sensor limitations
"Collision Warning with Auto Brake and
Cyclist and Pedestrian Detection" is an aid to
assist the driver when there is a risk of collid-
ing with a pedestrian, bicycle or vehicle in
front that are stationary or moving in the same
direction.
The function uses the car's camera sensor,
which has certain limitations.
The car's camera sensor is also used - as
well as by Collision Warning with Auto Brake
- by the functions:
•
Automatic main/dipped beam dim-
ming (p. 80)
•
Road sign information (p. 177)
•
Driver Alert Control - DAC (p. 219)
•
Lane Keeping Aid (p. 223)
NOTE
Keep the windscreen surface in front of the
camera sensor free from ice, snow, mist
and dirt.
Do not stick or attach anything to the
windscreen in front of the camera sensor
as this may reduce effectiveness or cause
one or more of the systems dependent on
the camera to stop working.
The camera sensors have limitations similar
to the human eye, i.e. they "see" worse in

darkness, heavy snowfall or rain and in thick
fog for example. Under such conditions the
functions of camera-dependent systems
could be significantly reduced or temporarily
disengaged.
Strong oncoming light, reflections in the car-
riageway, snow or ice on the road surface,
dirty road surfaces or unclear lane markings
could also significantly reduce camera sensor
function when it is used to scan the carriage-
way and detect pedestrians and other vehi-
cles.
The field of vision of the camera sensor is lim-
ited, which is why pedestrians, cyclists and
vehicles cannot be detected in some situa-
tions, or they are detected later than anticipa-
ted.
During very high temperatures the camera is
temporarily switched off for about 15 minutes
after the engine is started in order to protect
camera functionality.
Fault tracing and action
If the display shows the message
Windscreen Sensors blocked
means that the camera sensor is blocked and
cannot detect pedestrians, cyclists, vehicles
or road markings in front of the car.
At the same time, this means that - besides
