Rear centre seat belt
(if equipped)
OAC3039044TU
When using the rear centre seat belt, the
buckle with the “CENTER” mark must be
used.
i Information
If you are not able to pull out the safety
belt from the retractor, firmly pull the
belt out and release it. After release, you
will be able to pull the belt out smoothly.
Pre-tensioner seat belt
(if equipped)
OLMB033039/H
[1] : Retractor pre-tensioner seat belt
Your vehicle is equipped with driver’s
and front passenger’s Pre-tensioner
Seat Belts (Retractor Pre-tensioner). The
purpose of the pre-tensioner is to make
sure the seat belts fit tightly against the
occupant’s body in certain frontal or
side collision(s). The pre-tensioner seat
belts may be activated in crashes where
the frontal or side collision(s) is severe
enough, together with the air bags.
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.
If the system senses excessive tension
on the driver or passenger’s seat
belt when the pre-tensioner system
activates, the load limiter inside the
retractor pre-tensioner will release some
of the pressure on the affected seat belt
(if equipped with load limiter).

03
CAUTION
The pre-tensioner will activate not only
in a frontal collision but also in a side
collision, if the vehicle is equipped with
a side or curtain air bag.
WARNING

[Always wear your seat belt and sit
properly in your seat.

[Do not use the seat belt if it is loose
or twisted. A loose or twisted seat
belt will not protect you properly in
an accident.

[Do not place anything near the
buckle. This may adversely affect
the buckle and cause it to function
improperly.

[Always replace your pre-tensioners
after activation or an accident.

[NEVER inspect, service, repair or
replace the pre-tensioners yourself.
We recommend that you have the
pre-tensioners inspected, serviced,
repaired or replaced by a HYUNDAI
authorised repairer.

[Do not hit the seat belt assemblies.
WARNING
Do not touch the pre-tensioner seat
belt assemblies for several minutes
after they have been activated. When
the pre-tensioner seat belt mechanism
deploys during a collision, the pre-
tensioner can become hot and can burn
you.
CAUTION
Body work on the front area of
the vehicle may damage the pre-
tensioner seat belt system. Therefore,
we recommend that the system be
serviced by a HYUNDAI authorised
repairer.

NOTICE
The sensor that activates the SRS
air bag is connected with the pre–
tensioner seat belts. The SRS air bag
warning light on the instrument panel
will illuminate for approximately 6
seconds after the ignition switch is
placed to the ON position, and then it
should turn off.
If the pre-tensioner is not working
properly, the warning light will
illuminate even if the SRS air bag is not
malfunctioning. If the warning light
does not illuminate, stays illuminated
or illuminates when the vehicle is
being driven, we recommend the pre-
tensioner seat belts and/or SRS air bags
be inspected by a HYUNDAI authorised
repairer as soon as possible.

03
NOTICE

[Pre-tensioner seat belts may be
activated in certain frontal or side
collisions.

[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.

[Although it is non-toxic, the fine
dust may cause skin irritation and
should not be breathed for prolonged
periods. Wash all exposed skin areas
thoroughly after an accident in which
the pre-tensioner seat belts were
activated.
Additional seat belt safety
precautions
Seat belt use during pregnancy
The seat belt should always be used
during pregnancy. The best way to
protect your unborn child is to protect
yourself by always wearing the seat belt.
Pregnant women should always wear
a lap-shoulder seat belt. Place the
shoulder belt across your chest, routed
between your breasts and away from
your neck. Place the lap belt below your
belly so that it fits SNUGLY across your
hips and pelvic bone, under the rounded
part of the belly.
WARNING
To reduce the risk of serious injury or
death to an unborn child during an
accident, pregnant women should
NEVER place the lap portion of the
seat belt above or over the area of the
abdomen where the unborn child is
located.

Safety system
Seat belt use and children
Infant and small children
Most countries have Child Restraint
Systems laws which require children
to travel in approved Child Restraint
Systems devices, including booster
seats. The age at which seat belts can be
used instead of Child Restraint Systems
differs among countries, so you should
be aware of the specific requirements
in your country, and where you are
travelling. Infant and Child Restraint
Systems must be properly placed and
installed in a rear seat. For more details,
refer to the “Child Restraint Systems” in
this chapter.
WARNING
ALWAYS properly restrain infants and
small children in a Child Restraint System
appropriate for the child’s height and
weight.
To reduce the risk of serious injury or
death to a child and other passengers,
NEVER hold a child in your lap or arms
when the vehicle is moving. The violent
forces created during an accident will
tear off the child from your arms and
throw the child against the interior of the
vehicle.
Small children are best protected from
injury in an accident when properly
restrained in the rear seat by a Child
Restraint System that meets the
requirements of the Safety Standards of
your country. Before buying any Child
Restraint System, make sure that it has
a label certifying that it meets Safety
Standard of your country. The restraint
must be appropriate for your child’s
height and weight. Check the label
on the Child Restraint System for this
information. Refer to “Child Restraint
Systems” in this chapter.
Larger children
Children under age 13 and who are too
large for a booster seat must always
occupy the rear seat and use the
available lap/shoulder belts. A seat belt
should lie across the upper thighs and
be snug across the shoulder and chest
to restrain the child safely. Check belt fit
periodically. A child’s squirming could
put the belt out of position. Children are
afforded the most safety in the event of
an accident when they are restrained by
a proper restraint system and/or seat
belts in the rear seat.
If a larger child over age 13 must be
seated in the front seat, the child must
be securely restrained by the available
lap/shoulder belt and the seat should be
placed in the rearmost position.
If the shoulder belt portion slightly
touches the child’s neck or face, try
placing the child closer to the centre
of the vehicle. If the shoulder belt still
touches their face or neck, they need to
be returned to an appropriate booster
seat in the rear seat.
WARNING

[Always make sure larger children’s
seat belts are worn and properly
adjusted.

