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.

i If the maintenance service indicator was in- advertently 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 Warran- ty.

왔 Vehicle care Cleaning and care of the vehicle

Regular and proper care will help to maintain the value of your vehicle. The best way to protect your vehicle from harmful environmental influences is to wash it and use protective treatments reg- ularly.

Warning!

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

Never use fluids or solvents that are not designed for cleaning your vehicle.

Always lock away cleaning products and keep them out of reach of children.

While in operation, even while parked, your vehicle is subjected to varying external influences which, if gone unchecked, can attack the paintwork as well as the vehicle underbody and cause lasting damage. Such damage is caused not only by extreme 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 immediately remove: 앫 Grease and oil 앫 Fuel 앫 Coolant 앫 Brake fluid 앫 Bird droppings 앫 Insects 앫 Tree resins, etc.

Operation Vehicle care

Frequent washing reduces and/or eliminates 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 thorough check is a washing of the underbody followed by a thorough inspection. Damaged areas need to be re-undercoated.

313

Operation Vehicle care

Your vehicle has been treated at the factory 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 applied 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 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.

Power washer

! Follow the instructions provided by the power washer manufacturer on maintaining a distance between the vehicle and the nozzle of the power washer. 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 connectors, 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

! Affixing stickers, magnets, adhesive tape or similar materials to painted body components may damage the paintwork.

Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not “bead up”. This should normally be done every 3 to 5 months, depending on the 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. 왘 Use the appropriate MB-Touch-Up

Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehicle doors, etc.).

314

Engine cleaning Prior to cleaning the engine compartment, make sure to protect electrical components and connectors from contact with water and cleaning agents. Corrosion protection, such as MB Anticorrosion Wax, should be applied to the engine compartment after every engine cleaning. Before applying, all control linkage bushings and joints should be lubricated. The poly-V-belt and all pulleys should be protected from any wax.

Vehicle washing In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the vehicle underbody, do not forget to clean the inner sides of the wheels.

Hand-wash Do not use hot water or wash your vehicle in direct sunlight. 왘 Only use a mild car wash detergent,

such as Mercedes-Benz approved Car Shampoo.

왘 Thoroughly spray the vehicle with a

diffused jet of water. Direct only a very weak spray towards the ventilation intake.

왘 Use plenty of water and rinse the sponge and chamois frequently.

왘 Rinse with clean water and thoroughly

dry with a chamois. Do not allow cleaning agents to dry on the finish.

! Do not use scouring agents on these parts. Never apply strong force and only use a soft, non-scratching cloth when cleaning the vehicle. Do not attempt to wipe the surface with a dry cloth or sponge. Otherwise you nay scratch or damage the paint.

Operation Vehicle care

Automatic car wash You can have your car washed in an automatic car wash from the start. Automatic car washes without brushes are preferable. 왘 To protect the filter system, switch the

climate control or automatic climate control to air recirculation mode, see “Air recirculation” (컄 page 165) for climate control or (컄 page 175) for automatic climate control.

! Do not clean your vehicle in an automatic touchless car wash which uses caustic spray. Otherwise the caustic spray will damage the paint or ornamental moldings.

If the vehicle is very dirty, prewash it before running it through the automatic car wash.

315

Operation Vehicle care

! Make sure that the windshield wiper switch is set to 0 (컄 page 51). Otherwise, e.g. the rain sensor could activate and cause the wipers to move unintentionally. This may lead to vehicle damage. Due to the width of the vehicle, fold in exterior rear view mirrors prior to running the vehicle through an automatic car wash to prevent damage to the mirrors.

i After running the vehicle through an automatic car wash, wipe any wax off of the windshield (컄 page 317). This will prevent smears and reduce wiping noise which can be caused by residual wax on the windshield. When leaving the car wash, make sure that the mirrors are folded out. Otherwise they may vibrate.

Ornamental moldings For regular cleaning and care of ornamental moldings, use a damp cloth.

Headlamps, tail lamps, side markers, turn signal lenses 왘 Use a mild car wash detergent, such as

! Do not use chrome cleaner on ornamental moldings. Although ornamental moldings may have chrome appearance, they could be made of anodized aluminum that will be damaged when cleaned with chrome cleaner. Instead, use a damp cloth to clean those ornamental moldings. For very dirty ornamental moldings of which you are sure are chrome-plated, use a chrome cleaner. If in doubt whether an ornamental molding is chrome-plated, contact an authorized Mercedes-Benz Center.

Mercedes-Benz approved Car Shampoo, with plenty of water.

! Only use window cleaning solutions that are suitable for plastic lamp lenses. Window cleaning solutions which are not suitable may damage the plastic lamp lenses of the headlamps. Therefore, do not use abrasives, solvents or cleaners that contain solvents. Never apply strong force and only use a soft, non-scratching cloth when cleaning the lenses. Do not attempt to wipe dirty lenses with a dry cloth or sponge. Otherwise you may scratch or damage the lens surface.

316

왘 Use a soft, clean cloth and a mild win-

dow cleaning solution on all outside and inside glass surfaces. An automotive glass cleaner is recom- mended.

