the ground so there is enough
room for the spare tire to clear
the ground.
Rear Positions
Refer to the graphic above to
locate the placement of the jack
if the flat tire is on the rear of the
vehicle.
Rear Tire Flat: Use the jack
handle and both jack handle
extensions. Attach the wheel
wrench to the jack extensions.
Attach the jack handle to the
jack. From the rear of the vehicle

head to the lifting point.
{WARNING
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.
{WARNING
Raising your vehicle with the
jack improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle.

7. Remove all the wheel nuts andtake off the flat tire.
{WARNING
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. See If a Tire Goes Flat
on page 10‑64. 8. Remove any rust or dirt from the
wheel bolts, mounting surfaces
and spare wheel.
{WARNING
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 spare tire on the mounting surface.
10. Put the wheel nuts back on with the rounded end of the
nuts toward the wheel after
mounting the spare. 11. Tighten each wheel nut by
hand. Then use the wheel
wrench to tighten the nuts until
the wheel is held against
the hub.
12. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack
completely.

Vehicle Care 10-81
{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. SeeCapacities and
Specifications
on page 12‑2for
original equipment wheel nut
torque specifications. 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 specification. See
Capacities and Specifications
on
page 12‑2for the wheel nut
torque specification.
13. Tighten the nuts firmly in a crisscross sequence as shown
by turning the wheel wrench
clockwise.
14. After installing the wheel and tire, reinstall the center cap.
Place the cap on the wheel and
tap it into place until it sits flush

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.

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
Changing (H3T)
on page 10‑66or
Tire Changing (H3) on page 10‑75.

10-86 Vehicle Care
After installing the spare tire on your
vehicle, you should stop as soon as
possible and make sure the spare is
correctly inflated.
The spare tire does not have a Tire
Pressure Monitor System sensor.
You may get a low pressure warning
light. SeeTire Pressure Monitor
Operation
on page 10‑53. Have the
damaged or flat road tire repaired or
replaced as soon as you can.
Do not mix tires and wheels of
different sizes, because they will
not fit. Keep your spare tire and its
wheel together.
Jump Starting
If the vehicle's battery has run
down, you may want to use another
vehicle and some jumper cables to
start your vehicle. Be sure to use
the following steps to do it safely.
{WARNING
Batteries can hurt you. They can
be dangerous because:
.They contain acid that can
burn you.
.They contain gas that can
explode or ignite.
.They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you. Notice:
Ignoring these steps
could result in costly damage to
the vehicle that would not be
covered by the warranty.
Trying to start the vehicle by
pushing or pulling it will not
work, and it could damage the
vehicle.
1. Check the other vehicle. It must
have a 12‐volt battery with a
negative ground system.
Notice: If the other vehicle's
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.
2. Get the vehicles close enough so the jumper cables can reach,
but be sure the vehicles are not
touching each other. If they
are, it could cause a ground
connection you do not want.
