The First 1000 Miles (1500 km)

The more cautiously you treat your vehicle during the break-in period, the more satisfied you will be with its performance later on.Therefore, drive your vehicle during the first 1500 km (1000 miles) at moderate vehicle and engine-speeds.During this period, avoid heavy loads (full throttle driving) and high RPM (no more than 2/3 of maximum permissible speed in eachgear as indicated on the speedometer).

Downshift at proper engine speed!

On vehicles with automatic transmission avoid accelerating by kickdown. It is not recommended to brake the vehicle by manuallyshifting to a lower gear. We recommend to select positions "4" (for model 300 SL), "3" or "2" only at moderate speeds (for hilldriving).After 1500 km (1000 miles) speeds may be gradually increased to the permissible maximum.

Catalytic Converter

Your MERCEDES-BENZ is equippedwith monolithic type catalytic converters,an important element in conjunction withthe O2 sensor to achieve substantialcontrol of the pollutants in the exhaustemissions. Keep your vehicle in properoperating condition by following our re-commended maintenance instructions asoutlined in your Maintenance Booklet.

Caution!

To prevent damage to the catalyticconverters, use only premium unleadedgasoline in this vehicle.

Any noticeable irregularities in engineoperation should be repaired promptly.Otherwise, excessive unburned fuelmay reach the catalytic convertercausing it to overheat.

Warning!

As with any vehicle, do not idle, parkor operate this vehicle in areas wherecombustible materials such as grass,hay or leaves can come into contactwith the hot exhaust system, as thesematerials could be ignited.

15

Starting and Turning off the Engine

Before StartingEngage parking brake and movegearshift lever to neutral (selectorlever position "P" on automatictransmissions).

Turn key in steering lock to position 2.The charge indicator lamp should comeon.

Cold Engine

Turn key in steering lock clockwise tothe stop. Do not depress accelerator.Release key only when the engine isfiring regularly.

Hot Engine

Turn key in steering lock clockwise tothe stop. Do not depress accelerator. Ifthe engine has not fired after approx. 4seconds, depress accelerator andcontinue cranking until the engine isfiring regularly. Release key and backoff accelerator.

At very high coolant temperatures theengine starting time can be shortened ifthe accelerator is depressed slowly atthe beginning of the starting process.

Turning Off

Turn the key in the steering lock toposition 0 only when the vehicle hasstopped moving.

Note:Vehicles with automatic transmission:the key can only be removed with theselector lever in position "P".

If the coolant temperature is very high(e.g. after hard driving on mountainroads), do not shut off the engineimmediately, but allow

it to run for 1 - 2 minutes at increasedidle speed with selector lever in neutralor position "P".

Important

Due to the installed starter non-repeatfeature, the key must be turnedcompletely to the left before attemptingto start the engine again.

Observe the oil pressure gaugeimmediately after starting the engine.In a very cold engine the oil pressurewill rise slowly after the engine hasstarted. Do not speed up the enginebefore pressure is registered on thepressure gauge.

The charge indicator lamp should goout as soon as the engine has started.

In areas where temperaturesfrequently drop below -25°C (-13°F)we recommend that an engine blockheater be installed. Yourauthorized MERCEDES-BENZ dealerwill advise you on this subject.

Driving Instructions

Power Assistance

When the engine is not running, thebrake and steering systems are withoutpower assistance. Under thesecircumstances, a much greater effort isnecessary to stop or steer the vehicle.

Brakes

Caution!

When driving down long and steepgrades, relieve the load on the brakesby shifting into a lower gear (selectorlever position "4" [for model 300 SL],"3", "2" or "B" [for model 500 SL] inthe case of automatic transmission).This helps prevent overheating of thebrakes and reduces brake pad wear. Donot exceed engine speed limits (seepages 78 or 80).

After hard braking, it is advisable todrive on for some time, rather thanimmediately parking, so the air streamwill cool down the brakes faster.

Warning!

After driving in heavy rain for sometime without applying the brakes orthrough water deep enough to wetbrake components, the first brakingaction may be somewhat reducedand increased pedal pressure maybe necessary. Be sure to maintain asafe distance from vehicles in front.

The condition of the parking brakesystem is checked each time the car isin the shop for the requiredmaintenance.

Between maintenance checks, it is agood practice to apply the parkingbrake once or twice while driving atapproximately 50 km/h (30 mph) on adry straight road. Apply parking brakelightly until a slight drag on the wheelsis felt. Keep applying the brake forabout 10 seconds while pulling the re-lease handle out before releasing theparking brake completely. This practicewill keep the parking brake atmaximum efficiency.

Warning!

The stop lamps will not come onwhen applying the parking brakeonly. Perform the procedure in theprevious paragraph only when theroad is clear of other traffic.

Resting your foot on the brake pedalwill cause excessive and prematurewear of the brake pads.

It can also result in the brakesoverheating thereby significantlyreducing their effectiveness. It maynot be possible to stop the car insufficient time to avoid an accident.

All checks and maintenance work onthe brake system should be carried outby an authorized MERCEDES-BENZdealer.

17

If the parking brake is released and thebrake warning lamp in the instrumentcluster stays on, the brake fluid level inthe reservoir is too low.

Brake pad wear or a leak in the systemmay be the reason for low brake fluidin the reservoir.

Have the brake system inspected at anauthorized MERCEDES-BENZ dealerimmediately.

Install only brake pads and brake fluidrecommended by MERCEDES-BENZ.

Warning!

If other than recommended brakepads are installed, the brakingproperties of the vehicle can beaffected to an extent that the safety issubstantially impaired.

Tires

Tread wear indicators (TWI) arerequired by law. These indicators arelocated in six places on the treadcircumference and become visible at adepth of approx. 2 mm (1/16 in), atwhich point the tire is considered wornand should be replaced.

The tread wear indicator appears as asolid band across the tread.

Warning!

Do not allow your tires to wear downtoo far. With less than 3 mm (1/8 in)of tread, the adhesion properties ona wet road are sharply reduced.Depending upon the weather and/orroad surface (conditions), the tiretraction varies widely.

Specified tire pressures must bemaintained. This applies particularly ifthe tires are subjected to high loads(e.g. high speeds, heavy loads, highambient temperatures).

Warning!

Do not drive with a flat tire. A flattire affects the ability to steer orbrake the vehicle. You may losecontrol of the car. Continued drivingwith a flat tire or driving at highspeed with a flat tire will causeexcessive heat build-up and possiblya fire, or tire blowout.

18

Aquaplaning

Depending on the depth of the waterlayer on the road, aquaplaning mayoccur, even at low speeds and with newtires. Avoid track grooves in the roadarid apply brakes cautiously in the rain.

Tire TractionThe safe speed on a wet, snow coveredor icy road is always lower than on adry road.

You should pay particular attention tothe condition of the road as soon as theprevailing temperatures fall close to thefreezing point.

Warning!If ice has formed on the road, tiretraction will be substantiallyreduced. Under such weatherconditions, drive, steer and brakewith extreme caution.

We recommend M + S radial-ply tiresfor the winter season for all fourwheels to insure normal balancedhandling characteristics.

On packed snow, they can reduce yourstopping distance as compared withsummer tires. Stopping distance,however, is still considerably greaterthan when the road is wet or dry.Parking

Warning!

To reduce the risk of personalinjury as a result of vehiclemovement, before turning off theengine and leaving the vehiclealways:

1. Keep foot on brake pedal.2. Firmly depress parking

brake pedal.3. Engage first or reverse gear

(selector lever position "P" inthe case of automatictransmissions).

4. Slowly release brake pedal.5. Turn front wheels towards

the road curb.6. Turn the key to steering

lock position 0 and remove.

Important!

It is advisable to set the parking brakewhenever parking or leaving thevehicle. In addition, engage first orreverse gear (selector lever position"P").When parking on hills, always set theparking brake.

Clutch

Caution!

Resting your foot on the clutchpedal will cause excessive andpremature wear of the clutchcomponents.

19

Winter Driving Instructions

The most important rule for slippery oricy roads is to drive sensibly and toavoid abrupt acceleration, braking andsteering action. Do not use the cruisecontrol system under such conditions.

When the vehicle is in danger ofskidding, declutch, or in case ofautomatic transmission move selectorlever to position "N". Try to keep thevehicle under control by correctivesteering action.

Road salts and chemicals can adverselyaffect braking efficiency. Increasedpedal force may become necessary to

produce the normal brake effect. Wetherefore recommend depressing thebrake pedal repeatedly when travelingon salt-strewn roads at length. This canbring road salt impaired brakingefficiency back to normal. Aprerequisite is, however, that this ispossible without endangering otherdrivers on the road.

If the vehicle is parked after beingdriven on salt treated roads, the brakingefficiency should be tested as soon aspossible after driving is resumed whileobserving the safety rules in theprevious paragraph.

Warning!

If the vehicle becomes stuck in snow,make sure that snow is kept clear ofthe exhaust pipe and from aroundthe vehicle with engine running.Otherwise, deadly carbon monoxide(CO) gases may enter vehicleinterior resulting in unconsciousnessand death.

To assure sufficient fresh airventilation, open a window slightlyon the side of the car that is out ofthe wind.

The automatic climate control removesconsiderable moisture from the airduring operation in the cooling mode.It is normal for water to drip on theground through ducts in the underbody.Outside air is drawn in through a filter.Dust particles (up to a certain size) andpollen are filtered out.

Important!

Inappropriate repair work may causerefrigerant (CFC) to escape into theatmosphere and contribute to thedepletion of the earth's ozone layer.Selected vehicles may be equippedwith an air conditioner system that usesHFC-134a (ozone-friendlyhydrofluorocarbon) as a refrigerant.Repairs should always be performed bya qualified technician, and refrigerantshould be collected in a recoverysystem for recycling.

Seat Belts and SupplementalRestraint System (SRS)

Your vehicle is equipped with lap-shoulder seat belts, emergencytensioning retractors for the seat belts,driver airbag and knee bolster andpassenger airbag and knee bolster.

