Anti-lock Brake System ABS

The principle

ABS prevents the wheels from locking
when the brakes are applied, and thus
increases active safety.

Braking with ABS

You use ABS most effectively by apply-
ing maximum brake pressure in situa-
tions which call for this – full braking.
Since the car remains steerable, you
can avoid obstacles by turning the
steering wheel as smoothly as possible.

The brake pedal pulsates and the noise
of the hydraulic control system is audi-
ble, warning the driver that the ABS is
active.

Dynamic Brake Control DBC

DSC incorporates the DBC functional-
ity, see page

When you apply the brakes rapidly this
system automatically ensures maximum
brake-servo boost, thus helping mini-
mise braking distance in an emergency.
The advantages of ABS are also uti-
lised.

While braking is in progress, do not
reduce the pressure applied to the
brake pedal. DBC is deactivated when
you release the brake pedal.

Cornering Brake Control CBC

CBC is a development based on ABS.
When the brakes are applied on a cor-
ner when lateral acceleration is high, or
during a lane change, it further
improves the car's stability and makes it
easier to steer.
