X
Brake immediately to increase the distance
from the vehicle in front.
or
X
Take evasive action provided it is safe to do
so.
Due to the nature of the system, certain com-
plex but non-critical driving conditions may also
cause the system to display a warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of approximately 70 km/h, the
distance warning function can also react to sta-
tionary obstacles, such as stopped or parked
vehicles.
Autonomous braking function
If the driver does not react to the distance warn-
ing signal in a critical situation, COLLISION PRE-
VENTION ASSIST PLUS can assist with the
autonomous braking function.
Vehicles without DISTRONIC PLUS: the
autonomous braking function is available in the
following speed ranges:
R
7–105 km/h for moving objects
R
7–50 km/h for stationary objects
Vehicles with DISTRONIC PLUS: the autono-
mous braking function is available in the follow-
ing speed ranges:
R
7–200 km/h for moving objects
R
7–50 km/h for stationary objects
Due to the nature of the system, complex but
non-critical driving conditions may also cause
the autonomous braking function to engage.
If the autonomous braking function demands
particularly high braking force, preventative
passenger protection measures (PRE-SAFE
®
)
are activated simultaneously (

page 57).
Adaptive Brake Assist
General information
i
Observe the "Important safety notes" sec-
tion (
Y
page 67).
With the help of the radar sensor system, Adap-
tive Brake Assist 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 colli-
sion with the vehicle in front, it calculates the
braking force necessary to avoid a collision. If
you apply the brakes forcefully, Adaptive Brake
Assist will automatically increase the braking
force to a level suitable for the traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardous situations at speeds above
7 km/h. It uses the radar sensor system to
assess the traffic situation.
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 obser-
vation.
Up to a speed of approximately 70 km/h, Adap-
tive Brake Assist reacts to stationary obstacles.
If Adaptive Brake Assist demands a particularly
high brake pressure, preventative passenger
protection measures (PRE-SAFE ® ) are activated
simultaneously (
Y
page 57).
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if:
R
you release the brake pedal
R
a danger of collision with the vehicle in front
no longer exists
R
no obstacle is detected in front of your vehicle
Adaptive Brake Assist is then deactivated.
Important safety notes
i
Observe the "Important safety notes" sec-
tion for driving safety systems (
Y
page 67).
G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
R
intervene unnecessarily
R
not intervene
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.
