coolant temperature SATURN AURA 2007 Owners Manual

The engine is required to run for either heater
or climate control performance. See “Air
Conditioning Engine Start/Stop” under
Automatic Climate Control System on
page 154for more information.
The hybrid battery pack charge is low and
requires recharging.
Auto Stop time is greater than two minutes.
Engine Coolant Heater
Your vehicle may have this feature. In very cold
weather, 0°F (−18°C) or colder, the engine coolant
heater can provide easier starting and better
fuel economy during engine warm-up. Usually, the
coolant heater should be plugged in a minimum
of four hours prior to starting your vehicle. At
temperatures above 32°F (0°C), use of the coolant
heater is not required. Your vehicle may also
have an internal thermostat in the plug end of the
cord. This will prevent operation of the engine
coolant heater when the temperature is at or above
0°F (−18°C) as noted on the cord.

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 264for 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
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 your
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 temperaturesetting 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.

On cool, but sunny days while using manual
operation of the automatic system, use bi-level to
deliver warm air to the oor and cooler air to
the instrument panel outlets. To warm or cool the
air delivered, press the temperature buttons to
the desired setting.
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 your 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 is pressed, 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 you select recirculation while in defrost, defog or
oor, 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.

Automatic Transaxle Fluid
It is not necessary to check the transaxle uid
level. A transaxle uid leak is the only reason for
uid loss. If a leak occurs, take your vehicle to
the retailer service department and have it repaired
as soon as possible.
Change the uid at the intervals listed inAdditional
Required Services on page 359, and be sure to
use the transaxle uid listed inRecommended
Fluids and Lubricants on page 365.
Notice:Use of the incorrect automatic
transaxle uid may damage your vehicle, and
the damages may not be covered by your
warranty. Always use the automatic transaxle
uid listed inRecommended Fluids and
Lubricants on page 365.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 275.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F
(−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.

Adding Coolant
If you need more coolant, add the proper
DEX-COOL®coolant mixture at the surge tank,
but only when the engine is cool. If the surge tank
is empty, a special ll procedure is necessary.
SeeEngine Overheating on page 275andCooling
System on page 278.
{CAUTION:
You can be burned if you spill coolant on
hot engine parts. Coolant contains
ethylene glycol, and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
SeeEngine Compartment Overview on page 264
for more information on location.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
You will nd an engine coolant temperature
warning light on your vehicle’s instrument panel.
SeeEngine Coolant Temperature Warning
Light on page 171for more information.

2. Then keep turning the pressure cap slowly,
and remove it.
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
What to Use
When you need windshield washer uid, be sure
to read the manufacturer’s instructions before
use. If you will be operating your vehicle in an area
where the temperature may fall below freezing,
use a uid that has sufficient protection against
freezing.
