Course-correcting brake application

WARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of
an accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake
application. Always maintain a safe distance
at the sides.
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, ; 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, 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.
