situation and keep within the lane, espe-

WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
is a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane
Keeping Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
road, weather or traffic conditions. Lane Keep-
ing Assist is only an aid. You are responsible
for the distance to the vehicle in front, for
vehicle speed, braking in good time and for
staying in your 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 windshield is dirty, fogged up, damaged
R
or covered, for instance by a sticker, in the
vicinity of the camera
there are no lane markings, or several
R
unclear lane markings for one lane, e.g.
around construction sites
the lane markings are worn away, dark or

the distance to the vehicle in front is too
R
short and thus the lane markings cannot be
detected

the road is narrow and winding
R
there are highly variable shade conditions
