AIRMATIC
General notes
AIRMATIC is an air suspension with variable
damping for improved driving comfort. All-round
level control ensures the best possible suspen-
sion 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 PLUS.
Important safety notes

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.

Suspension tuning
General notes
The Adaptive Damping System ADS PLUS auto-
matically controls the calibration of the damp-
ers.
The damping is tuned individually to each wheel
and depends on:
R
your driving style, e.g. sporty
R
the road surface condition, e.g. bumps
R
your individual selection, i.e. sports or com-
fort
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
i
You can choose between the sporty and
comfortable mode. One of the two modes is
always active.