Seat Belts

Important!

Laws in most states and all Canadianprovinces require seat belt use.All states and provinces require use ofchild restraints that comply with U.S.Federal Motor Vehicle Safety Standard213 and Canadian Motor VehicleSafety Standard 213.1. We stronglyrecommend their use.

Seat Belt Warning System

With the key in steering lockposition 2, an audible warning soundsfor a short time if the driver's seat beltis not fastened.

Warning!

If you are ever in an accident, yourinjuries can be considerably moresevere without your seat belt properlybuckled. Without your seat beltbuckled, you can hit the interior ofthe vehicle or be ejected from it. Youcan be seriously injured or killed.

In the same crash, the possibility forinjury or death is lessened with yourseat belt buckled.

The seat belts provide protectiononly with the backrest locked inplace. If the seat belt warning lampdoes not go put, but is instead lit con-tinuously, then a backrest is notengaged in its lock.

Never ride in a moving vehicle withthe seat back reclined. Sitting in anexcessively reclined position can bedangerous. You could slide under theseat belt in a collision. If you slideunder it, the belt would apply forceat the abdomen or neck. That couldcause serious or even fatal injuries.The seat back and seat belts providethe best restraint when the wearer isin an upright position and belts areproperly positioned on the body.

Fastening of Seat Belts

Pull belt with latch plate (1) acrossshoulder and lap. Push latch plate (1)into buckle (2) until it clicks. The lapbelt should be positioned as low aspossible on your hips and not acrossthe abdomen. Do not twist the belt. Forsafety reasons, avoid adjusting the seator seat back into positions which couldaffect the correct seat belt position.

Press switch (4) to adjust seat belt sothat the shoulder portion is located asclose as possible to the middle of yourshoulder.

The shoulder portion of the seat beltmust be pulled snug and checked forsnugness immediately after engaging itand during driving. Tighten the lapportion to a snug fit by pullingshoulder portion up.

42

Unfastening of Seat Belts

Push in the red button (3) in the beltbuckle (2).Allow the retractor to completelyrewind the seat belt by guiding thelatch plate (1).

Operation:The inertia reel stops the belt fromunwinding during sudden vehiclestops or when quickly pulling on thebelt.The locking function of the reel maybe checked by quickly pulling on thebelt.The emergency tensioning retract-orstighten the fastened seat belts duringfrontal and front-angled impactsexceeding the first threshold of theSRS (see Index).

Note:For cleaning and care of the seat belts,see Upholstery in Index.

43

Warning!

USE SEAT BELTS PROPERLY.

• Each occupant should weartheir seat belt at all times.Together with the "SRS",the seat belt offers the bestconditions for protection ofthe body in case of majorfrontal impact.

• Improperly positioned seat beltsdo not provide maximumprotection and may cause seriousinjuries in case of an accident.

• Never wear the shoulderbelt under your arm, againstyour neck or off your shoulder.In a crash, your bodywould move too far forward.That would increase thechance of head and neckinjuries. The belt would alsoapply too much force to theribs, which could severelyinjure internal organs suchas your liver or spleen.

• Position the lap belt as lowas possible on your hipsand not across theabdomen. If the belt ispositioned across yourabdomen, it could causeserious injuries in a crash.

• Each seat belt should neverbe used for more than oneperson at a time.

• Belts should not be worn twisted.In a crash, you wouldn't have thefull width of the belt to takeimpact forces. The twisted beltagainst your body could causeinjuries.

• Pregnant women should also use alap-shoulder belt. The lap beltportion should be positioned aslow as possible on the hips toavoid any possible pressure onthe abdomen.

USE CHILD RESTRAINTSPROPERLY.

• Infants and small childrenmust be seated in an infantor child restraint system,which is properly securedby a lap belt or lap beltportion of a lap-shoulderbelt. Children could beendangered in an accident iftheir child restraints are notproperly secured in thevehicle.

• Rear-facing child restraints mustnot be used in the front seat witha passenger side airbag. Theycould be struck by the airbagwhen it inflates in a crash. If thishappens, a child in the restraintcould be seriously injured.

• Children too big for childrestraint systems shoulduse regular seat belts.Position shoulder beltacross chest and shoulder,not face or neck. A boosterseat may be necessary toachieve proper belt positioning.

44

Supplemental Restraint System(SRS)

The SRS uses two crash severity levels(thresholds) to activate either the ETRor airbag or both. Activation dependson exceeding the thresholds andfastening of the seat belt.

Seat belt fastened• first threshold exceeded:

ETR activates• second threshold exceeded:

airbag also activates

Seat belt not fastened

• first threshold exceeded: airbagactivates, but not ETR

Driver and front passenger systemsoperate independently from each other.

Emergency TensioningRetractor (ETR)

The seat belts are equipped withemergency tensioning retractors. Thesetensioning retractors are located in eachbelt's inertia reel and becomeoperationally ready with the key insteering lock position 1 or 2.The emergency tensioning retractorsare designed to activate only when theseat belts are fastened during majorfrontal impacts within the shaded areashown. They tighten the belts in such away that they fit more snugly againstthe body, restricting its forwardmovement as much as possible.

In cases of other frontal impacts, roll-overs, certain side impacts, rearcollisions, or other accidents withoutfrontal forces, the emergencytensioning retractors will not beactivated. The driver and passengerwill then be protected by the fastenedseat belts and inertia reel in the usualmanner.

For seat belt and emergency tensioningretractor safety guidelines, see SafetyGuidelines in Index.

45

Airbags

The most effective occupant restraintsystem yet developed for use inproduction vehicles is the three pointseat belt. In some cases, however, theprotective effect of a seat belt can befurther enhanced by an airbag.

The driver airbag (1) is located in thesteering wheel hub. The passengerairbag (2) is located in the dashboardahead of the passenger. In conjunctionwith wearing the seat belts withemergency tensioning retractors (4),they provide increased protection forthe driver and passenger.

The operational readiness of the airbagsystem is verified by the indicatorlamp "SRS" (3) in the instrumentcluster. If no fault is detected, the lampwill go out after approximately 4seconds; after the lamp goes out, thesystem continues to monitor thecomponents and circuitry of the airbagsystem and will indicate a malfunctionby coming on again.

46

The following system components aremonitored or undergo a self-check:crash-sensor, airbag ignition circuits,driver and passenger seat belt buckles.Initially, when the key is turned fromsteering lock position 0 to positions 1 or2, malfunctions in the crash-sensor aredetected and indicated (the "SRS"indicator lamp stays on longer than 4seconds).In the operational mode, after theindicator lamp has gone out followingthe initial check, interruptions and shortcircuits in the airbag ignition circuit andin the driver and passenger seat beltbuckle harnesses, and low voltage in theentire system are detected andindicated.In the event a malfunction of the "SRS"is indicated as outlined above, the"SRS" may not be operational. Westrongly recommend that you visit anauthorized MERCEDES-BENZ dealerimmediately to have the systemchecked; otherwise the "SRS" may notbe activated when needed.

Important!

The airbags are designed to activateonly in certain frontal and front-angled impacts (within the shadedarea shown in the illustration onpage 44). Only during these types ofimpacts will they provide theirsupplemental protection. The driverand passenger should always wearthe seat belts, otherwise it is notpossible for the airbags to providetheir intended supplementalprotection.

In cases of other frontal impacts,roll-overs, certain side impacts, rearcollisions, or other accidents withoutfrontal forces, the airbag will not beactivated. The driver and passengerswill then be protected by the fastenedseat belts.

Important!

The "SRS" is designed to reduce thepotential of injury in certain frontaland front-angled impacts which maycause injuries, however, no systemavailable today can totally eliminateinjuries and fatalities.

The activation of the "SRS"temporarily releases a small amountof dust from the air-bags. This dust,however, is neither injurious to yourhealth, nor does it indicate a fire inthe vehicle.

The service life of the airbagsextends to the date indicated on thelabel located on the driver-side doorlatch post To provide continuedreliability after that date, theyshould be inspected by an authorizedMERCEDES-BENZ dealer at thattime and replaced when necessary.

47

Warning!

It is very important for your safety toalways be in a properly seatedposition and to wear your seat belt.

For maximum protection in the eventof a collision always be in normalseated position with your backagainst the seat back. Fasten yourseat belt and ensure that it isproperly positioned on the body.

Since the airbag inflates withconsiderable speed and force, aproper seating position will keep youin a safe distance from the airbag:

• Sit properly belted in an uprightposition with your back against theseat back.

• Do not lean with your head or chestclose to the steering wheel ordashboard,

• Adjust the passenger as far aspossible rearward from thedashboard, especially when a childrestraint is installed.

• Infants and small children shouldonly be seated in an infant or childrestraint which is properly securedby the seat belt.

• Rear-facing child restrains must notbe used in a front seat with apassenger side airbag .

Failure to follow these instructionscan result in severe injuries to you orother occupants.

48

Safety Guidelines for the Seat Belt,Emergency Tensioning Retractorand Airbag

Warning!• Damaged belts or belts that

were highly stressed in anaccident must be replacedand their anchoring pointsmust also be checked. Useonly belts installed orsupplied by an authorizedMercedes-Benz dealer.

• Do not pass belts oversharp edges.

• Do not make any modificationthat could changethe effectiveness of the belts.

• The "SRS" is designed tofunction on a one-time-onlybasis. An airbag or emergencytensioning retractor(ETR) that was activatedmust be replaced.

• No modifications of anykind may be made to anycomponents or wiring of the"SRS". This includes theinstallation of additional trimmaterial, badges etc. overthe steering wheel hub orfront passenger airbagcover and installation ofadditional electrical/electronicequipment on or near"SRS" components and wiring.

• Several airbag systemcomponents at the steeringwheel get hot after the airbag hasinflated. Don't try to touch them.

