SERVICE TIRE MONITOR SYSTEM This message displays if a part on the Tire Pressure Monitor (TPM) system is not working properly. If you drive your vehicle while any of the four sensors are missing or inoperable, the warning comes on in about 10 minutes. A sensor would be missing, for example, if you put different wheels on your vehicle without transferring the sensors. If the warning comes on and stays on, there may be a problem with the TPM. See your dealer. This message displays while the ignition is in RUN. Press any of the DIC buttons to acknowledge this message and to clear it from the screen. This message continues to display for two seconds if it has not been acknowledged when the engine is turned off. It also re-displays for two seconds if the message has been acknowledged, but the condition still exists when the engine is turned off. If the condition still exists, the message re-appears when the engine is turned on.
