WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
is a risk of an accident.
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
Lane Keeping Assist does not keep your vehi-
cle in its lane.
The system may be impaired or may not func-
tion if:
there is poor visibility, e.g. due to insuffi-
R

snow, rain, fog or spray
there is glare, e.g. from oncoming traffic,
R
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
the windscreen is dirty, misted up, dam-
R
aged or covered, for instance by a sticker
in the vicinity of the camera
no, or several, unclear lane markings are
R
present for one lane, e.g. in a construction
area
the lane markings are worn away, dark or
R
covered up, e.g. by dirt or snow
the distance to the vehicle in front is too
R
small and the lane markings thus cannot be
detected
the lane markings change quickly, e.g.
R
lanes branch off, cross one another or
merge
the road is narrow and winding

there are highly variable shade conditions
