FORD 2004 Expedition v.3 - Manual (Page 184)

The RCM (restraints control module) monitors its own internal circuits
and the supplemental air bag electrical system wiring (including the
impact sensors, the system wiring, the air bag system readiness light, the
air bag back up power and the air bag ignitors).
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to Air bag readiness section
in the Instrument Cluster chapter. Routine maintenance of the air bag is
not required.
A difficulty with the system is indicated by one or more of the following:
• The readiness light will either
flash or stay lit.
• The readiness light will not
illuminate immediately after ignition is turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced at
your dealership or by a qualified technician immediately. Unless serviced,
the system may not function properly in the event of a collision.
Safety Canopy ி system (if equipped)
Do not place objects or
mount equipment on or
near the headliner at the siderail
that may come into contact with a
deploying Safety Canopy
௢. Failure
to follow these instructions may
increase the risk of personal injury
in the event of a collision.
Do not lean your head on the door. The Safety Canopy
௢ could
injure you as it deploys from the headliner.
Do not attempt to service, repair, or modify the Safety Canopy
௢
system, its fuses, the A, B, or C pillar trim, or the headliner on a
vehicle containing a Safety Canopy
௢. See your Ford or Lincoln
Mercury dealer.
