ANTILOCK BRAKE SYSTEM (ABS)

The concept

The ABS keeps the wheels from locking
while braking, thereby enhancing active
driving safety.

ABS also includes Electronic Brake Force
Distribution (EBD).

Safe braking

Your vehicle is equipped with ABS as a stan-
dard feature. The best way to brake the
vehicle in critical situations requiring brak-
ing is to apply maximum pressure to the
brake pedal: panic stop.
Since the vehicle remains maneuverable,
you can still go around any obstacles with
the smallest possible steering movements.

The pulsation of the brake pedal, together
with the sound of hydraulic regulation,
indicates to you that ABS is actively taking
effect.

Cornering Brake Control (CBC)

Cornering Brake Control (CBC) is an
enhancement of ABS that improves vehicle
stability especially when braking during
cornering.
When the vehicle is being braked, the rear
wheels are relieved from load, and this can
cause the vehicle to oversteer in curves.
CBC counteracts this by making use of uni-
lateral braking pressure to generate a sta-
bilizing counter torque while braking out-
side of the ABS control range.

Electronic Brake Force Distribution
(EBD)

In order to achieve a short braking distance
when the vehicle is fully loaded, your vehi-
cle is equipped with relatively large brakes
on the rear axle. EBV continuously moni-
tors the speeds of the rear wheels in rela-
tion to the front wheels in order to prevent
overbraking of the rear wheels even when
the vehicle has a light load. If the rear
wheels tend to lock, the EBV controls their
slip, ensuring operating stability.
