Functions of Active Lane Keeping Assist
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera 1. It serves to protect you against unin‐
tentionally leaving your lane. You may also be
warned by a vibrating message from the steering
wheel and by the status symbol flashing in the
instrument display. In addition, you may be gui‐
ded back into your lane by a lane-correcting
brake application. A relevant message appears in
the instrument display.
The warning is issued when the following condi‐
tions are met at the same time:
The driving system detects lane markings.
R
A front wheel passes over the lane markings.
R
A lane-correcting brake application occurs when
the following conditions are met:

R
markings on both sides of the vehicle.
Driving and parking 151
A front wheel drives over a solid lane mark‐
R
ing.
A relevant message appears in the instrument
display.
The brake application is available in the speed
range between approximately 40 mph (60 km/h)
and 100 mph (160 km/h).
You can either deactivate the Active Lane Keep‐
ing Assist warning or switch off the system com‐
pletely.
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. It can‐
not take into account road, weather or traffic
conditions. The driving system is an aid for when
you unintentionally leave or cross the lane and
not a system for automatically keeping to the
lane. You are responsible for the distance to the
vehicle in front, for vehicle speed, braking in good
time and for staying in your lane.
If a lane-correcting brake application from Active
Lane Keeping Assist occurs, display
in the multifunction display.
