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.

 Do not install or place any acces-sories (drink holder, CD or discs
holder, sticker, etc.) on the front
passenger's panel above the
glove box in a vehicle with a pas-
senger's air bag. Such objects
may become dangerous projec-
tiles and cause injury if the pas-
senger's air bag inflates.
 When installing a container of liq- uid air freshener inside the vehi-
cle, do not place it near the
instrument cluster nor on the
instrument panel surface.
It may become a dangerous pro-
jectile and cause injury if the pas-
senger's air bag inflates.

Passenger’s front air bag
WARNING
 If an air bag deploys, there maybe a loud noise followed by a fine
dust released in the vehicle.
These conditions are normal and
are not hazardous - the air bags
are packed in this fine powder.
The dust generated during air
bag deployment may cause skin
or eye irritation as well as aggra-
vate asthma for some persons.
Always wash all exposed skin
areas thoroughly with lukewarm
water and a mild soap after an
accident in which the air bags
were deployed.
 The SRS can function only when the ignition switch is in the ON
position. If the SRS air bag warn-
ing light " " does not illumi-
nate, or continuously remains on
after illuminating for about 6 sec-
onds when the ignition switch is
turned to the ON position, or after
the engine is started, comes on
while driving, the SRS is not
working properly. If this occurs,
have your vehicle immediately
inspected by an authorized
HYUNDAI dealer.
(Continued)
(Continued)
 Before you replace a fuse or dis-connect a battery terminal, turn
the ignition switch to the LOCK
position and remove the ignition
key. Never remove or replace the
air bag related fuse(s) when the
ignition switch is in the ON posi-
tion. Failure to heed this warning
will cause the SRS air bag warn-
ing light to illuminate.

3Occupant classification systemYour vehicle is equipped with an occu-
pant classification system in the front
passenger's seat. The occupant classification system is
designed to 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 driver's front air bag is not affected
or controlled by the occupant classifica-
tion system.
Main components of occupant
classification system A detection device located within the
front passenger seat frame.
 Electronic system to determine whether the front passenger air bag system
should be activated or deactivated.
 A warning light located on the instru- ment panel which illuminates the words
PASS AIR BAG "OFF" indicating the
front passenger air bag system is deac-
tivated.
 The instrument panel air bag warning light is interconnected with the occupant
classification system.
If the front passenger seat is occupied by
a person that the system determines to be
of adult size, and he/she sits properly (sit-
ting 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), the
PASS AIR BAG "OFF" indicator will be
turned off and the front passenger's air
bag will be able to inflate, if necessary, in
frontal crashes.
You will find the PASS AIR BAG "OFF"
indicator on the center facia panel. This
system detects the conditions 1~4 in the
following table and activates or deacti-
vates the front passenger air bag based
on these conditions.

Safety features of your vehicle
Always be sure that you and all vehicle
occupants are seated and restrained
properly (sitting upright with the seat in
an upright position, centered on the seat
cushion, with the person's legs comfort-
ably extended, feet on the floor, and
wearing the safety belt properly) for the
most effective protection by the air bag
and the safety belt.
 The OCS may not function properly ifthe passenger takes actions which can
affect the classification system. These
include:
(1) Failing to sit in an upright position.
(2) Leaning against the door or center console.
(3) Sitting towards the sides or the front of the seat.
(4) Putting legs on the dashboard or resting them on other locations
which reduce the passenger weight
on the front seat.
(5) Improperly wearing the safety belt.
(6) Reclining the seat back.
C040301ABHCondition and operation in the front passenger occupant classification system*1) The system judges a person of adult size as an adult. When a smaller adult
sits in the front passenger seat, the
system may recognize him/her as a
child depending on his/her physique
and posture.
*2) Do not allow children to ride in the front passenger seat. When a larger
child who has outgrown a child
restraint system sits in the front pas-
senger seat, the system may recog-
nize him/her as an adult depending
upon his/her physique or sitting posi-
tion. *3) Never install a child restraint system
on the front passenger seat.
WARNING
Riding in an improper position or
placing weight on the front passen-
ger's seat when it is unoccupied by
a passenger adversely affects the
occupant classification system
(OCS).

