Operation Maintenance

Resetting the maintenance service indicator

In the event that the maintenance service on your vehicle is not carried out by an authorized Mercedes-Benz Center, you can have the maintenance service indicator reset. The automotive maintenance facility carrying out the maintenance service will find the information for resetting the maintenance service indicator in the maintenance-relevant information for your vehicle. Such information is available from either your authorized Mercedes-Benz Center or directly from Mercedes-Benz.

If the maintenance service indicator was inadvertently reset, have an authorized Mercedes-Benz Center correct it. Only reset if the proper maintenance service has been performed. Resetting the system without performing the proper service as called for by the maintenance service indicator will result in engine damage and/or other vehicle damage not covered by the Mercedes-Benz Limited Warranty.

왔 Vehicle care Cleaning and care of the 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 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.

Operation Vehicle care

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.

333

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 an 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 an 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 products.

334

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.

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, vehicle doors, etc.).

Engine cleaning Prior to cleaning the engine compartment make sure to protect electrical compo- nents and connectors from the intrusion of water and cleaning agents. Corrosion protection, such as MB Anticor- rosion Wax, should be applied to the en- gine compartment after every engine cleaning. Before applying, all control link- age bushings and joints should be lubricat- ed. The poly-V-belt and all pulleys should be protected 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. Due to the width of the vehicle, fold in ex- terior rear view 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 forget to clean the inner sides of the wheels.

Operation Vehicle care

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 attempt to wipe dirty lenses with a dry cloth or sponge.

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.

337

MB Tex upholstery 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.

Wood trims Dampen cloth using water and use damp cloth to clean wood trims in your vehicle. Do not use solvents like tar remover or wheel cleaner nor polishes or waxes as these may be abrasive.

Operation Vehicle care

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.

Leather upholstery 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.
