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 if the new device
you want to program the HomeLink® button to has a
rolling code or a 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 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.

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 press and hold the HomeLink® button, while you press 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. Press 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
pressed.
 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.
NOTE:The universal garage door opener only operates when the
engine is running for security reasons associated with
removable tops and doors.

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 359.
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 plenum, 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.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control system may
automatically adjust airflow to maintain cabin comfort.
Customer settings will be maintained upon return to an
engine running condition.