• Improper work on the system, including incorrectinstallation and removal,can lead to possible injurythrough an uncontrolledactivation of the "SRS".

• In addition, through improperwork there is the risk ofrendering the "SRS"inoperative. Work on the"SRS" must therefore onlybe performed by an authorizedMercedes-Benz dealer.

• When scrapping the airbagunit or emergency tensioningretractor, it is mandatoryto follow our safety instructions. These instructions areavailable at your authorizedMercedes-Benz dealer.

When you sell the vehicle we stronglyurge you to give notice to the subsequentowner that it is equipped with an "SRS"by alerting him to the applicable sectionin the Owner's Manual.

Infants and Child RestraintSystems

We recommend that all infants andchildren be restrained at all times whilethe vehicle is in motion.

Important!

The use of infant or child restraints isrequired by law in all 50 states and allCanadian provinces.Infants and small children should beseated in an infant or child restraintsystem, which is properly secured bythe lap belt portion of the lap-shoulderbelt, and that complies with U.S.Federal Motor Safety Standard 213 andCanadian Motor Vehicle SafetyStandard 213.1.A statement by the child restraintmanufacturer of compliance with thisstandard can be found on theinstruction label on the restraint and inthe instruction manual provided withthe restraint.When using any infant or childrestraint system, be sure to carefullyread and follow all manufacturer'sinstructions for installation and use.

Warning!

Rear-facing child restraints must notbe used in a front seat with apassenger side airbag. They could bestruck by the airbag when if inflatesin a crash. If this happens, a child inthe restraint could be seriouslyinjured.

Infants and small children shouldnever be held on the lap while thevehicle is in motion. During anaccident they would be almost impos-sible to hold, and could be crushedbetween the adult and the dashboard.

Infants and small children shouldnever share a seat belt with anotheroccupant. During an accident, theycould be crushed between theoccupant and seat belt.

Children too big for child restraintsystems should use regular seat belts.Position the shoulder belt across thechest and shoulder, not the face orneck. A booster seat may benecessary to achieve proper beltpositioning.

When the child restraint is not inuse, remove it from the car orsecure it with the seat belt toprevent the child restraint frombecoming a projectile in the event ofan accident.

U.S.A. Models only

Since 1986 all U.S. child restraintscomply with U.S. regulations withoutthe use of a tether strap.

Driving Off

Test the brakes briefly after driving off.Perform this procedure only when theroad is clear of other traffic.

Warm up the engine smoothly. Do notplace full load on the engine until theoperating temperature has been reached.

Warning!

Keep driver's foot area clear at alltimes. Objects stored in this area mayimpair pedal movement.

77

Manual Transmission

See illustration for gearshift leverpositions corresponding to theindividual gears.

Stop the vehicle completely beforeshifting into reverse; to shift intoreverse, pull the shift lever up.

Do not exceed the maximum speed inthe individual gears. See line markingson the speedometer

Important!

When vehicle is parked, always besure to engage first or reverse gear andfirmly set parking brake

Recommended Shift Points forManual Transmission

For good fuel economy, thefollowing shift points are re-commended:

Shift

from 1 st to 2nd at 15mph(24km/h)

from 2nd to 3rd at 25 mph(40 km/h)

from 3rd to 4th at 40 mph(64 km/h)

from 4th to 5th at 45 mph(72 km/h).

78

Automatic Transmission

The automatic transmissionselects individual gears auto-matically, dependent upon

• Selector lever position• Accelerator position• Vehicle speed

Important!

When parking the car and beforeworking on the vehicle with the enginerunning, firmly depress the parkingbrake pedal and shift the selector leverinto "P".

Driving

The selector lever is automaticallylocked while in position "P". To movethe selector lever out of position "P",the service brake pedal must be firmlydepressed before the shift lock willrelease.

Shift selector lever to the desiredposition only when the engine is idlingnormally and the service brake isapplied. Do not release the brake untilready to drive. The vehicle mayotherwise start creeping when theselector lever is in drive or reverseposition.

Warning!

It is dangerous to shift the selectorlever out of "P" or "N" if the enginespeed is higher than idle speed, ifyour foot is not on the brake pedal,the car could accelerate quicklyforward or in reverse. You could losecontrol of the car and hit someone orsomething. Only shift into gear whenthe engine is idling normally andwhen your right foot is firmly on thebrake pedal.

Accelerator position

Partial throttle= early upshifting= normal acceleration

Full throttle= later upshifting= rapid acceleration

Kickdown (depressing the acceleratorbeyond full throttle)= downshifting to next lowest gear= maximum acceleration.Once the desired speed is attained,ease up on the accelerator - thetransmission shifts up again.

79

Selector Lever Positions 300 SL

The automatic gear shiftingprocess can be adapted tospecific operating conditionsusing the selector lever.

P Parking lock.The parking lock is an additionalsafeguard to the parking brake whenparking the vehicle. Engage onlywith the car stopped.

Note:The key can be removed from thesteering lock only with theselector lever in position "P".

With the key removed, theselector lever is locked inposition "P".

R Reverse gear.Shift to reverse gear only with thecar stopped.

N Neutral.No power is transmitted from theengine to the rear axle. When thebrakes are released, the vehicle canbe moved freely (pushed or towed).Do not engage "N" while drivingexcept to coast when the vehicle isin danger of skidding (e.g. on icyroads, see Winter DrivingInstructions in Index).

Important!

Coasting the vehicle, or driving forany other reason with selector leverin "N", can result in transmissiondamage that is not covered by theMercedes-Benz Limited Warranty.

D The transmission automaticallyupshifts to 5th gear. Position "D"provides optimum drivingcharacteristics under all normaloperating conditions.

4 Upshift to 4th gear only. Suitablefor performance driving.

3 Upshift to 3rd gear only. Suitablefor moderately steep hills. Since thetransmission does not shift higherthan 3rd gear, this gear selectionwill allow use of the engine's brak-ing power downhill.

2 Upshift to 2nd gear only. Fordriving in mountainous regions orunder extreme operating conditions.This gear selection will allow useof the engine's braking power whendescending steep grades.

Important!

With selector lever in position "D","4" or "3", upshifting from 1st to 2ndto 3rd gear is delayed depending onvehicle speed and engine temperature.This allows the catalytic converter toheat up more quickly to operatingtemperatures.During the brief warm-up period thisdelayed upshift and increased enginenoise might be perceived as amalfunction. However, neither theengine nor transmission are negativelyaffected by this mode of operation.

80

Important!

The delayed upshift is effective withvehicle speeds below 31 mph (50km/h) at partial throttle and enginetemperatures below 95°F (35°C).

Do not exceed the vehicle speed limitsfor individual gear selections, whichare indicated by marks (I, II, III etc.) onthe circumference of the speedometer.

To avoid overrevving the engine whenthe selector lever is moved to a lowerdriving range, the transmission will notshift to a lower gear as long as thevehicle speed exceeds the speed limitof that gear.

Warning!

On slippery road surfaces, neverdownshift in order to obtain brakingaction. This could result in rear wheelslip and reduced vehicle control.Your vehicle's ABS will not preventthis type of loss of control.

To prevent the engine from laboring atlow RPMs, do not allow the enginespeed to drop too low on uphillgradients.

Depending on the degree of the incline,shift selector lever to a lower gearrange early enough to maintain engineRPM within the best torque range.

Maneuvering

To maneuver in tight areas, e.g. whenpulling into parking space, control thecar speed by gradually releasing thebrakes. Accelerate gently and neverabruptly step on the accelerator.To rock a car out of soft ground (mudor snow), alternately shift fromforward to reverse, while applyingslight partial throttle.Rocking a car free in this manner maycause the ABS warning lamp to comeon. Turn off and restart the engine toclear the malfunction indication.

Stopping

For brief stops, e.g. at traffic lights,leave the transmission in gear and holdvehicle with the service brake.For longer stops with the engine idling,shift into "N" or "P".When stopping the car on an uphillincline, do not hold it with theaccelerator, use the brake. This avoidsunnecessary transmission heat build up.

Warning!

Getting out of your car with theselector lever not fully engaged inposition "P" is dangerous. Whenparked on a steep incline, position"P" alone may not prevent yourvehicle from moving, possibly hittingpeople or objects.Always set the parking brake inaddition to shifting to position "P".When parked on an incline, also turnfront wheel against curb.

3 Upshift to 3rd gear only. Suitable formoderately steep hills.

2 Upshift to 2nd gear only. Fordriving in mountainous regions.Since the transmission does notshift higher than 2nd gear, this gearselection will allow use of theengine's braking power downhill.

B In this position, the engine'sbraking effect is utilized by shiftinginto 1st gear. Use this positionwhile descending very steep orlengthy downgrades and only atspeeds below 40 mph (60 km/h).

Important!

With selector lever in position "D" or"3", upshifting from 2nd to 3rd gear isdelayed depending on vehicle speedand engine temperature. This allowsthe catalytic converter to heat up morequickly to operating temperatures.During the brief warm-up period thisdelayed upshift and increased enginenoise might be perceived asmalfunction.

Do not brake the vehicle bydownshifting to a lower gear (forexample from "D" to "3") unless thespeedometer needle is below the speedlimit mark of that particular gear range.Overrevving could result in seriousdamage to the engine.

Warning!

On slippery road surfaces, neverdownshift in order to obtain brakingaction. This could result in rear wheelslip and reduced vehicle control.Your vehicle's ABS will not preventthis type of loss of control. Thisapplies particularly for position "B".

To prevent the engine from laboring atlow RPMs, do not allow the enginespeed to drop too low on uphillgradients. Depending on the degree ofthe incline, shift selector lever to alower gear range early enough tomaintain engine RPM within the besttorque range.

Always set the parking brake inaddition to shifting to position "P".

When parked on an incline, also turnfront wheel against curb.

83

Cruise Control

Any given speed above approximately25 mph (40 km/h) can be maintainedwith the cruise control by operating thelever.

