2006 PONTIAC GRAND PRIX air conditioning

2. Remove the old battery and replace it with the new
one. Make sure the positive side (+) of the battery
faces up. Use one three-volt, CR2032 battery,
or equivalent type.
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 2-22for 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 approximately
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 System on page 2-3for 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.
3-26

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 3-18for
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 light). If outside air is
desired, press the recirculation button (light indicator
will turn off).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.
An indicator light to the right of the button will come on to
show that the recirculation button has been pressed. The
instrument panel brightness control may have to be
adjusted to the highest setting to see the indicator.
The recirculation mode has a timer. After ve minutes,
the system’s air inlet door will move slightly to allow for
ten percent fresh outside air to maintain interior air
quality. The only way to reset the system to full
recirculation is to restart the ve minute timer by
selecting vent/outside air and recirculation again.

light on the button will come on when the air
conditioning is on.The indicator light on the air condition button will light
every time the vehicle is started. The air conditioner may
be turned off by pressing the air conditioner button.
?(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 prevent
outside air and odors from entering your vehicle or to help
cool the air inside your vehicle more quickly.
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. SeeHeated Seats on page 1-3for

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 defrost 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.

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
