General notes AIRMATIC regulates the level of your vehicle.
As well as level control ( Ypage 218), your
vehicle can be equipped with ADS (Adaptive
Damping System) (Y page 217) and ACTIVE
CURVE SYSTEM (Y page 218).
Observe the notes on driving with a trailer
(Y page 264). ADS (Adaptive Damping System) General notes
ADS adapts the damping characteristics to
the current operating and driving situation.
This depends on:
R
your driving style
R the road surface conditions
R the ADS setting
R the vehicle level setting
Your selection remains stored even if you
remove the SmartKey from the ignition lock.

Important safety notes G
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. G
WARNING
The vehicle is lowered if:
R you have selected the Comfort or Sport
suspension tuning and
R lock the vehicle after switching off the
engine
Persons in the vicinity of the wheel arch or the
underbody may thus become trapped. There
is a risk of injury.
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when you switch
off the engine.
! The vehicle is lowered by approximately
10 mm if:
R you have selected the Sport or Comfort
suspension tuning and
R you switch off the engine and then
R lock the vehicle When parking, position your vehicle so that
it does not make contact with the curb as
the vehicle is lowered. Your vehicle could
otherwise be damaged.
Vehicle level Level control adapts the vehicle level
automatically to the current operating and
driving situation. Level control ensures the
best possible suspension and constant
ground clearance, even with a laden vehicle.
This improves driving safety and fuel
consumption.
The AIRMATIC package and ACTIVE CURVE
SYSTEM are always components of AMG
adaptive suspension system (Y
page 217).
Due to the sportier suspension settings
compared to standard vehicles, the levels and
speed thresholds for sinking and raising the
vehicle are different.
In Comfort and Sport driving modes, after
locking the vehicle it lowers to the Sport+
level. When locking the vehicle at the raised
level, the vehicle does not lower.
The settings will remain stored after you
switch off the engine. When starting the
engine, the selected setting, e.g. AMG
adaptive suspension system Comfort, is
restored.
i The vehicle level may change visibly if you
park the vehicle and the outside
temperature changes. If the temperature
drops, the vehicle level lowers; with an
increase in temperature, the vehicle level
rises.
Suspension tuning General notes
The electronically controlled damping system
works continuously. This improves driving
safety and ride comfort. Driving systems