1 Accelerate and set:Lift lever briefly to set speed. Holdlever up to accelerate.

2 Decelerate and set:Depress lever briefly to setspeed.Hold lever down to decelerate.

Normally the vehicle is accelerated tothe desired speed with the accelerator.Speed is set by briefly pushing the leverto position 1 or 2. The accelerator canbe released.

The speed can be increased (e.g. forpassing) by using the accelerator. Assoon as the accelerator is released, thepreviously set speed will be resumedautomatically.

If a set speed is to be increased ordecreased slightly, e.g. to adapt to thetraffic flow, hold lever in position 1 or2 until the desired speed is reached, orbriefly tip the control lever in theappropriate direction for increases ordecreases in 0.6 mph (1 km/h)increments. When the lever is released,the newly set speed remains.

3 CancelingTo cancel the cruise control, brieflypush lever to position 3.

When you step on the brake orclutch pedal or the vehicle speeddrops below approx. 25 mph (40km/h), for example when drivingupgrade, the cruise control will becanceled.

If the cruise control cancels by itselfand remains inoperative until theengine is restarted, have the systemchecked at your authorizedMercedes-Benz dealer as soon aspossible.

4 ResumeIf the lever is briefly pushed toposition 4 when driving at a speedexceeding approx. 25 mph (40km/h), the vehicle resumes thespeed which was set prior to thecancellation of the cruise control.The last memorized speed iscanceled when the key in thesteering lock is turned to position 1or 0.

84

Note:If the engine does not brake the vehiclesufficiently while driving on adowngrade, the speed you set on thecruise control may be exceeded andyou may have to step on the brakepedal to slow down. As soon as thegrade eases, the cruise controlled speedwill again be maintained as long as thebrakes were not previously applied, orthe lever may be used to resume thepreviously set speed if the brakes wereapplied.

Warning!

Only use the cruise control if thetraffic and weather conditions makeit advisable to travel at a steadyspeed.

• The use of cruise controlcan be dangerous on windingroads or in heavy trafficbecause conditions do notallow safe driving at asteady speed.

• The use of cruise controlcan be dangerous on slipperyroads. Rapid changesin tire adhesion can resultin wheel spin and loss ofcontrol.

The "Resume" function should onlybe operated if the driver is fullyaware of the previously set speed andwishes to resume this particularpreset speed.

Caution!

In the case of manual transmissions,the vehicle maximum speed in theindividual gears should not beexceeded. See line markings on thespeedometer. In the case of automatictransmissions, the selector lever mustnot be shifted to position "N" whendriving with cruise control engaged asotherwise the engine will overrev,possibly causing serious enginedamage.

85

Charge Indicator Lamp

Should the charge indicator lamp fail tocome on prior to starting when the keyis in steering lock position 2 or shouldit fail to go out after starting or duringoperation, this indicates a fault whichmust be repaired at an authorizedMERCEDES-BENZ dealerimmediately.

If the charge indicator lamp comes onwhile the engine is running, this mayindicate that the poly-V-belt hasbroken. Should this condition occur,the poly-V-belt must be replaced beforecontinuing to operate the vehicle.Otherwise, the engine will overheat dueto an inoperative water pump whichmay result in damage to the engine.

Oil Pressure Gauge withOil Pressure Warning Lamp

With the key in steering lock position2, the oil pressure warning lamp comeson and goes out with the enginerunning.

The oil pressure at idle speed may dropif the engine is at operatingtemperature. This will not jeopardizethe engine's operational reliability.Pressure must, however, riseimmediately upon acceleration.

Note:If the oil pressure warning lamp doesnot go out after starting the engine orcomes on while driving and the oilpressure gauge needle drops to "0",then damage to the engine may occurwith continued operation. Turn offengine immediately and contact anauthorized MERCEDES-BENZ dealer.Do not operate the car until thecondition is repaired.

There is no need for concern should theoil pressure warning lamp light upbriefly, (for example, in sharp turns orhard braking) provided the lamp goesout immediately. We recommend youto drive to the nearest service stationwhere the engine oil should be toppedto the "full" mark on the dipstick withan approved oil.

86

Low Engine Oil Level WarningLamp

With the key in steering lock position2, the oil pressure warning lamp comeson and goes out with the enginerunning.

If the warning lamp comes on with theengine running and at operatingtemperature, the engine oil level hasdropped to approximately theminimum mark on the dipstick.

When this occurs, the warning lampwill first come on intermittently andthen stay on if the oil level dropsfurther.

If no oil leaks are noted and there isindicated engine oil pressure, continueto drive to the nearest service stationwhere the engine oil should be toppedto the "full" mark on the dipstick withan approved oil.

In addition to the warning lamp, theengine oil level should be periodicallychecked with the dipstick, for exampleduring a fuel stop, or before a long trip.See Index.

Engine Oil Consumption

Engine oil consumption checks shouldonly be made after the break-in period.During the break-in period, higher oilconsumption may be noticed and isnormal. Frequent driving at highengine speeds results in increasedconsumption.

Fuel Consumption Gauge

While driving, instantaneous fuelconsumption is indicated in miles pergallon (mpg), or in Canada liters per100 kilometers (I/100 km).

With the engine switched off, theneedle reads "0".

Due to system design, maximumconsumption is indicated at idle speed.

87

Fuel Reserve Warning Lamp

With the key in steering lock position2, the fuel reserve warning lamp comeson and goes out with the enginerunning.

If the warning lamp does not go outafter starting the engine or if it comeson while driving, it indicates that thefuel level is down to the reservequantity of approx. 10 liters (2.6 gal).

Outside Temperature Indicator

The temperature sensor is located in thefront bumper area. Due to its location,the sensor can be affected by road orengine heat during idling or slowdriving. This means that the accuracyof the displayed temperature can onlybe verified by comparison to athermometer placed next to the sensor,not by comparison to external displays(e.g. bank signs, etc.).

Adaptation to ambient temperaturetakes place in steps and depends on theprevailing driving conditions (stop-and-go or moderate, constant driving) andamount of temperature change.

Warning!

The outside temperature indicator isnot designed to serve as an Ice-Warning Device and is therefore un-suitable for that purpose. Indicatedtemperatures just above the freezingpoint do not guarantee that the roadsurface is free of ice.

Coolant Temperature Gauge

If the antifreeze mixture is effective to- 30°C (- 22°F), the boiling point ofthe coolant in the pressurized coolingsystem of your vehicle is approx.130°C (266 °F).

During severe operating conditions andstop-and-go city traffic, the coolanttemperature may rise close to the redmarking.

The engine should not be operated withthe coolant temperature in the red zone.

Warning!

• Driving when your engine is badlyoverheated can cause some fluidswhich may have leaked into theengine compartment to catch fire.You could be seriously burned.Turn off the engine and get out ofthe car until it cools down.

• Steam from an overheated enginecan cause serious burns and canoccur just by opening the enginehood. Stay away from the engine ifyou see or hear steam comingfrom it. Turn off the engine and donot stand near the car until itcools down.

88

Low Engine Coolant LevelWarning Lamp

With the key in steering lock position2, the warning lamp comes on and goesout with the engine running.If the warning lamp does not go outafter starting the engine, or if it comeson while driving, then the coolant levelhas dropped below the required level.If no leaks are noticeable and theengine temperature does not increase,continue to drive to the nearest servicestation and have coolant added to thecoolant system. See page 95.

In cases of major or frequent minorcoolant loss, have the cooling systemchecked at your authorizedMERCEDES-BENZ dealer as soon aspossible.

Note:Do not drive without coolant in thecooling system. The engine canoverheat causing major engine damage.

Monitor the coolant temperature gaugewhile driving.

Warning!

Do not spill antifreeze on hot engineparts. Antifreeze contains ethyleneglycol which may burn if it comesinto contact with hot engine parts.You can be seriously burned.

Low Windshield and HeadlampWasher Fluid Level Warning Lamp

With the key in steering lock position2, the warning lamp comes on and goesout with the engine running.

If the warning lamp comes on with theengine running, the level of thereservoir has dropped to approx.1/4ofthe total volume. The reservoir shouldbe refilled with MB WindshieldWasher Concentrate "S" and water (orcommercially available premixedwindshield washer solvent/antifreeze,depending on ambient temperature -see Index) at the next opportunity. Thereservoir for the windshield andheadlamp washer system is located inthe engine compartment.

Roll Bar Warning Lamp

With the key in steering lock position2, the warning lamp comes on and goesout with the engine running.

Warning!

If the warning lamp does not go outafter starting the engine, or if itcomes on while driving, and theindicator lamps in the roll bar switchblink simultaneously, then the roll barsystem is defective and may notactivate in an accident. In this case,raise the roll bar manually (seeIndex) before continuing to drive.

Have the roll bar system checked atyour authorized Mercedes-Benz dealeras soon as possible.

Seat Belt and Backrest LockWarning Lamp

With the key in steering lock position2, the warning lamp comes on and anaudible warning sounds for a shorttime if the driver's seat belt is notfastened.If a backrest is not engaged in its lock,an audible warning will soundintermittently for up to approx. 20seconds.After starting the engine, the warninglamp blinks for a brief period toremind the driver and passenger tofasten seat belts before driving off.If the warning lamp does not go putafter blinking briefly, but is instead litcontinuously, then a backrest is notengaged in its lock.The warning lamp goes out as soon asthe backrest is engaged in its lock.If the backrest is locked and thewarning lamp does not go out, have thesystem checked at your authorizedMercedes-Benz dealer as soon aspossible.

Exterior Lamp Failure IndicatorLamp

With the key in steering lock position2, a dim indicator lamp comes on, andgoes out with the engine running.

With the key in steering lock position 2or with the engine running, a brightillumination of this lamp indicates anexterior lamp failure (except highmounted stop lamp).

Note:The indicator lamp will also come onif an incorrect bulb is installed.

