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 maintenance
schedule is highly recommended.
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. 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.
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 manu-
facturer 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 Indicator”. Refer to the Tire and Loading Information
placard or 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 equip-
ment tire sidewall. See the Tire Sizing Chart example found
in the “Tire Safety Information” section of this manual for
more information relating to the Load Index and Speed
Symbol of a tire.
It is recommended to replace the two front tires or two rear
tires as a pair. Replacing just one tire can seriously affect
your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match those of the
original wheels.

vehicle’s tires. The tire pressure will also increase as the
vehicle is driven - this is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning thresh-
old for any reason, including low temperature effects, or
natural air pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended cold
tire placard pressure. Once the low tire pressure warning
has been illuminated, the tire pressure must be increased to
the recommended cold tire placard pressure in order for
the “Tire Pressure Monitoring Telltale Light” to be turned
off.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
The system will automatically update and the “Tire Pres-
sure Monitoring Telltale Light” will extinguish once the
updated tire pressures have been received. NOTE:
The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this informa-
tion.
For example, your vehicle may have a recommended cold
(parked for more than three hours) tire placard pressure of
35 psi (241 kPa). If the ambient temperature is 68°F (20°C)
and the measured tire pressure is 30 psi (207 kPa), a
temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 26 psi (179 kPa). This tire
pressure is sufficiently low enough to turn on the “Tire
Pressure Monitoring Telltale Light.” Driving the vehicle
may cause the tire pressure to rise to approximately 30 psi
(207 kPa), but the “Tire Pressure Monitoring Telltale Light”
will still be on. In this situation, the “Tire Pressure Moni-
toring Telltale Light” will turn off only after the tires have
been inflated to the vehicle’s recommended cold tire plac-
ard pressure value.
CAUTION!
• The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size

equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.
• After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.
NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure. •
Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping
ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to maintain
correct tire pressure, using an accurate tire pressure
gage, even if under-inflation has not reached the level to
trigger illumination of the “Tire Pressure Monitoring
Telltale Light.”
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Base System
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the valve stem,
transmit tire pressure readings to the Receiver Module.
NOTE: It is particularly important for you to check the tire
pressure in all of your tires regularly and to maintain the
proper pressure.

The Basic TPMS consists of the following components:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
• TPMS Telltale Warning Light
Tire Pressure Monitoring Low Tire Pressure
Warnings
The “Tire Pressure Monitoring Telltale Light”
will illuminate in the instrument cluster, a “LOW
TIRE PRESSURE” message will display in the
instrument cluster, and an audible chime will be
activated when one or more of the four active road tire
pressures are low. Should this occur, you should stop as
soon as possible, check the inflation pressure of each tire on
your vehicle, and inflate each tire to the vehicle’s recom-
mended cold tire placard pressure value (located on the
placard label on the driver’s-side B-Pillar).
NOTE: When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order to
turn the Tire Pressure Monitoring Telltale Light off. The system will automatically update and the “Tire Pres-
sure Monitoring Telltale Light” will extinguish once the
updated tire pressures have been received.
NOTE:
The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this informa-
tion.
SERVICE TPM SYSTEM
The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and remain on solid when a system
fault is detected. The system fault will also sound a chime.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. The “Tire Pressure
Monitoring Telltale Light” will turn off when the fault
condition no longer exists. A system fault can occur with
any of the following scenarios:
• Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
• Installing some form of aftermarket window tinting that
affects radio wave signals.
• Accumulation of excessive snow and/or ice around the
wheels or wheel housings.
394 STARTING AND OPERATING

•Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare
• The compact spare tire (if equipped) does not have a
TPMS sensor. Therefore the TPMS will not monitor the
pressure in the compact spare tire.
• If you install the compact spare tire in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a chime will
sound, a “LOW TIRE PRESSURE” message will be
displayed and the “Tire Pressure Monitoring Telltale
Light” will turn on.
• After driving for up to 20 minutes above 15 mph
(24 km/h), the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid.
• For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds and then remain on solid.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare
tire, the TPMS will automatically update, and the “Tire Pressure Monitoring Telltale Light” will turn off as long
as no tire pressure is below the low-pressure warning
limit in any of the four active road tires.
NOTE: The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) for the TPMS to receive
this information.
Premium System
The TPMS uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pressure levels.
Sensors mounted to each wheel as part of the valve stem
transmit tire pressure readings to the Receiver Module.
NOTE: It is particularly important to regularly check and
maintain proper tire pressure in all the tires.
The Premium TPMS consists of the following components:
• Receiver Module
• Four TPMS Sensors
• Various TPMS messages, which display in the instru-
ment cluster, and graphics displaying tire pressures
• TPMS Telltale Warning Light

