HomeLink® replaces up to three
hand-held transmitters that operate
devices such as garage door
openers, motorized gates, lighting,
or home security systems. The
HomeLink® unit is powered by your
vehicle’s 12 Volt battery.
 The HomeLink® buttons that are located in the over -
head console or sunvisor designate the three different
HomeLink® channels.
 To operate HomeLink®, push and release any of the
programmed HomeLink® buttons. These buttons will
activate the devices they are programmed to with each
press of the corresponding HomeLink® button.
 The HomeLink® indicator light is located above the

NOTE:HomeLink® is disabled when the Vehicle Security system
is active Úpage 277.
BEFORE YOU BEGIN PROGRAMMING
H
OMELINK®
For efficient programming and accurate transmission of
the Radio Frequency (RF) signal, it is recommended that a
new battery be placed in the hand-held transmitter of the
device that is being programmed to the HomeLink®
system. Make sure your hand-held transmitter is
programmed to activate the device you are trying to
program your HomeLink® button to. Ensure that your vehicle is parked outside of the garage
before you begin programming.
It is recommended that you erase all the channels of your
HomeLink® before you use it for the first time.
ERASING ALL THE HOMELINK®
C
HANNELS
To erase the channels, follow this procedure:

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

2. Push and hold the two outside HomeLink® buttons
(I and III) for up to 20 seconds, or until the
HomeLink® indicator light flashes.
NOTE:Erasing all channels should only be performed when
programming HomeLink® for the first time. Do not erase
channels when programming additional buttons.
IDENTIFYING WHETHER YOU HAVE A
R
OLLING CODE OR NON-ROLLING CODE
D
EVICE
Before programming a device to one of your HomeLink®
buttons, you must determine whether the device has a
rolling code or non-rolling code. Rolling Code Devices
To determine if your device has a rolling code, a good
indicator is its manufacturing date. Typically, devices
manufactured after 1995 have rolling codes. A device with
a rolling code will also have a “LEARN” or “TRAIN” button
located where the antenna is attached to the device. The
button may not be immediately visible when looking at the
device. The name and color of the button may vary slightly
by manufacturer.
NOTE:The “LEARN” or “TRAIN” button is not the button you
normally use to operate the device.
Non-rolling Code Devices
Most devices manufactured before 1995 will not have a
rolling code. These devices will also not have a “LEARN” or
“TRAIN” button.
PROGRAMMING HOMELINK® TO A
G
ARAGE DOOR OPENER
To program any of the HomeLink® buttons to activate your
garage door opener motor, proceed as follows:
NOTE:All HomeLink® buttons are programmed using this
procedure. You do not need to erase all channels when
programming additional buttons.

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

2. Place the garage door opener 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.

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 transmitter is disabled when
the Vehicle Security system is active.

Loss of the battery charge may indicate one or more of the
following conditions:
The charging system cannot deliver enough electrical
power to the vehicle system because the electrical
loads are larger than the capability of the charging
system. The charging system is still functioning
properly.
 Turning on all possible vehicle electrical loads (e.g.
HVAC to max settings, exterior and interior lights,
overloaded power outlets +12 Volts, 115 Volts AC, USB
ports) during certain driving conditions (city driving,
towing, frequent stopping).
 Installing options like additional lights, upfitter elec -
trical accessories, audio systems, alarms and similar
devices.
 Unusual driving cycles (short trips separated by long
parking periods).
 The vehicle was parked for an extended period of time
(weeks, months).
 The battery was recently replaced and was not charged
completely.
 The battery was discharged by an electrical load left on
when the vehicle was parked.
 The battery was used for an extended period with the

+12 Volts portable appliances like vacuum cleaners,
game consoles and similar devices. What to do when an electrical load reduction action
message is present
(“Battery Saver On” or “Battery Saver Mode”)
During a trip:

Reduce power to unnecessary loads if possible:
 Turn off redundant lights (interior or exterior)
 Check what may be plugged in to power outlets
+12 Volts, 115 Volts AC, USB ports
 Check HVAC settings (blower, temperature)
 Check the audio settings (volume)
After a trip:
 Check if any aftermarket equipment was installed
(additional lights, upfitter electrical accessories, audio
systems, alarms) and review specifications if any (load
and Ignition Off Draw currents).
 Evaluate the latest driving cycles (distance, driving
time and parking time).
 The vehicle should have service performed if the
message is still present during consecutive trips and
the evaluation of the vehicle and driving pattern did not
help to identify the cause.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated message and/
or acoustic signal when applicable. These indications are
indicative and precautionary and as such must not be
considered as exhaustive. Always refer to the information

GETTING TO KNOW YOUR INSTRUMENT PANEL75
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have OBD II and a connection
port to allow access to information related to the
performance of your emissions controls. Authorized
service technicians may need to access this information to
assist with the diagnosis and service of your vehicle and
emissions system
Úpage 111.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and
Maintenance (I/M), this check verifies the
Malfunction Indicator Light (MIL) is functioning
and is not on when the engine is running, and
that the OBD II system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a dead battery or a battery
replacement. If the OBD II system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle's OBD II system is ready, you must do the following:

1. Cycle the ignition switch to the ON position, but do not crank or start the engine.

NOTE:If you crank or start the engine, you will have to start this
test over. 2. As soon as you cycle the ignition switch to the ON
position, you will see the Malfunction Indicator Light
(MIL) symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
 The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that
your vehicle's OBD II system is not ready and you
should not proceed to the I/M station.
 The MIL will not flash at all and will remain fully illu -
minated until you place the ignition in the off posi -
tion or start the engine. This means that your
vehicle's OBD II system is ready and you can
proceed to the I/M station.
If your OBD II system is not ready, you should see an
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your vehicle
as you normally would in order for your OBD II system to
update. A recheck with the previously mentioned test
routine may then indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system is
ready or not, if the MIL is illuminated during normal vehicle
operation you should have your vehicle serviced before
going to the I/M station. The I/M station can fail your
vehicle because the MIL is on with the engine running.
WARNING!
 ONLY an authorized service technician should
connect equipment to the OBD II connection port in
order to read the VIN, diagnose, or service your
vehicle.
 If unauthorized equipment is connected to the OBD II
connection port, such as a driver-behavior tracking
device, it may:
 Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
 Access, or allow others to access, information
stored in your vehicle systems, including
personal information.
