If Active Blind Spot Assist detects a risk 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.
If a course-correcting brake application
occurs, red warning lamp : flashes in the
exterior mirror and a dual warning tone
sounds. In addition, the message shown in
the illustration appears in the multifunction
display.
The course-correcting brake application is
available in the speed range between 20 mph
(30 km/h) and120 mph (200km/h).
Either no braking application, or a course-
correcting brake application adapted to the
driving situation occurs if:
there are vehicles or obstacles, e.g. crash
R
barriers, located on both sides of your
vehicle.
a vehicle approaches you too closely at the
R
side.
you have adopted a sporty driving style with
R
high cornering speeds.
you clearly brake or accelerate.

®

may detect the lane markings on the road
incorrectly or not at all.
The system may be impaired or may not
function if:
there is poor visibility, e.g. due to
R
inadequate illumination of the road surface,
snow, rain, fog or spray.
there is glare, e.g. from oncoming traffic,
R
the sun, or reflection from other vehicles.
the windshield is dirty, fogged up or
R
covered, for instance by a sticker, in the
vicinity of the camera.
several or no lane markings for a single lane
R
are present.
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 as a result the lane markings
cannot be recognized.
the lane markings on the road are unclear,
R
e.g. near roadworks.
