When dr iving with a trailer, the electrical con-
nection to the trailer has been correctly estab-
lished.
= If a loss of tyre pressure or a defective tyre is
detected and displayed.
If you deactivate the Active Lane Keeping Assist
warning and the lane markings cannot be clearly
detected, it is possible that no lane-correcting
brake application takes place (  page 268).
The system may be impaired or may not function
particularly in the following situations:
= If there is poor visibility, e.g. due to insuPcient
illumination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray.
= If there is glare, e.g. from oncoming traPc, the
sun or reOections.
= If there is dirt on the windscreen in the vicinity
of the multifunction camera or if the camera is
misted up, damaged or obscured.
= If there are no lane markings, or several
unclear lane markings are present for one
lane, e.g. around roadworks. =
If t he lane markings are worn, dark or cov-
ered.
= If the distance to the vehicle in front is too
short and thus the lane markings cannot be
detected.
= If the lane markings change quickly, e.g. lanes
branch oM, cross one another or merge.
= If the carriageway is very narrow and winding.
= Vehicles with Driving Assistance Package: if
the radar sensors in the rear bumper are dirty
or covered in snow and an obstacle is detec-
ted in your lane, no lane-correcting brake
application takes place.

the best possible suspension and constant ground
clear ance, even with a laden vehicle. When driving
at speed, the vehicle is lowered automatically to
improve driving safety and to reduce fuel con-
sumption. You also have the option of manually
adjusting the vehicle level.
AIRMATIC is comprised of the following functions
and components:
= All-round air suspension
= Speed-dependent lowering
= Manually selectable high level setting for
greater ground clearance which can be adjus-
ted using a level button

= Sport +: approx. -25 mm
If the entry/exit level function is activated, the
vehicle is lowered to the Sport + level to facilitate
entering/exiting the vehicle. When driving at
speeds of approximately 30 km/h or above, the
entry/exit level is deactivated and the vehicle is
raised (  page 272). Operation with a trailer or bicycle rack
If tr
ansport equipment, for example a trailer or
bicycle rack, is attached to the trailer hitch and
the electrical connection has been correctly
established:
= In drive program F and G, the vehicle
adopts the normal level starting from a speed
of 30 km/h.
= In all other drive programs, the vehicle
remains at normal level irrespective of speed.

AIRMATIC may not be available or have only limi-
ted availability in the following cases:

&
WARNING Risk of accident because v ehi-
cle level is too high
Driving characteristics may be impaired.
The v
ehicle can dris outwards, for example,
when steering or cornering. 
Choose a vehicle level which is suited to
t

he driving style and the road surface
conditions. &
WARNING Risk of entr
apment from vehi-
cle lowering
When lowering the vehicle, other people could
become tr
apped if their limbs are between the
vehicle body and the tyres or underneath the
vehicle. 
Make sure no one is underneath the
v

ehicle or in the immediate vicinity of the
wheel arches when the vehicle is being
lowered. &
WARNING Risk of becoming tr
apped due
to the vehicle lowering
Vehicles with AIRMATIC or level control: when
y
ou unload luggage or leave the vehicle, the
vehicle Nrst rises slightly and then returns to
the set level shortly aserwards.
You or anyone else in the vicinity of the wheel
arches or the underbody could thus become
trapped.
The vehicle can also be lowered aser being
locked. 
When leaving the vehicle, make sure that
nobody is in t
he vicinity of the wheel
arches or the underbody. *
NOTE Damag
e due to vehicle lowering Parts of the body could be damaged when the
v
ehicle is lowered. 
Make sure that there are no obstacles
suc
h as kerbs underneath or in the
immediate vicinity of the body when the
vehicle is being lowered. *

Y
ou could otherwise fail to recognise
dangers. E-ACTIVE BODY CONTROL is an electrohydraulic
suspension sy

stem with variable damping for
improved driving comfort. The all-round level con-
trol system ensures the best possible suspension
and constant ground clearance, even with a laden
vehicle. When driving at speed, the vehicle is low-
ered automatically to improve driving safety and
to reduce fuel consumption. The suspension set-
ting is adjusted depending on the road surface,
vehicle load and the drive program selected.
The ROAD SURFACE SCAN function detects areas
of unevenness in the road before you drive over
them by means of a multifunction camera. This
reduces chassis movements. The damping is adjusted individually to each
wheel and depends on t
he following factors:
= Driving style, e.g. sporty
= Road condition, e.g. bumps
= Drive program
E-ACTIVE BODY CONTROL is comprised of the fol-
lowing functions and components:
= Vehicles with Driving Assistance Package:
ROAD SURFACE SCAN
= Curve inclination function CURVE
= Recovery mode
= Individual wheel control
= Air suspension with automatic level control
= Speed-dependent lowering to reduce fuel con-
sumption

System limits
ROAD SURFACE SCAN can be impaired in the fol-
lowing situations or can stop functioning:
= If the carriageway is insuPciently lit, e.g. at
night.
= In snow, rain, fog, heavy spray, if there is glare,
in direct sunlight or in greatly varying light
conditions.
= If the windscreen in the area of multifunction
camera is dirty, misted up, damaged or cov-
ered.
= If the road surface has no optic structure or
reOects light.
= If you are driving too close to the vehicle in
front. =
If sections of t he route have a very small
radius of curvature.
= During abrupt driving manoeuvres, e.g. heavy
braking or sudden acceleration.
Observe the notes on cleaning the multifunction
camera ( page 378).
Function of recovery mode &
WARNING Risk of injur
y due to the vehicle
moving up and down
During recovery mode, the vehicle moves up
and do
wn and can cause injuries. 
When activating recovery mode, make
cer

tain that no one is in the vicinity of
the vehicle. *
NOTE Risk of damag
e due to the vehicle
moving up and down When free driving mode is activated, the vehi-
cle mo

ves up and down. Vehicle parts may be
damaged if the underbody bottoms out. 
Make sure that there is suPcient g
round
clearance when rocking free mode is
activated. Recovery mode is a function of the suspension
whic

h can assist the driver on loose surfaces (e.g.
sand, snow) when freeing a vehicle which has
become stuck.
The vehicle body rocks in slow, vertical motions
when recovery mode has been activated. This
temporarily puts the wheels under greater load,
which means they have increased traction and the
vehicle is freed.
You can activate free driving mode via OM-road
Assist ( page 281).
Function of individual wheel control &
WARNING Risk of becoming tr
apped due
to the vehicle lowering
The vehicle can be lowered when the individ-
ual wheel contr
ol function has been activated.
Body parts could become trapped if they are
between the vehicle body and the tyres or
underneath the vehicle. Driving and parking
