Active Lane Keeping Assist

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.

R
are present.

to snow, rain, fog or spray.
there is glare, e.g. from oncoming traffic,
R
the sun, or reflection from other vehicles.
the windshield is dirty, fogged up or
R
covered, for instance by a sticker, in the
vicinity of the camera.
the lane markings are worn away, dark or
R
covered up, e.g. by dirt or snow.
the distance to the vehicle in front is too
R
small and the lane markings thus cannot be
detected.
the lane markings on the road are unclear,
R
e.g. near roadworks.
