264 STARTING AND OPERATING Base System - If Equipped 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 Monitor System (TPMS) consists of the following components: • Receiver Module • 4 Tire Pressure Monitoring Sensors • Tire Pressure Monitoring Telltale Light A tire pressure monitoring sensor is located in the spare wheel if the vehicle is equipped with a matching full size spare wheel and tire assembly. The matching full size spare tire can be used in place of any of the four road tires. The "Tire Pressure Monitoring Telltale Light" will illuminate in the instrument cluster, and an audible chime will be activated when one or more of the four active road tire pressures are low. The audible chime will sound once every ignition cycle for each condition that it detects. Should this occur, you should stop as soon as possible, check the inflation pressure of each tire on your vehicle, and inflate each tire to the vehicle's recommended cold tire pressure. The system will automatically update, and the "Tire Pressure Monitoring Light" will extinguish once the updated tire pressures have been received. The vehicle may need to be driven for up to 10 minutes above 15 mph (24 km/h) to receive this information. A low spare tire will not cause the "Tire Pressure Monitoring Telltale Light" to illuminate or the chime to sound.
