Installing a Child Restraint
System (CRS)
WARNING
Before installing your Child Restraint
System always:
• Read and follow the instructions
provided by the manufacturer of the
Child Restraint System.
Failure to follow all warnings and
instructions could increase the risk of
the SERIOUS INJURY or DEATH if an
accident occurs.
WARNING
If the vehicle headrest prevents proper
installation of a Child Restraint System
(as described in the Child Restraint
System manual), the headrest of the
respective seating position shall be
readjusted or entirely removed.After selecting a proper Child Restraint
System and checking that the Child
Restraint System fits properly in the rear
of this vehicle, you are ready to install
the Child Restraint System according to
the manufacturer’s instruction. There are
three general steps in installing the Child
Restraint System properly:
• Properly secure the Child Restraint
System to the vehicle. All Child
Restraint Systems must be secured to
the vehicle with the lap belt or lap part
of a lap/shoulder belt or with the top-
tether and/or ISOFIX anchorage.
• Make sure the Child Restraint System
is firmly secured. After installing a
Child Restraint System to the vehicle,
push and pull the Child Restraint
System forward and from side-
to-side to verify that it is securely
attached to the vehicle seat. A Child
Restraint System secured with a seat
belt should be installed as firmly as
possible. However, some side-to-side
movement can be expected.
When installing a Child Restraint
System, adjust the vehicle seat (up
and down, forward and rearward)
so that your child fits in the Child
Restraint System in a comfortable
manner.
• Secure the child in the Child
Restraint System. Make sure the
child is properly strapped in the Child
Restraint System according to the
Child Restraint System manufacturer’s
instructions.
WARNING
A Child Restraint System 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
System.

ISOFIX anchorage and top-tether
anchorage (ISOFIX system) for
children (if equipped)
The ISOFIX system holds a Child
Restraint System during driving and in
an accident. This system is designed
to make installation of the Child
Restraint System easier and reduce
the possibility of improperly installing
your Child Restraint System. The ISOFIX
system uses anchors in the vehicle and
attachments on the Child Restraint
System. The ISOFIX system eliminates
the need to use seat belts to secure the
Child Restraint System to the rear seats.
ISOFIX anchors are metal bars built into
the vehicle. There are two lower anchors
for each ISOFIX seating position that will
accommodate a Child Restraint System
with lower attachments.
To use the ISOFIX system in your
vehicle, you must have a Child Restraint
System with ISOFIX attachments. (An
ISOFIX-Child Restraint System may only
be installed if it has vehicle-specific or
universal approval in accordance with
the requirements of ECE-R 44 or ECE-R
129.)
The Child Restraint System manufacturer
will provide you with instructions on how
to use the Child Restraint System with its
attachments for the lower anchorages.
OLM039035OLM039035
ISOFIX anchorages have been provided
in the left and right outboard rear
seating positions. Their locations are
shown in the illustration. There are no
ISOFIX anchorages provided for the
center rear seating position.
WARNING
Do not attempt to install a Child
Restraint System using ISOFIX
anchorages in the rear center
seating position. There are no ISOFIX
anchorages provided for this seat.
Using the outboard seat anchorages,
for the CRS installation on the rear
center seating position, can damage
the anchorages which may break or fail
in a collision resulting in serious injury
or death.

Safety system
OAI3039016OAI3039016
The ISOFIX anchorages symbols are
located on the left and right rear seat
cushions to identify the position of the
ISOFIX anchorages in your vehicle (see
arrows in illustration).
OAI3039017OAI3039017
Both rear outboard seats are equipped
with a pair of ISOFIX anchorages as well
as a corresponding top-tether anchorage
on the back side of the rear seats.
(Child Restraint Systems with universal
approval according to ECE-R44 or
ECE-R129 need to be fixed additionally
with a top-tether connected to the
corresponding top-tether anchorage
point on the back side of the rear seats.)
ISOFIX anchorages are located between
the seatback and the seat cushion of the
rear seat left and right outboard seating
positions.
Securing a Child Restraint System
with the “ISOFIX system”
To install a ISOFIX-compatible Child
Restraint System in either of the rear
outboard seating positions:
1. Move the seat belt buckle away from
the ISOFIX anchorages.
2. Move any other objects away from
the anchors that could prevent a
secure connection between the Child
Restraint System and the ISOFIX
anchorages.
3. Place the Child Restraint System on
the vehicle seat, then attach the seat
to the ISOFIX anchorages according to
the instructions provided by the Child
Restraint System manufacturer.
4. Follow the instructions of the Child
Restraint System’s manufacturer for
proper installation and connection
of the ISOFIX attachments on the
Child Restraint System to the ISOFIX
anchorages.
WARNING
Take the following precautions when
using the ISOFIX 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 System to a single
anchorage. This could cause the
anchor or attachment to come loose
or break.
• Always have the ISOFIX system
inspected by your dealer after an
accident. An accident can damage
the ISOFIX system and may not
properly secure the Child Restraint
System.
Securing a Child Restraint System
with “Top-tether anchorage”
system (if equipped)
OBI3030004OBI3030004
First, secure the Child Restraint System
with the ISOFIX anchorages or the
seat belt. If the Child Restraint System
manufacturer recommends the top-
tether to be attached, attach and
tighten the top-tether to the top-tether
anchorage. Top-tether anchorages are
located on the back of the rear seats.
WARNING
Take the following precautions when
installing the top-tether:
• Read and follow all installation
instructions provided with your Child
Restraint System.
• NEVER attach more than one Child
Restraint System to a single top-
tether anchorage. This could cause
the anchorage or attachment to
come loose or break.
• Do not attach the top-tether to
anything other than the correct top-
tether anchorage. It may not work
properly if attached to something
else.
• Child Restraint System anchorages
are designed to withstand only those
loads imposed by correctly fitted
Child Restraint Systems. Under no
circumstances are they to be used for
adult seat belts or harnesses or for
attaching other items or equipment
to the vehicle.

3. Buckle the seat belt and allow the
seat belt to take up any slack. 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
• In order for side impact and
curtain air bags to provide the best
protection, both front seat occupants
and both outboard rear occupants
should sit in an upright position with
the seat belts properly fastened.
Importantly, children should sit in a
proper child restraint system in the
rear seat.
• When children are seated in the rear
outboard seats, they must be seated
in the proper child restraint system.
Make sure to put the child restraint
system as far away from the door
side as possible, and secure the child
restraint system in a locked position.
• 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 the 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
passengers when they are seated
on seats equipped with side and/or
curtain air bags.
• Do not open or repair the side curtain
air bags.
• Never try to open or repair any
components of the side curtain air
bag system. We recommend that the
system be serviced by an authorized
HYUNDAI dealer.
Failure to follow the above mentioned
instructions can result in injury or death
to the vehicle occupants in an accident.Why didn’t my air bag go off in a
collision? (Inflation and non-inflation
conditions of the air bag)
There are many types of accidents
in which the air bag would not be
expected to provide additional
protection.
These include rear impacts, second
or third collisions in multiple impact
accidents, as well as low speed
impacts.
