2001 CHEVROLET CORVETTE air condition

3-4 Automatic Electronic Dual Climate
Control System (Option)
Your vehicle may be equipped with an Automatic
Electronic Dual Climate Control System. This system
can automatically adjust and control temperature output,
fan speed, air delivery mode, air conditioning operation
and air intake. You can use the AUTO (automatic)
setting or override the automatic operation with manual
control settings. The set temperature will be
remembered each time you turn the ignition off and
restart in the same settings. You can use the memory
option to recall your settings. See ªMemoryº in
the Index.Digital Display
The digital display shows readings in Fahrenheit or
Celsius by pressing the E/M button (English/Metric) on
the Driver Information Center (DIC). When you start
the vehicle, the display will show the current fan speed,
air delivery mode and the driver
-set temperature
for approximately five seconds and then show the
outside temperature.
When the system is fully in the automatic mode, the
word AUTO will also appear on the display unless you
are in full cold 60
F (16
C) or full hot 90
F (32
C),
then the word AUTO will not display. If you have
selected a manual fan speed, then the fan symbol will
appear on the display. If a manual air delivery mode has
been selected, the delivery mode symbol will appear on
the display.
Driver Set Temperature Knob
The DRIVER knob changes the temperature on the
driver's and passenger's side of the vehicle. Turn the
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature.
Whenever you turn this knob, the temperature will be
displayed for approximately five seconds along with the
current fan speed and air delivery mode.

3-5
When adjusting the temperature, start with a driver-set
temperature of 73
F (23
C) until you determine
your comfort zone. If you choose 60
F (16
C), the
system will remain at maximum cooling and will not
automatically adjust fan speed or air delivery. If you
choose 90
F (32
C), the system will remain at
maximum heating and will not automatically adjust fan
speed or air delivery. Choosing either maximum setting
will not cause the system to heat or cool any faster.
Turning the knob past either maximum setting has no
effect on the operation of the system.
Passenger Temperature Offset
The PASSENGER knob changes the temperature on the
passenger's side of the vehicle. When the knob is in the
12 o'clock position, the passenger's temperature is the
same as the driver's. Turn the knob clockwise for warmer
air on the passenger's side, counterclockwise for cooler air.
If the driver
-set temperature is set at 60
F (16
C) or
90
F (32
C), turning the passenger knob has no effect
because the system is locked at a maximum setting.Automatic Operation
Press the AUTO button to place the entire system in the
automatic mode. After a five
-second display of the
current settings, only the word AUTO and the outside
temperature will be shown on the digital display unless
you are in full cold 60
F (16
C) or full hot 90
F
(32
C), then the word AUTO will not display. The
system will operate to achieve your comfort 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.
A Typical Cold Weather Example:
Your vehicle has been parked outside overnight in cold
weather below 32
F (0
C) and you have set the
driver temperature at 73
F (23
C) and have selected
the AUTO mode. The system will automatically adjust
the temperature output to maximum heating. The fan
will start at a low speed. This is to avoid blowing cold
air into the vehicle. The length of the delay depends on
the amount of time since the engine was last started, the
outside temperature and the engine coolant temperature.
As the coolant warms up, the fan speed will gradually
increase. Air will flow to the floor with some air to
the windshield to prevent fogging under most
normal conditions.

3-6
As the interior of the vehicle warms up to your comfort
set temperature, the fan speed will decrease and the
temperature output may become cooler. If the interior
temperature continues to warm up due to heating from
the sun or outside temperature increases, the system
may switch to other air delivery modes (typically
DEFOG or BI
-LEVEL).
A Typical Hot Weather Example:
The vehicle has been parked outside all day in hot
weather above 80
F (27
C) and you have set the driver
temperature at 73
F (23
C) and have selected the
AUTO mode. The system will automatically adjust the
temperature output to maximum cooling. The fan will
start at a low speed momentarily to push the hot air to
the floor of the vehicle and then go to a higher fan speed
with cold airflow out of the instrument panel outlets. A
small amount of airflow will continue through the lower
ducts to cool the floor area.The air intake may start in the recirculated mode for
maximum cooling performance. As the interior of the
vehicle cools down to your comfort set temperature,
the fan speed will decrease and the temperature output
may become warmer. The air intake may shift from
recirculation to outside air mode. If the interior
continues to cool due to a decrease in the amount of heat
the vehicle is absorbing from the sun or a decrease in the
outside temperature, the system could switch to other air
delivery modes (typically BI
-LEVEL or DEFOG).
Manual Settings
With the automatic electronic dual climate control
system, there are several manual settings you can use to
control the system and override the AUTO operation.
You can program the fan speed, air delivery mode, air
intake mode and control the air conditioning operation
using these settings. The system will still determine the
temperature output level based on the driver
-set
temperature and the passenger temperature offset.

