294 STARTING AND OPERATING by a graphic display, with "- -" in place of the pressure value(s) indicating which Tire Pressure Monitoring Sensor(s) is not being received. NOTE: Your system can be set to display pressure units in PSI, kPA or BAR. If the ignition key is cycled, this sequence will repeat, providing the system fault still exists. If the system fault no longer exists, the "Tire Pressure Monitoring Telltale Light" will no longer flash, the CHECK TPM SYSTEM text message will not be present, and a pressure value will be displayed instead of dashes. NOTE: Your vehicle is either equipped with the standard compact spare tire or an optional non-matching full size spare tire. Both of these spare tires do not have a tire pressure monitoring sensor. Therefore, they will not be monitored by the Tire Pressure Monitor System (TPMS). In the event that the non-matching full size or compact spare tire is swapped with a low pressure road tire, the next ignition key cycle will still show the "Tire Pressure Monitoring Telltale Light" 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.
