Front Tire Flat:If the at tire is on a front tire of
the vehicle, you will need to use the jack handle (B)
and only one jack handle extension (C). Attach
the wheel wrench (D) to the jack handle
extension (C). Attach the jack handle (B) to the
jack (A). Position the jack on the frame behind the
at tire near the front body mount (E) as shown.
Turn the wheel wrench (D) clockwise to raise
the vehicle. Raise the vehicle far enough off the
ground so there is enough room for the spare tire to
clear the ground.Rear Tire Flat:If the at tire is on a rear tire of the
vehicle, use the jack handle (B) and both jack
handle extensions (C). Attach the wheel wrench (D)
to the jack handle extensions (C). Attach the jack
handle (B) to the jack (A). Use the jacking pad (E)
provided on the rear axle. Turn the wheel
wrench (D) clockwise to raise the vehicle. Raise the
vehicle far enough off the ground so there is
enough room for the spare tire to clear the ground. Front Position

5. Remove all the
wheel nuts.
6. Take off the at tire.
{CAUTION:
Rust or dirt on a wheel, or on the parts to which it
is fastened, can make wheel nuts become loose
after time. The wheel could come off and cause
an accident. When changing a wheel, remove any
rust or dirt from places where the wheel attaches
to the vehicle. In an emergency, use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if needed, to get all the
rust or dirt off. SeeChanging a Flat Tire on
page 6-77.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces, and
spare wheel.
6-85

8. Install the spare tire.
{CAUTION:
Never use oil or grease on bolts or nuts because
the nuts might come loose. The vehicle’s wheel
could fall off, causing a crash.
9. Put the wheel nuts back on with the rounded
end of the nuts toward the wheel after mounting the
spare tire.
10. Tighten each wheel nut by hand. Then use the
wheel wrench to tighten the wheel nuts until the
wheel is held against the hub.
11. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
{CAUTION:
Incorrect or improperly tightened wheel nuts can
cause the wheel to come loose and even come
off. This could lead to a crash. If you have to
replace them, be sure to get new original
equipment wheel nuts. Stop somewhere as soon
as you can and have the nuts tightened with a
torque wrench to the proper torque specication.
SeeCapacities and Specications on page 6-110
for wheel nut torque specication.
Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specication. SeeCapacities and
Specifications on page 6-110for the wheel nut
torque specication.
6-86

12. Tighten the nuts rmly
in a crisscross
sequence as shown by
turning the wheel
wrench clockwise.
When you reinstall the regular wheel and tire, you must
also reinstall the center cap. Line the tab on the
back of the tab with the slot in the wheel. Place the cap
on the wheel and press until it snaps into place.
Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with a secondary latch system. It is
designed to stop the spare tire from suddenly falling
off your vehicle. For the secondary latch to work,
the spare must be installed with the valve stem pointing
down. SeeStoring a Flat or Spare Tire and Tools on
page 6-90.
{CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly and
you and others could get hurt. Read and follow the
instructions listed next.
To release the spare tire from the secondary latch:
1. Check under the
vehicle to see if the
cable end is visible. If
the cable is not
visible proceed to
Step 6.
6-87

2. If it is visible, rst 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
Step 5 ofRemoving the Spare Tire and Tools on
page 6-78.
5. If the spare does not lower, turn the wrench
counterclockwise until approximately 6 inches
(15 cm) of cable is exposed.
6. Stand the wheel blocks on their shortest ends, with
the backs facing each other.7. Place the bottom edge
of the jack (A) on the
wheel blocks (B),
separating them so that
the jack is balanced
securely.
6-88

8. Attach the jack handle, extension, and wheel
wrench to the jack and place it (with the wheel
blocks) under the vehicle toward the front of the rear
bumper.9. Position the center lift point of the jack under the
center of the spare tire.
10. Turn the wrench clockwise to raise the jack until it
lifts the end tting.
11. Continue raising the jack until the spare tire stops
moving upward and is held rmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.
6-89

12. 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.
{CAUTION:
Someone standing too close during the procedure
could be injured by the jack. If the spare tire does
not slide off the jack completely, make sure no
one is behind you or on either side of you as you
pull the jack out from under the spare.
13. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while rmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, insert the
hoist end of 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.
14. Turn the wheel wrench in the hoist shaft hole in the
bumper clockwise to raise the cable back up if the
cable is hanging under the vehicle.Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or at tire using
the hoist assembly until it has been inspected
and/or replaced.
To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 6-82.
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.
Notice:Storing an aluminum wheel with a at tire
under your vehicle for an extended period of time or
with the valve stem pointing up can damage the
wheel. Always stow the wheel with the valve stem
pointing down and have the wheel/tire repaired
as soon as possible.
Store the tire under the rear of the vehicle in the spare
tire carrier.
