NOTICE
Before you replace a fuse or discon-
nect a battery terminal, change the
ignition switch to the OFF position.
Never remove or replace the air bag
related fuse(s) when the ignition
switch is in the ON position. Failure
to heed this warning will cause the
SRS air bag warning light to illumi-
nate.
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 cushion.
Electronic system to determine whether passenger air bag sys-
tems should be activated or deacti-
vated.
A warning light located on the instrument panel which illuminates
the words PASSENGER AIR BAG
“OFF” indicating the front passen-
ger air bag system is deactivated.
The instrument panel air bag warn- ing light is interconnected with the
occupant classification system.

Safety features of your vehicle
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 PASSENGER AIR BAG
“OFF” indicator will turn off and the
front passenger's air bag will be able
to inflate, if necessary, in frontal
crashes. You will find the PASSENGER AIR
BAG “OFF” indicator on the center
facia panel.
This system detects conditions 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 seat belt. The OCS (Occupant Classification
System) may not function properly
if the 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 cen- ter 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 seat belt.
(6) Reclining the seat back.

Condition and operation in the front passenger occupant classifica-
tion 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 passen-
ger seat, the system may recognize him/her as an adult depending on
his/her physique or posture.
*3) Never install a child restraint system on the front passenger seat.
WARNING - OCS system
Riding in an improper position
adversely affects the occupant
classification system (OCS) and
may result in the deactivation of

When an adult is seated in the front
passenger seat, if the PASSENGER
AIR BAG “OFF” indicator is on,
change the ignition switch to the 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 PASSENGER AIR BAG “OFF”
indicator is still on, ask the passen-
ger to move to the rear seat.
✽ ✽
NOTICE
The PASSENGER AIR BAG “OFF”
indicator illuminates for about 4 sec-
onds after the ignition switch is
changed to the ON position or after
the engine is started. If the front
passenger seat is occupied, the occu-
pant classification sensor will then
classify the front passenger after
several more seconds.

WARNING - AIR BAG
"OFF" light
Do not allow an adult passenger
to ride in the front seat when the
PASSENGER 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 reposition himself
in the seat. Failure to properly
position yourself may lead to
airbag deactivation resulting in
airbag non-deployment in a col-
lision. If the PASSENGER AIR
BAG “OFF” indicator remains
illuminated after the passenger
repositions themselves proper-
ly and the vehicle is restarted, it
is recommended the passenger
move to the rear seat because
the passenger's front air bag
will not deploy.

347
Safety features of your vehicle
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.
✽ ✽NOTICE
Do not modify or replace the front
passenger seat. Do not place any-
thing on or attach anything such as
a blanket, front seat covers or after
market seat heater to the front pas-
senger seat. This can adversely
affect the occupant classification
system.
If the occupant classification system
is not working properly, the SRS air
bag warning light on the instrument
panel will illuminate because the
passenger's front air bag is connect-
ed with the occupant classification
system. If there is a malfunction of
the occupant detection system, the
PASSENGER AIR BAG “OFF” indi-
cator will not illuminate and the pas-
senger's front air bag will inflate in
frontal impact crashes even if there is
no occupant in the front passenger's
seat.

