Chevrolet 2004 Aveo, Owner'S Manual, Page: 23 / 334

The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you would be less
likely to slide under the lap belt. If you slid under it, the
belt would apply force at your abdomen. This could cause
serious or even fatal injuries. The shoulder belt should go
over the shoulder and across the chest. These parts of
the body are best able to take belt restraining forces.
The safety belt locks if there is a sudden stop or crash,
or if you pull the belt very quickly out of the retractor.
Shoulder Belt Height Adjuster
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 the shoulder belt height adjuster down,
squeeze the release button and move the height
adjuster to the desired position. You can move the
height 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.
