Do not confuse the maintenance service indicator with the engine oil level indicator 4.

Resetting the maintenance service indicator In the event that the maintenance service on your vehicle is not carried out at 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 literature for your vehicle. Such literature is available at any authorized Mercedes-Benz Center or directly from Mercedes-Benz. ! If the maintenance service indicator was

reset inadvertently, have an authorized Mercedes-Benz Center correct it. Only reset the maintenance service indicator if the proper maintenance service has been performed. Not following the proper maintenance service as described in the Maintenance Booklet will result in engine damage and/or other vehicle damage not covered by the Mercedes-Benz Limited Warranty.

Vehicle care Cleaning and care of the vehicle Notes Regular and proper care will help to maintain the value of your vehicle. G Warning! Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the particular container. Always open your

219_AKB; 4; 54, en-US d2ureepe,

216 Vehicle care

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.

! When cleaning the vehicle, do not use

scouring agents. Never apply strong force and only use a soft, wet cloth or sponge. Otherwise you may scratch or damage the surface to be cleaned.

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: RAir pollution RRoad salt RTar RGravel and stone chipping To avoid paint damage, you should immediately remove: RGrease and oil RFuel RCoolant RBrake fluid RBird droppings RInsects RTree resins etc. Frequent washing reduces and/or eliminates the aggressiveness and potency of the above adverse influences.

2009-05-11T16:21:02+02:00 - Seite 216
Version: 2.11.8.1

More frequent washings are necessary to deal with unfavorable conditions: Rnear the ocean Rin industrial areas (smoke, exhaust

emissions)

Rduring 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. 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 vehicle-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 vehicle-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 vehicle-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 vehicle-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.

i Vehicles with KEYLESS-GO:

If a door handle is hit by a strong jet of water, and a SmartKey is within approximately 3 ft (1 m) of the vehicle, it could be inadvertently locked or unlocked.

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. X Use the appropriate MB-Touch-Up Stick for quick and provisional repairs of minor paint

Vehicle care 217

damage (i.e. chips from stones, vehicle doors, etc.).

Vehicles with mat paint Your vehicle is painted with mat clear-coat paint. Observe the following notes to avoid paint damage caused by improper treatment. i Only use insect remover and car shampoo

approved by Mercedes-Benz.

! Do not polish the vehicle. Polishing will

brighten the paintwork. Do not use paintwork cleaning agents, abrasives, polishing compounds, or wax for paintwork care. Such products are intended for use on high-polish surfaces. Using such products on mat paint causes severe damage, such as bright, spotted areas on the respective surface. Have paintwork repairs performed at an authorized Mercedes-Benz Center.

Have stone chipping repairs as soon as possible. Remove the following immediately if possible. Do not apply strong force. RSoak insect remains with insect remover and rinse them of with water afterwards. Use a soft bristle toothbrush for remains that have not come off.

RSoak bird droppings with water and rinse them of with water afterwards. Use a soft bristle toothbrush for remains that have not come off.

RRemove tree resins, grease, oil, and

gasoline with silicone remover.

RDab off wax with silicone remover. RDab off tar splashes or tar stains with tar

remover.

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. i Vehicles with KEYLESS-GO:

If a door handle is hit by a strong jet of water, and a SmartKey is within approximately 3 ft (1 m) of the vehicle, it could be inadvertently locked or unlocked.

Hand-wash X Do not use hot water or wash your vehicle

in direct sunlight.

X Only use a soft, wet cloth or sponge to

clean the vehicle.

X Only use a mild vehicle wash detergent,

such as Mercedes-Benz approved Car Shampoo.

X Thoroughly spray the vehicle with a

diffused jet of water.

X Do not spray directly towards the

ventilation intake.

X Use plenty of water and rinse the sponge

and chamois frequently.

X Rinse with clean water and dry with a

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

Automatic car wash You can have your vehicle washed in an automatic car wash from the start. Brushless car washes are preferable. X To protect the filter system, activate the air recirculation mode using button g on the climate control panel.

! Do not clean your vehicle in an automatic

touchless car wash which uses caustic spray. 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. ! Make sure the combination switch is set to wiper setting $. Otherwise, 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.

X When taking the vehicle through an automatic conveyor-type car wash: Make sure the automatic transmission remains in neutral position N.

When leaving the automatic car wash, make sure the mirrors are folded out. After running the vehicle through an automatic car wash, wipe any wax off of the windshield and the wiper blade inserts. This will prevent smears and reduce wiping noise which can be caused by residual wax on the windshield.

Ornamental moldings X For regular cleaning and care of ornamental

moldings, use a damp cloth.

! 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.

An automotive glass cleaner is recommended.

! Fold the windshield wiper arms back onto the windshield before turning the SmartKey in the starter switch or pressing the KEYLESS-GO start/stop button. 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 windows with hard objects such as an ice scraper or ring. Doing so may damage the windows.

Light alloy wheels If possible, clean wheels once a week. X 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. This applies especially 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 vehicle is not driven after cleaning. Therefore, the vehicle’s brake system should always be warmed-up before it is parked after cleaning. 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.

Display messages Check Tires

Possible causes/consequences and X Solutions Vehicles with Advanced TPMS (Canada only): The tire inflation pressure in at least one tire is significantly below the reference value. The respective tire is indicated in the multifunction display. X Carefully bring the vehicle to a halt, avoiding abrupt

steering and braking maneuvers.

X Check and adjust tire inflation pressure as required. X If necessary, change the wheel (Y page 271).

G Warning! Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up and possibly a fire.

G Warning! Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.
