Main Menu Table Of Contents Driving With a Flat Tire Michelin PAX SystemTM If equipped Your vehicle is equipped with the Michelin PAX system. Since each Michelin PAX system tire has an inner support ring that allows it to continue running without air, it may be difficult to immediately judge from its appearance if a tire is punctured. Your vehicle is also equipped with a tire pressure monitoring system (TPMS), and this system may be your first detection of a flat tire. The TPMS monitors the air pressure of all four tires whenever the ignition switch is in the ON (II) position. It will immediately sense if a tire starts to lose its pressure, and give you warning with the low tire pressure/ TPMS indicator in the instrument panel and a ''CHECK TIRE PRESSURE'' message on the multiinformation display. If the indicator and the warning message do not come on again after you inflate the tire to its correct air pressure (see page 421 ), it was probably a natural loss of the air pressure and you can continue driving as before. If the indicator and the message come on again, you probably have a flat tire. In this case, you will see a ''PAX SYSTEM WARNING'' message on the multi-information display. 432 2008 RL
