378SERVICING AND MAINTENANCE
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12°F (7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the Winter.
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds and
within posted speed limits. Where speed limits or
conditions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle operation.
Refer to an authorized tire dealer or original equipment
vehicle dealer for recommended safe operating speeds,
loading and cold tire inflation pressures.
Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be repaired if it
meets the following criteria:
The tire has not been driven on when flat
 The damage is only on the tread section of your tire
(sidewall damage is not repairable)
 The puncture is no greater than ¼ of an inch (6 mm)
Consult an authorized tire dealer for tire repairs and
additional information. Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical size and
service description (Load Index and Speed Symbol).
Replace the tire pressure sensor as well as it is not
designed to be reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the
Run Flat mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi (96 kPa).
Once a Run Flat tire reaches the Run Flat mode it has
limited driving capabilities and needs to be replaced
immediately. A Run Flat tire is not repairable. When a Run
Flat tire is changed after being driven in a Run Flat mode
14 psi (96 kPa) condition, please replace the TPMS sensor
as it is not designed to be reused.
NOTE:The TPMS Sensor must be replaced after driving the
vehicle on a flat tire condition.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the
Run Flat mode.
For more information
Úpage 277.
WARNING!
High speed driving with your vehicle under maximum
load is dangerous. The added strain on your tires could
cause them to fail. You could have a serious collision.
Do not drive a vehicle loaded to the maximum capacity
at continuous speeds above 75 mph (120 km/h).
WARNING!
Combining radial ply tires with other types of tires on
your vehicle will cause your vehicle to handle poorly.
The instability could cause a collision. Always use radial
ply tires in sets of four. Never combine them with other
types of tires.

SERVICING AND MAINTENANCE379
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle's wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously without stopping.
For further information
Úpage 329.
Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be
replaced.

Tire Tread

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire should be
replaced.
For further information
Úpage 380.
Life Of Tire
The service life of a tire is dependent upon varying factors
including, but not limited to:
Driving style
 Tire pressure - Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire
replacement
 Distance driven
 Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle
scheduled maintenance is highly recommended
NOTE:Wheel Valve Stem must be replaced as well when
installing new tires due to wear and tear in existing tires.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause tire damage or
failure. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than 30 mph
(48 km/h) for more than 30 seconds continuously
when you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.
1 — Tread Wear Indicators
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting in
serious injury or death.

SERVICING AND MAINTENANCE381
Snow Tires
Some areas of the country require the use of snow tires
during the Winter. Snow tires can be identified by a
“mountain/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
Emergency” for further information.
For restrictions when towing with a spare tire designated
for temporary emergency use
Úpage 179.
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.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency 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 original 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.
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.
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.8

SERVICING AND MAINTENANCE387
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
characteristics 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 performance.
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.
STORING THE VEHICLE
If you are storing your vehicle for more than three weeks,
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.
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.
WARNING!
The temperature grade for this tire is established for a
tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading,
either separately or in combination, can cause heat
buildup and possible tire failure.

FUEL REQUIREMENTS
While operating on gasoline with the required octane
number, 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 a dealer
immediately. Use of gasoline with a lower than
recommended octane number 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.
3.6L 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
regulations and provide optimum fuel economy
and performance when using high quality
unleaded regular gasoline having a posted
octane number of 87 as specified by the (R+M)/2 method.
The use of higher octane premium gasoline is not
required, as it will not provide any benefit over regular
gasoline in these engines.
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
regulations 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.
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner-burning gasoline referred to as “reformulated
gasoline”. Reformulated 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.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines that
have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gasoline
contains a higher level of detergents to further
aide in minimizing engine and fuel system
deposits. When available, the usage of TOP
TIER Detergent Gasoline is recommended. Visit
www.toptiergas.com for a list of TOP TIER Detergent
Gasoline retailers.
Indiscriminate use of fuel system cleaning agents should
be avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and
diaphragm materials.
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.

GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol
are not the responsibility of the manufacturer and may
void the New Vehicle Limited Warranty.
DO NOT USE E-85 IN NON-FLEX FUEL
V
EHICLES
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline
containing up to 15% ethanol (E-15). Use of gasoline with
higher ethanol content may void the New Vehicle Limited
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 drivability.
 Increased risk for fuel system component corrosion.
CNG AND LP FUEL SYSTEM
M
ODIFICATIONS
Modifications that allow the engine to run on Compressed
Natural Gas (CNG) or Liquid Propane (LP) may result in
damage to the engine, emissions, and fuel system
components. Problems that result from running CNG or LP
are not the responsibility of the manufacturer and may
void the New Vehicle Limited Warranty.
METHYLCYCLOPENTADIENYL
M
ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
MMT is a manganese-containing metallic additive that is
blended into some gasolines to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug life
and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content of gasoline may not be indicated on the
gasoline pump; therefore, you should ask the gasoline
retailer whether the gasoline contains MMT. MMT is
prohibited in Federal and California reformulated
gasoline.
FUEL SYSTEM CAUTIONS
NOTE:Intentional tampering with the emissions control system
can result in civil penalties being assessed against you.
CAUTION!
DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15).
Use of these blends may result in starting and
drivability problems, damage critical fuel system
components, cause emissions to exceed the applicable
standard, and/or cause the Malfunction Indicator Light
to illuminate. Please observe pump labels as they
should clearly communicate if a fuel contains greater
than 15% ethanol (E-15).
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:

The use of leaded gasoline 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 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 meth -
anol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or addi -
tives is not the responsibility of the manufacturer
and may void or not be covered under the New
Vehicle Limited Warranty.
