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 rec-
ommended and approved by Mercedes-Benz.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning 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 man-
ner.
! Do not park up 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 clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up. Care of the exterior
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, following a car wash, drive with
particular care until the brakes are dry.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic transmis-
sion is in position Nwhen washing your
vehicle in a tow-through car wash. The vehi-
cle could be damaged if the transmission is
in another position.
! Make sure that:
R the side windows and sliding sunroof are
closed completely.
R the blower for the ventilation/heating is
switched off (OFF button is depressed).
R the windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper Care
