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
manufacturer 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-back
and 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 manufacturer
instructions.
CAUTION
A child restraint in a closed vehicle can
become very hot. To prevent burns,
check the seating surface and buckles
before placing your child in the child
restraint.
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
attachments 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 attachments.
To use the LATCH system in your vehicle,
you must have a child restraint with
LATCH attachments.
The child seat manufacturer will provide
you with instructions on how to use the
child seat with its attachments for the
LATCH lower anchors.
ODN8039075L
LATCH anchors have been provided in
the left and right outboard rear seating
positions. Their locations are shown
in the illustration. There are no LATCH
anchors provided for the center rear
seating position.

WARNING
Do not attempt to install a child
restraint system using LATCH anchors in
the rear center seating position. There
are no LATCH anchors provided for this
seat. Using the outboard seat anchors
can damage the anchors which may
break or fail in a collision resulting in
serious injury or death.
ODN8A039031[A]: ISOFIX Anchorage Position Indicator,
[B]: ISOFIX Anchorage
The lower anchor position indicator
symbols are located on the left and right
rear seat backs to identify the position
of the lower anchors in your vehicle (see
arrows in illustration).
The LATCH anchors are located between
the seatback and the seat cushion of the
rear seat left and right outboard seating
positions.
Securing a child restraint with the
LATCH anchors system
To install a LATCH-compatible child
restraint in either of the rear outboard
seating positions:
1.
M
ove the seat belt buckle away from
the lower anchors.
2.

M
ove 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 r
estraint on the vehicle
seat, then attach the seat to the lower
anchors according to the instructions
provided by the child restraint
manufacturer.
4.
F

ollow the child restraint instructions
for properly adjusting and tightening
the lower attachments on the child
restraint to the lower anchors.
WARNING
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 system
inspected by your authorized
HYUNDAI dealer after an accident.
An accident can damage the LATCH
system and may not properly secure
the child restraint.

Securing a child restraint seat with
“Tether Anchor” system
ODN8A039029
First secure the child restraint with
the LATCH lower anchors or the seat
belt. If the child restraint manufacturer
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 rear of the seatbacks.
WARNING
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 tether anchor.
This could cause the anchor or
attachment to come loose or break.
• Do not attach the tether strap to
anything other than the correct
tether anchor. It may not work
properly if attached to something
else.
• Do not use the tether anchors for
adult seat belts or harnesses, or for
attaching other items or equipment
to the vehicle.
ODN8039030
To install the tether anchor:
1.

R
oute 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 vehicle
seatback. Make sure the strap is not
twisted.
2.

Connect the t
ether strap hook to the
tether anchor, then tighten the tether
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-back and side-to-side.
Securing a child restraint with 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.
WARNING
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.

Automatic locking mode
Since all passenger seat belts move
freely under normal conditions and
only lock under extreme or emergency
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 causing
the seat belt to loosen and compromise
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 r
estraint system on a
rear seat and route the lap/ shoulder
belt around or through the child
restraint, following the restraint
manufacturer’s instructions. Be sure
the seat belt webbing is not twisted.
Information
When using the rear center seat belt, you
should also refer to the “Rear Seat Belt –
Passenger’s 3-point system” section in this
chapter.

Information
Position the release button so that it is easy
to access in case of an emergency.
OLF034076
3. Pull the shoulder portion of the
seat belt all the way out. When the
shoulder portion of the seat belt
is fully extended, it will shift the
retractor to the “Automatic Locking”
(child restraint) mode.
OLF034075
4. Slowly allow the shoulder portion of the seat belt to retract and listen for
an audible “clicking” or “ratcheting”
sound. This indicates that the retractor
is in the “Automatic Locking” mode.
If no distinct sound is heard, repeat
steps 3 and 4. 5.

R
emove as much slack from the belt
as possible by pushing down on the
child restraint system while feeding
the shoulder belt back into the
retractor.
6.
Push and pull on the child r
estraint
system to confirm that the seat belt
is holding it firmly in place. If it is not,
release the seat belt and repeat steps
2 through 6.
7.
Double check tha
t the retractor is in
the “Automatic Locking” mode by
attempting to pull more of the seat
belt out of the retractor. If you cannot,
the retractor is in the “Automatic
Locking” mode.
If your CRS (child restraint system)
manufacturer instructs or recommends
you to use a tether anchor with the lap/
shoulder belt, refer to the previous pages
for more information.
Information
When the seat belt is allowed to retract to
its fully stowed position, the retractor will
automatically switch from the “Automatic
Locking” mode to the emergency lock
mode for normal adult usage.
WARNING
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 in the car,
including manually pulling the seat belt
all the way out to shift the rectractor to
the “Automatic Locking” mode.
To remove the child restraint, press the
release button on the buckle and then
pull the lap/shoulder belt out of the
restraint and allow the seat belt to retract
fully.
Seats & Safety System

