Securing a child restraint seat withchild seat lower anchor systemSome child seat manufacturers make
child restraint seats that are labeled as
LATCH or LATCH-compatible child
restraint seats. LATCH stands for "Lower
Anchors and Tethers for Children". These
seats include two rigid or webbing
mounted attachments that connect to
two LATCH anchors at specific seating
positions in your vehicle. This type of
child restraint seat eliminates the need to
use seat belts to attach the child seat in
the rear seats. Child restraint symbols are located on
the left and right rear seat backs to indi-
cate the position of the lower anchors for
child restraints.

WARNING
When using the vehicle's "LATCH"
system to install a child restraint
system in the rear seat, all unused
vehicle rear seat belt metal latch
plates or tabs must be latched
securely in their seat belt buckles
and the seat belt webbing must be
retracted behind the child restraint
to prevent the child from reaching
and taking hold of unretracted seat
belts. Unlatched metal latch plates
or tabs may allow the child to reach
the unretracted seat belts which
may result in strangulation and a
serious injury or death to the child
in the child restraint.
WARNING
Install the child restraint seat fully
rearward against the seatback with
the seatback reclined two positions
from the most upright latched posi-
tion.

Noise and smokeWhen the air bags inflate, they make a
loud noise and they leave smoke and
powder in the air inside of the vehicle.
This is normal and is a result of the igni-
tion of the air bag inflator. After the air
bag inflates, you may feel substantial dis-
comfort in breathing due to the contact of
your chest with both the seat belt and the
air bag, as well as from breathing the
smoke and powder.Open your doors
and/or windows as soon as possible
after impact in order to reduce dis-
comfort and prevent prolonged expo-
sure to the smoke and powder.
Though the smoke and powder are non-
toxic, they may cause irritation to the skin
(eyes, nose and throat, etc). If this is the
case, wash and rinse with cold water
immediately and consult a doctor if the
symptom persists.
Do not install a child restraint on the
front passenger’s seat.Never place a rear-facing child restraint
in the front passenger’s seat. If the air
bag deploys, it would impact the rear-fac-
ing child restraint, causing serious or
fatal injury.
In addition, do not place front-facing child
restraints in the front passenger’s seat
either. If the front passenger air bag
inflates, it could cause serious or fatal
injuries to the child.

1JBH3051
WARNING
When the air bags deploy, the air
bag related parts in the steering
wheel and/or instrument panel
and/or in both sides of the roof rails
above the front and rear doors and
in the front set backs are very hot.
To prevent injury, do not touch the
air bag storage area’s internal com-
ponents immediately after an air
bag has inflated.
WARNING
• Extreme Hazard! Do not use a rearward facing child restraint on
a seat protected by an air bag in
front of it!
• Never put a child restraint in the front passenger’s seat. If the front
passenger air bag inflates, it
would cause serious or fatal
injuries.
• When children are seated in the rear outboard seats of a vehicle
equipped with side and/or curtain
air bags, be sure to install the
child restraint system as far away
from the door side as possible,
and securely lock the child
restraint system in position.
Inflation of side and/or curtain air
bags could cause serious injury
or death to an infant or child.

(Continued)
• Do not place an electronic device
such as a laptop computer on the
front passenger seat. Its elec-
tronic field may cause the OCS to
switch to the "on" condition and
thus allow the passenger air bag
to deploy needlessly in a colli-
sion, increasing your repair
costs.
• A smaller-stature adult in the front passenger’ seat who is not
seated correctly (for example:
seat excessively reclined, leaning
on the door or center console, or
hips shifted forward in the seat)
can cause a condition where the
occupant classification system
senses less weight than if the
occupant were seated properly
(sitting upright with the seatback
in an upright position, centered
on the seat cushion with their
seat belt on, legs comfortably
extended and their feet on the
floor).
This condition can result in an
adult potentially being misclassi-
fied as a child and illumination of
the PASS AIR BAG "OFF" indica-
tor.
(Continued)
• Accident statistics show thatchildren are safer if they are
restrained in the rear, as opposed
to the front seat. It is recom-
mended that child restraints be
secured in a rear seat, including
an infant riding in a rear-facing
infant seat, a child riding in a for-
ward-facing child seat and an
older child riding in a booster
seat.
• Air bags can only be used once – have an authorized HYUNDAI
dealer replace the air bag imme-
diately after deployment.
• The occupant classification sys- tem may not work properly if
water, coffee or any other liquid
including rain gets on the seat.
Keep the front seat dry at all
times.
(Continued)
• If the PASS AIR BAG "OFF" indi-cator is illuminated when the
front passenger's seat is occu-
pied by an adult and he/she sits
properly (sitting upright with the
seatback in an upright position,
centered on the seat cushion
with their seat belt on, legs com-
fortably extended and their feet
on the floor), have that person sit
in the rear seat.
• Do not modify or replace the front passenger seat. Don't place any-
thing on or attach anything such
as a blanket or seat heater to the
front passenger seat. This can
adversely affect the occupant
classification system.
• Do not sit on sharp objects such as tools when occupying the
front passenger seat. This can
adversely affect the occupant
classification system.
• Do not use accessory seat cov- ers on the front seats.

The curtain air bags are designed to
deploy only during certain side impact
collisions, depending on the crash sever-
ity, angle, speed and impact. The curtain
air bags are not designed to deploy in all
side impact situations, collisions from the
front or rear of the vehicle or in most
rollover situations.
WARNING
• In order for side and curtain airbags to provide the best protec-
tion, front seat occupants and
outboard rear occupants should
sit in an upright position with the
seat belts properly fastened.
Importantly, children should sit in
a proper child restraint system in
the rear seat.
• When children are seated in the rear outboard seats, they must be
seated in the proper child
restraint system. Make sure to
put the child restraint system as
far away from the door side as
possible, and secure the child
restraint system in a locked posi-
tion.
• Do not allow the passengers to lean their heads or bodies onto
doors, put their arms on the
doors, stretch their arms out of
the window, or place objects
between the doors and passen-
gers when they are seated on
seats equipped with side and/or
curtain air bags.
(Continued)
(Continued)
• Never try to open or repair anycomponents of the side curtain
air bag system. This should only
be done by an authorized
HYUNDAI dealer.
Failure to follow the above instruc-
tions can result in injury or death to
the vehicle occupants in an acci-
dent.

Use only approved portable plas-
tic fuel containers designed to
carry and store gasoline.
• Do not use cellular phones while refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors causing a fire.
• When refueling, always shut the engine off. Sparks produced by
electrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure the
filler cap and filler door are
securely closed, before starting
the engine.
• DO NOT use matches or a lighter and DO NOT SMOKE or leave a lit
cigarette in your vehicle while at
a gas station especially during
refueling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.
(Continued)
(Continued)
• Do not get back into a vehicleonce you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or fab-
ric (polyester, satin, nylon, etc.)
capable of producing static elec-
tricity. Static electricity discharge
can ignite fuel vapors resulting in
rapid burning. If you must re-
enter the vehicle, you should
once again eliminate potentially
dangerous static electricity dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other gaso-
line source.
• When using an approved portable fuel container, be sure to
place the container on the
ground prior to refueling. Static
electricity discharge from the
container can ignite fuel vapors
causing a fire. Once refueling has
begun, contact with the vehicle
should be maintained until the
filling is complete.
