deactivated.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.

Lane Keeping Assist
Important safety notes
G WARNING
Lane Keeping Assist does not keep your vehi-
cle 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 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
