Care
245H
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 G
Risk of accident
The vehicle is braked when HOLD is activa-
ted. Therefore, deactivate HOLD before the
vehicle is washed in an automatic car wash.
You can wash the vehicle in an automatic car
wash from the very start.
! Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use one with high-pressure jets for
prewashing.
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 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 any
wax and drying agents off the windscreen and
the wiper blades. This will prevent smears and
reduce wiping noises caused by residue on
the windscreen.
High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with cir-
cular-jet nozzles (dirt grinders) to clean
your vehicle or - especially - the tyres. You
could otherwise damage the tyres and
cause an accident.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door joint
R electrical components Operation

Where will I find...?
254 Vehicle tool kit, jack and spare
wheel*
The vehicle tool kit is located in a stowage
compartment underneath the floor of the
boot/luggage compartment. G
Risk of injury
The jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed.
If you are carrying out work on the vehicle,
you must use stands.
Make sure that the jack is placed on a firm,
non-slip and level surface. Do not use
wooden blocks or similar objects as a jack
underlay. Otherwise, the jack will not be
able to achieve its load-bearing capacity
due to the restricted height.
Do not start the engine at any time while a
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the boot lid/tailgate is opened or closed)
and you could be seriously injured. i
When using the jack, you should also
observe the safety notes in the "Flat tyre"
section (Y page 324).
