Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of camera :
mounted at the top of the windshield. Active
Lane Keeping Assist detects lane markings on
the road and warns you before you leave your
lane unintentionally. If you do not react to the
warning, a lane-correcting application of the
brakes can bring the vehicle back into the
original lane.

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-
ics. Lane Keeping Assist cannot take into
account the road, traffic and weather condi-
tions. Lane Keeping Assist is merely 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.

There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially

minate the intervention in a non-critical driv-
ing situation.
