1. Your vehicle is equipped with a hoist lock. Open the
spare tire lock cover on the bumper and use the
ignition key to remove the lock.
2. Assemble the wheel wrench and the two jack handle
extensions as shown. Insert the hoist end (open end)
of the extension through the hole in the rear bumper.
Be sure the hoist end of the extension connects into
the hoist shaft.
3. Turn the wheel wrench counterclockwise to lower
the spare tire 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 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 them yet.
2. 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, position the jack under
the rear axle between the spring anchor and the
shock absorber bracket.
NOTICE:
If your vehicle is equipped with
QUADRASTEER
avoid contact with tie rods
and tire rod boots when jacking the vehicle.

Rear Position
3. 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 under the wheel well.
4. Remove all the wheel
nuts and take off the
flat tire.
5. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.

5-27
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.
6. 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 until the
wheel is held
against the hub.

vehicle with the valve stem pointed downward
and to the rear.
2. Tilt the retainer downward and through the wheel
opening. Make sure that 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.

then try to rotate or turn the tire. If the tire moves,
use the wheel wrench/hoist shaft to tighten the cable.
Replace the jack, tools and spare tire lock.
Spare Tire
Your vehicle, when new, had a fully inflated spare tire.
A spare tire may lose air over time, so check its inflation
pressure regularly. See ªInflation
-Tire Pressureº and
ªLoading Your Vehicleº in the Index for information
regarding proper tire inflation and loading your vehicle.
For instruction on how to remove, install or store a spare
tire, see ªChanging a Flat Tireº in the Index.
After installing the spare tire on your vehicle, you
should stop as soon as possible and make sure the spare
is correctly inflated. Have the damaged or flat road tire
repaired or replaced as soon as you can and installed
back onto your vehicle. This way, a spare tire will be
available in case you need it again.
If your vehicle has a spare tire that does not match your
vehicle's original road tires and wheels in size and type,
do not include the spare in the tire rotation.
