Vehicles with DISTRONIC PLUS: the auton-

omous braking function is available in the fol-

lowing speed ranges:

R

5 - 124 mph (7 - 200 km/h) for moving

objects

R

5 - 31 mph (7 - 50 km/h) for stationary

objects

If the autonomous braking function requires a

particularly high braking force, preventative

passenger protection measures (PRE-SAFE

®

)

are activated simultaneously.

Adaptive Brake Assist

i

Observe the "Important safety notes" sec-

tion (Y page 71).

Adaptive Brake Assist provides braking assis-

tance in hazardous situations at speeds

above 4 mph (7 km/h). It uses radar sensor

technology 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:

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.

G

WARNING

Adaptive Brake Assist does not react:

R

to people or animals

R

to oncoming vehicles

R

to crossing traffic

R

when cornering

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.

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

there is no longer any danger of a collision.

R

no obstacle is detected in front of your

vehicle.

Adaptive Brake Assist is then deactivated.

If adaptive Brake Assist demands particularly

high braking force, preventative passenger

protection measures (PRE-SAFE

®

) are activa-

ted simultaneously.

Up to a speed of approximately 155 mph

(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 44 mph

(70 km/h), adaptive Brake Assist reacts to

stationary obstacles.
