GMC Jimmy 2004 Owner's Manual page 66

If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
1-60
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.
