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.
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 “TPM
Telltale Light”. Driving the vehicle may cause the tire
pressure to rise to approximately 27 psi (186 kPa), but the
“TPM Telltale Light” will still be ON. In this situation, the
“TPM Telltale Light” will turn OFF only after the tires are
inflated to the vehicle’s recommended cold placard pres-
sure 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 moisture and dirt from entering the valve
stem, which could damage the TPM sensor.
454 STARTING AND OPERATING

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 “TPM Telltale Light”. •
Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Premium 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.
5
STARTING AND OPERATING 455

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 Driver
Information Display (DID), and
• TPM Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “TPM Telltale Light” will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four active road
tires. In addition, the Drivers Information Display (DID)
will display a “LOW TIRE” message and a graphic
showing the pressure values of each tire with the low tire
pressure values shown in a different color.
Should this occur, you should stop as soon as possible
and inflate all of the tires with a low pressure condition
(those shown in a different color in the DID graphic) to
Tire Pressure Monitor Display

the vehicle’s recommended cold placard pressure infla-
tion value. Once the system receives the updated tire
pressures, the system will automatically update, the
graphic display in the DID will return the pressure values
shown to their original color, and the “TPM Telltale
Light” will turn off. The vehicle may need to be driven
for up to 10 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
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.
Service TPMS Warning
If a system fault is detected, the “TPM 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
DID will display a SERVICE TPM SYSTEM message fora minimum of five seconds 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 “TPM Telltale Light” will no longer
flash, and the
SERVICE TPM SYSTEM 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.
5
STARTING AND OPERATING 457

4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles With Compact Spare
1. The compact spare tire does not have a TPM sensor.Therefore, the TPMS will not monitor the pressure in
the compact spare tire.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition switch cycle, the
“TPM Telltale Light” will remain ON and a chime will
sound. In addition, the graphic in the DID will still
display the low pressure values in a different color.
3. After driving the vehicle for up to 10 minutes above 15 mph (24 km/h), the “TPM Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the DID will display a SERVICE TPMSYSTEM
message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value.
4. For each subsequent ignition switch cycle, a chime will sound, the “TPM Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the DID
will display a SERVICE TPM SYSTEM message for a
minimum of five seconds and then display dashes (- -)
in place of the pressure value.
5. 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
“TPM Telltale Light” will turn OFF and the graphic in
the DID will display a new pressure value instead of
dashes (- -), as long as no tire pressure is below the
low-pressure warning limit in any of the four active
road tires. The vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.
