Performance enhancement system
Airbrake
The Airbrake enhances the vehicle’s driv-
ing stability. It adapts the aerodynamics of
the vehicle to the driving conditions ac-
cording to the speed and the mode set.
This is achieved using a moveable spoiler.
The Airbrake is located at the rear edge of
the trunk lid.Warning!
G
When operating the Airbrake, make sure
there is no danger of anyone being harmed
by the Airbrake operation (i.e. raising and
lowering of flap). Be especially careful when
small children are around.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The Airbrake cannot reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
iIf the ESP is active, the Airbrake is
automatically deactivated.iIn winter operation, the maximum ef-
fectiveness of the Airbrake is only
achieved with winter tires (M + S tires)
or snow chains as required.

If you need to brake in an emergency from
a speed of more than 60 mph (95 km/h),
the Airbrake automatically swings upwards
to an angle of 62°.
This allows you to achieve the best possi-
ble braking performance in an emergency.

Hard braking activates the Airbrake which
may block the view through the interior rear
view mirror. In this case, monitor the traffic
behind you through the exterior rear view
mirrors.
