model has a jack cover,
turn the wing nut
counterclockwise and
take the cover off.

and take it and the retainer off. Take the jack and storage
box out and take the tools out of the box.
Your vehicle may have a pair of emergency gloves
secured to the jack. You can use them when changing
the tire, or during other emergency situations.
Remember to replace them with the jack, so you will
have them if needed later.
To open the jack cover on four-door utility models, turn
the wing nut counterclockwise and take the cover off.
To take the jack out, turn the wing
-head bolt
counterclockwise and take it and the retainer off. Take
the jack and storage box out and take the tools out of
the box.
Your vehicle may have a pair of emergency gloves
secured to the jack. You can use them when changing
the tire, or during other emergency situations.
Remember to replace them with the jack, so you will
have them if needed later.

the retainer bolt.
3. Slide the adapter onto the bolt in the proper location
for your model and put the wing nut on.

6-61 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. See ªFuses and Circuit Breakersº in the Index
for more information.
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. 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 correct amperage.
Replace it as soon as you can.Instrument Panel Fuse Block
The fuse block access door
is on the driver's side edge
of the instrument panel. Pull
off the cover to access the
fuse block.
You can remove fuses with
a fuse extractor. The fuse
extractor is mounted to the
fuse block access door.
To remove fuses, if you don't have a fuse extractor, hold
the end of the fuse between your thumb and index finger
and pull straight out.
You may have spare fuses attached to the inside of
the fuse block access door. These can be used to
replace a bad fuse. However, make sure that it is the
correct amperage.

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.
Air Cleaner Filter Restriction Indicator Check
Your vehicle has an indicator on the engine that lets you
know when the air cleaner filter is dirty and needs to be
changed. Check indicator at least twice a year or when
your oil is changed, whichever occurs first. See ªAir
Cleanerº in the Index for more information. Inspect your
air cleaner filter restriction indicator more often if the
vehicle is used in dusty areas or under off road conditions.
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 Transmission Check
Check the transmission fluid level; add if needed. See
ªAutomatic Transmission Fluidº in the Index. A fluid
loss may indicate a problem. Check the system and
repair if needed.
At Least Once a Year
