The SRS uses sensors to gather information
about the driver's and front passenger's seat
position, the driver's and front passenger's seat
belt usage and impact severity.
The driver's and front passenger's seat track
position sensors, which are installed on the seat
track, determine if the seats are fore or aft of a
reference position. The seat belt buckle sen-
sors determine if the driver and front passenger'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, how close the passenger's seat is to the
instrument panel, whether or not the seat belts
are fastened, and how severe the impact is.
The advanced SRS offers the ability to control
the airbag inflation with two levels. A first stage
level is provided for moderate-severity impacts.
A second stage level is provided for more
severe impacts.
According to the impact severity, seating posi-
tion and seat belt usage, the SRSCM(SRS
Control Module) controls the airbag inflation.
Failure to properly wear seat belts can increase
the risk or severity of injury in an accident.
CAUTION:
If a seat track position sensor or an occu-
pant classification system is not working
properly, the SRS airbag warning light on
the instrument panel will illuminate be-
cause the SRS airbag warning light is con-
nected with the seat track position sensor
and the occupant classification system. If
the SRS airbag warning light does not illu-
minate when the ignition key is turned to
the "ON" position, remains illuminated af-
ter approximately 6 seconds when the igni-
tion key 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 airbag system as
soon as possible.

Additionally, your Hyundai is equipped with an
occupant classification system 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 airbag under certain condi-
tions. For more detail, see "Occupant Classifi-
cation System" later in this section.
B240A01NF-AATDriver's and Passenger's Front AirbagYour Hyundai is equipped with an advanced
Supplemental Restraint (Airbag) System. The
indications of the system's presence are the
letters "SRS AIRBAG" embossed on the airbag
pad cover in the steering wheel and the
passenger's side front panel pad above the
glove box.
The Hyundai SRS consists of airbags 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 passenger with additional protection than
that offered by the seat belt system alone in
case of a frontal impact of sufficient severity.Driver's Front Airbag

o The driver should sit back as far as
possible while still maintaining control
of the vehicle. If you are sitting too close
to the airbag, it can cause death or seri-
ous injury when it inflates.
WARNING:
o Front airbags are not intended to deploy
in side-impact, rear-impact or rollover
crashes. In addition, front airbags will
not deploy in frontal crashes below the
deployment threshold.
!
WARNING:
o As its name implies, the SRS is designed
to work with, and be supplemental to the
driver's and the passenger's three point
seat belt systems and is not a substitute
for them. Therefore, your seat belts must
be worn at all times. The airbags deploy
only in certain frontal impact conditions
severe enough to cause significant in-
jury to the vehicle occupants.
o Sitting too close to a front airbag can
result in serious or fatal injury if the front
airbags inflate. Always sit as far back
from airbags as possible.
o Ignoring the SRS airbag warning light
can result in serious or fatal injury if the
airbags, occupant classification system
or pre-tensioners do not work properly.
Have your car checked by a dealer as soon
as possible if the SRS airbag warning
light alerts you to a potential problem.
o The SRS is designed to deploy the front
airbags only when an impact is suffi-
ciently severe and when the impact angle
is less than 30° from the forward longi-
tudinal axis of the vehicle. The front
airbags will not deploy in side, rear or
rollover impacts. Additionally, the
airbags will only deploy once. Seat belts
must be worn at all times.
!
WARNING:
o Modification to the seat structure can
adversely affect the seat track position
sensor and cause the airbag to deploy at
a different level than should be pro-
vided.
o Do not place any objects underneath the
front seats as they could damage the
seat track position sensor or interfere
with the occupant classification sys-
tem.
o 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.NOTE:o Be sure to read information about the
SRS on the labels provided on the back-
side of the sun visor and in the glove box.
o Advanced airbags are combined with
pre-tensioner seat belts to help provide
enhanced occupant protection in fron-
tal crashes. Front airbags are not in-
tended to deploy in collisions in which
sufficient protection can be provided by
the pre-tensioner seat belt.
o If you are considering modification of
your vehicle due to a disability, please
contact the Hyundai Customer Assis-
tance Center at 1-800-633-5151.

