Safety features of your vehicle
The front air bag modules are locat-
ed in the center of the steering
wheel, in the front passenger's panel
above the glove box and in the dri-
ver’s side knee bolster. When the
SRSCM detects a sufficiently severe
impact to the front of the vehicle, it
will automatically deploy the front air
bags.Upon deployment, tear seams mold-
ed directly into the pad covers will
separate under pressure from the
expansion of the air bags. Further
opening of the covers then allows full
inflation of the air bags.A fully inflated air bag, in combina-
tion with a properly worn seat belt,
slows the driver's or the passenger's
forward motion, reducing the risk of
head and chest injury.
After complete inflation, the air bag
immediately starts deflating,
enabling the driver to maintain for-
ward visibility and the ability to steer
or operate other controls.

Passenger’s front air bag
WARNING
Do not install or place any
accessories (drink holder, CD
or discs holder, sticker, etc.)
on the front passenger's
panel above the glove box in a
vehicle with a passenger's air
bag. Such objects may
become dangerous projec-
tiles and cause injury if the
passenger's air bag inflates.
(Continued)
(Continued)
When installing a container of
liquid air freshener inside the
vehicle, do not place it near
the instrument cluster nor on
the instrument panel surface.
It may become a dangerous
projectile and cause injury if
the passenger's air bag
inflates.WARNING
If an air bag deploys, there
may be 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
aggravate asthma for some
persons. Always wash all
exposed skin areas thorough-
ly 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.

Safety features of your vehicle
Occupant classification system
Your vehicle is equipped with an
occupant 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 classification 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.
An indicator light located on the
instrument panel which illuminates
the words PASS AIR BAG "OFF"
indicating the front passenger air
bag system is deactivated.
The instrument panel air bag indi-
cator light is interconnected with
the occupant classification system.
(Continued)
If the SRS air bag warning light
" " does not illuminate, 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.
Before you replace a fuse or
disconnect a battery terminal,
turn the ignition switch to the
LOCK position and remove
the ignition key for ignition
key, and turn the engine
start/stop button to the OFF
position for smart key. Never
remove or replace the air bag
related fuse(s) when the igni-
tion switch is in the ON posi-
tion. Failure to heed this warn-
ing will cause the SRS air bag
warning light to illuminate.

If the front passenger seat is occu-
pied by a person that the system
determines to be of adult size, and
he/she sits properly (sitting upright
with the seatback in an upright posi-
tion, centered on the seat cushion
with their seat belt on, legs comfort-
ably 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 condi-
tions 1~4 in the following table and
activates or deactivates the front
passenger air bag based on these
conditions.Always be sure that you and all vehi-
cle 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 comfortably
extended, feet on the floor, and wear-
ing the safety belt properly) for the
most effective protection by the air
bag and the safety belt. The OCS may not function proper-
ly if the passenger takes actions
which can affect the classification
system. These include:
(1) Failing to sit in an upright posi-
tion.
(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 loca-
tions which reduce the passen-
ger weight on the front seat.
(5) Improperly wearing the safety
belt.
(6) Reclining the seat back.

Safety features of your vehicle
Condition 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 pas-
senger seat, the system may rec-
ognize 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 passenger seat, the system
may recognize him/her as an
adult depending upon his/her
physique or sitting position.*3) Never install a child restraint sys-
tem on the front passenger seat.
*4) The PASS AIR BAG "OFF" indi-
cator may turn on or off when a
child above 12 months to 12
years old (with or without child
restraint system) sits in the front
passenger seat. This is a normal
condition.
WARNING - OCS system
Riding in an improper position
adversely affects the occupant
classification system (OCS) and
may result in the deactivation of
front passenger airbag. It is
important for the driver to
instruct the passenger as to the
proper seating instructions as
contained in this manual.

