If you want continuous maximum cooling, push the
BLUE button until60ÊF(16ÊC) isshown in the
display window. Your EATC will cool at maximum
and disregard the60ÊF(16ÊC)setting until you
select a warmer temperature with the RED button.
If you want continuous maximum heating, push the
RED button until90ÊF(32ÊC) isshown in the
display window. Your EATC will provide maximum
heat regardless of the90ÊF(32ÊC)setting until you
select a cooler temperature with the BLUE button.
The display window tells you how the system is
operating. It will indicate the selected temperature
and the operating function you have chosen; AUTO
or one of the six manual overrides. It will also
indicate manual (thumbwheel) control of the fan
speed with the
Hsymbol. The display window
with all possible displays and their positions are
shown here. Normally not all are shown at the
same time but are included here to familiarize you
with the names and symbols.
Automatic operationPush the AUTOMATIC button and select the
desired temperature. The selected temperature and
AUTO will be shown in the display window. The
EATC will automatically heat or cool to achieve the
set temperature. Under normal conditions, your
EATC will need no additional attention.

58When in AUTOMATIC and weather conditions
require heat, air will be sent to the floor. But, a
feature is included in your EATC to prevent
blowing cold air to the floor if the engine coolant is
not warm enough to allow heating. For a short
time the fan will be at low speed and air directed
to the windshield. In 3-1/2 minutes or less, the fan
speed will start to increase and the airflow will
change to the floor area.
If unusual conditions exist (i.e., window fogging,
etc.), the six manual override buttons allow you to
select special air discharge locations. A thumbwheel
allows you to adjust the fan speed to suit your
needs.
Temperature selectionThe RED and BLUE buttons at the upper left of the
Control are for temperature selection. The RED
button will increase the set temperature and the
BLUE button will lower the set temperature.
Pressing a button and releasing it will change the
set temperature one degree. Holding either button
in will rapidly change the temperature setting in
one degree increments to either65ÊF(18ÊC)
(BLUE) or85ÊF(29ÊC)(RED).Then, the set
temperature will jump 5 Ê and stop at either60ÊF
(16ÊC)which is maximum cooling or90ÊF(32ÊC)
which is maximum heating.
The average temperature range used is between
68ÊF(20ÊC) and78ÊF(26ÊC).Changing the
temperature setting by several degrees outside this
range or overriding to60ÊF(16ÊC) or90ÊF(32ÊC)
will not speed up the heating or cooling process.

Temperature displayThe selected temperature displayed in the window
can be set for either Ê F or Ê C . Your car may have
an English/Metric (E/M) Button to change your
speedometer from miles to kilometers. When
pressed, this button also changes the temperature
display. With or without an E/M Button, the
temperature display can also be changed to Ê F or
Ê C using the MAX A/C and DEFrost override
buttons.

To change the temperature display to Ê F or Ê C ,
press and hold the MAX A/C and DEF Buttons at
the same time for 3/4 second. The display will
change. If you continue to press the two buttons,
the display will continuously switch between Ê F and
Ê C . If the temperature display does not agree with
the speedometer on vehicles with an E/M button,
pressing the E/M button will make them agree.Fan speed and thumbwheelYour EATC automatically adjusts the fan speed to
the existing conditions. You must push
AUTOMATIC for automatic fan speed operation. To
control the fan speed yourself, use the thumbwheel
which will cancel the automatic fan speed control.
The thumbwheel is located at the extreme right
side of the EATC control panel. It is a vertical
control marked with a fan symbol. Rotate up for HI
and down for LO speeds.

When you move the thumbwheel, the fan speed
will go to manual control. The display window will
show the
Hsymbol in the upper left corner along
with the selected temperature and operating
function.
You can override the fan speed at any time. If you
use the thumbwheel to override the fan speed, the
EATC will continue to control the temperature but
you control the fan speed. To return to auto fan
control, press the AUTOMATIC button. If you are
operating in one of the override functions (FLOOR,

