(e) Make sure the safety belt
reminder light and safety belt
assemblies 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 see
Checking the Restraint Systems
on page 1-59.
(f) Lubricate all key lock cylinders,
hood latch assemblies, secondary
latches, pivots, spring anchor and
release pawl, hood and door hinges,
rear folding seats, and liftgate
hinges. 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) 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.
(h) Change automatic transmission
fluid 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. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 5-17 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) Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.
(l) If driving regularly under dusty
conditions, inspect the filter at each
engine oil change.
(m) Change transfer case fluid 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.
