Seating and Safety Restraints 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 Canopyி 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. 184 2004 Expedition (exd) Owners Guide (post-2002-fmt) USA English (fus)
