Operation Maintenance
If the battery is disconnected, the days of disconnection will not be included in the count shown by the maintenance service indicator. To arrive at the true maintenance service deadline, you will need to subtract these days from the days shown in the maintenance service indicator message or maintenance ser- vice indicator display. Do not confuse the maintenance service indicator with the engine oil level indicator N.
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.
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 under- body 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. 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 applied later.
341
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.
342
Power washer
Paintwork, painted body components
Follow the instructions provided by the power washer manufacturer on main- taining 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 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.
Affixing stickers, adhesive tape or sim- ilar materials to painted body compo- nents 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, de- pending on the climate and washing deter- gent 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.).
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 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 dif-
fused 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.
Operation Vehicle care
Automatic car wash You can have your car washed in an auto- matic car wash from the start. Automatic car washes without brushes are prefera- ble.
Do not clean your vehicle in an auto- matic touchless car wash which uses caustic spray. Otherwise the caustic spray will damage the paint or orna- mental moldings.
If the vehicle is very dirty, prewash it be- fore running it through the automatic car wash.
343
Operation Vehicle care
Due to the width of the vehicle, fold in exterior rear view mirrors prior to run- ning the vehicle through an automatic car wash to prevent damage to the mirrors. Make sure that the windshield wiper switch is set to 0 (컄 page 50). Other- wise, the rain sensor could activate and cause the wipers to move unintention- ally. This may lead to vehicle damage.
After running the vehicle through an au- tomatic car wash, wipe any wax off of the windshield (컄 page 345). 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. Other- wise they may vibrate.
344
Ornamental moldings For regular cleaning and care of ornamen- tal 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 orna- mental moldings. Although ornamental moldings may have chrome appear- ance, they could be made of anodized aluminum that will be damaged when cleaned with chrome cleaner. Instead, use a damp cloth to clean those orna- mental 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 Sham- poo, with plenty of water.
Only use window cleaning solutions that are suitable for plastic lamp lens- es. Window cleaning solutions which are not suitable may damage the plas- tic lamp lenses of the headlamps. Therefore, do not use abrasives, sol- vents or cleaners that contain solvents. Never apply strong force and only use a soft, non-scratching cloth when clean- ing the lenses. Do not attempt to wipe dirty lenses with a dry cloth or sponge. Otherwise you may scratch or damage the lens surface.
Cleaning the windows and the wiper blades
Warning!
The windshield wipers must be in a ver- tical position before folding them away from the windshield. They could other- wise damage the hood. Never open the hood when the wiper arms are folded forward.
왘 Switch on the ignition (컄 page 33). 왘 Turn combination switch to wiper
setting II (컄 page 50).
왘 With wiper arms in vertical position,
switch off the ignition (컄 page 33).
For safety reasons, switch off wipers and re- move 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.
왘 Clean the wiper blade inserts with a
clean cloth and detergent solution.
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.
Operation Vehicle care
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.
345
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 al- loy 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 corro- sion of the brake disks and brake pads. 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.
346
Hard plastic trim items 왘 Use Mercedes-Benz approved Interior Care, a soft, lint-free cloth and apply with light pressure.
To prevent scratches, do not use scour- ing agents.
Steering wheel and gear selector lever 왘 Wipe with a damp cloth and dry thor- oughly or clean with Mercedes-Benz approved Leather Care.
Carpets 왘 Use Mercedes-Benz approved Carpet and Fabric Care for cleaning the car- pets.
When applying Mercedes-Benz ap- proved Tire Care and Mercedes-Benz approved Wheel Care products, take care not to spray them on the brake disks.
Plastic and rubber parts 왘 Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution.
Do not use oil or wax on these parts.
Instrument cluster and cup holders 왘 Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution.
왘 Wipe with a cloth moistened in a luke-
warm solution.
To prevent scratches, do not use scour- ing agents.
Headliner and shelf below rear window 왘 Use a soft bristle brush or a dry-sham- poo cleaner in case of excessive dirt.
Seat belts 왘 Only use clear, lukewarm water and
soap.
The webbing must not be treated with chemical cleaning agents. 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.
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 왘 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.
Operation Vehicle care
MB Tex upholstery 왘 Use Mercedes-Benz approved Interior Care onto a soft, lint-free cloth and ap- ply with light pressure for cleaning the upholstery.
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.
