When the vehicle is first 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”underVehicle
Personalization on page 5‑55 for
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 10 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
16°C (60°F) and 32°C (90°F).
Choosing the coldest or warmest
temperature setting will not
cause the system to heat or cool
any faster. A setting of 23°C
(73°F) 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 floor 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 “Sensors”later
in this section.
Manual Operation
Driver Power/Temperature: Press
the driver temperature knob to turn
the climate control system off. This
is the only setting that completely
shuts off the fan. The digital display
shows only the outside temperature.
The driver and the passenger set
temperature and the air intake mode
can still be adjusted when the
climate control is off.
Passenger Power/Temperature:
Press the passenger temperature
knob to turn the passenger's climate
control system on or off. Turn the
knob to increase or decrease the
temperature for the passenger.

If the passenger's climate control
system is off, the driver's
temperature knob will control the
temperature for the entire vehicle.
x 9 w(Fan):Press to increase
or decrease the fan 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 airflow seems low when the
fan speed is at the highest setting,
the passenger compartment air filter
may need to be replaced. For more
information, see Passenger
Compartment Air Filter on page 8‑6.
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
Ndeletes AUTO from
the digital display and the mode
graphics will be shown. To change the setting, press
N
again. 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 floor outlets.
%(Bi-Level): Air is divided
between the instrument panel and
floor outlets.
6(Floor): Air is directed to the
floor 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
floor 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.
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 32°C
(90°F) while in defrost mode.

8-4 Climate Controls
^(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 2°C to
4°C (35°F to 40°F). In temperatures
above 4°C (40°F), 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.
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.

Black plate (5,1)Chevrolet Corvette Owner Manual - 2012
Climate Controls 8-5
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
19 km/h (12 mph) for
five minutes.
.The vehicle's speed is above
52 km/h (32 mph) for two and
one‐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 48 km/h (30 mph). If turned on
again, the defogger only runs for
about five 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.

9-12 Driving and Operating
Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
Carbon Monoxide (CO) which
cannot be seen or smelled.
It can cause unconsciousness
and even death.
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
(Continued)
WARNING (Continued)
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control System in
the Index.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑26.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (Carbon
Monoxide) gas to get inside.
CO could overcome you and
kill you. You cannot see it or
smell it, so you might not know
it is in your vehicle.

Driving and Operating 9-13
WARNING (Continued)
Clear away snow from around the
base of your vehicle, especially
any that is blocking the exhaust.
Run the engine for short periods
only as needed to keep warm,
but be careful.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart the vehicle and to signal for
help with the headlamps. Do this as
little as possible to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 55 km/h (35 mph).
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑80.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a forward
gear, or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out,
see Towing the Vehicle on
page 10‑86.

the Driver Information Center (DIC).
For more information, see
Transmission Messages on
page 5‑53.
When the engine is off, press this
button to place the vehicle in
accessory mode. ACCESSORY
MODE ON will display on the Driver
Information Center (DIC). This mode
allows you to use things like the
radio and the power windows while
the engine is off. Use accessory
mode if you must have the vehicle in motion while the engine is off, for
example, if the vehicle is being
pushed or towed.
After being in accessory mode for
about 10 minutes, the vehicle will
automatically enter RAP or OFF,
depending on if the doors are
opened or closed.
Service Only Mode
This power mode is available for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. With the vehicle off,
pressing and holding the bottom of
the button for more than
five seconds will place the vehicle in
