Safety system of your vehicle
After selecting a proper child seat for
your child, check to make sure it fits
properly in your vehicle. Follow the
instructions provided by the manu-
facturer when installing the child
seat. Note these general steps when
installing the seat to your vehicle:

Properly secure the child restraint
to the vehicle.
All child restraints
must be secured to the vehicle with
the lap part of a lap/shoulder belt or
with the LATCH system.
Make sure the child restraint is
firmly secured. After installing a
child restraint to the vehicle, push
and pull the seat forward and from
side-to-side to verify that it is
securely attached to the seat. A
child restraint secured with a seat
belt should be installed as firmly as
possible. However, some side-to-
side movement can be expected.
Secure the child in the child
restraint. Make sure the child is
properly strapped in the child
restraint according to the manufac-
turer instructions.
Lower Anchors and Tether for Children (LATCH) System
The LATCH system holds a child
restraint during driving and in an
accident. This system is designed to
make installation of the child restraint
easier and reduce the possibility of
improperly installing your child
restraint. The LATCH system uses
anchors in the vehicle and attach-
ments on the child restraint. The
LATCH system eliminates the need
to use seat belts to secure the child
restraint to the rear seats.
Lower anchors are metal bars built
into the vehicle. There are two lower
anchors for each LATCH seating
position that will accommodate a
child restraint with lower attach-
ments.
To use the LATCH system in your
vehicle, you must have a child
restraint with LATCH attachments.
The child seat manufacturer will pro-
vide you with instructions on how to
use the child seat with its attach-
ments for the LATCH lower anchors.
A child restraint in a closed
vehicle can become very hot. To
prevent burns, check the seat-
ing surface and buckles before
placing your child in the child
restraint.
CAUTION

Safety system of your vehicle
Securing a child restraint withthe LATCH anchors system
To install a LATCH-compatible child
restraint in either of the rear outboard
seating positions:
1. Move the seat belt buckle away
from the lower anchors.
2. Move any other objects away from the anchors that could prevent a
secure connection between the
child restraint and the lower
anchors.
3. Place the child restraint on the vehicle seat, then attach the seat
to the lower anchors according to
the instructions provided by the
child restraint manufacturer.
4. Follow the child restraint instruc- tions for properly adjusting and
tightening the lower attachments
on the child restraint to the lower
anchors. The recommended weight for the
LATCH system is under 65 lb (30
kg).
How to calculate the child
restraint weight :
Child restraint weight =
65 lb (30 kg) - Child weight
NOTICE
Take the following precautions
when using the LATCH system:
Read and follow all installation
instructions provided with
your child restraint system.
To prevent the child from
reaching and taking hold of
unretracted seat belts, buckle
all unused rear seat belts and
retract the seat belt webbing
behind the child. Children can
be strangled if a shoulder belt
becomes wrapped around
their neck and the seat belt
tightens.
NEVER attach more than one
child restraint to a single
anchor. This could cause the
anchor or attachment to come
loose or break.
Always have the LATCH sys-
tem inspected by your author-
ized HYUNDAI dealer after an
accident. An accident can
damage the LATCH system
and may not properly secure
the child restraint.

Securing a child restraint seatwith "Tether Anchor" system
First secure the child restraint with
the LATCH lower anchors or the seat
belt. If the child restraint manufactur-
er recommends that the top tether
strap be attached, attach and tighten
the top tether strap to the top tether
strap anchor.
Child restraint hook holders are
located on the package tray. To install the tether anchor:
1. Route the child restraint tether strap
over the child restraint seatback.
Route the tether strap under the
head restraint and between the
head restraint posts, or route the
tether strap over the top of the vehi-
cle seatback. Make sure the strap is
not twisted.
2. Connect the tether strap hook to the tether anchor, then tighten the teth-
er strap according to the child seat
manufacturer's instructions to firmly
secure the child restraint to the seat.
3. Check that the child restraint is securely attached to the seat by
pushing and pulling the seat forward
and from side-to-side.
Take the following precautions
when installing the tether strap:
Read and follow all installation
instructions provided with
your child restraint system.
NEVER attach more than one
child restraint to a single teth-
er anchor. This could cause
the anchor or attachment to
come loose or break.
Do not attach the tether strap
to anything other than the cor-
rect tether anchor. It may not
work properly if attached to
something else.
Do not use the tether anchors
for adult seat belts or harness-
es, or for attaching other items
or equipment to the vehicle.

Securing a child restraint witha lap belt or lap/shoulder belt
When not using the LATCH system,
all child restraints must be secured to
a vehicle rear seat with the lap part
of a lap/shoulder belt.
Automatic locking mode
Since all passenger seat belts move
freely under normal conditions and
only lock under extreme or emer-
gency conditions (emergency locking
mode), you must manually pull the
seat belt all the way out to shift the
retractor to the "Automatic Locking"
mode to secure a child restraint.
The "Automatic Locking" mode will
help prevent the normal movement
of the child in the vehicle from caus-
ing the seat belt to loosen and com-
promise the child restraint system. To
secure a child restraint system, use
the following procedure. To install a child restraint system on
the rear seats, do the following:
1. Place the child restraint system on
a rear seat and route the lap/
shoulder belt around or through
the child restraint, following the
restraint manufacturer's instruc-
tions.
Be sure the seat belt webbing is
not twisted.
When using the rear center seat
belt, you should also refer to the
"3-point Rear Center Seat Belt"
section in this chapter.
NOTICE
ALWAYS place a rear-facing
child restraint in the rear seat of
the vehicle.
Placing a rear-facing child
restraint in the front seat can
result in serious injury or death
if the child restraint is struck by
an inflating air bag.

Curtain air bags
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors.They are designed to help protect the
heads of the front seat occupants
and the rear outboard seat occupants
in certain side impact collisions.
The curtain air bags are designed to
deploy only during certain side
impact collisions, depending on the
crash severity, angle, speed and
impact.
The side and curtain air bags on
both sides of the vehicle may deploy
if a rollover or possible rollover is
detected.
The curtain air bags are not designed
to deploy in all side impact or rollover
situations.
To reduce the risk of serious
injury or death from an inflating
curtain air bags, take the follow-
ing precautions:All seat occupants must wear
seat belts at all times to help
keep occupants positioned
properly. (Continued)

the air bag. Also, do not attach
any objects around the area the
air bag inflates such as the
door, side door glass, front and
rear pillar, roof side rail.
Do not hang other objects
except clothes, especially
hard or breakable objects. In
an accident, it may cause vehi-
cle damage or personal injury.
