Lane Keeping Assist
Important safety notes
Lane Keeping Assist monitors the area in front of your vehicle by means of a camera at the top of the windshield. Lane Keeping Assist detects lane markings on the road and warns you before you leave your lane unintentionally.

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
insufficient illumination of the road, or due
to snow, rain, fog or spray.
- there is glare, e.g. from oncoming traffic,
the sun, or reflection from other vehicles.
- the windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera.
- several or no lane markings for a single lane
are present.
- the lane markings are worn away, dark or
covered up, e.g. by dirt or snow.
- the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected.
- the lane markings on the road are unclear,
e.g. near roadworks.
- the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge.
- the road is narrow and winding.
Lane Keeping Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the vehicle's speed, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.
A warning can be given when a front wheel passes over a lane marking. It will warn you by means of intermittent vibration in the steering wheel for up to 1.5 seconds.
In order that you are warned only when necessary and in good time if you cross the lane marking, the system recognizes certain conditions and warns you accordingly.
The warning vibration occurs earlier if:
- you approach the outer lane marking on a
bend.
- the road has very wide lanes, e.g. a
freeway.
- the system recognizes solid lane markings.
The warning vibration occurs later if:
- the road has narrow lanes.
- you cut the corner on a bend.
No warning vibration occurs if:
- you clearly and actively steer, brake or
accelerate.
- you cut the corner on a sharp bend.
- a driving safety system intervenes, e.g.
ABS, BAS or ESP®.
- you switch on the turn signals. In this event, the warnings are suppressed for a certain period of time.
