6-56 Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood electrical center. An electrical overload
will cause the lamps to go on and off, or in some cases
to remain off. If this happens, have your headlamp
system checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, have
it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed.
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.
Additional fuses are in the underhood electrical
centers on the driver's and passenger's sides of the
engine compartment.

Restraint System Check
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 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 ªWiper Blades,
Cleaningº in the Index.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply silicone
grease with a clean cloth. During very cold, damp weather
more frequent application may be required. (See
ªRecommended Fluids and Lubricantsº in the Index.)Automatic Transaxle Check
Check the transaxle fluid level; add if needed. See
ªAutomatic Transaxle Fluidº 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, secondary latch, pivots, spring
anchor, release pawl, rear compartment, glove box door
and the console door. Part D tells you what to use. More
frequent lubrication may be required when exposed to a
corrosive environment.
