Vehicle Care 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. See Tire Pressure Monitor Operation on page 10￿77 for additional information. 10-77 Tire Pressure Monitor Operation This vehicle may have a Tire Pressure Monitor System (TPMS). The TPMS is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly, if the vehicle has one. The TPMS sensors monitor the air pressure in the tires and transmits the tire pressure readings to a receiver located in the vehicle. If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the tire loading information label. See Vehicle Load Limits on page 9￿12. A message to check the pressure in a specific tire displays in the DIC display screen. The low tire pressure warning light and the DIC warning message come at each ignition cycle until the tires are inflated to the correct inflation pressure. Using the Driver Information Center (DIC), tire pressure levels can be viewed. For additional information and details about the DIC operation and displays see Driver Information Center (DIC) on page 5￿28 and Tire Messages on page 5￿45. The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as the vehicle is driven. Federal Communications Commission (FCC) Rules and with Industry Canada Standards See Radio Frequency Statement on page 13￿22 for information regarding Part 15 of the Federal Communications Commission (FCC) Rules and with Industry Canada Standards RSS-GEN/210/220/310. When a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light located on the instrument cluster.
