Dual-Zone Automatic Temperature Control
The Dual Zone Automatic Temperature Control (ATC)
System automatically maintains the interior comfort level
desired by the driver and front seat passenger. This is
accomplished by using two infrared sensors located in
the center of the instrument panel. The two infrared
sensors independently measure the surface temperature
of the driver and front seat passenger. Based on the
sensor input, the system automatically adjusts the air
temperature, the airflow volume, the airflow distribu-
tion, and amount of inside air recirculation to maintain
front seat occupant comfort, even under changing out-
side weather conditions.
To operate the system, press either theAUTO HIor
AUTO LObuttons. The system now automatically
regulates the heating and air conditioning system includ-
ing blower speed, outlet air temperature, and airflow
distribution through the various outlets within the in-
strument panel. Using theTEMPbuttons, adjust the

temperature you would like the system to maintain.
When the system is set to your comfort level, it is not
necessary to change the settings. You will experience the
greatest efficiency by allowing the system to function
automatically. The system will operate fully automati-
cally in eitherAUTO HIorAUTO LO. TheAUTO
LOsetting will limit the maximum fan speed and should
be used when more quiet operation is desired. Use the
AUTO HIsetting when the quickest cool-down or
warm-up performance is desired.
NOTE:
•It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode and fan speed to provide
comfort as quickly as possible.
•The temperature can be displayed in U.S. or Metric by
selecting the US/M customer programmable feature.Refer to the “Electronic Vehicle Information Center-
Customer Programmable Features” in Section 3 of this
manual.
To provide you with maximum comfort in the automatic
mode, during cold start-ups the blower fan will remain
off and “DELAY” will appear in the display until the
engine warms up. An estimate of the time remaining
until the “DELAY” is complete will appear periodically
in the display. However, the fan will engage immediately
if the defrost mode is selected or by pushing the blower
switch and manually adjusting the fan speed.
This feature may be disabled using the following proce-
dure:
•Press and hold the Heated Rear Window and Auto LO
buttons for 5 seconds.
•The “DELAY” symbol will flash to indicate that the
feature as been disabled.

Power Button
This button turns the entire system ON/OFF. When the
system is turned on it will return to the previous settings.
Dual/Single Zone Operation
WhenDUALis displayed in the ATC control unit, the
driver and passenger air outlet temperatures can be
individually adjusted from the two independentTEMP
buttons. When a front seat passenger is not present,
pressing theDUALbutton will match the passenger’s
temperature setting to the driver’s temperature setting.
This will help equalize air outlet temperatures across theleft and right side of the instrument panel. The outside
temperature will replace the passenger’s temperature
setting in the display. Pressing theDUALbutton a
second time or adjusting the passenger’sTEMPbutton
will return the system to dual independent temperature
operation.
Manual Operation
This system offers a full complement of manual override
features. The indicator light in both theAUTO HIor
AUTO LObuttons will turn off when the system is
being used in the manual mode. The fan speed, airflow
distribution, and outside air/recirculated air can be
manually adjusted.
NOTE:Each of these features operate independently
from each other. If any one feature is controlled manually,
the remaining features will continue to operate automati-
cally.

The front blower control can be set to any fixed
blower speed by pressing the rocker switch up or
down. This allows the front occupants to control the
volume of air circulated in the vehicle and cancel the auto
mode. The fan will now operate at a fixed speed until
additional speeds are selected or until either theAUTO
HIorAUTO LObuttons are pressed. The system will
continue to automatically adjust air temperature and
airflow distribution.
The operator can also select the direction of the air by
pressing the mode control rocker switch located to the
left of the A/C button and selecting one of the following
positions.Panel Mode
Air comes from the outlets in the instrument panel. Each of
these outlets can be individually adjusted to direct the flow
of air. Moving the knob up, down, left, or right will direct the
air accordingly. The thumbwheel next to each outlet can be
rotated to reduce or shut off the air flow from these outlets.
