided it is safe to doso.

G WARNINGPRE-SAFE® Brake cannot always clearly iden-tify objects and complex traffic conditions.In these cases, PRE-SAFE® Brake may:Rgive an unnecessary warning and thenbrake the vehicleRnot give a warning or interveneThere is a risk of an accident.Always pay particular attention to the trafficsituation and be ready to brake, especially ifPRE-SAFE® Brake warns you. Terminate theintervention in a non-critical driving situation.

In order to maintain the appropriate distanceto the vehicle in front and thus prevent a col-lision, you must apply the brakes yourself.PRE-SAFE® Brake can also brake the vehicleautomatically under the following conditions:Rthe driver and front-passenger have theirseat belts fastenedandRthe vehicle speed is between approx-imately 4 mph (7 km/h) and 124 mph(200 km/h)

At a speed of up to approximately 44 mph(70 km/h), PRE-SAFE®Brake can also detect:Rstationary objects in the path of your vehi-cle, e.g. stopped or parked vehiclesRpedestrians in the path of your vehicle

G WARNINGPRE-SAFE® Brake does not react:Rto small people, e.g. childrenRto animalsRto oncoming vehicles

Rto crossing trafficRwhen corneringAs a result, PRE-SAFE® Brake may neithergive warnings nor intervene in all critical sit-uations. There is a risk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake.

In the event of snowfall or heavy rain, the rec-ognition can be impaired.Recognition by the radar sensor system isalso impaired in the event of:Rthere is dirt on the sensors or anything elsecovering the sensorsRthere is interference by other radar sourcesRthere are strong radar reflections, forexample in parking garagesRa narrow vehicle traveling in front, e.g. amotorbikeRa vehicle traveling in front on a different linerelative to the center of your vehicle

Recognition by the camera system is alsoimpaired in the event of:Rdirt on the camera or if the camera is cov-eredRthere is glare on the camera system, e.g.from the sun being low in the skyRdarknessRif:

- pedestrians move quickly, e.g. into thepath of the vehicle

- the camera system no longer recognizesa pedestrian as a person due to specialclothing or other objects

- a pedestrian is concealed by otherobjects

- the typical outline of a person is not dis-tinguishable from the background

Following damage to the front end of the vehi-cle, have the configuration and operation ofthe radar sensors checked at a qualified spe-cialist workshop. This also applies to colli-sions at low speeds where there is no visibledamage to the front of the vehicle.

74 Driving safety systemsSafety

Following damage to the windshield, have theconfiguration and operation of the camerasystemchecked at a qualified specialist work-shop.

FunctionX To activate/deactivate: activate or deac-tivate PRE-SAFE® Brake in the on-boardcomputer (Y page 241).If the PRE-SAFE®Brake is not activated, theæ symbol appears in the multifunctiondisplay.

Exterior lighting

General notesFor reasons of safety, Mercedes-Benz recom-mends that you drive with the lights switchedon even during the daytime. In some coun-tries, operation of the headlamps varies dueto legal requirements and self-imposed obli-gations.

Driving abroad

Symmetrical low-beam headlampsSwitch the headlamps to symmetrical lowbeam in countries in which traffic drives onthe opposite side of the road from the countrywhere the vehicle is registered. This preventsglare to oncoming traffic. When using sym-metrical lights, the edge of the road is not litas widely and as far ahead as normal.Have the headlamps converted at a qualifiedspecialist workshop as close to the border aspossible before driving in these countries.

Asymmetrical low beamHave the headlamps converted back to asym-metrical low-beam headlamps at a qualifiedspecialist workshop as soon as possible aftercrossing the border again.

Adaptive Highbeam Assist Plus

General notes

With Adaptive Highbeam Assist Plus, you canautomatically switch between low-beam, par-tial high-beam and high-beam headlamps.Partial high-beam is a form of illuminationwhereby the high-beam is directed past otherroad users. Other road users are kept out ofthe high-beam. This prevents glare. Whenthere is a vehicle in front, for example, thehigh-beam headlamps illuminate the areas toits right and left, and the vehicle in front isilluminated by the low-beam headlamps.The system automatically adapts the low-beam headlamp range depending on the dis-tance to the other vehicle. Once the systemno longer detects any other vehicles, it reac-tivates the high-beam headlamps.If the high-beam or partial high-beam arecausing too much reflection from trafficsigns, the lights are automatically dimmedand glare for the driver caused by the reflec-tions is thus avoided.The system's optical sensor is located behindthe windshield near the overhead controlpanel.

Important safety notes

G WARNINGAdaptive Highbeam Assist Plus does not rec-ognize road users:Rwho have no lights, e.g. pedestriansRwho have poor lighting, e.g. cyclistsRwhose lighting is blocked, e.g. by a barrierIn very rare cases, Adaptive Highbeam AssistPlus may not recognize road users who dohave lights, or may recognize them too late. Inthis or similar situations, the automatic high-beam headlamps will not be deactivated orwill be activated regardless. There is a risk ofan accident.Always carefully observe the traffic conditionsand switch off the high-beam headlamps ingood time.

Adaptive Highbeam Assist Plus cannot takeinto account road, weather or traffic condi-tions. Adaptive Highbeam Assist Plus is onlyan aid. You are responsible for adjusting thevehicle's lighting to the prevailing light, visi-bility and traffic conditions.In particular, the detection of obstacles canbe restricted if there is:Rpoor visibility, e.g. due to fog, heavy rain orsnowRdirt on the sensors or the sensors areobscured

You must therefore make sure thatthese function correctly at all times. Have theheadlamp setting checked regularly.

Windshield wipers

Switching the windshield wiperson/off! Do not operate the windshield wiperswhen the windshield is dry, as this coulddamage the wiper blades. Moreover, dustthat has collected on the windshield canscratch the glass if wiping takes placewhenthe windshield is dry.If it is necessary to switch on thewindshieldwipers in dry weather conditions, alwaysuse washer fluid when operating the wind-shield wipers.

! If the windshield wipers leave smears onthe windshield after the vehicle has beenwashed in an automatic car wash, wax orother residues may be the reason for this.Clean the windshield using washer fluid

126 Windshield wipersLightsandwindshieldwipers

after washing the vehicle in an automaticcar wash.

! Vehicles with a rain sensor: if the wind-shield becomes dirty in dry weather condi-tions, the windshield wipers may be activa-ted inadvertently. This could then damagethe windshield wiper blades or scratch thewindshield.For this reason, you should always switchoff the windshield wipers in dry weather.

i This Operator's Manual describes allmodels and all standard and optional equip-ment of your vehicle available at the time ofpublication of the Operator's Manual.Country-specific differences are possible.Please note that your vehicle may not beequipped with all features described. Thisalso applies to safety-related systems andfunctions.

Overview of climate control systems

General notesObserve the settings recommended on thefollowing pages. The windows could other-wise fog up.To prevent the windows from fogging up:Rswitch off climate control only brieflyRswitch on air-recirculation mode onlybrieflyRswitch on the cooling with air dehumidifi-cation functionRswitch on the defrost windshield functionbriefly, if required

Climate control regulates the temperatureand air humidity in the vehicle interior. The airfilter cleans the air, thus improving the inte-rior climate.The "Cooling with air dehumidification" func-tion is only available when the engine is run-ning. Optimum climate control is only ach-ieved with the side windows and roof closed.The residual heat function can only be acti-vated or deactivated with the ignitionswitched off (Y page 139).

i Ventilate the vehicle for a brief periodduring warm weather, e.g. using the con-venience opening feature (Y page 95). Thiswill speed up the cooling process and the

desired interior temperature will bereached more quickly.

i The integrated filter filters out most par-ticles of dust and soot and completely fil-ters out pollen. It also reduces gaseous pol-lutants and odors. A clogged filter reducesthe amount of air supplied to the vehicleinterior. For this reason, you should alwaysobserve the interval for replacing the filter,which is specified in the MaintenanceBooklet. As it depends on environmentalconditions, e.g. heavy air pollution, theinterval may be shorter than stated in theMaintenance Booklet.

i It is possible that the blower may be acti-vated automatically 60 minutes after theSmartKey has been removed depending onvarious factors, e.g. the outside tempera-ture. The vehicle is then ventilated for30 minutes to dry the climate control sys-tem.

Notes on breaking-in a new vehicle

Important safety notesThe sensor system of some driving and driv-ing safety systems adjusts automaticallywhile a certain distance is being driven afterthe vehicle has been delivered or afterrepairs. Full system effectiveness is notreached until the end of this teach-in proce-dure.New and replaced brake pads and discs onlyreach their optimum braking effect after sev-eral hundred kilometers of driving. Compen-sate for this by applying greater force to thebrake pedal.

The first 1000 miles (1500 km)The more you look after the engine when it isnew, the more satisfied you will be with itsperformance in the future.RYou should therefore drive at varying vehi-cle and engine speeds for the first1000 miles (1500 km).RAvoid heavy loads, e.g. driving at full throt-tle, during this period.RWhen shifting gears manually, upshift ingood time, before the tachometer needlereachesÔ of the way to the red area of thetachometer.

RDo not manually shift to a lower gear tobrake the vehicle.RTry to avoid depressing the acceleratorpedal beyond the point of resistance (kick-down).RAll vehicles (except AMG vehicles): ide-ally, for the first 1,000 miles (1,500 km),drive in program E.

Additional breaking-in notes for AMG vehi-cles:RDo not drive faster than 85 mph(140 km/h) for the first 1,000 miles(1,500 km).ROnly allow the engine to reach a maximumengine speed of 4,500 rpm briefly.RChange gear in good time.RIdeally, for the first 1,000miles (1,500 km),drive in program C.

After 1000miles (1500 km), you can increasethe engine speed gradually and acceleratethe vehicle to full speed.You should also observe these notes onbreaking in if the engine or parts of the drivetrain on your vehicle have been replaced.Always observe the respective speed limits.

G WARNINGIf you switch off the ignition while driving,safety-relevant functions are only availablewith limitations, or not at all. This could affect,for example, the power steering and the brakeboosting effect. You will require considerablymore effort to steer and brake. There is a riskof an accident.Do not switch off the ignition while driving.

