G 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.
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
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
R
there are highly variable shade conditions

R
obstacle or change lane quickly.

R
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system detects certain condi-
tions and warns you accordingly.

you approach the outer lane marking on a
R
bend
the road has very wide lanes, e.g. a motor-
R
way
the system detects solid lane markings
