Active Lane Keeping Assist is able to detect when the vehicle is unintentionally drifting out of its lane, to warn the driver and to guide the vehicle back on course.

Active Lane Keeping Assist intervenes, braking when the vehicle unintentionally drifts across continuous lines. In the case of broken lane marking lines, an intervention only takes place if the radar sensors detect the danger of a collision on the adjacent lane.

Available only in conjunction with Driving Assistance Plus Package.


The system operates in the speed range from 60 to 200 km/h; it can be switched on and off and its sensitivity can be adjusted in the instrument display.
