Operation The first 1000 miles (1500 km)

In the “Operation” section you will find de- tailed information on operating, maintain- ing and caring for your vehicle.

222

The first 1000 miles (1500 km) The more cautiously you treat your vehicle during the break-in period, the more satis- fied you will be with its performance later on. 앫 Drive your vehicle during the first

1000 miles (1500 km) at varying but moderate vehicle and engine speeds. 앫 During this period, avoid heavy loads

(full throttle driving) and excessive engine speeds (no more than 2/3 of maximum rpm in each gear).

앫 Shift gears in a timely manner. 앫 Avoid accelerating by kick-down. 앫 Do not attempt to slow the vehicle

down by shifting to a lower gear using the selector lever.

앫 Select positions 3, 2 or 1 only when driving at moderate speeds (for hill driving).

After 1000 miles (1500 km) you may gradually increase vehicle and engine speeds to the permissible maximum.

Additional instructions for AMG vehicles: 앫 During the first 1000 miles

(1500 km), do not exceed a speed of 85 mph (140 km/h).

앫 During this period, avoid engine speeds above 4500 rpm in each gear.

All of the above instructions, as may apply to your vehicle type, also apply when driving the first 1000 miles (1500 km) after the engine or the rear differential has been replaced

Always obey applicable speed limits.

Operation Driving instructions

Drinking and driving

Pedals

Warning!

Warning!

Keep driver’s foot area clear at all times. Ob- jects stored in this area may impair pedal movement.

Drinking and driving and/or taking drugs and driving are very dangerous combina- tions. Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judgement.

The possibility of a serious or even fatal ac- cident is sharply increased when you drink or take drugs and drive.

Please don’t drink or take drugs and drive or allow anyone to drive after drinking or taking drugs.

Driving instructions Drive sensibly – save fuel

Fuel consumption, to a great extent, de- pends on driving habits and operating con- ditions. To save fuel you should: 앫 Keep tires at the recommended infla-

tion pressures.

앫 Remove unnecessary loads. 앫 Remove roof rack when not in use. 앫 Allow engine to warm up under low

load use.

앫 Avoid frequent acceleration and decel-

eration.

앫 Have all maintenance work performed

at regular intervals by an authorized Mercedes-Benz Center.

Fuel consumption is also increased by driv- ing in cold weather, in stop-and-go traffic, on short trips and in hilly country.

223

Operation Driving instructions

Power assistance

Warning!

When the engine is not running, the brake and steering systems are without power as- sistance. Under these circumstances, a much greater effort is necessary to stop or steer the vehicle

Brakes

Warning!

After driving in heavy rain for some time without applying the brakes or through wa- ter deep enough to wet brake components, the first braking action may be somewhat reduced and increased pedal pressure may be necessary to obtain expected braking ef- fect. Maintain a safe distance from vehicles in front.

224

Resting your foot on the brake pedal will cause excessive and premature wear of the brake pads.

It can also result in the brakes overheating, thereby significantly reducing their effec- tiveness. It may not be possible to stop the vehicle in sufficient time to avoid an acci- dent.

To help prevent brake disk corrosion after driving on wet road surfaces (particularly salted roads), it is advisable to brake the vehicle with considerable force prior to parking. The heat generated serves to dry the brakes. If your brake system is normally only subject to moderate loads, you should occasionally test the effectiveness of the brakes by applying above-normal braking pressure at higher speeds. This will also enhance the grip of the brake pads.

Be very careful not to endanger other road users when you apply the brakes. Refer to the description of the Brake Assist System (BAS) (컄 page 74).

If the parking brake is released and the brake warning lamp in the instrument clus- ter stays on, the brake fluid level in the res- ervoir is too low. Brake pad wear or a leak in the system may be the reason for low brake fluid in the res- ervoir. Have the brake system inspected at an au- thorized Mercedes-Benz Center immedi- ately. All checks and service work on the brake system should be carried out by an autho- rized Mercedes-Benz Center. Only install brake pads and brake fluid recommended by Mercedes-Benz.