62MAX A/C, etc.), automatic fan control will
continue unless you rotate the fan thumbwheel. To
return to automatic fan control, press the
AUTOMATIC button. The EATC will return to
Automatic operation. If you want to return to any
override function, press the button for that function.
The fan speed will continue to be automatically
controlled.Steering wheel remote control buttonsSome cars have control buttons to the right side of
the center of the steering wheel which allow you to
control some radio and climate control features.
Refer to theSteering Column Controlschapter later
in this owner guide for further information.Manual override buttonsYour EATC has six buttons which allow you to
make special selections. The buttons are located
along the bottom edge of the EATC control and
allow you to determine where the air will be
discharged. Pressing any override button changesthe air discharge location only. It does not affect
the ability of the system to control temperature or
the fan speed. Return to fully Automatic operation
by pushing the AUTOMATIC button.
MAX A/C button
The MAX A/C feature allows for faster cooling
because air is drawn from inside the vehicle. Using
inside air causes the fan to sound louder which is
normal for this selection. The Display window will
change to indicate60ÊF(16ÊC) and MAXA/C. The
fan will run and the airflow will be from the
instrument panel registers. To exit and return to the
previous temperature, push AUTOMATIC or any of
the other five override buttons.
NORM A/C button
When you push this button, you select air
conditioning using outside air. The Display window
will indicate A/C under the selected temperature.
The cooled air will flow from the instrument panel
registers. The fan speed will continue on automatic.

VENT button
Push this button to select outside air through the
instrument panel registers. The display window will
show the set temperature and VENT to the lower
right of the temperature. Your EATC will heat the
air if the temperature you have selected is warmer
than the outside air coming into the vehicle.
However, the air will NOT be cooled regardless of
the temperature setting.
FLOOR button
Airflow will be to the floor when the FLOOR
button is pressed. The display window will show
the set temperature and FLR to the left of the
temperature. The air cannot be cooled in the FLR
position, only heated. Fan speed will be automatic
unless manually controlled. If you override the fan
speed and wish to return to automatic fan control,
push AUTOMATIC. Then, again select FLOOR for
airflow to the floor.FLR & DEF button
Push this button to get air to the floor and
windshield defrosters at the same time. The display
will show the set temperature, FLR and the Defrost
symbol. If the outside temperature is about50ÊF
(10ÊC) andabove, the air will be dehumidified to
remove moisture. This will help to prevent fogging
in humid weather.
DEF button
Press the Defrost Button to obtain maximum airflow
to the windshield. Adjust the temperature setting as
required for defrosting. The Display window will
show the temperature setting with the Defrost
symbol to the left of the temperature. When the
outside temperature is about50ÊF(10ÊC) and
above, the air will be dehumidified to remove
moisture. This will help prevent fogging in humid
weather.

64OUTSIDE TEMP button
By pressing this button the temperature of the air
outside of the vehicle will show in the display. The
outside temperature will continue to be displayed
until the OUTSIDE TEMP button is pressed again
to cancel. If the selected temperature setting is
changed while the outside temperature is displayed,
the new selected temperature will be displayed for
4 seconds after it is changed. Then, the outside
temperature will return to the window. If a manual
override is pressed or the thumbwheel is rotated
while the outside temperature is displayed, the
window will show the change for 4 seconds. Then,
the outside temperature will return along with the
changed override selection.
If the EATC is turned OFF while the outside
temperature is displayed, the temperature will
continue to be displayed. Press the OUTSIDE TEMP
button to clear the display window. When the
ignition key is turned OFF the display will be blank
(dark).

NOTE:The outside temperature reading is most
accurate when the vehicle is moving. Higher
readings may be obtained when the vehicle is not
moving. The readings that you get may not agree
with temperatures given on the radio due to
differences in vehicle and station locations.Operating tipsThe following tips will help you to get the most
satisfaction from your Electronic Automatic
Temperature Control system.q
In humid weather, select DEFVbefore
starting your engine. This will help to prevent
windshield fogging. After a few minutes of
operation, switch to AUTOMATIC or an
override selection of your choice.
q
To prevent humidity buildup inside your
vehicle, always drive with the EATC System
turned on.
q
Do not put objects under the front seats that
interfere with the flow of air to the back seat
area.
q
Remove any snow, ice, or leaves from the air
intake area of your EATC System which could
block the air intake. The intake area is located
at the bottom of the windshield, under the
hood at the passenger side rear corner.
ServiceIf your EATC is not operating as described here,
take it to your dealer to have it checked. System
diagnostics are built in which will allow your dealer
to readily identify problems that might occur.
