Air Conditioning - Pontiac Grand Prix 2007 Owner's Manual

Air Conditioning

#
(Air Conditioner): Press this button to
turn the air conditioning compressor on or off.
An indicator light to the right of the button
will come on. This button has no control over the
air conditioning compressor when in Floor/Defog
and Defrost modes. The instrument panel
brightness control may have to be adjusted to
the highest setting in order to see the indicator.
See Instrument Panel Brightness on page 151
for additional information.
On hot days during the vehicle's initial start-up,
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 quicker cool down on hot days, do the following:
1. Select any mode setting between vent and
the setting before defrost.
2. Select the air conditioner.
3. Select the coolest temperature.
4. Select the highest climate control fan speed.

Using these settings will set recirculation for
quicker cool down (the light indicator will not turn
on). If outside air is desired, press the recirculation
button twice.
Using these settings together for long periods of
time may cause the air inside the vehicle to become
too dry. To prevent this from happening, after
five minutes the recirculation door will open slightly
to allow some outside air into the vehicle.
The air conditioning system removes moisture
from the air, so sometimes there may be a
small amount of water dripping underneath the
vehicle while it is idling or after the engine is turned
off. This is normal.
Recirculation
h
(Recirculation): Press this button to activate
the recirculation mode. With this selection,
inside air is recirculated into the vehicle. This
mode reduces outside air and odors from entering
the vehicle. It may also help to heat or cool the
air inside the vehicle more quickly.
