GM Service Manual Online

The DIC comes on when the ignition is on. After a short delay the DIC will display the current driver (1 or 2) and the information that was last displayed before the engine was turned off.

If a problem is detected, a warning message will appear on the display. Pressing any of the four buttons will acknowledge (clear) most current warnings or service messages. Some warnings that cannot be acknowledged (cleared) are: ENGINE OVERHEATED, OIL PRESSURE LOW, REDUCED ENGINE POWER, TRANS HOT IDLE ENGINE, STABILITY SYS ACTIVE, TRACTION SYS LIMITED and TRACTION ACTIVE. These warnings must be dealt with immediately and therefore cannot be cleared until the problem has been corrected.

The DIC has different modes which can be accessed by pressing the four buttons on the DIC. These buttons are trip information, fuel information, personalization and select. The button functions are detailed in the following.

Press the fuel information button until RANGE appears to display the remaining distance you can drive without refueling. It's based on fuel economy and the fuel remaining in the tank. The display will show LOW if the fuel level is low.

The fuel economy data used to determine fuel range is an average of recent driving conditions. As your driving conditions change, this data is gradually updated. Fuel range cannot be reset.

Average Fuel Economy

Press the fuel information button until AVG ECON appears in the display. Average fuel economy is how many miles per gallon your vehicle is getting based on current and past driving conditions.

Instant Fuel Economy

Press the fuel information button until INST ECON appears in the display. Instant fuel economy is how many miles per gallon your vehicle is getting at the particular moment in time. The instant fuel economy cannot be reset.

GM Oil Life System

It will show 100% when the system is reset after an oil change. It will alert you to change your oil on a schedule consistent with your driving conditions.

Always reset the engine oil life after an oil change. To reset the Oil Life System use the fuel button to reach the ENGINE OIL LIFE screen and then press and hold the select button for five seconds while ENGINE OIL LIFE is displayed.
