Active Brake Assist
▌Function of Active Brake Assist
Active Brake Assist consists of the following func-
tions:
Distance warning function
R
Autonomous braking function
R
Situation-dependent braking assistance
R
Evasive Steering Assist (country-specific)
R
Active Brake Assist can help you to minimise the
risk of a collision with vehicles, cyclists or pedes-
trians 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 dis-
tance warning lamp lights up.
In the Assistance menu, an insufficient distance
1 to the vehicle in front is displayed in red. If you
further reduce the distance, the vehicle in front is
also highlighted in red. When the system detects a
P223 0288 02
risk of collision, red radar waves
front of the vehicle.
®
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.
% Vehicles with active ambient lighting: if
ing assistance is activated, the Active Brake
Assist warning is also accompanied by ambi-
ent lighting ( page 162).
/
If you do not react to the warning, autonomous
braking can be initiated in critical situations.
In particularly critical situations, Active Brake
Assist can also initiate autonomous braking
directly. In this case, the warning lamp and warn-
ing 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
occurs. The brake pressure increases up to maxi-
mum full-stop braking if necessary.
