To change the temperature in the rear of the vehicle,

rotate the temperature control knob counterclockwise for

cold air, and clockwise for heated air.

Bi-Level Mode

Air comes from both the headliner outlets and the

floor outlets.

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.

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.

The rear airflow modes will mirror the front unit opera-

tion. Rear PANEL mode is automatically selected when

the front control is in the PANEL mode. When the front Floor Mode

unit is in BI-LEVEL mode, airflow will be emitted from

Automatic Operation

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.

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.

•

The temperature can be displayed in U.S. or Metric

units by selecting the US/M customer-programmable

feature. Refer to the “Electronic Vehicle Information

Center (EVIC) — Customer-Programmable Features”

in this Section of the manual.

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.

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.

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.

Rear Automatic Three-Zone Temperature Control

(ATC) — If Equipped

Rear second row occupants can only adjust the rear ATC

control when the REAR LOCK button is turned off.

The Rear Automatic Three Zone Temperature Control

(ATC) system has floor air outlets at the rear of the right

side sliding door, and overhead outlets at each outboard

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. A solution of 50% ethylene

glycol antifreeze coolant and 50% water is recommended.

Refer to “Maintenance Procedures” in “Maintaining Your

Vehicle” for proper coolant selection.
