General notes AIRMATIC enables
asuspension tuning set-
ting to be selected and regulates the damping
behaviou rand level of your vehicle. The sys-
tem comprises aminimum of two compo-
nents. These are ADS (Adaptive Damping Sys-
tem) (Y page 188 )and level control
(Y page 189) .Your vehicle ma yalso be equip-
ped with the Active Curv eSystem
(Y page 188).
Observe the notes on driving with atrailer
(Y page 226).
ADS (Adaptive Damping System) General notes
ADS adapts th

R the road surface conditions
R the AD Ssetting

Sports tuning
The firmer suspension tunin ginSport mode
ensures even better contact with the road.
Select this mode when employing asporty
drivin gstyle, e.g. on winding country roads.
X Press button :.
Indicator lamp ;lights up. You have selec-
ted "Sports tuning". The vehicle is lowered
by 15 mm.
Comfort tuning
In comfort mode, the driving characteristics
of your vehicle are more comfortable. Select
this mode if you prefer amore com fortable
driving style ,but also when drivin gfast on
straight roads, e.g. motorways.
X Press button :.
Indicator lamp =lights up. You have selec-
ted "Comfort tuning". The vehicle is raised
by 15 mm.
Active Curve System The Active Curve System uses activ
estabil-
isers to optimis eboth drivin gcomfort and
vehicle agility. Depending on the AD Smode 188
Driving systemsDriving and parking

selected (Y
page 188), the Ac tiveCurve Sys-
tem also changes the setting.
If you select ADS comfort mode:
R rolling movement is reduced in the event of
changing surface undulations.
R the roll angle when cornering is reduced.
R the driving style is agile.
If you select ADS sport mode:
R the roll angle is reduced significantly.
R the driving style is even more agile.
Leve lcontrol Import
ants afety notes
Leve lcontrol adapts the vehicle leve lauto-
matically to the current operating and driving
situation. This results in reduced fuel con-
sumption and improved handling.
If you select ADS comfort mode
(Y page 188), the vehicle is lowered to high-
spee dlevel as the speed increases. As the
vehicle decelerates, the vehicle is raised back
up to highway level.
If you select ADS sport mode (Y page 188),
the vehicle skips highway level and lowers
directly to high-speed level dependin gonthe
basic setting (Y page 189).
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle
to adjust to the new level as quickly as pos-
sible.
The vehicle level ma ychange visibly if you
par kthe vehicle and the outside temperature
changes. If the temperature drops, the vehi-
cle level lowers; with an increase in temper-
ature, the vehicle level rises.
If you unlock the vehicle or open adoor, the
vehicle begins to compensat efor load dis-
crepancies while still parked. However, for
significant leve lchanges, e.g. after the vehi-
cle has been stationary for along period, the
engin emust be on. For safety reasons, the
vehicle is only lowered when the doors are
closed .Lowering is interrupted if adoor is opened; it con
tinues once the doo rhas been
closed. G
WARNING
Make sure that nobody is near the wheel arch
or vehicle underside when you make achange
to the vehicle level. Otherwise, you or others
ma ybet rapped. G
WARNING
Always select as lo wavehicle level as possi-
ble. If the vehicle level is high, the vehicle
centre of gravity shifts upwards. This increa-
ses the risk of the vehicle tipping over.
Adapt your driving style to suit the vehicle
level. ESP ®
cannot reduc ethe risk of an acci-
dent if you drive too fast. ESP ®
cannot over-
rid ethe laws of physics.
! When driving on extremel yrough terrain,
select ahigh vehicle level in good time.
Make sure there is always sufficient ground
clearance to prevent damage to the vehi-
cle.
For information abou tdriving off-roa d, see
( Y page 166).
Basic settings
The exten ttowhich the vehicle is rai sedor
lowered depends on the basic setting selec-
ted. Select raised level for off-road driving or
highway/high-spee dlevel for normal roads.
The indiv idua lvehicle levels differ from high-
way level as follows:
R Highway level: +/ –0mm
R High-speed level: –15 mm
R Raised level: +60 mm
Raise dlevel
Only select raise dlevel if this is appropriate
for the road conditions. Otherwise, fuel con-
sumption may increase and handling may be
affected. Driving systems
