need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to
receive this information.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the Tire Pressure Moni-
toring Telltale Light off.
Service Tire Pressure System Warning
If a system fault is detected, the TPM 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 Tire Pressure Sys-
tem" 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 switch is cycled, this sequence
will repeat, providing the system fault still ex-
ists. If the system fault no longer exists, the
TPM Telltale Light will no longer flash, and the
"Service Tire Pressure 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:
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 materials 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 Compact 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 warn-
ing 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 pressure value and an "Inflate
to XX" message.
3. After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the “TPMS Tell-
tale Light” will flash on and off for 75 sec-
onds and then remain on solid. In addition,
the instrument cluster will display a “Service
Tire Pressure System” message for five sec-
onds and then display dashes (- -) in place of
the pressure value.
