Driver Information Center (DIC)
Your vehicle may have a Driver Information
Center (DIC).
All messages will appear in the DIC display
located in the instrument panel cluster, below the
speedometer. The DIC buttons are located on
the center of the instrument panel, below
the center outlets.
The DIC comes on when the ignition is on. After a
short delay, the DIC on the uplevel vehicle will
display the WELCOME DRIVER (1 or 2) if apersonalized key 1 or 2 is used, and then the
information that was last displayed before
the engine was turned off.
The DIC on the base level vehicle displays the
odometer and trip odometers only.
The DIC on the uplevel vehicle displays the
odometer, trip odometers, fuel economy, trip
computer, vehicle system, and compass display
information. It also displays warning messages if a
system problem is detected. In addition, the DIC
on the uplevel vehicle displays phone numbers
that are called using the OnStar
®system, if
equipped. SeeOnStar®System on page 126.
The outside air temperature automatically appears
in the bottom right corner of the uplevel DIC
display when viewing the trip/odometer screens,
fuel screens and some of the gages screens. If the
outside air temperature is at or below 37°F
(3°C), the temperature reading will toggle between
displaying the outside temperature and the
word ICE for two minutes. If there is a problem
with the system that controls the temperature
display, the letters OC (open circuit) or SC (short
circuit) will appear on the display. If this occurs,
have the vehicle serviced by your dealer.

{CAUTION:
If you spill fuel and then something
ignites it, you could be badly burned.
Fuel can spray out on you if you open
the fuel cap too quickly. This spray can
happen if your tank is nearly full, and is
more likely in hot weather. Open the fuel
cap slowly and wait for any hiss noise to
stop. Then unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon as
possible. SeeWashing Your Vehicle on page 442.
When replacing the fuel cap, turn it clockwise until
it clicks. Make sure the cap is fully installed. The
diagnostic system can determine if the fuel cap
has been left off or improperly installed. This would
allow fuel to evaporate into the atmosphere.

warning light, which will be displayed on the
instrument panel cluster if the fuel cap is not
properly installed. SeeCheck Gas Cap Light
on page 199for more information.
If your vehicle has a Driver Information Center
(DIC), the CHECK GAS CAP message will
be displayed if the fuel cap is not properly
installed. SeeDIC Warnings and Messages
