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 5-85.
Spare Tire Check
At least twice a year, after the monthly in ation check of
the spare tire determines that the spare is in ated to the
correct tire in ation 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 ratchet/wheel wrench to
tighten the cable. SeeChanging a Flat Tire on page 5-66.

Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. SeePart D: Recommended Fluids and
Lubricants on page 6-18.
Automatic Transmission Check
Check the transmission uid level; add if needed.
SeeAutomatic Transmission Fluid on page 5-19.
A uid loss may indicate a problem. Check the
system and repair if needed.
At Least Once a Year

speci ed in Part D.

door, rear compartment hinges, latches, locks, hood

release pawl and any moving seat hardware. Part D
tells you what to use. More frequent lubrication may be
required when exposed to a corrosive environment.
