370 STARTING AND OPERATING The suggested rotation method is shown in the following found on the tire placard located on the driver's-side B-pillar. diagram. The tire pressure will vary with temperature by about 1 psi (6.9 kPa) for every 12°F (6.5°C). This means that 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 a vehicle has not been driven for more than three hours - and in outside ambient temperature. 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. Tire Rotation The TPMS will warn the driver of a low tire pressure if TIRE PRESSURE MONITOR SYSTEM (TPMS) The TPMS will warn the driver of a low tire pressure the tire pressure falls below the low pressure warning based on the cold inflation tire pressure requirements threshold for any reason, including low temperature effects, or natural air pressure loss through the tire.
