outlets at the rear of the right side sliding door, and
overhead outlets at each outboard rear seating position.
The unit provides warm or cool air through the floor and
upper outlets.

Only when the front control for the rear blower is in the
RRposition do the second row seat occupants have
control of the rear blower speed.
The rear blower control, located in the rear overhead
console, has an off position and a range of blower speeds.
This allows the second row seat occupants to control the
volume of air circulated in the rear of the vehicle.
CAUTION!
Interior air enters the Rear Manual Climate 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.
Rear Temperature Control
The rear mode selection RR,allows the settings to be
controlled by the rear mode control knob.
To change the temperature in the rear of the vehicle,
rotate the temperature control knob counterclockwise for
cold air, and clockwise for heated air.
When rear controls are locked by the front system, the
lock symbol on the temperature knob is illuminated, and
the rear overhead adjustments are inoperable.
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 ModeAir 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.
Automatic Temperature Control (ATC) —
If Equipped
•
Front Three-Zone ATC allows both driver and front
passenger seat occupant, and rear seat occupants to
select individual comfort settings.
•Occupants in the vehicle select AUTO mode operation
by a button press on the right rotary knob and a
comfort temperature setting using rotary knobs on the
control unit.
•The system can be controlled manually, if desired.
•SYNC feature links the controls for all three zones,
allowing one comfort setting (driver setting) for the
cabin, if desired.
The Three-Zone ATC System automatically maintains the
interior comfort level desired by the driver and all
passengers. The system automatically adjusts the air
temperature, the airflow volume, amount of outside air
recirculation and the airflow direction. This maintains a
comfortable temperature, even under changing condi-
tions.

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.

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.
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.

UNDERSTANDING YOUR INSTRUMENT PANEL 309

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.
NOTE: While operating in the other modes, the system
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. The SNOWFLAKE mode, or A/C button, allows
the operator to manually activate or deactivate the
air conditioning system. When in SNOWFLAKE
mode, and the ATC display is on cool, dehumidified air
flows through the air outlets. If ECONOMY mode is
desired, press the SNOWFLAKE button to turn off the
SNOWFLAKE mode in the ATC display, and deactivate
the A/C system.
NOTE:
•If the system is in Mix or Defrost Mode, the SNOW-
FLAKE 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.

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 mode control
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.
The REAR SYSTEM control for the Rear ATC System is
on the front lower ATC panel located on the instrument
panel.
Pressing the REAR LOCK button for the Rear ATC
System from the front lower ATC panel, illuminates a
LOCK symbol in the rear display. The rear temperature
and air source are controlled from the front lower ATC
panel.
Rear second row occupants can only adjust the rear ATC
control when the REAR LOCK button is turned off.
