With the help of the radar sensor system,
Active Brake Assist can detect obstacles that
are in the path of your vehicle for an extended
period of time.
If Active Brake Assist detects a risk of collision
with the vehicle in front, it calculates the brake
pressure necessary to avoid a collision. If you
apply the brakes forcefully, situation-depend-
ent braking assistance adapts to the situation
and automatically increases the brake pres-
sure to a degree appropriate to the traffic sit-
uation.
Situation-dependent braking assistance pro-
vides braking assistance in hazardous situa-
tions at speeds above 4 mph (7 km/h). It uses
radar sensor technology to assess the traffic
situation.
Situation-dependent braking assistance is
capable of reacting to moving objects that
have already been detected as such at least
once over the period of observation, up to
vehicle speeds of around 155 mph
(250 km/h).
Situation-dependent braking assistance can
also detect stationary objects, up to vehicle
speeds of around 44 mph (70 km/h).
Keep the brake pedal depressed until the
X
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if:
you release the brake pedal
R
there is no longer any danger of a collision
R
no obstacle is detected in front of your vehi-
R
cle
Situation-dependent braking assistance is then
deactivated.
Important safety notes
i
Observe the "Important safety notes" sec-
tion for driving safety systems (
G
Active Brake Assist does not react:
to persons, bicycles, motorcycles or ani-
R
mals
to approaching vehicles
R
to cross traffic
R
on bends
R
As a result, Active Brake Assist cannot inter-
vene in all critical situations. There is a risk
of an accident.
Always pay careful attention to the traffic
situation and be prepared to brake.
G
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist might:
intervene unnecessarily
R
not intervene
R
There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. Terminate
the intervention in a non-critical driving sit-
uation.
Due to the nature of the system, complex but
non-critical driving conditions may also cause
Active Brake Assist to intervene.
Even if Active Brake Assist is not available due
to a malfunction in the radar sensor system,
the brake system is still available with full
brake boosting effect and BAS.
