372 STARTING AND OPERATING the max load inflation pressure (cold) values to switch the TPMS system to the max load inflation pressure (cold) low pressure warning threshold. If after pressing the tire light load inflation switch, and tire pressures are below the max load inflation pressure (cold) low pressure warning thresholds, the TPMS low pressure warning telltale light (located in the instrument cluster) will turn ON and a chime will sound. The tire pressures are now required to be inflated to the max load inflation pressure (cold) values described on the Tire and Loading Information label. The Tire and Loading Information label is located on the drivers side B-pillar. If the tire light load inflation switch LED turns OFF, the TPMS has been reset and the TPMS is using the max load inflation pressure (cold) low pressure warning thresholds. Tire Pressure Monitor System Components 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 your tires regularly and to maintain the proper pressure. The Tire Pressure Monitoring System (TPMS) consists of the following components: • Receiver Module • Four Wheel Sensors • Two Trigger Modules (mounted in the front wheelwells) • Tire Light Load Inflation Switch (located in the instrument panel) • Tire Pressure Monitoring Telltale Light