If additional lighting equipment isinstalled (e.g. auxiliary headlamps etc.)be certain to connect into the fusebefore the failure indicator monitoringunit in order to avoid damaging thesystem.

If an exterior lamp fails, the in-dicator lamp will come on onlywhen that lamp is switched on.

If a brake or turn signal lamp fails, thelamp failure indicator will come onwhen applying the brake or actuatingthe turn signal and stay on until theengine is turned off.

90

Brake Pad Wear Indicator Lamp

The brake pad wear indicator lamp inthe instrument cluster comes on whenthe key in the steering lock is turned toposition 2 and goes out when theengine is running.

If the indicator lamp lights up duringbraking, this indicates that the frontwheel brake pads are worn down.

Have the brake system checked at yourauthorized Mercedes-Benz dealer assoon as possible.

Brake Warning Lamp

The brake warning lamp will come on:

• when there is insufficient brakefluid in the reservoir (enginerunning and parking brake released)

• when the parking brake is set(engine running)

• as a lamp function check (key insteering lock position 2).

When the minimum mark on thereservoir is reached, have the brakesystem checked for brake pad thicknessand leaks.

Warning!

Driving with the brake warninglamp on can result in an accident.Have your brake system checkedimmediately if the brake warninglamp stays on. Don't add brake fluidbefore checking the brake system.Overfilling the brake fluid reservoircan result in spilling brake fluid onhot engine parts and the brake fluidcatching fire. You can be seriouslyburned.

91

Antilock Brake System (ABS)

The ABS prevents the wheels fromlocking up above a vehicle speed ofapproximately 3 km/h (2 mph)independent of road surface conditions.It is necessary, however, that thevehicle speed reaches at least 8 km/h(5 mph) before commencing to brake.

At the instant one of the wheels isabout to lock up, a slight pulsation canbe felt in the brake pedal, indicatingthat the ABS is in the regulating mode.

On slippery road surfaces, the ABS willrespond even with only slight brakepedal pressure. The pulsating brakepedal can be an indication of hazardousroad conditions and functions as areminder to take extra care whiledriving.

The ABS warning lamp in theinstrument cluster comes on with thekey in steering lock position 2 andshould go out with the engine running.

If the charging voltage falls below 10volts, the warning lamp comes on andthe ABS is switched off. When thevoltage is above this value again, thewarning lamp should go out and theABS will be operational.

If the ABS warning lamp does not goout or comes on while driving, itindicates that the ABS has detected amalfunction and has switched off. Inthis case, the brake system functions inthe usual manner, but without antilockassistance.

Have the system checked at yourauthorized Mercedes-Benz dealer assoon as possible.

Warning!

Even the ABS cannot prevent thenatural laws of physics from actingon the vehicle. The ABS cannotprevent accidents, including thoseresulting from excessive speed inturns, following another vehicle tooclosely, or aquaplaning. Only a safe,attentive, and skillful driver canprevent accidents. The capabilities ofan ABS equipped car must never beexploited in a reckless or dangerousmanner which could jeopardize theuser's safety or the safety of others.

92

Acceleration Slip Control (ASR)

The acceleration slip control willengage at all vehicle speeds, if one orboth drive wheels begin to lose tractionand spin. While engaged, the yellowfunction indicator in the speedometerlights up.

With the acceleration slip controlengaged, the brake is applied to thespinning drive wheel until it regainssufficient traction. If both drive wheelslose traction and spin, the brake isapplied to both drive wheels andsimultaneously, engine torque islimited.

As traction on the road surfaceincreases, the allowable engine torquealso increases again and the brake is nolonger applied to drive wheels.

Snow chain switch

Driving with Snow Chains

When driving with snow chains, pressthe upper half of the snow chainswitch, located on the instrumentpanel (the indicator lamp in the switchcomes on) to obtain maximumpossible traction.This mode is effective at speeds up to25 mph (40 km/h). It remains storedin memory up to 37 mph (60 km/h)and automatically engages again whenthe vehicle speed drops below 25 mph(40 km/h).

The mode is canceled in memoryabove 37 mph (60 km/h) and theindicator lamp in the switch goes out.

To switch off: press lower half ofswitch (the indicator lamp in theswitch goes out).

Notes:With the key in steering lock position2, the yellow function indicator lampand the yellow ASR warning lamp inthe instrument cluster come on. Theymust go out with the engine running.

If the ASR warning lamp comes onwith the engine running, amalfunction has been detected.Pressing the accelerator pedal willrequire greater effort. Only 2/3 ofengine output is available.

Have the acceleration slip controlchecked at your authorized Mercedes-Benz dealer as soon as possible.

93

Driving the vehicle with different sizetires will cause the wheels to rotate atdifferent speeds, therefore theacceleration slip control will activate(yellow ASR function indicator lampin instrument cluster comes on). Forthis reason, all wheels, including thespare wheel, must have the same tiresize.

In winter operation, the maximumeffectiveness of the acceleration slipcontrol is only achieved with M + Sradial tires.

On vehicles equipped with accel-eration slip control, the brake pad wearwarning lamp indicates brake pad wearfor the front as well as the rear brakes.

Automatic Locking Differential(ASD)

The automatic locking differentialengages when there is a difference inspeed (slip) between the front and rearwheels of over 1.2 mph (2 km/h) andthe vehicle speed is less than 15.5 mph(25 km/h). It will disengage at speedsabove 26 km/h (16.2 mph).

The yellow function indicator in thespeedometer comes on whenever thereis a difference in speed between thefront and rear wheels of over 2 km/h(1.2 mph), warning of slippery roadconditions.

Note:The automatic locking differential willnot engage at speeds above 25 km/h(15.5 mph). However, above thisspeed, a limited-slip effect of up to35% is always present.

In steering lock position 2, the yellowfunction indicator lamp and the yellowASD warning lamp in the instrumentcluster should come on and then mustgo out with the engine running.

If the ASD warning lamp comes onwith the engine running, a malfunctionhas been detected. We recommend thatyou visit an authorized Mercedes-Benzdealer as soon as possible to have theASD checked.

Notes:When testing the parking brake on abrake test dynamometer, turn off theengine to avoid engaging theautomatic locking differential.

In winter operation, the maximumefficiency of the automatic lockingdifferential can only be attainedthrough the use of M + S radial tires onall four wheels.

94

Adaptive Damping System(ADS)

Depending upon road surfaceconditions, load, driving style, ADSwill automatically adjust the optimalride firmness.

The indicator lamp comes on with thekey in steering lock position 2 and goesout when the engine is running.If the indicator lamp stays on after theengine is running or comes on whiledriving, then the system has detected amalfunction.

We recommend that you visit anauthorized Mercedes-Benz dealer assoon as possible to have the systemchecked-out.

Note:If the battery was disconnected, theindicator lamp will only go out afterthe engine is started and the steeringwheel is turned from full left - to - fullright lock and returned to the centerposition.

Adaptive Damping SystemAdjustment

The switch is located in the centerconsole.Press switchUpper half = firm damping

program.This setting should beused for sporty driving.During the setting forsporty driving theindicator lamp in theswitch lights up.

Lower half =soft dampingprogram.This setting shouldbe used for regulardriving.

95

Emission Control

Certain systems of the engine serve tokeep the toxic components of theexhaust gases within permissible limitsrequired by law.

These systems, of course, will functionproperly only when maintained strictlyaccording to factory specifications.Any adjustments on the engine should,therefore, be carried out only byqualified MERCEDES-BENZtechnicians. Engine adjustments shouldnot be altered in any way. Moreover,the specified service and maintenancejobs must be carried out regularlyaccording to MERCEDES-BENZservicing requirements. For detailsrefer to the Maintenance Booklet.

Warning!

Inhalation of exhaust gas ishazardous to your health. Allexhaust gas contains carbonmonoxide, and inhaling it can causeunconsciousness and lead to death.

Do not run the engine in confinedareas (such as a garage) which arenot properly ventilated. If you thinkthat exhaust gas fumes are enteringthe vehicle while driving, have thecause determined and corrected im-mediately. If you must drive underthese conditions, drive only with atleast one window fully open.

On-Board Diagnostic System(California models only)

The CIS-E control unit monitorsemission control components thateither provide input signals to orreceive output signals from the controlunit. Malfunctions resulting frominterruptions or failure of any of thesecomponents are indicated by the"CHECK ENGINE" indicator lamp inthe instrument cluster and aresimultaneously stored in the CIS-Econtrol unit.

If the "CHECK ENGINE" indicatorlamp comes on, have the systemchecked at your authorized Mercedes-Benz dealer as soon as possible.

An on-board test connection withpushbutton and light emitting diode(LED) is located on the enginecompartment firewall, allowing theaccurate detection of systemmalfunctions.

96

Traveling Abroad

Abroad, there is a widely-spreadMercedes-Benz service network at yourdisposal. If you plan to travel into areaswhich are not listed in the index ofyour dealer directory, you shouldrequest pertinent information from yourauthorized Mercedes-Benz dealer.

Winter Driving

Have your car winterized at yourauthorized Mercedes-Benz dealerbefore the onset of winter.

• Change the engine oil if theengine contains an oil which isnot approved for winter operation.For viscosity (SAE class)and filling quantity, seeCapacities: Fuels, Coolants,Lubricants etc. in Index.

• Check engine coolantanticorrosion/antifreezeconcentration.

• Additive for the windshield washerand headlamp cleaning system: AddMB Concentrate "S" to a premixedwindshield washersolvent/antifreeze which isformulated for below freezingtemperatures (see Index).

• Test battery: Battery capacity dropswith decreasing ambienttemperature. A well charged batteryensures that the engine can alwaysbe started, even at low ambienttemperatures.

• Tires: We recommend M + S radialtires on all four wheels for thewinter season. Observe permissiblemaximum speed for M + S radialtires and the legal speed limit.

Note:In winter operation, the maximumeffectiveness of the acceleration slipcontrol or of the automatic lockingdifferential is only achieved with M +S radial tires.

