CHEVROLET CORVETTE 2009 6.G Owners Manual

When the vehicle is rst started, the display shows the
driver’s temperature setting, the outside temperature,
the fan speed and the air delivery, for about 10 seconds.
The outside temperature is shown in the center of the
display. The digital display will show the readings
in Fahrenheit or Celsius. See “Personal Options”
underDIC Vehicle Personalization on page 3-71for
information on changing your display.
Automatic Operation
AUTO (Automatic):Press the AUTO button to place
the entire system in the automatic mode. When
automatic operation is active, the system automatically
controls the inside temperature, the air delivery
mode, and the fan speed.
After a ten second display of the current settings,
the word AUTO, the driver’s temperature setting
and the outside temperature will be shown.The system operates to reach the set temperature as
quickly as possible. The AUTO control system works
best with the windows up and the removable roof
installed or the convertible top up.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 60°F (16°C) and 90°F (32°C). Choosing
the coldest or warmest temperature setting will
not cause the system to heat or cool any faster.
A setting of 73°F (23°C) is suggested.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system starts
out blowing air at the oor but may change modes
automatically as the vehicle warms up to maintain
the chosen temperature setting. The length of
time needed for warm up depends on the outside
temperature and the length of time that has elapsed
since the vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensor” later in
this section.

speed. The fan speed setting will appear in the display.
Pressing the arrows will delete AUTO from the digital
display. The fan graphics with the fan speed bars will be
shown. The AUTO button must be pressed to return to
the automatic fan control.
If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-30and
Scheduled Maintenance on page 6-4.
N(Air Delivery Mode Control):Press this button to
manually lock in the current air delivery setting and
to stop the automatic mode control. Pressing

The AUTO button must be pressed to return to the
automatic mode selection.
To change the current mode, select one of the following:
H(Vent):Air is directed to the instrument panel
outlets, with some air directed to the oor outlets.
%(Bi-Level):Air is divided between the instrument
panel and oor outlets.
6(Floor):Air is directed to the oor outlets, with
some air directed to the windshield and side window
defogger outlets.
-(Floor/Defog):This mode clears the windows of fog
or moisture. Air is directed to the windshield and the
oor outlets, with a small amount to the side window
outlets. In this mode, the system automatically turns
off the recirculation and runs the air-conditioning
compressor unless the outside temperature is at or
below freezing. The recirculation mode cannot be
selected while in the defog mode.
3-26

1(Defrost):This mode clears the windows of fog or
frost more quickly. Air is directed to the windshield,
with a small amount directed to the side window outlets.
The indicator light comes on and the digital display
will show the defrost mode symbol and fan speed when
the front defrost mode is being used. In this mode,
the system automatically turns off the recirculation and
runs the air-conditioning compressor, unless the
outside temperature is at or below freezing.
Recirculation cannot be selected while in the defrost
mode. Pressing
1again will return the system to the
last operating mode.
For severe ice conditions, turn the driver’s temperature
knob to 90°F (32°C) while in defrost mode.
Do not drive the vehicle until all the windows are clear.
^(Air Conditioning Off):Press to turn the air
conditioning compressor off. Press AUTO to return to
automatic operation. When in AUTO, the air conditioning
compressor comes on automatically, as needed.
Air conditioning does not operate at temperatures below
about 35°F to 40°F (2°C to 4°C). In temperatures
above 40°F (4°C), the air conditioning cannot be turned
off in defrost and defog, as it helps to remove moisture
from the vehicle. It also helps to keep the windows clear.You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
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 press the AUTO button
and adjust the temperature to a cool, comfortable setting.
To achieve maximum cool down, do the following:
1. Select
Hmode.
2. Press
?.
3. Select the a/c on.
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 your vehicle to become
too dry. To prevent this from happening, after the
air in the vehicle has cooled, turn the recirculation
mode off.
3-27

