Tire Pressure Monitor System The Tire Pressure Monitor (TPM) system uses radio and sensor technology to check tire pressure levels. If your vehicle has this feature, sensors are mounted on each tire and wheel assembly, except the spare tire. The TPM sensors transmit tire pressure readings to a receiver located in the vehicle. When a low tire pressure condition is detected, the TPM system will display the CHECK TIRE PRESSURE warning message on the Driver Information Center (DIC); and at the same time illuminate the low tire pressure warning symbol. For additional information and details about the DIC operation and displays see DIC Operation and Displays on page 3-56 and DIC Warnings and Messages on page 3-68. When the tire pressure monitoring system warning light is lit, one or more of your tires is significantly under-inflated. You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the vehicle's tire information placard. 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 5-71. For the location of the tire and loading information label, see Loading Your Vehicle on page 4-58. 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. 5-72
