The DIC comes on when the ignition is ON. If your vehicle has the uplevel audio system, the time and outside temperature will be shown on the first line of the display and the DIC information will be on the second line of the display.

The DIC has different modes which can be accessed by pressing the DIC buttons. The button functions are detailed in the following.

Information Mode (INFO Button)

Use the INFO button to scroll through the vehicle information mode displays in the following order:

    • TRIP Odometer A
    • TRIP Odometer B
    • FUEL RANGE (Fuel Range Until Empty)
    • ECON (Average Fuel Economy)
    • AV SPEED (Average Vehicle Speed)
    • OIL LIFE (Oil Life Monitor System)
TRIP A or TRIP B: Press the INFO button until TRIP A or TRIP B is displayed. This shows the current distance traveled since the last reset for each trip odometer in either miles or kilometers. Both odometers can be used at the same time. Each trip odometer can be reset to zero separately by pressing and holding the ENTER button for a few seconds while the desired trip odometer is displayed.

FUEL RANGE: Press the INFO button until FUEL RANGE appears, to display the remaining distance you can drive without refueling. It's based on fuel economy and the fuel remaining in the tank. The fuel economy data used to determine fuel range is an average of recent driving conditions. As your driving conditions change, this data is gradually updated. Fuel range cannot be reset.

ECON: Press the INFO button until ECON appears in the display. Average fuel economy is how many miles per gallon or liters per 100 kilometers your vehicle is getting based on current and past driving conditions. Press and hold the ENTER button while ECON is displayed to reset the average fuel economy. Average fuel economy will then be calculated starting from that point. If the average fuel economy is not reset, it will be continually updated each time you drive.

AV SPEED: Press the INFO button until AV SPEED appears in the display. This is the vehicle's average speed in miles per hour or kilometers per hour. Press and hold the ENTER button while AV SPEED is displayed to reset the average vehicle speed.

OIL LIFE: Press the button until OIL LIFE appears in the display. The Oil Life Monitor system shows an estimate of the oil's remaining useful life. It will show 100% when the system is reset after an oil change. It will alert you to change your oil on a schedule consistent with your driving conditions. Always reset the engine oil life after an oil change.
