& W W ARNING
ARNING Risk of an accident caused by
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly iden-
tify objects and complex tra c situations.
In such cases, Active Brake Assist might:
Give a warning or brake without reason
R
Not give a warning or not brake
R
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.
