brakes can bring the vehicle back into the
original lane.
If you select km
the Display Unit Speed-/Odometer
tion ( page 232), Active Lane Keeping Assist
Y
is activated starting at a speed of 60 km/h. If
the miles display unit is selected, the assis-
tance range begins at 40 mph.
Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of accident nor override the laws of phys-
ics. Lane Keeping Assist cannot take into
account the road, traffic and weather condi-
tions. Lane Keeping Assist is merely an aid.
You are responsible for the distance to the
vehicle in front, for vehicle speed, for braking
in good time and for staying in your lane.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane.
G WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
give an unnecessary warning and then
R
make a course-correcting brake application
to the vehicle
not give a warning or intervene
R
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 func-
tion if:
there is poor visibility, e.g. due to insuffi-
R
cient illumination of the road, or due to
snow, rain, fog or spray
there is glare, e.g. from oncoming traffic,
R
the sun or reflections (e.g. when the road
surface is wet)
on the on-board computer in
the windshield is dirty, fogged up, damaged
R
or covered, for instance by a sticker, in the
vicinity of the camera
there are no, several or unclear lane mark-
func-
R
ings for a lane, e.g. in areas with road con-
struction work
the lane markings are worn away, dark or
R
covered up, e.g. by dirt or snow
the distance to the vehicle in front is too
R
small and the lane markings thus cannot be
detected
the lane markings change quickly, e.g.
R
lanes branch off, cross one another or
merge
the road is narrow and winding
R
there are strong shadows cast on the road
R
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 steer-
ing 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 recognizes certain con-
ditions 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 high-
R
way.
the system recognizes solid lane markings.
R
The warning vibration occurs later if:
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