TPMS Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will illumi-
nate in the instrument cluster, and an audible chime will be
activated when one or more of the four active road tire
pressures are low. In addition, the instrument cluster will
display a “LOW TIRE” message and a graphic display of
the pressure value(s) with the low tire(s) flashing, high-
lighted or shown in a different color. AnInflate Tire to XX
message will also be displayed.
Should a low tire condition occur on any of the four active
road tire(s), you should stop as soon as possible, and inflate
the low tire(s) that is flashing, highlighted or shown in a
different color on the graphic display to the vehicle’s
recommended cold tire pressure value as shown in the
Inflate Tire to XX message.
NOTE: When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order to
turn the Tire Pressure Monitoring Telltale Light off.
The system will automatically update, the graphic display
of the pressure value(s) will stop flashing or return to their
original color and the “Tire Pressure Monitoring Telltale
Light” will extinguish once the updated tire pressure(s)
have been received. NOTE:
The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this informa-
tion.
SERVICE TPM SYSTEM Message
The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and remain on solid when a system
fault is detected. The system fault will also sound a chime.
The instrument cluster will display a “SERVICE TPM
SYSTEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with --in
place of the pressure value(s) indicating which TPMS
Sensor(s) is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the “Tire Pressure Monitoring Telltale Light”
will no longer flash, the “SERVICE TPM SYSTEM” mes-
sage will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following scenarios:
• Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
396 STARTING AND OPERATING

•Installing some form of aftermarket window tinting that
affects radio wave signals.
• Accumulation of excessive snow and/or ice around the
wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare
• The compact spare tire (if equipped) does not have a
TPMS. Therefore, the TPMS will not monitor the pres-
sure in the compact spare tire.
• If you install the compact spare tire in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the “Tire
Pressure Monitoring Telltale Light” will remain on, the
“LOW TIRE” message will be displayed, a chime will
sound, and the instrument cluster will still display a
flashing, highlighted or different color pressure value
and the Inflate Tire to XX message in the graphic
display.
• After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “Tire Pressure Monitoring Tell-
tale Light” will flash on and off for 75 seconds and then remain on solid. In addition, the instrument cluster will
display a “SERVICE TPM SYSTEM” message for a
minimum of five seconds and then display dashes (- -) in
place of the pressure value.
• For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds and then remain on solid,
and the instrument cluster will display a “SERVICE
TPM SYSTEM” message for a minimum of five seconds
and then display dashes (- -) in place of the pressure
value.
• Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“Tire Pressure Monitoring Telltale Light” will turn off
and the graphic in the instrument cluster will display a
new pressure value instead of dashes (- -), as long no tire
pressure is below the low pressure warning limit in any
of the four active road tires.
NOTE: The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) in order for the TPMS to
receive this information.

TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire assem-
blies that do not have TPMS Sensors, such as when
installing Winter wheel and tire assemblies on your ve-
hicle. To deactivate the TPMS, first, replace all four wheel
and tire assemblies (road tires) with tires not equipped
with Tire Pressure Monitoring (TPM) Sensors. Then, drive
the vehicle for 10 minutes above 15 mph (24 km/h). The
TPMS will chime, the “TPM Telltale Light” will flash on
and off for 75 seconds and then remain on and the
instrument cluster will display the “SERVICE TPM SYS-
TEM” message and then display dashes (--) in place of the
pressure values. Beginning with the next ignition switch
cycle, the TPMS will no longer chime or flash the TPM
telltale and display the “SERVICE TPM SYSTEM” message
in the instrument cluster display but dashes (--) will remain
in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPM
sensors. Then, drive the vehicle for up to 10 minutes above
15 mph (24 km/h). The TPMS will chime, the “TPM Telltale
Light” will flash on and off for 75 seconds and then turn
off, and the instrument cluster will display the “SERVICE
TPM SYSTEM” message. The instrument cluster will alsodisplay pressure values in place of the dashes. On the next
ignition switch cycle the “SERVICE TPM SYSTEM” mes-
sage will no longer be displayed as long as no system fault
exists.
