an audible chime will be activated and the
"Service Tire Pressure Monitoring System" text
message will display. If the ignition key is cycled,
this sequence will repeat providing the system
fault still exists. The Tire Pressure Monitoring
System Warning 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 fre-
quencies as the TPM sensors.
• Installing some form of aftermarket window
tinting that affects radio wave signals.
• Snow or ice around the wheels or wheel
housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM
sensors.
NOTE:
Your vehicle may be equipped with a compact
spare wheel and tire assembly.
• The compact spare tire does not have a tire
pressure monitoring sensor. Therefore, the
TPMS will not monitor the tire 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 igni-
tion key cycle, a chime will sound, the Tire
Pressure Monitoring System Warning Light and
the Low inflation pressure left or right front /
rear tire message will still turn ON due to the
low tire.
• However, after driving the vehicle for up to
20 minutes above 15 mph (24 km/h), the Tire
Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and then remain
on solid and the "Service Tire Pressure Moni-
toring System" message will be displayed.
• This occurs for each subsequent ignition key
cycle, a chime will sound and the Tire Pressure
Monitoring System Warning Light will flash on
and off for 75 seconds and then remain on solid
and the "Service Tire Pressure Monitoring Sys-
tem" message will be displayed.
• 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 update auto-
matically and the Tire Pressure Monitoring Sys-
tem Warning 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.
TPM System With (TFT) Tire Pressure Dis-
play Screen
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.
The TPMS consists of the following components:
• Receiver module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System mes-
sages, which display in the instrument cluster
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Pressure Warn-
ings
The Tire Pressure Monitoring System
Warning Light will illuminate in the in-
strument cluster and a chime will sound
when tire pressure is low in one or more of the
