Driving systems
262
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
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:
there is poor visibility, e.g. due to insuffi-
R
cient illumination of the road, or due to
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

in the vicinity of the camera

R
present for one lane, e.g. in a construction
area
the lane markings are worn away, dark or

the distance to the vehicle in front is too
R

detected
the lane markings change quickly, e.g.

merge
the road is narrow and winding