Warning!

Driving off

Parking

Operation Driving instructions

Set the parking brake whenever park- ing or leaving the vehicle. In addition, move selector lever to position P (man- ual transmission: first or reverse gear). In addition, when parking on hills, always turn front wheels towards road curb.

If other than recommended brake pads are installed, or other than recommended brake fluid is used, the braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired. This can result in an accident.

When driving down long and steep grades, relieve the load on the brakes by shifting into a lower gear to use the engine’s braking power. This helps pre- vent overheating of the brakes and re- duces brake pad wear.

After hard braking, it is advisable to drive on for some time, rather than immediately parking, so that the air stream will cool down the brakes faster.

Apply the brakes to test them briefly after driving off. Perform this procedure only when the road is clear of other traffic. Warm up the engine smoothly. Do not place full load on the engine until the oper- ating temperature has been reached. When starting off on a slippery surface, do not allow one drive wheel to spin for an ex- tended period with the ESP switched off. Doing so may cause serious damage to the drive train which is not covered by the Mercedes-Benz Limited Warranty.

Simultaneously depressing the accelerator pedal and applying the brake reduces engine performance and causes premature brake and drivetrain wear.

225

Operation Driving instructions

Warning!

Tires

Do not park this vehicle in areas where com- bustible materials such as grass, hay or leaves can come into contact with the hot exhaust system, as these materials could be ignited and cause a vehicle fire.

To reduce the risk of personal injury as a re- sult of vehicle movement, before turning off the engine and leaving the vehicle always: 앫 Keep right foot on brake pedal. 앫 Firmly depress parking brake pedal. 앫 Move the selector lever to position P (manual transmission: first or reverse gear).

앫 Slowly release brake pedal. 앫 When parked on an incline, turn front

wheels towards the road curb. 앫 Turn the key to starter switch

position 0.

앫 Take the key and lock vehicle when leav-

ing.

226

Warning!

The tread wear indicator appears as a solid band across the tread.

Warning!

Do not allow your tires to wear down too far. As tread depth approaches 1/16 in (1.5 mm), the adhesion properties on a wet road are sharply reduced.

Depending upon the weather and/or road surface (conditions), the tire traction varies widely.

Specified tire pressures must be main- tained. This applies particularly if the tires are subject to high loads (e.g. high speeds, heavy loads, high ambient temperatures).

If you feel a sudden significant vibration or ride disturbance, or you suspect that possi- ble damage to your vehicle has occurred, you should turn on the hazard warning flash- ers, carefully slow down, and drive with cau- tion to an area which is a safe distance from the road.

Inspect the tires and the vehicle underbody for possible damage. If the vehicle or tires appear unsafe, have it towed to the nearest Mercedes-Benz Center or tire dealer for re- pairs.

Tread wear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and be- come visible at a tread depth of approxi- mately 1/16 in (1.5 mm), at which point the tire is considered worn and should be replaced.

Warning!

Tire traction

Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat build-up and possibly a fire.

The safe speed on a wet, snow covered or icy road is always lower than on a dry road. You should pay particular attention to the condition of the road whenever the outside temperatures are close to the freezing point.

Hydroplaning

Warning!

Depending on the depth of the water layer on the road, hydroplaning may occur, even at low speeds and with new tires. Reduce vehicle speed, avoid track grooves in the road and apply brakes cautiously in the rain.

If ice has formed on the road, tire traction will be substantially reduced. Under such weather conditions, drive, steer and brake with extreme caution.

Mercedes-Benz recommends M+S rated radial-ply tires for the winter season for all four wheels to insure normal balanced handling characteristics. On packed snow, they can reduce your stopping distance compared to summer tires. Stopping dis- tance, however, is still considerably great- er than when the road is not covered with snow or ice. Exercise appropriate caution.

Operation Driving instructions

Tire speed rating

Additional information on winter tires can be found under “Winter tires” (컄 page 245).

Warning!

Even when permitted by law, never operate a vehicle at speeds greater than the maxi- mum speed rating of the tires.

