Active Lane Keeping Assist
▌Function of Active Lane Keeping Assist
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of the multifunction
camera (
page 173). It serves to protect you
/
against unintentionally leaving your lane. You will
be warned by vibration pulses in the steering
wheel and guided by a course-correcting brake
application back into your lane.
Active Lane Keeping Assist is available in the
speed range between 60 km/h and 200 km/h.
Active 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. It cannot
take into account road, weather or traffic condi-
tions. Active Lane Keeping Assist is only an aid.
You are responsible for maintaining a safe dis-
tance to the vehicle in front, for vehicle speed, for
braking in good time and for staying in lane.
If a lane-correcting brake application occurs, dis-
