Driving and driving safety systems
Driving systems and your responsibility
Your vehicle is equipped with driving systems that
assist you in driving, parking and maneuvering thevehicle. The driving systems are only aids. Theyare 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
172Driving and parking

limitations regarding the safe use of these sys-tems.
Driving systems can neither reduce the risk of an 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.\bSome driving systems can regulate or limit the speed to a previously set value. Draw atten-tion to the stored speed when changing driv-
ers.
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.
Keep the areas around the sensors and cameras
in particular free of dirt, ice and slush (  page 290). The sensors and cameras must
not be covered and the detection areas around them must be kept clear. Do not attach additional
license plate bracket, advertisements, stickers, wraps or stone chip protection Nlms in the detec-
tion range of the sensors and cameras. Make sure
Driving and parking173

that there are no overhanging loads protruding
into the detection area.
If there is damage to a bumper or the radiator grille, or aser an impact, have the function of the
sensors checked at a qualiNed specialist work-
shop. Have damage or stone chipping around the cameras on the front and rear passenger com-
partment windows repaired at a qualiNed special-
ist workshop.

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.
174Driving and parking

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 ) 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 brakeforce.
If you depress the brake pedal quickly, BAS is
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 is deactivated.
Functions of ESP n
&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.Driving and parking175

The Electronic Stability Program (ESPn
) 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.
= In strong side winds 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

HOLD function

qHOLD 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
The HOLD function is only intended to provide assistance when driving and is not a suPcient
means of safeguarding the vehicle against rolling
away when stationary.
= The incline must not be greater than 30%.

qActivating/deactivating the HOLD function&WARNING Risk of an accident due to the
HOLD function being active when you
leave the vehicle
If the vehicle is only braked with the HOLD
function it could, in the following situations,
roll away:
= If there is a malfunction in the system or in
the power supply.
= If the HOLD function is deactivated by
depressing the accelerator pedal or brake
pedal, e.g. by a vehicle occupant.
Always secure the vehicle against rolling away before you leave it.
