Extension ToolFollow these instructions to lower the spare tire:
1. If the vehicle is equipped with a hoist lock (I), open
the spare tire lock cover on the bumper and use the
ignition key to remove the lock.
2. Assemble the wheel wrench (B) and the two jack
handle extensions (C) as shown. Insert the hoist
end (K) (open end) of the extension through the
hole (J) in the rear bumper. Be sure the hoist end
of the extension connects into the hoist shaft (D)
(the ribbed square end of the extension is used to
lower the spare tire).
3. Turn the wheel wrench counterclockwise to lower
the spare tire (F) to the ground. Continue to turn the
wheel wrench until the spare tire can be pulled out
from under the vehicle. The wheel wrench has a
hook that allows you to pull the hoist cable (H)
towards you, to assist in reaching the spare tire.
4. When the tire has been lowered, tilt the retainer at
the end of the cable so it can be pulled up through
the wheel opening.
5. Put the spare tire near the flat tire.

5-24 Removing the Flat Tire and Installing the
Spare Tire
1. Use the wheel wrench to loosen all the wheel nuts.
Turn the wheel wrench counterclockwise to loosen
the wheel nuts. Don't remove the wheel nuts yet.
Position the jack under the vehicle. If the flat tire is
on the front of the vehicle, position the jack on the
frame behind the flat tire.
If the flat tire is on the rear of the vehicle, use the
jacking pad provided on the rear axle.
CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to fit the jack
lift head into the proper location before raising
the vehicle.

2. For the front position, make sure that the jack is
positioned where the sections of frame overlap.
For the rear, make sure the jack head is positioned
so that the rear axle is resting securely between the
grooves that are on the jack head. Turn the wheel
wrench clockwise to raise the vehicle. Raise the
vehicle far enough off the ground so there is enough
room for the spare tire to fit back underneath the rear
of the vehicle.

3. Remove all the wheel
nuts and take off the
flat tire.
4. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
CAUTION:
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.
CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.

5. After mounting the
spare, put the wheel
nuts back on with the
rounded end of the
nuts toward the wheel.
Tighten each wheel
nut by hand. Then use
the wheel wrench to
tighten the nuts until
the wheel is held
against the hub.

6. Turn the wheel wrench
counterclockwise to
lower the vehicle. Lower
the jack completely.

5-29 Storing a Flat or Spare Tire and Tools
CAUTION:
Storing a jack, a tire or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
Store the tire under the rear of the vehicle in the spare
tire carrier. To store the tire do the following:
1. Put the tire on the ground at the rear of the vehicle
with the valve stem pointed upward.
2. Tilt the retainer downward and through the wheel
opening. Make sure the retainer is fully seated across
the underside of the wheel.
3. Attach the wheel wrench and extensions together.
Insert the hoist end through the hole in the rear
bumper and into the hoist shaft.
4. Raise the tire partway upward. Make sure the
retainer is seated in the wheel opening.5. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench until the
tire is secure and the cable is tight. The spare tire
hoist cannot be overtightened.
6. Make sure the tire is stored securely. Push, pull, and
then try to rotate or turn the tire. If the tire moves,
use the wheel wrench to tighten the cable.
Replace the jack, tools and spare tire lock.

6-42 Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See ªWhen It's Time for New Tiresº and
ªWheel Replacementº later in this section for more
information. Make sure the spare tire is stored securely.
Push, pull, and then try to rotate or turn the tire. If it
moves, use the wheel wrench to tighten the cable. See
ªStoring a Flat or Spare Tire and Toolsº in the Index.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See ªScheduled
Maintenance Servicesº in the Index for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here. Don't include the spare tire in your
tire rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the
Certification/Tire label. Make certain that all wheel
nuts are properly tightened. See ªWheel Nut Torqueº in
the Index.

7-17 At Least Twice a Year
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.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 wheel
wrench/ratchet to tighten the cable. See ªStoring the
Spare Tire and Toolsº in the Index.
Engine Air Cleaner Filter Restriction
Indicator Check
Your vehicle has an indicator located on the air cleaner
in the engine compartment 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 engine 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.
