374 STARTING AND OPERATING 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 due to the low tire. 3. However, after driving the vehicle for up to 20 minutes above 15 mph (25 km/h), the "TPM Telltale Light" will flash on and off for 75 seconds and then remain on solid. 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. 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 and 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. The vehicle may need to be driven for up to 20 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information.
