This function is available in the range between
40 mph and 120 mph (60 km/h and 200 km/h).
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 seconds.
Important safety notes
G
WARNING
Lane Keeping Assist cannot always clearly
detect lane markings.
In such cases, Lane Keeping Assist can:
give an unnecessary warning
R
not give a warning
R
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Lane Keeping Assist alerts you.
G
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 Keep-
ing Assist.
Lane Keeping Assist can neither reduce the risk
of an accident if you fail to adapt your driving
style nor override the laws of physics. Lane
Keeping Assist cannot take into account the
road, traffic and weather conditions. Lane Keep-
ing Assist is merely an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
The Lane Keeping Assist does not keep the vehi-
cle in the 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 windshield is dirty, fogged up, damaged or
R
covered, for instance by a sticker, in the vicin-
ity of the camera
there are no, several or unclear lane markings
R
for a lane, e.g. in areas with road construction
work
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 roadway
