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. If enabled through Personalization, the DIC then returns to the last display status before no power condition.
There are 4 switch functions for the DIC.
- Info
- Maintenance
- Menu
- Set/Reset

Average Fuel Economy
Average fuel economy is calculated using the equation: AFE = Distance/Fuel
- 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 ECM sends the average fuel economy GMLAN message to the 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 options menu.
Average Speed
Average speed is calculated using the equation: Average Speed = AVS Distance/AVS Time
- Distance = The accumulated distance travelled since the last reset of this value
- Ignition On = The accumulated ignition on time since the last reset of this value
Oil Life Remaining
The engine control module (ECM) or the powertrain control module (PCM) sends the oil life remaining percentage to the instrument panel cluster (IPC) via GMLAN message. The instrument panel cluster receives a GMLAN message indicating the engine oil life remaining. The driver information center (DIC) displays the current percentage of the GM Oil Life System as determined by the ECM/PCM. When the oil life remaining percentage drops below 5 percent, the DIC displays CHANGE ENGINE OIL SOON. When the engine oil is changed, reset the GM Oil Life System. Refer to GM Oil Life System - Resetting.
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. 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.
- Fuel Used = The accumulated fuel delivered since the last reset of this value
The ECM/PCM sends the fuel range value to the instrument panel cluster (IPC). The instrument panel cluster (IPC) receives a GMLAN message with fuel information. The fuel range value is retained during ignition OFF and can be changed between English and Metric units by accessing the DIC English/Metric menu. The Fuel Range display cannot be reset. LOW is displayed when fuel range is below a predetermined value.
Instantaneous Fuel Economy (IFE)
Instantaneous fuel economy (IFE) is calculated using the equation: IFE = Distance/Fuel Used.
- Distance = The accumulated distance travelled for the last 2 seconds
- Fuel = The accumulated fuel delivered for the last 2 seconds
The instrument panel cluster (IPC) receives a GMLAN message from the ECM/PCM. The distance information is calculated by the IPC using the vehicle speed information from the ECM/PCM. These values are retained during ignition OFF and can be changed between English and Metric units accessing the DIC English/Metric menu. The IFE display cannot be reset.
Elapsed Time
The timer records elapsed time starting from activation. When the driver information center (DIC) displays the timer, pressing the SET/RESET switch for 1.0 seconds on the DIC resets the timer. Pressing the SET/RESET button on the DIC switch for approximately 1.0 seconds starts and stops the timer. The DIC displays the timer in one of the following formats:
The DIC displays the timer in the following format: XX: XX:XX:
The first XX represents hours elapsed, the second XX represents minutes elapsed, and the third XX represents seconds elapsed. The maximum range of the timer is 99 hours, 59 minutes, and 59 seconds. After the maximum range is reached, the timer displays all zeros (00:00:00).
Tire Pressure Monitor
The instrument panel cluster (IPC) receives a GMLAN message from the tire pressure monitoring (TPM) system for front and rear tire pressure data. The driver information center (DIC) will display the pressure for each of the front and rear tires. When a tire with low air pressure is present, the DIC displays XX TIRE PRESSURE LOW.
Park Assist Menu
The park assist menu is displayed in the DIC. The DIC displays the current state of the park assist until the IPC receives a message indicating otherwise. The DIC displays (- - -) when communication with park assist is lost.
English/Metric Button
The English/Metric button is used to toggle between English and Metric unit systems and can be accessed through the DIC MAINTENANCE switch function.
Trip A/B
The trip odometer A or B can be accessed through the DIC INFO switch function.
Language
The DIC is capable of displaying in three languages
- English
- French
- Spanish
A simultaneous press of the INFO and MENU switches for about 1 second provides a shortcut to change the language without understanding the currently displayed language.
Compass
The DIC displays the compass information on the right most 2 characters of the first DIC line when the compass is an option on the vehicle. When corresponding to the true north radial degrees, the compass displays the following directions
Outside Air Temperature
The DIC displays the outside air temperature based on GMLAN message from the HVAC controller. The IPC receives the outside air temperature information for display in the DIC. The outside air temperature can be displayed in English or Metric systems and the English/Metric menu can be accessed via the DIC maintenance switch. The DIC displays (- - -) when an invalid outside air temperature is received.
