PROGRAMMING HOMELINK® TO A
M
ISCELLANEOUS DEVICE
The procedure on how to program HomeLink® to a
miscellaneous device follows the same procedure as
programming to a garage door opener
Úpage 54. Be sure
to determine if the device has a rolling code, or non-rolling
code before beginning the programming process.
NOTE:Canadian Radio Frequency (RF) laws require transmitter
signals to time-out (or quit) after several seconds of trans -
mission, 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. The procedure may need to
be performed multiple times to successfully pair the
device to your HomeLink® buttons.
REPROGRAMMING A SINGLE
H
OMELINK® BUTTON
To reprogram a single HomeLink® button that has been
previously trained, without erasing all the channels,
proceed as follows. Be sure to determine whether the new
device you want to program the HomeLink® button to has
a rolling code, or non-rolling code.

1. Place the ignition in the ON/RUN position, without
starting the engine.

2. Push and hold the desired HomeLink® button until the HomeLink® indicator light begins to flash after
20 seconds. Do not release the button.
3. Without releasing the button , proceed with Step 2 in
“Programming HomeLink® To A Garage Door
Opener” and follow all remaining steps.
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. 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.
WARNING!
Your motorized door or gate will open and close while
you are programming the universal transmitter. Do
not program the transmitter if people or pets are in
the path of the door or gate.
 Do not run your vehicle in a closed garage or
confined area while programming the transmitter.
Exhaust gas from your vehicle contains carbon
monoxide (CO) which is odorless and colorless.
Carbon monoxide is poisonous when inhaled and
can cause you and others to be severely injured or
killed.

REAR CLIMATE CONTROL OFF
To turn the rear climate controls off, push the
OFF button below the rear climate control
display, or if equipped, press and release the
OFF button on the Rear Comfort And
Convenience Display touchscreen, near the blower
buttons.
AUTOMATIC TEMPERATURE CONTROL
(ATC)
Automatic Operation

1. Push the AUTO button on the front climate control
display, and the word “AUTO” will illuminate along
with two temperatures for the driver and front
passenger. The system will then automatically
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 setting.
Manual Operation Override
This system offers a full complement of manual override
features. The AUTO symbol in the front climate control
display will no longer be illuminated 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.
CLIMATE VOICE RECOGNITION
Adjust vehicle temperatures hands-free and keep
everyone comfortable while you keep moving ahead (If
vehicle is equipped with climate control).
Push the VR/Phone button . After the beep, say one of
the following commands:

“Set the driver temperature to 70 degrees”
 “Set the passenger temperature to 70 degrees”
Did You Know: Voice Command for Climate may only be
used to adjust the interior temperature of your vehicle.
Voice Command will not work to adjust the heated seats
or steering wheel if equipped.
OPERATING TIPS
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. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling system is
functioning properly and the proper amount, type, and
concentration of coolant is used. Use of the Air
Recirculation mode during Winter months is not
recommended, because it may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control system
when the vehicle is being stored for an extended period of
time, see
Úpage 368.
CAUTION!
Interior air enters the Rear 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 rear
doors. 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.
