- Press the ODO/TRIP switch to change the display to "b-OFF".
- Turn the ignition switch off.

HINT: "b-OFF" indicates that the buzzer is OFF. "b-ON" indicates that the buzzer is ON. The buzzer ON/ OFF setting will be finished (the odometer will appear) if the ODO/TRIP switch is not operated for 10 seconds or more. In this case, perform step 11 to check that the buzzer ON/OFF setting is complete. If it is not complete, start from step 1 again.
NOTICE:
- When either the battery cable or the combination meter connector is disconnected, these buzzers are set on.
- ODO/TRIP meter returns to 0 after starting this procedure, although it is not displayed.
