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 A Typical Cold Weather  Example: 
Your vehicle has been parked outside ~ver~~ight in 
cold weather (below 32  OF/ 0" C) and you  have  set 
the  driver temperature  at 73  OF  (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. 
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 vpical Hot Weather  Example: 
Your vehicle has Seen parked outside  all day  in  hot 
weather  (above 
70 OF/ 2 1 O C) and you  have  set  the 
driver temperature at 
73 "F (23 O C) and  have  selected 
the  AUTO  mode. The system will  automatically  adjust 
the temperature  output  to maximum  cooling.  The  blower 
will start at a low speed momentarily  to push  the  hot 
air to the  floor of the  vehicle  and then 
go to a higher 
blower 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  fresh  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).

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.

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.

If  you get the overheat warning but  see  or  hear no 
steam,  the problem  may not be  too serious. Sometimes 
the  engine can get a little  too  hot when you: 
Climb a long hill  on a hot  day. 
Stop after high-speed  driving. 
0 Idle for long periods in traffic. 
If  you  get the overheat warning with no sign  of steam, 
try  this  for a minute or 
so: 
1. 
2. 
3. 
Turn off  your  air conditioner. 
Turn  on  your heater  to  full  hot at the highest  fan 
speed  and  open the window  as necessary. 
If  you’re  in a traffic  jam, shift to  NEUTRAL 
(N); 
otherwise, shift  to the  highest  gear  while 
driving 
-- AUTOMATIC  OVERDRIVE (@) or 
DRIVE  (D) for automatic transmissions.  If  you 
no longer  have the overheat  warning, you can 
drive.  Just  to be safe, drive slower  for  about 
10 minutes. 
If  the warning doesn’t come back  on, you can 
drive  normally. 
If  the warning continues,  pull over,  stop, and park  your 
vehicle  right  away. 
If  there’s still no sign  of steam,  you can  idle  the engine 
for  two  or  three  minutes while you’re  parked, to see  if 
the  warning stops. But then, if  you still  have  the 
warning, 
turn  ofthe  engine and get everyone  out of the 
vehicle 
until  it cools down. Also,  see “Overheated 
Engine Protection Operating Mode” listed  previously in 
this  section.
