WARNING Risk of injury due to the jack
tipping over
If you park a vehicle with air suspension, the
air suspension can remain active for up to an
hour, even if the vehicle is switched off. If you
then raise the vehicle using the jack, the air
suspension will attempt to even out the vehicle
level.
The jack can tip over.
#
Before raising the vehicle, press the
Service button on the remote control for
the air suspension.
This prevents the vehicle level from being
automatically readjusted or manually
raised or lowered.
&
WARNING Risk of injury from incorrect
positioning of the jack
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip with the vehicle raised.
#
Only position the jack at the appropriate
jacking point of the vehicle. The base of
the jack must be positioned vertically
under the jacking point of the vehicle.
&
WARNING Risk of injury from vehicle tip-
ping
On slopes, the jack could tip with the vehicle
raised.
#
Never change a wheel on a slope.
#
Consult a qualified specialist workshop.
