FORD 2013 F-550 v.2 - Manual (Page 60)

Children 12 years old and under should always be properly restrained
in the rear seats. The Safety Canopy will not interfere with children
restrained using a properly installed child or booster seat because it is
designed to inflate downward from the headliner above the doors along
the side window opening.
The design and development of the Safety Canopy included recommended
testing procedures that were developed by a group of automotive safety
experts known as the Side Airbag Technical Working Group. These
recommended testing procedures help reduce the risk of injuries related
to the deployment of side airbags (including the Safety Canopy).
CRASH SENSORS AND AIRBAG INDICATOR
WARNING: Modifying or adding equipment to the front end of
your vehicle (including frame, bumper, front end body structure
and tow hooks) may affect the performance of the airbag system,
increasing the risk of injury. Do not modify the front end of your vehicle.
Your vehicle has a collection of crash and occupant sensors which
provide information to the restraints control module which deploys
(activates) the front safety belt pretensioners, driver airbag, passenger
airbag, seat mounted side airbags, and the Safety Canopy. Based on the
type of accident (frontal impact, side impact or rollover) the restraints
control module will deploy the appropriate safety devices.
The restraints control module also monitors the readiness of the above
safety devices plus the crash and occupant sensors. The readiness of the
safety system is indicated by a warning indicator light in the instrument
cluster or by a backup tone if the warning light is not working. See the
Instrument Cluster chapter. Routine maintenance of the airbag is not
required.
A difficulty with the system is indicated by one or more of the following:
• 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.
