Engine Coolant Temperature
Warning Light
This light indicates that
the engine coolant has
overheated or the
radiator cooling fan
is not working.
If the vehicle has been operating under normal driving
conditions, pull off the road, stop the vehicle, and turn off
the engine as soon as possible.
SeeCooling System on page 5-30for more information.
Engine Coolant Temperature Gage
The vehicle has a gage
that shows the engine
coolant temperature.
If the gage pointer moves into the shaded area, the
engine is too hot. That reading means the engine
coolant has overheated. If you have been operating the
vehicle under normal driving conditions, you should
pull off the road, stop the vehicle, and turn off the engine
as soon as possible.
SeeCooling System on page 5-30for more information.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives important
safety and maintenance facts. When the vehicle’s
ignition is turned on, all of the DIC lights illuminate for a
few seconds and an introductory message will appear.
After this, the DIC will begin working.
DIC Controls and Displays
(Base Level DIC)
The Driver Information Center (DIC) control buttons and
the message display screen are located above the radio.
The DIC gives important safety and maintenance facts
concerning the vehicle. The status of many of the
vehicle’s systems along with driver personal
programming mode menus and warning messages about
the vehicle’s systems may display on the DIC screen.
The vehicle’s transaxle position will also appear.
The buttons on the base level are trip odometer,
set/reset, and options.
Trip Odometer
3(Trip Odometer):Press this button to access the
odometer and trip distance modes.
The rst menu on the DIC screen will be the odometer
reading, or cumulative mileage of the vehicle. The
odometer cannot be reset.
Press the trip odometer button to advance to the
next menu.
Trip Distances:This menu shows the distances that
the vehicle has driven between speci c points. The trip
odometer will record the number of miles up to
9,999.9 miles or 9 999.9 km travelled for up to two trips.
When 9,999.9 miles or 9 999.9 km is reached for either
trip, the odometer for that trip will go back to zero.
Press the trip odometer button again to access TRIP A.
Press the trip odometer button again to access TRIP B.
To reset the trip odometer(s) back to zero miles or
kilometers, access the trip to reset and press the set/
reset button.
The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to the
number of miles or kilometers driven since the ignition
was last turned on. This can be used if the trip odometer
was not reset at the beginning of the trip.

DIC Controls and Displays (Uplevel
DIC with Trip Computer)
The Driver Information Center (DIC) control buttons and
the message display screen are located above the
radio. The DIC gives important safety and maintenance
facts concerning the vehicle. The status of many of
the vehicle’s systems along with driver personalization
menus and warning messages about the vehicle’s
systems may display on the DIC screen.
The outside temperature automatically appears on the
bottom right corner of the DIC display screen. If the
outside temperature is below 38°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 GM dealer.
The vehicle’s transaxle position and the direction the
vehicle is traveling will also appear on the DIC screen.The compass is self-calibrating, which eliminates the
need to manually set the compass. However, 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. See “Setting the Compass” later in this section for
more information.
The buttons on the DIC trip computer are gages, trip
odometer, set/reset, options, and fuel.
Gages
2(Gages):Press this button to access the OIL LIFE
REMAINING, TRANSMISSION FLUID TEMPERATURE,
BATTERY, ENGINE HOURS, ENGINE BOOST, and
MAXIMUM Gs modes.
3-60
Fuel
.(Fuel):Press this button to access the Average
Fuel Economy, Instantaneous Fuel Economy, and Fuel
Range modes.
AVG ECONOMY (Average Fuel Economy):This
screen will display 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 the average fuel economy for the vehicle,
follow this procedure:
1. Press the set/reset button to reset to zero.
2. Press the fuel button again to advance to the
next screen.
INST ECONOMY (Instantaneous Fuel
Economy):This screen displays the current fuel
economy at a particular moment and will change
frequently as driving conditions change. Unlike average
fuel economy, this screen cannot be reset.
Press the fuel button again to advance to the next
screen.RANGE:This screen displays the approximate number
of remaining miles or kilometers the vehicle can be
driven without refueling. This estimate is based on the
average fuel economy for the amount of fuel remaining
in the fuel tank and the current driving conditions.
This estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, the display 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.
If the fuel tank contains less than 2 gallons (7.6 L), the
LOW FUEL message will appear on the DIC screen.
Fill the fuel tank as soon as possible to avoid running
out of fuel. See “Low Fuel” underDIC Warnings
and Messages on page 3-72.

DIC Warnings and Messages
These messages will appear if there is a problem in
one of the vehicle’s systems. They will override
any other mode or screen the Driver Information

until the problem indicated by the warning message
is taken care of. When the problem indicated by
the message is resolved, it can be acknowledged and
the screen can be reset.
Be sure to take any message that appears on the DIC
screen seriously and remember that clearing the
messages that are able to be acknowledged, will only
make the message disappear, not the problem.
A/C OFF FOR ENGINE PROTECTION
This warning message comes on when the engine
coolant becomes hotter than the normal operating

This message appears when the system detects that
the battery voltage is dropping beyond a reasonable
level. The battery saver system will start reducing certain
features of the vehicle which you may not be able to
notice. At the point that the features are disabled,
this message is displayed. It means that the vehicle is
trying to save the charge in the battery. Turn off all
unnecessary accessories to allow the battery to

CHECK GAS CAP
This warning message comes on when the gas cap is
not on, or is not fully tightened. Check the gas cap
to ensure it is on and properly tightened. The diagnostic
system can determine if the fuel cap has been left off
or improperly installed. A loose or missing fuel cap
will allow fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should

CHECK TIRE PRESSURE
This symbol comes
on with the CHECK
TIRE PRESSURE
warning message.
If the vehicle has ABS brakes, this warning message
will appear when the air pressure in one of the tires
is too low or too high. Check the vehicle’s tire pressure
as soon as possible, and ll or de ate the affected
tire to the appropriate level. The correct tire in ation
pressure should be set to those shown on the
tire-loading information label on the vehicle. See
Loading Your Vehicle on page 4-33for more information.
The CHECK TIRE PRESSURE screen is reset when
it is acknowledged. However, the TIRE INFLATION
MONITOR SYSTEM screen, located under the option
menu in the DIC, must also be reset. See “Tire In ation
Monitor System” in the options section underDIC
