Buick 2006 Rendezvous - Manual (Page 41)

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
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 down, push
down on the button (A)
and move the height
adjuster to the desired
position. You can move
the height adjuster
up by pushing up on
the shoulder belt guide.
After you move the height adjuster to where you want
it, try to move it down without pushing the button
down to make sure it has locked into position.
