WARNING:
o A child restraint system must be placed
in the rear seat. Never install a child or
infant seat on the front passenger's seat.
Should an accident occur and cause the
passenger side airbag to deploy, it could
severely injure or kill an infant or child
seated in an infant or child seat. Thus
only use a child restraint in the rear seat
of your vehicle.
o A safety belt or child restraint system
can become very hot if it is left in a closed
vehicle on a sunny day, even if the out-
side temperature does not feel hot. Be
sure to check the seat cover and buckles
before placing a child there.
o When the child restraint system is not in
use, store it in the trunk or fasten it with
a safety belt so that it will not be thrown
forward in the case of a sudden stop or
an accident.
o Children who are too large to be in a child
restraint should sit in the rear seat and be
restrained with the available lap/shoul-
der belts. Never allow children to ride in
the front passenger seat.
B220C02A-GATTo Release the Seat BeltWhen you want to release the seat belt, press
the button in the locking buckle.
!
WARNING:
When fastening the outboard seat belts or
the center seat belt, make sure they are
inserted into the correct buckles to obtain
maximum protection from the seat belt
system and assure proper operation.
CHILD RESTRAINT SYSTEMB230A03Y-AATChildren riding in the car should sit in the rear
seat and must always be properly restrained to
minimize the risk of injury in an accident, sudden
stop or sudden maneuver. According to acci-
dent statistics provided by the National High-
way Traffic Safety Administration (NHTSA),
children are safer when properly restrained in
the rear seats than in the front seat. Larger
children not in a child restraint should use one
of the seat belts provided.
All 50 states have child restraint laws. You
should be aware of the specific requirements in
your state. Child and/or infant safety seats must
be properly placed and installed in the rear seat.
You must use a commercially available child
restraint system that meets the requirements of
the Federal Motor Vehicle Safety Standards
(FMVSS).
Children could be injured or killed in a crash if
their restraints are not properly secured. For
small children and babies, a child seat or infant
seat must be used. Before buying a particular
child restraint system, make sure it fits your car
seat and seat belts, and fits your child. Follow
all the instructions provided by the manufac-
turer when installing the child restraint system.

WARNING:
o Always make sure that the shoulder belt
portion of the lap/shoulder belt is posi-
tioned midway over the shoulder and
never across the neck or behind the
back. Moving the child closer toward the
seat belt buckle may help provide a good
shoulder belt fit. The lap belt portion of
the lap/shoulder belt must always be
positioned as low as possible on the
child's hips, and as snug as possible.
o If the seat belt will not properly fit the
child, Hyundai recommends the use of
an approved booster seat in the rear seat
in order to raise the child's seating height
so that the seat belt will properly fit the
child.
Before purchasing a booster seat, make
sure that it meets applicable Federal
Motor Vehicle Safety Standards (FMVSS)
and that it is satisfactory for use with this
vehicle.
o Never allow a child to stand up or kneel
on the seat.
o Never use an infant carrier or a child
safety seat that "hooks" over a seatback;
it may not provide adequate security in
an accident.
WARNING:
o Never allow a child to be held in a person's
arms while they are in a moving vehicle,
as this could result in serious injury to
the child in the event of an accident or a
sudden stop. Holding a child in a moving
vehicle does not provide the child with
any means of protection during an acci-
dent, even if the person holding the child
is wearing a seat belt.

B230B01NF-AATUsing a Child Restraint SystemFor small children and babies, the use of a child
seat or infant seat is required. This child seat or
infant seat should be of appropriate size for the
child and should be installed in accordance with
the manufacturer's instructions. It is further
required that the seat be placed in the vehicle's
rear seat. Your vehicle is provided with three
child restraint hook holders for installing the
child seat or infant seat.

!For vehicles with adjustable headrests, route
the tether strap under the headrest and
between the headrest posts, otherwise route
the tether strap over the top of the seatback.
3. Connect the tether strap hook to the child
restraint hook holder and tighten to secure
the seat.
WARNING:
Do not mount more than one child restraint
to a single tether or to a child restraint lower
anchorage point. The improper increased
load may cause the anchorage points or
tether anchor to break, causing serious
injury or death.

