FORD 2013 F-550 v.1 - Manual (Page 60)

• The readiness light will either flash or stay lit.
• The readiness light will not illuminate immediately after the
ignition is turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem or light are repaired.
If any of these things happen, even intermittently, have the supplemental
restraint system serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a crash.
The safety belt pretensioners and the airbag supplemental restraint
system are designed to activate when the vehicle sustains longitudinal or
lateral deceleration sufficient to cause the restraints control module to
deploy a safety device or when a certain likelihood of a rollover event is
detected by the rollover sensor.
The fact that the safety belt pretensioners or airbags did not activate for
both front seat occupants in a crash does not mean that something is
wrong with the system. Rather, it means the restraints control module
determined the accident conditions (such as crash severity, belt usage)
were not appropriate to activate these safety devices.
• Front airbags are designed to activate only in frontal and near-frontal
crashes (not rollovers, side impacts or rear impacts) unless the crash
causes sufficient longitudinal deceleration.
• The safety belt pretensioners are designed to activate in frontal,
near-frontal and side crashes, and in rollovers.
• Side airbags are designed to inflate in side-impact crashes, not
rollovers, rear impacts, frontal or near-frontal crashes, unless the crash
causes sufficient lateral deceleration.
• The Safety Canopy is designed to inflate in certain side impact crashes
or rollover events, not in rear impact, frontal or near-frontal crashes,
unless the crash causes sufficient lateral deceleration or rollover
likelihood.
AIRBAG DISPOSAL
Contact your authorized dealer as soon as possible. Airbags MUST BE
disposed of by qualified personnel.