Safety features of your vehicle
When an adult is seated in the front
passenger seat, if the PASS AIR
BAG “OFF” indicator is on, turn the
ignition switch to the LOCK or OFF
position and ask the passenger to sit
properly (sitting upright with the seat
back in an upright position, centered
on the seat cushion with their seat
belt on, legs comfortably extended
and their feet on the floor). Restart
the engine and have the person
remain in that position. This will allow
the system to detect the person and
to enable the passenger air bag.If the PASS AIR BAG "OFF" indicator
is still on, ask the passenger to move
to the rear seat.
✽ ✽
NOTICE
The PASS AIR BAG "OFF" indica-
tor illuminates for about 4 seconds
after the ignition switch is turned to
the ON position or after the engine is
started. If the front passenger seat is
occupied, the occupant classification
sensor will then classify the front pas-
senger after several more seconds.

Proper position
WARNING
Do not hang onto the front pas-
senger seat. Do not hang any
items, such as a seatback table
or entertainment system on the
front passenger seatback. Do
not place feet on the front pas-
senger seatback. Do not place
any items under the front pas-
senger seat. Any of these could
interfere with proper sensor
operation.
WARNING - AIR BAG
"OFF" light
Do not allow an adult passenger
to ride in the front seat when the
PASS AIR BAG “OFF” indicator
is illuminated, because the air
bag will not deploy in the event
of a crash. The driver must
instruct the passenger to repo-
sition himself in the seat.
Failure to properly position
yourself may lead to airbag
deactivation resulting in airbag
non-deployment in a collision. If
the PASS AIR BAG “OFF” indi-
cator remains illuminated after
the passenger repositions
themselves properly and the
vehicle is restarted, it is recom-
mended the passenger move to
the rear seat because the pas-
senger's front air bag will not
deploy.

WARNING
Even though your vehicle is
equipped with the occupant
classification system, never
install a child restraint system
in the front passenger's seat.
A deploying air bag can force-
fully strike a child resulting in
serious injuries or death. Any
child age 12 and under should
ride in the rear seat. Children
too large for child restraints
should use the available
lap/shoulder belts. No matter
what type of crash, children of
all ages are safer when
restrained in the rear seat.

(Continued)
If the PASS AIR BAG "OFF"
indicator is illuminated when
the front passenger's seat is
occupied 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 comfortably
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 anything on or attach
anything such as a blanket or
seat heater to the front pas-
senger seat. This can adverse-
ly affect the occupant classifi-
cation system.
Do not sit on sharp objects
such as tools when occupying
the front passenger seat. This
can adversely affect the occu-
pant classification system.
(Continued)WARNING - Folding
rear seat
Never let the rear seat touch the
front passenger seat when fold-
ing the rear seat. The occupant
classification system (OCS)
may malfunction, the PASS AIR
BAG "OFF" indicator may turn
on even though the front pas-
senger's seat is occupied by an
adult, or the SRS air bag warn-
ing light on the instrument
panel may illuminate.

Safety features of your vehicle
WARNING
If the occupant classification
system is not working properly,
the SRS air bag warning light
on the instrument panel will illu-
minate because the passenger's
front air bag is connected with
the occupant classification sys-
tem. If there is a malfunction of
the occupant classification sys-
tem, 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 occu-
pant in the front passenger's
seat. If the SRS air bag warning
light does not illuminate when
the ignition switch is turned to
the ON position, remains illumi-
nated after approximately 6 sec-
onds when the ignition switch is
turned to the ON position, or if it
illuminates while the vehicle is
being driven, have an author-
ized HYUNDAI dealer inspect
the occupant classification sys-
tem and the SRS air bag system
as soon as possible.
(Continued)
A smaller-stature adult in the
front passenger’ seat who is
not seated correctly (for exam-
ple: seat excessively reclined,
leaning on the door or center
console, or hips shifted for-
ward in the seat) can cause a
condition where the occupant
classification system senses
less weight than if the occu-
pant were seated properly (sit-
ting upright with the seatback
in an upright position, cen-
tered on the seat cushion with
their seat belt on, legs com-
fortably extended and their
feet on the floor).
This condition can result in an
adult potentially being mis-
classified and illumination of
the PASS AIR BAG "OFF" indi-
cator.(Continued)
Do not use accessory seat
covers on the front seats.
Accident statistics show that
children are safer if they are
restrained in the rear, as
opposed to the front seat. It is
recommended that child
restraints be secured in a rear
seat, including an infant riding
in a rear-facing infant seat, a
child riding in a forward-fac-
ing 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 immediately after
deployment.