3-38
This vehicle is equipped with an Advanced Supplemental Air Bag System for the
driver’s seat and front passenger’s seats.
The front air bags are designed to supplement the three-point seat belts. For these air
bags to provide protection, the seat belts must be worn at all times when driving.
You can be severely injured or killed in an accident if you are not wearing a seat belt.
Air bags are designed to supplement seat belts, but do not replace them. Also, air bags
are not designed to deploy in every collision. In some accidents, the seat belts are the
only restraint protecting you.
WARNING
AIR BAG SAFETY PRECAUTIONS
ALWAYS use seat belts and child restraints - every trip, every time, everyone! Even
with air bags, you can be seriously injured or killed in a collision if you are improperly
belted or not wearing your seat belt when the air bag inflates.
NEVER place a child in any child restraint or booster seat in the front passenger seat.
An inflating air bag could forcefully strike the infant or child causing serious or fatal
injuries.
ABC - Always Buckle Children under age 13 in the back seat. It is the safest place
for children of any age to ride. If a child age 13 or older must be seated in the front
seat, he or she must be properly belted and the seat should be moved as far back as
possible.
All occupants should sit 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 until the vehicle is parked and is turned off. If an occupant is out of
position during an accident, the rapidly deploying air bag may forcefully contact the
occupant causing serious or fatal injuries.
You and your passengers should never sit or lean unnecessarily close to the air bags
or lean against the door or center console.
Move your seat as far back as possible from front air bags, while still maintaining
control of the vehicle. The U.S. National Highway Traffic Safety Administration
(NHTSA) recommends that drivers allow at least 10 inches (25 cm) between the
center of the steering wheel and the chest.

WARNING
To reduce the risk of serious injury or
death from an inflating curtain air bag,
take the following precautions:
• All seat occupants must wear
seat belts at all times to help keep
occupants positioned properly.
• Properly secure child restraints as far
away from the door as possible.
• Do not place any objects over 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
vehicle damage or personal injury.
• Do not allow passengers to lean their
heads or bodies onto doors, put their
arms on the doors, stretch their arms
out of the window, or place objects
between the doors and seats.
• Do not open or repair the side curtain
air bags.

• In addition to inflating in certain side
collisions, vehicles equipped with a
rollover sensor, side and curtain air
bags will inflate if the sensing system
detects a rollover.
When a rollover is detected, side and
curtain air bags will remain inflated
longer to help provide protection
from ejection, especially when used in
conjunction with the seat belts.
• To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which
to inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises and
broken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
• There are even circumstances under
which contact with the air bag can
cause fatal injuries, especially if the
occupant is positioned excessively
close to the air bag.
You can take steps to help reduce the
risk of being injured by an inflating air
bag. The greatest risk is sitting too close
to the air bag. An air bag needs about 10
inches (25 cm) of space to inflate. NHTSA
recommends that drivers allow at least
10 inches (25 cm) between the center of
the steering wheel and the chest. WARNING
To reduce the risk of serious injury or
death from an inflating air bag, take the
following precautions:
• NEVER place a child restraint in the
front passenger seat.
Always properly restrain children
under age 13 in the rear seats of the
vehicle.
• Adjust the front passenger’s and
driver’s seats as far to the rear as
possible while allowing you to
maintain full control of the vehicle.
• Hold the steering wheel with
hands at the 9 o’clock and 3 o’clock
positions.
• NEVER place anything or anyone
between the air bag and the seat
occupant.
• Do not allow the front passenger
to place their feet or legs on the
dashboard.

Occupant Classification System
(OCS)
ODN8A039038
Your vehicle is equipped with an
Occupant Classification System (OCS) in
the front passenger’s seat.
Main components of the Occupant
Classification System
• A detection device located within the
front passenger seat cushion.
• Electronic system to determine
whether the passenger air bag
systems should be activated or
deactivated.
• An indicator light located on the
instrument panel which illuminates
the words “PASSENGER AIR BAG OFF”
indicating the front passenger air bag
system is deactivated.
• The instrument panel air bag indicator
light is interconnected with the OCS.
The OCS is designed to help detect
the presence of a properly-seated
front passenger and determine if the
passenger’s front air bag should be
enabled (may inflate) or not.
The purpose is to help reduce the risk
of injury or death from an inflating air
bag to certain front passenger seat
occupants, such as children, by requiring
the air bag to be automatically turned
OFF. For example, if a child restraint of the
type specified in the regulations is on the
seat, the occupant classification sensor
can detect it and cause the air bag to
turn OFF.
Front passenger seat adult occupants
who are properly seated and wearing the
seat belt properly, should not cause the
passenger air bag to be automatically
turned OFF. For small adults it may be
turned OFF, however, if the occupant
does not sit in the seat properly (for
example, by not sitting upright, by sitting
on the edge of the seat, or by otherwise
being out of position), this could cause
the sensor to turn the air bag OFF.
You will find the “PASSENGER AIR BAG
OFF” indicator on the center fascia
panel. This system detects the conditions
1-4 in the following table and activates or
deactivates the front passenger air bag
based on these conditions.
Always be sure that you and all vehicle
occupants are seated properly and
wearing the seat belt properly for the
most effective protection by the air bag
and the seat belt.
The OCS may not function properly if the
passenger takes actions which can affect
the classification system. These include:
•
Failing to sit in an upright position.
• Leaning against the door or center
console.
• Sitting towards the sides of the front
of the seat.
• Putting their legs on the dashboard or
resting them on other locations which
reduce the passenger weight on the
front seat.
• Wearing the seat belt improperly.
• Reclining the seatback.
• Wearing a thick cloth like ski wear or
hip protection wear.
• Putting an additional thick cushion on
the seat.
• Putting electrical devices (e.g.
notebook, satellite radio) on the seat
with inverter charging.