G WARNINGIf the parking brake has not been fullyreleased when driving, the parking brake can:Roverheat and cause a fireRlose its hold function.There is a risk of fire and an accident. Releasethe parking brake fully before driving off.

! Do not warm up the engine with the vehi-cle stationary. Drive off immediately. Avoidhigh engine speeds and driving at full throt-tle until the engine has reached its operat-ing temperature.Only shift the automatic transmission tothe desired drive position when the vehicleis stationary.Where possible, avoid spinning the drivewheels when pulling away on slipperyroads. You could otherwise damage thedrive train.

! AMG vehicles: at low engine oil temper-atures below 68 ‡ (+20 †), the maximumengine speed is restricted in order to pro-tect the engine. To protect the engine and

maintain smooth engine operation, avoiddriving at full throttle when the engine iscold.

Important safety notes

G WARNINGIf you switch off the ignition while driving,safety-relevant functions are only availablewith limitations, or not at all. This could affect,for example, the power steering and the brakeboosting effect. You will require considerablymore effort to steer and brake. There is a riskof an accident.Do not switch off the ignition while driving.

G WARNINGIf you operate mobile communication equip-ment while driving, you will be distracted fromtraffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.Only operate this equipment when the vehicleis stationary.

Observe the legal requirements for the coun-try in which you are driving. Some jurisdic-tions prohibit the driver from using a mobilephone while driving a vehicle.If you make a call while driving, always usehands-freemode. Only operate the telephonewhen the traffic situation permits. If you areunsure, pull over to a safe location and stopbefore operating the telephone.Bear in mind that at a speed of only 30 mph(approximately 50 km/h), the vehicle coversa distance of 44 ft (approximately 14 m) persecond.

Drive sensibly – save fuelObserve the following tips to save fuel:X The tires should always be inflated to therecommended tire pressure.

X Remove unnecessary loads.X Remove roof racks when they are not nee-ded.

X Warm up the engine at low engine speeds.

X Avoid frequent acceleration or braking.X Have all maintenance work carried out asindicated by the service intervals in theMaintenance Booklet or by the serviceinterval display.

Fuel consumption also increases when driv-ing in cold weather, in stop-start traffic and inhilly terrain.

Drinking and driving

G WARNINGDrinking and driving and/or taking drugs anddriving are very dangerous combinations.Even a small amount of alcohol or drugs canaffect your reflexes, perceptions and judg-ment.The possibility of a serious or even fatal acci-dent is greatly increased when you drink ortake drugs and drive.Do not drink or take drugs and drive or allowanyone to drive who has been drinking or tak-ing drugs.

Emission control

G WARNINGCombustion engines emit poisonous exhaustgases such as carbon monoxide. Inhalingthese exhaust gases leads to poisoning. Thereis a risk of fatal injury. Therefore never leavethe engine running in enclosed spaces with-out sufficient ventilation.

Certain engine systems are designed to keepthe level of poisonous components in exhaustfumes within legal limits.These systems only work at peak efficiency ifthey are serviced exactly in accordance withthe manufacturer's specifications. For thisreason, all work on the enginemust be carriedout by qualified and authorized Mercedes-Benz technicians.The engine settings must not be changedunder any circumstances. Furthermore, allspecific service work must be carried out at

170 Driving tipsDrivingandparking

regular intervals and in accordance with theMercedes-Benz service requirements. Detailscan be found in the Maintenance Booklet.

ECO display

The ECO display provides feedback on howeconomical your driving characteristics are.The ECO display assists you in achieving themost economical driving style for the selec-ted settings and prevailing conditions. Yourdriving style can significantly influence thevehicle's consumption.The ECO display consists of three bars:RAccelerationAccelerationRConstantConstantRCoastingCoastingThe percent value is the average value of thethree bars. The three bars and themean valuebegin at the value of 50%. A higher percent-age indicates a more economical drivingstyle.The ECO display does not indicate the actualfuel consumption. A fixed percentage countin the ECO display does not indicate a fixedconsumption.Apart from driving style, consumption isdependent on many factors such as, e.g.:RloadRtire pressureRcold startRchoice of routeRelectrical consumers switched on

These factors are not included in the ECO dis-play.The evaluation of your driving style is carriedout using the following three categories:RAccelerationAcceleration (evaluation of all accelera-tion processes):- The bar fills up: moderate acceleration,especially at higher speeds

- The bar empties: sporty accelerationRConstantConstant (assessment of driving behaviorat all times):- The bar fills up: constant speed andavoidance of unnecessary accelerationand deceleration

- The bar empties: fluctuations in speedRCoastingCoasting (assessment of all decelerationprocesses):- The bar fills up: anticipatory driving,keeping your distance and early releaseof the accelerator. The vehicle can coastwithout use of the brakes.

- The bar empties: frequent brakingAn economical driving style specially requiresdriving at moderate engine speeds.To achieve a higher value in the categoriesAccelerationAcceleration and ConstantConstant:Robserve the gearshift recommendations.Rdrive in drive program E.On long journeys at a constant speed, e.g. onthe highway, only the bar for ConstantConstant willchange.The ECO display summarizes the driving char-acteristics from the start of the journey to itscompletion. For this reason, the bars changedynamically at the beginning of the journey.On longer journeys, there are fewer changes.For more dynamic changes, carry out a man-ual reset.For further information on the ECO display,see (Y page 232).

Braking

Important safety notes

G WARNINGIf you shift down on a slippery road surface inan attempt to increase the engine's brakingeffect, the drive wheels could lose their grip.There is an increased danger of skidding andaccidents.Do not shift down for additional engine brak-ing on a slippery road surface.

Downhill gradients

! On long and steep gradients, you mustreduce the load on the brakes by shiftingearly to a lower gear. This allows you to takeadvantage of the engine braking effect andhelps avoid overheating and excessivewear of the brakes.When you take advantage of the enginebraking effect, a drive wheel may not turnfor some time, e.g. on a slippery road sur-face. This could cause damage to the drivetrain. This type of damage is not covered bythe Mercedes-Benz warranty.

Heavy and light loads

G WARNINGIf you rest your foot on the brake pedal whiledriving, the braking system can overheat. Thisincreases the stopping distance and can evencause the braking system to fail. There is arisk of an accident.Never use the brake pedal as a footrest. Neverdepress the brake pedal and the acceleratorpedal at the same time.

! Depressing the brake pedal constantlyresults in excessive and premature wear tothe brake pads.

If the brakes have been subjected to a heavyload, do not stop the vehicle immediately.Drive on for a short while. This allows the air-flow to cool the brakes more quickly.

Wet roadsIf you have driven for a long time in heavy rainwithout braking, theremay be a delayed reac-tion from the brakeswhen braking for the firsttime. Thismay also occur after the vehicle hasbeen washed or driven through deep water.You have to depress the brake pedal morefirmly. Maintain a greater distance from thevehicle in front.After driving on a wet road or having the vehi-cle washed, brake firmly while paying atten-tion to the traffic conditions. Thiswill warmupthe brake discs, thereby drying them morequickly and protecting them against corro-sion.

Limited braking performance on salt-treated roadsIf you drive on salted roads, a layer of saltresidue may form on the brake discs andbrake pads. This can result in a significantlylonger braking distance.RIn order to prevent any salt build-up, applythe brakes occasionally while paying atten-tion to the traffic conditions.RCarefully depress the brake pedal and thebeginning and end of a journey.RMaintain a greater distance to the vehicleahead.

Servicing the brakes

! If the red brake warning lamp lights up inthe instrument cluster and you hear awarn-ing tone while the engine is running, thebrake fluid level may be too low. Observeadditional warning messages in the multi-function display.The brake fluid level may be too low due tobrake pad wear or leaking brake lines.Have the brake system checked immedi-ately. This work should be carried out at aqualified specialist workshop.

! Vehicles with 4MATIC: function or per-formance tests may only be carried out on

172 Driving tipsDrivingandparking

a 2-axle dynamometer. If you wish to oper-ate the vehicle on such a dynamometer,please consult an authorized Mercedes-Benz Center in advance. You could other-wise damage the drive train or the brakesystem.

! Vehicleswith 4MATIC: the ESP® systemoperates automatically. The engine and theignitionmust therefore be switched off (theSmartKey must be in position 0 or 1 in theignition lock or the Start/Stop button mustbe in position 0 or 1) if the electric parkingbrake is tested on a brake dynamometer.Braking triggered automatically by ESP®may cause severe damage to the brakesystem.

! Vehicles without 4MATIC: the ESP®system operates automatically. The engineand the ignitionmust therefore be switchedoff (the SmartKeymust be in position0 or1in the ignition lock or the Start/Stop buttonmust be in position 0 or 1) if:Rthe electric parking brake is tested usinga brake dynamometer.Rthe vehicle is towed with one axle raised.Braking triggered automatically by ESP®may cause severe damage to the brakesystem.

All checks and maintenance work on thebrake system must be carried out at a quali-fied specialist workshop. Consult a qualifiedspecialist workshop to arrange this.Have brake pads installed and brake fluidreplaced at a qualified specialist workshop.If the brake system has only been subject tomoderate loads, you should test the function-ality of your brakes at regular intervals.Information on BAS (Brake Assist) (Y page 66)and BAS PLUS (Brake Assist PLUS)(Y page 67).

For safety reasons, Mercedes-Benz recom-mends only installing the following brakedisks and brake pads/linings:Rbrake disks that have been approved byMercedes-BenzRbrake pads/linings that have beenapproved by Mercedes-Benz or that are ofan equivalent standard of quality

Other brake disks or brake pads/linings cancompromise the safety of your vehicle.Always replace all brake disks and brakepads/linings on an axle at the same time.Always install new brake pads/linings whenreplacing brake disks.The vehicle is equipped with lightweightbrake disks to which the wheel assembly withrim and threaded connection is matched.The use of brake disks other than thoseapproved by Mercedes-Benz can change thetrackwidth and is subject to approval, if appli-cable.Shock-type loads when handling the brakedisks, such as when changing wheels, canlead to a reduction in comfort when drivingwith lightweight brake disks. Avoid shock-type loads on the lightweight brake disks,particularly on the brake plate.Mercedes-Benz recommends that you onlyuse brake fluid that has been speciallyapproved for your vehicle by Mercedes-Benz,or which corresponds to an equivalent qualitystandard. Brake fluid which has not beenapproved for Mercedes-Benz vehicles orwhich is not of an equivalent quality couldaffect your vehicle's operating safety.

