pretensioner. Do NOT place objects between the seats, this could
interfere with the functioning of the pretensioner. For the SuperCab and
CrewCab base bench seats and all Regular Cab seating positions, the
safetybelts are equipped with a retractor pretensioner.
The safetybelt pretensioners are designed to activate onlyduring certain
frontal or near-frontal collisions with sufficient longitudinal deceleration.
A safetybelt pretensioner is a device which tightens the webbing of the
lap and shoulder belts during some collisions in such a waythat theyfit
more snuglyagainst the body.
The driver and front outboard passenger safetybelt 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 safetybelt
pretensioners. Refer to the Safety belt maintenance section in this
chapter.
Failure to replace the safetybelt assemblyunder the above
conditions could result in severe personal injuries in the event of
a collision.
Front safety belt height adjustment
If your shoulder belts come out of the seatback, you will not have a
safetybelt height adjuster.
Adjust the height of the shoulder belt so the belt rests across the middle
of your shoulder.
