Automatic Operation
1. Press the AUTO button on the Front Upper ATC Panel
and the word AUTO will illuminate in the front ATC
display, along with three temperatures for driver, front
passenger, and rear seats. The system will then automati-
cally regulate the amount of airflow.
2. Next, adjust the temperature you would like the
system to maintain, by adjusting the driver, front passen-
ger, and rear seat rotary temperature knobs. Once the
desired temperature is displayed, the system will achieve
and automatically maintain that comfort level.
3. When the system is set up for your comfort level, it is
not necessary to change the settings. You will experience
the greatest efficiency by simply allowing the system to
function automatically.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 English or Metric
units by selecting the “Display Units of Measure in”
customer-programmable feature. Refer to the “Elec-
tronic Vehicle Information Center (EVIC) — Customer-
Programmable Features” in this Section.
To provide you with maximum comfort in the automatic
mode, during cold start-ups, the blower fan will remain
on low and the DELAY symbol will appear in the front
ATC display, until the engine warms up. The fan will
engage immediately if the DEFROST mode is selected, or
by pressing the Front Upper ATC Panel blower rocker
button and setting the fan to any fixed blower speed.

from each other. If any one feature is controlled manually,
the temperature doors will continue to operate automati-
cally.
The blower fan speed can be set to any fixed speed by
pressing the Front Upper ATC Panel blower rocker
button. The fan will now operate at a fixed speed until
additional speeds are selected. This allows the front
occupants to control the volume of air circulated in the
vehicle and cancel the AUTO mode.
The operator can also select the direction of the airflow
by selecting one of the following positions. Panel Mode
Air is directed through the outlets in the instrument
panel. These outlets can be adjusted for direction,
and turned on or off to control airflow.
NOTE: For maximum airflow to the rear, the center
instrument panel outlets can be directed toward the rear
seat passengers.
Bi-Level Mode Air comes from the instrument panel outlets, floor
outlets and defrost outlets. A slight amount of air is
also directed through the side window demister outlets.
NOTE: In many temperature positions, the BI-LEVEL
mode is designed to provide cooler air out of the panel
outlets and warmer air from the floor outlets.

Floor ModeAir comes from the floor outlets. A slight amount of
air is directed through the defrost and side window
demister outlets.
Mix Mode Air comes from the floor, defrost and side window
demist outlets. This mode works best in cold or
snowy conditions. It allows you to stay comfort-
able, while keeping the windshield clear.
Defrost Mode Air comes from the windshield and side window
demist outlets. Use DEFROST mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.

button. RECIRCULATION mode should only be used
temporarily. The recirculation symbol will illuminate in
the display when this button is selected. Push the button
a second time to turn off the RECIRCULATION mode
LED and allow outside air into the vehicle.
NOTE: In cold weather, use of the RECIRCULATION
mode may lead to excessive window fogging. The RE-
CIRCULATION mode is not allowed in the FLOOR, MIX
and DEFROST modes to improve window clearing op-
eration. Recirculation will be disabled automatically if
these modes are selected.
Rear Automatic Temperature Control (ATC) — If
Equipped
The Rear ATC System has floor air outlets at the rear of
the right side sliding door, and overhead outlets at each
outboard rear seating position. The system provides
heated air through the floor outlets or cool, dehumidified
air through the headliner outlets.

Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. Refer to “Cooling System”
286 UNDERSTANDING YOUR INSTRUMENT PANEL
Page 288 of 512

under “Maintenance Procedures” and to “Fluids, Lubri-
cants, and Genuine Parts” in “Maintaining Your Vehicle”
for information pertaining to the cooling system and
coolant selection.
Winter Operation
Use of the air Recirculation mode during Winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem, increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Side Window Demisters
A side window demister outlet is located at each end of
the instrument panel. These non-adjustable outlets direct
air toward the side windows when the system is in the
Floor, Mix, or Defrost mode. The air is directed at the area
of the windows through which you view the outside
mirrors.
