Care
244 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. !
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.
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 Operation

Where will I find...?
252 Vehicle tool kit, jack, TIREFIT kit and
emergency spare wheel*
The vehicle tool kit, jack, TIREFIT kit and
emergency spare wheel* are in the stowage
compartment under the luggage compart-
ment floor. 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.
You must use stands if you are carrying out
work on the vehicle.
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 tailgate is opened or closed) and you
could be seriously injured. X
Open the tailgate.
X Open the luggage compartment floor
(Y page 250).
! If the luggage compartment cover* is fit-
ted, roll it open fully.
Only for luggage compartment covers* fit-
ted behind the 3rd row of seats:
Fold forwards the section of the luggage
compartment cover* that is still protrud-
ing. Otherwise the strap of the retaining
hook may damage the luggage compart-
ment cover*.
