Lane Keeping Assist

Important safety notes
G WARNING
Lane Keeping Assist does not keep your
vehicle in its lane. It is only an aid and may
detect the lane markings on the road
incorrectly or not at all.
The system may be impaired or may not
function if:
there is poor visibility, e.g. due to
R
insufficient illumination of the road, or due
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.
several or no lane markings for a single lane
R
are present.
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.
