NOTE: When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light 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
When a system fault is detected, the “Tire Pressure Moni-
toring Telltale Light” will flash on and off for 75 seconds
and then remain on solid. The system fault will also sound
a chime. In addition, 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 to indicate which sensor is not being
received.
If the ignition key 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:
• Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
• Installing some form of aftermarket window tinting that
affects radio wave signals.
•
Lots of snow or ice around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare or Non-Matching Full Size
Spare
1. The compact spare tire or non-matching full size does
not have a tire pressure monitoring sensor. Therefore,
the TPMS will not monitor the pressure in the compact
spare tire.
2.
If you install the compact or non-matching full size spare
tire in place of a road tire that has a pressure below the
low-pressure warning limit, upon the next ignition key
cycle, the “TPMS Telltale Light” will remain on and a chime
will sound. In addition, the graphic in the instrument
cluster will still display a different color or highlighted
pressure value and the “Inflate to XX” message.
