This section describes how to use the
seat belts properly. It also describessome 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 fas-
tened their seat belts before starting
any trip. Air bags are designed tosupplement the seat belt as an addi-
tional safety device, but they are not
a substitute. Most countries require
all occupants of a vehicle to wear
seat belts.
SSEE AA TT BB EELLTT SS
Seat belts must be used by ALL
passengers whenever the vehi-
cle is moving. Take the followingprecautions when adjusting andwearing seat belts:
ALWAYS properly restrain
children under age 13 in therear seats.
(Continued)
WARNING
(Continued)
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 possi-
ble and properly restrain themin the seat.
NEVER allow an infant or child
to be carried on an occupant’slap.
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 shoul-
der portion and lap portion ofthe lap/shoulder belt.
Do not use the seat belt if it is
twisted. A twisted seat belt
will not protect you properlyin an accident.
(Continued)
(Continued)
Do not use a seat belt if the
webbing or hardware is dam-
aged.
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 result-ing 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.

Release the button to lock the
anchor into position. Try sliding the
height adjuster to make sure that it
has locked into 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 inthe rear seat positions to help accom-modate the installation of child
restraint systems. Although a convert-
ible retractor is also installed in thefront 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 buck-
le. 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 automati-cally 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 installa-
tion 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.

Larger children
Children under age 13 and who are
too large for a booster seat must
always occupy the rear seat and use
the available lap/shoulder belts. Aseat belt should lie across the upper
thighs and be snug across the shoul-
der and chest to restrain the child
safely. Check belt fit periodically.
Children are afforded the most safe-
ty in the event of an accident when
they are restrained by a proper
restraint system and/or seat belts in
the rear seat. Always have the
LATCH system inspected by your
authorized HYUNDAI dealer after an
accident. An accident can damage
the LATCH system and may not
properly secure the child restraint.
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 theseat should be placed in the rear-most position.If the shoulder belt portion slightly
touches the child's neck or face, tryplacing 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 appropriatebooster seat in the rear seat.
Transporting an injured person
A seat belt should be used when an
injured person is being transported.
Consult a physician for specific rec-
ommendations.
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 protec-
tions of your restraint system (seat
belts and air bags) is greatly reduced
by reclining your seatback.
To reduce the chance of injuries in the
event of an accident and to achieve
the maximum effectiveness of the
restraint system, all passengersshould be sitting up and the front and
rear seats should be in an upright
position when the car is moving.
Always make sure children are wearing their seat belts
and that they are properly
adjusted before driving.
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.

Children Always in the Rear
Children under age 13 must always
ride in the rear seats and must
always be properly restrained to min-
imize the risk of injury in an accident,
sudden stop or sudden maneuver.
According to accident statistics, chil-
dren are safer when properly
restrained in the rear seats than inthe front seat.Even with air bags,
children can be seriously injuredor 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 whichseat belts can be used instead of
child restraints differs among coun-
tries, so you should be aware of the
specific requirements in your coun-
try, and where you are travelling.
Child restraint systems must be
properly placed and installed in the
rear seat. You must use a commer-
cially available child restraint systemthat 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 sys-
tem in the rear seats of the vehicle.
Child restraint system (CRS)
Infants and younger children must be
restrained in an appropriate rear-fac-
ing 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.

Always properly restrain chil- dren 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 pas-
senger seat can be forcefully
struck by an inflating air bag
resulting in SERIOUS INJURY
or DEATH.
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 passen-
ger's seat.
Always properly secure the
child restraint to a rear seat of
the vehicle.

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 snug-
ly 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)After selecting a proper child seat for
your child, check to make sure it fits
properly in your vehicle. Follow the
instructions provided by the manu-
facturer when installing the child
seat. Note these general steps when
installing the seat to your vehicle:
Properly secure the child restraint
to the vehicle.
All child restraints
must be secured to the vehicle with
the lap part of a lap/shoulder belt or
with the LATCH system.
Make sure the child restraint is
firmly secured. After installing a
child restraint to the vehicle, push
and pull the seat forward-and-back
and side-to-side to verify that it is
securely attached to the seat. A
child restraint secured with a seat
belt should be installed as firmly as
possible. However, some side-to-
side movement can be expected.
Secure the child in the childrestraint. Make sure the child is
properly strapped in the child
restraint according to the manufac-
turer instructions.
Before installing your child
restraint system always:Read and follow the instruc-
tions provided by the manu-
facturer of the child restraint.
Read and follow the instruc-
tions regarding child restraint
systems in this manual.
Failure to follow all warningsand instructions could increase
the risk of the SERIOUS INJURY
or DEATH if an accident occurs.
WARNING
If the vehicle headrest prevents
proper installation of a child
seat (as described in the child
seat system manual, the head-rest of the respective seatingposition shall be readjusted or
entirely removed.
