Driving safety systems

The autonomous braking function is available
in the following speed ranges:
from 7 km/h to approx. 105 km/h for mov-
R
ing objects
from 7 km/h to approx. 50 km/h for sta-
R
tionary objects
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 77).
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-
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
detected 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.