Driver's and passenger's front air
bagYour vehicle is equipped with a
Supplemental Restraint (Air Bag) System
and lap/shoulder belts at both the driver
and passenger seating positions. The
indications of the system's presence are
the letters "SRS AIR BAG" or “AIR BAG"
embossed on the air bag pad cover in the
steering wheel and the passenger's side
front panel pad above the glove box.
The SRS consists of air bags installed
under the pad covers in the center of the
steering wheel and the passenger's side
front panel above the glove box.The purpose of the SRS is to provide the
vehicle's driver and/or the front passen-
ger with additional protection than that
offered by the seat belt system alone in
case of a frontal impact of sufficient
severity. The SRS uses sensors to gath-
er information about the driver's seat
position, the driver's and front passen-
ger's seat belt usage and impact severi-
ty.
OYF039030
Driver’s front air bag
WARNING
If the occupant classification sys-
tem is not working properly, the
SRS air bag warning light on the
instrument panel will illuminate
because the passenger's front air
bag is connected with the occupant
classification system. If there is a
malfunction of the occupant classi-
fication system, the PASS AIR BAG
"OFF" indicator will not illuminate
and the passenger's front air bag
will inflate in frontal impact crashes
even if there is no occupant in the
front passenger's seat. If the SRS
air bag warning light does not illu-
minate when the ignition switch is
turned to the ON position, remains
illuminated after approximately 6
seconds when the ignition switch is
turned to the ON position, or if it
illuminates while the vehicle is
being driven, have an authorized
HYUNDAI dealer inspect the occu-
pant classification system and the
SRS air bag system as soon as
possible.

The driver's seat track position sensor,
which is installed on the seat track, deter-
mines if the seat is fore or aft of a refer-
ence position. The seat belt buckle sen-
sors determine if the driver and front pas-
senger's seat belts are fastened. These
sensors provide the ability to control the
SRS deployment based on how close the
driver's seat is to the steering wheel,
whether or not the seat belts are fas-
tened, and how severe the impact is.
The advanced SRS offers the ability to
control the air bag inflation within two lev-
els. A first stage level is provided for mod-
erate-severity impacts. A second stage
level is provided for more severe impacts.
According to the impact severity, seating
position and seat belt usage, the SRSCM
(SRS Control Module) controls the air
bag inflation. Failure to properly wear
seat belts can increase the risk or sever-
ity of injury in an accident. Additionally, your vehicle is equipped
with an occupant classification system in
the front passenger's seat. The occupant
classification system detects the pres-
ence of a passenger in the front passen-
ger's seat and will turn off the front pas-
senger's air bag under certain condi-
tions. For more detail, see "Occupant
classification system" in this section.
WARNING
If the occupant classification sys-
tem is not working properly, the
SRS air bag warning light on the
instrument panel will illuminate
because the SRS air bag warning
light is connected with the occu-
pant classification system. If the
SRS air bag warning light does not
illuminate when the ignition switch
is turned to the ON position,
remains illuminated after approxi-
mately 6 seconds when the ignition
switch is turned to the ON position,
or if it illuminates while the vehicle
is being driven, have an authorized
HYUNDAI dealer inspect the
advanced SRS air bag system as
soon as possible.
WARNING
 Modification to the seat structure
can adversely affect the seat
track position sensor and cause
the air bag to deploy at a different
level than should be provided.
 Do not place any objects under- neath the front seats as they
could damage the seat track
position sensor or interfere with
the occupant classification sys-
tem.
 Do not place any objects that may cause magnetic fields near the
front seat. These may cause a
malfunction of the seat track
position sensor.

