5. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for 10 seconds, then stop and listen for a single horn chirp. The single horn chirp should sound within 15 seconds, confirming that the sensor identification code has been matched to this tire and wheel position. If you do not hear the confirming single horn chirp, turn the ignition switch to LOCK and start over beginning with Step 2. To let air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage, or a key. 6. Proceed to the passenger's side front tire, and repeat the procedure in Step 5. 7. Proceed to the passenger's side rear tire, and repeat the procedure in Step 5. 8. Proceed to the driver's side rear tire, and repeat the procedure in Step 5. 9. After hearing the confirming horn chirp for the driver side rear tire, check to see if the TPMS low tire warning light and the DIC LOW TIRE messages have turned off. If yes, the TPMS sensors have been relearned. Turn the ignition switch to LOCK. If the low tire warning light and the DIC SERV TPM messages are on after completing Step 5 for the driver side rear tire, the sensor relearn process has not been successful. Turn the ignition switch to LOCK and repeat the matching process beginning with Step 2. 10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label. 11. Put the valve caps back on the valve stems. 390
