Driving and parking 199
If Active Brake Assist has detected a risk of colli-
sion, a warning tone sounds and the L warn-
ing lamp lights up.
®
Vehicles with PRE-SAFE : 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 brake force boosting.
The brake pressure increases up to maximum full-
stop braking if necessary.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize
dangers ( page 176).
