Your instrument panel lights up whenever the ignition is ON, and the parking lights or the headlights are ON. This control, to the right of the speedometer, adjusts the brightness of your instrument panel lights. Turn it to adjust to the desired level for night driving.
This same control operates as the CHANGE button for the trip odometer. Press it to move through accumulated mileage for up to two different trips. Press once for Trip A. Press again for Trip B. Press and hold for more than one second to reset the selected trip odometer.
