2005 CHEVROLET MONTE CARLO air conditioning

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling,
defrost, defog and ventilation for your vehicle.
Manual Operation
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode allows for approximately a
50/50 split of air to the instrument panel outlets and
to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets, with some of the air directed to the
windshield and side window outlets. In this mode, the
system will automatically select Outside Air.
The right knob can also be used to select defog or
defrost mode. For more information, see “Defogging and
Defrosting” later in this section.
By positioning the right knob between two modes, a
combination of those two modes is selected.
It should be noted, that the air conditioning compressor
will be engaged unless the outside temperature is
40°F (4°C) or below. Recirculation cannot be selected
when in Floor Mode.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
If the airow seems low when the fan is at the highest
setting, the passenger compartment air lter, if
equipped, may need to be replaced. For more
information, seePassenger Compartment Air Filter on
page 3-25andScheduled Maintenance on page 6-4.

:(Outside Air):Press this button to turn the
outside air mode on. When this mode is on, outside air
will circulate throughout your vehicle. When the
button is pressed, an indicator light in the button 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.
You may have to set the instrument panel brightness
control to the highest setting during the day to see
the indicator lamp.
?(Recirculation):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 help heat or
cool the air inside your vehicle more quickly. Press this
button to turn the recirculation mode on. When the button
is pressed, an indicator light will come on.
You may have to set the instrument panel brightness
control to the highest setting during the day to see the
indicator lamp.
The recirculation mode cannot be used with outside air
modes.
D or P (Temperature Control):Slide the levers
marked D (Driver) or P (Passenger) to increase or
decrease the temperature on the driver’s side or
the passenger’s side of the vehicle.
#(Air Conditioning):Press this button to turn the
air conditioning system on or off. When A/C is pressed,
an indicator light will come on to let you know that
the air conditioning has been activated.
You may have to set the instrument panel brightness
control to the highest setting during the day to see
the indicator lamp.
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 recirculation mode.
3. Select A/C.
4. Select the coolest temperature for both zones.
5. Select the highest fan speeds.
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 inside of 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.
3-23

Defogging and Defrosting
Fog on the inside of the 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 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 clockwise to select the defog or
defrost mode.
-(Defog):This mode directs air equally to the
windshield and the oor outlets. When you select this
mode, the system turns off recirculation and runs the air
conditioning compressor unless the outside temperature
is below 40°F (4°C). The recirculation mode cannot
be selected while in the defog mode.
Do not drive the vehicle until all the windows are clear.
0(Defrost):This mode directs half of the air to the
windshield and side window vents and half to the oor
vents. In this mode, the system will automatically force
outside air into your vehicle. The recirculation mode
cannot be selected while in the defog mode. The air
conditioning compressor will run automatically in this
setting, unless the outside temperature is
below 40°F (4°C).
Do not drive the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<:The rear window defogger will turn off
approximately 20 minutes after the button is pressed. If
turned on again, the defogger will run for the same
amount of time. 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.
If your vehicle has heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
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.

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.

Maintenance Footnotes
†The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chang, etc. Inspect
disc brake pads for wear and rotors for surface
condition. Inspect other brake parts, including calipers,
parking brake, etc.(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing parts or
signs of wear. Inspect power steering lines and hoses
for proper hook-up, binding, leaks, cracks, chang, etc.
(c)Visually inspect hoses and have them replaced if they
are cracked, swollen, or deteriorated. Inspect all pipes,
ttings, and clamps; replace with genuine GM parts as
needed. To help ensure proper operation, a pressure test
of the cooling system and pressure cap and cleaning the
outside of the radiator and air conditioning condenser is
recommended at least once a year.