Exceeding the maximum speed for which tires are rated can lead to sudden tire fail- ure, causing loss of vehicle control and pos- sibly resulting in an accident and/or personal injury and possible death, for you and for others.

227

Operation Driving instructions

C 240, C 240 4MATIC, C 320, and C 320 4MATIC Your vehicle is factory equipped with “H”-rated tires, which have a speed rating of 130 mph (210 km/h). An electronic speed limiter prevents your vehicle from exceeding a speed of 130 mph (210 km/h).

C 230 Kompressor Sport, C 320 Sport, and C 320 4MATIC Sport Your vehicle is factory equipped with “W”-rated tires, which have a speed rating of 168 mph (270 km/h). An electronic speed limiter prevents your vehicle from exceeding a speed of 130 mph (210 km/h).

228

C 32 AMG Your vehicle is factory equipped with “Y”-rated tires, which have a speed rating of 188 mph (300 km/h). An electronic speed limiter prevents your vehicle from exceeding a speed of 155 mph (250 km/h). Regardless of the tire speed rating, local speed limits should be obeyed. Use pru- dent driving speeds appropriate to prevail- ing conditions.

Winter driving instructions

The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering maneuvers. Do not use the cruise control system under such conditions. When the vehicle is in danger of skidding, move selector lever to position N or in case of manual transmission declutch. Try to keep the vehicle under control by cor- rective steering action.

Information on driving with snow chains, see “Snow chains” (컄 page 246).

Warning!

On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehi- cle control. Your vehicle’s ABS will not pre- vent this type of control loss.

Road salts and chemicals can adversely af- fect braking efficiency. Increased pedal force may become necessary to produce the normal braking effect. We therefore recommend depressing the brake pedal periodically when traveling at length on salt-strewn roads. This can bring road salt impaired braking efficiency back to normal. Be very careful that you carry out these braking maneu- vers without endangering any other road users. If the vehicle is parked after being driven on salt treated roads, the braking efficien- cy should be tested as soon as possible af- ter driving is resumed while observing the safety rules in the previous paragraph.

Operation Driving instructions

Warning!

Standing water

If the vehicle becomes stuck in snow, make sure that snow is kept clear of the exhaust pipe and from around the vehicle with the engine running. Otherwise, deadly carbon monoxide (CO) gases may enter vehicle in- terior resulting in unconsciousness and death.

To assure sufficient fresh air ventilation, open a window slightly on the side of the ve- hicle not facing the wind

Warning!

The outside temperature indicator is not de- signed to serve as an ice-warning device and is therefore unsuitable for that purpose. In- dicated temperatures just above the freez- ing point do not guarantee that the road surface is free of ice.

For more information, see “Winter driving” (컄 page 245).

Do not drive through flooded areas or water of unknown depth. If you must drive through standing wa- ter, drive slowly to prevent water from entering the passenger compartment or the engine compartment. Water in these areas could cause damage to electrical components or wiring of the engine or transmission, or could result in water being ingested by the engine through the air intake causing severe internal engine damage. Any such damage is not covered by the Mercedes-Benz Limited Warranty.

229

Operation Driving instructions

Passenger compartment

Warning!

Always fasten items being carried as securely as possible.

In an accident, during hard braking or sud- den maneuvers, loose items will be thrown around inside the vehicle, and cause injury to vehicle occupants unless the items are securely fastened in the vehicle.

The trunk is the preferred place to carry ob- jects.

Driving abroad

Abroad, there is a widely-spread Mercedes-Benz service network at your disposal. If you plan to drive into areas which are not listed in the index of your Mercedes-Benz Center directory, you should request pertinent information from your authorized Mercedes-Benz Center.

Warning!

Warning!

Please do not forget that your primary re- sponsibility is to drive the vehicle safely. Only operate the COMAND (Cockpit Man- agement and Data System), radio or tele- phone1 if road, weather and traffic conditions permit.

Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your vehicle is covering a distance of approximately 44 feet (approximately 13.5 m) every sec- ond.

1 Observe all legal requirements

Never operate radio transmitters equipped with a built-in or attached antenna (i.e. with- out being connected to an external antenna) from inside the vehicle while the engine is running. Doing so could lead to a malfunc- tion of the vehicle’s electronic system, possibly resulting in an accident and personal injury.

Radio transmitters, such as a portable tele- phone or a citizens band unit should only be used inside the vehicle if they are con- nected to an antenna that is installed on the outside of the vehicle. Refer to the radio transmitter operation in- structions regarding use of an external an- tenna.

Catalytic converter

Your Mercedes-Benz is equipped with monolithic type catalytic converters, an important element in conjunction with the oxygen sensors to achieve substantial con- trol of the pollutants in the exhaust emis- sions. Keep your vehicle in proper operating condition by following our rec- ommended maintenance instructions as outlined in your Service Booklet.

To prevent damage to the catalytic con- verters, use only premium unleaded gasoline in this vehicle. Any noticeable irregularities in engine operation should be repaired promptly. Otherwise, excessive unburned fuel may reach the catalytic converter, causing it to overheat and start a fire.

Operation Driving instructions

Warning!

Emission control

As with any vehicle, do not idle, park or op- erate this vehicle in areas where combusti- ble materials such as grass, hay or leaves can come into contact with the hot exhaust system, as these materials could be ignited and cause a vehicle fire.

Certain systems of the engine serve to keep the toxic components of the exhaust gases within permissible limits required by law. These systems, of course, will function properly only when maintained strictly ac- cording to factory specifications. Any ad- justments on the engine should, therefore, be carried out only by qualified Mercedes-Benz Center authorized techni- cians. Engine adjustments should not be altered in any way. Moreover, the specified service jobs must be carried out regularly according to Mercedes-Benz servicing re- quirements. For details refer to the Service Booklet.

231

Operation Driving instructions

Warning!

Coolant temperature

Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide, and inhaling it can cause uncon- sciousness and lead to death.

Do not run the engine in confined areas (such as a garage) which are not properly ventilated. If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and corrected immediately. If you must drive under these conditions, drive only with at least one win- dow fully open at all times.

During severe operating conditions and stop-and-go city traffic, the coolant tem- perature may rise close to approx. 248°F (120°C). The engine should not be operated with the coolant temperature over 248°F (120°C). Doing so may cause serious en- gine damage which is not covered by the Mercedes-Benz Limited Warranty.

Warning!

앫 Driving when your engine is badly over-

heated can cause some fluids, which may have leaked into the engine com- partment, to catch fire. You could be se- riously burned.

앫 Steam from an overheated engine can cause serious burns and can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it.

Turn off the engine, get out of the vehicle and do not stand near the vehicle until it cools down.

Operation Engine compartment

Battery

Your vehicle’s battery is located in the en- gine compartment (컄 page 303). The battery should always be sufficiently charged in order to achieve its rated ser- vice life. If you use your vehicle mostly for short dis- tance trips, you will need to have the bat- tery charge checked more frequently. When replacing the battery, always use batteries approved by Mercedes-Benz. If you do not intend to operate your vehicle for an extended period of time, consult an authorized Mercedes-Benz Center about steps you need to observe.

240

Always use washer solvent/antifreeze where temperatures may fall below freezing. Failure to do so could result in damage to the washer system/reser- voir.

Warning!

Washer solvent/antifreeze is highly flam- mable. Do not spill washer solvent/ antifreeze on hot engine parts, because it may ignite. You could be seriously burned.

More information can be found in the “Technical data” section (컄 page 338).

Windshield washer system and headlamp cleaning* system

Fluid for the windshield washer system and the headlamp cleaning system is supplied from the windshield washer reservoir. It has a capacity of 앫 Vehicles without headlamp cleaning

system: approx. 3.2 US qt. (3.0 l). 앫 Vehicles with headlamp cleaning

system*: approx. 6.4 US qt. (6.0 l). During all seasons, add MB Windshield Washer Concentrate “S” to water. Premix the windshield washer fluid in a suitable container. 왘 Refill the reservoir with MB Windshield

Washer Concentrate and water (or commercially available premixed wind- shield washer solvent/antifreeze, de- pending on ambient temperatures).

