Care Notes on care Regular care of your vehicle is a condition for retaining the quality in the long term.

Use care products and cleaning agents recommended and approved by Mercedes- Benz. 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. 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.

Care 415

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. ! It is preferable to use car washes with

adjustable21 high-pressure precleaning. In car washes that use high water pressures, there is a risk that a small amount of water may leak into the vehicle.

! 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. ! In car washes with a towing mechanism, make sure that the automatic transmission is in transmission position N, otherwise the vehicle could be damaged. RVehicles with a SmartKey:

Do not remove the SmartKey from the ignition lock. Do not open the driver's door or front-passenger door when the engine is switched off. Otherwise, the automatic transmission selects park position P automatically and locks the wheels. You can prevent this by shifting

the automatic transmission to N beforehand.

RVehicles with KEYLESS-GO:

Do not open the driver's door or front- passenger door when the engine is switched off. Otherwise, the automatic transmission selects park position P automatically and locks the wheels.

Observe the following to make sure that the automatic transmission stays in position N: X Make sure the vehicle is stationary and the

ignition is switched off.

X Turn the SmartKey to position

2 (Y page 267) in the ignition lock. Use the SmartKey instead of the Start/ Stop button on vehicles with KEYLESS-GO.

X Depress and hold the brake pedal. X Shift the automatic transmission to

position N.

X Release the brake pedal. X Release the electric parking brake. X Switch off the ignition and leave the

SmartKey in the ignition lock.

! 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 Carefully remove all deposits of road salt as soon as possible when driving in winter.

21 Corresponds to the specification for the Cabriolet program.

416 Care

Also, clean the insides of the wheels when washing the underbody of the vehicle. X Do not use hot water and do not wash the

vehicle in direct sunlight.

X Use a soft car sponge for cleaning. X Use a gentle cleaning agent, e.g. a

Mercedes-Benz approved car shampoo.

X Wash down the vehicle with a gentle water

jet.

X Do not point the water jet directly at the air

inlets.

X Use plenty of water and rinse the sponge

frequently.

X Rinse the vehicle with clean water and dry

it thoroughly with a chamois.

X Do not allow the cleaning agent to dry on

the paintwork.

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.

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.

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.