WARNING:
o No objects should be placed over or near
the airbag 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 airbags to deploy.
o If the airbags deploy, they must be re-
placed by an authorized Hyundai dealer.
o Do not tamper with or disconnect SRS
wiring or other components of the SRS
system. Doing so could result in injury,
due to accidental deployment of the
airbags or by rendering the SRS inopera-
tive.
o Even though your vehicle is equipped
with the occupant classification sys-
tem, do not install a child restraint sys-
tem 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 airbag deployment in case of an
accident.
o Do not allow children to ride in the front
passenger seat. If older children (teen-
agers and older) must ride in the front
seat, make sure they are always properly
belted and the seat is moved back as far
as possible.
o For maximum safety protection in all
types of crashes, all occupants includ-
ing the driver should always wear their
seat belts whether or not an airbag 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 unnecessarily close to the airbag
while the vehicle is in motion.
o Sitting improperly or out of position can
result in serious or fatal injury in a crash.
All occupants should sit 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 until the ve-
hicle is parked and the ignition key is
removed.
o The SRS airbag system must deploy very
rapidly to provide protection in a crash.
If an occupant is out of position because
of not wearing a seat belt, the airbag may
forcefully contact the occupant causing
serious or fatal injuries.

Upon deployment, tear seams molded directly
into the pad covers will separate under pres-
sure from the expansion of the airbags. Further
opening of the covers then allows full inflation of
the airbags.A fully inflated airbag, in combination 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 airbag immediately
starts deflating, enabling the driver to maintain
forward visibility and the ability to steer or
operate other controls.

14.Curtain Airbag Module
The SRSCM continually monitors all elements
while the ignition is "ON" to determine if a frontal
or near-frontal impact is severe enough to
require airbag deployment or pre-tensioner seat
belt deployment.
The SRS "AIRBAG" warning light on the instru-
ment panel will illuminate for about 6 seconds
after the ignition key is turned to the "ON"
position or after the engine is started, after which
the "AIRBAG" warning light should go out.The airbag modules are located both in the
center of the steering wheel and in the front
passenger's panel above the glove box. When
the SRSCM detects a sufficiently severe impact
to the front of the vehicle, it will automatically
deploy the front airbags.

o The SRS can function only when the
ignition key is in the "ON" position. If the
SRS "AIRBAG" warning light does not
illuminate, or continuously remains on
after illuminating for about 6 seconds
when the ignition key 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 inspect-
ed by your Hyundai dealer.
o Before you replace a fuse or disconnect
a battery terminal, turn the ignition key
to the "LOCK" position and remove the
ignition key. Never remove or replace the
airbag related fuse(s) when the ignition
key is in the "ON" position. Failure to
heed this warning will cause the SRS
"AIRBAG" warning light to illuminate. Passenger's Front Airbag
CAUTION:
o Do not install or place any accessories
(drink holder, cassette holder, sticker,
etc.) on the front passenger's panel
above the glove box in a vehicle with a
passenger's airbag. Such objects may
become dangerous projectiles and cause
injury if the passenger's airbag inflates.
o 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. If there is any
leakage from the air freshener onto these
areas (instrument cluster, instrument

panel or air ventilator), it may damage
these parts. If the liquid from the air
freshener does leak onto these areas,
wash them with water immediately.
WARNING:
o When the SRS is activated, there may be
a loud noise and fine dust will be re-
leased throughout the vehicle. These
conditions are normal and are not haz-
ardous. However, the fine dust generat-
ed during airbag deployment may cause
skin irritation. Wash all exposed skin
areas thoroughly with lukewarm water
and a mild soap after an accident in
which the airbags were deployed.
WARNING:
NOTE:
Your vehicle's Supplemental Restraint Sys-
tem Control Module is equipped a record-
ing device which may record the use of the
seat belt restraint system by the driver and
front passenger in certain collisions.
