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 5-86.
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 Changing a
Flat Tire on page 5-71.
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
6-32.
Automatic Transmission Check
Check the transmission fluid level; add if needed.
See
Automatic Transmission Fluid on page 5-25.
A fluid loss may indicate a problem. Check the
system and repair
if needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part D.
Body Lubrication Service

and rear compartment hinges, latches and locks
including interior glove box and console doors, hood
latch assembly, secondary latch, pivots, spring anchor,
release pawl and any moving seat hardware. Lubricate
the hood safety lever pivot and prop rod pivot. Part D
tells you what to use. More frequent lubrication may be
required when exposed
to a corrosive environment.
