Downloaded from www.Manualslib.com manuals search engine Automatic Electronic Dual Climate Control System (Option)
Your Corvette may be equipped with a Dual Zone
Electronic 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 control settings will be remembered each
time you turn the ignition
off and restart in the same
settings.
You can use the Memory option to store and
recall your settings. (See “Memory” in the Index.)
Digital Display
The digital display shows readings in Fahrenheit or
Celsius by pressing the
EM button (EnglishlMetric) 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.
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.

Downloaded from www.Manualslib.com manuals search engine 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:
0 The vehicle’s speed is above 20 mph (32 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 your 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 just 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, your vehicle will cool down more
quickly and economically if you open the windows
long enough to let hot inside air escape. Then keep your
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 your 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 your vehicle when
it is idling or after it has been turned
off. This is normal.
