2007 Jeep Patriot Owner Manual - Page 300

STARTING AND OPERATING 299 Display Settings • Your system can be set to display pressure units in PSI, kPa, or BAR. NOTE: These display settings may not be available due to Regulatory Authorities. In this case, the display will only show approved units. NOTE: If your vehicle is equipped with a compact spare wheel and tire assembly that does not have a tire pressure monitoring sensor. Therefore, it will not be monitored by the Tire Pressure Monitor System (TPMS). In the event that the compact spare tire is swapped with a low pressure road tire, the next ignition key cycle will still show the "Tire Pressure Monitoring Lamp" to be ON, a chime to sound, and the Electronic Vehicle Information Center (EVIC) will still show the low tire pressure value flashing on the graphic display. However, driving the vehicle for up to 10 minutes above 15 mph (25 km/h) will display a "CHECK TPM SYSTEM" text message on the EVIC. This text message will then be followed by a graphic, with "- -" in place of the flashing low pressure value. For every subsequent key cycle, the "Tire Pressure Monitoring Lamp" will be ON, a chime will sound, a "CHECK TPM SYSTEM" text message will be display in the EVIC, and the graphic display will have "- -" in place of the pressure value of the spare tire location. Once the original road tire has been properly repaired, and put back onto the vehicle in place of the compact spare tire. The TPMS will update the graphic display on the EVIC with a new tire pressure value instead of "- -", and the "Tire Pressure Monitoring Lamp" will be OFF as long as none of the road tire(s) are below the low pressure warning threshold. The vehicle may need to be driven for up to 10 minutes above 15 mph (25 km/h) to receive this information. 5
