the road and can warn you before you leave your
lane unintentionally.
This function is available in a speed range
between 60 km/h and 200 km/h.

over a lane marking. It will warn you by means of
intermittent vibration through 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:
issue an unnecessary warning
R
not issue 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.
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
in the following situations:
poor visibility, e.g. due to insufficient illumi-
R
nation of the road, or due to snow, rain, fog or
spray
glare, e.g. from oncoming traffic, the sun or
R
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
there are no lane markings, or several unclear
R
lane markings for one lane are present, e.g.
around construction sites
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 short
R
and thus the lane markings cannot be detec-
ted
the lane markings change quickly, e.g. lanes
R
branch off, cross one another or merge
the road is very narrow and winding
R
there are highly variable shade conditions on
R
the roadway
