2011 Buick Lucern Owner's Manual - Page 198

Here are some things that some owners ask about. None of these show a problem with the fuel gauge: . At the service station, the gas pump shuts off before the gauge reads full. It takes more (or less) fuel to fill up than the gauge indicated. For example, the gauge may have indicated half full, but it took more (or less) than half the tank's capacity to fill it. The gauge moves up a little while turning a corner, speeding up or making a hard stop. The gauge does not go back to empty when the ignition is turned off. . The DIC displays trip, fuel, and vehicle system information, and warning messages if a system problem is detected. The bottom line of the DIC shows the shift lever position indicator. See Automatic Transmission Operation on page 3 ‑ 24 for more information. If your vehicle's DIC has these features, the compass direction and the outside air temperature may also display on the DIC when viewing the trip and fuel information. The compass direction appears on the top right corner of the DIC display. The outside air temperature automatically appears in the bottom right corner of the DIC display. If there is a problem with the system that controls the temperature display, the numbers will be replaced with dashes. If this occurs, have the vehicle serviced by your dealer. The DIC also allows some features to be customized. See DIC Vehicle Customization on page 4 ‑ 58 for more information. . . Driver Information Center (DIC) Your vehicle has a Driver Information Center (DIC). All messages will appear in the DIC display located below the speedometer in the instrument panel cluster. The DIC buttons are located on the instrument panel, to the left of the instrument panel cluster. The DIC comes on when the ignition is on. After a short delay, the DIC will display the information that was last displayed before the engine was turned off. DIC Operation and Displays The DIC has different displays which can be accessed by pressing the DIC buttons located on the instrument panel, to the left of the instrument panel cluster. 4-42
