Chevrolet 2009 Uplander Owner's Manual page 43

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the
driver and right front passenger seating positions.
Adjust the height so that the shoulder portion of the belt is
centered on the shoulder. The belt should be away from
the face and neck, but not falling off of the shoulder.
Improper shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
After the adjuster is set to the desired position, try to
move it down without pushing the button to make sure it
has locked into position.
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.
Safety Belt Pretensioners
This vehicle has safety belt pretensioners for the
front outboard occupants. Although the safety belt
pretensioners cannot be seen, they are part of the safety
belt assembly. They can help tighten the safety belts
during the early stages of a moderate to severe frontal
or near frontal crash if the threshold conditions for
pretensioner activation are met.
Pretensioners work only once. If the pretensioners
activate in a crash, they will need to be replaced, and
probably other new parts for the vehicle's safety
belt system. See Replacing Restraint System Parts
After a Crash on page 1-93.
