2005 CHEVROLET IMPALA air condition

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.
3-21

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.
3-22

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.
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.
Outlet Adjustment
Use the knob located below or to the side of the outlet,
to change the direction of the air ow.
Operation Tips
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside your vehicle more
effectively.
If the airow seems low when the fan is at the
highest setting, the passenger compartment
air lter, if equipped, may need to replaced. For
more information, seePassenger Compartment Air
Filter on page 3-25andScheduled Maintenance
on page 6-4.
If fogging reoccurs while in vent or bi-level modes
with mild temperature throughout the vehicle, turn
on the air conditioner to reduce windshield fogging.

This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible
