284SERVICING AND MAINTENANCE

Inflation pressures specified on the placard are
always “cold tire inflation pressure”. Cold tire
inflation pressure is defined as the tire pressure
after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after
sitting for a minimum of three hours. The cold tire
inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.

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 a 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 driving with underinflated tire
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.

condition, please replace the TPMS sensor as it is
not designed to be reused when driven under Run
Flat mode 14 psi (96 kPa) condition.
NOTE: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.
See the Tire Pressure Monitoring System section
for more 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.
For further information Ú page 242.
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 Ú page 286.
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
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.
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 — Worn Tire
2 — New TireWARNING!

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.

298TECHNICAL SPECIFICATIONS
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.
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 or not be covered under 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 or not be covered under
the 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 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).
