2007 PONTIAC GRAND PRIX air conditioning

3. Put the two halves back together. Make sure
the cover is on tight so water will not get
inside the transmitter.
4. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote start feature.
This feature allows you to start the engine
from outside the vehicle. It may also start the
vehicle’s heating or air conditioning systems and
rear window defogger. When the remote start
system is active, the climate control system will
heat or cool the inside of the vehicle based on the
outside temperature. The rear window defogger
will be turned on by the climate control system
when it is heating the inside of the vehicle. Normal
operation of the system will return after the key
is turned to RUN.
Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using remote start to have
the vehicle in view when doing so. Check local
regulations for any requirements on remote starting
of vehicles.Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.
The remote start feature provides two separate
starts per ignition cycle, each with 10 minutes of
engine running time.
The remote start system needs to be reset after
your vehicle’s engine is started two times using the
transmitter’s remote start button. The remote
start system is reset by inserting the vehicle’s key
into the ignition switch and turning to RUN.
SeeIgnition Positions on page 105for information
regarding the ignition positions on your vehicle.
Your remote keyless entry transmitter with
the remote start button provides an increased
range of operation. You can start your vehicle from
about 492 feet (150 m) away. However, the
range may be less while the vehicle is running,
and as a result you may need to be closer to your
vehicle to turn it off than you were to turn it on.
There are other conditions which can affect
the performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 86for
additional information.

(Fan):Turn the knob by this symbol, located on
the left side of the climate control panel, clockwise
or counterclockwise to increase or decrease the fan
speed. The fan speed will be temporarily reduced
between the transition to a new mode. The fan will
resume the original speed when the transition to the
new mode is complete.
9(Off):Turn the knob to this position to turn the
climate control system off. Only the heated seat
and/or rear defrost can be operated when the fan
is off.
Mode
Turn the middle knob to select the following modes:
H(Vent) (Outside Air):This mode directs
outside air to the instrument panel outlets. If driving
in city traffic, and the vehicle is stopped and
idling, or the weather is hot, press the recirculation
button. To prevent the air inside the vehicle
from becoming stale, be sure to turn off
recirculation periodically.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets, and the remaining
air to the oor outlets. Some air may be directed
toward the windshield. Slightly cooler air is directed
to the instrument panel outlets and warmer air is
directed to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed toward
the side window outlets and a little air directed to
the windshield.
In this mode, the system will automatically use
outside air. The air conditioning compressor will
be engaged unless the outside temperature
is 40°F (4°C) or below.
Recirculation cannot be selected when in this
mode even though the indicator light comes on
when the recirculation button is pressed.
The middle knob on the climate control panel can
also be used to select the defog or defrost mode.

Defogging and Defrosting
Fog on the inside of the vehicle is a result of high
humidity causing moisture to condense on the cool
window glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear frost or fog from the windshield.
Use the defog mode to clear the windows of
condensation and to warm the vehicle’s occupants.
Use the defrost mode to remove frost or
condensation from the windshield quickly.
See “Rear Window Defogger” later in this section
for information on clearing the rear window of
fog or ice.
.(Floor/Defog):Use the oor/defog mode to
clear the windows of fog or moisture and to
warm the passengers. This mode directs the air
equally between the windshield and the oor
outlets, along with some directed to the side
window outlets.
This mode will automatically use outside air. The
air conditioning compressor will be engaged
unless the outside temperature is 40°F (4°C) or
below. Recirculation cannot be selected when
in this mode even though the indicator light comes
on when the recirculation button is pressed.
1(Defrost):Use the defrost mode to remove
fog or frost from the windshield more quickly. This
mode directs most of the air to the windshield
and the side window outlets, with some air directed
to the oor outlets. This mode has a timer and
will shut off after ve minutes.
This mode will automatically use outside air. The
air conditioning compressor will be engaged
unless the outside temperature is 40°F (4°C) or
below. Recirculation cannot be selected when
in this mode even though the indicator light comes
on when the recirculation button is pressed.
Temperature
The knob on the right of the climate control panel
is the temperature adjustment that can be used
with any of the climate control modes.
Turn the knob clockwise for warmer settings and
counterclockwise for colder settings.

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 147for
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 ve 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.
160

6(Floor):This mode directs most of the air to
the oor outlets with some air directed to the
side window outlets, and a little air directed to the
windshield.
#(Air Conditioning):Press this button to turn
the air conditioning compressor on or off. The
indicator light on the button will come on when the
air conditioning is on.
?(Recirculation):Press this button to turn
the recirculation mode on or off. This mode keeps
outside air from coming in the vehicle. It can be
used to help reduce the outside air and odors that
may enter the vehicle or help to cool the air
inside the vehicle quicker.
Recirculation is not available in defrost or
oor/defog mode. Pressing the recirculation button
will turn on the indicator light.
Using recirculation for long periods of time may
cause the air inside your vehicle to become
too dry. To prevent this from happening, after the
air in your vehicle has cooled, turn the
recirculation mode off.
z(Heated Seats):Press this button to turn the
heated seats on and off. The button on the left
controls the driver’s seat and the button on
the right controls the passenger’s seat. See
Heated Seats on page 10for additional
information.
Sensors
The solar sensor on your vehicle monitors the
solar radiation and the air inside of your vehicle,
then uses the information to maintain the selected
temperature by initiating needed adjustments to
the temperature, the fan speed and the 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 solar sensor located
in the center of the instrument panel, near the
windshield, or the system will not work properly.

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 clear fog or frost from your
windshield. Use the oor/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.
-(Floor/Defog):This mode directs the air
between the windshield, oor outlets and side
windows. When you select this mode, the system
turns off recirculation and runs the air-conditioning
compressor unless the outside temperature is near
or below freezing. Pressing the recirculation button,
while in this mode, will have no effect other than
turning on the indicator light.
1(Defrost):This mode directs most of the air to
the windshield, with some air directed to the side
windows. In this mode, the system will
automatically turn off the recirculation and run the
air conditioning compressor, unless the outside
temperature is near or below freezing. Pressing the
recirculation button, while in this mode, will have no
affect other than turning on the indicator light.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
engine is running.
=(Rear Window Defogger):Press this button
to turn the rear window defogger on and off. Be
sure to clear as much snow from the rear window
as possible.
The rear window defogger will turn off about
20 minutes after the button is pressed. If turned
on again, the defogger will only run for about
20 minutes before turning off. The defogger can
also be turned off by pressing the button again or
by turning off the engine.
Do not drive the vehicle until all the windows are
clear.
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.
