Mercedes-Benz C-Class 2014 Owner's Manual page 82

Vehicles with DISTRONIC PLUS: the auton-
omous braking function is available in the fol-
lowing speed ranges:
7 - 200 km/h for moving objects
R
7 - 50 km/h for stationary objects
R
If the autonomous braking function demands
particularly high braking force, preventative
passenger protection measures (PRE-SAFE
are activated simultaneously.
Adaptive Brake Assist
i
Observe the "Important safety notes" sec-
tion ( page 74).
Y
Adaptive Brake Assist provides braking assis-
tance in hazardous situations at speeds
above 7 km/h. It uses radar sensor technol-
ogy to assess the traffic situation.
G WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
intervene unnecessarily
R
not intervene
R
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
G WARNING
Adaptive Brake Assist does not react:
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
R
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
Due to the nature of the system, particularly
complicated but non-critical driving condi-
Driving safety systems
tions may also cause Brake Assist to inter-
vene.
If adaptive Brake Assist is not available due to
a malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.
With the help of adaptive Brake Assist, the
distance warning signal can detect obstacles
®
)
that are in the path of your vehicle for an
extended period of time.
If adaptive Brake Assist detects a risk of col-
lision with the vehicle in front, it calculates
the braking force necessary to avoid a colli-
sion. If you apply the brakes forcefully, adap-
tive Brake Assist will automatically increase
the braking force to a level suitable for the
traffic conditions.
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
R
vehicle
Adaptive Brake Assist is then deactivated.
If adaptive Brake Assist demands particularly
high braking force, preventative passenger
protection measures (PRE-SAFE
ted simultaneously.
Up to a speed of approximately 250 km/h,
adaptive Brake Assist is capable of reacting to
moving objects that have already been detec-
ted as such at least once over the period of
observation.
Up to a speed of approximately 70 km/h
adaptive Brake Assist reacts to stationary
obstacles.
