to change lanes, and a vehicle is detected in
the side monitoring range of Active Blind Spot

Course-correcting brake application
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 designed to help you avoid a col-
lision.
The course-correcting brake application is
available in the range between 30 km/ha nd
200 km/h.
If a course-correcting brake application
occurs, red warning lamp :flashes in the

WARNING
Active Blind Spot Assist is only an aid
designed to assist driving. It is not a substitute
for attentive driving. Automatic braking by the
system may not always be sufficien tto avoid
a collision. In such cases, you need to steer,
brake or accelerate yourself.
In very rare cases, the system may detect a
risk of collision where there is none and brake
in error near crash barriers or similar road
boundaries. Active Blind Spot Assist cannot
detect all traffic situations and road users.
Ensure at all times that there is sufficient lat- eral distance between you and other road
users or obstacles. You can, for example,
countersteer gently or depress the accelera-
tor pedal at any time to cancel inappropriate
braking action.
You are responsible for the vehicle's speed,
correc
tsteering and for braking in good time.
Always adap tyour driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
Either a very slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle.
R a vehicle approaches too closely on the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you brake or accelerate decisively.
R a driving safety system intervenes, such as
ESP ®
or PRE-SAFE ®
Brake.
R ESP ®
is deactivated.
R a loss of tyre pressure or a defective tyre is
detected.
Activating Active Blind Spot Assist
