WARNING:
o Pre-tensioners are designed to operate
only one time. After activation, pre-
tensioner seat belts must be replaced.
All seat belts, of any type, should always
be replaced after they have been worn
during a collision.
o The pre-tensioner seat belt assembly
mechanisms become hot during activa-
tion. Do not touch the pre-tensioner seat
belt assemblies for several minutes after
they have been activated.
o Do not attempt to inspect or replace the
pre-tensioner seat belts yourself. This
must be done by an authorized Hyundai
dealer.
o Do not strike the pre-tensioner seat belt
assemblies.
o Do not attempt to service or repair the
pre-tensioner seat belt system in any
manner.
o Improper handling of the pre-tensioner
seat belt assemblies, and failure to heed
the warnings to not strike, modify, in-
spect, replace, service or repair the pre-
tensioner seat belt assemblies may lead
to improper operation or inadvertent
activation and serious injury.
o Always wear seat belts when driving or
riding in a motor vehicle.
ADVANCED SUPPLEMENTAL
RESTRAINT (AIRBAG) SYSTEM (SRS)B240A01E-AATYour 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.The SRS uses a collection of 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 sever-
ity.
The driver's and front passenger's seat position
sensors, which are installed on the seat track,
determine if the seats are fore or aft of a
reference position. Similarly, the seat belt usage
sensors 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 is the impact.
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 the seat position sensor is not working
properly, the SRS airbag warning light on
the instrument panel will illuminate even if
there is no malfunction of the SRS airbag
system, because the SRS airbag warning
light is connected with the seat position
sensor. If the SRS airbag warning light does
not illuminate when the ignition key is
turned to the "ON" position, if it remains
illuminated after coming on for approxi-
mately 6 seconds, or if it illuminates while
the vehicle is being driven, have an autho-
rized Hyundai dealer inspect the seat posi-
tion sensor and the advanced SRS airbag
system as soon as possible.
!
WARNING:
o Modification to the seat structure can
adversely affect the seat position sensor
and cause the airbag to deploy at a
different level than should be provided.
o Do not place any objects underneath the
front seats which could damage the seat
position sensor or interfere with the
occupant classification system.
o Do not place any objects that may cause
magnetic fields near the front seats.
These may cause a malfunction of the
seat 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 light collisions in
which 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.
AIR
BAG
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.
!
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 injury 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 indicator light can re-
sult 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 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.

Side Impact
Rollover
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, airbags will not
deploy in frontal crashes below the de-
ployment threshold.
!
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 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 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 in their
seats with their feet on the floor until the
vehicle 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.
!

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 service reminder indicator (SRI) on
the instrument 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 SRI 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.

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.
B240B02L

1FEATURES OF YOUR HYUNDAI34
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.
!
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.
CAUTION:
When installing a container of liquid air
freshener inside the vehicle, do not place it
near the instrument cluster nor on the in-
strument panel surface. If there is any leak-
age 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 immedi-
ately.

o The SRS can function only when the
ignition key is in the "ON" position. If the
SRS SRI does not illuminate or contin-
uously remains on after illuminating for
about 6 seconds when the ignition key
is turned to the "ON" position, or after
the engine is started, illuminates while
driving, the SRS is not working properly.
If this occurs, have your vehicle immedi-
ately inspected by your Hyundai dealer.
o Before you replace a fuse or disconnect
a battery terminal, turn the ignition key
to the "LOCK" position or remove the
ignition key. Never remove or replace the
air bag related fuse(s) when the ignition
key is in the "ON" position. Failure to
heed this warning will cause the SRS SRI
to illuminate.
WARNING:
B990A01JM-AATOCCUPANT CLASSIFICATION SYSTEMIf your instrument panel has the indicator pic-
tured in the following illustration, your vehicle
has an occupant classification system.
The indicator will be visible when you turn the
ignition key to START or RUN. The words
"PASSENGER AIR BAG OFF" will be visible on
the instrument panel during the system check.
When the system check is complete, the pas-
senger sensing system will turn off the right front
passenger's frontal air bag under certain con-
ditions. The driver's air bag and the side impact
air bags are not affected by the occupant
classification system.
B990A01JM
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.The occupant classification system works with
sensors that are part of the right front
passenger's seat and seat belt. The sensors
are designed to detect the presence of a prop-
erly-seated occupant and determine if the
passenger's frontal air bag should be
enabled(may inflate) or not.
!
WARNING:
o A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger's air bag inflates.
o The safest place for children is in the rear
seat. Rearward and forward facing child
restraint and booster seats must only be
used in the rear seat.
o Children under the age of 13 must al-
ways ride in the rear seat, properly re-
strained in child restraints or with the
vehicle seat belts, depending upon their
size.NOTE:Many times an indicator light is a sign that
there is a need for service. In the case of the
occupant classification system indicator, it
does not mean there is a need for service.
It informs the occupants of the status of the
right front passenger's airbag on or off.

