Cadillac 2005 XLR Owner's Manual page 55

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 frontal airbags inflate, you will also need to
replace the driver's and passenger's safety belt buckle
assembly. Be sure to do so. Then the new buckle
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 buckle assemblies, even if
the frontal airbags have not deployed. The driver
and front passenger's safety belt buckle 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 3-49.
