330 STARTING AND OPERATING If the ignition key is cycled, this sequence will repeat, providing the system fault still exists. If the system fault no longer exists, the TPM Telltale Light will no longer flash, and the ЉCHECK TPM SYSTEMЉ message will no longer display, and a pressure value will display in place of the dashes. A system fault can occur due to any of the following: 1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as the TPM sensors. 2. Installing aftermarket window tinting that contains materials that may block radio wave signals. 3. Accumulation of snow or ice around the wheels or wheel housings. 4. Using tire chains on the vehicle. 5. Using wheels/tires not equipped with TPM sensors. NOTE: Vehicles with Full Size Spare 1. The matching full size spare wheel and tire assembly has a TPM sensor that can be monitored by the TPMS. 2. If you install the full size spare in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition key cycle, a chime will sound and the TPM Telltale Light will turn ON. In addition, the EVIC will display a low pressure message and a graphic showing the low tire pressure value flashing. 3. After driving the vehicle for up to 20 minutes above 15 mph (25 km/h) the TPM Telltale Light will turn OFF, as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires.
