The driver information center (DIC) displays the DIC WOW for 5 seconds when it first powers up. The DIC returns to the last display status before no power condition.

There are 4 switch functions for the DIC.

The trip/fuel switch is used to navigate between vehicle fuel information parameters. Cycle through the following vehicle parameters by successive pressing of the trip/fuel switch.

Press the Set/Reset button on order to set or acknowledge any of the switch menu options.

Average Fuel Economy

Average fuel economy is calculated using the equation: AFE = Distance/Fuel

The engine control module (ECM) sends the distance and fuel economy message to the instrument panel cluster (IPC) for accumulation. The value of this mode is retained during ignition OFF and can be changed between English units and metric units by selecting from the Vehicle Information menu.

Average Speed

Average speed is calculated using the equation: Average Speed = AVS Distance/AVS Time

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.

The ECM sends the fuel range value to the IPC. The fuel range value is retained during ignition OFF and can be changed between English and Metric units by accessing the Vehicle Information menu. The Fuel Range display cannot be reset. LOW is displayed when fuel range is below a predetermined value.

The engine control module (ECM) sends the engine oil life remaining percentage to the instrument panel cluster (IPC) via a GMLAN serial data message for display. When the ECM detects that the oil life remaining percentage drops below 5 percent, it sends the IPC a GMLAN message to display CHANGE ENGINE OIL SOON. When the engine oil is changed, reset the GM Oil Life System. Refer to GM Oil Life System Resetting.

The instrument panel cluster (IPC) receives a GMLAN message from the tire pressure monitoring (TPM) system for the front and rear tire pressure. 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 Check Tire Pressure.

Press the vehicle information button until PRESS TO RESET TIRE SYSTEM displays. This display allows you to reset the tire pressure system. Once in this display, press the set/reset button to reset the system. The message TIRE PRESSURE SYSTEM RESET will display after the system has been reset.

The park assist menu is displayed in the DIC. The DIC displays the current state of the park assist - ON/OFF. The IPC receives a serial data message indicating the state of the park assist system. The DIC displays (-- -- --) when communication with the park assist system is lost.

The English/Metric button is used to toggle between English and Metric unit system and can be accessed through the Vehicle Information switch function.

The trip odometer A or B can be accessed through the Trip/Fuel information switch.

The DIC is capable of displaying in 3 languages:

A simultaneous press of the Vehicle Information switch and the Customization (Personalization) switch for about 2 second provides a shortcut to change the language without understanding the currently displayed language.

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

The driver information center (DIC) displays the outside air temperature based on GMLAN message from the HVAC controller. The outside air temperature can be displayed in English or Metric systems from the Vehicle Information menu. The DIC displays (-- -- --) when an invalid outside air temperature is received or communication is lost with the HVAC controller.
