Braking Assistance Appropriate To The Situation - Mercedes-Benz B-Class Electric Drive Operator's Manual

Function
Starting at a speed of approximately 4 mph
(7 km/h), the distance warning function warns
you if you rapidly approach a vehicle in front. An
intermittent warning tone will then sound, and
the · distance warning lamp will light up in
the instrument cluster.
Brake immediately in order to increase the
X
distance from the vehicle in front.
or
Take evasive action, provided it is safe to do
X
so.
Due to the nature of the system, particularly
complicated 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 44 mph
(70 km/h), the distance warning function can
also react to stationary obstacles, such as stop-
ped or parked vehicles.
Autonomous braking function
If the driver does not react to the distance warn-
ing signal in a critical situation, Active Brake
Assist can assist the driver with the autonomous
braking function.
The autonomous braking function:

The autonomous braking function is available in
the following speed ranges:
4 - 65 mph (7 - 105 km/h) for moving objects

4 - 31 mph (7 - 50 km/h) for stationary

Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause the Autonomous Braking Func-
tion to intervene.

General information

Observe the "Important safety notes" sec-
tion ( page 58).

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
brake pressure necessary to avoid a collision. If
you apply the brakes forcefully, the braking
assistance adapts to the situation and automat-
ically increases the brake pressure to a degree
appropriate to the traffic situation.

Braking assistance appropriate to the situation

provides 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 capa-
ble of reacting to moving objects that have
already been recognized as such at least once
over the period of observation, up to vehicle
speeds of around 155 mph (250 km/h).
Braking assistance appropriate to the situation
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.
Braking assistance appropriate to the situation
is then deactivated.
