Driving sys
tems 152 AIRMATIC package*
AIRMATIC enables a suspension tuning set-
ting to be selected and regulates the damping
behaviour and level of your vehicle. The sys-
tem comprises two components: ADS*
(Adaptive Damping System) (Y page 152)
and level control* (Y page 152).
Observe the notes on driving with a trailer in
the "Operation" (Y page 239) section.
ADS* (Adaptive Damping System) ADS adapts the damping characteristics to
the current operating and driving situation.
How this is adjusted depends on:
R your driving style
R the road surface conditions
R the ADS setting
R the vehicle level setting
Your selection remains stored even if you
remove the key from the ignition lock. 1
ADS button
2 SPORT indicator lamp
3 COMF indicator lamp
You can choose between the following ADS
settings:
R AUTO for normal driving situations; indica-
tor lamps 2and 3are off.
R SPORT for sporty driving; indicator lamp
2 is on.
R COMF for a more comfortable ride; indica-
tor lamp 3is on.
X Start the engine.
X Press button 1repeatedly until the
desired setting is selected. Level control* The level control adapts the vehicle level
automatically to the current operating and
driving situation. This results in reduced fuel
consumption and improved handling.
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 may change visibly when you
park the vehicle and the outside temperature
changes. When the temperature drops, the
vehicle level is lower; with an increase in tem-
perature, the vehicle level rises.
When you unlock the vehicle or open a door,
the vehicle begins to balance the load dis-
crepancies while still parked. However, for
significant level changes, e.g. after the vehi-
cle 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. Lowering is interrupted if a door is
opened and continues when the door has
been closed. G

Driving sys
tems 155If a drive wheel spins due to insufficient
grip:
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Accelerate less when driving.
R Adapt your driving style to suit road and
traffic conditions.
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.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake dynamometer.
When doing this, turn the key to position
0 or 1in the ignition. Failure to do this can
cause damage to the drive train or the
brake system.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system. Parktronic*
G
Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It is not a substitute for atten-
tive driving.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. You could otherwise endan-
ger yourself and others. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured.
Parktronic is an electronic parking aid. It indi-
cates visually and audibly the distance
between your vehicle and an object.
Parktronic is activated automatically when
you:
R switch on the ignition
R release the parking brake
R shift the automatic transmission to D,Ror
N
Parktronic is deactivated at speeds above
18 km/h. It is reactivated at lower speeds. Parktronic monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.

Example: sensors in the front bumper,
left-hand side
Range of the sensors The sensors must be free of dirt, ice and
slush, otherwise they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them

Risk of accident
The reversing camera is only an aid and may
display obstacles in a distorted manner,
incorrectly or even not display them at all.
The reversing camera does not relieve you
of the responsibility to pay attention. The
camera cannot show objects:
R that are very close to the rear bumper.
R that are underneath the rear bumper.
R above the tailgate handle.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. This applies to the areas
behind, in front of and next to the vehicle.
You could otherwise endanger yourself and
others. G
Risk of accident
Under the following circumstances, the
reversing camera will not function, or func-
tion in a limited manner:
R if the tailgate 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
white light.
R if the area is lit by fluorescent light (the
display may flicker).
R if there is a sudden change in tempera-
ture, e.g. when driving into a heated
garage in winter. R
if the camera lens is dirty or obstructed.
R if the rear of your vehicle is damaged.
Have the camera position and setting
checked at a qualified specialist work-
shop in this case. Mercedes-Benz recom-
mends that you use a Mercedes-Benz
Service Centre for this purpose.
Do not use the reversing camera in these
types of situation. You could otherwise
injure others or damage objects and your
vehicle while you are parking.
Activating the reversing camera X
Make sure that the key is in position 2in
the ignition lock.
X Engage reverse gear.

fication on/off
The "cooling with dehumidification" function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted. This prevents the windows from misting
up. G
Risk of accident
If the "cooling with air dehumidification"
function is deactivated, the air inside the
vehicle will not be cooled (during warm
weather) or dehumidified. The windows
could mist up more quickly. This may pre-
vent you from observing the traffic condi-
tions, thereby causing an accident. H
Environmental note
The cooling system uses the refrigerant
R134A. This refrigerant does not damage
the earth's ozone layer.
Condensation may drip from the underside of
the vehicle when Thermatic is in cooling
mode. X

In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic air conditioning will achieve
optimal operation if "cooling with air dehu-
midification" is also activated. If necessary,
cooling with air dehumidification can be deac-
tivated. Cont

G
Risk of injury
Very hot or very cold air can flow from the
air vents. This could cause burns or frost-
bite to bare skin in the immediate vicinity
of the vents. Keep bare skin away from
these air outlets. If necessary, direct the
airflow away to a different area of the vehi-
cle interior.
Please observe the following notes to ensure
that the air can flow freely through the air
vents:
R keep the air inlet between the windscreen
and the bonnet free of deposits, such as ice
and snow, to guarantee the supply of fresh
air into the vehicle interior.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior.
i Position the sliders for the centre air
vents in the central position to provide vir-
tually draught-free ventilation. Cont
