Pontiac 2005 Grand Prix - Manual (Page 28)

To unlatch the belt, just push the button on the buckle.
The tension reducer will release and the belt should
go back out of the way.
Before you close the door, be sure the belt is out of
the way. If you slam the door on it, you can damage
both the belt and your vehicle.
Shoulder Belt Height Adjustment
Before you begin to drive, move the shoulder belt
adjuster to the height that is right for you.
To move it down, pull the
release button out 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.
