CHEVROLET 2010 Silverado - Manual (Page 75)

Regular and Crew Cab
To move the adjuster
down for the regular and
crew cabs, squeeze the
buttons (A) on the sides of
the height adjuster and
move the height adjuster
to the desired position.
Extended Cab
On the extended cab,
push down on the release
button (A) 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 buttons for the
regular and crew cabs, or without pushing the release
button for extended cabs, to make sure it has locked
into position.
