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:
•
Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
•
Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
•
Accumulation of snow or ice around the wheels or
wheel housings.
•
Using tire chains on the vehicle.
•
Using wheels/tires not equipped with TPM sensors.
Vehicles With Non Matching Full Size Spare Or Compact
Spare
•
The non matching full size spare or compact spare tire
does not have a TPM sensor. Therefore, the TPMS will
not monitor the pressure in the non matching full size
spare or compact spare tire.
•
If you install the non matching full size spare or 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 TPM Telltale Light and a “LOW TIRE”
message will remain ON and a chime will sound. In
addition, the graphic in the instrument cluster will still
display a pressure value in a different color.
•
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 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.
•
Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the non matching
full size spare or compact spare, the TPMS will update
automatically. In addition, the TPM Telltale Light will
turn OFF and the graphic in the instrument cluster will
display a new pressure value instead of dashes (- -). 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.
