Driver/Vehicle Information Display: Description and Operation
Driver Information Center (DIC) Description and Operation
The driver information center (DIC) displays the DIC WOW for 5 seconds when it first powers up and the DIC displays the information that was last displayed before the engine was turned OFF. The DIC display can be accessed by pressing the trip reset switch. To scroll through the available functions, press and release the trip reset switch.

Average Fuel Economy
Average fuel economy is calculated using the equation: AFE = Distance/Fuel. Press and release the trip reset switch until RANGE and AVG FUEL displays.
* Distance = The accumulated distance travelled since the last reset of this value
* Fuel = The accumulated fuel consumption since the last reset of this value
The engine control module (ECM) sends the average fuel economy serial data message to the instrument panel cluster (IPC). The value of this mode is retained during ignition OFF and can be changed between English units and metric units by selecting from the DIC trip reset switch.
Fuel Range
This message indicates the estimated distance that the vehicle can travel under the current fuel economy and fuel level conditions since the last battery connection to the IPC. Press and release the trip reset switch until RANGE and AVG FUEL displays. Fuel Range is calculated using the equation: Fuel Range = Range Distance/Range Fuel Used.
* Range Distance = The accumulated distance travelled since the last reset of this value.
* Range Fuel Used = The accumulated fuel delivered since the last reset of this value
The ECM sends the fuel range value to the IPC. IPC receives a serial data message with the fuel information. The fuel range value is retained during ignition OFF and can be changed between English and Metric units by accessing the DIC trip reset switch. The Fuel Range display cannot be reset. LOW is displayed when fuel range is below a predetermined value.
Fuel Used
This message indicates the amount of fuel used since last reset. Press and release the trip reset switch until RANGE and INST FUEL displays. Fuel Used is calculated using the equation: Fuel Used = Fuel Sum.
* Fuel Used = The accumulated fuel used since the last reset of this value.
* Fuel Sum = The accumulated fuel sum since the last reset of this value
The ECM sends the fuel used value to the IPC. The IPC receives a serial data message with the fuel information. The fuel used value is retained as long as battery power is available to the DIC. The fuel used value can be changed between English and Metric units by accessing the DIC trip reset switch.
Engine Oil Life Index
The Engine Oil Life Index displays the estimated percentage of oil life remaining. The engine control module (ECM) sends the oil life remaining percentage to the instrument panel cluster (IPC) via the serial data circuit. The driver information center (DIC) displays the current percentage of the GM Oil Life System as determined by the ECM. When the engine oil life remaining percentage drops below 5 percent, the DIC displays CHANGE ENGINE OIL SOON message. When the engine oil is changed, reset the GM Oil Life System. Refer to GM Oil Life System Resetting (Service and Repair) . Press and hold the reset switch until the oil life remaining displays in the DIC.
Hybrid Economy Indicator Menu
The DIC hybrid economy indicator menu is used to enable or disable the hybrid economy indicator. Press and hold the reset switch until the hybrid economy indicator menu displays in the DIC. The DIC displays SET ECO HOLD STEM and provides a choice of ON/OFF.
Tire Programming Menu
The instrument panel cluster (IPC) receives serial data messages from the tire pressure monitoring (TPM) system for the front and rear tire pressure. The driver information center (DIC) displays the pressure for each of the front and rear tires. Tire pressure values are not reset through the DIC.
The tire programming menu is needed to initiate programming of the tire pressure monitor sensors. The DIC only displays the tire programming menu only if the transmission range is in PARK. Press and hold the trip reset switch until the tire programming menu displays.
Compass
The driver information center (DIC) displays the compass based on serial data message from the BCM. The compass module communicates with the body control module (BCM) through a bi-directional data circuit. The instrument panel cluster (IPC) receives compass information from the BCM via the serial data circuit. The compass is displayed in the DIC with other vehicle information and is displayed at the bottom line of the DIC. The compass display is "- -" (dashes) when a malfunction is present with the compass module or a compass serial data communication fault exists. The compass displays 'CAL' or 'C' when the compass needs to be calibrated. Cycle the ignition before performing the compass magnetic variation zone adjustment procedure. The trip/reset switch is used to change the compass zone or calibrate the compass.
Check that the compass module is properly installed in the vehicle since this may cause the compass to malfunction. The embossed arrow on the top of the compass module should be parallel to the centerline of the vehicle.
Your compass may be located in the inside rear view mirror (ISRVM). If your compass is located in the ISRVM, Refer to Compass Calibration and Magnetic Variance (Driver Information Center (DIC)) (Description and Operation)Compass Calibration and Magnetic Variance (Mirror) (Description and Operation) ,Compass Malfunction (DIC) (Compass Malfunction (DIC))Compass Malfunction (Mirror) (Compass Malfunction (Mirror)) or to Automatic Day-Night Mirror Description and Operation (Automatic Day-Night Mirror Description and Operation) .
Key FOB Programming Menu
The key fob programming menu is used to initiate programming of the key fobs. The key fob programming menu can only be achieved with the vehicle transmission in PARK. Press and release the trip reset switch until HOLD STEM TO RELEARN REMOTE KEY displays. Press and release the trip reset switch until REMOTE KEY LEARNING ACTIVE is displayed. Refer to Transmitter Programming (Programming and Relearning) for more information on key fob programming.
English/Metric Units
The English/Metric Units can be accessed through the DIC trip reset switch. Press and release the trip reset switch until UNITS displays and press the trip reset switch to select ENGLISH (default) or METRIC.
Trip
The trip odometer can be accessed through the DIC trip reset switch. This is the current distance travelled in either miles or kilometers. Press and release the trip reset switch until TRIP displays. To reset to zero, press and hold the reset switch while trip odometer is displayed.
Language
The driver information center (DIC) is capable of displaying in the languages listed below. However, the DIC is capable of storing at least 3 different languages at any one time.
* English
* French
* Spanish
Press and hold the reset switch until LANG displays. Once in this display, press the reset switch to select English, Spanish or French.
Outside Air Temperature
The driver information center (DIC) displays the outside air temperature based on serial data message from the HVAC controller. The outside air temperature can be displayed in English or Metric Units. English or Metric Units can be selected from the DIC. The DIC displays (- - -) when an invalid outside air temperature is received or communication is lost with the HVAC controller.
Odometer
The instrument panel cluster (IPC) displays the odometer in the driver information center (DIC) based on vehicle speed information from the ECM. The ECM sends the vehicle speed data to the IPC via the serial data circuit. The IPC calculates and stores the vehicle odometer. When a new valid vehicle speed information is received from the ECM, the IPC calculates and updates the odometer display in the DIC and stores the new reading in non volatile memory. The DIC displays the vehicle odometer information in either miles or kilometers.
