3. Attach the folding
wrench to the jack,
and turn the wrench
clockwise to raise
the jack head a
few inches.
4. Raise the vehicle by turning the folding wrench
clockwise in the jack. Raise the vehicle far enough
off the ground so there is enough room for the
compact spare tire to
fit under the wheel well.
5. Remove all the wheel nuts and take off the flat tire.
6. Remove any rust or dirt
from the wheel bolts, mounting surfaces
and spare wheel.
Rust or dirt on the wheel, or on the parts to
which
it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come
off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches
to the
vehicle.
In an emergency, you can use a cloth
or a paper towel to do this;
but be sure to use
a scraper or wire brush later, if you need to,
to get all the
rust or dirt off.

Nev,. use oil or grease on st,,s or nuts. If you
do, the nuts might come loose. Your wheel
could fall

7. Install the compact spare tire and put the wheel
nuts back on with the rounded end
of the nuts
toward the wheel. Tighten each nut by hand until
the wheel is held against the hub.
8. Lower the vehicle by attaching the folding wheel
wrench to the jack and turning the wrench
counterclockwise. Lower the jack completely.

Electrical System
Add-on Electrical Equipment
Notice: Don’t add anything electrical to your
vehicle unless you check with your dealer first.
Some electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see
Servicing
Your Air Bag-Equipped Vehicle
on page 1-76.
Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in the instrument panel fuse panel. 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 wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
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, be sure to get it fixed.
Power Windows and Other
Power Options
Circuit breakers in the instrument panel 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.
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.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage or use one of the spare fuses in the
underhood fuse block. Just pick some feature of your
vehicle that you can get along without
- like the radio
or cigarette lighter
- and use its fuse, if it is the
right amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle, the instrument
panel fuse block and the underhood fuse block.

Instrument Panel Fuse Block
The instrument panel fuse
block is located to the right
of the glove box on the
end
of the instrument
panel. Pull the
door open
to access the instrument panel
fuse block.

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
Cleaning the Outside of Your Vehicle on page 5-90.
Spare Tire Check
At least twice a year, after the monthly inflation check of
the spare tire determines that the spare is inflated to
the correct tire inflation pressure, make sure that
the spare tire is stored securely. Push, pull, and then try
to rotate or turn the tire.
If it moves, use the folding
wrench to tighten the cable. See
Changing a Flat Tire
on page
5-70.
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
Part D: Recommended Fluids and
Lubricants on page
6-16.
Automatic Transaxle Check
Check the transaxle fluid level; add if needed. See
Automatic Transaxle Fluid on page 5-20. 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 key lock cylinders, hood latch assemblies,
secondary latches, pivots, spring anchor and release
pawl, hood and door hinges, rear folding seats, fuel door
hinge, liftgate hinges, power sliding door cable and
sliding door track(s). Part
D tells you what to use.
More frequent lubrication may be required when
