The driver information center (DIC) displays the DIC WOW for 5 seconds when it first powers up. If enabled through Customization menu, the DIC then 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 Info switch.

The Vehicle Information switch is used to navigate between vehicle information parameters. Cycle through the following vehicle parameters by successive pressing of the Vehicle Information switch.

The customization switch is used to set personalization features for the vehicle. Many of the parameters in the Trip/Fuel menu and the Vehicle Info menu can be programmed through the customization switch. In addition to the parameters in the Trip/Fuel and Vehicle Info menus, the following features can also be programmed. Refer to the vehicle owner's manual for more customization information.

Press the Set/Reset button in 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 ECM sends the average fuel economy serial data 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 English/Metric 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 instrument panel cluster (IPC). The fuel range value is retained during ignition OFF and can be changed between English and Metric units by accessing the English/Metric 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 the serial data circuit. The instrument panel cluster receives a serial data 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. 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.

The instrument panel cluster (IPC) receives a serial data 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.

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

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

The DIC is capable of displaying in three languages:

A simultaneous press of the vehicle Information and customization switches for about 1 second provides a shortcut to change the language without understanding the currently displayed language. The Language settings may also be assessed through the customization switch.

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
