Vehicle level control
Your vehicle automatically adjusts its ride
height to increase vehicle safety and to
reduce fuel consumption.
i Changes to the vehicle level should be
made while the vehicle is moving. The
vehicle will then reach the set level as fast
as possible.
The vehicle begins adjusting to the set vehicle
level as soon as the doors or tailgate are
unlocked or opened or closed with the vehicle
unlocked.
For major changes in vehicle level, the engine
must be running.

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.
! Keep in mind that on rough or uneven
roads, 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 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.
i The activation threshold is defined by the
