Lane keeping system
(Lane Assist)
Introduction to the topic
Within the system limits, the lane keep-
ing system (Lane Assist) helps the driver
to stay in lane. The function is not de-
signed to keep the vehicle in lane auto-
matically, nor is it suited to this purpose.
Using a camera in the windscreen, the lane
keeping system detects road lane markings
on the road. If your vehicle moves too close
to a recognised road lane marking, the sys-
tem will warn the driver with a corrective
steering intervention. The corrective steering
intervention can be overridden by the driver
at any time.
System limits
Use the lane keeping system only on motor-
ways and well-developed country roads.
