door utility models and the second seat of
Suburbans have shoulder belt height adjusters. Move the
shoulder belt height adjuster to the height that is right
for you.
To move the height adjuster down, push in at the word
PRESS 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 pushing in 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.
CAUTION:
You can be seriously hurt if your shoulder belt is
too loose. In a crash, you would move forward
too much, which could increase injury. The
shoulder belt should fit against your body.