The AMG brake systems are designed forheavy loads. This may lead to noise whenbraking. This will depend on:RspeedRbraking forceRenvironmental conditions, such as temper-ature and humidity

The wear of individual components of thebrake system, such as the brake pads/liningsor brake discs, depends on the individual driv-ing style and operating conditions.For this reason, it is impossible to state amileage that will be valid under all circum-stances. An aggressive driving style will leadto high wear. You can obtain further informa-tion about this from your authorizedMercedes-Benz Center.New and replaced brake pads and discs onlyreach their optimum braking effect after sev-eral hundred kilometers of driving. Compen-sate for this by applying greater force to thebrake pedal. Keep this in mind, and adaptyour driving and braking accordingly duringthis break-in period.Excessive heavy braking results in corre-spondingly high brake wear. Observe thebrake wear warning lamp in the instrumentcluster and note any brake status messagesin the multifunction display. Especially forhigh performance driving, it is important tomaintain and have the brake system checkedregularly.

Driving on wet roads

HydroplaningIf water has accumulated to a certain depthon the road surface, there is a danger ofhydroplaning occurring, even if:Ryou drive at low speeds.Rthe tires have adequate tread depth.

For this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:Rlower your speed.Ravoid ruts.Ravoid sudden steering movements.Rbrake carefully.

Driving on flooded roads

! Do not drive through flooded areas.Check the depth of anywater before drivingthrough it. Drive slowly through standingwater. Otherwise, water may enter thevehicle interior or the engine compartment.This can damage the electronic compo-nents in the engine or the automatic trans-mission. Water can also be drawn in by theengine's air suction nozzles and this cancause engine damage.

Winter driving

G WARNINGIf you shift down on a slippery road surface inan attempt to increase the engine's brakingeffect, the drive wheels could lose their grip.There is an increased danger of skidding andaccidents.Do not shift down for additional engine brak-ing on a slippery road surface.

G DANGERIf the exhaust pipe is blocked or adequateventilation is not possible, poisonous gasessuch as carbon monoxide (CO) may enter thevehicle. This is the case, e.g. if the vehiclebecomes trapped in snow. There is a risk offatal injury.If you leave the engine or the auxiliary heatingrunning, make sure the exhaust pipe and areaaround the vehicle are clear of snow. Toensure an adequate supply of fresh air, open awindow on the side of the vehicle that is notfacing into the wind.

174 Driving tipsDrivingandparking

Have your vehicle winterproofed at a qualifiedspecialist workshop at the onset of winter.Drive particularly carefully on slippery roadsurfaces. Avoid sudden acceleration, steeringand brakingmaneuvers. Do not use the cruisecontrol or DISTRONIC PLUS.If the vehicle threatens to skid or cannot bestopped when moving at low speed:X Shift the transmission to position N.The outside temperature indicator is notdesigned to serve as an ice-warning deviceand is therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.Indicated temperatures just above the freez-ing point do not guarantee that the road sur-face is free of ice. The road may still be icy,especially in wooded areas or on bridges.You should pay special attention to road con-ditions when temperatures are around freez-ing point.For more information on driving with snowchains, see (Y page 359).For more information on driving with summertires, see (Y page 358).Observe the notes in the "Winter operation"section (Y page 358).

Cruise control

General notesCruise control maintains a constant roadspeed for you. It brakes automatically in orderto avoid exceeding the set speed. Change intoa lower gear in good time on long and steepdownhill gradients. This is especially impor-tant if the vehicle is laden. By doing so, youwill make use of the braking effect of theengine. This relieves the load on the brakesystem and prevents the brakes from over-heating and wearing too quickly.Use cruise control only if road and traffic con-ditions make it appropriate to maintain asteady speed for a prolonged period. You canstore any road speed above 20 mph(30 km/h).

Important safety notesIf you fail to adapt your driving style, cruisecontrol can neither reduce the risk of an acci-dent nor override the laws of physics. Cruisecontrol cannot take into account the road,traffic and weather conditions. Cruise controlis only an aid. You are responsible for the dis-tance to the vehicle in front, for vehicle speed,for braking in good time and for staying inyour lane.Do not use cruise control:Rin road and traffic conditions which do notallow you to maintain a constant speed e.g.in heavy traffic or on winding roadsRon slippery road surfaces. Braking or accel-erating could cause the drivewheels to losetraction and the vehicle could then skidRwhen there is poor visibility, e.g. due to fog,heavy rain or snow

If there is a change of drivers, advise the newdriver of the speed stored.

Tips for driving with DISTRONIC PLUS

General notesPay particular attention in the following trafficsituations:RCornering, going into and coming out of abendRVehicles traveling on a different lineROther vehicles changing lanesRNarrow vehiclesRObstructions and stationary vehiclesRCrossing vehiclesIn such situations, brake if necessary.DISTRONIC PLUS is then deactivated.

184 Driving systemsDrivingandparking

Cornering, going into and coming out of abend

The ability of DISTRONIC PLUS to detect vehi-cles when cornering is limited. Your vehiclemay brake unexpectedly or late.

Vehicles traveling on a different line

DISTRONIC PLUS may not detect vehiclestraveling on a different line. The distance tothe vehicle in front will be too short.

Other vehicles changing lanes

DISTRONIC PLUS has not detected the vehi-cle cutting in yet. The distance to this vehiclewill be too short.

Narrow vehicles

DISTRONIC PLUS has not yet detected thevehicle in front on the edge of the road,because of its narrow width. The distance tothe vehicle in front will be too short.

Obstructions and stationary vehicles

DISTRONIC PLUS does not brake for obsta-cles or stationary vehicles. If, for example, thedetected vehicle turns a corner and revealsan obstacle or stationary vehicle, DISTRONICPLUS will not brake for these.

Crossing vehicles

DISTRONIC PLUS may mistakenly detectvehicles that are crossing your lane. Activat-ing DISTRONIC PLUS at traffic lights withcrossing traffic, for example, could causeyour vehicle to pull away unintentionally.

DISTRONIC PLUS with Steering Assistand Stop&Go Pilot

General notes

DISTRONIC PLUS with Steering Assist andStop&Go Pilot aids you in keeping the vehiclein the center of the driving lane by means ofmoderate steering interventions at speeds of0 - 125 mph (0 - 200 km/h).It monitors the area in front of your vehicle bymeans of camera system: at the top of thewindshield.At speeds of 0 - 37 mph (0 - 60 km/h),Stop&Go Pilot focuses on the vehicle in front,taking into account lane markings, e.g. whenfollowing vehicles in a traffic jam.At speeds of more than 37 mph (60 km/h)Steering Assist focuses on detected lane

markings (left and right), and only on the vehi-cle in front if lane markings are missing.Steering Assist and Stop&Go Pilot do not pro-vide any support if these conditions do notexist.DISTRONIC PLUS must be active in order forthe function to be available.

Important safety notesIf you fail to adapt your driving style,DISTRONIC PLUS with Steering Assist andStop&Go Pilot can neither reduce the risk ofan accident nor override the laws of physics.It cannot take account of road, weather andtraffic conditions. DISTRONIC PLUS withSteering Assist and Stop&Go Pilot is only anaid. You are responsible for the distance tothe vehicle in front, for vehicle speed, forbraking in good time and for staying in yourlane.DISTRONIC PLUS with Steering Assist andStop&Go Pilot does not detect road and traf-fic conditions. If you are following a vehiclewhich is driving towards the edge of the road,your vehicle could come into contact with thecurb or other road boundaries. Be particularlyaware of other road users, e.g. cyclists, thatare directly next to your vehicle.Obstacles such as building site huts on thelane or projecting out into the lane are notdetected.An inappropriate steering intervention, e.g.after intentionally driving over a lanemarking,can be corrected at any time if you steerslightly in the opposite direction.DISTRONIC PLUS with Steering Assist andStop&Go Pilot cannot continuously keep yourvehicle in lane. In some cases, the steeringintervention is not sufficient to bring the vehi-cle back to the lane. In such cases, you muststeer the vehicle yourself to ensure that itdoes not leave the lane.

PARKTRONIC

Important safety notesPARKTRONIC is an electronic parking aid withultrasonic sensors. It monitors the areaaround your vehicle using six sensors in thefront bumper and six sensors in the rearbumper. PARKTRONIC indicates visually andaudibly the distance between your vehicleand an object.PARKTRONIC is only an aid. It is not a replace-ment for your attention to your immediatesurroundings. You are always responsible forsafe maneuvering, parking and exiting a park-ing space. When maneuvering, parking orpulling out of a parking space, make sure thatthere are no persons, animals or objects inthe area in which you are maneuvering.

! When parking, pay particular attention toobjects above or below the sensors, suchas flower pots or trailer drawbars.PARKTRONIC does not detect such objectswhen they are in the immediate vicinity of

the vehicle. You could damage the vehicleor the objects.The sensorsmay not detect snow and otherobjects that absorb ultrasonic waves.Ultrasonic sources such as an automaticcar wash, the compressed-air brakes on atruck or a pneumatic drill could causePARKTRONIC to malfunction.PARKTRONICmay not function correctly onuneven terrain.

PARKTRONIC is activated automatically whenyou:Rswitch on the ignitionRshift the transmission to position D, R or NPARKTRONIC is deactivated at speeds above11 mph (18 km/h). It is reactivated at lowerspeeds.

Active Parking Assist

General notesActive Parking Assist is an electronic parkingaid with ultrasound. It measures the road onboth sides of the vehicle. A parking symbolindicates a suitable parking space. Activesteering intervention and brake applicationcan assist you during parking and when exit-ing a parking space. You may also usePARKTRONIC (Y page 195).

