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 burn. You could be seriously burned.

More information can be found in the "Technical data" section (컄 page 372).

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. 4.8 US qt (4.5 l).

앫 Vehicles with headlamp cleaning sys-

tem: approx. 7.4 US qt (7 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

268

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, independently 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 maximum values or inflate tires below the minimum 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.

269

i Possible differences between the read- ings of a tire pressure gauge of an air hose, e.g. gas station equipment, and the vehicle’s control system can occur. The readings issued by the control sys- tem are more precise.

왘 Switch on ignition. 왘 Press the k button until the current inflation pressures for each tire appear in the multifunction display.

Operation Tires and wheels

Tire pressure changes by approximately 1.5 psi (0.1 bar) per 18°F (10°C) of air temperature change. Keep this in mind when checking tire pressure 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!

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

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.

Checking tire pressure electronically* The tire inflation pressure monitor only functions on wheels that are equipped with the proper electronic sensors. It monitors the tire inflation pressure, as selected by the driver, in all four tires. A warning is is- sued to alert you to a decrease in pressure in one or more of the tires. Tire pressure inquiries are made using the multifunction display (컄 page 121).The present inflation pressures are displayed only after a few minutes’ travel time. You can select the unit of measurement used for the tire inflation pressure by changing the setting in the control system (컄 page 136).

270

Warning!

The tire inflation pressure monitor does not indicate a warning for wrongly selected in- flation pressures. Always adjust tire inflation pressure according to the label affixed on the fuel filler cap.

The tire inflation pressure monitor is not able to issue a warning due to a sudden loss of pressure (e.g. tire puncture caused by a foreign object). In this case bring the vehicle to a halt by carefully applying the brakes and avoiding abrupt steering maneuvers.

Operating radio transmission equip- ment (e.g. wireless headsets, two-way radios) in or near the vehicle could cause the tire inflation pressure moni- tor to malfunction.

Activating the tire inflation pressure monitor You must activate the tire inflation pres- sure monitor in the following cases: 앫 If you have changed the tire pressure 앫 If you have replaced the wheels or tires 앫 If you have installed new wheels or

tires

왘 Be sure that the tire pressure is cor-

rectly set.

왘 Press the ÿ button on the steering wheel repeatedly until the standard dis- play menu appears (컄 page 126).

왘 Press the k button until the infla- tion pressure of each tire appears in the multifunction display.

Operation Tires and wheels

If transporting a deflated road wheel or additional wheel sensors in the vehicle, the tire inflation pressure monitor should not be reactivated until the de- flated wheel or additional wheel sen- sors have been removed from the vehicle. Otherwise, the deflated wheel or additional sensors could confuse the tire inflation pressure monitor system and cause it to malfunction.

왘 Press the reset knob (컄 page 22).

The following message will appear in the multifunction display: Check current tire pressure?.

왘 Press the æ button for Yes.

The following message will appear in the multifunction display: Tire pressure monitor activated Press. display after driving a few mins.

271

Operation Tires and wheels

If you wish to cancel activation: 왘 Press the ç button. If the following message appears in the multifunction display: Tire pressure monitoring Reactivate or Tire pressure monitoring Check tires! 왘 Check the tire inflation pressures and

correct them if necessary.

왘 Restart the activation of the tire infla-

tion pressure monitor.

272

Rotating wheels

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. 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.

If your vehicle is equipped with a tire in- flation pressure monitor*, electronic components are located on the wheel. To prevent damage or incorrect instal- lation, have the tires changed at an au- thorized Mercedes-Benz Center.

Warning!

Have the tightening torque checked after changing a wheel. Wheels could become loose if not tightened with a torque of 96 ft.lb. (130 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 371).

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 the ABS and the ESP in win- ter operation. For safe handling, ensure that all mounted winter tires are of the same make and have the same tread design.

Warning!

Winter tires having a tread depth under 0.16 in (4 mm) must be replaced. They are no longer 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 to this.

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

273

Operation Winter driving

Block heater (Canada only)

Snow chains

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

When driving with snow chains, always se- lect the raised level of the level control sys- tem AIRMATIC DC* (컄 page 209). Other settings may result in damage to your vehi- cle. 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 76) 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 Only use snow chains that are ap-

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

Use of snow chains is not permissible with tire size 245/45 R17 (컄 page 361).

Operation Vehicle care 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.

In operation, your vehicle is subjected to varying external influences which, if gone unchecked, can attack the paintwork as well as the undercarriage and cause last- ing 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

280

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, for ex- ample: 앫 Near the ocean 앫 In industrial areas (smoke, exhaust

emissions)

앫 During winter operation

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 the start of corrosion. In doing so, do not neglect the underside of the vehicle. A prerequisite for a thorough check is a washing of the undercarriage followed by a thorough inspection. Dam- aged areas need to be reundercoated. 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.

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 entitled "Vehicle Care Guide".

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

Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEY- LESS-GO* is in close proximity, i.e. within approx. 3 ft. (approx. 1 m), the vehicle could be inadvertently locked or unlocked.

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.

Operation Vehicle care

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 in 3 to 5 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.).

281

Operation Vehicle care

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 ap- proved 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.

282

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

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.

Rinse with clear water and thoroughly wipe 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 undercarriage, do not forget to clean the inner sides of the wheels. Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEY- LESS-GO* is in close proximity, i.e. within approx. 3 ft. (approx. 1 m), the vehicle could be inadvertently locked or unlocked.

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

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.

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. Other- wise the wiper motor can suddenly turn on and cause injury.

Fold the windshield wiper arms away from the windshield in a vertical posi- tion only. They could otherwise dam- age the hood (컄 page 337). Fold the windshield wiper arms back onto the windshield before turning the key in the starter switch.

284

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, us- ing a soft bristle brush and a strong spray of water. Follow the instructions on the container.

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

Cleaning the Parktronic* system sensors

1 Parktronic* sensors Use a mild car wash detergent, such as Mercedes-Benz approved Car Shampoo with plenty of water. When using a steam cleaner or power washer, aim nozzle only briefly from a min- imum distance of 4 in. (10 cm) at sensors 1. To prevent scratches, never apply strong force and use only a soft, non-scratchy cloth when cleaning the sensor. Do not at- tempt to wipe dirty sensors with a dry cloth or sponge.

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

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 a soft bristle brush, or use a dry-shampoo cleaner in case of excessive dirt.

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.

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.

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.

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

Operation Vehicle care

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.
