leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and rotors
for surface condition. Inspect other
brake parts, including calipers,
parking brake, etc. Check parking
brake adjustment.
(b) Visually inspect front and rear
suspension and steering system for
damaged, loose, or missing parts or
signs of wear. Inspect power steering
lines and hoses for proper hook-up,
binding, leaks, cracks, chafing, etc. (c)
Visually inspect hoses and have
them replaced if they are cracked,
swollen, or deteriorated. Inspect all
pipes, fittings and clamps; replace
with genuine parts as needed.
To help ensure proper operation,
a pressure test of the cooling system
and pressure cap and cleaning
the outside of the radiator and
air conditioning condenser is
recommended at least once a year. (d)

(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

page 1-61.

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.

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

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.

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.