Important safety notesActive Parking Assist is merely an aid. It is nota replacement for your attention to yourimmediate surroundings. You are alwaysresponsible for safe maneuvering, parkingand exiting a parking space. Make sure thatno persons, animals or objects are in themaneuvering range.When PARKTRONIC is switched off, ActiveParking Assist is also unavailable.

G WARNINGWhile parking or pulling out of a parkingspace, the vehicle swings out and can driveonto areas of the oncoming lane. This couldresult in a collision with another road user.There is a risk of an accident.Pay attention to other road users. Stop thevehicle if necessary or cancel the Active Park-ing Assist parking procedure.

! If unavoidable, you should drive overobstacles such as curbs slowly and not at asharp angle. Otherwise, you may damagethe wheels or tires.

Active Parking Assist may possibly indicateparking spaces which are not suitable forparking, for example:Rwhere parking or stopping is prohibitedRin front of driveways or entrances and exitsRon unsuitable surfaces

Detecting parking spacesObjects located above the height range ofActive Parking Assist will not be detectedwhen the parking space is measured. Theseare not taken into account when the parkingprocedure is calculated, e.g. overhangingloads, tail sections or loading ramps of goodsvehicles.

G WARNINGIf there are objects above the detection range:RActive Park Assist may steer too earlyRthe vehicle may not stop in front of theseobjects.

You may cause a collision as a result. There isa risk of an accident.If there are objects above the detection range,stop and deactivate Active Parking Assist.

For further information on the detectionrange (Y page 195).Active Parking Assist does not assist youparking in spaces at right angles to the direc-tion of travel if:Rtwo parking spaces are located directlynext to one anotherRthe parking space is directly next to a lowobstacle such as a low curbRyou park forwardsActive Parking Assist does not assist youparking in spaces that are parallel or at rightangles to the direction of travel if:Rthe parking space is on a curbRthe system reads the parking space asbeing blocked, for example by foliage orgrass paving blocksRthe area is too small for the vehicle tomaneuver intoRthe parking space is bordered by an obsta-cle, e.g. a tree, a post or a trailer

: Detected parking space on the left; Parking symbol= Detected parking space on the rightActive Parking Assist is switched on automat-ically when driving forwards. The system isoperational at speeds of up to approximately22 mph (35 km/h). While in operation, thesystem independently locates and measuresparking spaces on both sides of the vehicle.Active Parking Assist will only detect parkingspaces:Rparallel or at right angles to the direction oftravelRthat are parallel to the direction of traveland at least 59 in (1.5 m) wideRthat are parallel to the direction of traveland at least 39.5 in (1.0m) longer than yourvehicleRthat are at right angles to the direction oftravel and at least 39.5 in (1.0 m) widerthan your vehicle

i Note that Active Parking Assist cannotmeasure the size of a parking space if it is atright angles to the direction of travel. Youwill need to judge whether your vehicle willfit in the parking space.

When driving at speeds below 19 mph(30 km/h), you will see the parking symbol asa status indicator in the instrument cluster.When a parking space has been detected, anarrow towards the right or the left alsoappears. By default, Active Parking Assistonly displays parking spaces on the front-passenger side. Parking spaces on the driv-

er's side are displayed as soon as the turnsignal on the driver's side is activated. Whenparking on the driver's side, this must remainswitched on until you acknowledge the use ofActive Parking Assist by pressing theabutton on the multifunction steering wheel.The system automatically determineswhether the parking space is parallel or atright angles to the direction of travel.A parking space is displayed while you aredriving past it, and until you are approx-imately 50 ft (15 m) away from it.

Driving Assistance PLUS package

General notesThe Active Driving Assistance PLUS packageconsists of DISTRONIC PLUS (Y page 177),Active Blind Spot Assist (Y page 217) andActive Lane Keeping Assist (Y page 220).

Active Blind Spot Assist

General notesActive Blind Spot Assist uses a radar sensorsystem, pointed toward the rear of the vehi-cle, to monitor the area to the sides of thevehicle which the driver is unable to see. Awarning display in the exterior mirrors drawsyour attention to vehicles detected in themonitored area. If you then switch on the cor-responding turn signal to change lanes, youwill also receive a visual and audible collisionwarning. If a risk of lateral collision is detec-

ted, corrective braking may help you avoid acollision. Before a course-correcting brakeapplication, Active Blind Spot Assist evalu-ates the space in the direction of travel and atthe sides of the vehicle. For this, Active BlindSpot Assist uses radar sensors which arepointed in the direction of travel.Active Blind Spot Assist supports you from aspeed of approximately 20 mph (30 km/h).

Important safety notesActive Blind Spot Assist is only an aid and isnot a substitute for attentive driving.

G WARNINGActive Blind Spot Assist does not react to:Rvehicles overtaken too closely on the side,placing them in the blind spot areaRvehicles which approach with a large speeddifferential and overtake your vehicle

Driving systems 217

Followinga severe impact or in the event of damage tothe bumpers, have the function of the radarsensors checked at a qualified specialistworkshop. Active Blind Spot Assist may oth-erwise no longer work properly.

Monitoring areaG WARNINGActive Blind Spot Assist does not detect alltraffic situations and road users. There is arisk of an accident.Always make sure that there is sufficient dis-tance on the side for other traffic or obstacles.

Active Blind Spot Assist monitors the area upto 10 ft (3.0 m) behind your vehicle anddirectly next to your vehicle, as shown in thediagram.The detection of obstacles can be impaired inthe case of:Rthere is dirt on the sensors or anything elsecovering the sensorsRpoor visibility, e.g. due to rain, snow orspray

Vehicles in the monitoring range are then notindicated.Active Blind Spot Assist may not detect nar-row vehicles, such as motorcycles or bicy-cles, or may only detect them too late.If the lanes are narrow, vehicles driving in thelane beyond the lane next to your vehicle maybe indicated, especially if the vehicles are notdriving in themiddle of their lane. This may bethe case if there are vehicles at the inner edgeof your lane.

218 Driving systemsDrivingandparking

Due to the nature of the system:Rwarnings may be issued in error when driv-ing close to crash barriers or similar solidlane borders.Rwarnings may be interrupted when drivingalongside particularly long vehicles, e.g.trucks, for a prolonged time.

Warning display

: Warning displayActive Blind Spot Assist is not operational atspeeds below approximately 20 mph(30 km/h). Vehicles in the monitoring rangeare then not indicated.If a vehicle is detected within the blind spotmonitoring range at speeds above 20 mph(30 km/h), warning lamp: on the corre-sponding side lights up red. This warning isalways emitted when a vehicle enters theblind spot monitoring range from behind orfrom the side. When you overtake a vehicle,the warning only occurs if the difference inspeed is less than 7 mph (12 km/h).If you select the reverse gear, Active BlindSpot Assist is not operational.The brightness of the warning lamps is auto-matically adapted to the brightness of thesurroundings.

When Active Blind Spot Assist is activated,gray radar waves propagating backwardsappear next to the vehicle in the assistancedisplay in the multifunction display. Above aspeed of 20 mph (30 km/h), the color of theradar waves in the assistance displaychanges to green;. Active Blind Spot Assistis then ready for use.

Visual and acoustic collision warningIf you switch on the turn signals to changelanes and a vehicle is detected in the sidemonitoring range, you receive a visual andacoustic collision warning. You will then heara double warning tone and red warninglamp: flashes. If the turn signal remains on,detected vehicles are indicated by the flash-ing of red warning lamp:. There are no fur-ther warning tones.

Course-correcting brake applicationIf Active Blind Spot Assist detects a risk of alateral collision in the monitoring range, acourse-correcting brake application is carriedout. This is meant to assist you in avoiding acollision.

G WARNINGA course-correcting brake application cannotalways prevent a collision. There is a risk of anaccident.Always steer, brake or accelerate yourself,especially if Active Blind Spot Assist warnsyou ormakes a course-correcting brake appli-cation. Always maintain a safe distance at thesides.

G WARNINGActive Lane Keeping Assist cannot alwaysclearly detect lane markings.In such cases, Active Lane Keeping Assistcan:Rgive an unnecessary warning and thenmake a course-correcting brake applicationto the vehicleRnot give a warning or interveneThere is a risk of an accident.Always pay particular attention to the trafficsituation and keep within the lane, especiallyif Active Lane Keeping Assist alerts you. Ter-minate the intervention in a non-critical driv-ing situation.

The systemmay be impaired or may not func-tion if:Rthere is poor visibility, e.g. due to insuffi-cient illumination of the road, or due tosnow, rain, fog or sprayRthere is glare, e.g. from oncoming traffic,the sun or reflections (e.g. when the roadsurface is wet)Rthe windshield is dirty, fogged up, damagedor covered, for instance by a sticker, in thevicinity of the cameraRthe radar sensors in the front or rear bump-ers or the radiator trim are dirty, e.g.obscured by snowRthere are no, several or unclear lane mark-ings for a lane, e.g. in areas with road con-struction workRthe lane markings are worn away, dark orcovered up, e.g. by dirt or snowRthe distance to the vehicle in front is toosmall and the lanemarkings thus cannot bedetectedRthe lane markings change quickly, e.g.lanes branch off, cross one another ormergeRthe road is narrow and windingRthere are strong shadows cast on the road

If no vehicle is detected in the adjacent laneand broken lane markings are detected, nolane-correcting brake application is made.

Warning vibration in the steering wheelA warning may be given if a front wheelpasses over a lanemarking. It will warn you bymeans of intermittent vibration in the steer-ing wheel for up to 1.5 seconds.

Lane-correcting brake applicationIf you leave your lane, under certain circum-stances the vehicle will brake briefly on oneside. This is meant to assist you in bringingthe vehicle back to the original lane.

G WARNINGA lane-correcting brake application cannotalways bring the vehicle back into the originallane. There is a risk of an accident.Always steer, brake or accelerate yourself,especially if Active Lane Keeping Assist warnsyou or makes a lane-correcting brake appli-cation.

