Restraint System Check
Make sure the safety belt reminder light and all your
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,

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
not need regular maintenance.)

inserts that appear worn or damaged or that streak or
miss areas
