DIC Warnings and Messages Messages are displayed on the 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. Multiple messages may appear one after another. Some messages may not require immediate action, but you can press any of the DIC buttons on the instrument panel or the trip odometer reset stem on the instrument panel cluster to acknowledge that you received the messages and to clear them from the display. Some messages cannot be cleared from the DIC display because they are more urgent. These messages require action before they can be cleared. 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. If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX Diesel manual for more information. BATTERY LOW START VEHICLE When the vehicle's battery is severely discharged, this message will display and four chimes may sound. Start the vehicle immediately. If the vehicle is not started and the battery continues to discharge, the climate controls, heated seats, and audio systems will shut off and the vehicle may require a jump start. These systems will function again after the vehicle is started. CHANGE ENGINE OIL SOON This message displays when the engine oil needs to be changed. When you change the engine oil, be sure to reset the CHANGE ENGINE OIL SOON message. See Engine Oil Life System on page 6‑20 for information on how to reset the message. See Engine Oil on page 6‑17 and Scheduled Maintenance on page 7‑3 for more information. 4-66
