Make sure that no one is near the wheel
housing or under the vehicle when you lower
the vehicle while it is standing still. Limbs

vehicle.
For safety reasons, the vehicle can only be
lowered with all doors and the tailgate
closed. Lowering is interrupted if a door or
the tailgate is opened and will continue after
the door is closed again.

Adapt your speed and driving to possible
changed driving behavior of the vehicle after
changing the vehicle level. The ESP

prevent accidents, including those resulting
from excessive speed. The ESP

cannot
prevent the natural laws of physics from
acting on the vehicle.

adjusting the vehicle to a lower level may cause
the vehicle underbody to come in contact with
the road and result in damage to the vehicle un-
derbody. Always make sure the vehicle has suffi-
cient ground clearance before adjusting it to a
lower level.
