Maintenance Footnotes
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang,
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

parts or signs of wear. Inspect power steering lines
and hoses for proper hook-up, binding, leaks,
cracks, chang, etc.
469

(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings 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 400and
Windshield and Wiper Blades on page 445for
more information.
(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages 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
look for any opened or broken airbag coverings,
and have them repaired or replaced. The
airbag system does not need regular maintenance.(f)Lubricate all key lock cylinders. Lubricate all
hinges and latches, including those for the hood,
rear compartment, glove box door, and console
door. 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)If you drive regularly under dusty conditions,
the lter may require replacement more often.
(h)Change automatic transmission uid and lter
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.
Professional vehicle uses, such as limousine
service.
Uses such as high performance operation.
