Main Menu Table Of Contents Tire Pressure Monitoring System (TPMS) Your vehicle is equipped with a tire pressure monitoring system (TPMS) that turns on every time you start the engine and monitors the pressure in your tires while driving. Each tire has its own pressure sensor. If the air pressure of a tire becomes significantly low, the sensor in that tire immediately sends a signal that causes the low tire pressure/TPMS indicator in the instrumental panel and the appropriate tire position indicator on the tire pressure monitor on the multi-information display (see page 273 ) to come on. Low Tire Pressure/ TPMS Indicator When the low tire pressure/TPMS indicator is on, one or more of your tires is significantly underinflated. The multi-information display also shows a ''CHECK TIRE PRESSURE'' message (see page 274 ). You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the vehicle's tire information placard. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Because tire pressure varies by temperature and other conditions, the low tire pressure/TPMS indicator may come on unexpectedly. 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 306 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 275 ). 272 2008 TL
