check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are underinflated.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap (if equipped). This
will prevent moisture and dirt from entering the
valve stem, which could damage it.
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 mi
(1.6 km) after a three-hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure 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
12ÉF (7ÉC) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the winter.
Example: If garage temperature = 68ÉF (20ÉC) and the
outside temperature = 32ÉF (0ÉC) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12ÉF (7ÉC) 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
within posted speed limits. Where speed limits or condi-
tions 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 opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle at or above
maximum load is dangerous. The added strain on
your tires could cause them to fail. You could have a
serious accident. Don't drive a vehicle loaded to the
maximum capacity at continuous speeds above 75
mph (120 km/h).
Radial-Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial tires in sets of four. Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized dealer for radial tire repairs.
210 STARTING AND OPERATING
Page 213 of 358
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle's wheels above 35 mph (55 km/h).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle's wheels faster than 35
mph (55 km/h) 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.
STARTING AND OPERATING 211

Page 214 of 358
These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the indicators appear in
two or more adjacent grooves, the tire should be re-
placed.
Many states have laws requiring tire replacement at this
point.
Life Of Tire
The service life of a tire is dependent upon various
factors including but not limited to:
²Driving style
²Tire pressure
²Distance driven
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 an accident resulting
in serious injury or death.
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.

Page 215 of 358
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 pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. (Refer to the paragraph on
ªTread Wear Indicatorsº). Refer to the ªTire and Loading
Informationº placard for the size designation of your
tires. The service description and load identification will
be found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.WARNING!
²Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspension
dimensions and performance characteristics, result-
ing in changes to steering, handling, and braking of
your vehicle. This can cause unpredictable handling
and stress to steering and suspension components.
You could lose control and have an accident resulting
in serious injury or death. Use only the tire and wheel
sizes with load ratings approved for your vehicle.
²Never use a tire with a smaller load index or capacity
than what was originally equipped on your vehicle.
Using a tire with a smaller load index could result in
tire overloading and failure. You could lose control
and have an accident.
²Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire
failure and loss of vehicle control.

CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer
readings.
Alignment And Balance
Poor suspension alignment may result in:
²Fast tire wear
²Uneven tire wear, such as feathering and one-sided
wear
²Vehicle pull to the left or right
Tires may also cause the vehicle to pull left or right.
Alignment will not correct this problem. See your autho-
rized dealer for proper diagnosis.Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
TIRE PRESSURE MONITOR SYSTEM
Each tire should be checked monthly when cold and
inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire infla-
tion pressure label. (If your vehicle has tires of a different
size than the size indicated on the vehicle placard or tire
inflation pressure label, you should determine the proper
tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure indicator light
when one or more of your tires is significantly under-
inflated. When the low tire pressure indicator light
illuminates, you should stop and check your tires as soon
214 STARTING AND OPERATING
Page 217 of 358
as possible, and inflate them to the proper pressure,
Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-
inflation also reduced fuel efficiency and tire tread life,
and may affect the vehicle's handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure indicator light.
The TPMS uses wireless technology to monitor tire
pressure levels. Sensors mounted to each wheel as part of
the valve stem transmit tire pressure readings to a
receiver located inside the vehicle.NOTE:The TPMS can inform you about a low tire
pressure condition, but it does not replace normal tire
maintenance. The TPMS is not intended to provide you
with notification of rapid tire pressure loss.
STARTING AND OPERATING 215

Page 218 of 358
CAUTION!
The TPM system is designed to monitor your tire
pressure and will not function as a tire pressure
gauge. After adjusting the air pressure in a tire, there
will be a delay before the system updates the display.
The system will automatically update and the Tire
Pressure Monitoring Indicator Light will turn off,
once the system receives the updated tire pressures.
The vehicle needs to be driven above 20 mph in order
for the TPMS to receive this information.The TPMS will cause the indicator light in the instrument
cluster to illuminate whenever the pressure in one tire
falls 25% below the recommended pressure shown on the
vehicle's tire label.
The TPMS will cause the indicator light to flash for
approximately one minute and then remain continuously
illuminated whenever the system detects a TPMS mal-
function.
NOTE:The pressure in your tires changes with tem-
perature. A significant decrease in temperature could
reduce cold inflation pressure below the TPMS set-point.
For example, tires inflated to the proper cold inflation
pressure on a warm day or in a warm garage could
illuminate the TPMS indicator light on the following day
216 STARTING AND OPERATING

if the temperature is very cold.ALWAYScheck the
pressure in your tires if the TPMS indicator light is
illuminated.CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. The TPMS pressures
have been established for the tire size equipped on
your vehicle. Undesirable operation or sensor dam-
age may result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not
use aftermarket tire sealant or balance beads, as
damage to the sensors may result.
NOTE:The standard TIREFIT system (refer to What To
Do In Emergencies for more information) is specifically
designed to operate in conjunction with the TPMS, and
will not damage the sensors.

If your tire pressure is low, you should correct your tire
inflation pressure as soon as possible and inspect all of
your tires. Low tire pressure will cause the tire pressure
light to illuminate. They will remain on for the rest of the
driving cycle, or until the tire pressure is corrected. If the
TPMS indicator light remains illuminated after the tire
pressure has been corrected, see your authorized dealer.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure indicator light.
When the system detects a malfunction, the indicator
light will flash for approximately one minute and then
remain continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction indicator is
illuminated, the system may not be able to detect or
signal low tire pressure as intended. TPMS malfunctionsmay occur for a variety of reasons, including the instal-
lation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction indicator light after
replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function properly.
NOTE:Changes and modifications not expressly ap-
proved by the party responsible for compliance could
void the user's authority to operate the equipment.
