Active Brake Assist

General information
i
Observe the "Important safety notes" sec-
tion ( page 58).
Y
Active Brake Assist consists of a distance warn-
ing function with an autonomous braking func-
tion and braking assistance appropriate to the
situation.
Active Brake Assist can help you to minimize the
risk of a collision with the vehicle traveling in
front or reduce the effects of such a collision.
If Active Brake Assist detects that there is a risk
of collision, you will be warned visually and
acoustically. If you do not react to the visual and
audible collision warning, autonomous braking
can be initiated in critical situations. If you apply
the brake yourself in a critical situation, Adap-
tive Brake Assist supports you with braking
assistance appropriate to the situation.
Important safety notes
Detection of hazardous situations can be par-
ticularly impaired by:
there is dirt on the sensors or anything else
R
covering the sensors
there is snow or heavy rain
R
there is interference by other radar sources
R
there are strong radar reflections, for exam-

on the Active Brake Assist system
Observe the important safety notes in the
"Breaking-in notes" section (
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at low
speeds where no visible damage to the front of
the vehicle is apparent.
Activating/deactivating
Active Brake Assist is active after every ignition
cycle.
You can activate or deactivate Active Brake
Assist ( page 162) in the on-board computer.
Y
When deactivated, the distance warning func-
tion and the autonomous braking function are
also deactivated.
If Active Brake Assist is deactivated, the æ
symbol appears in the assistance graphic dis-
play.
Distance warning function
General information
The distance warning function can help you to
minimize the risk of a front-end collision with a
vehicle ahead or reduce the effects of such a
collision. If the distance warning function
detects that there is a risk of a collision, you will
be warned visually and acoustically.
