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. 228

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 356). 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. Overview of driving systems and driving safety
