Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. A Tire and Loading Information label, attached to your vehicle, shows the size of your vehicle's original equipment tires and the correct inflation pressure for your vehicle's tires when they are cold. See Loading Your Vehicle on page 317, for an example of the Tire and Loading Information label and its location on your vehicle. Also see Inflation - Tire Pressure on page 408. Your vehicle's TPMS system can warn you about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection and Rotation on page 414 and Tires on page 400. Notice: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors. The TPMS will not function properly if one or more of the TPMS sensors are missing or inoperable. If the system detects a missing or inoperable sensor, an error message SERVICE TIRE MONITOR SYSTEM appears on the DIC display. If you have replaced a tire/wheel assembly without transferring the TPMS sensors, the error message displays. Once you re-install the TPMS sensors, the error message should go off. See your dealer for service if all TPMS sensors are installed and the error message comes on and stays on. 411
