the speed increases. As the vehicle
decelerates, the vehicle is raised back up to
highway level. In
ADS SPORT( Y page 195),
the vehicle skips highway level and is lowered
directly to high-speed level.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle
to adjust to the new level as quickly as
possible.
The vehicle level may change visibly when you
park the vehicle and the outside temperature
changes. When the temperature drops, the
vehicle level is lower; with an increase in
temperature, the vehicle level rises.
When you unlock the vehicle or open a door,
the vehicle begins to balance the load
discrepancies while still parked. However, for
significant level changes, e.g. after the
vehicle has been stationary for a long period,
the engine must be on. For safety reasons,
the vehicle is only lowered when the doors are
closed. Lowering is interrupted if a door is
opened and continues once the door has
been closed.
G WARNING
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when changing
the vehicle level. You could otherwise trap
yourself or others.
G WARNING
Always select as low a vehicle level as
possible. If the vehicle level is high, the vehicle
center of gravity shifts upwards. This
increases the risk of the vehicle tipping over.
Adapt your driving style to suit the vehicle
level. ESP
® cannot reduce the risk of an
accident if you drive too fast. ESP ® cannot
override the laws of physics.
! When driving on extremely rough terrain,
select a high vehicle level in good time.
Make sure that there is always sufficient
ground clearance to prevent damage to the
vehicle.
! Remove the key from the ignition before
raising one or more wheels with the
appropriate equipment.
For information about driving off-road, see

Y page 174).
