Adaptive Air Suspension
Air suspension and damping
Description
App lies to vehicles: with Adapt ive Air S uspe nsio n
Air suspension and damping con be adjusted
separately.
Adaptive A ir 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.
W ith 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
c::;, page 157, Chassis con
trols .
The modes are set in MMI <::;,page 159.

A WARNING
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, ship, etc.), mount the
tie-down chains/cables over the running
surface (circumference) o f 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 traile r operation mode
man ually
<::;,page 161.
(D Tips
-Before you can raise your vehicle using
the vehicle jack (for example, when
chang ing a flat tire) or a vehicle lift, yo u
must activate the jacking mode
c::;, page 161.
-On some models, the vehicle can reach
its maximum speed only in the
Automat
ic
and Dynamic modes.
Chassis controls

Five different driving modes can be set by the
driver.
T he automatic control processes are speed
and time-dependent. For example, it is not

Displaying the vehicle level
The current vehicle leve l is shown with seg
ments fi lled out in the segment disp lay @. If
on ly the bottom segment is filled out, the ve
hicle is at highway leve l. If all segments are
fi lled out, the vehicle is at high level 2 and has
the greatest amount of ground clearance pos
sible.
While the vehicle is being raised or lowered,
the target level is indicated by an arrow @
¢
fig. 191 or a white border @¢ fig. 192. The
arrow/border disappears aga in when the vehi
cle is at the target level.
Jacking mode when changing a flat tire
Applies to vehicles: with Adaptive Air Suspension
This mode must be activated in the MMI be
fore raising the vehicle with a jack or on a ve
hicle lift.
.,. Select: ICARI funct ion button> ! SETUP I func
t ion button >
Jacking mode. Or
.,. Select:
I CARI funct ion button > Car systems*
control button > Servicing & checks > Air
susp.: tire change .
The vehicle jack mode must be activated be
fore changing a wheel so that the automatic
control processes fo r the a ir suspension do
not make lift ing with the vehicle jack more dif
ficult.
The check lamp
II i n the instrument cluster
d isp lay illuminates in vehicle jack mode.
0) Tips
The vehicle jack mode is switched off auto
mat ically at speeds above 9 mph (15 km/
h).
Towing a trailer
Appl ies to vehicles: with towing hitch and Adaptive Air
Suspension
Automatic lowering is not desirable when
towing a trailer.
.,. Se lect: ICAR I function button> !SETUP I func
tion button >
Towing mode . Or
Adaptive A ir Suspension 161
.,. Select: !CAR I function button > Car systems*
contro l button > Vehicle settings > Air
susp.: towing .
As long as towing mode is activated, a vehicle
with a trai ler appears in the
adaptive air sus
pension
main menu.
Level Adjustment when towing a trailer
- Before hitching up the trailer and before ad
jus ting the tongue weight at the trailer, the
automatic or comfort mode
must be select
ed so that the ve hicle can be at normal level
¢ page 159, MMI settings.
-If driving in dynamic mode is desired, this
mode
must be selected before hitching up
the trailer and before adjusting the tongue
weight. However, note that your vehicle is lowered and ground clearance is reduced.
- If you have to dr ive under difficult road con
ditions, you can select offroad or lift mode,
after hitch ing up the trailer or after adjust
ing the tongue weight.
- If the veh icle is at
normal level, and you se
lect offroad mode wh ile traveling at speeds
higher than 22 mph (35 km/h), the veh icle
w ill not be ra ised. Offroad mode will appear
as the active mode in the MMI Display.
- If the veh icle is in offroad mode at
high level
1 ,
it automatically lowers to normal level
when the ve hicl e is t ravel ing at speeds ex
ceeding approximately 31 mph (SO km/h).
The vehicle is automatically raised to
high
level 1
again when the traveling speed falls
be low approximately 25 mph (40 km/h).
Restrictions when operating with a trailer
When operating w ith a tra iler, the lift mode
can only be selected up to about 12 mph (20
km/h). Lift mode is automatically cance led
again when a speed of about 25 mph (40 km/
h) is exceeded.
If the vehicle is in automatic, comfort, offroad
or lift mode before the trai ler towing mode is
activated, the dynamic mode cannot be acti
vated.
If the vehicle is in dynamic mode before tow-
ing operation is activated, it can be driven in