Snow Chains

Use only snow chains that are testedand recommended by Mercedes-Benz.Your authorized Mercedes-Benz dealerwill be glad to advise you on thissubject.

Chains should only be used on the rearwheels. Follow the manufacturer'smounting instructions.

After driving a short distance,retighten the mounted chains.Snow chains should only be driven onsnow covered roads at speeds not toexceed 30 mph (50 km/h). Removechains as soon as possible when drivingon roads without snow.

For tips on driving on slippery winterroads, refer to Index.

Vehicles with Acceleration Slip Control(ASR):

When driving with snow chains, pressthe snow chain switch, refer to Index.

Practical Hints

98

Hood

To open:To unlock the hood, pull release lever(1) under the driver's side of theinstrument panel.

Pull handle (2) out of radiator grill tostop and open hood. Do not lift hood atlouvers of grill! Make certain thewindshield wiper arm is not foldedforward.

To close:Lower hood and let it drop into lockfrom a height of approx. 30 cm (1 ft).Do not press down on hood with hands.

Warning!

To help prevent personal injury,stay clear of moving parts when thehood is open and the engine isrunning. Be sure the hood isproperly closed before driving.

The engine is equipped with atransistorized ignition system.Because of the high voltage it isdangerous to touch any components(ignition coil, distributor, spark plugsockets, ignition cables, diagnosticsocket) of the ignition system:

• with the engine running,• while starting the engine,• if the ignition is "on" and the

engine is turned manually.

99

Checking Coolant Level

The coolant level can be checkedvisually at the transparent coolantreservoir.To check the coolant level, the vehiclemust be parked on level ground.

Check coolant level only when coolantis cold:

The coolant should reach the rib in thefiller neck. Also see marking (1) onreservoir.

Warning!

• Use extreme caution when openingthe hood if there are any signs ofsteam or coolant leaking from thecooling system.

• Do not remove pressure cap oncoolant reservoir if enginetemperature is above 90°C(194°F). Allow engine to cool downbefore removing cap. The coolantreservoir contains hot fluid and isunder pressure.

• Using a rag, turn cap to first notchto relieve excess pressure. Ifopened immediately, hot scaldingfluid and steam will be blown outunder pressure, possibly causingpersonal injury,

• Do not spill antifreeze on hotengine parts. Antifreeze containsethylene glycol which may burn ifit comes into contact with hotengine parts. You can be seriouslyburned.

Adding Coolant

If coolant has to be added, a 50/50mixture of water and MBanticorrosion / antifreeze should beadded.

300 SL:The drain plugs for the cooling systemare located on the right side of theengine block and" at the bottom of theradiator.

500 SL:The drain plugs for the cooling systemare located on the right and left sidesof the engine block and at the bottomof the radiator.Anticorrosion/antifreeze, seeCoolants in Index.

Checking Engine Oil Level

1 Oil dipstick2 Oil filler cap

500 SL

The best time to check the engineoil level is when the oil is warm, suchas during a fuel stop.

With the vehicle on level ground, stopthe engine and wait a few minutes forthe oil to drain back to the oil pan.

Wipe the dipstick clean beforechecking.

Add oil, if needed, only tothe upper mark (max).Do not overfill engine.

For viscosity and capacity, see"Fuels, Coolants, Lubricants, etc. inIndex.For low engine oil level warning lamp,see Index.

Checking AutomaticTransmission Fluid Level

Dipstick locking lever

1 Release2 Engage

Check transmission fluid level with theengine idling, parking brake engagedand selector lever in position "P". Thevehicle must be parked on level ground.Prior to the check, allow engine to idlefor approx. 1 to 2 minutes.

500 SL

Measure fluid level with the dipstickcompletely inserted and the locking leverreleased (1).

Extreme cleanliness must be observed!To wipe the dipstick, use a clean, lint-free cloth.

To fill the transmission with fluid, pourit through a fine-mesh filter into thedipstick opening. Even the slightestimpurity may cause operational troubles.

The fluid level in the transmission isdependent upon its temperature. Themaximum and minimum fluid levelmarks on the dipstick are applicablereferences only if the transmissionfluid level has reached its normaloperating temperature of 80°C (176°F).

Important!

If the transmission fluid cools down to20 - 30°C (68 - 86°F), which is thenormal shop temperature range, thenthe maximum fluid level will beapproximately 10 mm (0.4 in) belowthe minimum mark on the dipstick. Westress this point because a fluid changeis normally performed when thetransmission fluid has cooled down toshop temperature.

The fluid level must not exceed thedipstick maximum mark with the fluidat operating temperature. Drain orsiphon off excess fluid, if required.

Then push dipstick all the way in andswing locking lever downwards (2).

102

Trunk Lamp

To switch off: Using car key, slideswitch to the left. This prevents thebattery from being discharged if thetrunk is to remain open for an extendedperiod.

When the trunk lid is closed, the switchwill reset and turn on the lamp the nexttime the lid is opened.

Spare Wheel

1 Trunk floor2 Strap

Roll back the floor mat, lift the trunkfloor (1) and engage strap (2) in thehooks on the upper edge of the trunk lid.

First remove the vehicle jack, then thespare wheel; reinstall in reverse order.

First Aid Kit

The first aid kit is located in the lefttrunk well.

103

Vehicle Jack

1 Jack arm2 Jack base3 Tool kit

See illustration for proper storage ofjack.Before storing the jack, the jack arm(1) must be lowered almost to the base(2) of the jack.

Note:First remove the vehicle jack, then thespare wheel; reinstall in reverse order.

Warning!

The jack is designed exclusively forjacking up the vehicle at the jacktubes built into either side of thevehicle. Use the jack only to lift thevehicle during a wheel change.Never get beneath the vehicle whileit is supported by the jack. Keephands and feet away from the areaunder the lifted vehicle. Alwaysfirmly set parking brake and blockwheels before raising vehicle withjack.

Do not disengage parking brakewhile the vehicle is raised. Be certainthat the jack is always vertical whenin use, especially on hills. Lower thevehicle onto sufficient capacityjackstands before working under thevehicle.

Vehicle Tools

The vehicle tools (3) are located belowthe jack.

Wheels

Replace rims or tires with the samedesignation, manufacturer and type asshown on the original part. See yourauthorized Mercedes-Benz dealer forfurther information.

Warning!

Do not mix different tire con-struction types (i.e. radial, bias, andbias-belted) on your car becausehandling may be adversely affectedand may result in loss of control.

See your authorized Mercedes-Benzdealer for information on tested and re-commended rims and tires for summerand winter operation. They can alsooffer advice concerning tire service andpurchase.

104

Tire Replacement

Front tires should be replaced in sets.Furthermore - in the event of tirereplacement - the spare wheel, ifpossible, should be used on the rearaxle. Rims and tires must be of thesame size. For dimensions, see"Technical Data".

We recommend that you break in newtires for approx. 100 km (60 miles) atmoderate speed. It is imperative that thewheel mounting bolts be retightenedafter approx. 100 to 500 km (60 -300miles).

On new vehicles retightening is carriedout during the 1st inspection.Retightening is also necessarywhenever wheels are fitted, e.g. whenthe spare wheel is used for the firsttime or when a set of wheels with M +8 tires is installed.Tightening torque: 110 Nm(80 ft. lb.).

For rim and tire specifications, refer to“Technical Data”.

Warning!

Worn, old tires can cause accidents.If the tire tread is badly worn, or ifthe tires have sustained damage,replace them.

When replacing rims, use onlygenuine MERCEDES-BENZ wheelbolts (identified by Mercedes star)specified for the rim type. Failure todo so can result in the bolts loosen-ing and possibly an accident

Rotating Wheels

The wheels can be rotated according tothe degree of tire wear while retainingthe same direction of travel.

Rotating, however, should be carriedout at a mileage of 5000-10000 km(3000-6000 miles), before the charac-teristic tire wear pattern (shoulder wearon front wheels and tread center wearon rear wheels) becomes visible, asotherwise the driving propertiesdeteriorate.

Note:Thoroughly clean the inner side of thewheels any time you rotate the wheelsor wash the vehicle underside.

The use of retread tires is notrecommended. Retread tires mayadversely affect the handlingcharacteristics and safety of thevehicle.

Dented or bent rims cause tire pressureloss and damage to the tire beads. Forthis reason, check rims for damage atregular intervals.

The rim flanges must be checked forwear before a tire is mounted. Removeburrs, if any.

105

Warning!

The jack is designed exclusively forjacking up the vehicle at the jack tubesbuilt into either side of the vehicle. Usethe jack only to lift the vehicle during awheel change. Never get beneath thevehicle while it is supported by thejack. Keep hands and feet away fromthe area under the lifted vehicle.Always firmly set parking brake andblock wheels before raising vehiclewith jack.

Do not disengage parking brake whilethe vehicle is raised. Be certain that thejack is always vertical when in use,especially on hills. Lower the vehicleonto sufficient capacity jackstandsbefore working under the vehicle.

Changing Wheels

Move vehicle to a level area which is asafe distance from the roadway.

1. Set parking brake and turn onhazard warning flasher.

2. Select 1st or reverse gear in vehicleswith manual transmission orposition "P" in vehicles equippedwith automatic transmission.

3. Prevent vehicle from rolling away byblocking wheels with wheel chocksor sizable wood block or stone (notsupplied with, vehicle). Whenchanging a wheel on a hill, placechocks on the downhill sideblocking both wheels of the otheraxle. On a level road, place onechock in front of and one behind thewheel that is diagonally opposite tothe wheel being changed.

4. Unfold wrench, loosen but do notremove the wheel bolts yet.

106

5. Remove the protective cover fromthe jack support tube opening byinserting a screwdriver in theopening and prying it out.The tube openings are locateddirectly behind the front wheelhousings and in front of the rearwheel housings.

