Maintenance Footnotes
(a)Visually inspect brake lines and
hoses for proper hook-up, binding,
leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and rotors
for surface condition. Inspect drum
brake linings/shoes for wear or
cracks. Inspect other brake parts,
including drums, wheel cylinders,
calipers, parking brake, etc.
(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)
Inspect wiper blades for wear,
cracking, or contamination.
Clean the windshield and wiper
blades, if contaminated. Replace
wiper blades that are worn or

(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 Airbag System Check
on page 1-31.
(f)Lubricate all key lock cylinders,
door hinges and latches, hood
hinges and latches and trunk lid
hinges and latches. 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)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.(h)Change automatic transmission
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. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 9-13 for
what to use. Inspect hoses. Clean
radiator, condenser, pressure cap,
and filler neck. Pressure test the
cooling system and pressure cap.(j)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.
(k)If you drive regularly under dusty
conditions, inspect the filter at
each engine oil change.
(l)If you drive regularly under dusty
conditions, the filter may require
replacement more often.
(m)Drain, flush, and refill brake
hydraulic system at a regular service
interval (IorII) every two years.
This service can be complex;
you should have your dealer/retailer
