왔 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 temperatures below freezing point (컄 page 406).
앫 Battery test. Battery capacity drops
with decreasing ambient temperature. A well charged battery helps to ensure that the engine can be started and the SBC brake system will be fully opera- tional, even at low ambient tempera- tures.
앫 Tire change. Mercedes-Benz recom-
mends M+S rated radial-ply tires with a minimum tread depth of approximately 1/6 in (4 mm) on all four wheels for the winter season.
Winter tires
Always use winter tires at temperatures below 45°F (7°C) and whenever wintry road conditions prevail. Use of winter tires is the only way to achieve the maximum ef- fectiveness of the 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 of less than 1/6 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 at your tire dealer or 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.

Operation Vehicle care 왔 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 undercarriage and cause lasting damage.
302
Such damage is caused not only by ex- treme and varying climatic conditions, but also by: 앫 Air pollution 앫 Road salt 앫 Tar 앫 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 Bird droppings 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.
Operation Vehicle care
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 “Vehicle Care Guide”.
Power washer When using a power washer for cleaning the vehicle, always observe the manufac- turer’s operating instructions.
Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended.
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 approximately 3 ft (approxi- mately 1 m), the vehicle could be inad- vertently 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.
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.).
303
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.
304
Ornamental moldings For regular cleaning and care of very dirty chrome-plated parts, use a chrome clean- er.
Headlamps, tail lamps, side markers, 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 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 approximately 3 ft (approxi- mately 1 m), the vehicle could be inad- vertently locked or unlocked.

Display messages Brake fluid Visit workshop!
Possible cause There is insufficient brake fluid in the reservoir.
Warning!
Driving while these messages are displayed can result in an accident. Have your brake system checked immediately.
If there is a malfunction in the SBC brake system, we recommend that the vehicle be transported with all wheels off the ground using flatbed or appropriate wheel lift/dolly equipment.
A tow bar must be used if circumstances do not permit the use of the recommended towing methods and the vehicle requires towing with all four wheels on the ground.
Towing the vehicle with all four wheels on the ground is only permissible for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h). For more infor- mation, refer to “Towing the vehicle” (컄 page 381). If the SBC brake system enters its emergen- cy operation mode, the driver must apply significantly greater brake pedal pressure and depress the pedal much further than normal to obtain braking effect. If neces- sary, apply full pressure to the brake pedal. Brakes may only be applied to the front wheels. Stopping distance is increased!
Low brake fluid in the reservoir may cause the braking system to fail!
Possible solution 왘 Risk of accident! Stop the vehicle and notify an authorized Mercedes-Benz Center. Do not add brake fluid! This will not solve the problem.
Don’t add brake fluid before checking the brake system. Overfilling the brake fluid res- ervoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire. You can be seriously burned.
If you find that the brake fluid in the brake fluid reservoir has fallen to the minimum mark or below, have the brake system checked for brake pad thickness and leaks.
Brake pad thickness must be visually inspected by a qualified technician at the intervals specified in the Service Booklet.
