If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-31and
Scheduled Maintenance on page 6-4.
?(Recirculation):Press this button to turn the
recirculation mode on or off. When the climate control
system is in recirculation mode an indicator light
will come on. This mode prevents outside air from
entering your vehicle. It can be used to prevent outside
air and odors from entering your vehicle and to help
cool the air inside your vehicle more quickly.
Recirculation mode is not available in defrost or
defog mode.
^(Air Conditioning Off):Press this button to turn
the air conditioning compressor off. Press AUTO
to return to automatic operation. When in AUTO, the air
conditioning compressor will come on automatically,
as needed.
Air conditioning does not operate at temperatures below
about 35°F to 40°F (2°C to 4°C). In temperatures
above 40°F (4°C), the air conditioning cannot be turned
off in defrost and defog, as it helps to remove moisture
from the vehicle. It also helps to keep the windows clear.You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days press the AUTO
button and adjust the temperature to a cool, comfortable
setting. To achieve maximum cool down, do the
following:
1. Select the vent mode.
2. Select recirculation mode.
3. Select the A/C on.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.

Fuel Gage
Your fuel gage tells you
about how much fuel you
have left when the
engine is on.
When the needle approaches the low fuel symbol, a
chime will sound and LOW FUEL will appear on
the Driver Information Center (DIC) display. At this
time, you still have a little fuel left, but you should get
more soon.
Press the RESET button to acknowledge a DIC
message(s). Pressing the RESET button will also turn
off a DIC message but the LOW FUEL message
will come on again in 10 minutes if you have not added
fuel to the vehicle.Here are ve things that 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 the full symbol.
It takes more (or less) fuel to ll up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank’s
capacity to t it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate the tank is empty when
the ignition is turned off.
The gage reading may change slightly within the
rst several minutes after starting the vehicle.
SeeDIC Controls and Displays on page 3-49for more
information.

2(Gages):Press this button to display gage
information like oil pressure and temperature, coolant
temperature, automatic transmission uid temperature, if
equipped, battery voltage, and front/rear tire pressures.
TRIP:Press this button to display your total and
trip distance driven, the elapsed time function, your
average speed, and the engine oil life.
OPTION:Press this button to choose personal options
that are available on your vehicle, depending on the
options your vehicle is equipped with, such as door
locks, easy entry seats, and language.
RESET:Press this button, used along with the other
buttons, to reset system functions, select personal
options, and turn off or acknowledge messages on
the DIC.
FUEL Button
The fuel button displays average fuel economy and
instantaneous fuel economy, calculated for your specic
driving conditions, and range information.Average Fuel Economy:The average fuel economy is
viewed as a long-term approximation of your overall
driving conditions. You should reset the average
fuel economy display every time you refuel. If you press
the RESET button in this mode while you are driving,
the system will reset this display and begin guring fuel
economy from that point in time.
Press the fuel button to display average fuel economy,
such as:
AVERAGE FUEL ECONOMY 20.1 MPG or
AVERAGE FUEL ECONOMY 5.3 L/100 km
Instantaneous Fuel Economy:Instantaneous fuel
economy reects only the fuel economy that the vehicle
has right now and will change frequently as driving
conditions change. Unlike average fuel economy, this
menu item cannot be reset.
Press the fuel button again to display instantaneous fuel
economy, such as:
INSTANT FUEL ECONOMY 20.1 MPG or
INSTANT FUEL ECONOMY 5.3 L/100 km
3-50

Fuel Range:The range calculates the remaining
distance you can drive without refueling. It is based on
fuel economy and the fuel remaining in the tank.
Press the fuel button again to display the range,
such as:
RANGE 30 MI or
RANGE 48 km
If the LOW FUEL warning is displayed or if RANGE
is less than 40 miles (64 km), the display will read
RANGE LOW.
The fuel economy data used to determine fuel range is
an average of recent driving conditions. As your
driving conditions change, this data is gradually updated
automatically.
If the vehicle has been idling for a long time, the range
displayed on the DIC could be abnormally low. The
vehicle must be driven 5–10 miles (8–16 km) to get an
accurate reading.
GAGES Button
The gages button displays oil pressure, oil temperature,
coolant temperature, transmission uid temperature
for automatic transmission vehicles only, battery voltage,
and tire pressure information.
Oil Pressure:This display shows the oil pressure.
Press the gages button to display the oil pressure,
such as:
OIL PRESSURE 40 PSI or
OIL PRESSURE 276 kPa
Oil Temperature:This display shows the oil
temperature.
Press the gages button again to display the oil
temperature, such as:
OIL TEMPERATURE 234°F or
OIL TEMPERATURE 112°C
If the oil temperature is low, the display will show OIL
TEMPERATURE LOW. If the oil temperature is high, the
display will show OIL TEMPERATURE HIGH.
3-51

Average Speed:Press the TRIP button until the
average speed is displayed, such as:
AVERAGE SPEED 62 MPH or
AVERAGE SPEED 100 km/h
Press and hold the RESET button to reset to 0.0 mph.
Engine Oil Life:Press the TRIP button until the
engine oil life is displayed, such as OIL LIFE
REMAINING 89%.
This is an estimate of the engine oil’s remaining useful
life. It will show 100% when the system is reset after
an oil change. It will alert you to change your oil
on a schedule consistent with your driving conditions.
When the remaining oil life is low, the system will
alert you with the message CHANGE ENGINE OIL.
Remember, you must reset the engine oil life system
yourself after each oil change. It will not reset itself. To
reset the system, press and hold the RESET button
for three seconds. Also, be careful not to reset the
engine oil life system accidentally at any time other than
when the oil has just been changed. It cannot be
reset accurately until the next oil change.

Label. SeeExtended Mobility Tires on page 5-56and
Ination - Tire Pressure on page 5-58.
HOT ENGINE AIR CONDITIONING OFF:This
message displays when the engine coolant becomes
hotter than the normal operating temperature. To avoid
added strain on a hot engine, the air conditioning
compressor is automatically turned off. When the coolant
temperature returns to normal, the A/C operation will
automatically resume. You can continue to drive
your vehicle. If this message continues to appear, have
the system repaired by your GM dealer as soon as
possible to avoid compressor damage.
ICE POSSIBLE:This message displays when the
outside air temperature is cold enough to create icy
