the following:
1. Check under the vehicle to see if the cable end is
visible.
2. If it is not visible proceed to step 6.
If it is visible, first try to tighten the cable by turning
the wheel wrench clockwise until you hear two
clicks or feel it skip twice. You cannot overtighten
the cable.
3. Loosen the cable by turning the wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times, if the
spare tire lowers to the ground, continue with

5. Turn the wrench counterclockwise until
exposed.
6. Stand the wheel blocks
on their shortest ends,
with the backs
facing each other.

blocks, separating them
so that the jack is
balanced securely.
8. Attach the jack handle, extension, and wheel
wrench to the jack and place it (with the wheel
blocks) under the vehicle towards the front of the
rear bumper. Position the center
lift point of the jack
under the center of the spare tire.

9. Turn the wrench clockwise to raise the jack until it
lifts the end fitting.
10. Continue raising the jack until the spare tire stops
moving upward and is held firmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.
11. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until the
spare tire slides
off the jack or is hanging by
the cable.
12. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand
to
push against the spare while firmly pulling the jack
out from under the spare with the other hand.
If the spare is hanging from the cable, insert the
hoist handle, extension and wheel wrench into the
hoist shaft hole in the bumper and turn the
wheel wrench counterclockwise to lower the spare
the rest of the way.
13. Tilt the retainer at the end of the cable and pull it
through the wheel opening. Pull the tire out from
under the vehicle.
14. If the cable is hanging under the vehicle, turn the
wheel wrench in the hoist shaft hole in the bumper
clockwise to raise the cable back up.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or flat tire using
the hoist assembly until it has been replaced.

1. Use the wheel wrench
to loosen all the wheel
nuts. Turn the wheel
wrench
counterclockwise to
loosen the wheel nuts.

Location
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
QUADRASTEERTM avoid contact with tie rods and
tie 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.
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.

5. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
Never use
oil or grease on studs or nuts. It
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.

Storing a Flat or Spare Tire and Tools
--xing a jack, a --:e, or ---ier 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.
Notice: An aluminum wheel with a flat tire should
always be stored under the vehicle with the hoist. However, storing
it that way for an extended
period
of time could damage the wheel. To avoid
this, always stow the wheel properly with the valve
stem pointing down and have the wheel repaired
as soon as possible.
Return the bottle jack, wheel blocks, wheel wrench and
jack extensions to their location under the passenger’s
side second row seat. Secure the items in the vehicle as
shown.

across the underside of the wheel.
3. Attach the wheel wrench and extensions together.
Insert the hoist end through the hole in the rear

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/hoist shaft to tighten
the cable.
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
Inflation -- Tire Pressure
on page 5-62 and Loading Your Vehicle on page 4-45
for information regarding proper tire inflation and loading
your vehicle. For instruction on how to remove, install
or store a spare tire, see
Changing a Flat Tire on
page
5-69.
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.
Replace the jack, tools and spare tire
lock, if equipped.
