FORD 2013 F-550 v.3 - Manual (Page 61)

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 frontal or
sideways 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.
• The design of the front airbags is to activate only in frontal and
near-frontal crashes (not rollovers, side impacts or rear impacts)
unless the crash causes sufficient frontal deceleration.
• The design of the safety belt pretensioners is to activate in frontal,
near-frontal and side crashes, and in rollovers.
• The design of the side airbags is to inflate in certain side impact
crashes. Side airbags may activate in other types of crashes if the
vehicle experiences sufficient sideways motion or deformation.
• The design of the Safety Canopy is to inflate in certain side impact
crashes or rollover events. The Safety Canopy may activate in other
types of crashes if the vehicle experiences sufficient sideways motion
or deformation, or a certain likelihood of rollover.
AIRBAG DISPOSAL
Contact your authorized dealer as soon as possible. Airbags MUST BE
disposed of by qualified personnel.
