B230G03Y-AATInstallation on Rear Seats
To install a child restraint system in the rear
seats, extend the shoulder/lap belt entirely from
its retractor until a "click" is felt. This will engage
the seat belt retractor automatic locking feature,
which allows the seat belt to retract but not
extend. Install the child restraint system, buckle
the seat belt and allow the seat belt to take up
any slack. Make sure that the lap portion of the
belt is tight around the child restraint system and
the shoulder portion of the belt is positioned so
that it cannot interfere with the child's head or
neck. Also, double check to be sure that the
retractor has engaged the Automatic Locking
feature by trying to extend webbing out of the
retractor. If the retractor is in the Automatic
Locking mode, the belt will be locked. After
installation of the child restraint system, try to
move it in all directions to be sure the child
restraint system is securely installed. If you need
to tighten the belt, pull more webbing toward the
retractor. When you unbuckle the seat belt and
allow it to retract, the retractor will automatically
revert back to its normal seated passenger
Emergency Locking usage condition.

WARNING:
If the child restraint seat is not anchored
properly, the risk of a child being seriously
injured or killed in a collision greatly in-
creases. Follow the child seat manufacturer's instruc-
tions to properly install safety seats with ISOFIX
or ISOFIX-compatible attachments.
Once you have installed the ISOFIX child re-
straint seat, assure that the seat is properly
attached to the ISOFIX and tether anchors.
Also, test the safety seat before you place the
child in it. Tilt the seat from side to side. Also try
to tug the seat forward. Check to see if the
anchors hold the seat in place.

WARNING:
o Do not modify or replace the front pas-
senger seat. Don't place anything on or
attach anything such as a blanket or
after market seat heater to the front
passenger seat. This can adversely af-
fect the occupant classification system.
o Do not sit on sharp objects such as tools
when occupying the front passenger
seat. This can adversely affect the occu-
pant classification system.
o Do not use accessory seat covers on the
front seats.
o Accident statistics show that children
are safer if they are restrained in the rear,
as opposed to the front seat. It is recom-
mended that child restraints be secured
in a rear seat, including an infant riding
in a rear-facing infant seat, a child riding
in a forward-facing child seat and an
older child riding in a booster seat.
!
WARNING:
o A smaller-stature adult who is not seated
correctly (for example: seat excessively
reclined, leaning on the center console,
or hips shifted forward in the seat) can
cause a condition where the advanced
frontal airbag system senses less weight
than if the occupant were seated prop-
erly (sitting upright with the seatback in
an upright position, centered on the seat
cushion with their seat belt on, legs
comfortably extended and their feet on
the floor). This condition can result in an
adult potentially being misclassified and
illumination of the "PASSENGER AIR
BAG OFF" indicator.
B990B04Y-AATSide Impact Airbag (If installed)Your Hyundai is equipped with a side impact
airbag in each front seat. The purpose of the
airbag is to provide the vehicle's driver and/or
the front passenger with additional protection
than that offered by the seat belt alone. The side
impact airbags are designed to deploy only
during certain side-impact collisions, depend-
ing on the crash severity, angle, speed and point
of impact. The side impact airbags are not
designed to deploy in all side impact situations.

Integrated HomeLink
® Wireless Control
System
The HomeLink
® Wireless Control System pro-
vides a convenient way to 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
or by calling 1-800-355-3515.
CAUTION:
Before programming HomeLink
® to a ga-
rage door opener or gate operator, make
sure that people and objects are out of the
way of the device to prevent potential harm
or damage. Do not use HomeLink® with any
garage door opener that lacks the safety
stop and reverse features as required by
U.S. federal safety standards (this includes
any garage door opener model manufac-
tured 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 fea-
tures increases the risk of serious injury or
death.Programming HomeLink
®
NOTE:o When programming a garage door
opener, it is advised to park the vehicle
outside of the garage.
o 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 ac-
curate transmission of the radio-fre-
quency signal.
o Some vehicles may require the ignition
switch to be turned to the second (or
"accessories") position for program-
ming and/or operation of HomeLink.
o In the event that there are still program-
ming difficulties or questions after fol-
lowing the programming steps listed
below, contact HomeLink
® at:
www.homelink.com or 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:
o If you open the fuel filler cap during high
ambient temperatures, a slight "pres-
sure sound" may be heard. This is nor-
mal and not a cause for concern.
Whenever you open the fuel filler cap,
turn it slowly.
o Make sure the fuel filler cap is replaced
and securely seated after fueling. Failure
to replace or fully seat the fuel filler cap
will result in fuel vapors escaping into
the atmosphere and the check engine
" " indicator illuminating.
o Do not "TOP-OFF" after the first nozzle
shut off when refueling.
o Automotive fuels are flammable/explo-
sive materials. When refueling, please
note the following guidelines carefully.
- Before touching the fuel nozzle or fuel
filler cap, have one's hands in contact

!
WARNING:
- Do not get back in the vehicle while
refueling. Do not operate anything that
can produce static electricity. Static
electricity discharge can ignite fuel
vapors resulting in an explosion.
- When using a portable fuel container,
be sure to place the container on the
ground while refueling. Static electric-
ity discharge from the container can
ignite fuel vapors causing a fire. While
starting refueling, contact should be
maintained until the filling is complete.
- Do not use cellular phones around a
gas station. The electric current or elec-
tronic interference from cellular phones
can ignite fuel vapors causing a fire.
- When refueling, always turn the engine
off. Sparks by engine compartment
electrical equipment can ignite fuel
vapors causing a fire. After refueling,
check to make sure the fuel filler cap is
securely closed, and then start the
engine.
