The system may be impaired or may not func-
tion if:
R
there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray.
R
there is glare, e.g. from oncoming traffic,
the sun, or reflection from other vehicles.
R
the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
R
several or no lane markings for a single lane
are present.
R
the lane markings are worn away, dark or
covered up, e.g. by dirt or snow.
R
the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected.
R
the lane markings on the road are unclear,
e.g. near roadworks.
R
the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge.
R
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 recognise dangers in time,
cause an accident and injure yourself and oth-
ers.
A warning may be given if 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 nec-
essary and in good time if you cross the lane
marking, the system recognises certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
R
you approach the outer lane marking on a
bend.
R
the road has very wide lanes, e.g. a motor-
way.
R
the system recognises solid lane markings.
The warning vibration occurs later if:
R
the road has narrow lanes.
R
you cut the corner on a bend.
No warning vibration occurs if:
R
you clearly and actively steer, brake, or
accelerate.
R
you cut the corner on a sharp bend.
R
a driving safety system intervenes, such as
ABS, BAS or ESP
®
.
R
you have switched on the turn signals. In
this event, the warnings are suppressed for
a certain period of time.
