Driver Information Center (Dic); Dic Operation And Displays - Buick Lucerne 2011 Owner's Manual

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.

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.
4-42
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.

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.