Operation Tires and wheels Tires and wheels See your authorized Mercedes-Benz Cen- ter for information on tested and recom- mended rims and tires for summer and winter operation. They can also offer ad- vice concerning tire service and purchase.

Warning!

Replace rims or tires with the same designa- tion, manufacturer and type as shown on the original part. See your authorized Mercedes-Benz Center for further informa- tion. If incorrectly sized rims and tires are mounted: 앫 The wheel brakes or suspension compo-

nents can be damaged

앫 The correct operating clearance of the wheels and the tires are no longer guar- anteed

242

Warning!

Important guidelines

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

When replacing rims, use only genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can re- sult in the bolts loosening and possibly an accident.

Retread tires are not tested or recom- mended by Mercedes-Benz, since previous damage cannot always be recognized on retreads. Mercedes-Benz can therefore not assure the operating safety of the vehi- cle when such tires are used. See your authorized Mercedes-Benz Cen- ter for information on tested and recom- mended rims and tires for summer and winter operation.

앫 Use only sets of tires and rims of the

same type and make.

앫 Tires must be of the correct size for the

rim.

앫 Break in new tires for approximately

60 miles (100 km) at moderate speeds.

앫 Regularly check the tires and rims for

damage.

앫 If vehicle is heavily loaded, check tire

pressure and correct as required.

앫 Do not allow your tires to wear down too far. Adhesion properties on wet roads are sharply reduced at tread depths under 1/8 in (3 mm).

앫 When replacing individual tires, you should mount new tires on the front wheels first (on vehicles with same-sized wheels all around).

Operation Tires and wheels

Life of tire

Direction of rotation

The service life of a tire is dependent upon varying factors including but not limited to: 앫 Driving style 앫 Tire pressure 앫 Distance driven

Warning!

Unidirectional tires offer added advantag- es, such as better aquaplaning perfor- mance. To benefit, however, you must ensure that the tires rotate in the direction specified. An arrow on the sidewall indicates the in- tended direction of tire rotation.

Checking tire inflation pressure

Tires and spare tire should be replaced after six years, regardless of the remaining tread.

Warning!

Keep unmounted tires in a cool, dry place with as little exposure to light as possible. Protect tires from contact with oil, grease and gasoline.

If the tire pressure repeatedly drops 앫 check the tires for punctures from for-

eign objects

앫 check to see whether air is leaking from

the valves or from around the rim

If the tires are warm you should only cor- rect the tire pressure if it is too low for cur- rent operating conditions. A table on the fuel filler flap lists the spec- ified tire inflation pressures for warm and cold tires as well as for various operating conditions.

The pressures listed for light loads are minimum values offering high driving comfort. Increased inflation pressures listed for heavier loads may also be used for light loads. These higher pressures produce favorable handling characteristics. The ride of the vehicle, however, will be somewhat harder. Never exceed the max. values or inflate tires below the min. values listed in the fuel filler flap.

Regularly check your tire pressure at inter- vals of no more than 14 days. Correct the tire pressure only when tires are cold.

Tire pressure changes by approx. 1.5 psi (0.1 bar) per 18°F (10°C) of air tempera- ture change.

243

Operation Tires and wheels

Keep this in mind when checking tire pres- sure where the temperature is different from the outside temperature. Tire temperature and tire pressure are also increased while driving, depending on the driving speed and the tire load. Check the spare tire periodically for condi- tion and inflation. Spare tires will age and become worn over time even if never used, and thus should be inspected and replaced when necessary.

Warning!

Follow recommended inflation pressures.

Do not overinflate tires. Overinflated tires can result in sudden deflation (blowout) be- cause they are more likely to become punc- tured or damaged by road debris, potholes, etc.

