Driver Information Center (DIC)

Driver Information Center (DIC) Description and Operation

The Driver Information Center display is in the instrument cluster. The Driver Information Center displays information about the vehicle. It also displays warning messages if a system problem is detected. For more information on Indicators and Warning messages, refer to Indicator/Warning Message Description and Operation Indicator/Warning Message.

There are 3 switch functions for the driver information center:

* CONFIG: Press to select either the Simple or Enhanced instrument cluster configuration display.
* BACK: Press to return to the previous screen, exit a screen, or return to the main menu. Press BACK to minimize the DIC menu display.
* SELECT: Press the center of the knob to select the highlighted item. Turn the knob to scroll through the menu items.

Menu

Turn the SELECT knob to scroll through the possible menus. Press the center of the SELECT knob when a menu is highlighted to enter that menu. The possible Driver Information Center menu's are:

* Trip A
* Trip B
* Oil Life
* Tire Pressure
* Vehicle Messages
* Units
* Tutorial Mode

Trip A and Trip B

The trip displays show fuel used, average fuel economy, and distance traveled since the last trip reset.

Reset the trip data by pressing and holding the SELECT button when either Trip A or Trip B is displayed.

Oil Life

This displays the percentage of remaining oil life. The lower the percentage, the closer the vehicle is to needing an oil change.

When the oil life is depleted, the CHANGE ENGINE OIL SOON message displays. Change the oil as soon as possible.

The oil life must be reset after each oil change. Avoid accidental resetting of the Engine Oil Life System. It cannot be reset accurately until the next oil change. To reset the Engine Oil Life System, refer to GM Oil Life System Resetting Testing and Inspection. The system is reset when 100% displays.

Outside Air Temperature

The outside air temperature can be accessed through the driver information center Trip/Fuel switch function. The driver information center shows the outside air temperature as a damped value. The time and rate of the temperature update is based on an algorithm in the instrument cluster. Factors such as last temperature reading, current temperature reading, length of time the vehicle was off, current vehicle speed, and the distance driven effect when the displayed temperature is updated. To get the vehicle to display the most accurate temperature faster, drive the vehicle. Constant moving traffic will update the display to the correct temperature more quickly than stop and go traffic.

Tire Pressure

The display will show a vehicle with the approximate pressures of all four tires. Tire pressure is displayed in either kilopascal (kPa) or in pounds per square inch (psi).

If a low or high tire pressure is detected, a message is displayed advising to check the tire pressure in the specified tire.

Vehicle Messages

Turn the SELECT knob to scroll through any active warning messages. Press SELECT to review the messages.

Units

Turn the SELECT knob to change the unit display to METRIC or US when the display is active. Press SELECT to confirm the setting. This will change the displays on the cluster and DIC to either metric or English (US) measurements.

Tutorial Mode

Select this menu item to view a screen that explains some of the unique features of the cluster.

Language

The driver information center is capable of displaying in different languages, corresponding to the radio language settings. The instrument cluster receives a GMLAN message with language information from the radio. This message is only sent one time, after a new language is selected. To set the language, see the owners manual.
