Seatback angle
To recline the seatback:
1. Lean forward slightly and lift up the seatback lever.
2. Carefully lean back on the seat and adjust the seatback to the position
you desire.
3. Release the lever and make sure the seatback is locked in place. (The lever
MUST return to its original position for
the seatback to lock.)
Reclining seatback
Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the protection of
your restraint system (seat belts and air
bags) is greatly reduced by reclining your
seatback.
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.
Drivers and passengers should ALWAYS
sit well back in their seats, properly
belted, and with the seatbacks upright. Seat belts must be snug against your
hips and chest to work properly. When
the seatback is reclined, the shoulder
belt cannot do its job because it will not
be snug against your chest. Instead,
it will be in front of you. During an
accident, you could be thrown into 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.
ODN8039004
Seat cushion height
To change the height of the seat cushion: •
Push down on the lever several times,
to lower the seat cushion.
• Pull up on the lever several times, to
raise the seat cushion.

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.

NOTICE
If you are not able to smoothly pull
enough of the seat belt out from the
retractor, firmly pull the seat belt out
and release it. After release, you will be
able to pull the belt out smoothly.
Height adjustment
You can adjust the height of the shoulder
belt anchor to one of the three different
positions for maximum comfort and
safety. The shoulder portion should be
adjusted so it lies across your chest and
midway over your shoulder nearest the
door, not over your neck. To adjust the
height of the seat belt anchor, lower
or raise the height adjuster into an
appropriate position.

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.

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 line so
that it fits snugly and as low as possible
across the hips, not across the abdomen.
WARNING
• A pregnant woman or a patient is
more vulnerable to any imapcts on
the abdomen during an abrupt stop
or accident. If you are in an accident
while pregnant, we recommend you
consult your doctor.
• 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
laws which require children to travel
in approved child restraint devices,
including booster seats. The age at
which seat belts can be used instead of
child restraints differs among countries,
so you should be aware of the specific
requirements in your country, and where
you are travelling.
Infant and child restraints must be
properly placed and installed in a rear
seat. For more information refer to the
“Child Restraint Systems” section in this
chapter.
WARNING
ALWAYS properly restrain infants
and small children in a child restraint
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
Standards of your country. The restraint
must be appropriate for your child’s
height and weight. Check the label on
the child restraint for this information.
Refer to the “Child Restraint Systems”
section in this chapter.

Children Always in the Rear
WARNING
Always properly restrain children in the
rear seats of the vehicle.
Children of all ages are safer when
restrained in the rear seat. A child riding
in the front passenger seat can be
forcefully struck by an inflating air bag
resulting in SERIOUS INJURY or DEATH.
Children under age 13 must always
ride in the rear seats and must always
be properly restrained to minimize the
risk of injury in an accident, sudden
stop or sudden maneuver. According
to accident statistics, children are safer
when properly restrained in the rear
seats than in the front seat. Even with
air bags, children can be seriously
injured or killed. Children too large for
a child restraint must use the seat belts
provided.
Most countries have child restraint
laws which require children to travel in
approved child restraint devices.
The laws governing the age or height/
weight restrictions at which seat belts
can be used instead of child restraints
differs among countries, so you should
be aware of the specific requirements
in your country, and where you are
travelling.
Child restraint systems must be properly
placed and installed in the rear seat.
You must use a commercially available
child restraint system that meets the
requirements of the Safety Standards of
your country.
Child restraint systems are generally
designed to be secured in a vehicle seat
by lap belt portion of a lap/shoulder belt,
or by a LATCH system in the rear seats of
the vehicle. Child restraint system (CRS)
Infants and younger children must be
restrained in an appropriate rear-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.
WARNING
An improperly secured child restraint
can increase the risk of SERIOUS
INJURY or DEATH in an accident. Always
take the following precautions when
using a child restraint system: • NEVER install a child or infant
restraint in the front passenger’s
seat.
• Always properly secure the child
restraint to a rear seat of the vehicle.
• Always follow the child restraint
system manufacturer’s instructions
for installation and use.
• Always properly restrain your child in
the child restraint.
• If the vehicle head restraint prevents
proper installation of a child seat
(as described in the child restraint
system manual), the head restraint of
the respective seating position shall
be readjusted or entirely removed.
• 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, have a HYUNDAI
dealer check the child restraint
system, seat belts, tether anchors
and lower anchors.
