AIRMATIC package
General notes AIRMATIC is an air suspension system with var-
iable damping for improved driving comfort.
Level control ensures the best possible suspen-
sion and constant ground clearance, even with a
laden vehicle. When you drive fast, the vehicle is
lowered automatically to improve driving safety
and to reduce fuel consumption. There is also
the option to manually adjust the vehicle level.
AIRMATIC consists of: R
level settings R
level control and R
ADS or ADS PLUS (Adaptive Damping Sys-
tem)
All vehicles (except Mercedes-AMG vehi-
cles): your vehicle may also be equipped with
the ACTIVE CURVE SYSTEM ( Y
page 189).
Mercedes-AMG vehicles: your vehicle is equip-
ped with the ACTIVE CURVE SYSTEM
( Y
page 189).
Observe the notes on driving with a trailer
( Y
page 225).
The vehicle level can be set using the DYNAMIC
SELECT controller ( Y
page 147) or the level but-
ton ( Y
page 190). The setting always corre-
sponds to the last selected function. 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.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load discrep-
ancies while still parked. However, for signifi-
cant level changes, such as after the vehicle has
been stationary for a long period, the engine
must be on. For safety reasons, the vehicle is
only lowered when the doors are closed. Low-
ering is interrupted if a door is opened, and it
continues once the door has been closed.
ADS and ADS PLUS (Adaptive Damping
System)
General notes The Adaptive Damping System automatically
controls the calibration of the dampers. The
damping characteristics adapt to the current
operating and driving situation.
The damping is tuned individually to each wheel
and depends on: R
your driving style, e.g. sporty R
the road surface conditions R
the drive program selected R
the vehicle level setting

Driving systems
Driving and parking

In the Comfort drive program, the driving char-
acteristics of your vehicle are more comforta-
ble. Therefore, select this mode if you favor a
more comfortable driving style. Also select the
Comfort drive program when driving fast on
straight roads, e.g. on straight stretches of high-
way. X
Select the Comfort drive program using
DYNAMIC SELECT controller C .
The vehicle is adjusted to normal level
All vehicles (except Mercedes-AMG vehi-
cles): in the Comfort drive program, the vehicle
is: R
lowered by 0.6 in (15 mm) if you drive at
speeds above 78 mph (125 km/h) R
raised again if you drive at speeds below
50 mph (80 km/h)
Mercedes-AMG vehicles: in the Comfort drive
program, the vehicle is: R
lowered by 0.4 in (10 mm) if you drive at
speeds above 112 mph (180 km/h) R
raised again if you drive at speeds below
87 mph (140 km/h)
Selecting Sport mode
The firmer setting of the suspension tuning in
the Sport drive program ensures even better
contact with the road. Select this drive program
when employing a sporty driving style, e.g. on
winding country roads.
DSR is not available in the Sport drive program.

All vehicles (except Mercedes-AMG vehi-
cles): the vehicle is lowered by 0.6 in (15 mm)
compared to the normal level. Mercedes-AMG vehicles: the vehicle
remains at the normal level.
Selecting Sport Plus tuning (Mercedes-
AMG vehicles)
The very firm setting of the suspension setting in
the Sport Plus drive program ensures the best
possible contact with the road. Select this drive
program when employing a sporty driving style,
e.g. on winding country roads or primarily when
driving on race circuits.
DSR is not available in the Sport Plus drive pro-
gram. For further information on DSR, see

ACTIVE CURVE SYSTEM The ACTIVE CURVE SYSTEM uses active stabil-
izers to optimize both driving comfort and vehi-
cle dynamics. Depending on the drive program
selected ( Y
page 151), the ACTIVE CURVE SYS-
TEM also changes the setting.
If you have selected the Comfort drive program:R
rolling movement is reduced in the event of
changing surface undulations R
the roll angle when cornering is reduced R
the driving is dynamic
If you have selected the Sport drive program:R
the roll angle is reduced significantly R

Range of the sensors General notes Parking Assist PARKTRONIC does not take into
account obstacles located: R
below the detection range, such as persons,
animals or objects R
above the detection range, such as overhang-
ing loads, truck overhangs or loading ramps

Sensors in the front bumper, left-hand side
(example)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean
the sensors regularly, taking care not to scratch
or damage them ( Y

Parking tips: R
On narrow roads, drive as close to the parking
space as possible. R
Parking spaces that are littered or overgrown
might be identified or measured incorrectly. R
Parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly. R
Snowfall or heavy rain may lead to a parking
space being measured inaccurately. R
Pay attention to the warning messages of
Parking Assist PARKTRONIC during the park-
ing procedure ( Y
page 192).R
You can intervene to correct the steering pro-
cedure at any time. Parking Pilot will then be
canceled. R
When transporting a load that protrudes from
your vehicle, you must not use Parking Pilot. R
Never use Parking Pilot when snow chains are
mounted. R
Make sure that the tire pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle.
Use Parking Pilot for parking spaces that are: R
parallel or at right angles to the direction of
travel R
on straight roads, not bends R
on the same level as the road, e.g. not on the
pavement
Detecting parking spaces Objects located above the detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking/exiting procedure is
calculated, e.g. overhanging loads, tail sections
or loading ramps of trucks. Parking Pilot may
therefore guide you into the parking space too
early.
G WARNING
If there are objects above the detection range: R
Parking Pilot may steer in too early R
the vehicle may not stop in front of these
objects
You may cause a collision as a result. There is
a risk of an accident.
If objects are located above the detection
range, stop and deactivate Parking Pilot. Further information about the detection range
( Y
page 193).
Parking Pilot does not assist you parking in
spaces at a right angle to the direction of travel
if: R
two parking spaces are located directly next
to one another R
the parking space is directly next to a low
obstacle such as a low curb R
you park forwards
Parking Pilot does not assist you parking in
spaces parallel with or at a right angle to the
direction of travel if: R
the parking space is on a curb R
the system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks R
the area is too small for the vehicle to maneu-
ver into R
the parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer
