FORD 2004 F-150 v.3 - Manual (Page 126)

The front passenger sensing system is designed to turn off the front
passenger’s frontal air bag when a rear facing child seat, a forward-facing
child restraint, or a booster seat is detected. If the child restraint has
been installed and the indicator is not lit, then turn the vehicle off,
remove the child restraint from the vehicle and reinstall the restraint
following the child restraint manufacturer’s directions. The system may
not automatically turn the airbag OFF if a child seat is attached to the
LATCH anchors on the front passenger seat of the Regular Cab,
therefore turn the airbag OFF with the manual Airbag On/Off switch.
The front passenger sensing system is designed to enable (may inflate)
the right front passenger’s frontal air bag anytime the system senses that
a person of adult size is sitting properly in the front passenger seat.
When the passenger sensing system has allowed the air bag to be
enabled, the indicator will be unlit and stay unlit to remind you that the
air bag is enabled (may inflate).
If a person of adult-size is sitting in the front passenger’s seat, but the
“passenger air bag off” or “pass air bag off” indicator is lit, it could be
that the person isn’t sitting properly in the seat. If this happens, turn the
vehicle off and ask the person to place the seatback in the full upright
position, then sit upright in the seat, centered on the seat cushion, with
the person’s legs comfortably extended. Restart the vehicle and have the
person remain in this position for about two minutes. This will allow the
system to detect that person and then enable the passenger’s air bag. If
the indicator lamp remains lit even after this, then the occupant should
be advised to ride in the back seat.
After all occupants have adjusted their seats and put on seat belts, it’s
very important that they continue to sit upright, with their back against
the seatback, with their feet comfortably extended on the floor while the
vehicle is still in motion. Sitting improperly can increase the chance of
injury in a crash event. For example, if an occupant slouches, lies down,
turns sideways, sits forward, leans forward or sideways, or puts one or
both feet up, the chance of injury during a crash is greatly increased.
Sitting improperly out of position or with the seatback reclined
too far can take off weight from the seat cushion and affect the
decision of the passenger sensing system, resulting in serious injury or
death in a crash.
Always sit upright against your seatback, with your feet on the floor.
