System Description
When the vehicle has reached a speed of 40 km/h (25 MPH) or greater, the BCM receives a signal transmitted from the tire pressure sensors installed in each wheel. If the BCM detects low inflation pressure or a system malfunction, it sends a signal to the combination meter via CAN communication to illuminate the low tire pressure warning lamp.In addition, a warning message will be displayed in the vehicle information display. Refer to the Owner’s Manual for additional information.
The tire pressure monitoring system (TPMS) has Easy fill tire alert function to aid in tire inflation. Refer to WT- 9, "Easy Fill Tire Alert Function".

During the use of easy fill tire alert function.
Easy Fill Tire Alert Function
NOTE: The easy fill tire alert function is recommended to use with the power switch ON.
NOTE: When beginning tire inflation, it takes a few seconds for the Easy fill tire alert to function. If there is no response for approximately 15 seconds or more, cancel the Easy fill tire alert function and move the vehicle approximately 1 m (3.2 ft) backward or forward to try again.
