belts, buckles, latch plates, retractors and anchorages are
working properly. If your vehicle has a built-in child
restraint, also periodically make sure the harness straps,
latch plates, buckle, clip, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt and built-in child restraint system parts. If
you see anything that might keep a safety belt or built-in
child restraint system from doing its job, have
it
repaired. Have any torn or frayed safety belts or harness
straps replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag system
does

“Automitic Transaxle” in the Index.

if needed.
