climate control SATURN AURA HYBRID 2008 User Guide

In AUTO mode the system cools and dehumidies the
air inside the vehicle. Also while in AUTO mode,
the system maximizes its performance by using
recirculation as necessary.
Heating:On cold days when using manual operation of
the automatic system, use oor mode to deliver air to
the oor outlets. To warm or cool the air delivered, push
the temperature buttons to the desired setting.
To use the automatic mode, turn the knob to AUTO and
adjust the temperature by pressing the temperature
buttons.
When the heater is in use, there might be slight noise or
vibration during Auto Stops. This is due to the coolant
circulation pump that continues to circulate heat through
the system during the engine Auto Stop.
The heater works best if the windows are kept closed.
h(Recirculation):Press the button to turn on
the recirculation mode. The air inside the vehicle
recirculates through the climate control system and the
vehicle, not from outside the vehicle. This mode is
helpful when trying to limit odors from entering
the vehicle and for maximum air conditioning
performance in hot weather. When the button ispressed, an indicator light above the button comes on.
The recirculation indicator light blinks three times if
recirculation is used in a mode in which it cannot
function. Only use this mode when it is needed for
comfort, since window fogging rapidly occurs if the air
conditioning compressor is not engaged.
Press this button to cancel the auto recirculation
feature. Each time the vehicle is started, the system
reverts to the auto recirculation function.
If recirculation is selected while in defrost, defog or oor
mode, the light on the button ashes three times and
then goes out to indicate that this is not allowed. This is
to prevent window fogging.
When the weather is cool or damp, operating the
system in recirculation for extended periods of time can
cause fogging of the vehicle’s windows. To clear the
fog, select either defog or defrost. Make sure the
air conditioning is on. Allow the air conditioning to run
automatically to help dehumidify the air.
N(Hybrid Air Conditioning):This setting balances
fuel economy and air conditioning comfort. When
hybrid A/C is used in warm weather, you may notice
more frequent auto stops and the cabin may be warmer
as compared to normal air conditioning.

Maximum Air Conditioning
On hot days, open the windows to let hot inside air
escape; then close them. This helps to 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
Cvent mode.
2. Select the highest fan speed.
3. Select
#air conditioning.
4. Select the
hrecirculation 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.
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 choose from
to clear fog or frost from the 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.
-(Defog):Turn the mode knob to this position to
select the defog setting, which delivers air to the oor
and windshield outlets. Use this setting to clear the
windows of fog or moisture.
0(Defrost):Turn the mode knob to this position to
defrost the windshield. The system automatically
controls the fan speed if defrost is selected from the
AUTO mode. If the outside temperature is 40°F (4°C) or
warmer, the air conditioning compressor automatically
runs to help dehumidify the air and dry the windshield.
The air conditioning indicator light blinks three times
if the compressor is turned off while in this mode.
The engine will not perform Auto Stops when the defrost
mode is on.

Treadwear
The treadwear grade is a comparative rating based
on the wear rate of the tire when tested under
controlled conditions on a specied government
test course. For example, a tire graded 150 would
wear one and a half (1.5) times as well on the
government course as a tire graded 100. The
relative performance of tires depends upon the
actual conditions of their use, however, and may
depart signicantly from the norm due to variations
in driving habits, service practices, and differences
in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA,
A, B, and C. Those grades represent the tire’s
ability to stop on wet pavement as measured under
controlled conditions on specied government test
surfaces of asphalt and concrete. A tire marked C
may have poor traction performance.
Warning
:The traction grade assigned to
this tire is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
Temperature – A, B, C
The temperature grades are A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a
specied indoor laboratory test wheel. Sustained
high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance
which all passenger car tires must meet under
the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel
than the minimum required by law.
Warning
:The temperature grade for this
tire is established for a tire that is properly
inated and not overloaded. Excessive speed,
underination, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.

5. Plug the air compressor accessory plug (C) into
an accessory power outlet in the vehicle.
SeeAccessory Power Outlet(s) on page 3-18
for more information.
Do not slam door or close window on the
compressor accessory plug.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). SeeEngine
Exhaust on page 2-32.
6. Start the vehicle. SeeStarting the Engine
(Automatic Engine Start/Stop) on page 2-21
for more information. The vehicle must be
running while using the air compressor.
{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions, and
inate the tire to its recommended pressure.
Do not exceed 36 psi (248 kPa).
7. Push the On/Off kit switch to the I (on) position.
The sealant and compressor kit injects sealant
and air into the tire. Sealant could leak from
the puncture hole until the vehicle is driven and
the hole has sealed.
The pressure gage will initially show a high pressure
while the compressor injects the sealant into the
tire. Once the sealant is completely dispersed into
the tire, the pressure will quickly dropped and
start to rise again as the tire inates with air.

7. Push the sealant and compressor kit switch to
the I (on) position.8. Inate the tire up to the recommended ination
pressure using the air pressure gage on the top
of the unit.
9. Turn off the air compressor by moving the switch
to the O (off) position.
The pressure gage reads high while the compressor
is running. Turn the compressor off to get an
accurate reading. SeeInflation - Tire Pressure
on page 5-52for more information.
10. Disconnect the compressor inator hose and
wrap the hose in the bottom of the sealant and
compressor kit.
{CAUTION:
Storing the tire sealant and compressor
kit or other equipment in the passenger
compartment of the vehicle could cause injury.
In a sudden stop or collision, loose equipment
could strike someone. Store the tire sealant
and compressor kit in the proper place.
11. Place the equipment in the original location in
the trunk of your vehicle.
