Seating and Safety Restraints 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 the Airbag readiness section in the Instrument Cluster chapter. Routine maintenance of the airbag is not required. Any 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 light are repaired. If any of these things happen, even intermittently, contact your authorized dealer as soon as possible. Unless serviced, the system may not function properly in the event of a collision or rollover event. 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 or Safety Canopy௡) 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. Disposal of airbags and airbag equipped vehicles (including pretensioners) Contact your authorized dealer as soon as possible. Airbags MUST BE disposed of by qualified personnel. 182 2011 Expedition (exd) Owners Guide, 1st Printing USA (fus)
