Tire Pressure Monitor System The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. If your vehicle has this feature, sensors are mounted on the tire and wheel assembly. The TPMS sensors transmit tire pressure readings 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. If your vehicle has the base audio system, the Driver Information Center (DIC) displays TPMS warnings and messages on the radio's display screen. See System Controls on page 3-53 and DIC Warnings and Messages on page 3-61 for additional information and details about the DIC operation and displays. If your vehicle has the Navigation system, TPMS warnings and messages are displayed on the message center screen, located inside the tachometer. See Message Center (CTS-V) on page 3-47 for information about the message center operation and displays. If a low tire pressure condition is detected, the TPMS will display the Check Tire Pressure message on the DIC or message center 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. 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. The Tire and Loading Information label shows the size of your vehicle's original tires and their recommended cold inflation pressures. See Loading Your Vehicle on page 4-32, for the location of the tire and loading information label. Also see Inflation - Tire Pressure on page 5-66. 5-69
