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,
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 covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn
or damaged or that streak or
miss areas of the windshield. Also see “Wiper Blades,
Cleaning” in the Index. Check
the transmission fluid
level; add if needed. See
“Automatic Transmission’’ in the Index.
A fluid loss
may indicate a problem. Check the system and repair
if needed.
At Least Once a Year
Key Lock Cylinders Service
