▌Function of Active Brake Assist
Active Brake Assist consists of:

up M or
Active Brake Assist can help you to minimise the
risk of a collision with vehicles or pedestrians or
to reduce the effects of such a collision.
If Active Brake Assist has detected a risk of colli-
sion, a warning tone sounds and the L warn-
ing lamp lights up in the Instrument Display.
up M.
If you do not react to the warning, autonomous
braking can be initiated in critical situations.
In especially critical situations, Active Brake Assist
can initiate autonomous braking directly. In this
case, the warning lamp and warning tone occur
simultaneously with the braking application.
If you apply the brake yourself in a situation
detected as critical by Active Brake Assist, or
apply the brake during autonomous braking, situa-
tion-dependent brake force boosting occurs. The
brake pressure increases up to maximum full-stop
braking if necessary.
If the autonomous braking function or the situa-
tion-dependent brake force boosting is triggered,
additional preventive measures for occupant pro-
tection (PRE-SAFE

& WARNING Risk of an accident caused by
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly iden-
tify objects and complex traffic 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 sufficiently safe
distance to the vehicle in front, vehicle speed
and for braking in good time.
Always pay careful attention to the traffic
#
situation; do not rely on Active Brake
Assist alone.
Be prepared to brake or swerve if neces-
#
sary.
Observe the system limitations of Active Brake
Assist.
