Fuel Gage
When the indicator nears empty, you still have a
little fuel left, but you should get more soon.
Your fuel gage tells you about how much fuel
you have left when the ignition is on.Here are four things some owners ask about.
All these things are normal and do not indicate
that anything is wrong with the fuel gage.
At the gas station, the gas pump shuts off
before the gage reads full.
It takes a little more (or less) fuel to ll up
than the gage reads. For example, the
gage read half full, but it took more (or less)
than half of the tank’s capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate empty when the
ignition is turned off.
Low Fuel Warning Light
The light next to the fuel gage will come on briey
when you are starting the engine.
This light comes on when the fuel tank is low on
fuel. To turn it off, add fuel to the fuel tank.

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display
located in the instrument panel cluster, below the
tachometer. 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 will display WELCOME
DRIVER (1 or 2) if a personalized key 1 or 2
is used, and then the information that was last
displayed before the engine was turned off.
The driver number also corresponds to the
numbers, 1 or 2, on the back of the remote
keyless entry transmitters.
The DIC displays the odometer, trip odometers,
fuel economy, trip computer, vehicle system
information, and compass display, if equipped.
It also displays warning messages if a system
problem is detected. In addition, the DIC displays
phone numbers that are called using the
OnStar
®system, if equipped. SeeOnStar®
System on page 145.If equipped, the outside air temperature
automatically appears in the bottom right corner of
the DIC display when viewing all of the information
screens, except for the oil life 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.
The DIC also allows some features to be
customized or personalized, if equipped. See
DIC Vehicle Personalization (Uplevel Only)
on page 249for more information.

Trip A and Trip B
Press the information button until A or B displays.
This mode shows the current distance traveled
in either miles or kilometers since the last reset for
each trip odometer. Both trip odometers can be
used at the same time.
The display will show the odometer on the top line
and the trip odometer information, either A or B,
on the bottom line.
Each trip odometer can be reset to zero separately
by pressing the set/reset button while the desired
trip odometer is displayed.
There is also a retroactive trip odometer function
that performs the following for each trip odometer:
If the vehicle’s speed has exceeded 3 mph
(5 km/h) during the current ignition cycle,
this function will set the trip odometer to the
distance driven during the current ignition cycle.
If the vehicle’s speed has not exceeded 3 mph
(5 km/h), this function will set the trip odometer
to the distance driven during the previous
ignition cycle plus the distance driven during
the current ignition cycle.Press and hold the set/reset button for three
seconds, then release the button. The retroactive
trip odometer value will be set into the currently
displayed trip odometer.
Time Elapsed
Press the information button until TIME
ELAPSED :00 displays. This mode is like a
stopwatch, in that you can clock the time it takes
to get from one point to another. Each of the
elds for the hours, minutes, and seconds are
two numeric digits.
Once TIME ELAPSED :00 is displayed, press
the set/reset button to start the timing feature.
Press the set/reset button again to stop it. If you
will be starting and stopping your vehicle, during
a trip for instance, the TIME ELAPSED feature will
automatically start timing where it left off when
you last stopped. To reset it, press and hold the
set/reset button for approximately 1.5 seconds.
The display will return to zero.
