The system may be impaired or may not function
particularly in the following situations:
If there is poor visibility, e.g. due to insufficient
R

able shade conditions or in rain, snow, fog or
heavy spray.
If there is glare, e.g. from oncoming traffic, the
R
sun or reflections.
If the windscreen in the area of the multifunc-
R
tion camera is dirty, or if the camera is misted
up, damaged or covered.

R
unclear lane markings are present for one
lane, e.g. around roadworks.
If the lane markings are worn, dark or cov-

R
short and thus the lane markings cannot be
detected.

R