6. Insert jack arm fully into thetube hole up to the stop.Position the jack so that it isalways vertical (plumb-line) asseen from the side (see arrow),even if the vehicle is parked onan incline.

7. Jack up the vehicle until thewheel is clear of the ground.

8. Unscrew wheel bolts completely.Keep bolt threads protected fromdirt and sand.While removing the last bolt,hold wheel against hub to avoidpaint damage on rim.

9. Remove wheel.

10. Screw the alignment bolt (1)supplied in the tool kit into theupper-most threaded hole.

107

11. Install spare wheel on wheelhub. Insert wheel bolts andtighten them slightly.To avoid paint damage, placewheel flat against hub and hold itthere while installing first wheelbolt.Unscrew the alignment bolt toinstall the last wheel bolt.

12. Lower car. Remove jack andinsert jack tube cover.

13. Fold wrench together andtighten the five bolts evenly,following the sequenceillustrated above, until all boltsare tight.Observe a tightening torque of 110Nm (80 ft. lb.).

14. Correct tire pressure.

Important!

When installing new wheels themounting bolts must be retightenedafter approx. 100 to 500 km (60 - 300miles).

Before storing the jack, the jack armmust be lowered almost to the base ofthe jack. Store the spare wheel first andthen the vehicle jack.

Warning!

Incorrect mounting bolts orimproperly tightened mounting boltscan cause the wheel to come off. Thiscould cause an accident Be sure touse the correct mounting bolts.

108

Tire Inflation Pressure

A table (see fuel filler flap) lists the tireinflation pressures specified forsummer and winter tires as well as forthe varying operating conditions.

Important!

Tire pressure differs by approx. 1.5 psi(0.1 bar) per 18°F (10°C) of airtemperature change. Keep this in mindwhen checking tire pressure inside agarage - especially in the winter.

Example:

If garage temperature = approx. + 68 °F (+ 20 ° C) and ambient temperature =approx. + 32° F (0°C) then theadjusted air pressure = specified airpressure + 3 psi (+ 0.2 bar).Tire pressures listed for light loads areminimum values offering high drivingcomfort.Increased inflation pressures for heavyloads produce favorable handlingcharacteristics with lighter loads andare perfectly permissible. The ride ofthe vehicle, however, will becomesomewhat harder.

Tire temperature and pressure increasewith the vehicle speed. Tire pressureshould therefore only be corrected oncold tires. Correct tire pressure in warmtires only if pressure has dropped be-low the pressure listed in the table andthe respective operating conditions aretaken into consideration.An underinflated tire due to a slow leak(e.g. due to a nail in the tire) may causedamage such as tread separation,bulging etc.. Regular tire pressurechecks (including the spare tire) atintervals of no more than 14 days aretherefore essential.If a tire constantly loses air, it shouldbe inspected for damage.

Warning!

Do not overinflate tires.Overinflating tires can result insudden deflation (blowout) becausethey are more likely to becomepunctured or damaged by roaddebris, potholes etc.. Follow recom-mended inflation pressures.Do not overload the tires byexceeding the specified vehiclecapacity weight (as indicated by thelabel on the driver's door latch post).Overloading the tires can overheatthem, possibly causing a blowout.

109

Battery

The maintenance-free battery is locatedin the trunk behind the right-handcover panel.

The service life of the battery isdependent on its condition of charge.The battery should always besufficiently charged to last an optimumlength of time.

Therefore, we recommend that youhave the battery charge checkedfrequently if you use the vehicle mostlyfor short distance trips, or if it is notused for long periods of time.

Only charge a battery with a batterycharger after it has been disconnectedfrom the vehicle electrical circuit.

When removing and connecting thebattery, always make sure that allelectrical consumers are off and thekey is in steering lock position 0.

While the engine is running the batteryterminal clamps must not be loosenedor detached, otherwise the alternatorand other electronic components wouldbe damaged.

Battery Recycling

Batteries contain materials that canharm the environment withimproper disposal.

Large 12 Volt storage batteries containlead, and smaller watch-type batteries(such as in the Infrared Remote ControlUnit) may contain mercury.

Recycling of batteries is thepreferred method of disposal.

Many states require sellers of batteriesto accept old batteries for recycling.

Warning!

Never lean over batteries whileconnecting or jump starting, youmight get injured.

Battery fluid contains sulfuric acid.Do not allow this fluid to come incontact with eyes, skin or clothing.In case it does, immediately flushaffected area with water and seekmedical help.

We recommend that the vehicle betransported using flat bed equipment.This method is preferable to other typesof towing.

The vehicle may be towed with all ofthe wheels on the ground and theselector lever in position "N' / neutralfor distances up to 120 km (75 miles)and at a speed not to exceed 50 km/h(30 mph).

To positively avoid a possibility ofdamage to the transmission, however,we recommend to disconnect the driveshaft at the rear axle drive flange onany towing beyond a short tow to anearby garage.

Do not tow with sling-type equipment.Towing with sling-type equipment overbumpy roads will damage radiator andsupports.The use of wheel lift equipmentwill damage engine oil pan.

Important!

When transporting vehicle on flatbed equipment, the front end ofthe vehicle must be loaded first.Additional ramping may berequired for loading to protectbumper fascia.

Note:With the engine not running, there isno power assistance for the braking andsteering systems. In this case, it isimportant to keep in mind that aconsiderably higher degree of effort isnecessary to brake and steer thevehicle.

To signal turns while being towed withhazard flasher in use, activatecombination switch for left or rightturn signal in usual manner - only theselected turn signal will operate.Upon canceling the turn signal, all fourturn signals will operate again.

Cleaning and Care of the Vehicle

Warning!

Many cleaning products can behazardous. Some are poisonous,others are flammable. Always followthe instructions on the particularcontainer. Always open your car'sdoors or windows when cleaning theinside.

Never use fluids or solvents that arenot designed for cleaning your car.

In operation, your vehicle is subjectedto varying external influences which, ifgone unchecked, can attack the paint-work as well as the underbody andcause lasting damage.

Such damage is caused not only byextreme and varying climaticconditions, but also by air pollution,road salt, tar, gravel and stonechipping. Grease and oil, fuel, coolant,brake fluid, bird droppings, tree resins,etc. should be removed immediately to

avoid paint damage. Frequentwashing, however, reduces and/oreliminates the aggressiveness andpotency of the above adverse in-fluences.

More frequent washings are necessaryto deal with unfavorable conditions; forexample, near the ocean, in industrialareas (smoke, exhaust emissions), orduring winter operation.

You should check your vehicle fromtime to time for stone chipping or otherdamage. Any damage should berepaired as soon as possible to preventthe start of corrosion.

In doing so, do not neglect theunderside of the car. A prerequisite fora thorough check is a washing of theunderbody followed by a thoroughinspection. Damaged areas need to bereundercoated.

Your vehicle has been treated at thefactory with a wax-base rustproofing inthe body cavities which will fast forthe lifetime of the vehicle. Post-production treatment is neithernecessary nor

recommended by Mercedes-Benzbecause of the possibility ofincompatibility between materials usedin the production process and othersapplied later.

We have selected car-care products andcompiled recommendations which arespecially matched to our vehicles andwhich always reflect the latest techno-logy. You can obtain MB car-careproducts at your authorized Mercedes-Benz dealer.

Scratches, corrosive deposits, corrosionor damage due to negligent orincorrect care cannot always beremoved or repaired with the car-careproducts recommended here. In suchcases it is best to seek aid at your au-thorized Mercedes-Benz dealer.

The following topics deal with thecleaning and care of your vehicle andgive important "how-to" informationas well as references to recommendedMB car-care products.

117

Engine Cleaning

Corrosion protection, such as MBAnticorrosion Wax should be appliedto the engine compartment after everyengine cleaning. Before applying, allcontrol linkage bushing should belubricated. The V-belt and all pulleysshould be protected from any wax.

Car Washing

Before washing your vehicle, removeinsect residues, MB Insect Remover isrecommended. Do not use hot water orwash your car in direct sunlight. Useonly a mild car wash detergent, such asMB Autoshampoo.

Thoroughly spray the car with adiffused jet of water. Direct only avery weak spray towards theventilation intake. Use plenty of waterand rinse the sponge and chamoisfrequently.

Rinse with clear water and thoroughlywipe dry with a chamois. Do not allowcleaning agents to dry on the finish.

If the vehicle has been run through anautomatic car wash -in particular oneof the older installations - rewipe therecessed sections in the taillamps(designed to prevent soiling) ifnecessary. No solvents (fuels, thinnersetc.) must be used.

In the winter, thoroughly remove alltraces of road salt as soon as possible.When washing the underbody, do notforget to clean the inner sides of thewheels.

Tar Stains

Quickly remove tar stains before theydry and become more difficult toremove. MB Tar Remover isrecommended.

Window Cleaning

Use a window cleaning solution onvery dirty or oil-stained windows.

Wiper Blade

Clean the wiper blade rubber with aclean cloth and detergent solution.Replace blade twice a year; oncebefore and once after winter.

Headlamp Cleaning System

The condition of the wiper blades isimportant for satisfactory cleaning ofthe headlamp lenses. We thereforerecommend that the blades be inspectedregularly.

Replace damaged wiper blades.

Plastic Parts, Headliner andRubber Part

Do not use oil or wax on these parts.

Seat Belts

The webbing must not be treated withchemical cleaning agents. Use onlyclear, lukewarm water and soap. Donot dry the webbing at temperaturesabove 176°F (8Q°C) or in directsunlight.

Warning!

Do not bleach or dye seat belts as thismay severely weaken them. In acrash they may not be able to provideadequate protection.

118

Instrument Cluster

Use a gentle dish-washing detergent ormild detergent for delicate fabrics as awashing solution. Wipe with a clothmoistened in lukewarm solution. Do notuse scouring agents.

Steering Wheel and Gear Shift Lever

Wipe with a damp cloth and drythoroughly or clean with MB LeatherCleaner.

