2002 CHEVROLET CORVETTE Owners Manual

3-9
(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 needed to
reduce moisture inside of the vehicle.
Operating the system in the recirculation mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
system to either the defog or defrost mode and increase
the fan speed. To avoid re
-fogging of the windows,
operate the system in the outside air mode.
FRONT: Press the FRONT defrost button to
quickly remove fog or frost from the windshield.
This setting directs most of the airflow to the windshield
and a small amount toward the lower and side window
outlets. The light on the button will come on and the
digital display will show the defrost mode symbol and
fan speed when the front defrost mode is being used.
Pressing FRONT defrost again will return the system to
the last operating mode and the air intake mode will be
in outside air.
If the system is in front defrost when you shut the
engine off, it will restart in FRONT defrost unless the
engine is off for longer than 40 minutes. If the engine is
off longer than 40 minutes, the system will restart in the
operating mode you had set prior to FRONT defrost and
the air intake mode will be in outside air.
See ªRear Window Defoggerº later in this section for
more information.

3-10 Sensors
The automatic electronic dual climate control system
uses several sensors to control operation and
display information.
Solar Load Sensor
This sensor is located on the top right side of the
defroster grille. The defroster grille is on the top of
the instrument panel.
The sensor monitors the sun's solar radiation and uses
this information as part of the automatic climate control
system when operating in the AUTO mode.
Be careful not to put anything over the sensor. When
covered, the sensor cannot compensate for changes in
the amount of heat the vehicle is absorbing from the sun.
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.

3-11 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 control 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.
Heating
The heater works best if you keep the windows closed.
Maximum heating will occur when airflow direction is
in the lower mode and the temperature control knob
(on a manual climate control system) is all the way in
the red area. These settings will be selected by the
automatic electronic dual climate control system if
operating in AUTO when maximum heating is required.
The bi
-level setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
The bi
-level setting will direct cooler airflow to your
upper body and warmer air to the floor area.
If you have the optional engine coolant heater and use it
during cold weather 0
F (
-18
C) or lower, the heating
system will provide heat more quickly because the
coolant is already warmed. See ªEngine Coolant Heaterº
in the Index.

3-12 Defogging and Defrosting
To rapidly defrost the windshield, the FRONT defrost
mode (automatic electronic dual climate control system)
or defrost mode (manual control system) should be used
and the fan speed should be adjusted to the highest
speed. With the manual control system, turn the
temperature control knob all the way to the red area.
To keep the windshield clear and provide heated air to
the floor area of the vehicle, use the defog setting.
Your vehicle is equipped with side window defogger
vents located near the side rearview mirrors.
Rear Window Defogger
REAR: This button turns the rear defogger and the
heated outside mirrors on. The light on the button will
come on when operating. The system automatically
shuts off after approximately 15 minutes. If further
defogging is desired, press the button again and it will
operate for about seven and a half more minutes.
The rear window defogger operates only when the
engine is running.
The rear window defogger uses a warming grid to
remove fog from the rear window. Do not attach
anything like a temporary vehicle license or a decal
across the defogger grid on the rear window.
NOTICE:
Don't use a razor blade or something sharp on
the inside of the rear window. If you do, you
could cut or damage the warming grid, and
repairs wouldn't be covered by your warranty.

3-13 Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the fan is running.
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.

When you enter a vehicle in cold weather, turn the
fan to the highest speed for a few moments before
driving off. This helps clear the intake outlets of
snow and moisture, and reduces the chance of
fogging the inside of the windows.

Keep the area around the base of the center
instrument panel console and air path under the seats
clear of objects. This helps air circulate throughout
the vehicle.
Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off. See
ªRetained Accessory Powerº in the Index.
Setting the Clock
Press and hold HR until the correct hour appears.
Press and hold MN until the correct minute appears.

SCV (Speed
-Compensated Volume): With SCV,
your audio system adjusts automatically to make up for
road and wind noise as you drive. Set the volume at the
desired level. Turn the control ring behind the upper
knob clockwise to adjust the SCV. Each notch on the
control ring allows for more volume compensation
at faster vehicle speeds. Then, as you drive, SCV
automatically increases the volume, as necessary, to
overcome noise at any speed. The volume level should
always sound the same to you as you drive. If you don't
want to use SCV, turn the control all the way down.
