Chevrolet 2004 Aveo Owner's Manual page 33

To learn how to use the safety belt once it is installed,
see "Lap-Shoulder Belt" under Rear Seat Passengers on
page 1-23. The installed safety belt works the same
way as the safety belt in the rear outside seat positions.
3. Insert the upper part of
the safety belt into the
safety belt guide.
Make sure the safety
belt is not twisted.
Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the driver
and right front passenger. They help the safety belts
reduce a person's forward movement in a moderate
to severe crash in which the front of the vehicle
hits something.
Pretensioners work only once. If they activate in a
crash, you'll need to get new ones, and probably other
new parts for your safety belt system. See Replacing
Restraint System Parts After a Crash on page 1-59.