Upholstery

Using aftermarket seat covers orwearing clothing that have thetendency to give off coloring (e.g.when wet, etc.) may cause theupholstery (velour for example) tobecome permanently discolored. Bylining the seats with a properintermediate cover, contact-dis-coloration will be prevented.Leather Upholstery Wipe leatherupholstery with a damp cloth and drythoroughly or clean with MB LeatherCleaner. Exercise particular care whencleaning perforated leather as itsunderside should not become wet.

Paintwork, Painted BodyComponents

MB-Paint Protector and Sealer shouldbe applied when water drops on thepaint surface do not "bead up";normally in 3 -5 months depending onclimate and washing detergent used.

MB-Paint-Polish should be applied ifpaint surface shows signs of dirtembedding (i.e. loss of gloss).

MB-Fine Polishing Paste must be usedwhen the paint surface shows signs ofexcessive fading/ chalking due to lackof care, etc..

Do not apply any of these products orwax if your car is parked in the sun orif the hood is still hot.

Use the appropriate MB-Touch-UpStick for quick and provisional repairsof minor paint damage (i.e. chips fromstones, car doors, etc.).

Automatic Antenna

For trouble-free operation of theautomatic antenna, we recommend toclean the antenna mast periodically.

Light Alloy Wheels

MB-Autoshampoo should be used forregular cleaning of the light alloywheels.

If possible, clean wheels once a weekwith MB-Autoshampoo, using a softsponge and an ample supply oflukewarm water.

If the MB-Autoshampoo does notsatisfactorily clean the wheels, useMB-Protective Agent for Light AlloyWheels for normal cleaning and MB-Cleaner for Light Alloy Wheels forheavier dirt accumulation.Follow instructions on container.

Ornamental Moldings

For regular cleaning and care of verydirty chrome-plated parts, use achrome cleaner.

119

Soft Top

Clean soft top with soft top raised andlocked. Lower the soft top into thestorage compartment only if the top iscompletely dry. If the top is kept in thestorage compartment for a lengthyperiod, raise it and air it out with thewindows down about every 4 months.

Dry cleaning:

Brush top (always from front to rear)with a soft-bristled brush.

Wet cleaning:

Brush the dry top. Wash with a milddetergent and an ample supply oflukewarm water by wiping with a soft-bristled brush or sponge from front torear. Then rinse thoroughly with clearwater.

If only parts of the top have beenwashed, wet the entire top and allow itto air-dry before lowering it into thestorage compartment.Wipe the rear window with a clothsoaked with a mild, non-abrasivedetergent, rinse and rub dry.Do not use sharp-edged instruments forthe removal of ice and snow.

Note:Never run the vehicle through anautomatic car wash with the soft top inplace as you may damage the soft topmaterial.

Remove bird droppings immediately.The organic acid damages the materialand causes the soft top to leak.

In general, regular spraying orcleansing with clear water is sufficientto keep the top clean.

Wash the top only when heavily soiled,not every time the car iswashed.

Caution!

Never use any gasoline, thinner, tarand stain removers or similar organicsolvents to clean the soft top or plasticwindows.

Engine Oils

Engine oils are specifically tested fortheir suitability in our engines.Therefore, use only engine oilsrecommended by Mercedes-Benz.Information on recommended brands isavailable at your authorized Mercedes-Benz dealer

Air Conditioner Refrigerant

(Selected vehicles -see underhoodlabel).If this vehicle is equipped with an airconditioner system that uses HFC-134a(ozone-friendly hydro-fluorocarbon)refrigerant and special lubricating oil,never use R-12 (CFC) or mineral-basedlubricating oil, otherwise damage to thesystem will occur.

Repairs should always be performed bya qualified technician, and refrigerantshould be collected in a recoverysystem for recycling.

Brake Fluid

During vehicle operation, the boilingpoint of the brake fluid is continuouslyreduced through the absorption ofmoisture from the atmosphere. Underextremely hard operating conditions,this moisture content can lead to theformation of bubbles in the system thusreducing the system's efficiency.The brake fluid must therefore bereplaced every two years, preferably inthe spring.

It is recommended to use only brakefluid approved by Mercedes Benz.Your authorized Mercedes-Benz dealerwill provide you with additionalinformation.

Premium Unleaded Gasoline Caution!

To maintain the engine's durability andperformance, premium unleadedgasoline must be used. If premiumunleaded is not available and lowoctane fuel is used, follow theseprecautions:

• have the fuel tank filled onlypartially with unleaded regularand fill up with premium unleaded as soon as possible,

• avoid full throttle driving andabrupt acceleration,

• do not exceed an engine speedof 3000 rpm, if the vehicle isloaded with a light load such astwo persons and no luggage,

• do not exceed 2/3 of maximumaccelerator pedal position, if thevehicle is fully loaded or operatingin mountainous terrain.

141

Fuel Requirements

Use only Premium unleaded meetingASTM standard D 439:

The octane number (posted at thepump) must be 91min. It is an averageof both, the Research (R) octane numberand the Motor (M) octane number: [(R+ M)/2]. This is also known as ANTI-KNOCK INDEX.

Unleaded gasoline containingoxygenates such as Ethanol, IPA, IBAand TBA can be used provided theratio of any one of these oxygenates togasoline does not exceed 10%, MTBEnot to exceed 15%.

The ratio of Methanol to gasoline mustnot exceed 3% plus additionalcosolvents.

Using mixtures of Ethanol andMethanol is not allowed. Gasohol,which contains 10% Ethanol and 90%unleaded gasoline, can be used.

These blends must also meet all otherfuel requirements such as resistance tospark knock, boiling range, vaporpressure etc..

Gasoline Additives

A major concern among enginemanufacturers is carbon build upcaused by gasoline. Mercedes-Benzrecommends to use only qualitygasoline containing additives thatprevent the build up of carbon deposits.

After an extended period of using fuelswithout such additives, carbon depositscan build up especially on the intakevalves and in the combustion area,leading to engine performanceproblems such as:

• warm-up hesitation,• unstable idle,• knocking/pinging,• misfire,• power loss.

Damages or malfunctions resultingfrom poor fuel quality are not coveredby the Mercedes-Benz LimitedWarranty.

142

Coolants Therefore the following product isstrongly recommended for use in yourcar: Mercedes-BenzAnticorrosion/Antifreeze Agent.

Before the start of the winter season (oronce a year in the hot southern regions),you should have the anticorrosion/antifreeze concentration checked. Thecoolant is also regularly checked eachtime you bring your vehicle to yourauthorized Mercedes-Benz dealer formaintenance service.

Anticorrosion/antifreeze quantity

Model Approx.freeze-37 ° F(-35 °C)

-45°F(-49°C)

300 SL 5.75 l 6.30 l(6.1 US qt) (6.7 US qt)

500 SL 5.70 l 8.25 l(7.9 US qt) (8.7 US qt)

The engine coolant is a mixture of waterand anticorrosion/anti-freeze, whichprovides:

• corrosion protection• freeze protection• boiling protection (by increasing

the boiling point).

The cooling system was filled at thefactory with a coolant providing freezeprotection to approx. -22 °F (-30 °C) andcorrosion protection.

The coolant solution must be used yearround to provide the necessary corrosionprotection and increase in the boil-overprotection. You should have it replacedevery 3 years.

To provide the important corrosionprotection, the solution must be at least45% anticorrosion/antifreeze (equals afreeze protection to approx. -22 °F[-30 °C]). If you use a solution that ismore than 55% anticorrosion/antifreeze(freeze protection to approx. -49 °F[-45°C]), the engine temperature willincrease due to the lower

heat transfer capability of the solution.Therefore, do not use more than thisamount of anti-corrosion/antifreeze.If the coolant level is low, water andMB anticorrosion/antifreeze should beused to bring it up to the proper level(have cooling system checked for signsof leakage).

The water in the cooling system mustmeet minimum requirements, which areusually satisfied by normal drinkingwater. If you are not sure about thewater quality, consult your authorizedMercedes-Benz dealer.

Anticorrosion/antifreeze

Your vehicle contains a number ofaluminum parts. The use of aluminumcomponents in motor vehicle enginesnecessitates that anticorrosion/antifreeze coolant used in such enginesbe specifically formulated to protect thealuminum parts. (Failure to use suchanticorrosion/antifreeze coolant willresult in a significantly shortenedservice life.)

Consumer Information

This has been prepared as required of allmanufacturers of passenger cars underTitle 49, Code of U.S. FederalRegulations, Part 575 pursuant to the"National Traffic and Motor VehicleSafety Act of 1966".

Uniform Tire Quality Grading

Refer to the tire sidewall for the specifictire grades for the tires with which thisvehicle is equipped.All passenger car tires must conform tofederal safety requirements in addition tothese grades.

Treadwear

The treadwear grade is a comparativerating based on the wear rate of the tirewhen tested under controlled conditionson a specified government test course.For example, a tire graded 150 wouldwear one and one-half (11/2) times aswell on the government course as a tiregraded 100. The relative performance oftires "depends upon the actual conditionsof their use, however

and may depart significantly from thenorm due to variations in driving habits,service practices and differences in roadcharacteristics and climate.

Traction "A", "B", "C"

The traction grades, from highest tolowest, are "A", "B" and "C" and theyrepresent the tire's ability to stop on wetpavement as measured under controlledconditions on specified government testsurfaces of asphalt and concrete. A tiremarked "C" may have poor tractionperformance.

Warning!

The traction grade assigned to thistire is based on braking (straightahead) traction tests and does notinclude cornering (turning) traction.

Temperature "A", "B", "C"The temperature grades are "A" (thehighest). "B" and "C", representing thetire's resistance to the generation of heatand its ability .to dissipate heat when

tested under controlled conditions on aspecified indoor laboratory test wheel.Sustained high temperature can causethe material of the tire to degenerateand reduce tire life, and excessivetemperature can lead to sudden tire fail-ure.
