If a low tire pressure condition is detected, the TPM system will display the CHECK TIRE PRESSURE warning message on the DIC and, at the same time, illuminate the low tire pressure warning symbol, on the instrument panel cluster. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. When the low tire pressure telltale is illuminated, one or more of your tires is significantly under-inflated. Your Vehicle on page 4-32 for an example of the tire and loading information label and its location on your vehicle. Also see Inflation - Tire Pressure on page 5-65. 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 5-70 and Tires on page 5-57. Notice: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors. TPM Sensor Identification Codes Each TPMS sensor has a unique identification code. Any time you replace one or more of the TPMS sensors or rotate your vehicle's tires, the identification codes will need to be matched to the new tire/wheel position. The sensors are matched, to the tire/wheel positions, in the following order: driver's side front tire, passenger's side front tire, passenger's side rear tire, and driver's side rear tire using a TPMS diagnostic tool. See your GM dealer for service. The TPMS sensors may also be matched to each tire/wheel position by increasing or decreasing the tire's air pressure. If using this method to match TPMS sensors, the complete procedure outlined below must be performed within 15 minutes of the vehicle being stationary. You should stop and check your tires as soon as possible, and inflate them to the proper pressure. 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. A Tire and Loading Information Label, attached to your vehicle, shows the size of your vehicle's original equipment tires and the correct inflation pressure for your vehicle's tires when they are cold.