3-7
FAN SPEED: Press the button with the fan symbol
on it to manually lock in the current fan speed and to
stop the automatic fan speed control. Pressing the
arrows will delete AUTO from the digital display. The
fan graphics with the fan speed bars will be shown. To
increase the fan speed so that more air flows into the
vehicle, press the UP arrow on the fan switch. To
decrease the fan speed and airflow, press the DOWN
arrow. The AUTO button must be pressed to return to
the automatic fan control.
MODE: Press the MODE button to manually lock in the
current air delivery setting and to stop the automatic
mode control. Pressing the MODE button will delete
AUTO from the digital display and the mode graphics
will be shown. To change the setting, press the MODE
button again. The AUTO button must be pressed to
return to the automatic mode selection.
UPPER: This setting directs most of the air
through the instrument panel outlets and a very small
amount to the lower outlets.
BI-LEVEL: This setting directs air into the
vehicle in two ways. Cooler air is directed toward your
upper body through the instrument panel outlets, while
warmer air is directed through the lower outlets.
LOWER: This setting directs most of the air to
the floor area and some of it toward the windshield and
side window vents.
DEFOG: This setting divides the air between
the windshield and lower outlets and a small amount
toward the side window vents. This is useful when fog
appears on the windshield or side glass due to rain or
snowy conditions.
Function Buttons
These buttons control climate control ON/OFF, air
intake, front defrost, rear defrost and the air
conditioning operation.
OFF: Press the OFF button to turn off the climate
control system. This is the only setting that fully shuts
off the fan. The digital display will show only the
outside temperature. You can still adjust the driver set
temperature, the passenger temperature offset and the
air intake mode while in OFF.

3-8
A/C: This button turns the air conditioning
compressor off or on under most conditions. The light
on the A/C button will come on when the compressor is
operating in either the automatic or manual mode. The
air conditioning does not operate at temperatures below
approximately 35
F to 40
F (2
C to 4
C). The light
on the A/C button will flash if pressed when air
conditioning is not available. The air conditioning cools
and dehumidifies the air coming into the vehicle. 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.
If the system is operating in the AUTO mode, turning
the air conditioning off will delete AUTO from the
digital display and show current mode and fan settings.
The AUTO button must be pressed to return to the
automatic mode operation.
The air conditioning may be forced off at high engine
speeds or high engine oil or coolant temperatures. OUTSIDE AIR: Press this button to provide
outside air. The light on this air intake button will come
on to show when it is operating. When in the AUTO
mode, the system automatically selects OUTSIDE AIR
instead of recirculate, as required, to control the
temperature in the vehicle. By pressing OUTSIDE AIR,
the system will lock into the outside air mode. Any
adjustment to the air intake must then be made
manually. OUTSIDE AIR should be used when trying to
defrost or defog windows to help reduce moisture inside
of the vehicle.
RECIRCULATE: Press this button to limit the
amount of outside air entering the vehicle. The light on
this air intake button will come on to show when it is
operating. Recirculate is helpful when you are trying to
cool the air quickly or trying to limit odors and dust
from entering the vehicle. When in the AUTO mode,
the system automatically selects recirculate to cool the
vehicle's temperature. By pressing this button, the
system will lock into the recirculated air mode.
Any adjustment to the air intake must then be made
manually. Recirculation is not available when using the
defrost or defog mode because outside air is need to
reduce moisture inside of the vehicle.

3-10
Outside Air Temperature Sensor
This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor
is used for the outside air temperature readings
shown on the digital display for the automatic climate
control system.
If the outside temperature goes up, the displayed
temperature will not change until:

The vehicle's speed is above 16 mph (26 km/h) for
one and a half minutes.

The vehicle's speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature display
is updated immediately.
If the vehicle has been turned off for more than three
hours, the current 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.Inside Temperature Sensor
This sensor is 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.
Air Conditioning
On very hot days, the vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot inside air escape. Then keep the
windows closed in order to allow the air conditioning to
work best. Maximum cooling will occur when the
recirculate setting is operating, airflow direction is in the
upper mode, and the temperature knob (on a manual
climate control system) is turned all the way to the blue
area. These settings will be selected by the automatic
electronic dual climate control system if operating in
AUTO when maximum cooling is required.
When the air conditioning is on, you may
sometimes notice slight changes in the vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while maintaining the
desired cooling level.
The air conditioning removes moisture from the air,
so you may notice water dripping from under the
vehicle when it is idling or after it has been turned off.
This is normal.

the changer and the radio is turned on, to play a compact
disc. Press AM
-FM to return to the radio when a
compact disc is playing. Press CD AUX to switch
between the trunk
-mounted CD changer and compact
disc if both are loaded.To eject the disc holder in the trunk
-mounted CD
changer, slide the CD changer door all the way open and
the disc holder will automatically eject.
Compact Disc Changer Errors
If an error occurs while trying to play a CD in the
compact disc changer, the following conditions may
have caused the error:

The road is too rough. The disc should play when the
road is smoother.

The disc is dirty, scratched, wet or loaded label
side up.

The air is very humid. (If so, wait about an hour
and try again.)

The CD changer door is open. Completely close the
changer door to restore normal operation.

An empty magazine is inserted in the CD changer.
Try the magazine again with a disc loaded on one of
the trays.
If any error occurs repeatedly or if an error cannot be
corrected, please contact your dealer.

4-17
If your TCS system is off, then an acceleration skid
is also best handled by easing your foot off the
accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to go. If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you'll
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting to a lower
gear). Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until your
vehicle is skidding. Learn to recognize warning
clues
-- such as enough water, ice or packed snow on
the road to make a ªmirrored surfaceº
-- and slow
down when you have any doubt.
Remember: Any anti
-lock brake system (ABS) helps
avoid only the braking skid.
Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired
-- by alcohol or drugs, with night vision
problems, or by fatigue.
