Compass/Temperature Mode

This mode displays an 8 point compass heading on the left hand side of the DIC. The compass will display the current vehicle direction relative to one of 8 compass headings using N,NE,E,SE,S,SW,W, and NW for the readout. The ambient temperature also displays on the DIC. If the ambient temperature is below 3°C (37°F), the temperature reading will toggle every 8 seconds between displaying the outside temperature and the word ICE for two minutes. If the temperature is less than minus 40°F for more than 2 seconds, OC will display. If the temperature is above 140°F for more than 2 seconds, SC will be displayed. For compass calibration and compass magnetic variation adjustment refer to Electronic Compass Calibration .

Personalization

For personalization features refer to Personalization Description and Operation in Personalization.

Average Fuel Economy (AFE)

AFE is calculated as the ratio between the following values:

    • AFE=Distance/Fuel
    • Distance=The accumulated distance since the last AFE reset
    • Fuel=The accumulated fuel consumption since the last AFE reset

You can reset the AFE mode by depressing and holding the Set button for more than 3 seconds. The value of this mode is retained during ignition OFF.

Instantaneous Fuel Economy (IFE)

Instantaneous fuel economy is calculated as the ratio between the following values:

    • IFE=Distance/Fuel
    • Distance=The accumulated distance since last update
    • Fuel=The accumulated fuel delivered since last update

You cannot reset the IFE mode. The value of this mode is retained during ignition OFF.

Trip Range

Trip Range is calculated between the following values:

    • Trip Range=AFE x Fuel Remaining
    • Fuel Remaining=Fuel sender value of available fuel

You cannot reset the Trip Range mode. The value of this mode is retained during ignition OFF.

Fuel Used

The DIC calculates and displays the total amount of fuel used since the last reset operation.

You can reset the Fuel Used mode by depressing and holding the Set button for more than 3 seconds. The value of this mode is retained during ignition OFF.

Average Speed

Average speed is calculated as the ratio between the following values:

    • Average Speed=Distance/Ignition On
    • Distance=Accumulated distance since last reset
    • Ignition On=Accumulated ignition on time since last reset

Ignition on time is measured from the time that the ignition is turned ON to the time when the ignition is turned OFF.

You can reset the Average Speed mode by depressing and holding the Set button for more than 3 seconds. The value of this mode is retained during ignition OFF.

Oil Life Left

Oil life left % is based on the information the DIC receives from a class 2 message from the PCM. The DIC displays the current % of the GM Oil Life System. When the oil needs changing the change engine oil indicator in the message center turns on. When the engine oil is changed the changed engine oil indicator needs to be cleared out of the message center and the oil life left needs to be reset, refer to GM Oil Life System Resetting . While in this mode press and hold the Set button until 100% is displayed.

English/Metric Display

While in this mode pressing the Set button changes the units in the DIC and HUD from english to metric and vice versa.
