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 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 (26 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 "Monitor, climate, audio, phone 8-32 Maintenance and do-it-yourself and voice recognition systems" section, "Tire Pressure Monitoring System (TPMS)" in the "Starting and driving" section, and "Flat tire" in the "In case of emergency" section. Tire inflation pressure Check the tire pressures (including the spare) often and always prior to long distance trips. The recommended tire pressure specifications are shown on the F.M.V.S.S./C.M.V.S.S. certification label or the Tire and Loading Information label under the "Cold Tire Pressure" heading. The Tire and Loading Information label is affixed to the driver side center pillar. Tire pressures should be checked regularly because: ● Most tires naturally lose air over time. ● Tires can lose air suddenly when driven over potholes or other objects or if the vehicle strikes a curb while parking. The tire pressures should be checked when the tires are cold. The tires are considered COLD after the vehicle has been parked for 3 or more hours, or driven less than 1 mile (1.6 km) at moderate speeds. Incorrect tire pressure, including under inflation, may adversely affect tire life and vehicle handling.
