Snow Tires
Some areas of the country require the use of snow tires
during the Winter. Snow tires can be identified by a “moun-
tain/snowflake” symbol 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 be poorer than
that of non-studded tires. Some states prohibit studded tires;
therefore, local laws should be checked before using these
tire types.Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit instead of a spare
tire, please refer to “Tire Service Kit” in “In Case Of Emer -
gency” for further information.
Refer to the “Towing Requirements - Tires” in “Starting And
Operating” for restrictions when towing with a spare tire
designated for temporary emergency use.
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 function 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 rotation for your
vehicle. If your vehicle has this option, refer to an authorized
tire dealer for the recommended tire rotation pattern.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with a
compact or limited use temporary spare installed.
Damage to the vehicle may result.

Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart
significantly from the norm due to variations in driving
habits, service practices, and differences in road charac-
teristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A, B,
and C. These grades represent the tire's ability to stop on
wet pavement, as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor -
mance. Temperature Grades
The Temperature grades are A (the highest), B, and C,
representing the tire's resistance to the generation of heat
and its ability to dissipate heat, when tested under
controlled conditions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the material of the
tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C
corresponds to a level of performance, which all
passenger vehicle tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the laboratory
test wheel, than the minimum required by law.WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or peak
traction characteristics.

470 SERVICING AND MAINTENANCE
STORING THE VEHICLE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to minimize
the drain on your vehicle's battery:
• Disconnect the negative cable from battery.
• Any time you store your vehicle or keep it out of service(i.e., vacation) for two weeks or more, run the air condi -
tioning system at idle for about five minutes in the fresh air
and high blower setting. This will ensure adequate system
lubrication to minimize the possibility of compressor
damage when the system is started again.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according to
geographic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on trees
and road surfaces during other seasons are highly corrosive
to the metal in your vehicle. Outside parking, which exposes
your vehicle to airborne contaminants, road surfaces on
which the vehicle is operated, extreme hot or cold weather
and other extreme conditions will have an adverse effect on
paint, metal trim, and underbody protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion resistance
built into your vehicle.
WARNING!
The temperature grade for this tire is established for a
tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive loading,
either separately or in combination, can cause heat
buildup and possible tire failure.

TECHNICAL SPECIFICATIONS 479
The wheel nuts should then be tightened to recommended
torque. Tighten the wheel nuts to final torque in increments.
Progress around the bolt circle, tightening the wheel nut
opposite to the wheel nut just previously tightened until
final torque is achieved.
FUEL REQUIREMENTS
6.4L Engine
Do not use E-85 flex fuel or ethanol blends greater than 15%
in this engine.This engines is designed to meet all emissions regu -
lations and provide satisfactory fuel economy and
performance when using high quality unleaded
gasoline having a posted octane number range of 87 to 89 as
specified by the (R+M)/2 method. The use of 89 octane
“Plus” gasoline is recommended for optimum performance
and fuel economy. While operating on gasoline with an octane number of 87,
hearing a light knocking sound from the engine is not a cause
for concern. However, if the engine is heard making a heavy
knocking sound, see your dealer immediately. Use of gaso
-
line with an octane number lower than 87 can cause engine
failure and may void or not be covered by the New Vehicle
Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before considering
service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner burning
gasoline referred to as “Reformulated Gasoline”. Reformu-
lated gasoline contains oxygenates and are specifically
blended to reduce vehicle emissions and improve air quality.
The use of reformulated gasoline is recommended. Properly
blended reformulated gasoline will provide improved
performance and durability of engine and fuel system
components.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may result
in personal injury.

NOTE:
Intentional tampering with the emissions control system can
result in civil penalties being assessed against you.
Carbon Monoxide Warnings
• An out-of-tune engine or certain fuel or ignitionmalfunctions can cause the catalytic converter to over -
heat. 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 an authorized dealer for service assistance.
• The use of fuel additives, which are now being sold as octane enhancers, is not recommended. Most of these
products contain high concentrations 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 and may void or
not be covered under the New Vehicle Limited
Warranty. CAUTION!
(Continued)WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They contain carbon monoxide, a colorless and odorless gas, which can kill.
Never run the engine in a closed area, such as a garage,
and never sit in a parked vehicle with the engine
running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
• Guard against carbon monoxide with proper mainte -
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
