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

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 †).

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.
