1. Press the Rear Temperature Lock button on the frontATC panel. This turns off the Rear Temperature Lock
icon in the rear temperature knob. 2. Rotate the Rear Blower, Rear Temperature and the
Rear Mode Control knobs to suit your comfort needs.
3. ATC is selected by adjusting the rear blower knob counterclockwise to AUTO.
Once the desired temperature is displayed, the ATC
System will automatically achieve and maintain that
comfort level. 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.
Rear Blower Control
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.
Rear Temperature Control
To change the temperature in the rear of the vehicle,
rotate the temperature knob counterclockwise to lower
the temperature, and clockwise to increase the tempera-
ture. The rear temperature settings are displayed in the
front ATC panel.
When rear controls are locked by the front system, the
Rear Temperature Lock symbol on the temperature knob
is illuminated and any rear overhead adjustments are
ignored.
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.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
OAT coolant (conforming to MS-12106) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended, because it
may cause window fogging.
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.
A/C Air Filter
On vehicles equipped with Automatic Temperature Con-
trol (ATC), the climate control system filters out dust and
pollen from the air. Refer to “Air Conditioning” in
“Maintaining Your Vehicle” for filter replacement instruc-
tions.
