Seats & Safety System3-24
This section describes how to use the
seat belts properly. It also describes
some of the things not to do when using
seat belts.
Seat belt safety precautions
Always fasten your seat belt and make
sure all passengers have fastened their
seat belts before starting any trip. Air
bags are designed to supplement the
seat belt as an additional safety device,
not a replacement. Most countries
require all occupants of a vehicle to wear
seat belts.
WARNING
Seat belts must be used by ALL
passengers whenever the vehicle is
moving. Take the following precautions
when adjusting and wearing seat belts:
• Children under the age of 13 should
be properly restrained in the rear
seats.
• Never allow children to ride in the
front passenger seat, unless the air
bag is deactivated. If a child is seated
in the front passenger seat, move
the seat as far back as possible and
properly restrain them in the seat.
• NEVER allow an infant or child to be
carried on an occupant’s lap.
• NEVER ride with the seatback
reclined when the vehicle is moving.
• Do not allow children to share a seat
or seat belt.
• Do not wear the shoulder belt under
your arm or behind your back. •
NEVER wear a seat belt over fragile
objects. If there is a sudden stop or
impact, the seat belt can damage it.
• Do not use the seat belt if it is
twisted. A twisted seat belt will not
protect you properly in an accident.
• Do not use a seat belt if the webbing
or hardware is damaged.
• Do not latch the seat belt into the
buckles of other seats.
• NEVER unfasten the seat belt
while driving. This may cause loss
of vehicle control resulting in an
accident.
• Make sure there is nothing in the
buckle interfering with the seat belt
latch mechanism. This may prevent
the seat belt from fastening securely.
• No modifications or additions
should be made by the user which
will either prohibit the seat belt
adjusting devices from operating to
remove slack, or prohibit the seat
belt assembly from being adjusted to
remove slack.
WARNING
Damaged seat belts and seat belt
assemblies will not operate properly.
Always replace:
• Frayed, contaminated, or damaged
webbing.
• Damaged hardware.
• The entire seat belt assembly after it
has been worn in an accident, even
if damage to webbing or assembly is
not apparent.
SEAT BELTS

Seats & Safety System
3-28
Rear Seat Belt – Passenger’s 3point
system with convertible locking
retractor
This type of seat belt combines the
features of both an emergency locking
retractor seat belt and an automatic
locking retractor seat belt. Convertible
retractor type seat belts are installed
in the rear seat positions to help
accommodate the installation of child
restraint systems. Although a convertible
retractor is also installed in the front
passenger seat position, NEVER place
any infant/child restraint system in the
front seat of the vehicle.
To fasten your seat belt:
Pull the seat belt out of the retractor
and insert the metal tab into the buckle.
There will be an audible “click” when
the tab locks into the buckle. When
not securing a child restraint, the seat
belt operates in the same way as the
driver’s seat belt (Emergency Locking
Retractor Type). It automatically adjusts
to the proper length only after the lap
belt portion of the seat belt is adjusted
manually so that it fits snugly across your
hips.
When the seat belt is fully extended from
the retractor to allow the installation of
a child restraint system, the seat belt
operation changes to allow the belt to
retract, but not to extend (Automatic
Locking Retractor Type). Refer to the
“Using a Child Restraint System” section
in this chapter.
OHI038142
To release your seat belt:
Press the release button (1) in the locking
buckle.
When it is released, the belt should
automatically draw back into the
retractor. If this does not happen, check
the belt to be sure it is not twisted, then
try again.
NOTICE
Although the seat belt retractor provides
the same level of protection for seated
passengers in either emergency
or automatic locking modes, the
emergency locking mode allows seated
passengers to move freely in their seat
while keeping some tension on the belt.
During a collision or sudden stop, the
retractor automatically locks the belt to
help restrain your body.
To deactivate the automatic locking
mode, unbuckle the seat belt and allow
the belt to fully retract.

Pre-tensioner seat belt (for driver’s
seat)
ONX4030071N
Your vehicle is equipped with driver’s
Pre-tensioner Seat Belts(Retractor
Pretensioner and Emergency Fastening
Device System). 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
Emergency Fastening Device System
may be activated in certain crashes
where the frontal 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 or
side collision(s), the pre-tensioner will
activate and pull the seat belt into tighter
contact against the occupant’s body.
(1) Retractor Pretensioner
The purpose of the retractor pre-
tensioner is to make sure that the
shoulder belts fit in tightly against the
occupant’s upper body in certain frontal
or side collision(s).
(2) Emergency Fastening Device System
The purpose of the Emergency Fastening
Device System is to make sure that
the pelvis belts fit in tightly against the
occupant’s lower body in certain frontal
collision(s).
If the system senses excessive tension
on the driver’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.

3-31
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 an
authorized HYUNDAI dealer.
• 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 the system to be serviced
by an authorized HYUNDAI dealer.
OLMB033040
The Pre-Tensioner Seat Belt System consists mainly of the following
components. Their locations are shown
in the illustration above:
(1) SRS air bag warning light
(2) Retractor pre-tensioner
(3) SRS control module
(4) Emergency fastening device

Seats & Safety System
3-32
NOTICE
The sensor that activates the SRS
control module is connected with the
pre–tensioner seat belts. The SRS air
bag warning light on the instrument
cluster will illuminate for approximately
3~6 seconds after the Engine Start/Stop
button is in 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 control
module be inspected by an authorized
HYUNDAI dealer as soon as possible.
Information
• Pre-tensioner seat belts may be
activated in certain frontal or side
collisions or rollover situations (if
equipped with rollover sensor).
• 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 inhaled 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.
Seat belt use and children
Infant and small children
Most countries have Child Restraint
System laws which require children to
travel in approved Child Restraint System
devices, including booster seats. The age
at which seat belts can be used instead
of Child Restraint System differs among
countries, so you should be aware of the
specific requirements in your country,
and where you are travelling. Infant and
Child Restraint System must be properly
placed and installed in a rear seat.
For more information refer to the “Child
Restraint Systems” section in this
chapter.

03
3-33
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 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 Child Restraint System 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”
section in this chapter.Larger children
Children under age 13 and who are
too large for a booster seat should
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. In the event
of an accident, children are afforded the
best safety restrained by a proper Child
Restraint System in the rear seats.
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 center
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.

Seats & Safety System
3-34
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 thrown
into the seat belt, causing neck or other
injuries.
The more the seat back is reclined, the
greater the chance for the passenger’s
hips to slide under the lap belt or the
passenger’s neck to 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
an authorized HYUNDAI dealer.
