Removing the Flat Tire and
Installing the Spare Tire
To remove the at tire and install the spare:
1. Do a safety check before proceeding. SeeChanging
a Flat Tire on page 5-76for more information.
2. Loosen the wheel nuts, but do not remove them
yet, using the wheel wrench. Turn the handle
about 180 degrees, then ip the handle back to the
starting position. This avoids taking the wrench
off the lug nut for each turn.3. Find the jacking location using the V–shaped
notches located in the plastic molding.
4. Attach the wheel wrench to the jack.
{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:
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 you
change a wheel, remove any rust or dirt from
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 needed, to get
all the rust or dirt off. SeeChanging a Flat Tire
on page 5-76.

{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 Specifications
on page 5-111for 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.
16. Do not try to put a wheel cover on the compact
spare tire. It will not t. Store the wheel cover
securely in the rear of the vehicle until you have
the at tire repaired or replaced.
Secondary Latch System
Your vehicle has an underbody mounted tire hoist
assembly that has a secondary latch system. It is
designed to stop the compact spare tire from suddenly
falling off your vehicle if the cable holding the spare
tire is damaged. For the secondary latch to work, the tire
must be stowed with the valve stem pointing down.
SeeStoring a Flat or Spare Tire and Tools on page 5-87
for instructions on storing the spare tire correctly.
{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.

{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 the under spare.
To release the spare tire from the secondary latch:
1. If the cable is not visible, start this procedure
at Step 3.
2. If the cable is visible,
place the wrench on
the hoist drive nut
and turn the wrench
counterclockwise
until approximately
6 inches (15 cm)
of cable is exposed.3. Attach the wheel wrench to the jack and raise
the jack at least 10 turns.
4. Place the jack under the vehicle, ahead of the
rear bumper. Position the center lift point of the
jack under the center of the spare tire.
5. Turn the wheel wrench clockwise to raise the
jack until it lifts the secondary latch spring.
6. Keep raising the jack until the spare tire stops
moving upward and is held rmly in place, this lets
you know that the secondary latch has released.
7. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until
the spare tire is resting on the wheel wrench.

center hole of the spare tire.
Make sure the retainer is fully seated across the
underside of the wheel.

turn the tire so that the valve stem is towards
the rear of the vehicle.
This will help when you check and maintain tire
pressure in the spare.7. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench until you
feel more than two clicks. This indicates that the
compact spare tire is secure and the cable is tight.
The spare tire hoist cannot be overtightened.
