STARTING AND OPERATING 351 Tire Rotation when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on "cold inflation tire pressure". This is defined as the tire pressure after the vehicle has not been driven for at least three hours, or driven less than 1 mile (1.6 km) after a three hour period. The cold tire inflation pressure must not exceed the maximum inflation pressure molded into the tire sidewall. Refer to "Tires - General Information" in "Starting and Operating" for information on how to properly inflate the vehicle's tires. The tire pressure will also increase as the vehicle is driven - this is normal and there should be no adjustment for this increased pressure. 5 TIRE PRESSURE MONITORING SYSTEM (TPMS) The TPMS will warn the driver of a low tire pressure if The Tire Pressure Monitor System (TPMS) will warn the the tire pressure falls below the low-pressure warning driver of a low tire pressure based on the vehicle recomlimit for any reason, including low temperature effects, or mended cold placard pressure. natural pressure loss through the tire. The tire pressure will vary with temperature by about 1 psi (6.9 kPa) for every 12°F (6.5°C). This means that
