Information on collision detection when a vehicle
is parked
If a collision is detected when the tow-away alarm
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.
You can permanently deactivate collision
detection via the multimedia system
(  page 177).\bIf the battery is severely discharged, the func-
tion for detecting a collision with a parked vehicle will automatically be deactivated tofacilitate the next engine start.
System limits
Detection may be restricted in the following situa- tions:

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 ofaccident 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.

&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.
In particular, keep the areas around the sensors
and cameras free of dirt, ice or slush
(  page 313). 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.
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.

Function 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.
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
