Function of Active Brake Assist
Active Brake Assist consists of:
R
Distance warning function
R
Autonomous braking function
R
Situation-dependent braking assistance
R
Vehicles with Driving Assistance Pack‐
age: Evasive Steering Assist
Active Brake Assist can help you to minimize 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, you will be warned visually and acousti‐
cally.
If you do not react to the visual and audible colli‐
sion warning, autonomous braking can be initi‐
ated in critical situations.
In especially critical situations, Active Brake
Assist can initiate autonomous braking directly.
In this case, the visual and acoustic warning
occurs simultaneously with the braking applica‐
tion.
If you apply the brake yourself in a critical situa‐
tion or apply the brake during autonomous brak‐
ing, situation-dependent braking assistance
occurs. This increases the brake pressure up to
maximum full-stop braking if necessary.
If the autonomous braking function or the situa‐
tion-dependent braking assistance is triggered,
additional preventive measures for occupant
protection (PRE-SAFE
® ) may also be initiated, if
the vehicle is equipped with these.
& WARNING Risk of an accident caused by
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly
identify objects and complex traffic situa‐
tions.
In such cases, Active Brake Assist might:
R
Give a warning or brake without reason
R
Not give a warning or not brake
#
Always pay careful attention to the traf‐
fic situation; do not rely on Active Brake
Assist alone. Active Brake Assist is only
an aid. The driver is responsible for
maintaining a suitable distance to the
vehicle in front, vehicle speed and for
braking in good time.
#
Be prepared to brake or swerve if nec‐
essary.
Also observe the system limitations of Active
Brake Assist.
The individual subfunctions are available in
the following speed ranges:
Distance warning function
The distance warning function issues a warning
at speeds:
R
From approximately 4 mph (7 km/h), if your
vehicle is critically close to a vehicle or
pedestrian. An intermittent warning tone
sounds and the · distance warning lamp
lights up in the instrument cluster.
Brake immediately or take evasive action, provi‐
ded it is safe to do so and the traffic situation
allows this.
