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

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 - 2011
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.

Climate Controls 8-5
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. 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 5 minutes.
.The vehicle's speed is above
52 km/h (32 mph) for
2.5 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.

WARNING (Continued)
SeeOverheated Engine
Protection Operating Mode on
page 10‑35 for information on
driving to a safe place in an
emergency.
If No Steam is Coming from
the Engine
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day
.Stops after high-speed driving
.Idles for long periods in traffic If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature 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.
