Automatic Operation
1. Press the AUTO button on the front ATC Panel and the
words Front Auto will illuminate in the front ATC
display, along with two temperatures for the driver
and front passenger. 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 passenger,
and rear seat rotary temperature knobs. Once the de-
sired 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 experi-
ence 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.

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 until the engine warms up. The fan will engage
immediately if the Defrost mode is selected, or by chang-

Rear Mode Control
Headliner Mode
Air comes from the outlets in the headliner. Each
of these outlets can be individually adjusted to
direct the flow of air. Moving the air vanes of the outlets
to one side will shut off the airflow.Bi-Level Mode
Air comes from both the headliner outlets and the
floor outlets.
NOTE:In many temperature positions, the Bi-Level
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
Floor Mode
Air comes from the floor outlets.
Recirculation Control
When outside air contains smoke, odors, or high
humidity, or if rapid cooling is desired, you may
wish to recirculate interior air by pressing the
Recirculation control button. Recirculation mode
should only be used temporarily. A LED will illuminate on
the Recirculation control button when Recirculation mode 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 Recirculation
mode is not allowed in Defrost mode to improve window
clearing operation. Recirculation will be disabled auto-
matically if this mode is selected.
Manual Operation
This system offers a full complement of manual override
features. The AUTO symbol in the front ATC display will
be turned off when the system is being used in the
manual mode.
NOTE:Each of these features operate independently
from each other. If any one feature is controlled manually,
the temperature doors will continue to operate automati-
cally.Blower Control
There are seven fixed blower speeds.
Use the outer dial control to regulate the
amount of air forced through the system
in any mode you select. The blower
speed increases as you move the control
clockwise and decreases when you move
the control counter-clockwise.
The blower fan speed can be set to any fixed speed by
adjusting the blower control outer dial. 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 instru-
ment 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 Mode
Air 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 comfortable,
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.

will not automatically sense the presence of fog, mist or
ice on the windshield. DEFROST mode must be manually
selected to clear the windshield and side glass.
Air Conditioning (A/C)
•
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning sys-
tem. When in A/C mode and the ATC is set to a cool
temperature, dehumidified air flows through the air
outlets. If Economy mode is desired, press the A/C
button to turn off the A/C mode in the ATC display and
deactivate the A/C system.
NOTE:
•
If the system is in Mix, Floor or Defrost Mode, the A/C
can be turned off, but the A/C system shall remain active
to prevent fogging of the windows.
•If fog or mist appears on the windshield or side glass,
select Defrost mode and increase blower speed.
Rear Automatic Temperature Control (ATC) — If

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.
The rear system temperature control is on the front ATC
panel located on the instrument panel.
Pressing the Rear Temperature Lock button on the front
ATC panel, illuminates a lock symbol in the rear display.

The rear blower control knob can be manually set to off,
or any fixed blower speed, by rotating the knob from low
to high. This allows the rear seat occupants to control the
volume of air circulated in the rear of the vehicle.
CAUTION!
Interior air enters the Rear Automatic Temperature
Control System through an intake grille, located in
the right side trim panel behind the third row seats.
The heater outlets are located in the right side trim
panel, just behind the sliding door. Do not block or
place objects directly in front of the inlet grille or
heater outlets. The electrical system could overload
causing damage to the blower motor.

Vacation/Storage
Before 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
fresh air with the blower setting on high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower speed.
Do not use the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
Winter months, make sure the air intake is clear of ice,
slush, and snow.