Do not underinflate tires. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated.

244

Do not overload the tires by exceeding the specified vehicle capacity weight (as indicat- ed by the label on the pillar in the driver’s door opening). Overloading the tires can overheat them, possibly causing a blowout.

Rotating wheels

Warning!

Rotate the wheels before the characteris- tic tire wear pattern becomes visible (shoulder wear on front wheels and tread center wear on rear wheels). Thoroughly clean the inner side of the wheels after each rotation. Check and en- sure proper tire inflation pressure.

Warning!

Rotate front and rear wheels only if they are of the same size.

On vehicles with the same wheel size all around, wheels can be rotated every 3000 to 6000 miles (5000 to 10000 km), or sooner if necessary, according to the de- gree of tire wear. The same direction of tire rotation must be retained.

Have the tightening torque checked after changing a wheel. Wheels could become loose if not tightened with a torque of 80 ft.lb. (110 Nm).

Use only genuine Mercedes-Benz wheel bolts specified for your vehicle's rims.

Winter driving Before the onset of winter have your vehi- cle winterized at an authorized Mercedes-Benz Center. This service in- cludes: 앫 Check of anticorrosion and antifreeze

concentration.

앫 Addition of cleaning concentrate to the water of the windshield and headlamp cleaning system. Add MB Concentrate “S” to a premixed windshield washer solvent/antifreeze which is formulated for below freezing temperatures (컄 page 338).

앫 Battery test. Battery capacity drops

with decreasing ambient temperature. A well charged battery helps to ensure that the engine can be started, even at low ambient temperatures.

앫 Tire change. We recommend M+S rat- ed radial-ply tires on all four wheels for the winter season.

Winter tires

Always use winter tires at temperatures below 39°F (4°C) and whenever wintry road conditions prevail. Use of winter tires is the only way to achieve the maximum ef- fectiveness of ABS, ESP and 4MATIC* in winter operation. For safe handling, ensure that all mounted winter tires are of the same make and have the same tread design.

Warning!

Winter tires with a tread depth under 0.16 in (4 mm) must be replaced. They are no long- er suitable for winter operation.

Operation Winter driving

Always observe the speed rating of the winter tires installed on your vehicle. If the maximum speed for which your tires are rated is below the speed rating of your ve- hicle, you must place a notice to this effect where it will be seen by the driver. Such no- tices are available from your tire dealer or from any authorized Mercedes-Benz Cen- ter.

Warning!

If you use your spare tire when winter tires are fitted on the other wheels, be aware that the difference in tire characteristics may very well impair turning stability and that overall driving stability may be reduced. Adapt your driving style accordingly.

Have the spare tire replaced with a winter tire at the nearest authorized Mercedes-Benz Center.

Operation Winter driving

Block heater (Canada only)

Snow chains

The engine is equipped with a block heater. The electrical cable may be installed at your authorized Mercedes-Benz Center.

Snow chains should only be driven on snow-covered roads at speeds not to ex- ceed 30 mph (50 km/h). Remove chains as soon as possible when driving on roads without snow.

When driving with snow chains, you may wish to deactivate the ESP (컄 page 75) before setting the vehicle in motion. This will improve the vehi- cle‘s traction.

Please observe the following guidelines when using snow chains: 앫 Use of snow chains is not permissible

with all wheel/tire combinations.

앫 Chains should only be used on the rear

wheels. Follow the manufacturer's mounting instructions.

앫 Use only snow chains that are ap-

proved by Mercedes-Benz. Your autho- rized Mercedes-Benz Center will be glad to advise you on this subject.

