330 STARTING AND OPERATING the pressure value(s) indicating which tire pressure monitoring sensor(s) is not being received. 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 ЉCHECK TPM SYSTEMЉ text message will not be present, and a pressure value will be displayed instead of dashes. A system fault can occur by any of the following scenarios: 1) Jamming due to electronic devices or driving next to facilities emitting the same radio frequencies as the TPM sensors;. 2) Installing some form of aftermarket window tinting that affects radio wave signals; 3) Lots 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: Your vehicle is equipped with a non-matching full size spare wheel and tire assembly. 1. This spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not monitor the tire pressure in the spare tire. 2. If you install the full size spare tire 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 still turn ON. In addition, the graphic in the EVIC will still display a flashing pressure value. 3. However, after driving the vehicle for up to 10 minutes above 15 mph (25 km/h), the TPM Telltale Light will flash on and off for 75 seconds and then remain on solid. The EVIC will display a "CHECK TPM SYSTEM" message for three seconds and then display dashes (- - -) in place of the pressure value. 4. For each subsequent ignition key cycle, a chime will sound and the TPM Telltale Light will flash on and off for 75 seconds and then remain on solid. The EVIC will
