GMC 2003 Sonoma Owner's Manual page 73

If you've had a crash, do you need new belts or LATCH
system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if
worn during a more severe crash, then you need
new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
If you ever see a label on
the driver's or the right
front passenger's safety
belt that says to replace
the belt, be sure to do so.
Then the new belt will
be there to help protect
you in a collision. You
would see this label on the
belt near the door
opening.
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 wasn't being used at the time of
the collision.
If an air bag inflates, you'll need to replace air bag
systems parts. See the part on the air bag system earlier
in this section.
