If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
road, weather or traffic conditions. Lane
Keeping Assist is only an aid. You are respon-
sible for the distance to the vehicle in front,
for vehicle speed, for braking in good time,
and for staying in lane.
Lane Keeping Assist does not keep your vehi-
cle in its lane.
The system may be impaired or may not func-
tion if:
R
there is poor visibility, e.g. due to insuf-
ficient illumination of the road, or due to
snow, rain, fog or spray
R
there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
R
the windscreen is dirty, misted up, dam-
aged or covered, for instance by a sticker,
in the vicinity of the camera
R
no, or several, unclear lane markings are
present for one lane, e.g. in a construction
area
R
the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R
the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R
the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R
the road is narrow and winding
R
there are highly variable shade conditions
on the road
No warning occurs if:
R
a lane marking is crossed at speed
R
you have switched on the turn signals. In
this case, the warnings are suppressed for
a certain period of time
R
you cut the corner on a sharp bend
