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.
WARNING!
Limited use spares are for emergency use
only. Installation of this limited use spare
tire affects vehicle handling. With this tire,
do not drive more than the speed listed on
the limited use spare wheel. Keep inflated
to the cold tire inflation pressures listed on
your Tire and Loading Information Placard
located on the driver’s side B-Pillar or the
rear edge of the driver’s side door. Replace
(or repair) the original equipment tire at
the first opportunity and reinstall it on your
vehicle. Failure to do so could result in
loss of vehicle control.

Tire Chains (Traction Devices)
Use of traction devices require sufficient
tire-to-body clearance. Follow these recom-
mendations to guard against damage:
Traction device must be of proper size for
the tire, as recommended by the traction
device manufacturer.
Install on front tires only.
For a 215/65R16 tire, use of a snow trac-
tion device with a maximum projection of
7 mm beyond the tire profile is recom -
mended.
No other tire sizes are recommended for
use with a tire chain or traction device.
NOTE:
Any aftermarket tire add on like tire chains
may effect the Tire Pressure Monitoring
System (TPMS) feature performance.
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.
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.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
Because of restricted traction device
clearance between tires and other
suspension components, it is important
that only traction devices in good condi -
tion are used. Broken devices can cause
serious damage. Stop the vehicle imme-
diately if noise occurs that could indi -
cate 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).
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 manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed
of the device manufacturer’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 Front Wheel Drive (FWD) Tire
rotation 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)
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.
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.

preventing the vehicle from resting on the
ground with the body or chassis after
touching the wedge with its lowest and most
projecting parts (usually the underbody),
because this would highly reduce wheel grip.
The wheels, without a suitable grip to the
ground, will not have sufficient hold to move
the vehicle, and will surge.
The higher the ground clearance, the wider
the breakover angle. Always bear in mind
that the higher the ground clearance, the
lower the stability, due to a higher center of
gravity which reduces the side rollover angle.Ground Clearance / Typical Angles
MeasurementsWHEELS
Refer to the tire placard label on the left side
B-pillar or rear edge of the passenger door of
the vehicle or to the Registration Document
for the tire size and pressure. Refer to
“Tires” in the “Servicing And Maintenance”
Chapter for further information.
NOTE:
If there are any discrepancies between the
Owner’s Manual and the Registration Docu -
ment, take the information from the Regis -
tration Document. For safe driving the
vehicle must be fitted with tires of the same
make and type on all wheels.
