Speed-/odometer: function on the on-board

Important safety notes
If you fail to adapt your driving style, Active
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
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in the lane.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane.

WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
R
give an unnecessary warning and then
make a course-correcting brake application
to the vehicle
R
neither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not func-
tion if:
R
there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R
there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
R
the windscreen is dirty, misted up, dam-
aged or covered, for instance by a sticker
in the vicinity of the camera
R
no, or several, unclear lane markings are
present for one lane, e.g. in a construction
area
R
the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R
the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R
the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R
the road is narrow and winding
R
there are highly variable shade conditions
on the roadway
R
no vehicle is detected in the adjacent lane
and there are broken lane markings
Warning vibration through the steering
wheel
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.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognises certain con-
ditions and warns you accordingly.
