AIRMATIC package
General notes
AIRMATIC enables a suspension tuning
setting to be selected and regulates the
damping behavior and level of your vehicle.
The system comprises two components: ADS
(Adaptive Damping System) (
Y page 184)
and level control ( Y page 181) .
Observe the notes on driving with a trailer
(
Y page 198).
AMG vehicles
The AIRMATIC package is part of the standard
equipment. Due to the sportier suspension
tuning when compared to standard vehicles,
the level positions in the ADS settings and the
speed thresholds for raising and lowering the
vehicle are different.
The vehicle is lowered from highway/high-
speed level to
ADS Sport level around 20
seconds after locking. The vehicle is not
lowered from raised level after locking. When
the engine is started, the previous setting,
e.g.
ADS COMF, is restored.
! Always keep in mind the differences in
ground clearance and vehicle height when
compared to standard vehicles. You could
otherwise damage the vehicle.
You will find different values for ground
clearance and vehicle height with regard to:
