Rear Seat Belt – Passenger’s 3-point
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 me
tal 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.
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.

Rear center seat belt
ODN8039074LODN8039074L
When using the rear center seat belt, the
buckle with the “CENTER” mark must be
used.
WARNING
Make sure that the seatback is locked in
place when using the rear center seat
belt.
If not, the seatback may move when
there is a sudden stop or collision,
which could result in serious injury.

Seats & Safety System3-24
Pre-tensioner seat belt
(Driver and front passenger)
OHI038143L OHI038143L
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).
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.
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.
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.
This must be done 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-
tensioners become hot and can burn
you.

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.
OHI038145OHI038145
Automatic locking mode
Since all passenger seat belts move
fr
eely 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 restraint 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.
OHI038146OHI038146
2. Fasten the lap/shoulder belt latch into the buckle. Listen for the distinct
“click” sound.

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.
OLF034075OLF034075
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. Remove 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 restraint 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 that 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.

WARNING
To reduce the risk of serious injury or
death from an inflating side air bag,
take the following precautions:
• Seat belts must be worn at all times
to help keep occupants positioned
properly.
• 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.
• Hold the steering wheel at the 9
o’clock and 3 o’clock positions, to
minimize the risk of injuries to your
hands and arms.
• Do not use any accessory seat
covers. This could reduce or prevent
the effectiveness of the system.
• Do not place any objects over the
air bag or between the air bag and
yourself. Also, do not attach any
objects around the area the air bag
inflates such as the door, side door
glass, front and rear pillar.
• Do not place any objects between
the door and the seat. They may
become dangerous projectiles if the
side air bag inflates.
• Do not install any accessories on the
side or near the side air bags.
• Do not put any objects between the
side airbag label and seat cushion. It
could cause harm if the vehicle is in a
crash severe enough to cause the air
bags to deploy.
• Do not cause impact to the doors
when the ignition switch button is in
the ON position as this may cause the
side air bags to inflate.
• If the seat or seat cover is damaged,
have the vehicle checked and
repaired by an authorized HYUNDAI
dealer.
Curtain air bags
ODN8039042ODN8039042
ODN8039043ODN8039043
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 during certain side impact
collisions, depending on the crash
severity.
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.

Seats & Safety System3-44
• 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.

Seats & Safety System
Do Not Install a Child Restraint in the
Front Passenger’s Seat
OHI039193NOHI039193N
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING
•
NEVER place a rear-facing or front-
facing child restraint in the front
passenger’s seat of the vehicle.
• An inflating frontal air bag could
forcefully strike a child resulting in
serious injury or death.
• Always properly restrain children in
an appropriate child restraint in the
rear seat of the vehicle.
Why Didn’t My Air Bag Go Off in
a Collision?
Air bags are not designed to inflate in
every collision. There are certain 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. Damage to the vehicle indicates
a collision energy absorption, and is not
an indicator of whether or not an air bag
should have inflated.
WARNING
To reduce the risk of an air bag
deploying unexpectedly and causing
serious injury or death:
• Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.
• Do not perform maintenance on or
around the air bag sensors. If the
location or angle of the sensors is
altered, the air bags may deploy
when they should not or may not
deploy when they should.
• Do not install bumper guards or
replace the bumper with a non-
genuine HYUNDAI parts. This may
adversely affect the collision and air
bag deployment performance.
• Place the ignition switch in the
LOCK/OFF or ACC position when the
vehicle is being towed to prevent
inadvertent air bag deployment.
• Have all air bag repairs conducted by
an authorized HYUNDAI dealer.
