WARNING
- Cargo
Cargo should always be secured to
prevent it from being thrown about
the vehicle in a collision and caus-
ing injury to the vehicle occupants.
Do not place objects in the rear
seats, since they cannot be proper-
ly secured and may hit the front
seat occupants in a collision.
CAUTION
- Rear seat belts
When returning the rear seatbacks
to the upright position, rememberto return the rear shoulder belts totheir proper position. Routing the seat belt webbing through the rearseat belt guides will help keep thebelts from being trapped behind or under the seats.
CAUTION -
Damaging rear
seat belt buckles
When you fold the rear seatback,
insert the buckle in the pocketbetween the rear seatback and cushion. Doing so can prevent thebuckle from being damaged by the rear seatback.
WARNING -
Cargo loading
Make sure the engine is off, the
automatic transaxle is in P (Park)
or the manual transaxle is in R
(Reverse) or 1st, 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 lever is
inadvertently moved to another
position.
WARNING
When you return the rear seatback
to its upright position after being

WARNING
 No modifications or additions should be made by the user
which will either prevent the seat
belt adjusting devices from oper-
ating to remove slack, or prevent
the seat belt assembly from being
adjusted to remove slack.
 When you fasten the seat belt, be careful not to latch the seat belt in
buckles of other seat. It's very dan-
gerous and you may not be pro-
tected by the seat belt properly.
 Do not unfasten the seat belt and do not fasten and unfasten the
seat belt repeatedly while driving.
This could result in loss of con-
trol, and an accident causing
death, serious injury, or property
damage.
 When fastening the seat belt, make sure that the seat belt does
not pass over objects that are
hard or can break easily.
 Make sure there is nothing in the buckle. The seat belt may not be
fastened securely.

Seat belts - Front passenger and rearseat 3-point system with combination locking retractorTo 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.
✽ ✽
NOTICEAlthough 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.

WARNING
You should place the lap belt por-
tion as low as possible and snugly
across your hips, not on your waist.
If the lap belt is located too high on
your waist, it may increase the
chance of injury in the event of a
collision. Both arms should not be
under or over the belt. Rather, one
should be over and the other under,
as shown in the illustration.
Never wear the seat belt under the
arm nearest the door.

3Infant or small childAll 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.
✽ ✽
NOTICESmall 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 childrenChildren 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.

329
Safety features of your vehicleWARNING
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 SYSTEMChildren 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 statis-
tics, 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 meets 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 man-
ufacturer when installing the child
restraint system.
WARNING
 A child restraint system must beplaced 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 systemFor 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.

Safety features of your vehicle
For safety reasons, we recommend that
the child restraint system be used in the
rear seats.
Since all passenger seat belts move
freely under normal conditions and only
lock under extreme or emergency condi-
tions (emergency locking mode), you
must manually change these seat belts
to the automatic locking mode to secure
a child restraint.
Placing a passenger seat belt intothe automatic locking mode The automatic locking mode will help
prevent the normal movement of the
child in the vehicle from causing the seat
belt to loosen and compromise the child
restraint system. To secure a child
restraint system, use the following proce-
dure.
WARNING
- Child seat
installation
 A child can be seriously injured or killed in a collision if the child
restraint is not properly anchored
to the vehicle and the child is not
properly restrained in the child
restraint. Before installing the
child restraint system, read the
instructions supplied by the child
restraint system manufacturer.
 If the seat belt does not operate as described in this section, have
the system checked immediately
by your authorized HYUNDAI
dealer.
 Failure to observe this manual's instructions regarding child
restraint systems and the
instructions provided with the
child restraint system could
increase the chance and/or
severity of injury in an accident.
WARNING
Never place a rear-facing child
restraint in the front passenger
seat, because of the danger that an
inflating passenger-side air bag
could impact the rear-facing child
restraint and kill the child.
