Pontiac 2004 Grand Prix - Manual (Page 23)

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’d 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’s a sudden stop or 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
adjuster to the height that is right for you.
To mve it down, pull
the release button out
as shown and move
the height adjuster to
the desired position.
You can move the adjuster up just by pushing up on
the shoulder belt guide. After you move the adjuster to
where you want it, try to move it down without pulling
the release button to make sure it has locked into
position.
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.
