The TPMS (tire pressure monitoring system) has seven indicators: four tire indicators (on the multi-information display), a low tire pressure indicator (LED indicator), a message indicator (LED indicator), and a TPMS indicator (on the multi-information display). When the TPMS control unit detects low pressure in a tire, or a problem in the system, it turns on, or blinks the appropriate indicator(s), as well as the message indicator.

The low tire pressure indicator

If the system detects low tire pressure in any of the four tires, the low tire pressure indicator and the appropriate tire indicator(s) come on, as well as the message indicator.
If the control unit detects a problem in the system during an indication of low tire pressure, it will turn off the tire indicator(s), store the DTC(s), and turn on the TPMS indicator and the low tire pressure indicator after blinking.

The TPMS indicator

If a problem in the system is detected, the TPMS indicator come on, as well as the message indicator, and the low tire pressure indicator comes on after blinking for about 75 seconds.
If low tire pressure and a problem in the system are detected, the TPMS indicator comes on, as well as the message indicator, and the low tire pressure indicator comes on after blinking for about 75 seconds.

If the system is OK, the low tire pressure indicator should come on when you turn the ignition switch to ON (II), and then go off 2 seconds later. If it doesn't, there is a problem with the system.

If a problem is detected in the system, most DTCs will cause the TPMS indicator and the low tire pressure indicator (starts blinking) to come on and stay on until the system returns to normal. If DTC 45, 61, 63, 65, 67, 81, 83, or 85 is set, the TPMS indicator with the message indicator and the low tire pressure indicator will go off only when the ignition switch is turned to LOCK (0).
