activation:
= The parked vehicle is moved, forexample, in a
two-storey garage.
% Deactivate tow-away protection in order to
pr
event inadvertent activation. If you deacti-
vate tow-away protection, collision detection

De

tection may be restricted in the following situa-
tions:

Driving systems and your responsibility
Your vehicle is equipped with driving systems
whic
h assist you in driving, parking and manoeu-
vring 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 maintain-
ing a safe distance to the vehicle in front, for vehi-
cle 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-
er
as as well as radar or ultrasonic sensors to
monitor the area in front of, behind or next to the
vehicle. 1

WARNING Risk of accident due t o restric-
ted detection performance of vehicle sen-
sors and cameras
If the area around vehicle sensors or cameras
is co
vered, 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
camer

as clear of any obstructions and
clean. 
Have damage to the bumper, radiator
g

rille or stone chipping in the area of the
front and rear windows repaired at a
qualiNed specialist workshop. Particularly, keep the areas around the sensors
and camer
as free of dirt, ice or slush
(  page 386). The sensors and cameras must not be covered and the detection ranges around
t
hem must be kept free. Do not attach additional
licence plate brackets, advertisements, stickers,
foils or foils to protect against stone chippings in
the detection range of the sensors and cameras.
Make sure that there are no overhanging loads
protruding into the detection range.
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 in the area
of the cameras on the front and rear windows
repaired at a qualiNed specialist workshop.

The Anti-lock Brake System (ABS) regulates the
br

ake pressure in critical driving situations:
= During braking, for instance, at maximum full-
stop braking or if there is insuPcient tyre 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 activ

e from speeds of approx. 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 b
y a
malfunction in BAS (Brake Assist System)
If BAS is malfunctioning, the braking distance
in an emer
gency braking situation is
increased. 
Depress the brake pedal with full force in
emer

gency braking situations. ABS pre-
vents the wheels from locking. The Brake Assist System (BAS) supports your
emer
gency braking situation with additional brake
force. Driving and parking
