FORD 2002 F-550 v.3 - Manual (Page 12)

Brake system warning
To confirm the brake system warning
light is functional, it will momentarily
illuminate when the ignition is
turned to the ON position
(alternatively for some vehicles when the ignition is moved from the ON
position to START position, the light will momentarily illuminate prior to
reaching the START position). It also illuminates if the parking brake is
engaged. If the brake system warning light does not illuminate as
described, seek service immediately. Illumination after the parking brake is
released indicates low brake fluid level or a brake system malfunction and
the brake system should be serviced immediately by a qualified technician.
Refer to Brakes in the Driving chapter for more information.
Anti-lock brake system (ABS)
To confirm the anti-lock brake
system (ABS) warning light is
functional it will momentarily
illuminate when the ignition is
turned to the ON position (alter-
natively for some vehicles when the ignition is moved from the ON
position to the START position, the light will momentarily illuminate just
prior to reaching the START position). If the light remains on, continues
to flash or fails to illuminate, have the ABS serviced immediately. If the
ABS light remains on, it means the anti-lock brake system has malfunc-
tioned and is disabled, however, the normal brake system will still function
unless the brake warning light also remains illuminated and parking brake
is off. Refer to Brakes in the Driving chapter for more information.
Safety belt
Illuminates to remind you to fasten
your safety belts. For more
information, refer to the Seating
and safety restraints chapter.
Air bag readiness
Illuminates to confirm that the air
bags (front or side) are operational.
If the light fails to illuminate,
continues to flash or remains on,
have the system serviced immediately.
