Pontiac 2004 GTO - Manual (Page 20)

The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this
applies force to the strong pelvic bones. And you would
be less likely to slide under the lap belt. If you slid
under it, the belt would apply force at your abdomen.
This could cause serious or even fatal injuries. The
shoulder belt should go over the shoulder and across
the chest. These parts of the body are best able to take
belt restraining forces.
The safety belt locks if there is a sudden stop or a
crash, or if you pull the belt very quickly out of
the retractor.
Shoulder Belt Height Adjuster
Before you begin to drive, move the shoulder belt height
adjuster to the height that is right for you.
Adjust the height so that the shoulder portion of the belt
is centered on your shoulder. The belt should be
away from your face and neck, but not falling off your
shoulder.
To move it up or down,
squeeze the adjuster as
shown and move it to
the desired position. After
you move the adjuster
to where you want it, try to
move it without squeezing
it, to make sure it has
locked into position.
