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.
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 wrench
to tighten the cable. See "Storing the Spare Tire and
Tools" in the Index.
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. See "Recommended Fluids and Lubricants"
in the Index.
Automatic Transmission Check
Check the transmission fluid level; add if needed.
See "Automatic Transmission Fluid" in the Index.
A fluid loss may indicate a problem. Check the
system and repair if needed.
