Storing a Flat or Spare Tire
and Tools
{WARNING
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.
To store the flat or spare tire on the
spare tire mount:
1. Slide the flat or spare tire onto the swing-gate.
You may need assistance to
do this.
2. Reinstall the nuts to retain the flat or spare tire.
3. Tighten the nuts by hand.
{WARNING
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. See Capacities and
Specifications
on page 12‑2for
original equipment wheel nut
torque specifications.
4. Use the wheel wrench to tighten the nuts firmly. Try to move the
tire back and forth slightly to be
sure it is secure.
5. Reinstall the center tire cover onto the spare or flat tire.
6. If the vehicle has a spare tire cover close the cover and latch
the side latch.

2. Secure the tool bag to the jackby securely wrapping the straps
around the jack. Then, slide the
straps through the rings on the
bag and secure. 3. Position the jack and jack tool
bag in the swing-gate.
When reinstalling the jack and
jack tool bag, make sure the jack
base is securely seated behind
the tabs in the swing-gate.
4. Reinstall the wing nut retainer tofasten the jack and tool bag in
the storage compartment.
Make sure that the wing nut
passes through the tool bag and
the jack before tightening it. 5. Turn the wing nut retainer
clockwise to secure.
6. Reinstall the compartment cover by inserting the locator tabs in
the holes in the swing-gate.
Push the latches down to
secure.

10-84 Vehicle Care
Secondary Latch System
This vehicle has an underbody
mounted tire hoist assembly that
has a secondary latch system. It is
designed to stop the spare tire from
suddenly falling off the 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.
SeeTire Changing (H3T)
on
page 10‑66or Tire Changing (H3)on page 10‑75for instructions on
storing the spare tire correctly.
{WARNING
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:
{WARNING
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.
1. If the cable is not visible, start this procedure at Step 3.
2. Turn the lug wrench
counterclockwise until
approximately 6 inches (15 cm)
of cable is exposed.
3. Attach the lug 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.

Vehicle Care 10-85
5. Turn the lug wrench clockwise toraise the jack until it lifts the
secondary latch spring.
6. Keep raising the jack until the spare tire stops moving upward
and is held firmly in place. This
lets you know that the secondary
latch has released and the spare
tire is balancing on the jack.
7. Lower the jack by turning the lugwrench counterclockwise. Keep
lowering the jack until the spare
tire slides off the jack.
8. Disconnect the lug wrench fromthe jack and carefully remove
the jack. Use one hand to push
against the spare tire while
firmly pulling the jack out from
under the spare tire with the
other hand. 9. Tilt the retainer and slip it
through the wheel opening
when the spare tire has been
completely lowered.
10. Turn the lug wrench clockwise to raise the cable back up if the
cable is hanging.
Have the hoist shaft assembly
inspected as soon as you can. You
will not be able to store a spare tire
using the hoist assembly until it has
been repaired or replaced.
Full-Size Spare Tire
The vehicle, when new, had a
fully-inflated spare tire. A spare tire
may lose air over time, so check its
inflation pressure regularly. See Tire
Pressure
on page 10‑51and Vehicle
Load Limitson page 9‑27for
information regarding proper tire
inflation and loading your vehicle.
For instruction on how to remove,
install or store a spare tire, see Tire
