Suspension setting
The electro-hydraulically controlled ABC sus- pension system works continuously. This
improves driving safety and comfort. The sys- tem detects the vehicle level and the vehicle
load and adjusts the setting accordingly. You
can also choose between a particularly sporty
(SPORT), a comfortable (COMFORT) as well as a comfortable mode with cornering func-
tion (CURVE).
The ABC suspension system is tuned individ-
ually to each wheel and depends on:
R your driving style, e.g. sporty
R the road surface condition, e.g. bumps
R your individual selection, i.e. sporty or com-
fort or comfort with the CURVE dynamic
cornering function
R the vehicle load
R the force of the side wind
Your selection remains stored even if you
remove the key from the ignition lock. The firmer suspension setting in SPORT mode
ensures even better contact with the road.
The steering response behaviour is sporty.
Select this mode on winding country roads or
motorways, for example.

ROAD SURFACE SCAN i
This function is not available in all coun-
tries. The ROAD SURFACE SCAN function monitors
the road in front of the vehicle using a multi-
function camera :at the top of the wind-
screen. This function is automatically active if
you select comfort suspension tuning. The
system is operational at speeds of up to
130 km/h.
This function allows bumps in the road sur-
face to be detected before the vehicle drives over them. The spring struts are then actu-
ated, with the result that chassis movements
are significantly reduced when driving over
bumps.
The system is deactivated when you select
the raised vehicle level, sports mode or the
dynamic cornering function.
The system may be impaired or may not func-
tion if:
R the road surface is insufficiently lit
R there is poor visibility, e.g. snow, rain, fog or
spray 206
Driving systemsDriving and parking

R
there is glare, e.g. from the sun or from
oncoming traffic
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity of the camera
R the road surface has no texture or is reflec-
tive, e.g. in the case of newly laid asphalt,
concrete slabs or puddles
R the distance to the vehicle in front is too
short
R sections of the route have a very small
radius of curvature
R you accelerate hard or brake sharply AIRMATIC
General notes AIRMATIC is an air suspension system with
variable damping for improved driving com-
fort. All-round level control ensures the best
possible suspension and constant ground
clearance, even with a laden vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption. There is also the
option to manually adjust the vehicle level.
AIRMATIC consists of level setting, level con-
trol and the Adaptive Damping System ADS
PLUS.
Important safety notes G
WARNING
People's limbs may become trapped if they
are located underneath the vehicle or
between the vehicle body and the tyres when the vehicle is lowering. There is a danger of
injury.
When lowering the vehicle, make sure no one
is underneath the vehicle or in the immediate vicinity of the wheel arches. Vehicle level Setting the raised vehicle level
It is possible to choose between the "Normal"
and "Raised" vehicle levels. Select the "Nor-
mal" setting for normal road surfaces and

Load compensation
The vehicle can compensate differences in
the vehicle level by raising or lowering the
axles. 4MATIC (permanent all-wheel drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
, it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic con- ditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in the lane.
If a drive wheel spins due to insufficient grip:
R when pulling away, only depress the accel-
erator pedal as far as is necessary.
R accelerate less when driving
! Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz implied warranty. All
wheels must remain either on the ground or
be fully raised. Observe the instructions for towing the vehicle with all wheels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres),with snow
chains if necessary. PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a substi-
tute for your attention to the immediate sur-
roundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals
or objects in range while manoeuvring and
parking.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and
objects which absorb ultrasonic sources.
Ultrasonic sources, such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill, could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on uneven terrain.
PARKTRONIC is activated automatically if
you:
R switch on the ignition
R shift the transmission to position D,Ror N
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
Range of the sensors General notes
PARKTRONIC does not take into account
obstacles located:
R below the detection range, e.g. persons,
animals or objects
R above the detection range, e.g. overhang-
ing loads, tail sections or loading ramps of
goods vehicles Driving systems

X If problems persist, have PARKTRONIC checked at a qualified
specialist workshop. Only the red segments
in the PARKTRONIC
warning displays are lit.
PARKTRONIC is then
deactivated. The PARKTRONIC sensors are dirty or there is interference.
X Clean the PARKTRONIC sensors (Y page 347).
X Switch the ignition back on. The problem may be caused by an external source of radio or
ultrasound waves.
X See if PARKTRONIC functions in a different location. Active Parking Assist
General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention and brake application
can assist you during parking and when exit-
ing a parking space. You may also use
PARKTRONIC (Y page 209).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or
objects are in the manoeuvring range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tyres.
Active Parking Assist may also display spaces not suitable for parking, e.g.:
R parking or stopping prohibitions
R in front of driveways or entrances and exits
R unsuitable surfaces 212
Driving systemsDriving and parking

:
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Active Parking Assist is activated automati-
cally when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde- pendently locates and measures parking
spaces on both sides of the vehicle.
Active Parking Assist will only detect parkingspaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel
and are at least 1.5 m wide
R that are parallel to the direction of travel
and at least 1.0 mlonger than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 m wider than your
vehicle
i Note that Active Parking Assist cannot
measure the size of a parking space if it is at
right angles to the direction of travel. You
will need to judge whether your vehicle will
fit in the parking space.
When driving at speeds below 30 km/h, you
will see parking symbol ;as a status indi-
cator in the instrument cluster. When a park- ing space has been detected, an arrow
towards the right or the left also appears.
Active Parking Assist only displays parking
spaces on the front-passenger side as stand-
ard. Parking spaces on the driver's side are
displayed as soon as the turn signal on the driver's side is activated. When parking on the
driver's side, this must remain switched on
until you acknowledge the use of Active Park- ing Assist by pressing the abutton on the
multifunction steering wheel. The system
automatically determines whether the park-
ing space is parallel or at right angles to the
direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 15 m away from it.

General notes Reversing camera
:is under a flap in the
boot lid.
Reversing camera :is an optical parking
and manoeuvring aid. It shows the area
behind your vehicle with guide lines in the
COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
i The text of messages shown in the
COMAND display depends on the language setting. The following are examples of
reversing camera messages in the
COMAND display.
Important safety notes The reversing camera is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals
or objects in range while manoeuvring and
parking. Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R if the boot lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if the camera lens mists up, e.g. when driv-
ing into a heated garage in winter, causing
a rapid change in temperature
R if the camera lens is dirty or obstructed.
Observe the notes on cleaning
(Y page 347)
R if the rear of your vehicle is damaged. In this
case, have the camera position and setting checked at a qualified specialist workshop
The field of vision and other functions of the
reversing camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. licence plate holder, bicycle rack).
The guide lines in the COMAND display show
the distances to your vehicle. The distances
only apply to road level.
i The reversing camera is protected from
raindrops and dust by means of a flap.
When the reversing camera is activated,
this flap opens.
The flap closes again when:
R you have finished the manoeuvring proc-
ess
