Integrated HomeLink® Wireless Control
System
The HomeLink® Wireless Control System
provides a convenient way to replace
up to three hand held radio-frequency
transmitters used to activate compatible
devices such as gate operators, garage
door openers, entry door locks, security
systems, and home lighting.
NOTICE
HomeLink® operates while the ignition
switch is in the ACC or ON position
for safety reasons. It is to prevent
unintentional security problems from
happening when the vehicle is parked
outside the garage.
WARNING
Before programming HomeLink® to a
garage door opener or gate operator,
make sure people and objects are out
of the way of the device to prevent
potential harm or damage. Do not
use the HomeLink® with any garage
door opener that lacks the safety
stop and reverse features required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an
object - signaling the door to stop and
reverse - does not meet current U.S.
federal safety standards. Using a garage
door opener without these features
increases the risk of serious injury or
death.
For more information, contact
HomeLink® at www.homelink.com, or
call Home-Link customer support at
1-800-355-3515.
It is also recommended that a new
battery be replaced in the handheld
transmitter of the device being trained
to HomeLink® for quicker training and
accurate transmission of the radio
frequency. 1. Programming HomeLink
®
The following steps show how to
program HomeLink. If you have any
questions or are having difficulty
programming your HomeLink buttons,
refer to the HomeLink website or call the
HomeLink customer support toll-free
number. Do this before going back to the
dealer who sold you the car.

3) Two-Way Communication
Pr
ogramming (For select garage door
openers)
If your garage door opener has the
‘myQ’ logo on its side, your opener
likely has Two-Way Communication
capability. HomeLink has the capability
to establish Two-Way Communication
with your garage door opener. HomeLink
can receive and display “closing”
or “opening” status messages from
compatible garage door openers. At
any time, Home-Link can also recall
and display the last recorded status
communicated by the garage door
opener to indicate your garage door
being “closed” or “opened”.
To check if your garage door opener is
compatible with this feature, refer to
www.homelink.com/compatible/Two-
way-Communication. If your garage
door opener has this functionality, AND
the Two-Way Communication indicators
(4), (6) in the mirror appear while the
garage door is opening/closing, then
no further steps are needed. Two-Way
Communication Programming is already
complete. However, if your garage door
opener has this functionality, AND the
Two-Way Communication indicators (4),
(6) in the mirror DO NOT appear while
the garage door is opening/closing, use
the following instructions to enable this
functionality.
1.
In your v
ehicle, press and hold the
programmed HomeLink button for 2
seconds, then release. Confirm that
the garage door is moving. AFTER it
stops, you will have one minute to
complete the following steps:

2. On your garage door opener in your
garage, locate the “Learn” button
(usually near where the hanging
antenna wire is attached to the garage
door opener). If there is difficulty
locating this button, reference the
device’s owner’s manual.

Press and r
elease the “Learn” button.

our garage door opener
may flash, and your Two-Way
Communication indicators (4), (6) in

5.
Re
turn to the vehicle and firmly
press and release the programmed
HomeLink button to activate
your garage door. The Two-Way
Communication indicators (4), (6)
flash in orange when the door is
moving. Do not make any additional
button presses until AFTER the garage
door has come to a complete stop.
6.
Your T
wo-Way Communication
programming is now complete.
Information
If your garage door opener has Two-
Way Communication functionality,
it is possible for HomeLink to stop
functioning the garage door shortly
after initial programming, IF the Two-
Way Communication Programming
wasn’t properly completed. This
usually happens after the first 10 times
a programmed HomeLink button is
pressed. If you experience this, completing
the “Programming a New HomeLink
Button” and “Two-Way Communication
Programming” will restore door
operation.
4) Canadian Pr ogramming
Canadian radio-frequency laws require
transmitter remote signals to “time-
out” (or quit) after a couple seconds of
transmission, which may not be long
enough for HomeLink to pick up the signal
during programming.
If you live in Canada or you are having
difficulties programming a gate operator
or garage door opener by using the
programming procedures, replace
“Programming a New HomeLink Button”
step 3 with the following:
While the HomeLink indicator light (7) is
flashing orange, press and release (“cycle”)
your device’s handheld remote every two
seconds until the HomeLink indicator light
(7) changes from orange to green. You may
now release the hand-held remote button.
Then proceed with “Programming a New
HomeLink Button” step 4.

WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the
oil or for any other purpose. If you hear a change in the sound of the exhaust or if you
drive over something that strikes the underneath side of the vehicle, we recommend
that the exhaust system be checked as soon as possible by an authorized HYUNDAI
dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous
practice. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at “Fresh” and fan
control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the liftgate open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at “Fresh”, the air flow control at “Floor” or “Face”, and the fan
control set to high.
