Seat belts - Front passenger and rearseat 3-point system with combinationlocking retractor
To fasten your seat belt:
Combination retractor type seat belts are
installed in the rear seat positions to help
accommodate the installation of child
restraint systems. Although a combina-
tion retractor is also installed in the front
passenger seat position, it is strongly
recommended that children always be
seated in the rear seat. NEVER place
any infant restraint system in the front
seat of the vehicle.
This type of seat belt combines the fea-
tures of both an emergency locking
retractor seat belt and an automatic lock-
ing retractor seat belt. To fasten your seat
belt, pull it 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 around your hips. When the seat belt is fully extended from
the retractor to allow the installation of a
child restraint system, the seat belt oper-
ation changes to allow the belt to retract,
but not to extend (Automatic Locking
Retractor Type). Refer to “Using a child
restraint system” in this section.
✽ ✽
NOTICE
Although the combination retractor
provides the same level of protection for
seated passengers in either emergency
or automatic locking modes, it is recom-
mended that seated passengers use the
emergency locking feature for improved
convenience. The automatic locking
function is intended to facilitate child
restraint installation. To convert from
the automatic locking feature to the
emergency locking operation mode,
allow the unbuckled seat belt to fully
retract.
Rear center seat belt
To fasten the rear center seat belt, insert
the metal tab(1) into the buckle(2) until
an audible "click" is heard. Make sure
that the belt is not twisted and there is
"CENTER" mark on the buckle.

Infant or small child
All 50 states have child restraint laws. You
should be aware of the specific require-
ments in your state. Child and/or infant
seats must be properly placed and
installed in the rear seat. For more infor-
mation about the use of these restraints,
refer to “Child restraint system” in this
section.✽ ✽
NOTICE
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 require-
ments 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
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 “Child
restraint system” in this section.
Larger children
Children who are too large for child
restraint systems should always occupy
the rear seat and use the available
lap/shoulder belts. The lap portion should
be fastened snug on the hips and as low
as possible. Check belt fit periodically. A
child's squirming could put the belt out of
position. Children are afforded the most
safety in the event of an accident when
they are restrained by a proper restraint
system in the rear seat. If a larger child
(over age 12) must be seated in the front
seat, the child should be securely
restrained by the available lap/shoulder
belt and the seat should be placed in the
rearmost position. Children age 12 and
under should be restrained securely in
the rear seat. NEVER place a child age
12 and under in the front seat. NEVER
place a rear facing child seat in the front
seat of a vehicle.
WARNING
Every person in your vehicle needs
to be properly restrained at all
times, including infants and chil-
dren. Never hold a child in your
arms or lap when riding in a vehi-
cle. The violent forces created dur-
ing a crash will tear the child from
your arms and throw the child
against the interior. Always use a
child restraint appropriate for your
child's height and weight.

Safety features of your vehicle
WARNING
To reduce the chance of serious or
fatal injuries:
Children of all ages are saferwhen restrained in the rear seat.
A child riding in the front passen-
ger seat can be forcefully struck
by an inflating air bag resulting in
serious or fatal injuries.
Always follow the child restraint system manufacturer’s instruc-
tions for installation and use of
the child restraint.
Always make sure the child seat is secured properly in the car and
your child is securely restrained
in the child seat.
Never hold a child in your arms or lap when riding in a vehicle. The
violent forces created during a
crash will tear the child from your
arms and throw the child against
the car’s interior.
Never put a seat belt over your- self and a child. During a crash,
the belt could press deep into the
child causing serious internal
injuries.
(Continued)
CHILD RESTRAINT SYSTEM
Children riding in the car should sit in the
rear seat 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. Larger children not in a child restraint
should use one of the seat belts provided.
You should be aware of the specific
requirements in your state. Child and/or
infant safety seats must be properly
placed and installed in the rear seat. You
must use a commercially available child
restraint system that m eets the require-
ments of the Federal Motor Vehicle Safety
Standards (FMVSS).
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the
lap belt portion of a lap/shoulder belt, or
by a LATCH system (if equipped).
Children could be injured or killed in a
crash if their restraints are not properly
secured. For small children and babies, a
child seat or infant seat must be used.
Before buying a particular child restraint
system, make sure it fits your car seat and
seat belts, and fits your child. Follow all the
instructions provided by the manufacturer
when installing the child restraint system.
WARNING
A child restraint system must be placed in the rear seat. Never
install a child or infant seat on the
front passenger's seat. Should an
accident occur and cause the
passenger-side air bag to deploy,
it could severely injure or kill an
infant or child seated in an infant
or child seat. Thus only use a
child restraint in the rear seat of
your vehicle.
A seat belt or child restraint sys- tem can become very hot if it is
left in a closed vehicle on a sunny
day, even if the outside tempera-
ture does not feel hot. Be sure to
check the seat cover and buckles
before placing a child there.
When the child restraint system is not in use, store it in the lug-
gage area or fasten it with a seat
belt so that it will not be thrown
forward in the case of a sudden
stop or an accident.
Children may be seriously injured or killed by an inflating air bag.
All children, even those too large
for child restraints, must ride in
the rear seat.

Using a child restraint system
For small children and babies, the use of
a child seat or infant seat is required. This
child seat or infant seat should be of
appropriate size for the child and should
be installed in accordance with the man-
ufacturer's instructions.
(Continued)
Never leave children unattended
in a vehicle – not even for a short
time. The car can heat up very
quickly, resulting in serious
injuries to children inside. Even
very young children may inadver-
tently cause the vehicle to move,
entangle themselves in the win-
dows, or lock themselves or oth-
ers inside the vehicle.
Never allow two children, or any two persons, to use the same
seat belt.
Children often squirm and repo- sition themselves improperly.
Never let a child ride with the
shoulder belt under their arm or
behind their back. Always proper-
ly position and secure children in
the rear seat.
Never allow a child to stand-up or kneel on the seat or floor of a
moving vehicle. During a colli-
sion or sudden stop, the child
can be violently thrown against
the vehicle’s interior, resulting in
serious injury.
(Continued)(Continued)
Never use an infant carrier or achild safety seat that "hooks"
over a seatback, it may not pro-
vide adequate security in an acci-
dent.
Seat belts can become very hot, especially when the car is parked
in direct sunlight. Always check
seat belt buckles before fasten-
ing them over a child.
After an accident, have an author- ized HYUNDAI dealer check the
child restraint system, seat belt,
tether anchor and lower anchor.
If there is not enough space to place the child restraint system
because of the driver's seat,
install the child restraint system
in the rear right seat.
