When braking in the ABS control range, the vehicle is

In exceptional situations, it may be advantageous to

– on loose ground.
– in deep snow
O
– when "rocking the vehicle free".

ABS brake system (anti-lock
braking system)
Loss of control over the
WARNING
vehicle
The ABS cannot reduce the risk of accidents due to
inappropriate speed.
The increased safety that is provided should not in-
duce you to take greater risks with your safety. The
laws of physics for driving cannot be overridden even
with ABS.
e Despite ABS, drivers remain responsible for
adapting their driving style and maneuvers to the
road and weather conditions, as well as the traf-
fic situation.
Operating principle
The anti-lock braking system (ABS) prevents the
wheels from locking during full braking. This ensures
that the vehicle has enhanced driving stability and
maneuverability in hazardous situations.
ABS begins to take control as soon as one wheel
shows a tendency to lock.
The controlled braking process is comparable to ca-
dence braking in very rapid succession. The driver is
warned to adapt the driving speed to the road con-
ditions by a pulsing brake pedal and a "juddering
noise".
Carrying out full braking with ABS
If full braking is necessary:
e Fully depress the brake pedal during the entire
braking operation, despite the pulsing pedal. Do
not reduce the braking pressure.
Multi-collision braking
During an accident, multi-collision braking can help
the driver reduce the risk of skidding and further
collisions during the accident through automatically
initiated braking.
Prerequisites
Multi-collision braking only happens:
– during front, side and rear-end collisions
– when the airbag control unit detects an appro-
priate activation threshold during an accident
– during an accident at a driving speed above ap-
prox. 5 mph (10 km/h)
Information
The vehicle is decelerated automatically by the PSM
system, provided the hydraulic brake system, PSM,
and electrical system remain undamaged and op-
erational during the accident.
Exceptions
The following activities prevent automatic braking in
the event of an accident:
– The driver depresses the accelerator pedal a sig-
nificant amount.
– The braking pressure exerted by the driver on the
brake pedal is stronger than the brake pressure
applied by the system.
