Function of Active Lane Keeping Assist
Active Lane Keeping Assist monitors the area in
front of your vehicle bymeans of multifunction
camera 1. Yo

ing wheel in thefo llowing circums tances:
RAc tive Lane Keeping Assist de tects lane
markings.
RA front wheel passes over the lane markings.
Whe ther a warning is issued and when this
occurs also depends on the selected sensitivity
setting (s tanda rdor adaptive).
If yo ufa ilto adapt your dr ivingst yle, Ac tive Lane
Ke eping Assist can neither reduce therisk of an
accident nor override the la wsof ph ysics. It can‐
not take into account road, weather or traf fic

ve hicle in front, forve hicle speed, for braking in
good time and forst ay ing in your lane.
Ve hicles with Lane Tracking pac kage:if th e
lane markings are solid lines and you do not

Driving Assistance Plus pa ckage: ifyo u do not re
act tothewa rning, a lane-cor recting brake
application can bring theve hicle back into the
original lane. In the case of a broken lan

e mark‐
ing being de tected, a brake application will only
be made if a vehicle has been de tected in the
adjacent lane. Oncoming vehicles, overtaking
ve hicles and vehicles in adjacent lanes can be
de tected.
The brake application is available in the speed
ra nge between 40 mph (60 km/h) and 120mp h
(200 km/h).