[NEVER allow the shoulder belt to
contact the child’s neck or face.

[Do not allow more than one child to
use a single seat belt.

Seat belt use and injured people
A seat belt should be used when an
injured person is being transported.
Consult a physician for specific
recommendations.
One person per belt
Two people (including children) should
never attempt to use a single seat belt.
This could increase the severity of injuries
in case of an accident.
Do not lie down
Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the protections
of your restraint system (seat belts
and/or air bags) is greatly reduced by
reclining your seatback.
Seat belts must be snug against your
hips and chest to work properly. During
an accident, you could be twined with
the seat belt, causing neck or other
injuries.
The more the seatback is reclined,
the greater chance the passenger’s
hips will slide under the lap belt or the
passenger’s neck will strike the shoulder
belt.
WARNING

[NEVER ride with a reclined seatback
when the vehicle is moving.

[Riding with a reclined seatback
increases your chance of serious
or fatal injuries in the event of a
collision or sudden stop.

[Driver and passengers should always
sit well back in their seats, properly
belted, and with the seatbacks
upright.
Care of seat belts
Seat belt systems should never be
disassembled or modified. In addition,
care should be taken to assure that
seat belts and belt hardware are not
damaged by seat hinges, doors or other
abuse.
Periodic inspection
All seat belts should be inspected
periodically for wear or damage of any
kind. Any damaged parts should be
replaced as soon as possible.
Keep belts clean and dry
Seat belts should be kept clean and
dry. If belts become dirty, they can be
cleaned by using a mild soap solution
and warm water. Bleach, dye, strong
detergents or abrasives should not be
used because they may damage and
weaken the fabric.
When to replace seat belts
The entire seat belt assembly or
assemblies should be replaced if the
vehicle has been involved in an accident.
This should be done even if no damage
is visible. We recommend that you
consult a HYUNDAI authorised repairer.

Child Restraint System (CRS) always
in the rear
Infants and younger children must be
restrained in an appropriate rearward-
facing or forward-facing CRS that has
first been properly secured to the rear
seat of the vehicle. Read and comply
with the instructions for installation and
use provided by the manufacturer of the
Child Restraint System.
WARNING

[Always follow the Child Restraint
System manufacturer’s instructions
for installation and use.

[Always properly restrain your child in
the Child Restraint System.

[Do not use an infant carrier or a
child safety seat that “hooks” over
a seatback, it may not provide
adequate protection in an accident.

[After an accident, we recommend
a HYUNDAI dealer check the Child
Restraint System, seat belts,
ISOFIX anchorages and top-tether
anchorages.
Selecting a Child Restraint
System (CRS)
When selecting a CRS for your child,
always:

[Make sure a CRS has a label certifying
that it meets applicable Safety
Standards of your country.

[Select a CRS based on your child’s
height and weight. The required label
or the instructions for use typically
provide this information.

[Select a CRS that fits the vehicle
seating position where it will be used.

[Read and comply with the warnings
and instructions for installation and
use provided with a CRS.
Child Restraint System types
There are three main types of Child
Restraint Systems: rearward-facing
seats, forward-facing seats, and booster
seats. They are classified according to
the child’s age, height and weight.

3-32
Safety system
CRS09
Rearward-facing Child Restraint
System
A rearward-facing Child Restraint
System provides restraint with the
seating surface against the back of the
child. The harness system holds the
child in place, and in an accident, acts
to keep the child positioned in the Child
Restraint Systems and reduce the stress
to the fragile neck and spinal cord.
All children under the age of one
year must always ride in a rearward-
facing Child Restraint System. There
are different types of rearward-facing
Child Restraint Systems: infant-only
Child Restraint Systems can only be
used rearward-facing. Convertible
and 3-in-1 Child Restraint Systems
typically have higher height and weight
limits for the rearward-facing position
system, allowing you to keep your child
rearward-facing for a longer period of
time.
Keep using Child Restraint Systems in
the rearward-facing position as long as
children fit within the height and weight
limits allowed by the Child Restraint
System’s manufacturer.
OIB034017
Forward-facing Child Restraint
System
A forward-facing Child Restraint System
provides restraint for the child’s body
with a harness. Keep children in a
forward-facing Child Restraint System
with a harness until they reach the top
height or weight limit allowed by your
Child Restraint System’s manufacturer.
Once your child outgrows the forward-
facing Child Restraint System, your child
is ready for a booster seat.
Booster seats
A booster seat is Child Restraint System
designed to improve the fit of the
vehicle’s seat belt system. A booster
seat positions the seat belt so that it fits
properly over your child’s stronger body
parts. Keep your children in booster
seats until they are big enough to fit in a
seat belt properly.
For a seat belt to fit properly, the lap belt
must lie comfortable across the upper
thighs, not the stomach. The shoulder
belt should lie comfortable across the
shoulder and chest and not across the
neck or face. Children under age 13
must always be properly restrained to
minimise the risk of injury in an accident,
sudden stop or sudden manoeuvre.

03
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 head restraint prevents
proper installation of a Child Restraint
System, the head restraint 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 Systems 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 ISOFIX 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 seat forward and
from side-to-side to verify that it is
securely attached to the 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.
CAUTION
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.
