FORD 2003 F-150 v.3 - Manual (Page 103)

CrewCab base bench seats and all Regular Cab seating positions, the
safety belts are equipped with a retractor pretensioner.
The driver and front outboard passenger safety belt pretensioners are
designed to activate only during certain frontal or near-frontal collisions
with sufficient longitudinal deceleration. A safety belt pretensioner is a
device which tightens the webbing of the lap and shoulder belts during
some collisions in such a way that they fit more snugly against the body.
The driver and front outboard passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the vehicle
is involved in a collision that results in the activation of the safety belt
pretensioners. Refer to the Safety belt maintenance section in this
chapter.
Failure to replace the safety belt assembly under the above
conditions could result in severe personal injuries in the event of
a collision.
Front safety belt height adjustment (if equipped)
If your shoulder belts come out of the front seat back, you will not have
a safety belt height adjuster.
Regular Cab and SuperCab vehicles have safety belt height adjustments
for the driver and front passenger. SuperCrew vehicles have these
adjustments for the driver, front passenger and rear outboard
passengers. Adjust the height of the shoulder belt so the belt rests
across the middle of your shoulder.
