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 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.

! For cleaning your vehicle, do not use any

of the following: Rdry, rough or hard cloths Rabrasive cleaning agents Rsolvents Rcleaning agents containing solvents Do not scrub. Do not touch the surfaces or protective films with hard objects, e.g. a ring or ice scraper. You could otherwise scratch or damage the surfaces and protective film.

270 Care

H Environmental note Dispose of empty packaging and cleaning cloths in an environmentally responsible manner.

! Do not park the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after cleaning. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked.

Exterior care Automatic car wash G WARNING Braking efficiency is reduced after washing the vehicle. This could cause an accident. For this reason, you must drive particularly carefully after washing the vehicle until the brakes have dried. G WARNING The vehicle is braked when the HOLD function or DISTRONIC PLUS is activated. Therefore, deactivate the HOLD function and DISTRONIC PLUS before the vehicle is washed in an automatic car wash.

You can wash the vehicle in an automatic car wash from the very start. ! Never clean your vehicle in a Touchless Automatic Car Wash as these use special cleaning agents. These cleaning agents can damage the paintwork or plastic parts.

If the vehicle is very dirty, pre-wash it before cleaning it in an automatic car wash. ! Make sure that the automatic

transmission is in position N when washing your vehicle in a tow-through car wash. The

vehicle could be damaged if the transmission is in another position.

! Make sure that:

Rthe side windows and the sliding sunroof

are fully closed.

Rthe ventilation/heating is switched off

(the OFF button has been pressed).

Rthe windshield wiper switch is in position

0.

Otherwise, the vehicle might be damaged. After using an automatic car wash, wipe off wax from the windshield and the wiper blades. This will prevent smears and reduce wiping noises caused by residue on the windshield.

Washing by hand In some countries, washing by hand is only allowed at specially equipped washing bays. Observe the legal requirements in all countries concerned. X Do not use hot water and do not wash the

vehicle in direct sunlight.

X Use a soft sponge to clean. X Use a mild cleaning agent, such as a car shampoo approved by Mercedes-Benz.

X Thoroughly hose down the vehicle with a

gentle jet of water.

X Do not point the water jet directly towards

the air inlet.

X Use plenty of water and rinse out the

sponge frequently.

X Rinse the vehicle with clean water and dry

thoroughly with a chamois.

X Do not let the cleaning agent dry on the

paintwork.

When using the vehicle in winter, remove all traces of road salt deposits carefully and as soon as possible.

Power washers G WARNING Do not use power washers with circular-jet nozzles (dirt grinders) to clean your vehicle, in particular the tires. You could otherwise damage the tires and cause an accident.

! Always maintain a distance of at least

11.8 in (30 cm) between the vehicle and the power washer nozzle. Information about the correct distance is available from the equipment manufacturer. Move the power washer nozzle around when cleaning your vehicle. Do not aim directly at any of the following: Rtires Rdoor gaps, roof gaps, joints etc. Relectrical components Rbattery Rconnectors Rlights Rseals Rtrim elements Rventilation slots Damaged seals or electrical components can lead to leaks or failures.

Cleaning the wheels ! Do not use acidic wheel cleaning products to remove brake dust. This could damage wheel bolts and brake components.

! Do not park the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after cleaning. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked.

Care 271

Cleaning the paintwork Scratches, corrosive deposits, areas affected by corrosion and damage caused by inadequate care cannot always be completely repaired. In such cases, visit a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. X Remove impurities immediately, where

possible, whilst avoiding rubbing too hard. X Soak insect remains with insect remover and rinse off the treated areas afterwards. X Soak bird droppings with water and rinse

off the treated areas afterwards.

X Remove coolant, brake fluid, tree resin, oils, fuels and greases by rubbing gently with a cloth soaked in petroleum ether or lighter fluid.

X Use tar remover to remove tar stains. X Use silicone remover to remove wax. ! Do not affix:

Rstickers Rfilms Rmagnetic plates or similar items to painted surfaces. You could otherwise damage the paintwork.

If water no longer forms "beads" on the paint surface, use the paint care products recommended and approved by Mercedes- Benz. This is the case approximately every three to five months, depending on the climate conditions and the care product used. If dirt has penetrated the paint surface or the paint has become dull, the paint cleaner recommended and approved by Mercedes- Benz should be used. Do not use these care products in the sun or on the hood while the hood is hot. X Use a suitable touch-up stick, e.g. MB

Touch-Up Stick, to correct smaller areas of paint damage quickly and provisionally.

272 Care

Matte finish care If your vehicle has a clear matte finish, observe the following instructions in order to avoid damage to the paintwork due to incorrect care. These notes also apply to light alloy wheels with a clear matte finish. ! Never polish the vehicle or the light alloy

wheels. Polishing causes the finish to shine.

! The following may cause the paint to

become shiny and thus reduce the matte effect: RVigorous rubbing with unsuitable

materials.

RFrequent use of car washes. RWashing the vehicle in direct sunlight.

! Never use paint cleaner, buffing or

polishing products, or gloss preserver, e.g. wax. These products are only suitable for high-gloss surfaces. Their use on vehicles with matte finish leads to considerable surface damage (shiny, spotted areas). Always have paintwork repairs performed at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

! Do not use wash programs with a hot wax

treatment under any circumstances.

i The vehicle should preferably be washed by hand using a soft sponge, car shampoo and plenty of water.

i Use only insect remover and car shampoo

from the range of recommended and approved Mercedes-Benz care products.

X On downhill gradients: place chocks or other suitable items in front of the wheels of the front and rear axle.

Raising the vehicle G WARNING When jacking up the vehicle, only use the jack which has been specifically approved by Mercedes-Benz for your vehicle. The jack is designed exclusively for jacking up the vehicle at the jacking points built into both sides of the vehicle. The jack saddle must be placed centrally under the jacking point. The jack must always be vertical when in use, especially on inclines or declines. The jack is intended only for lifting the vehicle briefly for wheel changes. It is not suited for performing maintenance work under the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle. Always firmly engage the parking brake and block the wheels with wheel chocks or other sizable objects before raising the vehicle with the jack. Do not disengage the parking brake while the vehicle is raised. Make sure that the ground on which the vehicle is standing and where you place the jack is solid, level and not slippery. If necessary, use a large underlay. On slippery surfaces, such as tiled floors, you should use a non-slip underlay, for example a rubber mat. Do not use wooden blocks or similar objects as a jack underlay. Otherwise, the jack may not be able to achieve its load-bearing capacity if it is not at its full height. Never start the engine when the vehicle is raised. Also observe the notes on the jack.
