WHEELS AND TIRES If you have a flat tire, see the "In case of emergency" section of this manual. TIRE PRESSURE Tire pressure monitoring system (TPMS) This vehicle is equipped with the Tire Pressure Monitoring System (TPMS). It monitors tire pressure of all tires except the spare. When the low tire pressure warning light is lit, one or more of your tires is significantly under-inflated. If equipped, the system also displays pressure of all tires (except the spare tire) on the display screen by sending a signal from a sensor that is installed in each wheel. The TPMS will activate only when the vehicle is driven at speeds above 16 MPH (25 km/h). Also, this system may not detect a sudden drop in tire pressure (for example a flat tire while driving). For more details, refer to "Low tire pressure warning light" in the "Instruments and controls" section, "Tire pressure information" in the "Display screen, heater, air 8-30 Maintenance and do-it-yourself WDI0411 License plate light LDI0410 Rear combination light
