The trip odometer shows how far the vehicle has been driven since the trip odometer was last set to zero.
Press the reset button, located on the instrument panel cluster next to the voltmeter, to toggle between the trip odometer and the regular odometer. Holding the reset button for approximately one second while the trip odometer is displayed will reset it.
To display the odometer reading with the ignition off, press the reset button.