If a lane-correcting brake application occurs,display: appears in the multifunction dis-play. The brake application also slightlyreduces vehicle speed.This function is available in the range between40 mph and 120 mph (60 km/h and200 km/h).A lane-correcting brake application can bemade after driving over a lane marking rec-ognized as being solid or broken. Before this,a warning must be given by means of inter-mittent vibration in the steering wheel. In

X Remove coolant, brake fluid, tree resin,oils, fuels and greases by rubbing gentlywith a cloth soaked in petroleum ether orlighter fluid.

X Use tar remover to remove tar stains.X Use silicone remover to remove wax.If water no longer forms "beads" on the paintsurface, use the paint care products recom-mended and approved by Mercedes-Benz.This is the case approximately every three tofive months, depending on the climate con-ditions and the care product used.If dirt has penetrated the paint surface or ifthe paint has become dull, the paint cleanerrecommended and approved by Mercedes-Benz should be used.Do not use these care products in the sun oron the hood while the hood is hot.X Use a suitable touch-up stick, e.g. MBTouch-Up Stick, to repair slight damage tothe paintwork quickly and provisionally.

Matte finish care

! Never polish the vehicle or the light alloywheels. Polishing causes the finish toshine.

! The following may cause the paint tobecome shiny and thus reduce the matteeffect:RVigorous rubbing with unsuitable mate-rials.RFrequent use of car washes.RWashing the vehicle in direct sunlight.

! Never use paint cleaner, buffing or pol-ishing products, or gloss preserver, e.g.wax. These products are only suitable forhigh-gloss surfaces. Their use on vehicleswith matte finish leads to considerable sur-face damage (shiny, spotted areas).Always have paintwork repairs carried outat a qualified specialist workshop.

! Do not use wash programs with a hot waxtreatment under any circumstances.

Observe these notes if your vehicle has aclear matte finish. This will help you to avoiddamage to the paintwork due to incorrecttreatment.These notes also apply to light alloy wheelswith a clear matte finish.The vehicle should preferably be washed byhand using a soft sponge, car shampoo andplenty of water.Use only insect remover and car shampoofrom the range of approved Mercedes-Benzcare products.

MOExtended tires (tires with run-flatproperties)

General notesWith MOExtended tires (tires with run flatcharacteristics), you can continue to driveyour vehicle even if there is a total loss ofpressure in one or more tires. The affectedtiremust not showany clearly visible damage.You can recognize MOExtended tires by theMOExtended marking which appears on thesidewall of the tire. You will find this markingnext to the tire size designation, the load-bearing capacity and the speed index(Y page 371).MOExtended tires may only be used in con-junction with an active tire pressure monitor.

If the pressure loss warning messageappears in the multifunction display:RObserve the instructions in the displaymessages (Y page 273).RCheck the tire for damage.RIf driving on, observe the following notes.The maximum driving distance is approx-imately 50 miles (80 km) when the vehicle ispartially laden and approximately 18 miles(30 km) when the vehicle is fully laden.In addition to the vehicle load, the driving dis-tance possible depends upon:RSpeedRRoad conditionROutside temperatureThe driving distance possible in run-flat modemay be reduced by extreme driving condi-tions/maneuvers, or it can be increasedthrough a moderate style of driving.The maximum permissible distance whichcan be driven in run-flatmode is counted fromthe moment the tire pressure loss warningappears in the multifunction display.You must not exceed a maximum speed of50 mph (80 km/h).

i When replacing one or all tires, make surethat you use only tires:Rof the size specified for the vehicle andRmarked "MOExtended"If a tire has gone flat and cannot bereplaced with a MOExtended tire, a stand-ard tire may be used as a temporary meas-ure. Make sure that you use the proper sizeand type (summer or winter tire).

i Vehicles equippedwithMOExtended tiresare not equipped with a TIREFIT kit at thefactory. It is therefore recommended thatyou additionally equip your vehicle with aTIREFIT kit if you mount tires that do notfeature run-flat properties, e.g. winter tires.A TIREFIT kit may be obtained from a quali-fied specialist workshop.

Operation

Information on drivingIf the vehicle is heavily loaded, check the tirepressures and correct them if necessary.While driving, pay attention to vibrations,noises and unusual handling characteristics,e.g. pulling to one side. This may indicate thatthe wheels or tires are damaged. If you sus-pect that a tire is defective, reduce yourspeed immediately. Stop the vehicle as soonas possible to check the wheels and tires fordamage. Hidden tire damage could also becausing the unusual handling characteristics.If you find no signs of damage, have the tiresand wheels checked at a qualified specialistworkshop.

356 OperationWheelsandtires

When parking your vehicle, make sure thatthe tires do not get deformed by the curb orother obstacles. If it is necessary to drive overcurbs, speed humps or similar elevations, tryto do so slowly and at an obtuse angle. Oth-erwise, the tires, particularly the sidewalls,may be damaged.

Regular checking of wheels and tires

G WARNINGDamaged tires can cause tire inflation pres-sure loss. As a result, you could lose control ofyour vehicle. There is a risk of accident.Check the tires regularly for signs of damageand replace any damaged tires immediately.

Regularly check the wheels and tires of yourvehicle for damage at least once a month, aswell as after driving off-road or on roughroads. Damaged wheels can cause a loss oftire pressure. Pay particular attention to dam-age such as:Rcuts in the tiresRpuncturesRtears in the tiresRbulges on tiresRdeformation or severe corrosion on wheelsRegularly check the tire tread depth and thecondition of the tread across the whole widthof the tire (Y page 357). If necessary, turn thefront wheels to full lock in order to inspect theinner side of the tire surface.All wheels must have a valve cap to protectthe valve against dirt and moisture. Do notmount anything onto the valve other than thestandard valve cap or other valve capsapproved by Mercedes-Benz for your vehicle.Do not use any other valve caps or systems,e.g. tire pressure monitoring systems.Regularly check the pressure of all the tiresparticularly prior to long trips. Adjust the tirepressure as necessary (Y page 359).

The service life of tires depends, among otherthings, on the following factors:RDriving styleRTire pressureRDistance covered

Notes on tire tread

G WARNINGInsufficient tire tread will reduce tire traction.The tire is no longer able to dissipate water.This means that on wet road surfaces, the riskof hydroplaning increases, in particular wherespeed is not adapted to suit the driving con-ditions. There is a risk of accident.If the tire pressure is too high or too low, tiresmay exhibit different levels of wear at differ-ent locations on the tire tread. Thus, youshould regularly check the tread depth andthe condition of the tread across the entirewidth of all tires.Minimum tire tread depth for:RSummer tires:â in (3 mm)RM+S tires:ã in (4 mm)For safety reasons, replace the tires beforethe legally prescribed limit for the minimumtire tread depth is reached.

Bar indicator: for tread wear is integratedinto the tire tread.Treadwear indicators (TWI) are required bylaw. Six indicators are positioned on the tiretread. They are visible once a tread depth ofapproximatelyá in (1.6 mm) has been

reached. If this is the case, the tire is so wornthat it must be replaced.

Selecting, mounting and replacingtiresROnly mount tires and wheels of the sametype and make.Exception: it is permissible to install a dif-ferent type or make in the event of a flattire. Observe the "MOExtended tires (tireswith run-flat characteristics" section(Y page 337).ROnly mount tires of the correct size ontothe wheels.RBreak in new tires at moderate speeds forthe first 60miles (100 km). They only reachtheir full performance after this distance.RDo not drive with tires which have too littletread depth, as this significantly reducesthe traction on wet roads (hydroplaning).RReplace the tires after six years at the lat-est, regardless of wear.

MOExtended tires (tires with run-flatproperties)With MOExtended tires (tires with run flatcharacteristics), you can continue to driveyour vehicle even if there is a total loss ofpressure in one or more tires.MOExtended tires may only be used in con-junction with an active tire pressure monitorand only on wheels specifically tested byMercedes-Benz.Notes on driving with MOExtended tires witha flat tire (Y page 337).

i Vehicles equippedwithMOExtended tiresare not equipped with a TIREFIT kit at thefactory. It is therefore recommended thatyou additionally equip your vehicle with aTIREFIT kit if you mount tires that do notfeature run-flat properties, e.g. winter tires.A TIREFIT kit can be obtained from a quali-fied specialist workshop.

Winter operation

General notesHave your vehicle winterproofed at a qualifiedspecialist workshop at the onset of winter.Observe the notes in the "Changing a wheel"section (Y page 377).

Driving with summer tiresAt temperatures below 45‡ (+7†), summertires lose elasticity and therefore traction andbraking power. Change the tires on your vehi-cle to M+S tires. Using summer tires at verycold temperatures could cause cracks toform, thereby damaging the tires perma-nently. Mercedes-Benz cannot acceptresponsibility for this type of damage.

G WARNINGDamaged tires can cause tire inflation pres-sure loss. As a result, you could lose control ofyour vehicle. There is a risk of accident.Check the tires regularly for signs of damageand replace any damaged tires immediately.

M+S tires

G WARNINGM+S tires with a tire tread depth of less thanã in (4 mm) are not suitable for use in winterand do not provide sufficient traction. There isa risk of an accident.M+S tires with a tread depth of less thanã in(4 mm) must be replaced immediately.

At temperatures below 45‡ (+7†), use win-ter tires or all-season tires. Both types of tireare identified by the M+S marking.Only winter tires bearing thei snowflakesymbol in addition to the M+S marking pro-vide the best possible grip in wintry road con-ditions. Only these tires will allow drivingsafety systems such as ABS and ESP® tofunction optimally in winter. These tires have

358 Winter operationWheelsandtires

been developed specifically for driving insnow.UseM+S tires of the samemake and tread onall wheels to maintain safe handling charac-teristics.Always observe the maximum permissiblespeed specified for the M+S tires you havemounted.When you have mounted M+S tires:X Check the tire pressures (Y page 362).X Restart the tire pressure monitor(Y page 365).

