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.

Release both buttons after the indicator
light changes from slow to rapid.
5. Push and hold the programmed HomeLink® button and observe the
indicator light.
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the
HomeLink® button is pushed.
To program the two remaining Home -
Link® buttons, repeat each step for each
remaining button. DO NOT erase the
channels.
CANADIAN/GATE OPERATOR
P
ROGRAMMING
For programming transmitters in Canada/
United States that require the transmitter
signals to “time-out” after several seconds of
transmission:
Canadian Radio Frequency (RF) laws require
transmitter signals to time-out (or quit) after
several seconds of transmission, which may not
be long enough for HomeLink® to pick up the
signal during programming. Similar to this Canadian law, some U.S. gate
operators are designed to time-out in the same
manner.
It may be helpful to unplug the device during the
cycling process to prevent possible overheating
of the garage door or gate motor.

1. Place the ignition in the ON/RUN position.

NOTE:
For vehicles equipped with Keyless Enter-N-Go,
place the ignition in the RUN position with the
engine on. Make sure while programming
HomeLink® with the engine on that your vehicle
is outside of your garage, or that the garage
door remains open at all times.
2. Place the hand-held transmitter 1 to
3 inches (3 to 8 cm) away from the
HomeLink® button you wish to program
while keeping the HomeLink® indicator
light in view.
3. Continue to push and hold the HomeLink® button while you push and release (“cycle”)
your hand-held transmitter every two
seconds until HomeLink® has successfully
accepted the frequency signal. The indicator light will flash slowly and then
rapidly when fully trained.
4. Watch for the HomeLink® indicator to change flash rates. When it changes, it is
programmed. It may take up to 30 seconds
or longer in rare cases. The garage door
may open and close while you are
programming.
5. Push and hold the programmed HomeLink® button and observe the
indicator light.
NOTE:
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the Home -
Link® button is pushed.
To program the two remaining HomeLink®
buttons, repeat each step for each remaining
button. DO NOT erase the channels.
If you unplugged the garage door opener/
device for programming, plug it back in at this
time.
