G Warning!
Make sure no one is near the wheel housing
or under the vehicle when you lower the
vehicle while it is standing still. Limbs could
become wedged into or under the 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.
G Warning!
Please be aware that by raising the vehicle
level, the center of gravity also rises.
Therefore, always ensure that the vehicle
level is as low as possible. With higher ride
®
height the ESP may activate earlier in
certain situations.
Adapt your speed and driving to possible
changed driving behavior of the vehicle
after changing the vehicle level. The ESP
cannot prevent accidents, including those
resulting from excessive speed. The ESP
cannot prevent the natural laws of physics
from acting on the vehicle.
!
Keep in mind that in rough or uneven
terrain, adjusting the vehicle to a lower
level may cause the vehicle underbody to
come in contact with the ground and result
in damage to the vehicle underbody.
Always make sure the vehicle has sufficient
ground clearance before adjusting it to a
lower level.
!
Before jacking up the vehicle with
equipment that lifts one or more of the
wheels completely off of the ground,
remove the SmartKey from the starter
switch.
