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 "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.
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.

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 ISOFIX anchors at the center
position of the rear seat. In a crash,
the ISOFIX anchors may break if a car
seat is improperly placed in the center
position resulting in serious or fatal
injuries. Only place a ISOFIX or ISOFIX-
compatible child seat in the left or
right out-board rear seating positions
(as shown) to the appropriate ISOFIX
anchors provided.
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 ISOFIX or ISOFIX-compatible
attachments.
Once you have installed the ISOFIX child
restraint 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.
!
o When using the vehicle’s “ISOFIX”
system to install a child restraint
system in the rear seat, all unused
vehicle rear seat belt metal latch
plates or tabs must be latched se-
curely in their seat belt buckles and
the seat belt webbing must be re-
tracted behind 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 strangulation 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 ISOFIX-
seat latch and ISOFIX 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 1-23 and 1-26). 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:
B180B02NF-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,
inspect, replace, service or repair the
pre-tensioner seat belt assemblies
may lead to improper operation or
inadvertent activation and serious
injury.
o Always wear the seat belts when driv-
ing or riding in a motor vehicle.

The SRS uses sensors to gather
information about the driver's and front
passenger's seat position, the driver's and
front passenger's seat belt usage and
impact severity.
The driver's and front passenger's seat
track position sensors, which are installed
on the seat track, determine if the seats are
fore or aft of a reference position. The seat
belt buckle sensors determine if the driver
and front passenger's seat belts are
fastened. These sensors provide the ability
to control the SRS deployment based on
how close the driver's seat is to the steering
wheel, how close the passenger's seat is
to the instrument panel, whether or not the
seat belts are fastened, and how severe
the impact is.
The advanced SRS offers the ability to
control the airbag inflation with two levels.
A first stage level is provided for moderate-
severity impacts. A second stage level is
provided for more severe impacts.
According to the impact severity, seating
position and seat belt usage, the
SRSCM(SRS Control Module) controls the
airbag inflation. Failure to properly wear
seat belts can increase the risk or severity
of injury in an accident.
CAUTION:
If a seat track position sensor or an
occupant classification system is not
working properly, the SRS airbag warning
light
on the instrument panel will
illuminate because the SRS airbag
warning light is connected with the seat
track position sensor and the occupant
classification system. If the SRS airbag
warning light does not illuminate when
the ignition key is turned to the "ON"
position, remains illuminated after
approximately 6 seconds when the igni-
tion key is turned to the "ON" position, or
if it illuminates while the vehicle is being
driven, have an authorized Hyundai
dealer inspect the advanced SRS airbag
system as soon as possible.
!
Additionally, your Hyundai is equipped
with an occupant classification system in
the front passenger's seat. The occupant
classification system detects the presence
of a passenger in the front passenger's
seat and will turn off the front passenger's
airbag under certain conditions. For more
detail, see "Occupant Classification
System" later in this section.
B240A03NF-AATDriver's and Passenger's Front
AirbagYour Hyundai is equipped with an
advanced Supplemental Restraint
(Airbag) System. The indications of the
system's presence are the letters "SRS
AIRBAG" embossed on the airbag pad
cover in the steering wheel and the
passenger's side front panel pad above
the glove box.
The Hyundai SRS consists of airbags
installed under the pad covers in the center
of the steering wheel and the passenger's
side front panel above the glove box. The
purpose of the SRS is to provide the
vehicle's driver and/or the front passenger
with additional protection than that offered
by the seat belt system alone in case of a
frontal impact of sufficient severity.Driver's Front Airbag