1FEATURES OF YOUR HYUNDAI36
!
The occupant classification system is designed
to enable(may inflate) the right front passenger's
frontal air bag anytime the system senses that
a person of adult size is sitting properly in the
right front passenger's seat. When the passen-
ger sensing system has allowed the air bag to
be enabled, the indicator will turn off and stay
turned off to remind you that the air bag is active.
For some children who have outgrown child
restraints and for very small adults, the occu-
pant classification system may or may not turn
off the right front passenger's frontal air bag,
depending upon the person's seating posture
and body build.
If a person of adult-size is sitting in the right front
passenger's seat, but the indicator is turned on,
it could be because that person isn't sitting
properly in the seat. The right front passenger
should sit upright, centered on the seat cushion,
with their seat belt on and legs comfortably
extended, feet on the floor, and with the seat in
an upright position.
Aftermarket equipment, such as seat covers,
can affect how the occupant classification sys-
tem operates. Do not use seat covers or other
aftermarket equipment if your vehicle has the
occupant classification system.
!
B990B02JM-AATPassenger Air Bag Status IndicatorIf your vehicle has the occupant classification
system, your instrument panel will have a pas-
senger air bag status indicator.
When the ignition key is turned to RUN or
START, the passenger air bag status indicator
will be turned on and off for several seconds as
a system check. Then, after several more
seconds, the status indicator will be turned on
or off to let you know the status of the right front
passenger's frontal air bag.
If the "PASSENGER AIR BAG OFF" indicator is
illuminated, it means that the right front
passenger's frontal air bag is disabled. If the
indicator is not illuminated, it means that the right
front passenger's frontal air bag is enabled.

CAUTION:
Stowing of articles under the passenger's
seat or between the passenger's seat cush-
ion and seatback may interfere with the
proper operation of the occupant classifi-
cation system.
WARNING
Everyone in your vehicle should wear a
safety belt properly -- whether or not
there is an air bag for that person.

The occupant classification system can func-
tion only when the ignition key is in the "ON"
position. If the "PASSENGER AIR BAG OFF"
indicator is illuminated when the front
passenger's seat is occupied by an adult who
is seated properly sitting upright and with the
seat in an upright position, centered on the seat
cushion, with their seat belt on and legs comfort-
ably extended feet on the floor, have your
vehicle immediately inspected by your Hyundai
dealer.

WARNING:
o A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger's air bag inflates. Don't
use a rear-facing child restraint in the
right front passenger's seat.
o If the indicator and the air bag readiness
light ever illuminate at the same time, it
means that something may be wrong
with the air bag system. If this ever
happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger seat
may not have the supplemental protec-
tion of the frontal air bag.
o If the occupant classification system is
not working properly, the SRS airbag
warning light on the instrument panel
will illuminate because the passenger's
airbag is connected with the occupant
classification system.
o If there is a malfunction of the occupant
classification system, the "PASSENGER
AIR BAG" indicator will illuminate and
the front passenger's airbag will not
deploy in frontal crashes.
!
WARNING:
o If the SRS airbag warning light does not
illuminate when the ignition key is turned
to "ON" position, if it remains illumi-
nated after coming on for approximately
6 seconds, have an authorized Hyundai
dealer inspect the occupant classifica-
tion system with the SRS airbag system
as soon as possible.
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's seat. The
infant or child could be severely injured
or killed by an airbag deployment in case
of an accident. A child restraint system
must never be placed in the front seat.
Children who are too large for child
restraint systems should always occupy
the rear seat and use the available lap/
shoulder belts. Children are afforded the
most safety in the event of an accident
when they are restrained by a proper
restraint system in the rear seat. *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 detect him/
her as a child depending on his/her physique
and posture.*2) When a larger child who has outgrown a child
restraint system sits in the passenger seat,
the system may detect him/her as an adult
depending on his/her physique and posture.

WARNING:
o The occupant classification system can
function only when the ignition key is in
the "ON" position. If the "PASSENGER
AIR BAG OFF" indicator is illuminated
when the front passenger's seat is occu-
pied by an adult who is seated properly
(sitting upright with the seat in an up-
right position, centered on the seat cush-
ion, with the person's legs comfortably
extended, and feet on the floor), have
your vehicle immediately inspected by
your Hyundai dealer.
o If luggage or other objects are placed on
the front passenger's seat, the "Passen-
ger Airbag Off" indicator may be illumi-
nated. These conditions do not indicate
a problem.
o If an adult front seat passenger changes
their seating position(for example, not
sitting upright, sitting slouched , sitting
with legs spread, or otherwise being out
of position), the "PASSENGER AIR BAG
OFF" indicator may illuminate, and the
passenger's airbag may illuminate not
deploy in a collision. Always be sure to
sit properly in the front passenger seat
and wear the seat belt properly.o Do not modify or replace the front pas-
senger seat. Don't place or attach any-
thing on the front passenger seat. This
can adversely affect the occupant clas-
sification system.
o Do not install accessory seat covers on
the front passenger seats.
B990B01JM-AATSide Impact AirbagYour Hyundai is equipped with a side impact
airbag in each front seat. The purpose of the
airbag is to provide the vehicle's driver and/or
the front passenger with additional protection
than that offered by the seat belt alone. The side
impact airbags are designed to deploy only
during certain side-impact collisions, depend-
ing on the crash severity, angle, speed and point
of impact. The side impact airbags are not
designed to deploy in all side impact situations.

dangerous projectiles and cause injury
if the supplemental side impact air bag
inflates.
o To prevent unexpected deployment of
the side impact air bag that may result in
personal injury, avoid impact to the side
airbag sensor when the ignition key is on.
B990C01LZ-GATCurtain AirbagCurtain airbags are located along both sides of
the roof rails above the front and rear doors.
They are designed to help protect the heads of
the front seat occupants and the rear outboard
seat occupants in certain side impact collisions.
The curtain airbags are designed to deploy only
during certain side impact collisions, depending
on the crash severity, angle, speed and impact.
The curtain airbags are not designed to deploy
in all side impact situations, collisions from the
front or rear of the vehicle or in most rollover
situations.
