244 SERVICING AND MAINTENANCE
Tire Repair
If your tire becomes damaged, it may be
re
paired 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 a ¼ of an
inch (6 mm).
Consult an authorized tire dealer for tire repairs
a n
d additional information.
Damaged Run Flat tires, or Run Flat tires that
h a
ve 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
r a
pid 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
driving with underinflated tire condition, please
replace the Tire Pressure Monitoring (TPM)
sensor as it is not designed to be reused when
driven under run flat mode 14 psi (96 kPa)
condition.
NOTE:
TPM Sensor must be replaced after driving the
v e
hicle on a flat tire condition.
It is not recommended driving a vehicle loaded
a t
full capacity or to tow a trailer while a tire is in
the run flat mode.
Refer to “Tire Pressure Monitoring” in “Safety”
f o
r further information.
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.
Refer to “Freeing A Stuck Vehicle” in “In Case Of
E m
ergency” for further information.
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)
f o
r more than 30 seconds continuously when
you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.

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
th
e tread grooves. They will appear as bands
when the tread depth becomes a 1/16 of an
inch (1.6 mm). When the tread is worn to the
t r
ead wear indicators, the tire should be
replaced.
Refer to “Replacement Tires” in this section for
f u
rther information.
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 pres -
sures can cause uneven wear patterns to
d e
velop 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
w h
en installing new tires due to wear and tear
in existing tires.
Keep dismounted tires in a cool, dry place with
a s
little exposure to light as possible. Protect
tires from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed. Refer to the paragraph
on “Tread Wear Indicators” in this section.
Refer to the Tire and Loading Information placard
o r
the Vehicle Certification Label for the size
designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the
original equipment tire sidewall.
See the Tire Sizing Chart example found in the
“T
ire Safety Information” section of this manual
for more information relating to the Load Index
and Speed Symbol of a tire.

2 — New Tire
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 MAINTENANCE 251
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 rotation
o f
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 Plan” for the proper
m a
intenance intervals. The reasons for any
rapid or unusual wear should be corrected prior
to rotation being performed.
The suggested Front Wheel Drive (FWD) rotation
m e
thod is the “forward cross” shown in the
following diagram. This rotation pattern does
not apply to some directional tires that must not
be reversed.

DEPARTMENT OF TRANSPORTATION
UNIFORM 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
on
e 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
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
co
ntrolled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.

258 TECHNICAL SPECIFICATIONS
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 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.
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
r e
commended. 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
de
tergents 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
a g
ents 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.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline
with oxygenates such as ethanol.
Problems that result from using gasoline
c o
ntaining more than 15% ethanol (E-15) or
gasoline containing methanol are not the
responsibility of the manufacturer and may void
or not be covered under New Vehicle Limited
Warranty.
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 driveability 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).
TECHNICAL SPECIFICATIONS 259
(Continued)
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 driveability.
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 or not be covered
under the New Vehicle Limited Warranty.
MMT IN GASOLINE
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic
additive that is blended into some gasoline 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 your
gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and
California reformulated gasoline.
FUEL SYSTEM CAUTIONS
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 performance and damage
the emissions control system.
An out-of-tune engine or certain fuel or igni -
tion malfunctions can cause the catalytic
c o
nverter to overheat. If you notice a
pungent burning odor or some light smoke,
your engine may be out of tune or malfunc -
tioning and may require immediate service.
C o
ntact an authorized dealer for service
assistance.
