Raising the vehicle when changing a wheel
& WARNING Risk of injury from jack tip‐
ping
If you park a vehicle with air suspension, the
air suspension may remain activated for up to
one hour, even when the ignition is switched
off. If you then raise the vehicle with the jack,
the air suspension will attempt to adjust the
vehicle level.
The jack may tip.
Press the Service button on the air sus‐
#
pension remote control before raising
the vehicle.
This prevents automatic readjustment
of the vehicle level and prevents it from
being raised or lowered manually.
& 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.
#
* NOTE Vehicle damage from the jack
If you do not position the jack correctly at the
appropriate jack support point of the vehicle,
the jack could tip over with the vehicle raised.
The jack is designed exclusively for
#

port points.
