The system will automatically update, the graphic display
of the pressure value(s) will return to its original color and
the Tire Pressure Monitoring Telltale Light will extinguish
once the updated tire pressure(s) have been received. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
Service TPM System Warning
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 display 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 Tire Pressure
Monitoring 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⬙ message
will not be present, and a pressure value will be displayed
instead of dashes. A system fault can occur by any of the
following:
• Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM sensors.
• Installing some form of aftermarket window tinting that
affects radio wave signals.
• Lots of snow or ice around the wheels or wheel hous-
ings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
NOTE: There is no tire pressure monitoring sensor in the
spare tire. The TPMS will not be able to monitor the tire
pressure. If you install the 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, a chime will
sound, and the instrument cluster display will still display
