2008 SATURN SKY air conditioning

Climate Controls
Climate Control System
The heating, cooling, and ventilation of the vehicle can
be controlled with this system. Set the control
between modes to get a combination of the two modes.
Temperature:Turn the left knob on the control panel
to adjust the temperature of the air in the vehicle.
Turn the knob clockwise or counterclockwise to increase
or decrease the temperature.
#(Air Conditioning):Press the left knob on the
control panel to turn the air conditioning system
on or off. An indicator light on the button comes on
to show that the air conditioning is activated.
When the system is on, this setting cools and
dehumidies the air entering the vehicle.
The air conditioning will not function if the fan is turned
off. If air conditioning is selected with fan off, the
indicator light ashes three times and then turns off.
There could be a slight change in engine performance
when the air conditioning compressor turns off and turns
on again. This is normal. The system is designed to
make adjustments to help with fuel economy while still
maintaining the selected temperature.
The air conditioning system removes moisture from the
air, so a small amount of water can drip underneath
your vehicle while idling or after turning off the engine.
This is normal.
Air conditioning does not operate at temperature
below 40°F (4°C). In temperatures above 40°F (4°C),
the air conditioning cannot be turned off in defrost,
oor/defog, and recirculation modes because it helps to
remove moisture from the vehicle. It also helps to
keep the windows clear.

On hot days, open the windows to let the hot inside air
escape; then close them. This helps reduce the time
it takes for the 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 recirculation mode.
3. Select the air conditioning to on.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
can 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.
9(Fan):Turn the center knob on the control panel to
control the fan speed. Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
9(Off):Turn the center knob to this position to turn
the fan off.
?(Recirculation):Press the center knob on the
control panel to recirculate air inside the vehicle
and prevent outside air from coming in. It can be used
to prevent outside odors from entering the vehicle
and cool the air inside the vehicle more quickly.Press this button to turn the recirculation mode on or
off. An indicator light on the button comes on while the
recirculation mode is activated.
Recirculation is available in the bi-level and vent modes.
If recirculation is selected in either oor/heat, oor/defog,
or defrost mode, the indicator light ashes three times
indicating it is not available in that mode.
The right knob on the control panel is used to direct the
airow inside the vehicle. Turn the knob to select one
of the following modes:
H(Vent):Turn the right knob on the control panel to
this mode to direct air to the instrument panel outlets.
\(Bi-Level):Turn the right knob on the control panel
to this mode to direct air to the instrument panel, oor,
defroster and side window outlets. Cooler air is directed
to the upper outlets and warmer air to the oor outlets.
[(Floor):Turn the right knob on the control panel to
this mode to direct most of the air to the oor outlets.
The remaining air is directed to the side window
and defroster outlets. If low or no airow is on the
passenger side, make sure that the carpet covering is
tucked under oor outlets.

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 and side windows. 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. Use a temperature setting that provides warm
air. The warmer the air the quicker the windows clear.
To prevent fogging on the inside of the windows in
modes other than oor/defog and defrost, make sure
the air conditioning compressor is on and recirculation
mode is off.
/(Floor/Defog):Turn the right knob on the control
panel to this mode to direct the air to the windshield, the
side window outlets, and to the oor outlets. When this
mode is selected, the system runs the air conditioning
compressor unless the outside temperature is near
freezing or below.
0(Defrost):Turn the right knob on the control panel to
this mode to direct most of the air to the windshield, and
the side window outlets. When this mode is selected, the
system runs the air conditioning compressor unless the
outside temperature is near or below freezing.
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 or frost from the rear window. Be sure to
clear as much snow from the rear window as possible.
An indicator light on the knob comes on while the
rear window defogger is activated. The rear window
defogger turns off about fteen minutes after the knob is
pressed. If turned on again, the defogger will run for
about seven and one-half minutes before turning off.
If vehicle speed is greater than 50 mph (80 kph) and the
rear defogger is active, it will remain on as long as
the speed is greater than 50 mph (80 kph). The defogger
can also be turned off by pressing the knob again or
by turning off the engine.
Do not use the rear defogger when the convertible top
is down.
=(Rear Defogger):Press the right knob on the
control panel to turn the rear window defogger on or off.
Do not use the rear defogger when the convertible
top is down.
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 air outlets located in the center and on the side
of your instrument panel to direct the airow.
Use the tab located on the air outlets to change the
direction of the airow.
Your vehicle has ow through ventilation that allows
outside air to be forced through your ventilation system
when your vehicle is moving. Outside air will enter
the vehicle when the air conditioning fan is running.
Flow through ventilation can be stopped in vent
and bi-level modes by pressing the recirculation button.
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-Saturn 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 of your vehicle more
effectively.
Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages on
your vehicle.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As the
details show on the next few pages, some warning lights
come on briey when you start the engine just to let you
know they are working. If you are familiar with this
section, you should not be alarmed when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
as you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s
advice. Waiting to do repairs can be costly and even
dangerous. So get to know your vehicle’s warning lights
and gages. They can be a big help.

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and rotors for surface
condition. Inspect drum brake linings/shoes for wear or
cracks. Inspect other brake parts, including drums,
wheel cylinders, 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, chafing, etc.
(c)Visually inspect hoses and have them replaced if
they are cracked, swollen, or deteriorated. Inspect
all pipes, fittings, and clamps; replace with genuine 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.
(d)Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and wiper blades,
if contaminated. Replace wiper blades that are worn
or damaged. See Windshield Wiper Blade Replacement
on page 5-49andWindshield and Wiper Blades on
page 5-89for more information.(e)Make sure the safety belt reminder light and safety
belt assemblies are working properly. Look for any
other loose or damaged safety belt system parts.
If you see anything that might keep a safety belt system
from doing its job, have it repaired. Have any torn or
frayed safety belts replaced. Also see Checking the
Restraint Systems on page 1-50.
(f)Lubricate all key lock cylinders. Lubricate all hinges
and latches, including those for the body doors, hood,
secondary latch, pivots, spring anchor, release pawl, rear
compartment, glove box door, and console door. More
frequent lubrication may be required when exposed to a
corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth will make them last
longer, seal better, and not stick or squeak.
(g)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.
(h)If you drive regularly under dusty conditions, inspect
the filter at each engine oil change.
(i)Drain, flush, and refill cooling system. This service
can be complex; you should have your dealer/retailer
perform this service. See Engine Coolant on page 5-24
for what to use. Inspect hoses. Clean radiator,
condenser, pressure cap, and filler neck. Pressure test
the cooling system and pressure cap.