Even on vehicles with all-wheel-drive use snow chains on rear tires only. Use of snow chains is not permissible with tire sizes: 앫 225/45 R17 91 H M+S 앫 225/45 R17 91 W 앫 245/40 R17 91 Y 앫 T 125/90 R16 M 98

Maintenance We strongly recommend that you have your vehicle serviced by your authorized Mercedes-Benz Center, in accordance with the Service Booklet at the times called for by the FSS (Flexible Service System). Failure to have the vehicle maintained in accordance with the Service Booklet at the designated times/mileage called for by the FSS may result in vehicle damage not covered by the Mercedes-Benz Limited Warranty. FSS will notify you when your next service is due. Approximately one month before your next service is due, one of the following mes- sages will appear in the multifunction dis- play while you are driving or when you switch on the ignition (example service A):

SERVICE A IN XX DAYS SERVICE A IN XX MILES (KM) SERVICE A DUE NOW!

The type of service due is indicated in the speedometer display field: 9 Minor service (A) ½ Major service (B)

The interval between services depends on your driving habits. A gentle driving style, moderate engine speeds and the avoidance of short distance trips will lengthen the interval between services.

Operation Maintenance

Clearing the service indicator

The service indicator is automatically cleared 앫 after ten seconds when you switch on the ignition or when reaching the ser- vice threshold while driving

앫 after 30 seconds, once the suggested

service term has passed

You can also clear it yourself. 왘 Press the reset knob on the instrument

cluster (컄 page 22).

Service term exceeded

If you have exceeded the suggested ser- vice term, you will see the following mes- sage in the multifunction display:

Vehicle care Cleaning and care of vehicle

Warning!

Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the partic- ular container. Always open your vehicle’s doors or windows when cleaning the inside.

Never use fluids or solvents that are not de- signed for cleaning your vehicle.

While in operation, even while parked, your vehicle is subject to varying external influ- ences which, if gone unchecked, can at- tack the paintwork as well as the underbody and cause lasting damage. Such damage is caused not only by ex- treme and varying climatic conditions, but also by: 앫 Air pollution 앫 Road salt 앫 Tar, gravel and stone chipping

To avoid paint damage, you should imme- diately remove: 앫 Grease and oil 앫 Fuel 앫 Coolant 앫 Brake fluid 앫 Insects 앫 Tree resins etc. Frequent washing reduces and/or elimi- nates the aggressiveness and potency of the above adverse influences. More frequent washings are necessary to deal with unfavorable conditions: 앫 Near the ocean 앫 In industrial areas (smoke, exhaust

emissions)

앫 During winter operation

Operation Vehicle care

You should check your vehicle from time to time for stone chipping or other damage. Any damage should be repaired as soon as possible to prevent corrosion. In doing so, do not neglect the underbody of the vehicle. A prerequisite for a thor- ough check is a washing of the underbody followed by a thorough inspection. Dam- aged areas need to be re-undercoated. Your vehicle has been treated at the facto- ry with a wax-base rustproofing in the body cavities which will last for the lifetime of the vehicle. Post-production treatment is neither necessary nor recommended by Mercedes-Benz because of the possibility of incompatibility between materials used in the production process and others ap- plied later. We have selected car-care products and compiled recommendations which are specially matched to our vehicles and which always reflect the latest technology. You can obtain Mercedes-Benz approved car-care products at your authorized Mercedes-Benz Center.

249

Operation Vehicle care

Scratches, corrosive deposits, corrosion or damage due to negligent or incorrect care cannot always be removed or repaired with the car-care products recommended here. In such cases it is best to seek aid at your authorized Mercedes-Benz Center. The following topics deal with the cleaning and care of your vehicle and give important “how-to” information as well as references to Mercedes-Benz approved car-care prod- ucts. Additional information can be found in the booklet “Vehicle Care Guide”.

Power washer When using a power washer for cleaning the vehicle always observe manufacturer’s operating instructions.

250

Never use a round nozzle to power wash tires. The intense jet of water can result in damage to the tire. Always replace a damaged tire. Always keep the jet of water moving across the surface. Do not aim directly at electrical parts, electrical connec- tors, seals, or other rubber parts.

Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended.

Paintwork, painted body components Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not “bead up”, normally every three to five months, depending on climate and washing detergent used.

Mercedes-Benz approved Paint Cleaner should be applied if the paint surface shows signs of embedded dirt (i.e. loss of gloss). Do not apply any of these products or wax if your vehicle is parked in the sun or if the hood is still hot. Use the appropriate MB-Touch-Up Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehi- cle doors etc.).

