Buick 2006 Rainier Maintenance Manual page 69

If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the
belt or LATCH system was not being used at the time
of the collision.
If an airbag inflates, you will need to replace airbag
system parts. See the part on the airbag system
earlier in this section.
If the airbags inflate you will also need to replace the
driver and front passenger's safety belt retractor
assembly. Be sure to do so. Then the new retractor
assembly will be there to help protect you in a collision.
After a crash you may need to replace the driver and
front passenger's safety belt retractor assemblies,
even if the airbags have not deployed. The driver
and 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 3-29.
