Tire Pressure Monitor System Your vehicle may have this feature. 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 for the compact spare tire and wheel. Tire pressure readings are sent to a receiver located in the vehicle once every 60 seconds while the vehicle is being driven, and once every 60 minutes if the vehicle is stationary for more than 15 minutes. Using the Driver Information Center (DIC), tire pressure levels can be viewed by the driver. For additional information and details about the DIC operation and displays see System Controls on page 3-48 and DIC Warnings and Messages on page 3-57. 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, on the instrument panel cluster. 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 Tire and Loading Information Label (your vehicle's tire information placard) shows the size of your vehicle's original tires and their recommended cold inflation pressures. See Loading Your Vehicle on page 4-45, for the location of the tire and loading information label. Also see Inflation - Tire Pressure on page 5-58. 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 5-63 and Tires on page 5-52. 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. 5-61