Snow chains

G WARNINGIf snow chains are installed to the frontwheels, they may drag against the vehiclebody or chassis components. This couldcause damage to the vehicle or the tires.There is a risk of an accident.To avoid hazardous situations:Rnever install snow chains to the frontwheelsRalways install snow chains in pairs to therear wheels.

For safety reasons, Mercedes-Benz recom-mends that you only use snow chains thathave been specially approved for your vehicleby Mercedes-Benz, or are of a correspondingstandard of quality.If you intend to mount snow chains, pleasebear the following points in mind:RSnow chains may not be mounted on allwheel/tire combinations. Permissiblewheel-tire combinations (Y page 382).ROnly use snow chains when driving onroads completely covered by snow.Remove the snow chains as soon as possi-ble when you come to a road that is notsnow-covered.

RLocal regulations may restrict the use ofsnow chains. Observe the appropriate reg-ulations if you wish to mount snow chains.RDo not exceed the maximum permissiblespeed of 30 mph (50 km/h).ROn vehicles with AIRMATIC (Y page 192) orActive Body Control (ABC) (Y page 190),you must drive at raised vehicle level ifsnow chains have been installed.

You may wish to deactivate ESP® (Y page 72)when pulling awaywith snow chains installed.You can thereby allow the wheels to spin in acontrolled manner, achieving an increaseddriving force (cutting action).

Tire pressure

Important safety notes

G WARNINGUnderinflated or overinflated tires pose thefollowing risks:Rthe tires may burst, especially as the loadand vehicle speed increase.Rthe tires may wear excessively and/orunevenly, which may greatly impair tiretraction.Rthe driving characteristics, as well as steer-ing and braking, may be greatly impaired.

There is a risk of an accident.Follow recommended tire inflation pressuresand check the pressure of all the tires includ-ing the spare wheel:Rmonthly, at leastRif the load changesRbefore beginning a long journeyRunder different operating conditions, e.g.off-road driving

If necessary, correct the tire pressure.

specifications are vehicle-specific and maydeviate from the data shown here. The tirepressure specifications that are valid foryour vehicle can be found on the Tire andLoading Information placard and tire pres-sure table on the vehicle.

General notesThe recommended tire pressures for the tiresmounted at the factory can be found on thelabels described here.Further information on tire pressures can beobtained at a qualified specialist workshop.

Tire and Loading Information placard

: Recommended tire pressuresThe Tire and Loading Information placard ison the B-pillar on the driver's side(Y page 366).The Tire and Loading Information placard con-tains the recommended tire pressures forcold tires. The recommended tire pressuresare valid for the maximum permissible loadand up to the maximum permissible vehiclespeed.

Tire pressure tableThe tire pressure table is on the inside of thefuel filler flap.

Example: tire pressure table for all tires permittedfor this vehicle by the factory

The tire pressure table contains the recom-mended pressures for cold tires for variousoperating conditions, i.e. differing load andspeed conditions.

Example: tire pressure table with tire dimensions

If a tire size precedes a tire pressure, the tirepressure information following is only validfor that tire size. The load conditions "partiallyladen" and "fully laden" are defined in thetable for different numbers of occupants andamounts of luggage. The actual number ofseats may differ.

360 Tire pressureWheelsandtires

Some tire pressure tables show only the rimdiameters instead of the full tire size, e.g.R18. The rim diameter is part of the tire sizeand can be found on the tire sidewall(Y page 371).If the tire pressures have been set to thelower values for lighter loads and/or lowerroad speeds, the pressures should be reset tothe higher values:Rif you want to drive with an increased loadand/orRif you want to drive at higher road speeds

i The tire pressures for increased loadsand/or higher road speeds, shown in thetire pressure table, may have a negativeeffect on driving comfort.

If the tire pressure is not set correctly, thiscan lead to an excessive build up of heat anda sudden loss of pressure.Formore information, contact a qualified spe-cialist workshop.

Important notes on tire pressure

G WARNINGIf the tire pressure drops repeatedly, thewheel, valve or tire may be damaged. Tirepressure that is too low may result in a tireblow-out. There is a risk of an accident.RCheck the tire for foreign objects.RCheck whether the wheel is losing air or thevalve is leaking.

If you are unable to rectify the damage, con-tact a qualified specialist workshop.

G WARNINGIf you fit unsuitable accessories onto tirevalves, the tire valves may be overloaded andmalfunction, which can cause tire pressureloss. Due to their design, retrofitted tire pres-sure monitors keep the tire valve open. Thiscan also result in tire pressure loss. There is arisk of an accident.

Only screw the standard valve cap or othervalve caps approved by Mercedes-Benz foryour vehicle onto the tire valve.

Use a suitable pressure gauge to check thetire pressure. The outer appearance of a tiredoes not permit any reliable conclusion aboutthe tire pressure. On vehicles equipped withthe electronic tire pressure monitor, the tirepressure can be checked in the on-boardcomputer.The tire temperature and pressure increasewhen the vehicle is in motion. This is depend-ent on the driving speed and the load.Therefore, you should only correct tire pres-sures when the tires are cold.The tires are cold:Rif the vehicle has been parked withoutdirect sunlight on the tires for at least threehours andRif the vehicle has not been driven furtherthan 1 mile (1.6 km)

The tire temperature changes depending onthe outside temperature, the vehicle speedand the tire load. If the tire temperaturechanges by 18 ‡ (10 †), the tire pressurechanges by approximately 10 kPa (0.1 bar/1.5 psi). Take this into account when check-ing the pressure of warm tires. Only correctthe tire pressure if it is too low for the currentoperating conditions. If you check the tirepressure when the tires are warm, the result-ing value will be higher than if the tires werecold. This is normal. Do not reduce the tirepressure to the value specified for cold tires.The tire pressure would otherwise be too low.Observe the recommended tire pressures forcold tires:Ron the Tire and Loading Information placardon the B-pillar on the driver's sideRin the tire pressure table on the inside of thefuel filler flap

Underinflated or overinflated tires

Underinflated tires

G WARNINGTires with pressure that is too low can over-heat and burst as a consequence. In addition,they also suffer from excessive and/or irreg-ular wear, which can severely impair the brak-ing properties and the driving characteristics.There is a risk of an accident.Avoid tire pressures that are too low in all thetires, including the spare wheel.

Underinflated tires may:Roverheat, leading to tire defectsRadversely affect handlingRwear excessively and/or unevenlyRhave an adverse effect on fuel consumption

Overinflated tires

G WARNINGTires with excessively high pressure can burstbecause they are damaged more easily byroad debris, potholes etc. In addition, theyalso suffer from irregular wear, which canseverely impair the braking properties and thedriving characteristics. There is a risk of anaccident.Avoid tire pressures that are too high in all thetires, including the spare wheel.

Overinflated tires may:Rincrease the braking distanceRadversely affect handlingRwear excessively and/or unevenlyRhave an adverse effect on ride comfortRbe more susceptible to damage

Maximum tire pressures

: Example: maximum permissible tire pres-sure

Never exceed the maximum permissible tireinflation pressure. Always observe the rec-ommended tire pressure for your vehiclewhen adjusting the tire pressure(Y page 359).

i The actual values for tires are vehicle-specific and may deviate from the values inthe illustration.

Checking the tire pressures

Checking tire pressures manuallyTo determine and set the correct tire pres-sure, proceed as follows:X Remove the valve cap of the tire that is tobe checked.

X Press the tire pressure gauge securely ontothe valve.

362 Tire pressureWheelsandtires

X Read the tire pressure and compare it withthe recommended value on the Tire andLoading Information placard (Y page 359).

X If the tire pressure is too low, increase it tothe recommended value.

X If the tire pressure is too high, release air bypressing down the metal pin in the valve.Use the tip of a pen, for example. Then,check the tire pressure again using the tirepressure gauge.

X Screw the valve cap onto the valve.X Repeat these steps for the other tires.

Tire pressure monitor

General notesIf a tire pressuremonitor is installed, the vehi-cle's wheels have sensors that monitor thetire pressures in all four tires. The tire pres-sure monitor warns you if the pressure dropsin one or more of the tires. The tire pressuremonitor only functions if the correspondingsensors are installed in all wheels.Information on tire pressures is displayed inthe multifunction display. After a fewminutesof driving, the current tire pressure of eachtire is shown in the ServiceServicemenu of the mul-tifunction display; see illustration (example).

For information on the message display, referto the "Checking the tire pressure electroni-cally" section (Y page 364).

Important safety notes

G WARNINGEach tire, including the spare (if provided),should be checked at least once every twoweeks when cold and inflated to the pressurerecommended by the vehicle manufactureron the Tire and Loading Information placardon the driver's door B-pillar or the tire pres-sure label on the inside of the fuel filler flap. Ifyour vehicle has tires of a different size thanthe size indicated on the Tire and LoadingInformation placard or, if available, the tirepressure label, you should determine theproper tire pressure for those tires.As an added safety feature, your vehicle hasbeen equippedwith a tire pressuremonitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tiresare significantly underinflated. Accordingly,when the low tire pressure telltale lights up,you should stop and check your tires as soonas possible, and inflate them to the properpressure. Driving on a significantly underin-flated tire causes the tire to overheat and canlead to tire failure.Underinflation also reduces fuel efficiencyand tire tread life, andmay affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tiremaintenance, and it is the driver's responsi-bility to maintain correct tire pressure, even ifunderinflation has not reached the level totrigger illumination of the TPMS low tire pres-sure telltale.Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the sys-tem detects a malfunction, the warning lampwill flash for approximately a minute and thenremain continuously illuminated. Thissequencewill be repeated every time the vehi-cle is started as long as the malfunctionexists. When the malfunction indicator is illu-

minated, the systemmay not be able to detector signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation of incom-patible replacement or alternate tires orwheels on the vehicle that prevent the TPMSfrom functioning properly. Always check theTPMS malfunction telltale after replacing oneor more tires or wheels on your vehicle toensure that the replacement or alternate Tiresand wheels allow the TPMS to continue tofunction properly.