! Fold the windshield wiper arms back onto the windshield before turning the SmartKey in the starter switch. Hold on to the wiper when folding the wiper arm back. If released, the force of the impact from the tensioning spring could crack the windshield.

! To clean the window interior, do not use a dry cloth, abrasives, solvents or cleaners containing solvents. Do not touch the inside of the front, rear or side windows with hard objects such as an ice scraper or ring. Doing so may damage the windows.

Cleaning the windows and the wiper blades

! Never open the hood when the wiper arms are folded forward. 왘 Make sure the hood is fully closed. 왘 Switch off the ignition (컄 page 32).

Warning!

For safety reasons, switch off wipers and remove SmartKey from starter switch before cleaning the windshield and/or the wiper blades. Otherwise, the wiper motor could suddenly turn on and cause injury.

왘 Fold the wiper arms forward until they

snap into place.

! Do not pull on the wiper blade inserts. They could tear. 왘 Clean the wiper blade inserts with a

clean cloth and detergent solution.

Operation Vehicle care

Light alloy wheels If possible, clean wheels once a week. 왘 Use Mercedes-Benz approved Wheel Care, a soft bristle brush and a strong spray of water for cleaning the light alloy wheels.

! Only use acid-free cleaning materials. Acid may cause corrosion or damage the clear coat.

! The vehicle should not be parked for an extended period of time immediately after it has been cleaned, especially not after the wheel rims have been cleaned with wheel rim cleaner. Wheel rim cleaners can lead to increased corrosion of the brake disks and brake pads. Non-approved wheel cleaners may also damage the wheel paint if the car is not driven after cleaning. Therefore, the vehicle’s brake system should always be warmed-up before it is parked after cleaning. To do so, please drive your vehicle for several minutes to allow the brakes to dry. When applying Mercedes-Benz approved Tire Care and Mercedes-Benz approved Wheel Care products, take care not to spray them on the brake disks.

317

! Do not use oil, wax or scouring agents on these parts. Never apply strong force and only use a soft, non-scratching cloth when cleaning the surface. Do not attempt to wipe the surface with a dry cloth or sponge. Otherwise you may scratch or damage the surface.

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

! Never apply strong force and only use a soft, non-scratching cloth when cleaning the surface. Do not attempt to wipe the surface with a dry cloth or sponge. Otherwise you may scratch or damage the surface.

Operation Vehicle care

Plastic and rubber parts 왘 Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution.

왘 Wipe with a cloth moistened in a

lukewarm solution. The surface may temporarily change color. If this is the case, wait for it to dry.

Warning!

Do not use cleaners or cockpit care sprays containing solvents to clean the cockpit or the steering wheel. Cleaners containing sol- vents will make the surface porous and vehi- cle occupants could suffer serious injuries from plastic parts coming loose in the event of air bag deployment.

! The seat belts must not be treated with chemical cleaning agents. Do not dry the seat belts 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.

319

Wood trims 왘 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 discolored. By lining the seats with a proper intermediate cover, contact-discoloration will be prevented.

Warning!

Only use seat or head restraint covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using other seat or head restraint covers may interfere with or prevent the activation of the active head restraints. Contact an authorized Mercedes-Benz Center for availability.

320

Leather upholstery Please note that leather upholstery is a natural product and is therefore subject to a natural aging process. Leather upholstery may also react to certain ambient influences such as high humidity or high temperature by showing wrinkles for example. 왘 Wipe leather upholstery with a damp cloth and dry thoroughly or clean with Mercedes-Benz approved Leather Care.

! Wipe with light pressure to avoid damage to the upholstery.

Exercise particular care when cleaning perforated leather as its underside should not become wet.

MB Tex upholstery 왘 Use Mercedes-Benz approved Interior

Care onto a soft, lint-free cloth and apply with light pressure for cleaning the upholstery.

Possible cause/ consequence

Possible solution

Monitor the 56 indicator lamp on the center console (컄 page 27) and the mul- tifunction display in the instrument cluster (컄 page 24) for the following: With the seat unoccupied and the ignition turned on, 앫 the 56 indicator lamp on the center console should illuminate and remain

illuminated, indicating that the OCS (컄 page 64) has deactivated the air bag.

앫 the message Front-pass. airbag enabled See Operator’s Manual or the mes- sage Front-pass. airbag disabled See Operator’s Manual should not appear in the multifunction display at any time the seat is unoccupied. Wait at last 60 sec- onds for the system to complete the necessary check cycles and to make sure neither message appears in the multifunction display.

If above conditions are met, you can occupy the front passenger seat again. Depend- ing on the front passenger classification sensed by the OCS (컄 page 64), the 56 indicator lamp will remain illuminated or go out. If above conditions are not met, the system is not working properly. Have the system checked as soon as possible by an authorized Mercedes-Benz Center.

Warning!

If the 56 indicator lamp remains

illuminated with an adult occupant on the front passenger seat even after performing the above corrective steps, do not have any

passenger use the front passenger seat until the system has been repaired.
