Operation Tires and wheels

Warning!

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 flap.

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.

Follow recommended inflation pressures.

Do not overinflate tires. Overinflated tires can result in a sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, pot- holes etc.

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

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.

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.

This display appears until the individual inflation pressure values are matched with the tires. The individual values are then displayed.

If you wish to cancel activation: 왘 Press the ç button. If the following message appears in the multifunction display field: REACTIVATE TIRE PRES. MONITOR or TIRE PRES. CHECK TIRES! 왘 Check the tire inflation pressures and

correct them if necessary.

왘 Reactivate the tire inflation pressure

monitor.

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. It is necessary to activate the tire inflation pressure monitor*.

Operation Tires and wheels

If your vehicle is equipped with a tire in- flation pressure monitor*, there are electronic components built into the wheel. Do not use mounting tools in the area of the valve as they could damage the electronic components. 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 110 ft.lb. (150 Nm).

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

251

Operation Winter driving 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 pre-mixed windshield washer solvent/antifreeze which is formulated for temperatures below freezing point (컄 page 343)

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.

252

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

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 Center.

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.

Block heater*

Snow chains

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

When using snow chains, the vehicle should only be driven at vehicle height 1 (컄 page 191). 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.

Operation Winter driving

Please observe the following guidelines when using snow chains: 앫 Using 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.

Do not use snow chains with tire sizes 245/45 R18 on 8½J x 18 rim and 265/40 R18 in general (컄 page 331). Do not use snow chains on tires mount- ed on AMG rims.

253

Operation Maintenance 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 XXXXX MILES (KM) SERVICE A IN XXX DAYS SERVICE A IN X DAY SERVICE A DUE NOW!

254

The type of service due is indicated in the multifunction display: 9 Minor service (A) ´ 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.

Clearing the service indicator

The service indicator is automatically cleared after 30 seconds. You can also clear it yourself. 왘 Press the reset button J (컄 page 22)

in the instrument cluster.

Service term exceeded

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

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.

While in operation, even while parked, your vehicle is subjected to varying external in- fluences 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

256

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 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. Scratches, corrosive deposits, corrosion or damage due to negligent or incorrect care cannot always be removed or repaired with

! 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.

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 the manufac- turer’s operating instructions.

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

Operation Vehicle care

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 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.).

Engine cleaning Prior to cleaning the engine compartment make sure to protect electrical compo- nents and connectors from contact with water and cleaning agents.

257

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.

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

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.

Operation Vehicle care

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. Rinse with clear water and thoroughly dry with a chamois. Do not allow cleaning agents to dry on the finish.

Headliner Clean with 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.

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.