It is the driver's responsibility to set the tirepressure to that recommended for cold tireswhich is suitable for the operating situation(Y page 359). Note that the correct tire pres-sure for the current operating situation mustfirst be taught-in to the tire pressure monitor.If there is a substantial loss of pressure, thewarning threshold for the warning message isaligned to the reference values taught-in.Restart the tire pressuremonitor after adjust-ing the pressure of the cold tires(Y page 365). The current pressures aresaved as new reference values. As a result, awarning message will appear if the tire pres-sure drops significantly.The tire pressure monitor does not warn youof an incorrectly set tire pressure. Observethe notes on the recommended tire pressure(Y page 359).The tire pressure monitor is not able to warnyou of a sudden loss of pressure, e.g. if thetire is penetrated by a foreign object. In theevent of a sudden loss of pressure, bring thevehicle to a halt by braking carefully. Avoidabrupt steering maneuvers.The tire pressure monitor has a yellow warn-ing lamp in the instrument cluster for indicat-ing a pressure loss or malfunction. Whetherthe warning lamp flashes or lights up indi-cates whether a tire pressure is too low or thetire pressure monitor is malfunctioning:Rif the warning lamp is lit continuously, thetire pressure on one or more tires is signif-

icantly too low. The tire pressure monitor isnot malfunctioning.Rif the warning lamp flashes for around aminute and then remains lit constantly, thetire pressure monitor is malfunctioning.

i In addition to the warning lamp, a mes-sage appears in the multifunction display.You can find further information under:(Y page 273).

If the tire pressure monitor is malfunctioning,it may take up to ten minutes for the tirepressure warning lamp to inform you of themalfunction by flashing for approximately oneminute and then remaining lit. When the mal-function has been rectified, the tire pressurewarning lamp goes out after a few minutes ofdriving.The tire pressure values indicated by the on-board computer may differ from those meas-ured at a gas station with a pressure gauge.The tire pressures shown by the on-boardcomputer refer to those measured at sealevel. At high altitudes, the tire pressure val-ues indicated by a pressure gauge are higherthan those shown by the on-board computer.In this case, do not reduce the tire pressures.The operation of the tire pressuremonitor canbe affected by interference from radio trans-mitting equipment (e.g. radio headphones,two-way radios) that may be being operatedin or near the vehicle.

Instruction labels for tires and loads

G WARNINGOverloaded tires can overheat, causing ablowout. Overloaded tires can also impair thesteering and driving characteristics and leadto brake failure. There is a risk of accident.Observe the load rating of the tires. The loadrating must be at least half of the GAWR of

your vehicle. Never overload the tires byexceeding the maximum load.

Two instruction labels on your vehicle showthe maximum possible load.(1) The Tire and Loading Information placard

is on the B-pillar on the driver's side. TheTire and Loading Information placardshows themaximum permissible numberof occupants and the maximum permis-sible vehicle load. It also contains detailsof the tire sizes and corresponding pres-sures for tires mounted at the factory.

(2) The vehicle identification plate is on theB-pillar on the driver's side. The vehicleidentification plate informs you of thegross vehicle weight rating. It is made upof the vehicle weight, all vehicle occu-pants, the fuel and the cargo. You canalso find information about themaximumgross axle weight rating on the front andrear axle.The maximum gross axle weight rating isthe maximum weight that can be carriedby one axle (front or rear axle). Neverexceed the maximum load or the maxi-mum gross axle weight rating for thefront or rear axle.

Maximum permissible gross vehicleweight rating

X Specification for maximum gross vehicleweight: is listed in the Tire and LoadingInformation placard: "The combined weightof occupants and cargo should neverexceed XXX kilograms or XXX lbs."

The gross weight of all vehicle occupants,load and luggage must not exceed the speci-fied value.

i The specifications shown on the Tire andLoading Information placard in the illustra-tion are examples. The maximum permis-sible gross vehicle weight rating is vehicle-specific and may differ from that in theillustration. You can find the validmaximumpermissible gross vehicle weight rating foryour vehicle on the Tire and Loading Infor-mation placard.

Number of seats

Maximum number of seats: indicates themaximum number of occupants allowed to

travel in the vehicle. This information can befound on the Tire and Loading Informationplacard.

Determining the correct load limit

Step-by-step instructionsThe following steps have been developed asrequired of all manufacturers under Title 49,Code of U.S. Federal Regulations, Part 575pursuant to the "National Traffic and MotorVehicle Safety Act of 1966".X Step 1: Locate the statement "The com-bined weight of occupants and cargoshould never exceed XXX kg or XXX lbs." onyour vehicle’s Tire and Loading Informationplacard.

X Step 2: Determine the combined weight ofthe driver and passengers that will be ridingin your vehicle.

X Step 3: Subtract the combined weight ofthe driver and passengers from XXX kilo-grams or XXX lbs.

X Step 4: The resulting figure equals theavailable amount of cargo and luggage loadcapacity. For example, if the "XXX" amountequals 1400 lbs and there will be five150-lb passengers in your vehicle, theamount of available cargo and luggage loadcapacity is 650 lbs (1400 - 750 (5 x 150) =650 lbs).

X Step 5:Determine the combined weight ofluggage and cargo being loaded on thevehicle. That weight may not safely exceedthe available cargo and luggage load capa-city calculated in step 4.

Uniform Tire Quality Grading Stand-ards

Overview of Tire Quality Grading Stand-ards

Uniform Tire Quality Grading Standards areU.S. government specifications. Their pur-pose is to provide drivers with uniform relia-ble information on tire performance data. Tiremanufacturers have to grade tires using threeperformance factors:: treadwear grade,;traction grade and= temperature grade.These regulations do not apply to Canada.Nevertheless, all tires sold in North Americaare provided with the corresponding qualitygrading markings on the sidewall of the tire.Quality grades can be found, where applica-ble, on the tire sidewall between the treadshoulder and maximum tire width.Example:RTreadwear grade: 200RTraction grade: AARTemperature grade: AAll passenger car tires must conform to thestatutory safety requirements in addition tothese grades.

i The actual values for tires are vehicle-specific and may deviate from the values inthe illustration.

TreadwearThe treadwear grade is a comparative ratingbased on thewear rate of the tire when testedunder controlled conditions on a specifiedU.S. government course. For example, a tiregraded 150 would wear one and one-halftimes as well on the government course as atire graded 100.The relative performance of tires dependsupon the actual conditions of their use, how-ever, and may depart significantly from thenorm due to variations in driving habits, ser-vice practices and differences in road char-acteristics and climate conditions.

Traction

G WARNINGThe traction grade assigned to this tire isbased on straight-ahead braking tractiontests, and does not include acceleration, cor-nering, hydroplaning, or peak traction char-acteristics.

! Avoid wheelspin. This can lead to damageto the drive train.

The traction grades – from highest to lowest –are AA, A, B and C. Those grades representthe tire's ability to stop on wet pavement asmeasured under controlled conditions onspecified government test surfaces of asphaltand concrete. A tire marked C may have poortraction performance.The safe speed on a wet, snow covered or icyroad is always lower than on dry road surfa-ces.You should pay special attention to road con-ditions when temperatures are around freez-ing point.Mercedes-Benz recommends a minimumtread depth ofã in (4 mm) on all four wintertires. Observe the legally required minimumtire tread depth (Y page 357).Winter tires canreduce the braking distance on snow-coveredsurfaces in comparison with summer tires.The braking distance is still much further than

370 All about wheels and tiresWheelsandtires

on surfaces that are not icy or covered withsnow. Take appropriate care when driving.Further information on winter tires (M+Stires) (Y page 358).

Temperature

G WARNINGThe temperature grade for this tire is estab-lished for a tire that is properly inflated andnot overloaded. Excessive speed, underinfla-tion, or excessive loading, either separately orin combination, can cause excessive heatbuild-up and possible tire failure.

The temperature grades are A (the highest), B,and C. They represent the tire's resistance tothe generation of heat and its ability to dissi-pate heat when tested under controlled con-ditions on a specified indoor laboratory testwheel. Sustained high temperature can causethe material of the tire to degenerate andreduce tire life, and excessive temperaturecan lead to sudden tire failure. The grade Ccorresponds to a level of performance whichall passenger car tires must meet under theFederal Motor Vehicle Safety Standard No.109. Grades B and A represent higher levelsof performance on the laboratory test wheelthan the minimum required by law.

Speed ratingThe speed rating is part of the tire identifica-tion. It specifies the speed range forwhich thetire is approved.

GVW (Gross Vehicle Weight)The gross vehicle weight includes the weightof the vehicle including fuel, tools, the sparewheel, accessories installed, occupants, lug-gage and the drawbar noseweight, if applica-ble. The gross vehicleweightmust not exceedthe gross vehicle weight rating GVWR asspecified on the vehicle identification plate onthe B-pillar on the driver's side.

GVWR (Gross Vehicle Weight Rating)The GVWR is the maximum permissible grossweight of a fully loaded vehicle (the weight ofthe vehicle including all accessories, occu-pants, fuel, luggage and the drawbar nose-weight, if applicable). The gross vehicleweight rating is specified on the vehicle iden-tification plate on the B-pillar on the driver'sside.

Maximum loaded vehicle weightThe maximum weight is the sum of:Rthe curb weight of the vehicleRthe weight of the accessoriesRthe load limitRthe weight of the factory installed optionalequipment

Kilopascal (kPa)Metric unit for tire pressure. 6.9 kPa corre-sponds to 1 psi. Another unit for tire pressureis bar. 100 kilopascals (kPa) are the equiva-lent of 1 bar.

Load indexIn addition to the load-bearing index, the loadindexmay also be imprinted on the sidewall ofthe tire. This specifies the load-bearing capa-city more precisely.

Curb weightThe weight of a vehicle with standard equip-ment including themaximum capacity of fuel,oil and coolant. It also includes the air-condi-tioning system and optional equipment ifthese are installed in the vehicle, but does notinclude passengers or luggage.

Maximum load ratingThe maximum load rating is the maximumpermissible weight in kilograms or lbs forwhich a tire is approved.

Maximum permissible tire pressureMaximum permissible tire pressure for onetire.

