Active Brake Assist
Function of Active Brake Assist
Active Brake Assist consists of the following
functions:
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
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 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 risk of collision, red radar waves
appear in front of the vehicle.
®
Vehicles with PRE-SAFE : depending on the
country, an additional haptic warning occurs in
the form of slight, repeated tensioning of the
seat belt.
% Vehicles with active ambient lighting: if
Warning assistance is activated, the Active
Brake Assist warning is also accompanied by
ambient lighting ( page 173).
