Tire Pressure Monitoring System (TPMS) U.S. Canada SEL/RESET BUTTON This shows that front left tire is losing pressure. To see the inflation pressures of all four tires, press the SEL/RESET button. The display changes as shown above. Each tire pressure is shown in PSI (U.S. models) or in kPa (Canadian models). 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 instrument panel to come on. If this happens, you will see which tire is losing pressure on the multiinformation display along with a ''CHECK TIRE PRESSURE'' message. When any of the tires have low pressure, the tire pressure monitor shows a ''TIRE PRESS. ERROR SYSTEM FUNC NORMAL'' message. When you continue driving after installing the spare tire, you will also see this message on the multiinformation display. 392 2010 RDX
