Installing Latch Seats - Ford 2004 F150 Owner's Manual

Seating and Safety Restraints
Installing LATCH seats (Regular Cab)
When you install a child seat on the front passenger seat of a
Regular Cab, turn the Passenger Airbag On/Off switch to OFF.
If you tightly install a LATCH infant or child safety seat with its own
webbing-mounted attachments to the LATCH anchors on the front
passenger seat of the Regular Cab, the front passenger sensing system
may not automatically turn the airbag off. The vehicle safety belts at the
right front seat include a sensor that adjusts the weight on the seat
cushion. This adjustment does not work when the child seat is installed
using the LATCH attachment belts instead of the vehicle safety belts.
Therefore, turn the airbag OFF with the manual Airbag On/Off switch.
