Lane Keeping Assist
Important safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognizelane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot giveawarning
There isarisk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
isarisk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane
Keeping Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. 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.
The Lane Keeping Assist does not keep the
vehicle in the lane.
The system may be impaired or may not
function if:
Rthere is poor visibility, e.g. due to
insufficient illumination of the road, or due
to snow, rain, fog or spray
Rthere is glare, e.g. from oncomingtraffic,
the sun or reflections (e.g. when the road
surface is wet)
Rthe windshield is dirty, fogged up, damaged
or covered, for instancebyasticker, in the
vicinity of the camera
Rthere are no, several or unclear lane
markings foralane, e.g. in areas with road
construction work
Rthe lane markings are worn away,dark or
covered up, e.g. by dirt or snow

Course-correcting brake application
GWARNING
Acourse-correctingbrake application cannot
alwayspreventacollision. There isarisk of
an accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makesacourse-correcting brake
application. Always maintainasafe distance
at the sides.
If Active Blind Spot Assist detectsarisk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is meant to assist you in avoiding a
collision.
Ifacourse-correcting brake application
occurs, red warning lampflashes in the
exterior mirror andadual warning tone
sounds. In addition, the display shown in the
lower image appears in the multifunction
display.
In very rare cases, the system may make an
inappropriate brake application. An
inappropriate course-correcting brake
application may be interrupted at any time if
you steer slightly in the opposite direction or
accelerate, for example.
The course-correcting brake application is
available in the speed range between
20 mph (30 km/h) and 120 mph (200 km/h).
Either no braking application, oracourse-
correcting brake application adapted to the
driving situation occurs if:
Rthere are vehicles or obstacles, e.g. crash
barriers, located on both sides of your
vehicle.
Ravehicle approaches you too closely at the
side.
Ryou have adoptedasporty driving style with
high cornering speeds.
Ryou clearly brake or accelerate.