The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine.
This is normal.
?(Recirculation):Press to turn the recirculation
mode on or off. An indicator light comes on to show that
recirculation is on. This mode prevents outside air
from entering your vehicle. It can be used to prevent
outside air and odors from entering your vehicle and to
help cool the air inside your vehicle more quickly.
Recirculation mode is not available in defrost or
defog mode.
Sensors
The solar sensor on the vehicle monitors the solar heat
and uses the information to maintain the selected
temperature when operating in AUTO mode by
automatically adjusting the temperature, fan speed and
air delivery system. The system may also supply
cooler air to the side of the vehicle facing the sun.
The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located on the
top of the instrument panel near the windshield or the
system will not work properly.There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps to maintain the temperature inside the vehicle.
Any cover on the front of the vehicle could give a false
reading in the temperature.
If the outside temperature goes up, the displayed
temperature will not change until:
The vehicle’s speed is above 12 mph (19 km/h) for
ve minutes.
The vehicle’s speed is above 32 mph (52 km/h) for
two and a half minutes.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
There is also an inside temperature sensor located to
the left of the ignition switch. The automatic climate
control system uses this sensor to receive information,
so if you block or cover it, the system will not function
properly.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger only works when the
engine is running.
=(Rear Window Defogger):Press to turn the
rear window defogger on or off. Be sure to clear as
much snow from the rear window as possible.
An indicator light comes on to show that the rear
window defogger is on.
The rear window defogger turns off about 10 minutes
after the button is pressed when traveling less than
30 mph (48 km/h). If turned on again, the defogger only
runs for about ve minutes before turning off. The
defogger can also be turned off by turning off the engine.
The vehicle has heated outside rearview mirrors.
The mirrors will heat to help clear fog or frost from the
surface of the mirrors when the rear window defogger
button is pressed.
For vehicles with a power convertible top, the rear
window defogger and heated mirrors are automatically
disabled when the power convertible top is moving
or down.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.Outlet Adjustment
Use the tab located on the air outlets to change the
direction of the airow.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of
your vehicle more effectively.

Passenger Compartment Air Filter
The passenger compartment air lter removes certain
particles from the air including pollen and dust particles.
Reductions in airow, which may occur more often in
dusty areas, indicate that the lter may need to be
replaced. SeeScheduled Maintenance on page 6-4
for information on how often to replace the lter.
Notice:Driving without a passenger compartment
air lter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the
old lter with a new one.
The passenger compartment air lter is located on the
passenger side of the engine compartment near the
battery. SeeEngine Compartment Overview on
page 5-14.To check or replace the air lter:
1. Remove the cover retainer clips (A) from the
passenger compartment air lter cover.
2. Remove the cover.
3-30

3. Remove the lter and install the new air lter.
4. Replace the lter cover.
5. Attach the retainer clips.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is started
to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.

Speedometer and Odometer
The speedometer shows the speed in either miles per
hour (mph) or kilometers per hour (km/h). For more
information see “Personal Options” underDIC Vehicle
Personalization on page 3-71.
To read the odometer with the ignition off, turn on the
parking lamps.
If the vehicle needs a new odometer installed, the
mileage total of the new odometer will be set to the
original miles (kilometers) of the old odometer. See your
dealer/retailer if the odometer must be replaced in the
vehicle.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Notice:Fuel shuts off at about 6500 rpm for the
base model, 7000 rpm for the Z06 model, and
6600 rpm for the ZR1 model. If the vehicle continues
to be driven at the fuel shut off rpm, the engine
could be damaged. Be sure to operate the vehicle
below the fuel shut off rpm or reduce the vehicle’s
rpm quickly when the fuel shuts off.
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime comes on for
several seconds to remind people to fasten their safety
belts, unless the driver safety belt is already buckled.
The safety belt light also
comes on and stay on for
several seconds, then
it ashes for several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s
safety belt is already buckled, neither the chime nor the
light comes on.
