(d) Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn or
damaged or that streak or miss areas of the
windshield.
(e) 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.
(f) Lubricate all key lock cylinders, hood latch
assemblies, secondary latches, pivots, spring
anchor and release pawl, hood and door hinges,
rear folding seats, liftgate hinges, fuel door hinge,
power sliding door cable, and sliding door track(s).
More frequent lubrication may be required when
exposed to a corrosive environment. Applying
silicone grease on weatherstrips with a clean
cloth will make them last longer, seal better,
and not stick or squeak.
(g) If you drive regularly under dusty conditions,
inspect the filter at each engine oil change.
(h) Change automatic transaxle fluid and filter if
the vehicle is mainly driven under one or more of
these conditions:
− In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C) or
higher.
− In hilly or mountainous terrain.
− When doing frequent trailer towing.
− Uses such as found in taxi, police, or delivery
service.
(i) Drain, flush, and refill cooling system. See
Engine Coolant on page 430 for what to use.
Inspect hoses. Clean radiator, condenser, pressure
cap, and filler neck. Pressure test the cooling
system and pressure cap.
(j) Check system for interference or binding and
for damaged or missing parts. Replace parts
as needed. Replace any components that have
high effort or excessive wear. Do not lubricate
accelerator or cruise control cables.
(k) A fluid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the fluid level checked. Add fluid
if needed.
