W WARNING ARNING Risk of an accident caused by

Brake Assist
Active Brake Assist cannot always clearly iden-
tify objects and complex tra c situations.
In such cases, Active Brake Assist might:
R
Give a warning or brake without reason
R
Not give a warning or not brake
Active Brake Assist is only an aid. The driver is
responsible for maintaining a su ciently safe
distance to the vehicle in front, vehicle speed
and for braking in good time.
#
Always pay careful attention to the tra c
situation; do not rely on Active Brake
Assist alone.
#
Be prepared to brake or swerve if neces-
sary.
If Active Brake Assist is deactivated or the func-
tions are restricted, e.g. due to activation of
another driving system, the ê display message
will appear on the driver's display.
If the system is unavailable due to dirty or dam-
aged sensors or due to a malfunction, or if the
functions are restricted, the Ó warning lamp
will appear on the driver's display.
Also observe the system limits of Active Brake
Assist.
