Driving and parking
The system may be impaired or may not
function if:
Rthere is poor visibility, e.g. due to
insufficient illumination of the road, or due
to snow, rain, fog or spray.
Rthere is glare, e.g. from oncoming traffic,
the sun, or reflection from other vehicles.
Rthe windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera.
Rseveral or no lane markings for a single lane
are present.
Rthe lane markings are worn away, dark or
covered up, e.g. by dirt or snow.
Rthe distance to the vehicle in front is too
small and the lane markings thus cannot be
detected.
Rthe lane markings on the road are unclear,
e.g. near roadworks.
Rthe lane markings change quickly, e.g.
lanes branch off, cross one another or
merge.
Rthe 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:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a
freeway.
Rthe system recognizes solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.
Ryou cut the corner on a bend.
No warning vibration occurs if:
Ryou clearly and actively steer, brake, or
accelerate.
Ryou cut the corner on a sharp bend.
Ra driving safety system intervenes, such as
ABS, BAS or ESP ® .
Ryou switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