Your vehicle is equipped with an
Advanced Supplemental Restraint
(Air Bag) System (SRS) and the
lap/shoulder belts at both the driver
and passenger seating positions.
The indications of the system's pres-
ence are the letters "AIR BAG"
embossed on the air bag pad cover
in the steering wheel and/or on the
cover of the driver's side knee bolster
located below 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, in the
knee bolster below the steering
wheel column 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
passenger with additional protection
than that offered by the seat belt sys-
tem alone in case of a frontal impact
of sufficient severity. The SRS uses
sensors to gather information about
the driver's and front passenger's
seat belt usage and impact severity. The seat belt buckle sensors deter-
mine if the driver and front passen-
ger's seat belts are fastened.
These sensors provide the ability to
control the SRS deployment based on
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 levels. A first stage level is pro-
vided for moderate-severity impacts.
A second stage level is provided for
more severe impacts.
According to the impact severity 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
severity of injury in an accident.
Additionally, your vehicle is equipped
with an occupant classification sys-
tem in the front passenger's seat.
The occupant classification system
detects the presence of a passenger
in the front passenger's seat and will
turn off the front passenger's air bag
under certain conditions. For more
detail, see "Occupant classification
system" in this section.
WARNING
Do not place any objects
underneath the front seats as
they could interfere with the
occupant classification sys-
tem.
Do not place or charge an electronic device such as a
laptop computer on the front
passenger seat. Its electronic
field may cause the OCS to
switch to the "on" condition
and thus allow the passenger
air bag to deploy needlessly
in a collision, increasing your
repair costs.

Safety features of your vehicle
Manufacturers are required by gov-
ernment regulations to provide a
contact point concerning modifica-
tions to the vehicle for persons with
disabilities, which modifications may
affect the vehicle’s advanced air bag
system. That contact is HYUNDAI
Customer Assistance center at 1-
800-633-5151. However, HYUNDAI
does not endorse nor will it support
any changes to any part or structure
of the vehicle that could affect the
advanced air bag system, including
the occupant classification system.Advanced air bags are combined with
pre-tensioner seat belts to help pro-
vide enhanced occupant protection in
frontal crashes. Front air bags are not
intended to deploy in collisions in
which sufficient protection can be pro-
vided by the pre-tensioner seat belt.
✽ ✽
NOTICE
Air bags can only be used once -
have an authorized HYUNDAI deal-
er replace the air bag immediately
after deployment.
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 crash-
es below the deployment threshold.
WARNING - Replacement/
Modifications

board or door should not be
replaced except by an author-
ized HYUNDAI dealer using orig-
inal HYUNDAI parts designed
for this vehicle and model. Any
other such replacement or mod-
ification could adversely affect
the operation of the occupant
classification system and your
advanced air bags.
WARNING - SRS Wiring
Do not tamper with or discon-
nect SRS wiring or other com-
ponents of the SRS system.
Doing so could result in injury,
due to accidental deployment of
the air bags or by rendering the
SRS inoperative.

Side impact air bag
Your vehicle is equipped with a side
impact air bag in each front and out-
board rear seat. The purpose of the
air bag is to provide occupants with
additional protection than that
offered by the seat belt alone.
The side impact air bags are
designed to deploy only during cer-
tain side-impact collisions, depend-
ing on the crash severity, angle,
speed and point of impact. The side
air bags are not designed to deploy
in all side impact situations or in all
rollover situations. Side impact
airbags are deployed if the rollover or
the possible rollover event is detect-
ed by ACU (Airbag Control Unit).

Safety features of your vehicle
Side impact air bags are supplemen-
tal to the seat belt systems and are
not a substitute for them. Therefore
your seat belts must be worn at all
times while the vehicle is in operation.
For best protection from the side air
bag system and to avoid being
injured by the deploying side air bag,
all seat occupants should sit in an
upright position with the seat belt
properly fastened.
The driver's hands should be placed
on the steering wheel at the 9:00 and
3:00 positions. The passenger's
arms and hands should be placed on
their laps.If seat or seat cover is damaged, have
the vehicle checked and repaired by
an authorized HYUNDAI dealer.
Curtain air bag
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors.
WARNING - Deployment
Do not install any accessories
including seat covers, on the
side or near the side impact air
bag as this may affect the
deployment of the side air bags.
WARNING
Do not place any objects over
the air bag or between the air
bag and yourself. Also, do not
attach any objects around the
area the air bag inflates such as
the door, side door glass, front
and rear pillar.
WARNING - Flying
objects
Do not place any objects (an
umbrella, bag, etc.) between the
door and seat. Such objects
may become dangerous projec-
tiles if the side airbag inflates,
which may result in serious
injuries to the occupants.
