FORD 2002 Focus v.2 - Manual (Page 187)

Driving
187
The ABS continuously monitors all
four wheel speeds and detects the
onset of wheel lockup during brake
applications and, if required,
modulates brake pressure to
individual wheels to maintain
braking at optimum efficiency and
ensure that steering control is not
adversely affected. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during
hard braking with loss of front
braking traction.
ABS warning lamp
(if equipped)
The ABS warning lamp in the
instrument cluster momentarily
illuminates when the ignition is
turned on and the engine is off. If
the light does not illuminate
momentarily at start up, remains on
or continues to flash, the ABS
needs to be serviced. With the ABS
light on, the antiĆlock brake system
is disabled and normal braking is
still effective unless the brake
warning light also remains
illuminated with parking brake
released.
If the ABS and/or brake warning
lights illuminate when the engine is
on and the parking brake is in the
fully off position, have your vehicle
serviced immediately.
