2005 PONTIAC G6 air conditioning

Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside of the
vehicle. It also starts up the vehicle’s heating or air
conditioning systems and rear window defogger. When
the remote start system is active and the vehicle
has an automatic climate control system, it will
automatically regulate the inside temperature. Normal
operation of the system will return after the ignition
key is turned to the on position.
Laws in some communities may restrict the use of
remote starters, for example, requiring 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,
each with 10 minutes of engine running. Or it provides
one start with 10 minutes of engine running, which
can be extended by 10 more minutes. Once two starts
have been provided, the ignition switch must be
cycled to on and then off, to get two more remote starts.
The remote start feature will not operate if the key is
in the ignition, a door is open, the hood is not closed, the
hazard warning ashers are on, or two remote starts
have been provided without cycling the ignition switch to
on and then off.
Your remote keyless entry transmitter, with the remote
start button, provides an increased range of operation.
However, the range may be less while the vehicle
is running. 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 System on page 2-3.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle. If your vehicle has
the remote start feature, the climate control system will
function as part of the remote start feature. The system
will return to the last settings the vehicle was at when
it was turned off.
Operation
9
(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan
speed. The fan must be on to run the air-conditioning
compressor.
To change the air delivery settings, turn the right knob
to select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(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 side windows.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed to the side
window outlets.
The right knob can also be used to select defog or
defrost modes. Information on defogging and defrosting
can be found later in this section.
3-19

:(Outside Air):Press the right side of this button to
turn the outside air mode on. When this mode is selected,
air from outside the vehicle will circulate throughout your
vehicle. When the button is pressed, an indicator light will
come on to let you know that it is activated. The outside
air mode can be used with all modes, but it cannot be
used with the recirculation mode. Pressing this button will
cancel the recirculation mode.
?(Recirculation):Press the left side of the button to
turn the recirculation mode on. When recirculation mode
is selected, the air inside the vehicle will be recirculated
through the climate control system and the vehicle, not
from outside your vehicle. This mode is helpful when you
are trying to limit odors from entering your vehicle and for
maximum air conditioning performance in hot weather.
When the button is pressed, an indicator light above the
button will come on to let you know that it is activated.
The recirculation indicator light will blink three times if you
try to use recirculation in a mode that it can not be used
in. Only use this mode when it is needed for comfort,
since window fogging will rapidly occur if the air
conditioning compressor is not engaged.Pressing this button will cancel the outside air mode.
When you switch to the defog or defrost modes the
system will automatically move from recirculation to
outside air. When you move the mode knob back to
another air delivery mode, the system will move back into
recirculation. When the vehicle or fan is turned off and
back on, the system will default to outside air
automatically. Only use recirculation mode when it is
needed for comfort, since window fogging may occur.
Temperature Control:Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside your vehicle.
When it’s cold outside 0°F (−18°C) or lower, use the
engine coolant heater, if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warms
the coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
seeEngine Coolant Heater on page 2-23.

#(Air Conditioning):Press this button to turn the air
conditioning system on or off. When the air conditioning
button is pressed, an indicator light will come on to let you
know that air conditioning is activated.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your 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 vent 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
may cause the air inside of your vehicle to become
too dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.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):This mode splits the air between the
windshield and the oor outlets with a small amount
directed to the side windows. When you select this
mode, the system turns off recirculation automatically.
The air-conditioning compressor will run unless the
outside temperature is at or below freezing. The
air-conditioning compressor will operate although the
indicator light will not be on. The air-conditioning
indicator light will turn off when defog is selected.
If the air-conditioning button is pressed while in defog
mode, the indicator light will turn on. If the button
is pressed again, the light will turn 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):This mode directs most of the air to the
windshield with some air directed to the oor vents.
In this mode, the system will automatically force outside
air into your vehicle. The air-conditioning compressor
will run unless the outside temperature is at or below
freezing. The air-conditioning compressor will
operate although the indicator light will not be on.
The air-conditioning indicator light will turn off when
defrost is selected. If the air-conditioning button is
pressed while in defrost mode, the indicator light will
turn on. If the button is pressed again, the light will
turn 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 will come on
to let you know that the rear window defogger is
activated. Be sure to clear as much snow from the rear
window as possible.
If driving below 50 mph (80 kph), the rear window
defogger will turn off about 15 minutes after the button
is pressed. If turned on again, the defogger will only
run for about seven 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 will remain on once
the button is pressed.

Tire Size
The following illustration shows an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter P as the
rst character in the tire size means a passenger
vehicle tire engineered to standards set by the U.S. Tire
and Rim Association.
(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio:A two-digit number that indicates
the tire height-to-width measurements. For example, if
the tire size aspect ratio is 60, as shown in item C of
the illustration, it would mean that the tire’s sidewall is
60 percent as high as it is wide.(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire. The letter
R means radial ply construction; the letter D means
diagonal or bias ply construction; and the letter B means
belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:These characters represent
the load range and speed rating of the tire. The load
index represents the load carry capacity a tire is certied
to carry. The load index can range from 1 to 279. The
speed rating is the maximum speed a tire is certied
to carry a load. Speed ratings range from A to Z.
Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire pressing
outward on each square inch of the tire. Air pressure
is expressed in pounds per square inch (psi) or
kiloPascal (kPa).
Accessory Weight:This means the combined weight
of optional accessories. Some examples of optional
accessories are, automatic transmission, power steering,
power brakes, power windows, power seats, and air
conditioning.
Aspect Ratio:The relationship of a tire’s height to
its width.
