Important safety notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of a camera

Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally. If you do not react to the
warning, a lane-correcting application of the
brakes can bring the vehicle back into the
original lane.
