Here are some things that some owners ask about. None of these show a problem with your fuel gage: Driver Information Center (DIC) Your vehicle may be equipped with a Driver Information Center (DIC). The DIC will display information about how your vehicle is functioning, as well as warning messages if a system problem is detected. This feature also allows two different drivers to store and recall their own personal choice settings. See DIC Controls and Displays on page 3-47 for more information. • At the service station, the gas pump shuts off before the gage reads full. • It takes more (or less) fuel to fill up than the gage indicated. For example, the gage may have indicated half full, but it took more (or less) than half the tank's capacity to fill it. • The gage moves up a little when you turn a corner, speed up or make a hard stop. DIC Controls and Displays When you turn the ignition on, the DIC will display your DRIVER NUMBER. You can have your GM dealer program your name to appear on this display line. See your GM dealer for more information. The system will then perform a status check and display any messages if a problem is detected. If there are no problems detected, the display will return to the mode selected by that driver the last time the ignition was turned off. • The gage doesn't go back to empty when you turn off the ignition. 3-47
