2007 SATURN AURA HYBRID heating

Lockout Protection
This feature prevents the driver’s door from being
locked using the power door locks, if the key is
left in the ignition and a door is open.
Press the power door lock switch to lock all the
doors and then unlock the driver’s door.
Press and hold the power door lock switch for
more than three seconds to override this feature.
If the key is removed from the ignition, or if
the manual door lock or the Remote Keyless Entry
(RKE) transmitter is used, the key could still be
locked inside the vehicle. Always remember
to take the key with you.
Trunk
To open the trunk from the outside, press the
trunk release button on the Remote Keyless
Entry (RKE) transmitter.
{CAUTION:
It can be dangerous to drive with the
trunk lid open because carbon monoxide
(CO) gas can come into your vehicle. You
cannot see or smell CO. It can cause
unconsciousness and even death. If you
must drive with the trunk lid open or if
electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that will
force outside air into your vehicle. See
Climate Control System.
If you have air outlets on or under
the instrument panel, open them all
the way.
SeeEngine Exhaust on page 123.

Climate Controls
Automatic Climate Control System
You can automatically control the heating, cooling,
and ventilation in your vehicle.
Climate Control Inuence on Hybrid
Operation and Fuel Economy
The climate control system is dependent upon other
vehicle systems for heat and power input. Certain
climate control settings can lead to higher fuel
consumption and/or fewer Auto Stops.The following are climate control settings that use
more fuel:
Normal air conditioning mode.
The defrost mode.
Extreme temperature settings, such as 60°F
(15°C) / 90F (32°C).
High fan speed settings.
The following can help reduce fuel consumption:
Use of the full automatic control method as
described under Automatic Operation.
Use hybrid air conditioning, instead of the
normal air conditioning.
Select a temperature setting that is higher in
hot weather and lower in cold weather.
Only use defrost to clear the windows.
These suggestions will help to reduce fuel
consumption, but may reduce overall comfort.

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.
272

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.
275

{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 fans
are running. If the engine is overheating, both fans
should be running. If they are not, your vehicle
needs service.Notice:Engine damage from running your
engine without coolant is not covered by your
warranty.
Notice:Using coolant other than DEX-COOL®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant could require changing sooner, at
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.

Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and where
to obtain service, see your Saturn Warranty
booklet for details. For additional information refer
to the tire manufacturer’s booklet included with
your vehicle.
{CAUTION:
Poorly maintained and improperly used
tires are dangerous.
Overloading your vehicle’s tires can
cause overheating as a result of too
much friction. You could have an
air-out and a serious accident. See
Loading Your Vehicle on page 242.
CAUTION: (Continued)
CAUTION: (Continued)

Underinated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked when
your vehicle’s tires are cold. See
Inflation - Tire Pressure on page 304.
Overinated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a
pothole. Keep tires at the
recommended pressure.
Worn, old tires can cause accidents. If
the tire’s tread is badly worn, or if
your vehicle’s tires have been
damaged, replace them.
