if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
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
(e.g. if the road surface is wet)
R
the windscreen is dirty, misted up, dam-
aged or covered, for instance by a sticker
in the vicinity of the camera
R
no, or several, unclear lane markings are
present for one lane, e.g. in a construction
area
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 change quickly, e.g.
lanes branch off, cross one another or
merge
R
the road is narrow and winding
R
there are highly variable shade conditions
on the roadway
R
no vehicle is detected in the adjacent lane
and there are broken lane markings
Warning vibration through the steering
wheel
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.
Lane-correcting brake application
G
WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original
lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
G
WARNING
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropriate
brake application, e.g. after intentionally driv-
ing over a solid lane marking. There is a risk
of an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance to the side for
other traffic or obstacles.
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is intended to help you return the
vehicle to the original lane.
This function is available in the range between
60 km/h and 200 km/h.
A lane-correcting brake application can only
be made after driving over a solid, recognis-
able lane marking. Before this, a warning
must have been issued by means of intermit-
tent vibration through the steering wheel. In
addition, a lane with lane markings on both
