Active Lane Keeping Assist

General notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of multi-
function camera : at the top of the wind-
shield. Various different areas to the front,
rear and side of your vehicle are also moni-
tored with the aid of the radar sensor system.
Active Lane Keeping Assist detects lane
markings on the road and can warn you
before you leave your lane unintentionally. If
you do not react to the warning, a lane-cor-
recting application of the brakes can bring the
vehicle back into the original lane.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must
be operational
Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of accident nor override the laws of phys-
Driving systems
ics. Active Lane Keeping Assist cannot take
account of road and weather conditions. It
may not recognize traffic situations. Active
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 your lane.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane.
G WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
give an unnecessary warning and then
R
make a course-correcting brake application
to the vehicle
not give a warning or intervene
R
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:
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 reflections (e.g. when the road
surface is wet)
the windshield is dirty, fogged up, damaged
R
or covered, for instance by a sticker, in the
vicinity of the camera
the radar sensors in the front or rear bump-
R
ers or the radiator trim are dirty, e.g.
obscured by snow
there are no, several or unclear lane mark-
R
ings for a lane, e.g. in areas with road con-
struction work
the lane markings are worn away, dark or
R
covered up, e.g. by dirt or snow
