2006 Cadillac STS-V Owner's Manual - Page 381

You will have one minute to match the first tire/wheel position, and five minutes overall, to match all four tire/wheel positions. If it takes longer than one minute, to match the first tire and wheel, or more than five minutes to match all four tire/wheel positions the matching process stops and you will need to start over. The TPM matching process is outlined below: 1. Set the parking brake. 2. Press the push-button ignition switch to OFF/ACC. 3. Using the Keyless Access transmitter, lock and unlock the vehicle's doors. 4. Press the lock and unlock buttons, at the same time, on the Keyless Access transmitter. A single horn chirp will sound, indicating that the TPMS system is ready, and the sensor matching process can begin. 5. Start with the driver's side front tire. 6. Remove the valve cap from the valve stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for five seconds, or until a horn chirp sounds. The horn chirp, which may take up to 30 seconds to sound, confirms that the sensor identification code has been matched to this tire position. To decrease the tire's air-pressure use the pointed end of the valve cap, a pencil-style air pressure gauge, or a key. 7. Proceed to the passenger's side front tire, and repeat the procedure in Step 6. 8. Proceed to the passenger's side rear tire, and repeat the procedure in Step 6. 9. Proceed to the driver's side rear tire, and repeat the procedure in Step 6. 10. After hearing the confirming single horn chirp for the driver's side rear tire, a double horn chirp will sound to signal the tire matching mode is no longer active. Press the push-button ignition switch to OFF/ACC. 11. Set all four tires to the recommended air pressure level as indicated on the tire and loading information label. 12. Put the valve caps back on the valve stems. The spare tire does not have a TPMS sensor. If you replace one of the road tires with the spare, the SERVICE TIRE MONITOR message will be displayed on the DIC screen. This message should go off once you re-install the road tire containing the TPM sensor. The SERVICE TIRE MONITOR message is also displayed when the TPMS system is malfunctioning. One or more missing or inoperable TPMS sensors will cause the SERVICE TIRE MONITOR message to be displayed. See your GM dealer for service. 5-69
