Replacing Restraint System Parts
After
a Crash
If you've had a crash, do you need new safety belts or
built-in child restraint parts?
After a very minor collision, nothing may be necessary.
But if the safety belts or built-in child restraint harness
straps were stretched, as they would be if worn during a
more severe crash, then you need new safety belts or
harness
straps.
If safety belts
or
built-in child restraint harness straps
are cut or darnaged, replace them. Collision damage also
may mean you will need to have safety belt, built-in
child restraint or seat
parts
repaired or replaced.
New
parts and repairs may be necessary even if the safety belt
or built-in child restraint wasn't beine used at the time
of the collision.
If an air bag inflates, you'll need to replace ais bag
system parts. See the part on the air bag system earlier
in this section.
