R
There is a risk of an accident.

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 Keep-
ing Assist can neither reduce the risk of an acci-
dent 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 responsible 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 vehicle
in its lane.
The system may be impaired or may not function
if:
there is poor visibility, e.g. due to insufficient
R
illumination of the road, or due to snow, rain,
fog or spray
there is glare, e.g. from oncoming traffic, the
R
sun or reflection from other vehicles (e.g. if
the road surface is wet)
the windscreen is dirty, misted up, damaged
R
or covered, for instance by a sticker, in the
vicinity of the camera
no or several, unclear lane markings are pres-
R
ent for one lane, e.g. in a construction area
the lane markings are worn away, dark or cov-
R
ered up, e.g. by dirt or snow
the distance to the vehicle in front is too small
R
and the lane markings thus cannot be detec-
ted
the lane markings change quickly, e.g. lanes
R
branch off, cross one another or merge
the road is narrow and winding
R
there are highly variable shade conditions on
R
the road
