TIRE QUALITY GRADES
The following tire grading categories were established by
the National Highway Traffic Safety Administration. The
specific grade rating assigned by the tire's manufacturer
in each category is shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform to Federal safety
requirements in addition to these grades.
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 spec
-
ified government test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Temperature Grades
The Temperature grades are A (the highest), B, and C, repre -
senting the tire's resistance to the generation of heat and its
ability to dissipate heat, when tested under controlled condi -
tions on a specified indoor laboratory test wheel.
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.

SERVICING AND MAINTENANCE 539
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.
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 549
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 an dealer immediately. Use of gasoline
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.
5.7L Engine
Do not use E-85 flex fuel or ethanol blends greater than 15%
in this engine.This engine is designed to meet all emissions regula -
tions and provide satisfactory fuel economy and
performance when using high-quality unleaded
gasoline having an octane 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.

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.