Engine cleaning Prior to cleaning the engine compartment make sure to protect electrical compo- nents and connectors from contact with water and cleaning agents. Corrosion protection, such as MB Anticor- rosion Wax should be applied to the engine compartment after every engine cleaning. Before applying, all control linkage bush- ings and joints should be lubricated. The poly-V-belt and all pulleys should be pro- tected from any wax.

Vehicle washing Do not use hot water or wash your vehicle in direct sunlight. Use only a mild car wash detergent, such as Mercedes-Benz approved Car Shampoo. Thoroughly spray the vehicle with a dif- fused jet of water. Direct only a very weak spray towards the ventilation intake. Use plenty of water and rinse the sponge and chamois frequently. Rinse with clear water and thoroughly dry with a chamois. Do not allow cleaning agents to dry on the finish. Due to the width of the vehicle, fold in out- side mirrors prior to running the vehicle through an automatic car wash to prevent damage to the mirrors. In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the underbody, do not for- get to clean the inner sides of the wheels.

Ornamental moldings For regular cleaning and care of very dirty chrome-plated parts, use a chrome cleaner.

Headlamps, tail lamps, turn signal lenses Use a mild car wash detergent, such as Mercedes-Benz approved Car Shampoo, with plenty of water. To prevent scratches, never apply strong force and use only a soft, non-scratchy cloth when cleaning the lenses. Do not at- tempt to wipe dirty lenses with a dry cloth or sponge.

Wiper blades Clean the wiper blade inserts with a clean cloth and detergent solution.

Operation Vehicle care

For safety reasons, switch off wipers and remove key from starter switch be- fore cleaning the wiper blades, other- wise the wiper motor can suddenly turn on and cause injury.

Fold the windshield wiper arms back onto the windshield before turning the key in the starter switch.

Window cleaning Use a window cleaning solution on all glass surfaces. An automotive glass cleaner is recommended.

For safety reasons, switch off wipers and remove key from starter switch be- fore cleaning the windshield, otherwise the wiper motor can suddenly turn on and cause injury.

251

Operation Vehicle care

Light alloy wheels Mercedes-Benz approved Wheel Care should be used for regular cleaning of the light alloy wheels. If possible, clean wheels once a week with Mercedes-Benz approved Wheel Care, using a soft bristle brush and a strong spray of water. Follow instructions on container.

Use only acid-free cleaning materials. Acid could lead to corrosion.

Instrument cluster Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution. Wipe with a cloth moist- ened in lukewarm solution. Do not use scouring agents.

252

Steering wheel and gear selector lever Wipe with a damp cloth and dry thoroughly or clean with Mercedes-Benz approved Leather Care.

Headliner and shelf below rear window Clean with soft bristle brush, or use a dry-shampoo cleaner in case of excessive dirt.

Cup holder Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution. Wipe with a cloth moist- ened in lukewarm solution. Do not use scouring agents.

Seat belts The webbing must not be treated with chemical cleaning agents. Use only clear, lukewarm water and soap. Do not dry the webbing at temperatures above 176°F (80°C) or in direct sunlight.

Hard plastic trim items Pour Mercedes-Benz approved Interior Care onto soft lint-free cloth and apply with light pressure.

Plastic and rubber parts Do not use oil or wax on these parts.

Warning!

Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection.

MB Tex upholstery Pour Mercedes-Benz approved Interior Care onto soft lint-free cloth and apply with light pressure.

Leather upholstery Using aftermarket seat covers or wearing clothing that have the tendency to give off coloring (e.g. when wet etc.) may cause the upholstery to become permanently dis- colored. By lining the seats with a proper intermediate cover, contact-discoloration will be prevented. Wipe leather upholstery with a damp cloth and dry thoroughly or clean with Mercedes-Benz approved Leather Care. Exercise particular care when cleaning per- forated leather as its underside should not become wet.
