Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses, circuit
breakers and fusible thermal links in the wiring itself.
This greatly reduces the chance
of fires caused by
electrical problems.
Look at the silver-colored band inside the fuse. If
the band is broken or melted, replace the fuse. Be
sure you replace a bad fuse with a new one
of the
identical size and rating.
Instrument Panel Fuse Block
Some fuses are in a fuse
block on the passenger’s
side of the instrument panel.
Pull off the cover labeled
FUSES to expose the fuses.

At Least Twice a Year Automatic Transaxle Check
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. If your vehicle has a built-in child
restraint, also periodically make sure the harness straps,
latch plates, buckle, clip, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt and built-in child restraint system parts. If
you see anything that might keep a safety belt or built-in
child restraint system from doing its
job, have it
repaired. Have any torn or frayed safety belts or harness
straps replaced.
Also look for any opened or broken air bag coverings,
and have them repaired
or replaced. (The air bag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas of the windshield. Also see “Wiper Blades,
Cleaning” in
the Index. Check the transaxle fluid
level; add if needed.
See “Automatic Transaxle” in the Index.
A fluid
loss may indicate a problem. Check the system and
repair if needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified
in Part D.
Body Lubrication Service
Lubricate all hinges and latches including those for the
body doors, hood, rear compartment, glove box door,
console door and any folding seat hardware. Part
D tells
you what to use. More frequent lubrication may be
required when exposed to a corrosive environment.
