2008 CHEVROLET AVEO air conditioning

Temperature Control:Turn the left knob clockwise or
counterclockwise to manually increase or decrease the
temperature inside the vehicle. Turn the knob to the blue
area for cool air and to the red area for warm air.
9(Fan):Turn the middle knob clockwise or
counterclockwise to increase or decrease the fan speed.
In any setting other than off, the fan will run continuously
with the ignition on. The fan must be on in order for
the air conditioning compressor to run.To change the current mode, select one of the following
from the right knob:
Y(Vent):This mode directs air to the instrument panel
outlets.
\(Bi-Level):This mode directs about half of the air
to the instrument panel outlets, and then directs the
remaining air to the floor outlets.
[(Floor):This mode directs most of the air to the floor
outlets. Some of the air will also be directed to the rear
outlets. Be sure to keep the area under the front seats
clear to allow the flow of air to the rear compartment.
The right knob can also be used to select the defog and
defrost modes. Information on defogging and defrosting
can be found later in this section.
?(Recirculation):This mode keeps outside air
from coming into the vehicle. It can be used to prevent
outside air and odors from entering the vehicle or to
help heat or cool the air inside the vehicle more quickly.
If your vehicle has a recirculation button (uplevel
model), press the button to turn the recirculation mode
on. When the button is pressed, an indicator light in
the button comes on. Press the button again to return
to outside air mode. Uplevel shown, Base similar, Sedan only
3-21

If your vehicle has a lever (base model), move the lever
to choose the recirculation mode.
Using the recirculation mode for extended periods may
cause your windows to fog. If this happens, select
the defrost mode.
:(Outside Air):This mode brings outside air into
the vehicle.
If your vehicle has a recirculation button (uplevel
model), press the button until the recirculation mode
is turned off. Your vehicle will then return to outside
air mode.
If your vehicle has a lever (base model), move the lever
to choose the outside air mode.
A/C (Air Conditioning):If your vehicle has air
conditioning, follow these steps to use the system.
Start the engine and set the fan control knob to
the desired speed. The air conditioning compressor
does not operate when the fan control knob is in the
off position. Press the A/C button to turn the air
conditioning compressor on and off. When the A/C
button is pressed, an indicator light in the button
comes on to show 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. Press the A/C button.
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 the vehicle to become too dry.
To prevent this from happening, after the air in the vehicle
has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from the
air, so a small amount of water might drip underneath
the 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
or 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.
For best results, clear all snow and ice from the
windshield before defrosting.
Select one of these available modes from the right knob.
É(Defog):This mode directs most of the air to the
windshield and the floor outlets. A small amount of air is
also directed to the outboard outlets for the side windows
and to the instrument panel side outlets. When this
mode is selected, the system runs the air-conditioning
compressor. To defog the windows faster, turn the
temperature control knob clockwise to the warmest
setting.
1(Defrost):This mode directs the air to the
windshield and the outboard outlets for the side windows.
A small amount of air is also directed to the instrument
panel side outlets. When this mode is selected, the
system runs the air-conditioning compressor. To defrost
the windows faster, turn the temperature control knob
clockwise to the warmest setting.
Do not drive the vehicle until all windows are clear.
Rear Window and Outside Mirror
Defogger
Your vehicle may have a rear window and outside
mirror defogger. This feature only works when
the ignition is turned to ON/RUN.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Before
using this feature, clear as much snow from the
rear window as possible.
<(Rear Window Defogger):Press this button to
turn the rear window and outside mirror defogger on
or off. An indicator light in the button comes to show
that the feature is activated.
If your vehicle does not have air conditioning, the rear
window defogger will remain on until the button is
pressed again or the engine is turned off.
If your vehicle has air conditioning, the rear window
defogger will turn off about 10 minutes after the button
is pressed. The defogger can also be turned off by
pressing the button again or by turning the engine off.
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.

{CAUTION:
An electric engine cooling fan under the hood
can start up even when the engine is not
running and can injure you. Keep hands,
clothing, and tools away from any underhood
electric fan.
If the coolant inside the coolant surge tank is boiling,
do not do anything else until it cools down. To check the
engine coolant, the vehicle should be parked on a
level surface. Make sure that the air conditioning
is turned off.
The coolant level should be between the Minimum and
Maximum marks on the coolant surge tank when the
engine is cool. If it is not, you may have a leak at
the pressure cap or in the radiator hoses, heater hoses,
radiator, water pump, or somewhere else in the
cooling system.
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them.
If you do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine re, and you could be
burned. Get any leak xed before you drive
the vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fan is running.
If the engine is overheating, the fan should be running.
If it is not, your vehicle needs service.
Notice:Engine damage from running the engine
without coolant is not covered by the warranty.

rating is the maximum speed a tire is certified 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).

: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.
Belt
:A rubber coated layer of cords that is

materials.
Bead
:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire
:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.
Cold Tire Pressure
:The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat
from driving. SeeInflation - Tire Pressure on
page 5-57.
