246 STARTING AND OPERATING NOTE: The compact spare tire (if so equipped) does not have a tire pressure monitoring sensor. Therefore, the TPMS will not monitor the pressure in the compact spare tire. However, if you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warning limit, the Tire Pressure Monitoring Telltale Light will remain ON and a chime will still sound each ignition key cycle. Once you repair or replace the original road tire, and reinstall it on the vehicle in place of the compact spare, the TPMS will update automatically and the Tire Pressure Monitoring Telltale Light will turn OFF, as long no tire pressure is below the low-pressure warning limit in any of the four active road tires. The vehicle may need to be driven for up to 10 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information. Premium 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 the tires on your vehicle regularly and to maintain the proper pressure. The TPMS consists of the following components: • Receiver Module • 4 Tire Pressure Monitoring Sensors • 3 Trigger Modules (mounted in three of the four wheel-wells) • Various Tire Pressure Monitoring System Messages, which display in the Electronic Vehicle Information Center (EVIC) • Tire Pressure Monitoring Telltale Light
