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. Ter-
minate the intervention in a non-critical driv-
ing 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 reflection from other vehicles (e.g. if
the road surface is wet)
R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
R
the radar sensors in the front or rear bumpers
or the radiator trim are dirty, e.g. obscured by
snow
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 cov-
ered 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 detec-
ted
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
If no vehicle is detected in the adjacent lane and
broken lane markings are detected, no lane-cor-
recting brake application is made.
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.
Lane-correcting brake application
If you leave your lane, under certain circumstan-
ces the vehicle will brake briefly on one side.
This is meant to assist you in bringing the vehicle
back to the original lane.
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.
If a lane-correcting brake application occurs,
display : appears in the multifunction display.
The brake application also slightly reduces vehi-
cle speed.
A lane-correcting brake application can be made
after driving over a lane marking detected as
being solid or broken. Before this, a warning
must be given by means of intermittent vibration
in the steering wheel. In addition, a lane with
lane markings on both sides must be recog-
nized.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. Oncoming vehicles, over-
taking vehicles and vehicles in adjacent lanes
can be detected.
A further lane-correcting brake application can
only occur after your vehicle has returned to the
original lane.
No lane-correcting brake application occurs if:
R
you clearly and actively steer, brake or accel-
erate.
R
you cut the corner on a sharp bend.