(Continued)
 Even though your vehicle is
equipped with the occupant clas-
sification system, do not install a
child restraint system in the front
passenger seat position. A child
restraint system must never be
placed in the front seat. The infant
or child could be severely injured
or killed by an air bag deployment
in case of an accident.
 Children age 12 and under must always be properly restrained in
the rear seat. Never allow chil-
dren to ride in the front passen-
ger seat. If a child over 12 must
be seated in the front seat, he or
she must be properly belted and
the seat should be moved as far
back as possible.
 For maximum safety protection in all types of crashes, all occu-
pants including the driver should
always wear their seat belts
whether or not an air bag is also
provided at their seating position
to minimize the risk of severe
injury or death in the event of a
crash. Do not sit or lean unneces-
sarily close to the air bag while
the vehicle is in motion.
(Continued)
(Continued)
 No objects should be placed overor near the air bag modules on
the steering wheel, instrument
panel, and the front passenger's
panel above the glove box,
because any such object could
cause harm if the vehicle is in a
crash severe enough to cause
the air bags to deploy.
 Never place covers, blankets or seat warmers on the passenger
seat as these may interfere with
the occupant classification sys-
tem.
 Do not tamper with or disconnect SRS wiring or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental deployment of the air bags
or by rendering the SRS inopera-
tive.
 If the SRS air bag warning light remains illuminated while the
vehicle is being driven, have an
authorized HYUNDAI dealer
inspect the air bag system as
soon as possible.
(Continued)
(Continued)
 Air bags can only be used once –have an authorized HYUNDAI
dealer replace the air bag imme-
diately after deployment.
 The SRS is designed to deploy the front air bags only when an
impact is sufficiently severe and
when the impact angle is less
than 30° from the forward longitu-
dinal axis of the vehicle.
Additionally, the air bags will only
deploy once. Seat belts must be
worn at all times.
 Front air bags are not intended to deploy in side-impact, rear-
impact or rollover crashes. In
addition, front air bags will not
deploy in frontal crashes below
the deployment threshold.

SRS CareThe SRS is virtually maintenance-free
and so there are no parts you can safely
service by yourself. If the SRS air bag
warning light " " does not illuminate,
when you turn the ignition on, or continu-
ously remains on, have your vehicle
immediately inspected by an authorized
HYUNDAI dealer.
Any work on the SRS system, such as
removing, installing, repairing, or any
work on the steering wheel, the front
passenger's panel, front seats and roof
rails must be performed by an authorized
HYUNDAI dealer. Improper handling of
the SRS system may result in serious
personal injury.
WARNING
 Modification to SRS componentsor wiring, including the addition
of any kind of badges to the pad
covers or modifications to the
body structure, can adversely
affect SRS performance and lead
to possible injury.
 Not only the modification of the parts where the SRS sensors are
but also the modification of other
parts of the vehicle may affect the
SRS performance and lead to
possible injury.
 For cleaning the air bag pad cov- ers, use only a soft, dry cloth or
one which has been moistened
with plain water. Solvents or
cleaners could adversely affect
the air bag covers and proper
deployment of the system.
No objects should be placed over
or near the air bag modules on the
steering wheel, instrument panel,
and the front passenger's panel
above the glove box, because any
such object could cause harm if the
vehicle is in a crash severe enough
to cause the air bags to inflate.
(Continued)
(Continued)
 If the air bags inflate, they must be replaced by an authorized
HYUNDAI dealer.
 Do not tamper with or disconnect SRS wiring, or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental inflation of the air bags or
by rendering the SRS inopera-
tive.
 If components of the air bag sys- tem must be discarded, or if the
vehicle must be scrapped, certain
safety precautions must be
observed. An authorized
HYUNDAI dealer knows these
precautions and can give you the
necessary information. Failure to
follow these precautions and pro-
cedures could increase the risk
of personal injury.
 If your car was flooded and has soaked carpeting or water on the
flooring, you shouldn't try to start
the engine; have the car towed to
an authorized HYUNDAI dealer.
