Care
248 H
Environmental note
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally responsible manner.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces, otherwise you could
damage the paintwork. Vehicle care
! Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature.
Automatic car wash You can wash the vehicle in an automatic car
wash from the very start. !
Vehicles with an exterior spare wheel
bracket* must not be washed in an auto-
matic car wash.
! Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use one without brushes.
If the vehicle is very dirty, prewash it before
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise a risk of dam-
age to the exterior mirrors.
! Make sure that the automatic transmis-
sion is not in position Pwhen washing your
vehicle in an automatic car wash.
R Vehicles with a key:
Do not remove the key from the ignition
lock. Do not open the driver's or front-
passenger door when the engine is
switched off, as this automatically shifts
the automatic transmission to park posi-
tion Pand locks the wheels, unless you have shifted the automatic transmission
to
N.
R Vehicles with KEYLESS GO*:
Do not open the driver's or front-
passenger door when the engine is
switched off, as this shifts the automatic
transmission to park position Pand locks
the wheels.
! Make sure the side windows are com-
pletely closed, the ventilation/heater
blower is fully turned off and the wind-
screen wiper switch is set to 0. The rain
sensor may otherwise be activated, for
instance, leading to inadvertent wiper
sweeps being triggered. This could cause
damage to the vehicle.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen.
