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 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. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting that
affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel hous-
ings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
NOTE:
• The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not monitor
the 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 ignition switch cycle, the “Tire
Pressure Monitoring Telltale Light” will remain on and a
chime will sound. In addition, the graphic in the instru-
ment cluster will still display a pressure value in a
different color.
• After driving the vehicle for up to 10 minutes above
15 mph (24 km/h), the “Tire Pressure Monitoring Tell-
tale Light” will flash on and off for 75 seconds and then
remain on solid. In addition, the instrument cluster will
display a ⬙SERVICE TPM SYSTEM⬙ message for a mini-
mum of five seconds and then display dashes (- -) in
place of the pressure value.
• For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds and then remain on solid,
and the instrument cluster will display a ⬙SERVICE TPM
SYSTEM⬙ message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value.
