Lane keep assist
Lane keep assist helps to avoid
crashes due to unintentional lane
departures. A front camera located at the top of the windscreen observes
the lane markings between which the
vehicle is driving. If the vehicle
approaches a lane marking, the
steering wheel is gently turned to
position the vehicle back into the lane. The driver will then notice a turning
movement of the steering wheel. Turn steering wheel in same direction, ifsystem steers not sufficient. Turn
steering wheel gently into opposite
direction, if lane change is intended.
When the system steers to correct the trajectory of the vehicle, a flashes
yellow in the instrument cluster.
A warning message in the Driver
Information Centre accompanied by a
warning chime alerts the driver when
immediate driver´s action is required.
Unintended lane departure is not
assumed by the system when the turn lights are operated and during 20 s
after turn lights have been switched off.
Notice
The system may be switched off if it
detects lanes which are too narrow, too wide or too curved.

fullfilled:
