SERVICE THEFT SYSTEM This message displays if there is a problem with the theft-deterrent system programmed in the key. A fault has been detected in the system which means that the system is disabled and it is not protecting the vehicle. The vehicle usually restarts; however, you may want to take the vehicle to your dealer before turning off the engine. See Keys on page 84 for information on the PASS-Key® III system. This message displays only while the ignition is in RUN. A chime sounds for two seconds while this message is displayed. Press the set/reset button to acknowledge this message and to clear it from the screen. This message continues to display if it has not been acknowledged when the engine is turned off. It also re-displays for three 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. 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 20 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.