Maximum load on one tireMaximum load on one tire. This is calculatedby dividing themaximum axle load of one axleby two.

PSI (pounds per square inch)A standard unit of measure for tire pressure.

Aspect ratioRelationship between tire height and tirewidth in percent.

Tire pressureThis is pressure inside the tire applying anoutward force to each square inch of the tire'ssurface. The tire pressure is specified inpounds per square inch (psi), in kilopascal(kPa) or in bar. The tire pressure should onlybe corrected when the tires are cold.

Cold tire pressureThe tires are cold:Rif the vehicle has been parked withoutdirect sunlight on the tires for at least threehours andRif the vehicle has not been driven furtherthan 1 mile (1.6 km)

376 All about wheels and tiresWheelsandtires

TreadThe part of the tire that comes into contactwith the road.

BeadThe tire bead ensures that the tire sitssecurely on the wheel. There are several steelwires in the bead to prevent the tire fromcoming loose from the wheel rim.

SidewallThe part of the tire between the tread and thebead.

Weight of optional extrasThe combined weight of those optional extrasthat weigh more than the replaced standardparts and more than 5 lbs (2.3 kg). Theseoptional extras, such as high-performancebrakes, level control, a roof rack or a high-performance battery, are not included in thecurb weight and the weight of the accesso-ries.

TIN (Tire Identification Number)This is a unique identifier which can be usedby a tire manufacturer to identify tires, forexample for a product recall, and thus identifythe purchasers. The TIN is made up of themanufacturer's identity code, tire size, tiretype code and the manufacturing date.

Load bearing indexThe load bearing index (also load index) is acode that contains themaximum load bearingcapacity of a tire.

TractionTraction is the result of friction between thetires and the road surface.

Treadwear indicatorsNarrow bars (tread wear bars) that are dis-tributed over the tire tread. If the tire tread islevel with the bars, the wear limit ofá in(1.6 mm) has been reached.

Occupant distributionThe distribution of occupants in a vehicle attheir designated seating positions.

Total load limitNominal load and luggage load plus 68 kg(150 lbs) multiplied by the number of seats inthe vehicle.

Changing a wheel

Flat tireThe "Breakdown assistance" section(Y page 336) contains information and noteson how to deal with a flat tire. Information ondriving with MOExtended tires in the event ofa flat tire can be found under "MOExtendedtires (tires with run-flat characteristics"(Y page 337).

Rotating the wheels

G WARNINGInterchanging the front and rear wheels mayseverely impair the driving characteristics ifthe wheels or tires have different dimensions.The wheel brakes or suspension componentsmay also be damaged. There is a risk of acci-dent.Rotate front and rearwheels only if thewheelsand tires are of the same dimensions.

! On vehicles equipped with a tire pressuremonitor, electronic components are loca-ted in the wheel.Tire-mounting tools should not be usednear the valve. This could damage the elec-tronic components.Only have tires changed at a qualified spe-cialist workshop.

Always observe the instructions and safetynotes in the "Mounting a wheel" section(Y page 378).The wear patterns on the front and rear tiresdiffer, depending on the operating conditions.

Changing a wheel 377

Wheelsandtires

Z

Rotate the wheels before a clear wear patternhas formed on the tires. Front tires typicallywear more on the shoulders and the rear tiresin the center.If your vehicle's tire configuration allows, youcan rotate the wheels according to the inter-vals in the tire manufacturer's warranty bookin your vehicle documents. If no warrantybook is available, the tires should be rotatedevery 3,000 to 6,000 miles (5,000 to10,000 km), or earlier if tire wear requires.Ensure the direction of rotation ismaintained.Clean the contact surfaces of the wheel andthe brake disc thoroughly every time a wheelis rotated. Check the tire pressure and reac-tivate the tire pressure monitor if necessary(Y page 365).

Direction of rotationTires with a specified direction of rotationhave additional benefits, e.g. if there is a riskof hydroplaning. These advantages can onlybe gained if the tires are installed correspond-ing to the direction of rotation.An arrow on the sidewall of the tire indicatesits correct direction of rotation.

Storing wheelsStorewheels that are not being used in a cool,dry and preferably dark place. Protect thetires from oil, grease, gasoline and diesel.

Do not mix such fuels with the fuel recom-mended for your vehicle. Do not use addi-tives. Otherwise, engine damage mayoccur. This does not include cleaning addi-tives for the removal and prevention of res-idue build-up. Gasoline may only be mixedwith cleaning additives recommended byMercedes-Benz; see "Additives". You canobtain further information from any author-ized Mercedes-Benz Center.

! To ensure the longevity and full perform-ance of the engine, only premium-gradeunleaded gasoline must be used.If standard unleaded gasoline is unavaila-ble and you have to refuel with unleadedgasoline of a lower grade, observe the fol-lowing precautions:ROnly fill the fuel tank to half full with reg-ular unleaded gasoline and fill the restwith premium-grade unleaded gasolineas soon as possible.RDo not drive at the maximum speed.RAvoid sudden acceleration and enginespeeds over 3,000 rpm.

Youwill usually find information about the fuelgrade on the pump. If you cannot find thelabel on the pump, ask the staff for assis-tance.

i For further information, consult a quali-fied specialist workshop or visithttp://www.mbusa.com (USA only).

i E10 fuel contains up to 10% bioethanol.Your vehicle is E10-compatible. You canrefuel your vehicle using E10 fuel.

As a temporarymeasure, if the recommendedfuel is not available, you may also use regularunleaded gasoline with an octane rating of87 AKI/91 RON. This may reduce engine per-formance and increase fuel consumption.Avoid driving at full throttle and sudden accel-eration. Never refuel using fuel with a lowerAKI.Information on refueling (Y page 164).

Additives! Operating the engine with fuel additivesadded later can lead to engine failure. Donot mix fuel additives with fuel. This doesnot include additives for the removal andprevention of residue buildup. gasolinemust only be mixed with additives recom-mended by Mercedes-Benz. Comply withthe instructions for use on the productlabel. More information about recommen-ded additives can be obtained from anyauthorized Mercedes-Benz Center.

Mercedes-Benz recommends that you usebranded fuels that have additives.The quality of the fuel available in some coun-tries may not be sufficient. Residue couldbuild up in the injection system as a result. Insuch cases, and in consultation with anauthorized Mercedes-Benz Center, the gaso-line may be mixed with the cleaning additiverecommended by Mercedes-Benz. You mustobserve the notes and mixing ratios specifiedon the container.

Engine oil

General notes

! Never use engine oil or an oil filter of aspecification other than is necessary to ful-fill the prescribed service intervals. Do notchange the engine oil or oil filter in order toachieve longer replacement intervals thanthose prescribed. You could otherwisecause engine damage or damage to theexhaust gas aftertreatment.Follow the instructions in the service inter-val display regarding the oil change. Other-wise, you may damage the engine and theexhaust gas aftertreatment.

When handling engine oil, observe the impor-tant safety notes on service products(Y page 391).The engine oils are matched to the perform-ance of Mercedes-Benz engines and serviceintervals. You should therefore only use

Additives

! Do not use any additives in the engine oil.This could damage the engine.

Engine oil viscosity

Viscosity describes the flow characteristicsof a fluid. If an engine oil has a high viscosity,this means that it is thick; a low viscositymeans that it is thin.Select an engine oil with an SAE classification(viscosity) suitable for the prevailing outsidetemperatures. The table shows you whichSAE classifications are to be used. The low-temperature characteristics of engine oilscan deteriorate significantly, e.g. as a resultof aging, soot and fuel deposits. It is thereforestrongly recommended that you carry out reg-ular oil changes using an approved engine oilwith the appropriate SAE classification.

Brake fluid

G WARNINGThe brake fluid constantly absorbs moisturefrom the air. This lowers the boiling point ofthe brake fluid. If the boiling point of the brakefluid is too low, vapor pockets may form in thebrake system when the brakes are appliedhard. This would impair braking efficiency.There is a risk of an accident.You should have the brake fluid renewed atthe specified intervals.

Comply with the important safety notes forservice products when handling brake fluid(Y page 391).The brake fluid change intervals can be foundin the Maintenance Booklet.

Coolant

Important safety notes

G WARNINGIf antifreeze comes into contact with hot com-ponents in the engine compartment, it mayignite. There is a risk of fire and injury.Let the engine cool down before you add anti-freeze.Make sure that antifreeze is not spillednext to the filler neck. Thoroughly clean theantifreeze from components before startingthe engine.

! Only add coolant that has been premixedwith the desired antifreeze protection. Youcould otherwise damage the engine.Further information on coolants can befound in the Mercedes-Benz Specificationsfor Service Products, MB BeVo 310.1, e.g.on the Internet athttp://bevo.mercedes-benz.com. Or con-tact a qualified specialist workshop.

! Always use a suitable coolant mixture,even in countries where high temperaturesprevail.Otherwise, the engine cooling system is notsufficiently protected from corrosion andoverheating.

i Have the coolant regularly replaced at aqualified specialist workshop and thereplacement confirmed in theMaintenanceBooklet.

The coolant is a mixture of water and anti-freeze/corrosion inhibitor. It performs thefollowing tasks:Rcorrosion protectionRantifreeze protectionRraising the boiling pointIf the coolant has antifreeze protection downto -35‡ (-37†), the boiling point of the cool-ant during operation is approximately 266 ‡(130 †).The antifreeze/corrosion inhibitor concentra-tion in the engine cooling system should:Rbe at least 50%. This will protect the enginecooling system against freezing down toapproximately -35 ‡ (-37 †).Rnot exceed 55% (antifreeze protectiondown to -49 ‡ [-45 †]). Otherwise, heatwill not be dissipated as effectively.

Mercedes-Benz recommends an antifreeze/corrosion inhibitor concentrate in accord-ance withMB Specifications for Service Products 310.1.

i When the vehicle is first delivered, it is fil-led with a coolant mixture that ensuresadequate antifreeze and corrosion protec-tion.

i The coolant is checked with every main-tenance interval at a qualified specialistworkshop.
