Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts.
If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
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.)
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
Cleaning the Outside of Your Vehicle on page 5-88.
Spare Tire Check
At least twice a year, after the monthly inflation check of
the spare tire determines that the spare is inflated to
the correct tire inflation pressure, make sure that
the spare tire is stored securely. Push, pull, and then try
to rotate or turn the tire. If it moves, use the wheel
wrenchhatchet to tighten the cable. See
Changing a Flat
Tire on page 5-69.

Automatic Transmission Fluid on page 5-27. A fluid loss
may indicate a problem. Check the system and repair
if needed.
