is armed on a locked vehicle, you will receive a
notiNcation in the multimedia system when you
switch the vehicle on.
You will receive information about the following points:
= The area of the vehicle that may have been
damaged.
= The force of the impact.
The following situation can lead to inadvertent
activation:
= The parked vehicle is moved, for example, in a
two-story garage.
\bDeactivate the tow-away alarm in order to
prevent inadvertent activation. If you deacti-
vate the tow-away alarm, collision detection
will also be deactivated.Driving and parking209

Driving and driving safety systems
Driving systems and your responsibility
Your vehicle is equipped with driving systems
which assist you in driving, parking and maneuver-ing the vehicle. The driving systems are only aids.
They are not a substitute for you paying attention
to your surroundings and do not relieve you of your responsibility pertaining to road traPc law.
The driver is always responsible for maintaining a
safe distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane. Pay attention to the traPc conditions at all
times and intervene when necessary. Be aware of
the limitations regarding the safe use of these systems.
Driving systems can neither reduce the risk of accident if you fail to adapt your driving style nor
override the laws of physics. They cannot always
take into account road, weather or traPc condi-
tions.
Information on vehicle sensors and cameras
Some driving and driving safety systems use cam- eras as well as radar or ultrasonic sensors to
monitor the area in front of, behind or next to the vehicle.
1Multifunction camera2Cameras in the outside mirrors3Front radar4Front camera5Corner radars6Ultrasonic sensors7Rear-view camera&WARNING Risk of accident due to restric-
ted detection performance of vehicle sen- sors and cameras
If the area around vehicle sensors or cameras
is covered, damaged or dirty, certain driving
and safety systems cannot function correctly.
There is a risk of an accident.
Keep the area around vehicle sensors or
cameras clear of any obstructions and
clean.Have damage to the bumper, radiator
grille or stone chipping in the area of the
front and rear windows repaired at a
qualiNed specialist workshop.Driving and parking211

In particular, keep the areas around the sensorsand cameras free of dirt, ice or slush
(  page 350). The sensors and cameras must
not be covered and the detection ranges around them must be kept free. Do not attach any addi-
tional license plate brackets, advertisements,
stickers or foils !

Functions of ABS
The Anti-lock Brake System (ABS) regulates the
brake pressure in critical driving situations:
= During braking, for instance, at maximum full-
stop braking or if there is insuPcient tire trac-
tion, the wheels are prevented from locking.
= Vehicle steerability while braking is ensured.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road con- ditions and can serve as a reminder to take extra
care while driving.
System limits = ABS is active from speeds of approx. 3 mph
(5 km/h).
= ABS may be impaired or may not function if a
malfunction has occurred and the yellow %
ABS warning lamp lights up continuously aser
the vehicle is started.
Functions of OM-road ABS
\bOM-road ABS is activated automatically when
you select the F or G drive program.
OM-road ABS is specially adapted for driving oM-
road:
= The front wheels lock cyclically during braking.
= The braking distance is shortened due to the
digging-in eMect.
System limits
= OM-road ABS functions at speeds below
25 mph (40 km/h).
= If OM-road ABS intervenes, the ability to steer
may be restricted.
Function of BAS&WARNING Risk of an accident caused by a
malfunction in BAS (Brake Assist System)
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased.
Depress the brake pedal with full force in
emergency braking situations. ABS pre-
vents the wheels from locking.
The Brake Assist System (BAS) supports your emergency braking situation with additional brake
force.
If you depress the brake pedal quickly, BAS will be
activated:
= BAS automatically boosts the brake pressure.
= BAS can shorten the braking distance.
= ABS prevents the wheels from locking.
The brakes will function as usual once you release the brake pedal. BAS will be deactivated.

Functions of ESPn&WARNING
Risk of skidding if ESP n
is
deactivated
If you deactivate ESP n
, ESP n
cannot carry out
vehicle stabilization.
ESP n
should only be deactivated in the
following situations.*NOTE Mercedes-AMG vehiclesObserve the notes in the Supplement.
You could otherwise fail to recognize
dangers.
The Electronic Stability Program (ESP n
) can moni-
tor and improve driving stability and traction in
the following situations within physical limits:
= When pulling away on wet or slippery roads.
= When braking.
= Vehicles with trailer hitch: in trailer operation
from speeds of 40 mph (65 km/h), if the vehi- cle/trailer combination begins to sway from
side to side.
= In strong crosswinds when you are driving
faster than 50 mph (80 km/h).
If the vehicle deviates from the direction desired
by the driver, ESP n
can stabilize the vehicle by
intervening in the following ways:
= One or more wheels are braked.
= The engine output is adapted according to the
situation.
ESP n
is deactivated if the

ETS/4ETS (Electronic Traction System)
ETS/4ETS traction control is part of ESP n
and
makes it possible to pull away and accelerate on a slippery road.
If you select the F or G drive program, a
special ETS system speciNcally suited to oM-road
terrain will automatically be activated.
ETS/4ETS can improve the vehicle\bs traction by
intervening in the following ways:
= The driven wheels are braked individually if
they spin.
= More drive torque is transferred to the wheel
or wheels with traction.
*nOuence of drive programs on ESP n
The drive programs enable ESP n
to adapt to dif-
ferent weather and road conditions as well as the
driver\bs preferred driving style. Depending on the
selected drive program, the appropriate ESP n
mode will be activated. You can select the drive
programs using the DYNAMIC SELECT switch (  page 192).Function of ESP n
Crosswind Assist
ESP n
Crosswind Assist detects sudden gusts of
side wind and helps the driver to keep the vehicle
in the lane:
= ESP n
Crosswind Assist is active at vehicle
speeds between approx. 47 mph (75 km/h)
and 125 mph (200 km/h) when driving
straight ahead or cornering slightly.
= The vehicle is stabilized by means of individual
brake application on one side.
Function of ESP n
trailer stabilization
&WARNING Risk of accident in poor road
and weather conditions
In poor road and weather conditions, the
trailer stabilization cannot prevent lurching of
the vehicle/trailer combination. Trailers with a
high center of gravity may tip over before
ESP n
detects this.
Always adapt your driving style to suit
the current road and weather conditions.When driving with a trailer, ESP n
can stabilize
your vehicle if the trailer begins to swerve from
side to side:
= ESP n
trailer stabilization is active above
speeds of 40 mph (65 km/h).
= Slight swerving is reduced by means of a tar-
geted, individual brake application on one
side.
= In the event of severe swerving, the operating
energy output is also reduced and all wheels
are braked.
ESP n
trailer stabilization may be impaired or may
not function if:
= The trailer is not connected correctly or is not
detected properly by the vehicle.Driving and parking215

HOLD function
HOLD function
The HOLD function holds the vehicle at a stand-
still without requiring you to depress the brake pedal, e.g. while waiting in traPc.
The HOLD function is only an aid. The responsibil-
ity for the vehicle safely standing still remains with the driver.
System limits
