4WABS warning light

The 4WABS computer continuously
monitors the system while driving for
any electrical or system malfunctions.

In addition, the 4WABS computer per-
forms an initial system check called
bulb proveout when the vehicle ignition
is switched on. During bulb proveout,
the amber ‘‘ABS’’ light on the instru-
ment cluster will momentarily illumi-
nate and then go out.

NOTE

After staring the vehicle and upon ini-
tial drive-off, the driver may notice a
single pulse of the brake pedal and a
noise from the engine compartment.
This is part of the initial system check
and is normal.

The ABS warning light 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 anti-
lock brake system is disabled and normal
braking is still effective unless the brake
warning light also remains illuminated
with parking brake released. (If your

brake warning light illuminates, have
your vehicle serviced immediately.)

NOTE

Mobile phones or radio transmitters
not installed by Mazda Motor Corpo-
ration may interfere with the antilock
brake system. Should the antilock sys-
tem activate unexpectedly or the ABS
light illuminate after installation of
such a unit, have the installation of the
unit checked.
