Seating and Safety Restraints WARNING: If the Safety Canopy system has deployed, the Safety Canopy will not function again unless replaced. The Safety Canopy system (including the A, B, C, and D pillar trim and headliner) must be inspected and serviced by an authorized dealer. If the Safety Canopy is not replaced, it will not function again, which will increase the risk of injury in a future collision. 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 Warning lights and chimes in the Instrument Cluster chapter. Routine maintenance of the side airbag is not required. A difficulty with the system is indicated by one or more of the following: • The readiness light (same light as for front airbag system) 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 authorized dealer immediately. Unless serviced, the system may not function properly in the event of a collision. SOS Post-Crash Alert System™ The system automatically flashes the turn signal lamps and sounds the horn three times at four second intervals in the event of a serious impact that deploys an airbag (front, side, side curtain [if equipped] or Safety Canopy௡ [if equipped]) or the safety belt pretensioners. The system can be turned off when any one of the following actions are taken by the driver or any other person: • pressing the hazard control button, • or pressing the panic button on the remote entry transmitter. The feature will continue to operate until the vehicle runs out of power. 187 2011 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
