Anti-lock Brake System (ABS
ABS continually monitors the brake system
and prevents the wheels from locking
reg ardless of the type of road surfac e or
tyre grip.
It starts to regulate the braking p ressure as
soon as a w heel shows a tendency to lock.
The v ehicle remains steera ble, even in the
event of very heavy braking, for instance
on bends or when sw erving to av oid an
obstacle. Even in the ca se of full-on
braking, the ABS makes it p ossible to drive
round an obsta cle without releasing the
brakes.
ABS control is made app arent through a
pulse in the brake peda l and the noise of
the regulation proc ess.
