2004 Cadillac SRX Owner's Manual - Page 380

Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recommended inflation pressure as specified in the vehicle placard and owner's manual. The Certification/Tire label or the Tire and Loading Information Label (your vehicle's tire information placard) shows the size of your vehicle's original tires and the recommended cold inflation pressure for your vehicle's tire. See Inflation - Tire Pressure on page 5-68. For the location of the tire and loading information label, see Loading Your Vehicle on page 4-48. Your vehicle's TPM system 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. TPM Sensor Identification Codes Each TPM sensor has a unique identification code. Any time you replace one or more of the TPM sensors, the identification codes will need to be matched to the new tire/wheel position. Each tire/wheel position is matched, to a sensor, by increasing or decreasing the tire's air pressure. The sensors are matched, to the tire/wheel positions, in the following order: left front (LF), right front (RF), right rear (RR), and left rear (LR). 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. 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 TPM system is ready, and the sensor matching process can begin. Notice: Do not use a tire sealant if your vehicle is equipped with Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors. 5-70
