Climate Controls 7-3
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

What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean
your skin and nails with soap andwater, or a good hand cleaner.
Wash or properly dispose of clothing
or rags containing used engine
oil. See the manufacturer’s warnings
about the use and disposal of oil
products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the lter before disposal.
Never dispose of oil by putting it in
the trash, pouring it on the
ground, into sewers, or into streams
or bodies of water. Instead,
recycle it by taking it to a place that
collects used oil. If you have a
problem properly disposing of used
oil, ask your dealer/retailer, a
service station, or a local recycling
center for help.
