General notes Magic Body Control consists of Active Body
Control (ABC), ROAD SURFACE SCAN as well
as automatic vehicle stabilization in the event
of a crosswind.
Your vehicle automatically adjusts its ride
height to improve driving safety and reduce
fuel consumption. The suspension mode is
adjusted according to your selection (sports
or comfort), the road condition and the
vehicle load. A multifunction camera detects
bumps in the road surface before the vehicle
drives over them. This reduces chassis
movements.

WARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle
or in the immediate vicinity of the wheel
arches when the vehicle is being lowered.
! The vehicle is lowered when the engine is
switched off. When parking, position your
vehicle so that it does not make contact Driving systems

active if you select comfort suspension
tuning. The system is operational at speeds
of up to 81 mph (130 km/h).
This function allows bumps in the road
surface to be detected before the vehicle
drives over them. The spring struts are then
actuated, with the result that chassis
movements are significantly reduced when
driving over bumps.
The system is deactivated when you select
the raised vehicle level or the sports
suspension tuning.
The system may be impaired or may not
function if:
R the road surface is insufficiently lit
R there is poor visibility, e.g. snow, rain, fog
or spray
R there is glare, e.g. from the sun or from
oncoming traffic
R the windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera
R the road surface has no texture or is
reflective, e.g. in the case of newly laid
asphalt, concrete slabs or puddles
R the distance to the vehicle in front is too
short
R sections of the route have a very small
radius of curvature
R you accelerate hard or brake sharply AIRMATIC
General notes AIRMATIC is an air suspension with variable
damping for improved driving comfort. All-
round level control ensures the best possible
suspension and constant ground clearance,
even with a laden vehicle. When you drive
fast, the vehicle is lowered automatically to
improve driving safety and to reduce fuel
consumption. There is also the option to
manually adjust the vehicle level. AIRMATIC consists of level setting, level control and the
Adaptive Damping System ADS.
