then raise the vehicle using the jack, the pneu-
matic suspension attempts to compensate
the vehicle level. The jack could tip over.
There is a danger of injury.
Remove the key from the ignition lock before
raising the vehicle. This prevents automatic
readjustment of the vehicle level.

WARNING
Oiled, greased or damaged wheel nuts or
wheel bolt threads can cause the wheel nuts
to loosen or be damaged. As a result, you
could lose a wheel while driving. There is a risk
of an accident.
Never oil or grease the threads. In the event of
damage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel nuts or wheel bolts replaced.
Do not drive on.
G
WARNING
If you remove a wheel that is resting on the
wheel bolts under load, it may fall off or tip.
There is a risk of injury.
Remove the last three wheel nuts when it is
clear that the wheel is being held tension-free
on the wheel bolts.

WARNING
Wheel and tyre dimensions as well as the type
of tyre can vary between the spare wheel and
the wheel to be replaced. When the spare
wheel is fitted, driving characteristics may be
severely affected. There is a risk of an acci-
dent.
To prevent risks:
you should therefore adapt your driving
R
style and drive carefully.
never fit more than one spare wheel that
R
differs from the wheel to be replaced.
only use a spare wheel that differs from the
R
wheel to be replaced for a short time.
have a spare wheel that differs from the
R
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tyre dimensions as well as the wheel type.
! Do not raise vehicles equipped with a
loading crane or loading tailgate by using
the hydraulic supports. This would cause
damage to the chassis.
When changing a wheel:
only use wheel nuts that are approved for
R
your vehicle.
note that the wheel nuts for steel and light-
R
alloy wheels differ.
note that the wheel nuts for light-alloy
R
wheels on the front and rear axles differ.
note that wheels with a tyre pressure sen-
R
sor have a red ring on the tyre valve.
note that on vehicles with a tyre pressure
R
monitor, if the fitted wheel does not have a
tyre pressure sensor, an event window
appears in the display.
Observe the following notes when using the
jack to raise the vehicle:
the jack is designed only to raise the vehi-
R
cle for a short time, e.g. while a wheel is
being changed. It is not suitable for raising
and holding the vehicle so that work can be
carried out underneath it.
only position the jack at the appropriate
R
jacking point of the vehicle. Make sure that
the jack is correctly positioned on the jack-
ing point before raising the vehicle.
The jacking point may differ on special bod-
ies. Observe the operating instructions
issued by the body manufacturer.
secure the vehicle before raising it to pre-
R
vent it from rolling away, e.g. by applying
the parking brake and/or using chocks. Do
not release the parking brake while the
vehicle is raised.
the surface on which the jack is standing
R
must be firm and level. Place the jack on an
underlay if the surface is not firm.
make sure that the gap between the under-
R
side of the raised tyre and the ground does
