WHEELS AND TIRES If you have a flat tire, see "Flat tire" in 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. 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 Monitoring System (TPMS)" in the "Starting and driving" section, and "Flat tire" in the "In case of emergency" section. 8-34 Maintenance and do-it-yourself WDI0343 WDI0320 Trunk light High-mounted stoplight (rear window)
