message 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 TPM 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 TPM 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
and the TPM Telltale Light and
LOW TIREmessage will
turn ON.
3. Driving the vehicle for up to 20 minutes above 15 mph
(24 km/h) will turn off the TPM Telltale Light and LOW
TIRE message as long as no tire pressure is below the
low-pressure warning limit in any of the four active road
tires.
404 STARTING AND OPERATING
Page 407 of 566

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 warning
limit, upon the next ignition switch cycle, a chime will
sound and the TPM Telltale Light andLOW TIRE
message will turn ON.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the LOW TIREmessage will turn off
and the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid.
4. For each subsequent ignition switch cycle, a chime will
sound and the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid. 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 and the TPM 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. 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.
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.5
STARTING AND OPERATING 405
Page 408 of 566
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
TPM Telltale Light to illuminate or the chime to sound.
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 EVIC will display a
LOW TIRE
message and a graphic showing the pressure values of
each tire with the low tire pressure values flashing.
406 STARTING AND OPERATING
Page 410 of 566

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 theSERVICE 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.
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 related to an incorrect sensor location fault is
detected. In this case, the SERVICE TPM SYSTEM
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
the SERVICE 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 TPM Telltale Light will turn ON. In addition, the
