coolant temperature SATURN AURA 2008 Owners Manual

Engine Coolant Heater
The engine coolant heater, if available, can help in
cold weather conditions at or below 0°F (−18°C)
for easier starting and better fuel economy during
engine warm-up. Plug in the coolant heater at least
four hours before starting your vehicle. An internal
thermostat in the plug-end of the cord may exist which
will prevent engine coolant heater operation at
temperatures above 0° F (−18° C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
engine coolant heater cord is located near the air
cleaner box on the passenger side of the engine
compartment. SeeEngine Compartment Overview
on page 5-14for more information on location.
3. Plug the cord into a normal, grounded 110-volt
AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord
will not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature,
the kind of oil you have, and some other things.
Instead of trying to list everything here, we ask that
you contact your dealer/retailer in the area where you
will be parking your vehicle. The dealer/retailer can
give you the best advice for that particular area.

Automatic Operation
AUTO (Automatic):Select AUTO on both the fan
speed knob and the air delivery mode knob to activate
the automatic system. When automatic operation is
active the system controls the inside temperature and
air delivery.
Use the steps below to place the entire system in full
automatic control:
1. Turn the fan knob and the mode knob to the AUTO
position.
The current set temperature displays. When AUTO
is selected, the air conditioning operation and air
inlet is automatically controlled. The air conditioning
compressor runs while the outside temperature is
over about 40°F (4°C). The air inlet is normally
set to outside air. If it is hot outside, the air inlet can
automatically switch to recirculate inside air to
help quickly cool down the vehicle.2. Set the temperature.
An initial setting of 73°F (23°C) is recommended.
Allow about 20 minutes for the system to regulate.
Press the
worxarrow temperature buttons
to adjust the temperature setting as necessary.
If the temperature is set at 60°F (15°C) the system
remains at the maximum cooling setting. If the
temperature is set at 90°F (32°C) the system
remains at the maximum heat setting. Choosing
either maximum setting does not cause the vehicle
to heat or cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield.
This sensor regulates air temperature based on the
intensity of the sun.
Also do not cover the sensor grille on the lower
right side of the climate control faceplate, as
this regulates the inside temperature.
To avoid blowing cold air at engine start-up in cold
weather, the system delays turning on the fan
until warm air is available. The length of delay
depends on the engine coolant temperature. Turning
the fan knob overrides this delay and changes
the fan to the selected speed.

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.

3. Fill the coolant surge tank with the proper mixture, to
the FULL COLD mark on the front of the surge tank.
Wait about ve minutes, then check to see if the level
is below the FULL COLD mark. If the level is below
the FULL COLD mark, add additional coolant to bring
the level up to the mark. Repeat this procedure until
the level remains constant at the FULL COLD mark
for at least ve minutes.
4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine cooling fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower than
the FULL COLD mark, add more of the proper
mixture to the coolant surge tank until the level
reaches the FULL COLD mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
See your dealer/retailer, if necessary.Windshield Washer Fluid
