Rear Seats
Folding the rear seat
The rear seatbacks can be folded to
facilitate carrying long items or to
increase the luggage capacity of the
vehicle.
WARNING
• Never allow passengers to sit on top
of the folded down seatback while
the vehicle is moving. This is not a
proper seating position and no seat
belts are available for use. This could
result in serious injury or death in
case of an accident or sudden stop.
• Objects carried on the folded down
seatback should not extend higher
than the top of the front seatbacks.
This could allow cargo to slide
forward and cause injury or damage
during sudden stops.
To fold down the rear seatback:
1. Set the front seatback to the upright
position and if necessary, slide the
front seat forward.

located in the trunk.
ODN8039064L
4. Fold the seatback toward the front of
the vehicle.
5. To use the rear seat, lift and pull the
seatback rearward. Pull the seatback
firmly until it clicks into place. Make
sure the seatback is locked in place.

WARNING
When returning the rear seatback from
a folded to an upright position, hold the
seatback and return it slowly. Ensure
that the seatback is completely locked
into its upright position by pushing on
the top of the seatback. In an accident
or sudden stop, an unlocked seatback
could allow cargo to move forward with
great force and enter the passenger
compartment, which could result in
serious injury or death.
WARNING
Do not place objects in the rear seats,
since they cannot be properly secured
and may hit vehicle occupants in a
collision causing serious injury or death.
WARNING
Make sure the vehicle is off, the shift
button is in P (Park), and the parking
brake is securely applied whenever
loading or unloading cargo. Failure
to take these steps may allow the
vehicle to move if the shift button
is inadvertently moved to another
position.
Armrest
ODN8039018
The armrest is located in the center of
the rear seat. Pull the armrest down from
the seatback to use it.
Head Restraints
The vehicle’s front and rear seats
have adjustable head restraints. The
head restraints provide comfort for
passengers, but more importantly they
are designed to help protect passengers
from whiplash and other neck and spinal
injuries during an accident, especially in
a rear impact collision.
WARNING
To reduce the risk of serious injury or
death in an accident, take the following
precautions when adjusting your head
restraints:
• Always properly adjust the head
restraints for all passengers BEFORE
starting the vehicle.
• NEVER let anyone ride in a seat
with the head restraints removed or
reversed.

Seat Warmers and Air Ventilation
Seats
Front seat warmers (if equipped)
Seat warmers are provided to warm the
seats during cold weather.
WARNING
The seat warmers can cause a SERIOUS
BURN, even at low temperatures and
especially if used for long periods of
time.
Passengers must be able to feel if the
seat is becoming too warm so they can
turn it off, if needed.
People who cannot detect temperature
change or pain to the skin should
use extreme caution, especially the
following types of passengers:
• Infants, children, elderly or disabled
persons, or hospital outpatients.
• People with sensitive skin or who
burn easily.
• Fatigued individuals.
• Intoxicated individuals.
• People taking medication that can
cause drowsiness or sleepiness.
WARNING
NEVER place anything on the seat
that insulates against heat when the
seat warmer is in operation, such as a
blanket or seat cushion. This may cause
the seat warmer to overheat, causing a
burn or damage to the seat.
NOTICE
To prevent damage to the seat warmers
and seats:
Never use a solvent such as paint
thinner, benzene, alcohol or gasoline to
clean the seats.
Do not place heavy or sharp objects on
seats equipped with seat warmers.
Do not change the seat cover. It
may damage the seat warmer or air
ventilation system.

SEAT BELTS
This section describes how to use the
seat belts properly. It also describes
some of the things to avoid 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,
but they are not a substitute. Most states
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:
• ALWAYS properly restrain children
under age 13 in the rear seats.
• NEVER allow children to ride in the
front passenger seat. If a child age 13
or older must be seated in the front
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.
• Always wear both the shoulder
portion and lap portion of the lap/
shoulder belt.
• 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 prevent the seat belt
adjusting devices from operating to
remove slack, or prevent 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 Belt Restraint System
WARNING
Improperly positioned seat belts may
increase the risk of serious injury
in an accident. Take the following
precautions when adjusting the seat
belt:
• Position the lap portion of the seat
belt as low as possible across your
hips, not on your waist, so that it fits
snugly.
• Position one arm under the shoulder
belt and the other over the belt, as
shown in the illustration.
• Always position the shoulder belt
anchor into the locked position at the
appropriate height.
• NEVER position the shoulder belt
across your neck or face.
Seat Belt-Driver’s 3-point system
with emergency locking retractor
OHI038140
To fasten your seat belt:
Pull the seat belt out of the retractor and
insert the metal tab (1) into the buckle
(2). There will be an audible “click” when
the tab locks into the buckle.
OHI038137
You should place the lap belt (1) portion
across your hips and the shoulder belt (2)
portion across your chest.
The seat belt automatically adjusts to the
proper length after the lap belt portion
is adjusted manually so that it fits snugly
around your hips. If you lean forward in
a slow, easy motion, the belt will extend
and move with you.
If there is a sudden stop or impact, the
belt will lock into position. It will also lock
if you try to lean forward too quickly.

03
3-23
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.
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.
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.
Rear center seat belt
ODN8039074L
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.

Pre-tensioner seat belt
(Driver and front passenger)
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.
