Ford 2006 F150 Owner's Manual page 125

Each seating position in your vehicle has a specific safety belt
assembly which is made up of one buckle and one tongue that
are designed to be used as a pair. 1) Use the shoulder belt on the
outside shoulder only. Never wear the shoulder belt under the arm. 2)
Never swing the safety belt around your neck over the inside shoulder.
3) Never use a single belt for more than one person.
While you are fastened in the seat belt, the combination lap/shoulder belt
with a cinch tongue adjusts to your movement. However, if you brake
hard, turn hard, or if your vehicle receives an impact of 8 km/h (5 mph)
or more, the safety belt will become locked and help reduce your
forward movement.
Energy management retractors
Your vehicle has a seat belt system equipped with energy management
retractors at the driver and front outboard passenger seating positions.
An energy management retractor is a device which pays out webbing in a
controlled manner. This feature is designed to help further reduce the
risk of force-related injuries to the occupant.
Seat belt systems equipped with an energy management retractor must
be replaced if they were in use during a frontal collision which resulted
in deployment of the frontal airbags. Refer to the Safety belt
maintenance section in this chapter.
The front and rear safety restraints in the vehicle are combination lap
and shoulder belts. The front passenger outboard and rear outboard seat
safety belts have two types of locking modes described below:
Lap belts
Adjusting the lap belt
The lap belt should fit snugly and as low as possible around the
hips, not across the waist.
The front center lap belt tongue is designed to fit only in the correct
buckle. The tongue will not securely latch if you attempt to use it in any
of the outboard seating position buckles. To ensure that you have used
the correct buckle you should hear a snap and feel it latch.
• Front center lap belt (SuperCab and SuperCrew)
The lap belt does not adjust automatically.
