Important safet ynotes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of acciden tnor override the laws of
physics. Active Lane Keeping Assist cannot
take into account road, weather or traffic
conditions. It cannot detect possible road and
traffic conditions. Active Lane Keeping Assist
is only an aid. You are responsible for the
distance to the vehicle in front,f or vehicle
speed, for braking in good time and for
staying in your lane. Active Lane Keeping Assist cannot
continuously 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:
R give an unnecessary warning and then
make acourse-correcting brake application
to the vehicle
R not give awarning or intervene
There is arisk 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 anon-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 asticker, in the
vicinit yofthe camera
R the radar sensors in the front or rear
bumper or in the radiator grill are dirty, e.g.
due to snow
R there are no, several or unclear lane
markings for alane, e.g. in areas with road
construction work
R the lane markings are worn away,d ark 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 214

by means of intermittent vibration in the
steering wheel for up to 1.5 seconds.
Lane-correcting brake application G
WARNING
Al ane-correcting brake application cannot
always bring the vehicle back into the original
lane. There is arisk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes alane-correcting brake
application. G
WARNING
Active Lane Keeping Assist does not detect
traffic conditionsorr oad users. In very rare
cases, the system may make an inappropriate
brake application, e.g. after intentionally
driving over asolid 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
on one side. This is meant to assist you in
bringing the vehicle back to the original lane.
If al ane-correcting brake application occurs,
display 001Aappears in the multifunction
display.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
Al ane-correcting brake application can only
be made after driving over asolid,
recognizable lane marking. Before this, a
warning must be given by means of
intermittent vibration in the steering wheel.
In addition, alane with lane markings on both
sides must be recognized. The brake
application also slightly reduces vehicle
speed.
i Afurther 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
accelerate.
R you cut the corner on asharp bend.
R you have switched on the turn signals.

lock if you brake hard, for example.
The steerability and braking characteristics may be severely
affected. The braking distance in an emergency braking situation
can increase.
If ESP ®

is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident.
