2007 CHEVROLET COBALT air conditioning

3. Snap the front and back together tightly so
moisture will not get inside the transmitter.
4. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote start feature.
This feature allows you to start the engine
from outside the vehicle. It may also start the
vehicle’s heating or air conditioning systems.
When you start your vehicle using the remote start
feature, the climate control system will come on
and adjust the interior to the temperature settings
that you left it set to when you turned the
vehicle off.
Laws in some communities may restrict the use
of remote starters. For example, some laws
may require a person using remote start to
have the vehicle in view when doing so. Check
local regulations for any requirements on remote
starting of vehicles.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.The remote start feature provides two separate
starts per ignition cycle, each with 10 minutes
of engine running time.
After your vehicle’s engine has been started
two times using the remote vehicle start button,
the vehicle’s ignition switch must be turned to RUN
and then back to LOCK using the key before
the remote start procedure can be used again.
SeeIgnition Positions on page 112for information
regarding the ignition positions on your vehicle.
You can start your vehicle’s engine from about
197 feet (60 m) away. However, the range may be
less while the vehicle is running, and as a result
you may need to be closer to your vehicle to turn it
off than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 91for
additional information.
/(Remote Start):If your vehicle has the remote
start feature, the RKE transmitter will have a
button with this symbol on it.

Climate Controls
Climate Control System
With this system you can control the heating,
cooling, and ventilation for the vehicle.
Operation
To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs about half of
the air to the instrument panel outlets, and
then directs the remaining air to the oor outlets.
Cooler air is directed to the upper outlets and
warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed to the
windshield and side windows.
The left knob can also be used to select defog or
defrost mode. Information on defogging and
defrosting can be found later in this section.
9(Fan):Turn the center knob clockwise or
counterclockwise to increase or decrease the
fan speed. In any setting other than off, the fan
will run continuously with the ignition on. The fan
must be turned on to run the air conditioning
compressor.
9(Off):To turn the fan off, turn the knob all the
way counterclockwise to the off position.
Temperature Control:Turn the right knob
clockwise or counterclockwise to increase or
decrease the temperature inside the vehicle.

h(Recirculate):Press this button to prevent
outside air and odors from entering the vehicle or
to help heat or cool the air inside the vehicle more
quickly. An indicator light above the button will
come on in this mode. The air conditioning
compressor also comes on. This mode is not
available for oor, defog and defrost modes. When
the recirculation button is pressed, the recirculate
indicator light will ash ve times and outside air will
be delivered. Operation in this mode during periods
of high humidity and cool outside temperatures may
result in increased window fogging. If window
fogging is experienced, select the defrost mode.
Outside Air:This mode allows outside air to
circulate through the vehicle. This mode is
automatically active if recirculate is not
selected. There is no button for outside air.
#(Air Conditioning):If your vehicle has
air conditioning, press this button to turn the
air conditioning system on or off. When this button
is pressed, an indicator light above the button
will come on to let you know the air conditioning
is activated.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:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select air conditioning.
4. Select the coolest temperature.
5. Select the highest fan speed.
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 off the
recirculation by pressing the button again.
The air conditioning system removes moisture
from the air, so you may sometimes notice a
small amount of water dripping underneath your
vehicle while idling or after turning off the
engine. This is normal.
The air conditioning compressor cannot be
turned on when the fan is off.
159

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
clear fog or frost from the windshield and side
windows. 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. For best results, clear all
snow and ice from the windshield before defrosting.Turn the left knob to select the defog or
defrost mode.
-(Defog):This mode directs about half of
the air to the windshield and the side window
outlets and half to the oor outlets. When
you select this mode the system runs the air
conditioning compressor. To defog the windows
faster, turn the temperature control knob clockwise
to the warmest setting.
0(Defrost):This mode directs most of the
air to the windshield, with some air directed to
the side window outlets and the oor outlets.
When you select this mode the system runs
the air conditioning compressor. To defrost the
windows faster, turn the temperature control knob
clockwise to the warmest setting.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring.
Check with your dealer. The arrows on your
instrument panel will ash whenever you signal a
turn or lane change. Properly hooked up, the
trailer lamps will also ash, telling other drivers
you are about to turn, change lanes or stop.
When towing a trailer, the arrows on your
instrument panel will ash for turns even if the
bulbs on the trailer are burned out. Thus, you may
think drivers behind you are seeing your signal
when they are not. It is important to check
occasionally to be sure the trailer bulbs are
still working.
Driving on Grades
Notice:Do not tow on steep continuous
grades exceeding 6 miles (9.6 km). Extended,
higher than normal engine and transmission
temperatures may result and damage your
vehicle. Frequent stops are very important to
allow the engine and transmission to cool.Reduce speed and shift to a lower gearbefore
you start down a long or steep downgrade. If you
do not shift down, you might have to use your
brakes so much that they would get hot and
no longer work well.
Pay attention to the engine coolant gage. If the
indicator is in the red area, turn off the air
conditioning to reduce engine load. SeeEngine
Overheating on page 309.
When towing under severe conditions such as hot
ambient temperatures or steep grades, your
vehicle may experience more transaxle shifting.
A COOLING MODE ON message may also appear
in the DIC. This alerts the driver that the shifting
mode is in progress and is aiding engine cooling.
SeeDIC Warnings and Messages on page 184
for more information.
