Tire Pressure Monitoring System

*

The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all four tires. If 

the air pressure of one or more tires is too low, the system warns the driver by indicating the 

tire pressure monitoring system warning light in the instrument cluster and operating a beep 

sound. The system monitors the tire pressures indirectly using the data sent from the ABS 

wheel speed sensors.

To allow the system to operate correctly, the system needs to be initialized with the specified 

tire pressure (value on the tire pressure label). Follow the procedure and perform the 

initialization.

Refer to Tire Pressure Monitoring System Initialization on page 

4-126.

The warning light flashes when the system has a malfunction.

Refer to Warning Lights on page
