also increase as the vehicle is driven - this is normal and
there should be no adjustment for this increased pres-
sure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low-pressure warning
limit for any reason, including low temperature effects
and natural 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 the recommended
cold placard pressure. Once the low tire pressure warn-
ing (Tire Pressure Monitoring [TPM] Telltale Light) illu-
minates, you must increase the tire pressure to the
recommended cold placard pressure in order for the “Tire
Pressure Monitoring Telltale Light” to turn off. The
system will automatically update and the “Tire Pressure
Monitoring Telltale Light” will turn off once the system
receives the updated tire pressures. The vehicle may needto be driven for up to 20 minutes above 15 mph
(25 km/h) in order for the TPMS to receive this informa-
tion.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pressure
of 30 psi (207 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 27 psi (186 kPa),
a temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 23 psi (158 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
27 psi (186 kPa), but the “Tire Pressure Monitoring
Telltale Light” will still be ON. In this situation, the “Tire
Pressure Monitoring Telltale Light” will turn OFF only
after the tires are inflated to the vehicle’s recommended
cold placard pressure value.
514 STARTING AND OPERATING

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning 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. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPM 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
gauge, even if under-inflation has not reached the level
to trigger illumination of the “Tire Pressure Monitor-
ing Telltale Light.”

•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
The Tire Pressure Monitor System (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 the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
• Receiver module,
• Four TPM sensors, and
• TPM Telltale Light The matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor. The matching full size spare
can be used in place of any of the four road tires. The
TPMS will only monitor the pressure in the full size spare
when it is used in place of a road tire. Otherwise, a spare
with a pressure below the low-pressure limit will not
cause the “Tire Pressure Monitoring Telltale Light” to
illuminate or the chime to sound.
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE
PRESSURE” message will display in the EVIC, and a
chime will sound when tire pressure is low in one or
more of the four active road tires. An Inflate to XX
message will also be displayed. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
516 STARTING AND OPERATING

to the vehicle’s recommended cold placard pressure
value as shown in theInflate to XXmessage. Once the
system receives the updated tire pressures, the system
will automatically update and the “Tire Pressure Moni-
toring Telltale Light” and “LOW TIRE PRESSURE” mes-
sage will turn off. The vehicle may need to be driven for
up to 20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.
Service TPMS Warning
If a system fault is detected, the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for 75 seconds and
then remain on solid. 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 due to any of the following: 1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles with Full Size Spare
1. The matching full size spare wheel and tire assembly has a TPM sensor that can be monitored by the TPMS.
2. If you install the full size spare 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
5
STARTING AND OPERATING 517

displayed, and the “Tire Pressure Monitoring Telltale
Light” will turn ON. AnInflate to XXmessage will
also be displayed.
3. Driving the vehicle for up to 20 minutes above 15 mph (24 km/h) will turn off the “Tire Pressure Monitoring
Telltale Light” and “LOW TIRE PRESSURE” message,
as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires.
Premium System – If Equipped
The Tire Pressure Monitor System (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 the tires on your vehicle monthly
and to maintain the proper pressure. The TPMS consists of the following components:
•
Receiver module,
• Four TPM sensors,
• Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and
• TPM Telltale Light
The matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor. The full size spare can be
used in place of any of the four road tires. A spare with a
pressure below the low-pressure limit will not cause the
“Tire Pressure Monitoring Telltale Light” to illuminate or
the chime to sound.
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime
518 STARTING AND OPERATING

will sound when tire pressure is low in one or more of the
four active road tires. In addition, the EVIC will display
a “LOW TIRE PRESSURE” message for a minimum of
five seconds and a graphic showing the pressure values
of each tire with the low tire pressure values flashing or
in a different color. AnInflate to XXmessage will also be
displayed. Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition (those
flashing or in a different color in the EVIC graphic) to the
vehicle’s recommended cold placard pressure inflation
value as shown in the
Inflate to XXmessage. Once the
system receives the updated tire pressures, the system
will automatically update, the graphic display in the
EVIC will stop flashing or return to it’s original color, and
the “Tire Pressure Monitoring Telltale Light” will turn
off. 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.
Service TPMS Warning
If a system fault is detected, the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for 75 seconds and
then remain on solid. The system fault will also sound a
chime. In addition, the EVIC will display a SERVICE
TPM SYSTEM message for a minimum of five seconds
5
STARTING AND OPERATING 519

and then display dashes (- -) in place of the pressure
value to indicate which sensor 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, and theSERVICE TPMSYSTEM
message will no longer display, and a pressure
value will display in place of the dashes. A system fault
can occur due to any of the following:
1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
The EVIC will also display a SERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault possibly related to an incorrect sensor location fault
is detected. In this case, the SERVICE TPM SYSTEM
520 STARTING AND OPERATING

message is then followed with a graphic display with
pressure values still shown. This indicates that the pres-
sure values are still being received from the TPM sensors
but they may not be located in the correct vehicle
position. The system still needs to be serviced as long as
theSERVICE TPM SYSTEM message is displayed.
Vehicles with Full Size Spare
1. The matching full size spare wheel and tire assembly has a TPM sensor that can be monitored by the TPMS.
2. If you install the full size spare 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 and the “Tire Pressure Monitoring Telltale
Light” will turn ON. In addition, the EVIC will display
a “LOW TIRE PRESSURE” message and a graphic
showing the low tire pressure value flashing or in a
different color. An Inflate to XXmessage will also be
displayed. 3. After driving the vehicle for up to 20 minutes above
15 mph (25 km/h) the “Tire Pressure Monitoring
Telltale Light” will turn OFF and the pressure value
will be updated and stop flashing or return to it’s
original color, as long as no tire pressure is below the
low-pressure warning limit in any of the four active
road tires.
