Description
App lies to vehicles: with Adapt ive Air Suspension
Air suspension and damping con be adjusted
separately.
Adaptive Air Suspension is an electronically
controlled springing and damping system .
This chassis system makes it easier on the
driver by adapt ing to the particular situation
through imperceptible control processes.
The Adaptive Air Suspension component reg -
ulates ground clearance depending on vehicle
speed and driver input. It functions independ-
ently from the load condition . Accelerating to
a speed above a predetermined
limit will
make the vehicle lower itself . On the other
hand, driving more slowly results in the vehi-
cle raising again at specific speeds.
The damping component provides individual
control of the damping forces . For example,
w ith damping characterist ics set to provide
greater comfort, damping is set somewhat
harder for a br ief per iod only as required, for
example, when go ing aro und a curve or when
braking.
Settings
Adapt ive Air Suspension prov ides the driver
with the opportun ity to set the chassis charac-
ter istics also to their individual preference.
With the driving modes Comfort, Automatic
and Dynamic the driver has three chassis set-
tings available, ranging from comfort to spor-
ty. The Offrood mode can be selected for driv-
ing on poor quality stretches of road. In addi-
tion, Lift provides a fifth mode, which can be
selected when exceptionally high ground
clearance is needed

The height of the parked vehicle can
change due to temperature
fluctuations or
changes in load .

Note
- Whenever you park your vehicle, a lways
make sure there is adequate clearance
above and below the vehicle. The he ight
of the parked vehicle can change as the
result of temperature
fluctuations,
changes in load condition and changes in
the driving mode (ground clearance).
- If the vehicle is be ing t ransported (e.g .
by tow truck, train, sh ip, etc.), mount the
tie-down chains/cables over the running
surface (circumference) of the tires. Nev-
er secure the vehicle by the axle, the sus -
pension struts or the front or rear tow-
line eye . For technica l reasons, the pres-
sure in the suspens ion struts may change
dur ing the transport, which could result
in the vehicle no longer being secured
properly.
- If you are going to tow a trailer with a
trailer hitch that was not installed ac-
cording to factory specif ications, you
must activate the tra ile r operation mode

Tips
- Before you can raise your vehicle using
the vehicle jack (for example, when
chang ing a f lat tire) or a veh icle lift, you
must activate the jacking mode

page 161.
- On some mode ls, the vehicle can reach
its maximum speed only in the Automat -
ic and Dynamic modes.
Chassis controls
Appli es to vehicles : wit h Adaptive Air Suspension
Five different driving modes can be set by the
driver.
The automatic control processes are speed-
and time-dependent.
