Your HYUNDAI should not be modified in any way.
Such modifications may adversely affect the per-
formance, safety or durability of your HYUNDAI
and may, in addition, violate conditions of the lim-
ited warranties covering the vehicle. Certain mod-
ifications may also be in violation of regulations
established by the U.S. Department of
Transportation and other federal or state agencies.
Your vehicle is equipped with electronic fuel injec-
tion and other electronic components. It is possible
for an improperly installed/adjusted two-way radio
or cellular telephone to adversely affect electronic
systems. For this reason, we recommend that you
carefully follow the radio manufacturer’s instruc-
tions or consult your HYUNDAI dealer for precau-
tionary measures or special instructions if you
choose to install one of these devices.

ger seat wearing heavily
padded clothes such as
ski wear and hip protec-
tor.
Do not use car seat
accessories such as thick
blankets and cushions
which cover up the car
seat surface.
Do not place electronic
devices such as laptops,
DVD player, or conductive
materials such as water
bottles on the passenger
seat.

When changing or replacing the seat or seat cover, use original items only. The OCS has been devel-
oped based on using original HYUNDAI car seats only. Altering or changing the authentic parts may
result in system malfunction and increase risk of injury when in collision. Any of the above could inter-
fere with the proper operation of the OCS sensor thereby increasing the risk of an injury in an accident.

Automatic-Dimming Night Vision
Safety™ (NVS®) Mirror
(if equipped)
The NVS®Mirror automatically
reduces glare by monitoring light lev-
els 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 applica-
tions, please refer to the Gentex
website:
www.gentex.com Your mirror will automatically dim
upon detecting glare from the vehi-
cles traveling behind you. The auto-
dimming function can be controlled
by pressing the Dimming ON/OFF
button:

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 out-
lined procedures.
Additional HomeLink
®information
can be found at: www.homelink.com
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.

Programming HomeLink®
Please note the following:
When programming a garage dooropener, it is advised to park the
vehicle outside of the garage.
It is recommended that a new bat- tery be placed in the hand-held
transmitter of the device being pro-
grammed to HomeLink
®for quicker
training and accurate transmission
of the radio-frequency signal.
Some vehicles may require the ignition switch to be placed in the
ACC (or "Accessories") position for
programming and/or operation of
HomeLink
®.
In the event that there are still pro- gramming difficulties or questions
after following the programming
steps listed below, contact
HomeLink
®at: www.homelink.com
or by calling 1-800-355-3515.
Programming

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 pre-
vent 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.
