sive Steering Assist and cornering function
Active Brake Assist can help you to minimize the
risk of a collision with vehicles, cyclists or pedes-
trians or to reduce the e ects of such a collision.
If Active Brake Assist has detected a risk of colli-
sion, a warning tone sounds and the L dis-
tance warning lamp lights up in the instrument
cluster.
® ®
V V ehicles wit ehicles with PRE-S h PRE-SAFE AFE : : depending on the coun-
try, an additional haptic warning occurs in the
form of slight, repeated tensioning of the seat
belt.
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 critical situa-
tion or apply the brake during autonomous brak-
ing, situation-dependent braking assistance
ackag age: e: Eva- occurs. The brake pressure increases up to maxi-
mum full-stop braking if necessary.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize
dangers ( page 155).
/
If autonomous braking or situation-dependent
braking assistance has occurred, display
appears in the Instrument Display and then auto-
matically goes out a er a short time.
If the autonomous braking function or the situa-
tion-dependent braking assistance is triggered,
additional preventive measures for occupant pro-
®
tection (PRE-SAFE ) may also be initiated.
& 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.
1
Be prepared to brake or swerve if neces-
#
sary.
Also observe the system limits of Active Brake
Assist.
