Information
An inappropriately disposed battery can be harmful to the
environment and human health. Dispose of the battery according
to your local law(s) or regulation.
IC WARNING
This device complies with Industry
Canada licence-exempt RSS
standard(s).
Operation is subject to the following
two conditions: (1) this device may not
cause interference, and (2) this device
must accept any interference, including
interference that may cause undesired
operation of the device.
Immobilizer System
The immobilizer system protects your
vehicle from theft. If an improperly
coded key (or other device) is used, the
engine’s fuel system is disabled.
When the ignition switch is placed in
the ON position, the immobilizer system
indicator should come on briefly, then
go off. If the indicator starts to blink, the
system does not recognize the coding
of the key. Turn the ignition switch to
the LOCK/OFF position, then turn the
ignition switch to the ON position again.
In some circumstances, the vehicle may
not recognize your smart key if another
smart key device is nearby or a metal
object such as a key chain is causing
interference with the smart key.
If this occurs, your vehicle may not
start. Remove any metal objects or
additional keys near the smart key before
attempting to start the vehicle again.
If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
immobilizer password is a customer
unique password and should be kept
confidential.
NOTICE
The transponder in your key is an
important part of the immobilizer
system. It is designed to give years
of trouble-free service, however you
should avoid exposure to moisture,
static electricity and rough handling.
Immobilizer system malfunction could
occur.

Information
This device complies with Industry Canada RSS-210 standard.
Operation is subject to the following three conditions: 1. This device may not cause harmful
interference.
2. This device must accept any
interference received, including
interference that may cause undesired operation.
3. Changes or modifications not expressly
approved by the party responsible
for compliance could void the user’s authority to operate the device.
“Limp Home” Mode and Related
Procedures
If the immobilizer warning indicator
blinks for five seconds when the ignition
key is turned to the “ON” position,
this indicates the immobilizer system
requires service. The engine cannot be
started without using the procedure
below.
The following procedure describes
how to start the engine using the limp
home function (0, 1, 2, 3 as a sample
password).
NOTICE
You can get a limp home password
when the vehicle is first delivered to
you. If you do not have a password,
consult your authorized HYUNDAI
dealer.
1. To activate the password, turn the ignition key “ON” and “OFF“
according to the digit numbers. The
immobilizer indicator will blink along
with the operation of the ignition
key. For example, turn the ignition
key once for digit number “1”, and
twice for “2”, and so on. For the digit
number “0”, you must cycle the
ignition key 10 times.
2. Wait for 3~10 seconds.
3. You may set the remaining number of digits by following steps 1 and 2.
4. If all of the four password digits have
been successfully entered, turn the
ignition key “ON” and check that the
immobilizer indicator illuminates.
From this time, you have to start your
engine within 30 seconds. If you try
to start your engine after 30 seconds,
your engine will not start.
NOTICE
If the engine stalls while driving in the
“limp home” mode, you can start your
engine within 3 seconds without re-
entering the password.
If the immobilizer indicator blinks for
five seconds, you must re-enter the
password (steps 1~4).
After performing the limp home
activation procedure, consult with your
authorized HYUNDAI dealer as soon as possible.
CAUTION
• If the password is entered incorrectly
three consecutive times, wait for
about one hour to perform the limp
home activation procedure again.
• If you cannot start your engine using
the limp home activation procedure,
have your vehicle towed by an
authorized HYUNDAI dealer.

CAUTION
• The system does not actually detect
objects or people in the rear seat. By
using a rear door opened and closed
history, the system indicates that
there may be something in the rear
seat.
• The rear door opened and closed
history can be initialized only when
you turn off the engine normally, get
off the vehicle and lock the door with
the remote control key. Therefore,
there could be alarms even though
the back doors are locked.

after the alarm sounds, there could
be the alarm sounds if you turn off
the engine and open the driver’s seat
door.

It does not use the actual sensors but it
provides the alarm sounds by checking
the rear door lock/unlock status as a
reminder.

Automatic-Dimming Night Vision Safety™ (NVS®
) Mirror (if equipped)
The NVS® Mirror automatically reduces
glare by monitoring light levels in the
front and the rear of the vehicle. Any
object that obstructs either light sensor
will degrade the automatic dimming
control feature.
For more information regarding NVS®
mirrors and other applications, please
refer to the Gentex website:
www.gentex.com
Your mirror will automatically dim
upon detecting glare from the vehicles
traveling behind you.
The mirror defaults to the ON position
each time the vehicle is started. Integrated HomeLink ®
Wireless Control
System
The HomeLink® Wireless Control System
can replace up to three hand-held
radio-frequency (RF) transmitters with
a single built-in device. This innovative
feature will learn the radio frequency
codes of most current transmitters to
operate devices such as gate operators,
garage door openers, entry door locks,
security systems, even home lighting.
Both standard and rolling code-equipped
transmitters can be programmed by
following the outlined procedures.
Additional HomeLink® information can
be found at: www.homelink.com, www.
youtube.com/HomeLinkGentex or by
calling 1-800-355-3515.
Retain the original transmitter of the
RF device you are programming for use
in other vehicles as well as for future
HomeLink® programming. It is also
suggested that upon the sale of the
vehicle, the programmed HomeLink®
buttons be erased for security purposes.
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
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
federal safety standards.Using a garage
door opener without these features
increases the risk of serious injury or
death.
Programming HomeLink ®
Please note the following:
• When programming a garage door opener, it is advised to park the
vehicle outside of the garage.
• It is recommended that a new battery be placed in the hand-held transmitter
of the device being programmed to
HomeLink® for quicker training and
accurate transmission of the radio-
frequency signal.
• Some vehicles may require the Engine Start/Stop button to be in the
ACC (or “Accessories”) position for
programming and/or operation of
HomeLink®.
• In the event that there are still programming difficulties or questions
after following the programming steps
listed below, contact HomeLink® at:
www.homelink.com, www.youtube.
com/HomeLinkGentex or by calling
1-800-355-3515.
