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 other brake parts, including
calipers, parking brake, etc.
(b)Visually inspect front and rear
suspension and steering system for
damaged, loose, or missing parts
or signs of wear.
(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
damaged. See Windshield Wiper
Blade Replacement on page 5-38
and Windshield and Wiper
Blades on page 5-71 for more
information.
(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 1-56.
(f)Lubricate all key lock cylinders,
door hinges and latches, hood
hinges and latches, glove box
hinges, sunroof (if equipped), and
any folding seat hardware. More
frequent lubrication may be required
when exposed to a corrosiveenvironment. Applying silicone
grease on weatherstrips with a clean
cloth will make them last longer,
seal better, and not stick or squeak.
(g)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.
(h)Severe service is when 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.

When doing frequent trailer
towing.
