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 outside 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 may be seriously injured or
killed by an inflating airbag. All
children, even those too large for child
restraints, must ride in the rear seat.
!
WARNING:
To reduce the chance or serious or fatal
injuries:
o Children of all ages are safer when re-
strained in the rear seat. A child riding in
the front passenger seat can be force-
fully struck by an inflating airbag result-
ing in serious or fatal injuries.
o Always follow the instructions for instal-
lation and use of the child restraint maker.
o Always make sure the child seat is se-
cured properly in the car and your child
is securely restrained in the child seat.
o Never hold a child in your arms or lap
when riding in a vehicle. The violent
forces created during a crash will tear
the child from your arms and throw the
child against the car’s interior.
o Never put a seat belt over yourself and
a child. During a crash, the belt could
press deep into the child causing seri-
ous internal injuries.
o Never leave children unattended in a
vehicle – not even for a short time. The
car can heat up very quickly, resulting in
serious injuries to children inside. Even
very young children may inadvertently
cause the vehicle to move, entangle
themselves in the windows, or lock them-
selves or others inside the vehicle.o Never allow two children, or any two
persons, to use the same seat belt.
o Children often squirm and reposition
themselves improperly. Never let a
child ride with the shoulder belt under
their arm or behind their back. Always
properly position and secure children
in rear seat.
o Never allow a child to stand-up or
kneel on the seat or floor of a moving
vehicle. During a collision or sudden
stop, the child can be violently thrown
against the vehicle's interior, resulting
in serious injury.
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.
o Seat belts can become very hot, es-
pecially when the car is parked in
direct sunlight. Always check seat
belt buckles before fastening them
over a child.
o Always store or secure a child seat,
even when it is not in use. During a
collision or sudden stop, the child seat
could be thrown inside the vehicle.

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 head-
rest 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:
o A child can be seriously injured or
killed in a collision if the child restraint
is not properly anchored. Always
follow the child seat manufacturer’s
instructions for installation and use.
o Never mount more than one child re-
straint to a single tether or to a single
lower anchorage point. The increased
load caused by multiple seats may
cause the tethers or anchorage points
to break, causing serious injury or
death.
B230D06E-AATSecuring the Child Restraint Seat
with the "Child Seat Lower Anchor"
systemSome child seat manufacturers make safety
seats that are labeled as LATCH or LATCH-
compatible child seats. LATCH stands for
"Lower anchors and Tethers for Children".
These seats include two rigid or webbing
mounted attachments that connect to two
LATCH anchors at specific seating posi-
tions in your vehicle. This type of child seat
eliminates the need to use seat belts to
attach the child seat. LATCH anchors have
been provided in your vehicle. The LATCH
anchors are located in the left and right
outboard rear seating positions. Their loca-
tions are shown in the illustration. There is
no LATCH anchor provided for the center
rear seating position.

!
WARNING:
o A child can be seriously injured or
killed in a collision if the child restraint
is not properly anchored. Always
follow the child seat manufacturer’s
instructions for installation and use.
o Never install a child restraint using
the LATCH lower anchors at the cen-
ter position of the rear seat. In a
crash, the LATCH lower anchors may
break if a car seat is improperly placed
in the center position resulting in se-
rious or fatal injuries. Only place a
LATCH or LATCH-compatible child
seat in the left or right out-board rear
seating positions (as shown) to the
appropriate LATCH anchors pro-
vided.
o Never mount more than one child
restraint to a single tether or to a
single lower anchorage point. The
increased load caused by multiple
seats may cause the tethers or
anchorage points to break, causing
serious injury or death.

Follow the child seat manufacturer's in-
structions to properly install safety seats
with LATCH or LATCH-compatible attach-
ments.
Once you have installed the LATCH child
restraint seat, assure that the seat is
properly attached to the LATCH 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.
!
o When using the vehicle’s “LATCH”
system to install a child restraint sys-
tem in the rear seat, all unused ve-
hicle rear seat belt metal latch plates
or tabs must be latched securely in
their seat belt buckles and the seat
belt webbing must be retracted be-
hind the child restraint to prevent the
child from reaching and taking hold of
unretracted seat belts. Unlatched
metal latch plates or tabs may allow
the child to reach the unretracted
seat belts which may result in stran-
gulation and a serious injury or death
to the child in the child restraint.
WARNING:
WARNING:
A child can be seriously injured or killed
in a collision if the child restraint is not
properly anchored to the car and the
child is not properly restrained in the
child restraint. Always follow the child
seat manufacturer’s instructions for
installation and use.
!
CAUTION:
Do not allow the rear seat belt webbing to
get scratched or pinched by the child-
seat latch and LATCH anchor during the
installation.

