Mercedes-Benz 2013 C Class Sedan - Manual (Page 196)

G
WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
R
give an unnecessary warning and then
make a course-correcting brake application
to the vehicle
R not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you.
Terminate the intervention in a non-critical
driving situation.
The system may be impaired or may not
function if:
R
there is poor visibility, e.g. due to
insufficient illumination of the road, or due
to snow, rain, fog or spray
R
there is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
R
the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R
there are no, several or unclear lane
markings for a lane, e.g. in areas with road
construction work
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 in 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
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:
R
you approach the outer lane marking on a
bend.
R
the road has very wide lanes, e.g. a
highway.
R
the system recognizes 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
application.
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
driving 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 on the side for
other traffic or obstacles.
If you leave your lane, under certain
circumstances the vehicle will brake briefly
