compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts

!Do not park your vehicle for a long period oftime directly after cleaning, particularly aftercleaning the wheel rim with wheel cleaner.Wheel cleaner can lead to the increased cor-rosion of the brake discs and pads. Therefore,drive for a few minutes after cleaning. Byheating up the brakes, the brake discs andpads dry. The vehicle can then be parked for along period of time.
HEnvironmental note

Rthe side windows and sliding sunroof areclosed completely
Rthe blower is switched off
Rthe windshield wiper switch is in position

Do not remove the SmartKey from the igni-tion lock. Do not open the driver's doorwhen the engine is switched off or at verylow speeds. Otherwise, when in transmis-sion position[or^, the automatictransmission will automatically switch topark position]and block the wheels.
ROperating with the Start/Stop button:
Do not open the driver's door when theengine is switched off or at very lowspeeds. Otherwise, when in transmissionposition[or^, the automatic transmis-sion will automatically switch to park posi-tion]and block the wheels.
Observe the following to make sure that theautomatic transmission stays in neutral\\:

You can wash the vehicle in an automatic carwash from the very start.
If the vehicle is very dirty, pre-wash it beforecleaning it in an automatic car wash.
After using an automatic car wash, wipe off waxfrom the windshield and the wiper blades. Thiswill prevent smears and reduce wiping noisescaused by residue on the windshield.
Washing by hand
In some countries, washing by hand is onlyallowed at specially equipped washing bays.Observe the legal requirements in each country.
XDo not use hot water and do not wash thevehicle in direct sunlight.
XUse a soft sponge to clean.
XUse a mild cleaning agent, such as a carshampoo approved by Mercedes-Benz.

XDo not point the water jet directly towards theair inlet.
XUse plenty of water and rinse out the spongefrequently.
XRinse the vehicle with clean water and drythoroughly with a chamois.
XDo not let the cleaning agent dry on the paint-work.
Carefully remove all deposits of road salt assoon as possible when driving in winter.
Power washers
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Always maintain a distance of at least 12 in(30 cm) between the vehicle and the powerwasher nozzle. Information about the correctdistance is available from the equipmentmanufacturer.
Move the power washer nozzle around whencleaning your vehicle.
Do not aim directly at any of the following:
RTires
RDoor gaps, roof gaps, joints, etc.
RElectrical components
RBattery
RPlug-type couplings
306Care
Maintenance and care

RLight bulbs
RSeals
RTrim elements
RVentilation slots
Damaged seals or electrical components canlead to leaks or failures.
!Vehicles with decorative film: parts of yourvehicle are covered with decorative film.Maintain a distance of at least 27.5 in (70 cm)between the film-covered parts of the vehicleand the nozzle of the power washer.
Information about the correct distance isavailable from the equipment manufacturer.
Move the power washer nozzle around whencleaning your vehicle.
The water temperature of the power washermust not exceed 140 ‡ (60 †).
!If the SmartKey is within the rear detectionrange of KEYLESS-GO, the following situa-tions, for example, could lead to the uninten-tional opening of the tailgate:
Rwhen using an automatic car wash
Rwhen using a power washer
Make sure that the SmartKey is at least 10 ft(3 m) away from the vehicle.
Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic plates or similar items
to painted surfaces. You could otherwisedamage the paintwork.
Scratches, corrosive deposits, areas affected bycorrosion and damage caused by inadequatecare cannot always be completely repaired. Insuch cases, visit a qualified specialist workshop.
XRemove dirt immediately, where possible,while avoiding rubbing too hard.
XSoak insect remains with insect remover andrinse off the treated areas afterwards.
XSoak bird droppings with water and rinse offthe treated areas afterwards.
XRemove tree resin, oils, fuels and greases byrubbing gently with a cloth soaked in petro-leum ether or lighter fluid
XRemove coolant and brake fluid with a moistcloth and clear water.
XUse tar remover to remove tar stains.
XUse silicone remover to remove wax.
When water no longer forms beads on the paintsurface, use the care product Paint Care, whichhas been approved for Mercedes-Benz. This isthe case approximately every three to fivemonths, depending on the climate conditionsand the care product used.
The cleaning product Paint Cleaner, which hasbeen recommended and approved forMercedes-Benz, should be used when dirt haspenetrated the paint surface.
Also use Paint Cleaner on paint that has becomedull.
Do not use these care products in the sun or onthe hood while the hood is hot.
XUse a suitable touch-up stick, e.g. MB Touch-Up Stick, to repair slight damage to the paint-work quickly and provisionally.
Matte finish care
!Never polish the vehicle or the light alloywheels. Polishing causes the finish to shine.
!The following can give the paint a glossyappearance and thus reduce the matt effect:
RRubbing hard with unsuitable agents
RWashing the vehicle in direct sunlight
!Never use paint cleaner, buffing or polishingproducts, or gloss preserver, e.g. wax, for thepurpose of paintwork care. These productsare only suitable for high-gloss surfaces. Theiruse on vehicles with matte paintwork leads toconsiderable surface damage or, more spe-cifically, to shiny, spotted areas.
Always have paintwork repairs carried out at aqualified specialist workshop.
!Only use automatic car washes which cor-respond to the latest technological stand-ards. Never use wash programs which finishby treating the vehicle with hot wax.
Observe these notes if your vehicle has a clearmatte finish. This will help you to avoid damageto the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels witha clear matte finish.
Use only insect remover and car shampoo fromthe range of approved Mercedes-Benz careproducts.
