CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
•Use chains on P225/65R16 tires only. P225/65R17
tires do not provide adequate clearance.
•Because of restricted chain clearance between tires
and other suspension components, it is important
that only chains in good condition are used. Bro-
ken chains can cause serious damage. Stop the
vehicle immediately if noise occurs that could
indicate chain breakage. Remove the damaged
parts of the chain before further use.
•Do not exceed 45 mph (70 km/h).
•Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.(Continued)
CAUTION! (Continued)
•Install chains on the front wheels as tightly as
possible and then retighten after driving about
0.5 mile (0.8 km).
•Do not drive for prolonged periods of time on dry
pavement.
•Observe the tire chain manufacturer’s instructions
on the method of installation, operating speed,
and conditions for use. Always use the lower
suggested operating speed of the chain manufac-
turer, if different from the speed recommended by
the vehicle manufacturer.
Always use the lower suggested operating speed if the
chain manufacturer and vehicle manufacturer suggest
different maximum speeds. This notice applies to all
chain traction devices, including link and cable (radial)
chains.

SNOW TIRES
Some areas of the country require the use of snow tires
during the winter. All season tires can be identified by the
M+S designation on the tire sidewall.
If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of four; failure to do so may adversely affect the
safety and handling of your vehicle.
Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should
not be operated at sustained speeds over 75 mph
(120 km/h). For speeds above 75 mph (120 km/h) refer to
original equipment or an authorized tire dealer for
recommended safe operating speeds, loading and cold
tire inflation pressures.
While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may bepoorer than that of non-studded tires. Some states pro-
hibit studded tires; therefore, local laws should be
checked before using these tire types.
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle operate at
different loads and perform different steering, driving,
and braking functions. For these reasons, they wear at
unequal rates.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season 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 Schedule” for the proper
maintenance intervals. The reasons for any rapid or
unusual wear should be corrected prior to rotation being
performed.

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement
equipment that is not of the same size, type, and/or
style. Aftermarket wheels can cause sensor dam-
age. Do not use aftermarket sealants or balance
beads if your vehicle is equipped with a TPMS, as
damage to the sensors may result.
•After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPMS sensor.NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to maintain
correct tire pressure, using an accurate tire pressure
gage, even if under-inflation has not reached the level
to trigger illumination of the “Tire Pressure Monitor-
ing Telltale Light.”

The manufacturer supports the use of reformulated gaso-
line. Properly blended reformulated gasoline will pro-
vide excellent performance and durability of engine and
fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as Ethanol. Fuels blended with oxygenates
may be used in your vehicle.
CAUTION!
DO NOT use gasoline containing Methanol or gaso-
line containing more than 10% Ethanol. Use of these
blends may result in starting and driveability prob-
lems, damage critical fuel system components, cause
emissions to exceed the applicable standard, and/or
cause the “Malfunction Indicator Light” to illumi-
nate. Pump labels should clearly communicate if a
fuel contains greater than 10% Ethanol.Problems that result from using gasoline containing
Methanol or gasoline containing more than 10% Ethanol
are not the responsibility of the manufacturer and may
not be covered under warranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold driveability
•increased risk for fuel system component corrosion

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
•An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
service. Contact your authorized dealer for service
assistance.(Continued)
CAUTION! (Continued)
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentra-
tions of methanol. Fuel system damage or vehicle
performance problems resulting from the use of
such fuels or additives is not the responsibility of
the manufacturer.
NOTE: Intentional tampering with the emissions con-
trol system can result in civil penalties being assessed
against you.

12. Stow the jack, jack handle and winch handle tools
back in the stowage compartment.
13. Check the compact spare tire pressure as soon as
possible. Correct the tire pressure, as required.
Wheel Nuts
All wheel nuts should be tightened occasionally, to
eliminate the possibility of wheel studs being sheared or
the bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles
of operation, and after each time a tire is changed, to
allow the wheel nuts to become properly set. All nuts
should first be firmly seated against the wheel. The nuts
should then be tightened to recommended torque.
Tighten the nuts to final torque in increments. Progress
around the bolt circle, tightening the nut opposite to the
nut just previously tightened until final torque is
achieved. Recommended torque is 102 ft lbs (138 N·m).
Securing The Spare Tire
1. Assemble the winch handle extensions to form a
T-handle and fit the winch T-handle over the drive nut.
Rotate the nut to the left until the winch mechanism stops
turning freely. This will allow enough slack in the cable to
allow you to pull the wheel spacer out from under the
vehicle.
WARNING!
A loose compact spare tire/cover assembly, thrown
forward in a collision or hard stop could endanger
the occupants of the vehicle. Always stow the com-
pact spare tire with the cover assembly in the place
provided.

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then move the shift lever back and forth
between DRIVE and REVERSE. Using minimal accelera-
tor pedal pressure to maintain the rocking motion, with-
out spinning the wheels, is most effective.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the shift lever in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of transmission failure during prolonged
efforts to free a stuck vehicle.NOTE:
To improve the vehicle’s traction when starting
off in deep snow, sand or gravel, it may be desirable to
switch the Electronic Stability Program (ESP) to “Partial
Off” mode. Refer to “Electronic Brake Control System” in
“Starting and Operating” for further information.
CAUTION!
•When “rocking” a stuck vehicle by moving be-
tween DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
•Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).6

•Mix a minimum solution of 50% HOAT engine coolant
and distilled water. Use higher concentrations (not to
exceed 70%) if temperatures below34°F (37°C) are
anticipated.
•Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
(antifreeze) solution. The use of lower quality water
will reduce the amount of corrosion protection in the
engine cooling system.
Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE: Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (antifreeze) and
will require more frequent coolant changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent the loss of
engine coolant (antifreeze), and to ensure that engine
coolant (antifreeze) will return to the radiator from the
coolant recovery bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
