(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 1-61.

hood latch assemblies, secondary
latches, pivots, spring anchor and
release pawl, hood and door hinges,
rear folding seats, and liftgate

silicone grease on weatherstrips with
a clean cloth will make them last
longer, seal better, and not stick or
squeak.

system could indicate a problem.

and repaired and the fluid level
checked. Add fluid if needed.(h)Change automatic transmission

When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.

system. This service can be
complex; you should have your
dealer/retailer perform this service.

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 havehigh 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
