Rapidly continue to depress the brake until
HOLD :appears in the instrument cluster.
HOLD is activated. You can release the
brake pedal.
i You cannot activate HOLD when Distronic
Plus* is activated.
i The brake pedal does not return com-
pletely to the rest position while HOLD is
activated.
i If HOLD is not activated when you
depress the brake pedal, wait for a short
time and then try again. G
Risk of accident
The vehicle's brakes are applied when HOLD
is activated. For this reason, deactivate HOLD
if the vehicle is to be set in motion by other
means (e.g. in a car wash or by towing).
Deactivating HOLD HOLD is deactivated if:
R
you depress the accelerator pedal with the
transmission in position Dor R.
R you shift the automatic transmission to P.
R you release the brakes fully and apply them
again with a certain amount of pressure
until HOLD goes out in the instrument clus-
ter.
R you secure the vehicle using the electric
parking brake.
R you activate Distronic Plus*.
i After a time, the electric parking brake
secures the vehicle and relieves the service
brake. G
Risk of accident
Never get out of the vehicle when HOLD is
activated.
HOLD must never be operated or deactivated
by a passenger or from outside the vehicle. HOLD does not replace the electric parking
brake and must not be used for parking.
The HOLD braking effect is cancelled and the
vehicle can start moving if:
R HOLD is deactivated by depressing the
accelerator pedal or the brake pedal.
R there is a malfunction in the system or an
interruption in the power supply, e.g. bat-
tery failure.
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
R the battery is disconnected. G
Risk of accident
If you wish to leave the vehicle or park it,
deactivate HOLD and secure the vehicle
against rolling away. AIRMATIC*
Vehicle level Your vehicle automatically adjusts its ride
height to reduce petrol consumption and
improve driving safety.
The "Normal" and "Raised" vehicle levels can
be set.
Depending on the vehicle height that has
been set, the vehicle automatically adjusts its
height dependent on the current speed. The
vehicle is lowered by up to 10 mm as the
speed increases. As the speed is reduced, the
vehicle is raised up to the set vehicle height.
Setting the vehicle level manually
Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces.
G
Risk of injury
Make sure that nobody is in the vicinity of the
wheel housing or under the vehicle while low-
ering the vehicle when it is stationary. Other-
wise, limbs could become trapped. 246

vehicle speeds above 120 km/h or if the
speed has been between 80 km/h and
120 km/h for more than approximately
three minutes. If you do not drive within this
speed range, the raised level remains
stored, even when the key is removed from
the ignition lock.
Suspension tuning The Adaptive Damping System (ADS) auto-
matically controls the calibration of the
dampers and springs. The damping is tuned individually 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. sports or com-
fort
Your selection remains stored even if you
remove the key from the ignition lock. Sports tuning
The firmer suspension tuning in sports mode
ensures even better contact with the road.
Select this mode when employing a sporty
driving style, e. g. on winding country roads.

Risk of injury
The vehicle is lowered when the engine is
switched off. Therefore, make sure that
nobody is in the vicinity of the wheel housing
or under the vehicle when you switch off the
engine. Otherwise, limbs could become trap-
ped.
! The vehicle is lowered by about 5 mm
when the engine is switched off. When
parking, make sure that you stop your vehi-
cle so that it does not make contact with
the kerb as it is lowered. Otherwise, the
vehicle could be damaged.

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. G
Risk of accident
4MATIC cannot reduce the risk of an accident
if you drive too fast.
If 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. PARKTRONIC
G
Risk of accident
PARKTRONIC is only an aid and may not
detect all obstacles. It does not relieve you of
the responsibility of paying attention.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
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 with
ultrasound. It assists you when parking by
displaying the distance between your vehicle
and an obstacle. It also emits a warning tone
when you approach an obstacle.
PARKTRONIC is activated automatically when
you switch on the ignition, release the electric
parking brake or start the engine and shift the
automatic transmission to D,Ror N. Driving systems

PARKTRONIC is deactivated at speeds above
18 km/h. PARKTRONIC is reactivated at
lower speeds. PARKTRONIC is deactivated
when you shift the automatic transmission to
P or engage the electric parking brake and
switch off the engine.
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. Side view Top view

When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. PARK-
TRONIC does not detect such objects when
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brake
system or a pneumatic drill could cause
PARKTRONIC to malfunction.
Minimum distance Centre Approximately 20 cm

You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. Further information
can be found in the index under "Radar
sensor system".
Vehicles with COMAND and navigation sys-
tem*: the radar sensor system is automati-
cally deactivated near radio telescope facili-
ties (Y page 411).
If you want Park Assist to assist you, the radar
sensor system must be activated and opera-
tional.
Park Assist is an electronic parking aid with
radar sensors. It assists you when parking by
displaying the distance between your vehicle
and an obstacle, and by emitting a warning
tone when you approach an obstacle.
Park Assist is automatically activated when
you shift the automatic transmission to D,R
or Nwhile the engine is running.
Park Assist is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
Park Assist is also deactivated when you shift
the automatic transmission to Por switch off
the engine.
Park Assist is deactivated when the transmis-
sion is in position Nif you use the electric
parking brake to secure the vehicle.
Park Assist monitors the area around your
vehicle using four sensors in the front bumper
and two sensors in the rear bumper.

Collision warning Park Assist detects obstacles from some dis-
tance. If you reverse towards an obstacle you
will hear a warning tone. You must brake to
avoid a collision. The collision warning tone
does not sound if you are very close to the
obstacle. Instead, you will hear the corre-
sponding warning tone for the rear area warn-
ing indicator.
