2004 Cadillac Escalade EXT Owner's Manual - Page 378

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 (tire information placard) shows the size of your vehicle's original tires and the correct inflation pressure for your vehicle's tires when they are cold. See Inflation - Tire Pressure on page 5-70. For the location of the tire and loading information label, see Loading Your Vehicle on page 4-47. 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 5-74 and Tires on page 5-62. 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. TPM Sensor Identification Codes Each TPM sensor has a unique identification code. Any time you rotate your vehicle's tires or 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 and wheel positions the matching process stops and you will need to start over. The TPM sensor matching process is outlined below: 1. Set the Parking brake. 2. Turn the ignition switch to RUN with the engine off. 5-72
