REPROGRAMMING A SINGLE
H
OMELINK® BUTTON
To reprogram a single HomeLink® button that has been
previously trained, without erasing all the channels, refer
to the following procedure. 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”
Úpage 44, 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.
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, program -
ming is complete and the garage door/device
should activate when the HomeLink® 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.
Reprogramming A Single HomeLink® Button
(Canadian/Gate Operator)
To reprogram a channel that has been previously trained,
follow these steps:

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

2. Press and hold the desired HomeLink® button until
the indicator light begins to flash after 20 seconds.
Do not release the button.
3. Without releasing the button, proceed with “Canadian/Gate Operator Programming” Step 2 and
follow all remaining steps.
SECURITY
It is advised to erase all channels before you sell or turn in
your vehicle.
To do this, push and hold the two outside buttons for
20 seconds until the indicator flashes. Note that all
channels will be erased. Individual channels cannot be
erased.
The HomeLink® Universal Transceiver is disabled when
the Vehicle Security system is active.

temperature.
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 for
cold or hot vehicles. The system automatically adjusts
the temperature, mode, and blower speed to provide
comfort as quickly as possible.
 The temperature can be displayed in US or Metric units
by selecting the US/Metric customer-programmable
feature within Uconnect Settings
Úpage 191.
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 blower will increase in
speed and transition into Auto mode.
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.
CLIMATE VOICE RECOGNITION —
I
F EQUIPPED
Adjust vehicle temperatures hands-free and keep
everyone comfortable while you keep moving ahead.
Push the VR button on the steering wheel. After the beep,
say one of the following commands:
 “Set driver temperature to 70 degrees”
 “Set 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 387.
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 air distribution box, they could plug the water
drains. In Winter months, make sure the air intake is clear
of ice, slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and pollen
from the air. Contact an authorized dealer to service your
cabin air filter, and to have it replaced when needed.
