2008 Dodge Nitro Owner Manual - Page 300

300 STARTING AND OPERATING vehicle may need to be driven for up to 10 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information. Check TPMS Warning When a system fault is detected, the Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds and then remain on solid. The system fault will also sound a chime. If the ignition key is cycled, this sequence will repeat, providing the system fault still exists. The Tire Pressure Monitoring Telltale Light will turn off when the fault condition no longer exists. A system fault can occur due to any of the following: 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: Vehicles with Full Size Spare 1. The matching full size spare wheel and tire assembly has a tire pressure monitoring 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. 3. Driving the vehicle for up to 10 minutes above 15 mph (25 km/h) will turn off the TPM Telltale Light, as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires.
