Tone Generator - Ford Vehicle Owner's Manual

The air bag system uses a readiness light and a
tone to indicate the condition of the system. The
readiness light is in the instrument cluster. When
you turn the ignition to the ON position, this
light will illuminate for approximately six (6)
seconds and then turn off. This indicates that the
system is operating normally. NOTE:
Maintenance of the air bag system is not
required.
A problem with the system is indicated by one
or more of the following: the readiness light will
either flash or stay lit, or it will not light, or a
group of five beeps will be heard.
If any of these things happen, even
intermittently, have the air bag system
serviced at your Ford or Lincoln-Mercury
dealer immediately.

The air bag readiness light indicates the air bag
system condition. However, a series of five sets
of five beeps will be heard only if the readiness
light does not work and there is a problem with
the air bag system. This also means that the Air
Bag Supplemental Restraint System (SRS) is in
need of service. The tone pattern will repeat
(five sets of five beeps) periodically until the
problem and light are repaired. Unless serviced,
the Air Bag Supplemental Restraint System may
not function properly in the event of a collision.
Do not attempt to service, repair, or
modify the Air Bag Supplemental
Restraint System or its fuses. See your
Ford or Lincoln-Mercury dealer.
