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 5-84 .

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 folding
wrench to tighten the cable. See Changing a Flat Tire
on page 5-61 .

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 Part D: Recommended Fluids and
Lubricants on page 6-15 .

Automatic Transaxle Check

Check the transaxle fluid level; add if needed. See
Automatic Transaxle Fluid on page 5-18 . A fluid loss
may indicate a problem. Check the system and repair if
needed.
