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
All 50 states 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 states,
so you should be aware of the specific
requirements in your state, 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 Federal Motor
Vehicle Safety Standards. Before buying
any child restraint system, make sure
that it has a label certifying that it meets
Federal Motor Vehicle Safety Standard
FMVSS 213. 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.
Seats & Safety System

3-29
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.
All 50 states 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 states, so you should be aware of
the specific requirements in your state,
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 Federal Motor
Vehicle Safety Standards (FMVSS 213).
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.

Selecting a Child Restraint
System (CRS)
When selecting a CRS for your child,
always:
• Make sure the CRS has a label
certifying that it meets applicable
Federal Motor Vehicle Safety
Standards (FMVSS 213).
• Select a child restraint based on
your child’s height and weight. The
required label or the instructions for
use typically provide this information.
• Select a child restraint 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 the child restraint
system.
Child restraint system types
There are three main types of child
restraint systems: rear-facing seats,
forward-facing seats, and booster seats.
They are classified according to the
child’s age, height and weight.
Rear-facing child seats
WARNING
NEVER install a child or infant restraint
in the front passenger’s seat.
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.
ODN8039027
A rear-facing child seat 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
seat and reduce the stress to the neck
and spinal cord.
All children under age one must always
ride in a rear-facing infant child restraint.
Convertible and 3-in-1 child seats
typically have higher height and weight
limits for the rear-facing position,
allowing you to keep your child rear-
facing for a longer period of time.
Continue to use a rear-facing child seat
for as long as your child will fit within the
height and weight limits allowed by the
child seat manufacturer. It’s the best way
to keep them safe. Once your child has
outgrown the rear-facing child restraint,
your child is ready for a forward-facing
child restraint with a harness.

ODN8039028
Forward-facing child restraints
A forward-facing child seat provides
restraint for the child’s body with a
harness. Keep children in a forward-
facing child seat with a harness until
they reach the top height or weight
limit allowed by your child restraint’s
manufacturer.
Once your child outgrows the forward-
facing child restraint, your child is ready
for a booster seat.
Booster seats
A booster seat is a restraint 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 the lap of
your child.
Keep your child in a booster seat until
they are big enough to sit in the seat
without a booster and still have the
seat belt fit properly. For a seat belt
to fit properly, the lap belt must lie
snugly across the upper thighs, not the
stomach. The shoulder belt should lie
snug across the shoulder and chest and
not across the neck or face. Children
under age 13 must always ride in the
rear seats and must always be properly
restrained to minimize the risk of injury.
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.
• Read and follow the instructions
regarding child restraint systems in
this manual.
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 seat as
described in the child seat system
manual, the head restraint of the
respective seating position shall be
readjusted or entirely removed.

3-34
NOTICE
The recommended weight for the
LATCH system is under 65 lb (30 kg).
How to determine an appropriate child
restraint weight:
Child weight + Child restraint weight <
65 lb (30kg)
Securing a child restraint seat with
“Tether Anchor” system
ODN8A039029
First secure the child restraint with
the LATCH lower anchors or the seat
belt. If the child restraint manufacturer
recommends that the top tether strap
be attached, attach and tighten the
top tether strap to the top tether strap
anchor.
Child restraint hook holders are located
on the rear of the seatbacks.
WARNING
Take the following precautions when
installing the tether strap:
• Read and follow all installation
instructions provided with your child
restraint system.
• NEVER attach more than one child
restraint to a single tether anchor.
This could cause the anchor or
attachment to come loose or break.
• Do not attach the tether strap to
anything other than the correct
tether anchor. It may not work
properly if attached to something
else.
• Do not use the tether anchors for
adult seat belts or harnesses, or for
attaching other items or equipment
to the vehicle.
ODN8039030
To install the tether anchor:
1.

R
oute the child restraint tether strap
over the child restraint seatback.
Route the tether strap under the
head restraint and between the head
restraint posts, or route the tether
strap over the top of the vehicle
seatback. Make sure the strap is not
twisted.
2.

Connect the t
ether strap hook to the
tether anchor, then tighten the tether
strap according to the child seat
manufacturer’s instructions to firmly
secure the child restraint to the seat.

Occupant Classification System
(OCS)
ODN8A039038
Your vehicle is equipped with an
Occupant Classification System (OCS) in
the front passenger’s seat.
Main components of the Occupant
Classification System
• A detection device located within the
front passenger seat cushion.
• Electronic system to determine
whether the passenger air bag
systems should be activated or
deactivated.
• An indicator light located on the
instrument panel which illuminates
the words “PASSENGER AIR BAG OFF”
indicating the front passenger air bag
system is deactivated.
• The instrument panel air bag indicator
light is interconnected with the OCS.
The OCS is designed to help detect
the presence of a properly-seated
front passenger and determine if the
passenger’s front air bag should be
enabled (may inflate) or not.
The purpose is to help reduce the risk
of injury or death from an inflating air
bag to certain front passenger seat
occupants, such as children, by requiring
the air bag to be automatically turned
OFF. For example, if a child restraint of the
type specified in the regulations is on the
seat, the occupant classification sensor
can detect it and cause the air bag to
turn OFF.
Front passenger seat adult occupants
who are properly seated and wearing the
seat belt properly, should not cause the
passenger air bag to be automatically
turned OFF. For small adults it may be
turned OFF, however, if the occupant
does not sit in the seat properly (for
example, by not sitting upright, by sitting
on the edge of the seat, or by otherwise
being out of position), this could cause
the sensor to turn the air bag OFF.
You will find the “PASSENGER AIR BAG
OFF” indicator on the center fascia
panel. This system detects the conditions
1-4 in the following table and activates or
deactivates the front passenger air bag
based on these conditions.
Always be sure that you and all vehicle
occupants are seated properly and
wearing the seat belt properly for the
most effective protection by the air bag
and the seat belt.
The OCS may not function properly if the
passenger takes actions which can affect
the classification system. These include:
•
Failing to sit in an upright position.
• Leaning against the door or center
console.
• Sitting towards the sides of the front
of the seat.
• Putting their legs on the dashboard or
resting them on other locations which
reduce the passenger weight on the
front seat.
• Wearing the seat belt improperly.
• Reclining the seatback.
• Wearing a thick cloth like ski wear or
hip protection wear.
• Putting an additional thick cushion on
the seat.
• Putting electrical devices (e.g.
notebook, satellite radio) on the seat
with inverter charging.

WARNING
Riding in an improper position or placing weight on the front passenger’s seat when
it is unoccupied by a passenger adversely affects the OCS. To reduce the risk of
serious injury or death:
OVQ036013NB
• NEVER put a heavy load in the front seat or seatback
pocket, or hang any items on the front passenger
seat.
OLMB033100
