2008 PONTIAC G6 Owners Manual

Maximum Air Conditioning
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the
Cvent mode.
2. Select the highest fan speed.
3. Select
#air conditioning.
4. Select the
?recirculation mode.
5. Select the coolest temperature.
Using these settings together for long periods of time can
cause the air inside of the vehicle to become too dry. To
prevent this from happening, after the air in the vehicle
has cooled, turn the recirculation mode off.
If your vehicle has the remote start feature, it will turn
on using the last settings selected on the climate control
before the vehicle was turned off.
The fan and air delivery knobs can be used during
remote start. The buttons will not work until the ignition
is turned on by the key.
The climate control system changes back to manual
operation when the vehicle key is turned to ON/RUN.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to choose from to
clear fog or frost from your windshield. Use the
defog mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more quickly.
Turn the right knob to select the defog or defrost mode.
-(Defog):Turn the knob to this setting to direct
the air between the windshield and the oor outlets with
a small amount directed to the side windows. This
mode automatically turns off recirculation. The air
conditioning compressor runs unless the outside
temperature is at or below freezing. The air conditioning
compressor operates although the indicator light is
not on. The air conditioning indicator light turns off when
defog is selected. If the air conditioning button is
pressed while in defog mode, the indicator light turns
on. If the button is pressed again, the light turns off. The
recirculation mode cannot be selected while in the
defog mode. Do not drive the vehicle until all the
windows are clear.

1(Defrost):Turn the knob to this setting to direct
most of the air to the windshield with some air directed
to the oor vents. In this mode, the system automatically
forces outside air into the vehicle. The air conditioning
compressor runs unless the outside temperature is at or
below freezing. The air conditioning compressor
operates although the indicator light is not on. The air
conditioning indicator light turns off when defrost is
selected. If the air conditioning button is pressed while
in defrost mode, the indicator light turns on. If the
button is pressed again, the light turns off. Recirculation
cannot be selected while in the defrost mode.
To help clear the windshield quickly, do the following:
1. Select the defrost mode.
2. Select the highest temperature.
3. Select the highest fan speed.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
defogger on or off. An indicator light comes on to
indicate that the rear window defogger is on. Be sure to
clear as much snow as possible from the rear window.If driving below 50 mph (80 km/h), the rear window
defogger turns off about 15 minutes after the button is
pressed. If turned on again, the defogger only runs
for about seven and one-half minutes before turning off.
The defogger can also be turned off by pressing the
button again or by turning off the engine.
If your vehicle’s speed is maintained above 50 mph
(80 km/h), the rear window defogger remains on once
the button is pressed.
If your vehicle has the remote start feature, the rear
defogger automatically turns on if it is cold outside.
When the vehicle transitions out of the remote start
mode, the rear defogger turns off. SeeRemote Keyless
Entry (RKE) System Operation on page 2-4.
Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.

Automatic Climate Control System
If your vehicle has this system, the heating, cooling, and
ventilation can be automatically controlled in your vehicle.
Automatic Operation
AUTO (Automatic):Select AUTO on both the fan
speed control and the air delivery mode control knobs to
activate the automatic system. Automatic operation
controls the inside temperature and air delivery.
Use the steps below to place the climate control system
in automatic mode:
1. Turn the fan knob and the mode knob to AUTO.
The display shows the current set temperature.
When auto is selected, the air conditioning operation
and air inlet is automatically controlled. The airconditioning compressor runs when the outside
temperature is over about 40°F (4°C). The air inlet
is normally set to outside air. If it is hot outside,
the air inlet can automatically switch to recirculate
inside air to help quickly cool down your vehicle.
2. Set the temperature.
To nd your comfort setting, start with an initial
temperature setting and allow about 20 minutes for
the system to regulate. Press the up or down
arrow temperature buttons to adjust the temperature
setting as necessary. If you choose the temperature
setting of 60°F (15°C) the system remains at the
maximum cooling setting. If you choose the
temperature setting of 90°F (32°C) the system
remains at the maximum heat setting. Choosing
either maximum setting will not cause the vehicle to
heat or cool faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield. This
sensor regulates air temperature based on sun
load, and also turns on your headlamps.
Also be careful not to cover the sensor grille on the
lower right side of the climate control faceplate.
This senses the inside vehicle temperature needed
for proper regulation.
3-23

