Main Menu Table Of Contents Tire Pressure Monitoring System (TPMS) For example, if you check and fill your tires in a warm area, then drive in extremely cold weather, the tire pressure will be lower than measured and could be underinflated and cause the low tire pressure/ TPMS indicator to come on. Or, if you check and adjust your tire pressure in cooler conditions, and drive into extremely hot conditions, the tire may become overinflated. However, the low tire pressure/ TPMS indicator will not come on if the tires are overinflated. Refer to page 568 for tire inflation guidelines. If there is a problem with the TPMS, this indicator begins to flash. It stops flashing after approximately 1 minute, then stays on. You will also see a ''CHECK TPMS SYSTEM'' message on the multi-information display (see page 529 ). Although your tire pressure is monitored, you must manually check the tire pressures monthly. Each tire, including the spare, should be checked monthly when the vehicle is cold, and set to the recommended inflation pressure as specified on the vehicle placard and in the owner's manual (see page 570 ). Driving U.S. model Tire Pressure Monitor To select the tire pressure monitor, press the INFO button several times with the ignition switch in the ON (II) position or with the power mode ON. You will see the above display on the multi-information display when each tire pressure is normal. CONTINUED 527 2009 TL
