Automatic Climate Control System
The heating, cooling, and ventilation for the vehicle can be controlled with
this system. For vehicles with the remote start feature, the climate control
system will turn on with a remote start. SeeRemote Vehicle Start on page 2-6.

control system off. Press any
button to turn the system on again.
While the climate control system is
off the recirculation and rear window
defogger can still be turned on.
Automatic Operation
AUTO (Automatic): When this
button is pressed, the system
automatically controls the inside
temperature, the air delivery mode,
the air conditioning compressor, and the fan speed. When AUTO
appears in the display, the system is
in full automatic operation. If any
of the controls are manually
adjusted, the AUTO indicator turns
off in the display.
1. Press the AUTO button, if the
AUTO indicator does not
appear on the display.
2. Adjust the temperature to a comfortable setting between
72°F (22°C) and 75°F (24°C). Choosing the coldest or warmest
temperature setting will not
cause the system to heat or cool
any faster.
3. Let the system stabilize for a few minutes.
4. Adjust the air outlets or temperature.
In cold weather, the system starts in
the recirculation mode with the
fan off. As the engine warms up,
warm air is directed to the oor
outlets, before automatically
changing to bi-level mode with a
reduced fan speed.
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.

2008 - Pontiac G8 Owner Manual

By monitoring the solar radiation,
the air inside the vehicle and
air moving across the outside
sensor, the selected temperature
can be maintained while using
the AUTO mode by adjusting the
temperature, fan speed, and
air delivery system. The system
may also supply cooler air to
the side of the vehicle facing the
sun. The recirculation mode will also
be activated, as necessary. Do not
cover the sensors or the automatic
climate control system will not
work properly.
Remote Start Climate Control
Operation
For vehicles with the remote start
feature and it is activated, the climate
control system will automatically set
the temperature to 73°F (23°C).
When the ignition is turned to
ON/RUN the climate control system
heats and cools the inside of the
vehicle using the modes that were
set before the vehicle was turned off.
Personal Identity Keys
For vehicles with the Personal
Identity Key Locking System,
the system remembers the last
climate control settings used with
different keys.
When the unlock button is pressed,
the system remembers the key
and sets the climate control system
to the last settings used with that
key. SeeRemote Keyless Entry
(RKE) System Operation on
page 2-4.
Passenger Compartment
Air Filter
The vehicle has a passenger
compartment air lter that lters the
outside air entering the vehicle.
The lter removes contaminants,
such as pollen and dust. See your
dealer/retailer for more information.
Outlet Adjustment
The air outlets have adjustable
vanes to move up or down and left
or right to change the direction
of the airow. Use the thumbwheels
located near the air outlets on
the instrument panel, to shut off
the airow.
Operation Tips

Clear away any ice, snow or
leaves from the air inlets at
the base of the windshield that
may block the ow of air into
the vehicle.
Use of non-GM approved hood
deectors may adversely affect
performance of the system.
Keep the path under the front
seats clear of objects to help
circulate the air inside of
the vehicle more effectively.
Outside air is drawn into the
vehicle, unless recirculation mode
is selected.
