Important safety notes
G
WARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
give an unnecessary warning
R
not give a warning
R
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account the
road, traffic and weather conditions. Lane Keep-
ing Assist is merely an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
The Lane Keeping Assist does not keep the vehi-
cle in the lane.
The system may be impaired or may not function
if:
there is poor visibility, e.g. due to insufficient
R
illumination of the road, or due to snow, rain,
fog or spray
there is glare, e.g. from oncoming traffic, the
R
sun or reflections (e.g. when the road surface
is wet)
the windshield is dirty, fogged up, damaged or
R
covered, for instance by a sticker, in the vicin-
ity of the camera
there are no, several or unclear lane markings
R
for a lane, e.g. in areas with road construction
work
the lane markings are worn away, dark or cov-
R
ered up, e.g. by dirt or snow
Driving systems
the distance to the vehicle in front is too small
R
and the lane markings thus cannot be detec-
ted
the lane markings change quickly, e.g. lanes
R
branch off, cross one another or merge
the road is narrow and winding
R
there are strong shadows cast on the road
R
Switching on Lane Keeping Assist
Switch on Active Lane Keeping Assist using
X
the on-board computer; to do so, select
Standard or Adaptive
If you drive at speeds above 40 mph
(60 km/h) and lane markings are detected,
the lines in the assistance graphics display
( page 171) are shown in green. Lane Keep-
Y
ing Assist is ready for use.
Standard
If Standard is selected, no warning vibration
occurs if:
you switch on the turn signals. In this event,
R
the warnings are suppressed for a certain
period of time.
a driving safety system intervenes, such as
R
®
ABS, BAS or ESP .
Adaptive
When Adaptive is selected, no warning vibra-
tion occurs if:
you switch on the turn signals. In this event,
R
the warnings are suppressed for a certain
period of time.
a driving safety system intervenes, e.g. ABS,
R
®
BAS or ESP .
you accelerate hard, e.g. kickdown.
R
you brake hard.
R
you steer actively, e.g. swerve to avoid an
R
obstacle or change lanes quickly.
you cut the corner on a sharp bend.
R
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system recognizes certain conditions
and warns you accordingly.
The warning vibration occurs earlier if:
you approach the outer lane marking on a
R
bend.
the road has very wide lanes, e.g. a highway.
R
the system recognizes solid lane markings.
