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

Information Mode

INFO/ (Information): Press this button to scroll through the vehicle information mode displays in the following order:

    • TRIP A
    • TRIP B
    • FUEL RANGE (Fuel Range Until Empty)
    • ECON (Average Fuel Economy)
    • AV SPEED (Average Vehicle Speed)
    • OIL LIFE (Engine Oil Life System)
TRIP A or TRIP B: Press the information 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 (mi) or kilometers (km). 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 information button until FUEL RANGE is displayed. This shows the remaining distance you can drive without refueling. It is based on fuel economy and the fuel remaining in the tank. When the fuel level is low, FUEL RANGE LOW displays. 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 (Economy): Press the information button until ECON is displayed. Average fuel economy is how many miles per gallon (mpg) or liters per 100 kilometers (L/100 km) 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 (Average) SPEED: Press the information button until AV SPEED is displayed. This shows the vehicle's average speed in miles per hour (mph) or kilometers per hour (km/h). Press and hold the enter button while AV SPEED is displayed to reset the average vehicle speed.

OIL LIFE: Press the information button until OIL LIFE is displayed. The engine oil life system shows an estimate of the oil's remaining useful life. It shows 100% when the system is reset after an oil change. It will alert you to change the oil on a schedule consistent with your driving conditions. Always reset the engine oil life system after an oil change. See Engine Oil Life System . In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Scheduled Maintenance and Engine Oil .

Personalization

If the vehicle is moving faster than 2 mph (3 km/h), the personalization menu options are not available, except for the UNITS option. All of the personalization options may not be available on your vehicle. Only the options available display on the DIC.
