334 STARTING AND OPERATING 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 display a "CHECK TPM SYSTEM" message for three seconds, and then display dashes (- - -) in place of a pressure value. 5. Once you repair or replace the original road tire, and reinstall it on the vehicle in place of the full size spare tire, the TPMS will update automatically. In addition, the TPM Telltale Light will turn OFF and the graphic in the EVIC will display a new pressure value instead of dashes (- - -), as long as no tire pressure is below the lowpressure warning limit in any of the four active road tires.
