Your vehicle's TPMS can alert you about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection and Rotation on page 5-72 and Tires on page 5-58. Notice: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors. The TPM matching process is outlined below: 1. Set the parking brake. 2. Turn the ignition switch to ON with the engine off. 3. Using the Remote Keyless Entry (RKE) transmitter, lock and unlock the vehicle's doors. 4. Press the lock and unlock buttons, at the same time, on the RKE 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, 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 gage, 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. TPMS Sensor Identification Codes Each TPMS sensor has a unique identification code. Any time you replace one or more of the TPMS sensors or rotate the tires, the identification codes will need to be matched to the new tire and wheel position. The sensors are matched, to the tire and wheel positions, in the following order: left front (LF), right front (RF), right rear (RR), and left rear (LR) using a TPMS diagnostic tool. See your GM dealer for service. The TPMS sensors may also be matched to each tire and wheel position by increasing or decreasing the tire's air pressure. When increasing tire pressure do not exceed the maximum inflation pressure indicated on the tire's sidewall. You will have two minutes to match the first tire and wheel position, and five minutes overall, to match all four tire and wheel positions. If it takes longer than two minutes, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions the matching process stops and you will need to start over. 5-70
