Pontiac 2005 Vibe - Manual (Page 26)

To unlatch the belt, just push the button on the buckle.
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. 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 down, squeeze
the button 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 squeezing the release button
to make sure it has locked into position.
