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.

Information Button Items
Q4R
(Information):Press this button to scroll
through the following items:
Odometer
Press the information button until the odometer
displays. This mode shows the distance the
vehicle has been driven in either miles or
kilometers.
224

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.
225

Average Speed
Press the information button until AVERAGE
SPEED displays. This mode shows the average
speed of the vehicle in miles per hour (mph)
or kilometers per hour (km/h). This average is
calculated based on the various vehicle speed
recorded since the last reset of this value. To reset
the value, press the information button to display
AVERAGE SPEED, then press and hold the
set/reset button. The display will return to zero.
Fuel Range
Press the information button until FUEL RANGE
displays. This mode shows the approximate
number of remaining miles or kilometers the
vehicle can be driven without refueling.
Fuel range is based on several factors, including
distance travelled, fuel used, fuel capacity,
etc. This estimate will change if driving conditions
change. For example, if driving in traffic and
making frequent stops, this mode may read
one number, but if the vehicle is driven on a
freeway, the number may change even though
the same amount of fuel is in the fuel tank.This is because different driving conditions
produce different fuel economies. Generally,
freeway driving produces better fuel economy
than city driving. Fuel range cannot be reset.
If your vehicle is low on fuel, FUEL RANGE LOW
will display followed by the LOW FUEL message.
See “LOW FUEL” underDIC Warnings and
Messages on page 230for more information.
Average Fuel Economy
Press the information button until AVG ECONOMY
displays. This mode shows the approximate
average miles per gallon (mpg) or liters per
100 kilometers (L/100 km). This number is
calculated based on the number of mpg (L/100 km)
recorded since the last time this menu item was
reset. To reset AVG ECONOMY, press and
hold the set/reset button. The display will return
to zero.
Battery
Press the information button until BATTERY
displays. This mode shows the current battery
voltage.
226

Your vehicle’s charging system regulates voltage
based on the state of the battery. The battery
voltage may uctuate when viewing this
information on the DIC. This is normal.
If there is a problem with the battery charging
system, a DIC message will display. See
DIC Warnings and Messages on page 230for
more information.
Oil Life
Press the information button until OIL LIFE
displays. This mode shows an estimate of the oil’s
remaining useful life. If you see OIL LIFE 99%
on the display, that means 99% of the current oil
life remains. The engine oil life system will
alert you to change your oil on a schedule
consistent with your driving conditions.
When the remaining oil life is low, the CHANGE
OIL SOON message will appear on the display.
You should change your oil as soon as possible.
SeeEngine Oil on page 411. In addition to the
engine oil life system monitoring the oil life,
additional maintenance is recommended in the
Maintenance Schedule in this manual. See
Scheduled Maintenance on page 509for more
information.Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself.
Also, be careful not to reset the OIL LIFE
accidentally at any time other than when the oil
has just been changed. It cannot be reset
accurately until the next oil change. To reset
the engine oil life system, seeEngine Oil
Life System on page 414. The display will show
100% when the system is reset.Menu Button Items

Compass Calibration
Under certain circumstances, such as during
a long distance cross-country trip, it will be
necessary to compensate for compass variance
and reset the zone through the DIC.
Compass variance is the difference between the
earth’s magnetic north and true geographic
north. If not adjusted to account for compass
variance, the compass in the vehicle could give
false readings.
In order to do this, the compass must be set or
calibrated to the variance zone in which the vehicle
is traveling.
To adjust for compass variance, use the following
procedure:
1. Press the menu button until COMPASS ZONE
displays.2. Find the vehicle’s current location and
variance zone number on the map.
3. Press the set/reset button to scroll through
and select the appropriate variance zone.
229

4. Press the menu button to advance to the
COMPASS CALIBRATION screen.
5. To start the compass calibration, press and
hold the set/reset button until CALIBRATION
BEGUN DRIVE UNTIL DONE appears in
the DIC display.
6. Drive the vehicle slowly in a circle two times
to activate the compass.
When the calibration is complete, the DIC will
display CALIBRATION FINISHED.
7. If the message CAL appears in the DIC, you
must manually put the compass into the
calibration mode again. Repeat
Steps 1 through 6.DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed
and that some action may be needed by the driver
to correct the condition. Multiple messages may
appear one after another.
Some messages may not require immediate
action, but you can press any of the DIC buttons
to acknowledge that you received the message
and clear it from the DIC display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These
messages require action before they can be
cleared.
If there are any active warning messages when the
vehicle is turned off, two chimes sound and the DIC
goes into a reminder mode. The reminder mode
displays any active message. If there are multiple
messages, the DIC displays each message for ve
seconds. After each active message is displayed
once, the reminder mode turns off.
You should take any messages that appear on
the display seriously and remember that clearing
the messages will only make the messages
disappear, not correct the problem.
