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 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. BATTERY NOT CHARGING On some vehicles, if the battery is not charging during operation, this message will appear on the DIC. Driving with this problem could drain your battery. Have the electrical system checked by your GM dealer as soon as possible. See Battery Warning Light on page 3-40 and Voltmeter Gage on page 3-41. Pressing any of the four DIC buttons will acknowledge the message and clear it from the DIC display. If your vehicle does not have the four DIC buttons, pressing the trip odometer reset stem will acknowledge the message and clear it from the DIC display. BUCKLE PASSENGER If your vehicle has the passenger sensing system, this message reminds you to buckle the passenger's seat belt. See Passenger Sensing System on page 1-82. This message will display and a chime will sound when the ignition is on, the driver's seat belt is buckled, the passenger's seat belt is unbuckled with the passenger airbag enabled, and the vehicle is in motion. You should have the passenger buckle their seat belt. 3-56
