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
Nagain.
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.

Black plate (4,1)Chevrolet Corvette Owner Manual - 2012
8-4 Climate Controls
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.
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
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

Black plate (5,1)Chevrolet Corvette Owner Manual - 2012
Climate Controls 8-5
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. 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.

10-32 Vehicle Care
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highesttemperature and to the highest
fan speed. Open the windows
as necessary.
3. If in a traffic jam, shift to N (Neutral) while stopped. If it is
safe to do so, pull off the road,
shift to P (Park) or N (Neutral)
and let the engine idle.
If the temperature overheat gauge
is no longer in the overheat zone or
an overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle
right away. If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see
“Overheated
Engine Protection Operating Mode”
next in this section.
Overheated Engine
Protection
Operating Mode
This emergency operating mode
lets the vehicle be driven to a
safe place, up to 80 km (50 mi),
in an emergency situation. If an
overheated engine condition exists
and the messages COOLANT
OVER TEMPERATURE and
REDUCED ENGINE POWER are
displayed, along with the check
engine light, an overheat protection
mode which alternates firing groups
of cylinders helps prevent engine
damage. In this mode, there is a
significant loss in power and engine
performance. Driving extended distances in the
overheat protection mode should be
avoided.
Notice:
After driving in the
overheated engine protection
operating mode, to avoid engine
damage, allow the engine to cool
before attempting any repair.
The engine oil will be severely
degraded. Repair the cause of
coolant loss, change the oil
and reset the oil life system.
