Collision warning system with brake support*

Limitations

The visual warning signal may be difficult to
notice in strong sunlight or when sunglasses
are being worn. For this reason always acti-
vate the warning sound during such condi-
tions.
NOTE
The visual warning signal can be temporari-
ly disengaged in the event of high passen-
04
ger compartment temperature caused by
strong sunlight for example. If this occurs
then the warning sound is activated even if
it is deactivated in the menu system.
Warnings may not appear if the distance to
the vehicle in front is very small or if steering
wheel and pedal movements are large, e.g. a
very active driving style.
Warnings may be triggered late, be absent or
triggered unnecessarily if the traffic situation
means that the radar sensor cannot accu-
rately detect a vehicle in front. The collision
warning system uses the same radar sensors
as adaptive cruise control. For more informa-
tion on the radar sensor and its limitations,
see page 140.
An absent or late warning means that there is
no brake support or it comes late.
142
The incorrect warnings may be in the form of
both audio and visual signals. One way of re-
ducing the number of incorrect warnings is to
reduce the warning distance.
