FORD 2012 F-550 v.3 - Manual (Page 191)

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.
