2008 SATURN VUE HYBRID cooling

The Engine Will Remain Running When:

The engine, transmission, or hybrid battery is
not warmed up yet.
The outside temperature is high — usually above
95°F (35°C) and the climate control system is
working to cool the vehicle in A/C mode (yellow light
illuminated on A/C button) or if defrost is selected.
SeeAutomatic Climate Control System on
page 3-18for more information.
The shift lever is in PARK (P), REVERSE (R),
NEUTRAL (N), MANUAL MODE (M).
The hybrid battery pack charge is low.
The 12V vehicle battery charge is low, or loads
are high.
The hood is not fully closed.
The Engine Will Restart When:

The brake pedal is released.
The accelerator pedal is applied.
When shifting from DRIVE (D) to PARK (P),
REVERSE (R), NEUTRAL (N), MANUAL MODE (M)
the engine will restart immediately.
If the A/C button (green light illuminated on A/C)
button is selected, the duration of the AUTO
STOP will depend on the outside temperature.
This economy mode improves fuel economy
by limiting the effects of the air conditioning.
The warmer it is outside, the shorter the time before
the engine is restarted to provide cabin cooling.
The climate control system is turned from Off to
On (econ or normal A/C, or oor/ defog/defrost). See
Automatic Climate Control System on page 3-18for
more information.
The engine is required to run for either heater or
climate control performance. See “Air Conditioning
and Engine Start/Stop” underAutomatic Climate
Control System on page 3-18for more information.
The hybrid battery pack charge is low and requires
recharging.
Auto Stop time is greater than two minutes.

Climate Controls
Automatic Climate Control System
The heating, cooling, and ventilation for the vehicle can
be controlled with this system.
Climate Control Inuence on Hybrid
Operation and Fuel Economy
To maximize your fuel economy, use the following
settings:
Set the fan knob to AUTO.
Set the air delivery knob to AUTO.
Select an air temperature setting near 75°F (23°C).
Select the Hybrid A/C button, if A/C is required.Avoid using these settings that may lead to fewer auto
stops and to higher fuel consumption:
Manual fan speed operation.
Defrost mode. Only use this setting to clear the
windows.
Extreme cold or hot air temperature settings, such
as 60°F (16°C) or 90°F (32°C).
Normal air conditioning mode, if A/C is required.
Automatic Operation
This climate control system automatically maintains the
desired temperature inside the vehicle.
Do not cover the sensor located on the top of the
instrument panel near the windshield or the sensor grille
below the climate control faceplate. These two sensors
help regulate the inside air temperature.
AUTO (Automatic Fan):Turn the fan knob to AUTO
for the system to automatically adjust the fan speed
to reach the desired inside temperature.
Temperature Control:Select the desired air
temperature between 60-90°F (16-32°C). Typically,
the best setting is near 75°F (23°C). Choosing the
coldest or warmest temperature setting does not
cause the system to heat or cool any faster.

To change the current air delivery mode, use the right
knob to select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode divides the air between the
instrument panel outlets and the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the windshield.
When this mode is selected, the system turns the
recirculation mode off. Recirculation mode cannot be
selected while in oor mode. This is to help prevent
window fogging.
The right knob can also be used to select defog or
defrost mode. See “Defogging and Defrosting” later in
this section.
#(Normal Air Conditioning):Press this button to
turn the air conditioning system on or off. When this
button is pressed, an indicator light comes on to show
that the air conditioning is activated. Normal Air
Conditioning (A/C) can be selected in any mode as long
as the fan is on and the outside air temperature is above
freezing. Normal A/C cannot be selected at the same
time as Hybrid Air Conditioning (A/C). A ashing indicator
light indicates that the air conditioning compressor is
currently not available.When Normal A/C is selected, the climate control system
will prevent all automatic engine start/stop operations.
This will ensure the cabin comfort is maintained. See “Air
Conditioning and Automatic Engine Start/Stop” later in
this section.
N(Hybrid Air Conditioning):Press this button to
turn the Hybrid A/C system on or off. When this button is
pressed, an indicator light comes on to show that the
Hybrid A/C is activated. Hybrid A/C can be selected in
any mode, except defrost as long as the fan is on and the
outside air temperature is above freezing. Hybrid A/C
cannot be selected at the same time as the normal air
conditioning. A ashing indicator light indicates the air
conditioning compressor is not available.
The Hybrid A/C works to balance fuel economy and air
conditioning comfort. When Hybrid A/C is used in warm
weather, the vehicle gets better fuel economy by allowing
more frequent start/stops. For additional cooling, select
Normal A/C. See “Air Conditioning and Automatic Engine
Start/Stop” later in this section.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger will only work when the
ignition is in ON/RUN.
<(Rear Window Defogger):Press this button to
turn the rear window defogger on or off. An indicator
light on the button comes on to show that the rear
window defogger is activated.
The rear window defogger stays on for about 10 minutes
if the vehicle remains at slower vehicle speeds or until
the button is pressed, or unless the ignition is turned
to ACC/ACCESSORY or LOCK/OFF. If turned on again,
the defogger only runs for about ve minutes before
turning off again. At higher vehicle speeds, the defogger
may stay on continuously. The defogger can always
be turned off by pressing the button again or by turning
off the ignition.
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 the vehicle warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
Air Conditioning and Engine Start/Stop
On hot days, use the automatic fan and automatic air
delivery mode settings and the vehicle will reach the
desired temperature more quickly. The desired fan and
air delivery mode settings can still be adjusted manually.
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 and helps the system to operate
more efficiently.
When either the Normal A/C or Hybrid A/C modes are
active, the air conditioning system removes moisture
from the air, so a small amount of water may drip under
the vehicle while idling or after turning off the engine.
This is normal.
The use of Normal A/C causes the engine to keep
running while the vehicle is at a complete stop to allow
the climate control system to continue cooling.
The use of Hybrid A/C allows automatic engine start/
stop operations while the vehicle is at a complete stop.
The air conditioning compressor can not run when
the engine is not running, resulting in reduced cooling
performance. The climate control system may keep the
engine running or restart the engine during a stop to
continue cooling. Selecting the Normal A/C button forces
the engine and air conditioning compressor to restart
automatically. For more information about Engine
Start/Stop operation, seeStarting the Engine
(Automatic Engine Start/Stop) on page 2-18.

Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full?
Windows clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires inated
to recommended pressure?
Weather and Maps:Safe to travel?
Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, nd
a safe place to park your vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan the road ahead
and to the sides.
Check the rearview mirror and vehicle
instruments often.
Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep your vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a lower gear.
{CAUTION:
If you do not shift down, the brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let the engine assist the brakes on a steep
downhill slope.

3. When the chocks are in place, release the regular
brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake and shift into PARK (P).
5. Release the regular brakes.
When You Are Ready to Leave
After Parking on a Hill
1. Apply your regular brakes and hold the pedal
down while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store
the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you
are pulling a trailer. SeeScheduled Maintenance
on page 6-4for more information. Things that are
especially important in trailer operation are automatic
transmission uid (do not overll), engine oil, axle
lubricant, drive belt, cooling system and brake system.
Each of these is covered in this manual, and the
Index will help you nd them quickly. If you are trailering,
it is a good idea to review this information before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating
on page 5-23.

Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it
again, keeping the tip down and check the level.
