2006 GMC Sierra 1500 Pickup Owner's Manual - Page 233

Always reset the engine oil life system after an oil change. To reset the engine oil life system, see Engine Oil Life System (Gasoline Engine) on page 5-23. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Engine Oil (Gasoline Engine) on page 5-20 and Scheduled Maintenance (Gasoline Engine) on page 6-4. DIC Warnings and Messages Warning messages are displayed on the Driver Information Center (DIC) to notify the driver that the status of the vehicle has changed and that some action may be needed by the driver to correct the condition. If there is more than one message that needs to be displayed, they will appear one after another. Some messages may not require immediate action, but you should press any of the four DIC buttons on the steering wheel to acknowledge that you received the messages and to clear them from the display. If your vehicle does not have DIC buttons on the steering wheel, press the trip odometer reset stem, located on the instrument panel cluster, to acknowledge messages and clear them from the display. Some messages cannot be cleared from the display because they are more urgent. These messages require action before they can be removed from the DIC display. You should take any messages that appear on the display seriously and remember that clearing the messages will only make the messages disappear, not correct the problem. The following are the possible messages that can be displayed and some information about them. Customization Button 4 (Customization): Press the customization button to access the VEHICLE SETTINGS menu and customize the settings to your vehicle. See DIC Vehicle Customization on page 3-64 for more information. Select Button r (Select): Press the select button to reset certain DIC functions and set your customization settings. For example, this button will reset the trip odometers and enables you to scroll through and select the language in which the DIC information will appear. 3-55
