The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels. Sensors mounted to each wheel as part of the valve stem transmit tire pressure readings to the receiver module.

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 TPMS consists of the following components:
• Receiver module,
• Four TPM sensors,
• Various TPMS messages, which display in the Electronic Vehicle Information Center (EVIC), and
• TPM Telltale Light

The matching full size spare wheel and tire assembly (if equipped) has a TPM sensor. The full size spare can be used in place of any of the four road tires. The TPMS will only monitor the pressure in the full size spare tire when it is used in place of a road tire. Otherwise, a spare with a pressure below the low-pressure limit will not cause the TPM Telltale Light to illuminate or the chime to sound.
