GETTING TO KNOW YOUR VEHICLE 69
AUTOMATIC TEMPERATURE CONTROL
(ATC)
Automatic Operation
1. Push the AUTO button on the front
Automatic Temperature Control (ATC)
Panel and the word “AUTO” will illuminate
in the front ATC display, along with two
temperatures for the driver and front
passenger. The system will then automat-
ically regulate the amount of airflow.
2. Adjust the temperature you would like the
system to maintain, by adjusting the driver,
passenger, and rear temperatures. 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. The system automatically adjusts the
temperature, mode and fan speed to provide
comfort as quickly as possible.
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 changing the
front blower knob setting.
Manual Operation Override
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:
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.
OPERATING TIPS
NOTE:
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect
against engine overheating. A solution of 50%
OAT (Organic Additive Technology) coolant that
meets the requirements of FCA Material
Standard MS.90032 and 50% water is
recommended. Refer to “Fluids and Lubricants”
in “Technical Specifications” for proper coolant
selection.
Winter Operation
Use of the Air Recirculation mode during Winter
months is not recommended because it may
cause window fogging.
