Should a low tire condition occur on any of the four active
road tire(s), you should stop as soon as possible, and inflate
the low tire(s) that is in a different color on the graphic
display to the vehicle’s recommended cold tire pressure
displayed in the Inflate to XXX message.
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 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:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM sensors.