B230D03E-AATSecuring the Child Restraint Seat with
the "ISOFIX" systemSome child seat manufacturers make safety
seats that are labeled as ISOFIX or ISOFIX-
compatible child seats. These seats include two
rigid or webbing mounted attachments that
connect to two ISOFIX anchors at specific
seating positions in your vehicle. This type of
child seat eliminates the need to use seat belts
to attach the child seat for forward-facing child
seats.
ISOFIX anchors have been provided in your
vehicle. The ISOFIX anchors are located in the
left and right outboard rear seating positions.
Their locations are shown in the illustration.
There is no ISOFIX anchor provided for the
center rear seating position.
B230D01NF
The ISOFIX anchors are located between the
seatback and the seat cushion of the rear seat
left and right outboard seating positions.
!
WARNING:
o Do not install a child restraint seat at the
center of the rear seat using the vehicle's
ISOFIX anchors. The ISOFIX anchors are
only provided for the left and right out-
board rear seating positions. Do not
misuse the ISOFIX anchors by attempt-
ing to attach a child safety seat in the
middle of the rear seat position to the
ISOFIX anchors. In a crash, the child seat
ISOFIX attachments may not be strong
enough to secure the child restraint seat
properly in the center of the rear seat and
may break, causing serious injury or
death.
o Do not mount more than one child re-
straint to a single tether or to a child
restraint lower anchorage point. The
improper increased load may cause the
anchorage points or tether anchor to
break, causing serious injury or death.
o Attach the ISOFIX or ISOFIX-compatible
child seat only to the appropriate loca-
tions shown.
o Always follow the installation and use
instructions provided by the manufac-
turer of the child restraint.

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 If the retractor is not in the Automatic
Locking mode, the child restraint sys-
tem can move when your vehicle turns or
stops abruptly.
o Do not install any child restraint system
in the front passenger seat. Should an
accident occur and cause the passenger
side airbag to deploy, it could severely
injure or kill an infant or child seated in
an infant or child seat. Therefore, only
use a child restraint system in the rear
seat of your vehicle.NOTE:o Before installing the child restraint sys-
tem in any seating position, read the
instructions supplied by the child re-
straint system manufacturer.
o If the seat belt does not operate as de-
scribed, have the system checked imme-
diately by your authorized Hyundai dealer.

B180B01NF-AATPre-tensioner Seat BeltYour Hyundai vehicle is equipped with driver's
and front passenger's pre-tensioner seat belts.
The purpose of the pre-tensioner is to make
sure that the seat belts fit tightly against the
occupant's body in certain frontal collisions.
The pre-tensioner seat belts can be activated
alone or, where the frontal collision is severe
enough, together with the airbags.
When the vehicle stops suddenly, or if the
occupant tries to lean forward too quickly, the
seat belt retractor will lock into position. In
certain frontal collisions, the pre-tensioner will
activate and pull the seat belt into tighter contact
against the occupant's body. The buckle pre-
HXG229
CAUTION:
Do not put anything near the buckle. Plac-
ing objects near the buckle can adversely
affect the buckle pre-tensioner and may
increase the risk of personal injury in the
event of a collision.
If the system senses excessive seat belt ten-
sion on the driver or passenger's seat belt when
the pre-tensioner activates, the load limiter
inside the pre-tensioner will release some of the
pressure on the affected seat belt.
The seat belt pre-tensioner system consists
mainly of the following components. Their loca-
tions are shown in the illustration: tensioner (which is installed in the buckle) will
also pull the seat belt into the buckle.

WARNING:
o No objects should be placed over or near
the airbag modules on the steering
wheel, instrument panel, and the front
passenger's panel above the glove box,
because any such object could cause
harm if the vehicle is in a crash severe
enough to cause the airbags to deploy.
o If the airbags deploy, they must be re-
placed by an authorized Hyundai dealer.
o Do not tamper with or disconnect SRS
wiring or other components of the SRS
system. Doing so could result in injury,
due to accidental deployment of the
airbags or by rendering the SRS inopera-
tive.
o Even though your vehicle is equipped
with the occupant classification sys-
tem, do not install a child restraint sys-
tem in the front passenger seat position.
A child restraint system must never be
placed in the front seat. The infant or
child could be severely injured or killed
by an airbag deployment in case of an
accident.
o Do not allow children to ride in the front
passenger seat. If older children (teen-
agers and older) must ride in the front
seat, make sure they are always properly
belted and the seat is moved back as far
as possible.
o For maximum safety protection in all
types of crashes, all occupants includ-
ing the driver should always wear their
seat belts whether or not an airbag is
also provided at their seating position to
minimize the risk of severe injury or
death in the event of a crash. Do not sit
or lean unnecessarily close to the airbag
while the vehicle is in motion.
o Sitting improperly or out of position can
result in serious or fatal injury in a crash.
All occupants should sit upright with
the seat back in an upright position,
centered on the seat cushion with their
seat belt on, legs comfortably extended
and their feet on the floor until the ve-
hicle is parked and the ignition key is
removed.
o The SRS airbag system must deploy very
rapidly to provide protection in a crash.
If an occupant is out of position because
of not wearing a seat belt, the airbag may
forcefully contact the occupant causing
serious or fatal injuries.

B990A01NF-AATOCCUPANT CLASSIFICATION SYSTEMYour vehicle is equipped with an occupant
classification system in the front passenger's
seat.
The Occupant Classification system is de-
signed to detect the presence of a properly-
seated front passenger and determine if the
passenger's front airbag should be enabled
(may inflate) or not. The driver's front airbag is
not affected or controlled by the Occupant
Classification system.
If the front passenger seat is occupied by a
person that the system determines to be of adult
size, and he/she sits properly (sitting upright
