NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
The TPIS consists of the following components:
• Receiver module
• Four TPM sensors (Single Rear Wheel [SRW] applica-
tions)
• Six TPM sensors (Dual Rear Wheel [DRW] applications)
• Pressure display in the instrument cluster display.
The TPIS system will display all four (Single Rear Wheel
[SRW] applications) or six (Dual Rear Wheel [DRW] appli-
cations) tire pressure values in the instrument cluster
display.
If a system fault is detected, 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 to indicate which sensor 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
SERVICE TPM SYSTEM message will
no longer be displayed, 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.
