Headlamps on Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver’s door, you will hear a continuous
warning chime. The chime will turn off when the
lamps are turned off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL, so
be sure it is not covered.The DRL system makes the low-beam headlamps turn
on at reduced brightness in daylight when the
following conditions are met:
The ignition is on.
The exterior lamp button for the headlamps is off.
The automatic transmission is not in PARK (P).
When the DRL are on, only the low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker and
other lamps will not be on.
When it is dark enough outside, the low-beam
headlamps will come on. The other lamps that turn on
with the headlamps will also turn on. When it is
bright enough outside, the regular lamps will go off, and
the low-beam headlamps change to the reduced
brightness of DRL.
To turn off all exterior lighting at night when the vehicle
is parked, turn the exterior lamp control to the off
position. The exterior lamps will turn back on
automatically when the transmission is moved out of
PARK (P). SeeExterior Lamps on page 3-14for
more information.
As with any vehicle, the regular headlamp system
should be turned on when needed.

Operation
(
(Off):Turn the left knob to this position to turn the
climate control system off. Outside air still enters the
vehicle and is directed to the oor. The airow direction
and temperature can be adjusted, as indicated below.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
The fan speed is temporarily reduced between the
transition to a new mode. The fan will resume when the
new mode is complete.
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 3-30and
Scheduled Maintenance on page 6-4.
Temperature Control:Turn the center knob clockwise
or counterclockwise to warm or cool the air coming
through the outlets.
Mode Control:Turn the right knob clockwise or
counterclockwise to change the airow direction.
H(Vent):This mode directs outside air to the
instrument panel outlets.
)(Bi-Level):This mode splits the air between the
instrument panel outlets and the oor outlets. Slightly
cooler air is directed to the instrument panel outlets and
warmer air is directed to the oor outlets.
6(Floor):This mode automatically uses outside air
and directs most to the oor outlets. Some air is directed
toward the side window outlets and to the windshield.
If recirculation is selected while in this mode, it stays on
for three minutes to reduce windshield fogging.
h(Recirculation):Press this button to recirculate
cabin air through the vehicle. An indicator light below the
button comes on to show that this mode is activated.
This mode can be used to prevent outside air and odors
from entering the vehicle or to help cool the air inside
the vehicle more quickly. This mode cannot be selected
while in the defog or defrost modes. If you try to
select the recirculation mode, the indicator light ashes
three times and turns off.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced, select
the defrost mode.
3-22

Automatic Operation
AUTO (Automatic Fan):When AUTO is selected on
the fan control, the system automatically adjusts the fan
speed. If the OnStar
®system is activated when this
position is selected, the fan speed will lower.
AUTO (Automatic Mode)
1. Turn the fan control to AUTO.
2. Turn the mode control to AUTO.
3. Adjust the temperature to a comfortable setting
between 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. In cold weather, the system starts at
reduced fan speeds to avoid blowing cold air into
the vehicle until warmer air is available. The system
will start out blowing air to the oor, but may
change modes automatically as the vehicle warms
up to maintain the chosen temperature setting.
The length of time needed to warm the interior
depends on the outside temperature.
4. Wait a few minutes for the system to automatically
regulate. Then adjust the temperature as necessary
to nd your comfort setting.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.After the vehicle is started, the display shows the
interior temperature settings.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
shows readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between the readings.
AUTO (Automatic Air Conditioning):If AUTO is
selected on the fan or mode control, the system
automatically controls the air conditioning compressor.
The A/C compressor runs automatically even at cool
outside temperatures in order to dehumidify the air. The
A/C indicator light is lit when the system is operating
automatically. Press the A/C button on the fan control to
turn off the A/C. To clear windows better in defog or
defrost modes, the A/C compressor runs automatically
in damp cool conditions.
h(Auto Recirculation):If AUTO is selected on
either the fan or mode control, the system automatically
controls the supply of fresh outside air or recirculates
the interior air to cool the car faster. The indicator
light on the recirculation button will light whenever the
system switches to recirculation. You may force outside
air by pressing the outside air button. The next time
AUTO fan or mode is selected, it will reset back
to AUTO operation.

Fuel Range
Press the trip/fuel button until FUEL RANGE displays.
This display shows the approximate number of
remaining miles (mi) or kilometers (km) the vehicle can
be driven without refueling.
The fuel range estimate is based on an average of the
vehicle’s fuel economy over recent driving history
and the amount of fuel remaining in the fuel tank. This
estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, this 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 your vehicle is low on fuel, the FUEL LEVEL LOW
message will be displayed. See “FUEL LEVEL LOW”
underDIC Warnings and Messages on page 3-56
for more information.
Average Economy
Press the trip/fuel button until AVG ECONOMY displays.
This display 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

item was reset. To reset AVG ECONOMY, press and
hold the set/reset button. The display will return to zero.
Instantaneous Economy
Press the trip/fuel button until INST ECONOMY displays.
This display shows the current fuel economy at a
particular moment and will change frequently as driving
conditions change. This display shows the instantaneous
fuel economy in miles per gallon (mpg) or liters per
100 kilometers (L/100 km). Unlike average economy, this
screen cannot be reset.
Average Speed
Press the trip/fuel button until AVERAGE SPEED
displays. This display 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 speeds recorded since the last reset of
this value. To reset the value, press and hold the
set/reset button. The display will return to zero.
