FORD 2013 F-550 v.3 - Manual (Page 51)

If two adults and a child occupy a Regular Cab, properly restrain the
child in the center front unless doing so would interfere with driving
your vehicle. This provides lap and shoulder belt protection for all
occupants, and airbag protection for the adults. A child or infant
properly restrained in the center front seat should not incur risk of
serious injury from the airbags.
FRONT PASSENGER SENSING SYSTEM
WARNING: Even with Advanced Restraints Systems, children 12
and under should be properly restrained in a rear seating position.
WARNING: The front passenger airbag is not designed to offer
protection to an occupant in the center seating position.
High-series vehicles (if equipped)
The front passenger sensing system
uses a passenger airbag status
indicator that will illuminate,
indicating that the front passenger
frontal airbag is either ON (enabled)
or OFF (disabled). The indicator
lamp is located by the radio.
Note: The passenger airbag status indicator OFF and ON lamps will
illuminate for a short period of time when the ignition is first turned on
to confirm it is functional.
