Tire pressure monitoring system (USA only) Important safety notes If a tire pressure monitor is installed, the vehicle's wheels have sensors installed that monitor the tire pressures in all four tires. The tire pressure monitor warns you when the pressure drops in one or more of the tires. The tire pressure monitor only functions if the correct wheel electronics units are installed in all wheels. Z Tires and wheels Press the a button. The Tire Pressure Now OK? message appears in the multifunction display. X Press 9 or : to select Yes. X Press the a button.

Accordingly, when the low tire pressure indicator lamp lights up, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance and it is the driver's responsibility to maintain correct tire pressure, even if underinflation has not