To avoid blowing cold air at start-up in cold weather,
the system delays turning on the fan until warm air is
available. The length of delay depends on the engine
coolant temperature. Turning the fan knob overrides
this delay and change the fan to a selected speed.
If your vehicle has the remote start feature, the climate
control display initially shows “AS” in place of the
temperature to indicate the remote start has been
activated. The remote start system turns on using the
last temperature selected before the vehicle was
last turned off.
For best performance, turn the fan and mode knobs to
the AUTO position. The fan speed and air delivery
modes will change to achieve the best comfort.
If the outside air temperature is below 45°F and the air
delivery mode knob is set to AUTO, the automatic
climate control system starts in the defrost mode to clear
the window.
The automatic climate control changes back to manual
operation by turning the vehicle on with the key.
Manual Operation
The air delivery mode or fan speed can be manually
adjusted.
9(Off):Select this position on the fan knob to turn off
the entire climate control system. Outside air still
enters the vehicle, and is directed to the oor.This direction can be changed by changing the mode
position. The temperature can also be adjusted
using either the up or down arrow temperature buttons.
9(Fan):Turn the knob with the fan symbol to
manually adjust the fan speed.
H(Vent):Turn the knob to this position to direct air
to the instrument panel outlets.
)(Bi-Level):Turn the knob to this position to direct
half of the air to the instrument panel outlets, and
the remaining air to the oor outlets.
6(Floor):Turn the knob to this position to direct most
of the air to the oor outlets with some air directed to
the side window outlets and windshield.
The right knob can also be used to select defog or
defrost modes. See Defogging and Defrosting later in
this section.
:(Outside Air):Press the right side of this button
to turn the outside air mode on. Air from outside
the vehicle circulates throughout your vehicle. An
indicator light comes on to show that it is activated. The
outside air mode can be used with all modes, but it
cannot be used with the recirculation mode. Press this
button to cancel the recirculation mode.
3-24

?(Recirculation):Press the left side of the button
to turn the recirculation mode on. The air inside the
vehicle is recirculated through the climate control system
and throughout the vehicle, not from outside. This
mode is helpful when you are trying to limit odors from
entering your vehicle and for maximum air conditioning
performance in hot weather. An indicator light above
the button comes on to show that it is activated.
If recirculation is selected while in defrost, defog, or
oor, the light on the button ashes three times
and goes out to let you know this is not allowed. Use
this mode only when it is needed for comfort, since
window fogging occurs if the air conditioning compressor
is not engaged.
Press this button to cancel the auto recirculation
feature. Each time the vehicle is started, the system
reverts to the auto recirculation function.
When the weather is cool or damp, operating the
system in recirculation for extended periods of time can
cause fogging of the vehicle’s windows. To clear the
fog, select either defog or defrost. Make sure the
air conditioning is on.
Temperature Control:Press the up and down arrows
to increase or decrease the temperature inside the
vehicle.#(Air Conditioning):Press this button to turn the air
conditioning compressor on and off. A light above the
button comes on while the air conditioning is on.
When air conditioning is selected or in AUTO mode, the
system runs the air conditioning automatically to cool
and dehumidify the air entering the vehicle.
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for
the vehicle to cool down. Then keep the windows closed
for the air conditioner to work its best.
On cool, but sunny days while using manual operation
of the automatic system, use bi-level to deliver warm
air to the oor and cooler air to the instrument
panel outlets. To warm or cool the air, press the
temperature buttons to the desired setting.
In AUTO mode the system cools and dehumidies the
air inside the vehicle. Also, the system maximizes
its performance by using recirculation as necessary.
Heating:On cold days when using manual operation of
the automatic system, choose oor mode to deliver
air to the oor outlets. To warm or cool the air delivered,
push the temperature buttons to the desired setting.
To use the automatic mode, turn the knob to AUTO and
adjust the temperature by pressing the temperature
buttons.

Defogging and Defrosting
Use either the defog or front defrost to clear fog or frost
from the windshield.
-(Defog):Turn the mode knob to this position to
clear the windows of fog or moisture. This setting
delivers air to the oor and windshield outlets.
0(Defrost):Turn the mode knob to this position to
defrost the windshield. The system automatically
controls the fan speed if AUTO mode is selected. If the
outside temperature is 40°F (4°C) or warmer, the air
conditioning compressor automatically runs to help
dehumidify the air and dry the windshield. The air
conditioning indicator light blinks three times if you try to
turn off the compressor while in this mode.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press this button to turn the rear window
defogger on or off. An indicator light above the
button comes on to indicate that the rear window
defogger is activated.If driving below 50 mph (80 km/h), the rear window
defogger turns off about 15 minutes after the button is
pressed. If turned on again, the defogger will only run for
about seven and one-half minutes before turning off.
If your vehicle’s speed is maintained above 50 mph
(80 km/h), the rear window defogger remains on once
the button is pressed.
If your vehicle has the remote start feature, the rear
defogger automatically turns on if it is cold outside, but
the indicator light does not come on. When the
vehicle transitions out of remote start mode the rear
defogger turns off.
Notice:Do not use a razor blade or sharp object to
clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not be covered by your warranty.
Outlet Adjustment
Rotate the instrument panel outlets and move the
louvers on the outlets to change the direction and
amount of airow in your vehicle.

Operation Tips
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that can
block the ow of air into your vehicle.
Use of non-GM approved hood deectors can
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
When an objectionable odor outside the vehicle is
encountered, use the recirculation mode, with the
temperature knob at a comfortable setting to prevent
the odor from entering the vehicle through the
ventilation system. This can be helpful when driving
through a long tunnel with poor ventilation.
However, extended usage of this mode in cold or
cool weather can cause window fogging.
Warning Lights, Gages, and
Indicators
This section describes the warning lights and gages on
your vehicle.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As the
details show on the next few pages, some warning lights
come on briey when you start the engine just to let you
know they are working. If you are familiar with this
section, you should not be alarmed when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
as you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s
advice. Waiting to do repairs can be costly and even
dangerous. So get to know your vehicle’s warning lights
and gages. They can be a big help.
