air condition CHEVROLET IMPALA 2006 9.G Owners Manual

Your vehicle has a feature that may automatically
unlock the doors and turn on the interior lamps and
hazard warning ashers when the airbags inate.
You can lock the doors again, turn the interior lamps,
and hazard warning ashers off by using the controls
for these features.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for
the airbag system. If you do not get them, the airbag
system will not be there to help protect you in
another crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
Your vehicle has a crash sensing and diagnostic
module which records information after a crash.
SeeVehicle Data Collection and Event Data
Recorders on page 7-9.
Let only qualied technicians work on the airbag
system. Improper service can mean that the
airbag system will not work properly. See your
dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system. The
passenger airbag status indicator on the instrument
panel will be visible when you turn your ignition key to
RUN or START. The words ON and OFF or the symbol
for on and off, will be visible during the system check.
When the system check is complete, either the word ON
or the word OFF, or the symbol for on or the symbol
for off will be visible. SeePassenger Airbag Status
Indicator on page 3-28.
The passenger sensing system will turn off the right front
passenger’s frontal airbag under certain conditions. The
driver’s airbag and the side impact airbags (if equipped)
are not part of the passenger sensing system.United States

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 3-23andScheduled 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.
?(Recirculation):Press this button to turn the
recirculation mode on. When the button is pressed, an
indicator light will come on.
This mode keeps outside air from entering the vehicle.
It can be used to prevent outside air and odors from
entering your vehicle. Recirculation may also help heat
or cool the air inside your vehicle more quickly once
the temperature inside the vehicle is equal to or better
than the outside temperature. The recirculation mode
cannot be used with outside air, oor, defrost, or
defogging modes.
Temperature Control:Rotate the thumbwheels up or
down to increase or decrease the temperature on
the driver’s side or the passenger side of the vehicle for
the dual zone system. Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature for the single zone system.
#(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.
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.
3-20

For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the outside air.
3. Select A/C.
4. Select the coolest temperature for both zones.
5. Select the highest fan speeds.
6. Once the vehicle’s interior temperature is below the
outside temperature, select recirculation mode for
enhanced cooling.
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. Do not drive the vehicle until all the
windows are clear.
-(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.
0(Defrost):This mode directs a portion of the air
to the windshield and side window vents and some
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).

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 automatically
after it has been activated. The duration the rear window
defogger is on will be longer if the vehicle is being driven.
The defogger can also be turned off by pressing the
button again or by turning off the engine.
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 thumbwheel 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 3-23andScheduled 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.
3-22

Charging System Light
The charging system light
will come on briey when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have
a problem with the charging system. It could indicate
that you have problems with a generator drive belt,
or another electrical problem. Have it checked
right away. Driving while this light is on could drain
your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as the
radio and air conditioner.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to RUN. If it does not come on then, have it
xed so it will be ready to warn you if there is a problem.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which monitors
operation of the fuel,
ignition, and emission
control systems.
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. SeeAccessories
and Modifications on page 5-3.
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.
