At Least Twice a Year
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 airbag coverings,
and have them repaired or replaced. (The airbag 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
Windshield, Backglass, and Wiper Blades on page 5-86.
Spare Tire Check
At least twice a year, after the monthly ination check of
the spare tire determines that the spare is inated to
the correct tire ination 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
wrench to tighten the cable. SeeChanging a Flat Tire
on page 5-67.
Weatherstrip Lubrication
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 6-33.
Manual Transmission Check
Check the transmission uid level; add if needed.
SeeManual Transmission Fluid on page 5-22. Check
for leaks. A uid leak is the only reason for uid
loss. Have the system inspected and repaired if needed.
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.
Hydraulic Clutch System Check
Check the uid level in the clutch reservoir.
SeeHydraulic Clutch on page 5-23.
A uid loss in this system could indicate a problem.
Have the system inspected and repaired at once.
