Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare
tire and wheel equivalent in look and func-
tion to the original equipment tire and wheel
found on the front or rear axle of your vehicle.
This spare tire may be used in the tire rota -
tion for your vehicle. If your vehicle has this
option, refer to an authorized tire dealer for
the recommended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emer -
gency use only. You can identify if your
vehicle is equipped with a compact spare by
looking at the spare tire description on the
Tire and Loading Information Placard
located on the driver’s side door opening or
on the sidewall of the tire. Compact spare
tire descriptions begin with the letter “T” or
“S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire Since this tire has limited tread life, the orig
-
inal equipment tire should be repaired (or
replaced) and reinstalled on your vehicle at
the first opportunity.
Do not install a wheel cover or attempt to
mount a conventional tire on the compact
spare wheel, since the wheel is designed
specifically for the compact spare tire. Do
not install more than one compact spare tire
and wheel on the vehicle at any given time.
Full Size Spare — If Equipped
The full size spare is for temporary emer -
gency use only. This tire may look like the
originally equipped tire on the front or rear
axle of your vehicle, but it is not. This spare
tire may have limited tread life. When the
tread is worn to the tread wear indicators, the
temporary use full size spare tire needs to be
replaced. Since it is not the same as your
original equipment tire, replace (or repair)
the original equipment tire and reinstall on
the vehicle at the first opportunity.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary
emergency use only. This tire is identified by
a label located on the limited use spare
wheel. This label contains the driving limita -
tions for this spare. This tire may look like
the original equipped tire on the front or rear
axle of your vehicle, but it is not. Installation
of this limited use spare tire affects vehicle
handling. Since it is not the same as your
original equipment tire, replace (or repair)
the original equipment tire and reinstall on
the vehicle at the first opportunity.
WARNING!
Compact and collapsible spares are for
temporary emergency use only. With these
spares, do not drive more than 50 mph
(80 km/h). Temporary use spares have
limited tread life. When the tread is worn
to the tread wear indicators, the temporary
use spare tire needs to be replaced. Be
sure to follow the warnings, which apply to
your spare. Failure to do so could result in
spare tire failure and loss of vehicle
control.

CAUTION!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing
compounds. They will permanently
damage this finish and such damage is not
covered by the New Vehicle Limited
Warranty. HAND WASH ONLY USING
MILD SOAP AND WATER WITH A SOFT
CLOTH. Used on a regular basis; this is all
that is required to maintain this finish.
WARNING!
Using tires of different size and type
(M+S, Snow) between front and rear axles
can cause unpredictable handling. You
could lose control and have a collision.

Tire Rotation Recommendations
The tires on the front and rear of your vehicle
operate at different loads and perform
different steering, handling, and braking
functions. For these reasons, they wear at
unequal rates.These effects can be reduced by timely rota
-
tion of tires. The benefits of rotation are
especially worthwhile with aggressive tread
designs such as those on On/Off Road type
tires. Rotation will increase tread life, help to
maintain mud, snow, and wet traction levels,
and contribute to a smooth, quiet ride.
Refer to the “Maintenance Plan” for the
proper maintenance intervals. The reasons
for any rapid or unusual wear should be
corrected prior to rotation being performed.
The suggested Front Wheel Drive (FWD) rota -
tion method is the “forward cross” shown in
the following diagram. This rotation pattern
does not apply to some directional tires that
must not be reversed.
Tire Rotation (Forward Cross)
CAUTION!
Use on Front Tires Only
Damage to Front Wheel Drive (FWD)
Models may result if tire chains or trac-
tion devices are used with original equip -
ment size tires.
Damage to Four Wheel Drive (4WD)
Models without a Two-Speed Power
Transfer Unit may result if tire chains or
traction devices are used with original
equipment size tires.
Damage to Four Wheel Drive (4WD)
Trailhawk Models may result if tire
chains or traction devices are used with
original equipment size tires.
To avoid damage to your vehicle or tires,
observe the following precautions:

Because of restricted traction device clear -
ance between tires and other suspension
components, it is important that only trac -
tion devices in good condition are used.
Broken devices can cause serious damage.
Stop the vehicle immediately if noise
occurs that could indicate device
breakage. Remove the damaged parts of
the device before further use.

Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km). Autosock traction devices do
not require retightening.
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns
and large bumps, especially with a
loaded vehicle.
Do not drive for a prolonged period on
dry pavement.

Observe the traction device manufac -
turer’s instructions on the method of
installation, operating speed, and condi -
tions for use. Always use the suggested
operating speed of the device manufac -
turer’s if it is less than 30 mph (48 km/h).

Do not use traction devices on a compact
spare tire.
CAUTION! (Continued)

The suggested Four Wheel Drive (4WD) Tire
rotation method is the “rearward cross”
shown in the following diagram.Tire Rotation (Rearward Cross)STORING THE VEHICLE
If the vehicle should remain stationary for
more than a month, observe the following
precautions:
Park your vehicle in a covered, dry and
possibly airy location the windows open
slightly.
Check that the Electric Park Brake is not
engaged.
Disconnect the negative (-) terminal from
the battery post and be sure that the
battery is fully charged. During storage
check battery charge quarterly.
If you do not disconnect the battery from
the electrical system, check the battery
charge every 30 days.
Clean and protect the painted parts by
applying protective waxes.
Clean and protect polished metal parts by
applying protective waxes.
Apply talcum powder to the front and rear
wiper blades and leave raised from the
glass.
Cover the vehicle with an appropriate
cover taking care not to damage the
painted surface by dragging across dirty
surfaces. Do not use plastic sheeting
which will not allow the evaporation of
moisture present on the surface of the
vehicle.
Inflate the tires at a pressure of +7.25 psi
(+0.5 bar) higher than recommended on
the tire placard and check it periodically.
Do not drain the engine cooling system.
Whenever you leave the vehicle stationary
for two weeks or more, idle the engine for
approximately five minutes, with the air
conditioning system on and high fan
speed. This will ensure proper lubrication
of the system, thus minimizing the possi -
bility of damage to the compressor when
the vehicle is put back into operation.
NOTE:
When the vehicle has not been started or
driven for at least 30 days, an Extended Park
Start Procedure is required to start the
vehicle.
Refer to “Starting The Engine” in “Starting
And Operating” for further information. CAUTION!
Proper operation of four-wheel drive
vehicles depends on tires of equal size,
type and circumference on each wheel.
Any difference in tire size can cause
damage to the power transfer unit. Tire
rotation schedule should be followed to
balance tire wear.

WHEEL AND TIRE TORQUE
SPECIFICATIONS
Proper lug nut/bolt torque is very important
to ensure that the wheel is properly mounted
to the vehicle. Any time a wheel has been
removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a
properly calibrated torque wrench using a
high quality six sided (hex) deep wall socket.
Torque Specifications
**Use only authorized dealer recommended
lug nuts/bolts and clean or remove any dirt or
oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion
or loose particles.
Tighten the lug nuts/bolts in a star pattern
until each nut/bolt has been tightened twice.
Ensure that the socket is fully engaged on
the lug nut/bolt (do not insert it halfway).Torque Pattern
After 25 miles (40 km), check the lug nut/
bolt torque to be sure that all the lug nuts/
bolts are properly seated against the wheel.
WHEELS
Refer to the tire placard label located on the
door sill of the vehicle or to the Registration
Document for the tire size and pressure.
Refer to “Tires” in the “Servicing and main -
tenance” for further information.
