Tire Pressure Monitor (TPM) System

The Tire Pressure Monitoring 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.|

The TPMS checks the pressure and temperature of the tires at all times sending the necessary information via the CAN. In particular, it activates signalling in the instrument panel if the inflation pressure is too low in one or more of the tires or if there is a puncture. The system comprises a control unit and four transmission sensors located in the tire on the wheel rim which send signals to four receiver aerials. At key-on, the control unit conducts an initial check: when the vehicle moves, the sensors measure the pressure and then make a transmission to indicate the initial status.|

The TPMS will warn the driver of a low tire pressure if the tire pressure falls below the low pressure warning limit for any reason, including low temperature effects, or natural pressure loss through the tire.

CAUTION: The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures and warnings have been established for the tire size equipped on the vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. Aftermarket wheels can cause sensor damage. Using aftermarket tire sealants may cause the Tire Pressure Monitoring System (TPMS) sensor to become inoperable.