On rear seat center positionTo 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:
o If the retractor is not in the Automatic
Locking mode, the child restraint can
move when your vehicle turns or stops
suddenly. A child can be seriously
injured or killed if the child restraint is
not properly anchored to the car,
including setting the retractor to the
Automatic Locking mode.
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
system in any seating position, read
the instructions supplied by the child
restraint system manufacturer.
o If the seat belt does not operate as
described, have the system checked
immediately by your authorized
Hyundai dealer.

WARNING:
To obtain maximum benefit from a pre-
tensioner seat belt:
o The seatbelt must be worn correctly and
adjusted to the proper position (see
pages 1-24 and 1-27). Please read and
follow all of the important information
and precautions about your vehicle’s
occupant safety features – including
seat belts and advanced airbags – that
are provided in this manual.
!
CAUTION:
Do not put anything near the buckle.
Placing objects near the buckle can ad-
versely 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
tension 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
locations are shown in the illustration:
B180B03NF-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-tensioner (which is
installed in the buckle) will also pull the
seat belt into the buckle.

!
o Be sure you and your passengers
always wear seat belts and wear them
properly.NOTE:o Both the driver's and front
passenger's pre-tensioner seat belts
will be activated in certain frontal col-
lisions. The pre-tensioner seat belts
can be activated alone or, where the
frontal collision is severe enough,
together with the airbags.
The pre-tensioners will not be
activated if the seat belts are not being
worn at the time of the collision.
o When the pre-tensioner seat belts are
activated, a loud noise may be heard
and fine dust, which may appear to be
smoke, may be visible in the
passenger compartment. These are
normal operating conditions and are
not hazardous.
o Although it is harmless, the fine dust
may cause skin irritation and should
not be breathed for prolonged periods.
Wash all exposed skin areas thor-
oughly after an accident in which the
pre-tensioner seat belts were acti-
vated.
WARNING:
!
CAUTION:
o Because the sensor that activates
the SRS airbag is connected with the
pre-tensioner seat belt, the SRS airbag
warning light
on the instrument
panel will illuminate for approximately
6 seconds after the ignition key has
been turned to the "ON" position, and
then it should turn off.
o If the pre-tensioner seat belt is not
working properly, this warning light
will illuminate even if there is no
malfunction of the SRS airbag. If the
SRS airbag warning light does not
illuminate when the ignition key is
turned to "ON", or if it blinks for a
second and remains illuminated after
illuminating for approximately 6 sec-
onds, or if it illuminates while the ve-
hicle is being driven, please have an
authorized Hyundai dealer inspect the
pre-tensioner seat belt or SRS airbag
system as soon as possible.
!
WARNING:
o Pre-tensioners are designed to oper-
ate only one time. After activation,
pre-tensioner seat belts must be re-
placed. All seat belts, of any type,
should always be replaced after they
have been worn during a collision.
o The pre-tensioner seat belt assembly
mechanisms become hot during acti-
vation. Do not touch the pre-tensioner
seat belt assemblies for several min-
utes after they have been activated.
o Do not attempt to inspect or replace
the pre-tensioner seat belts yourself.
This must be done by an authorized
Hyundai dealer.
o Do not strike the pre-tensioner seat
belt assemblies.
o Do not attempt to service or repair the
pre-tensioner seat belt system in any
manner.
o Improper handling of the pre-tensioner
seat belt assemblies, and failure to heed
the warnings not to strike, modify, in-
spect, replace, service or repair the
pre-tensioner seat belt assemblies may
lead to improper operation or inadvert-
ent activation and serious injury.
o Always wear the seat belts when driv-
ing or riding in a motor vehicle.
o If the vehicle or pre-tensioner seat
belt must be discarded, contact an
authorised Hyundai dealer.
