Chevrolet Aveo 2007 Owner's Manual page 86

If an airbag inflates, you will need to replace
airbag system parts. See the part about the airbag
system earlier in this section.
If the frontal airbags inflate, you will also need to
replace the driver's and right front passenger's
safety belt pretensioners and safety belt. Be sure
to do so. Then the new pretensioner and safety
belt will be there to help protect you in a collision.

After a crash you may need to replace the driver
and right front passenger's safety belt retractor
assemblies, even if the frontal airbags have
not deployed. The driver and right front
passenger's safety belt retractor assemblies
contain the safety belt pretensioners. Have your
safety belt pretensioners checked if your
vehicle has been in a collision, or if your airbag
readiness light stays on after you start your vehicle
or while you are driving. See Airbag Readiness
Light on page 176.
