!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 dur-
ing 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 acti-
vation and serious injury.
o Always wear the seat belts when driving
or riding in a motor vehicle.CAUTION:o Because the sensor that activates the
SRS airbag is connected with the pre-
tensioner seat belt, the SRS airbag warn-
ing light on the instrument panel will
blink for approximately 6 seconds after
the ignition key has been turned to the
"ON" position, and then it should turn
off.
o If the pre-tensioner seat belt is not
working properly, this warning light
will illuminate even if there is no mal-
function of the SRS airbag system.
If the SRS airbag warning light does not
illuminate when the ignition key is turned
to "ON", or if it remains illuminated after
blinking for approximately 6 seconds, or
if it illuminates while the vehicle is being
driven, please have an authorized Hyundai
dealer inspect the pre-tensioner seat
belts and SRS airbag system as soon as
possible.
!
NOTE:o Both the driver's and front passenger's
pre-tensioner seat belts will be activated
in certain frontal collisions. The pre-
tensioner seat belts can be activated
alone or, where the frontal collision is
severe enough, together with the
airbags.
The pre-tensioners will not be acti-
vated if the seat belts are not being
worn at the time of the collision.
o When the pre-tensioner seat belts are
activated, a loud noise may be heard and
fine dust, which may appear to be smoke,
may be visible in the passenger compart-
ment. These are normal operating condi-
tions and are not hazardous.
o Although it is harmless, the fine dust may
cause skin irritation and should not be
breathed for prolonged periods. Wash
your hands and face thoroughly after an
accident in which the pre-tensioner seat
belts were activated.

29DUAL-STAGE SUPPLEMENTAL
RESTRAINT (AIRBAG) SYSTEM (SRS)
B240A01A-AAT
Your Hyundai is equipped with a Dual-stage
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 steer-
ing 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.
B240A03A
Driver's AirbagThe dual-stage SRS uses a collection of sen-
sors 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 posi-
tion sensors 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's pressure based on how
close the driver's seat is to the steering wheel,
how close the passenger's seat is to the
instrument panel and whether or not the seat
belts are fastened.
The dual-stage airbags offer the ability to control
the airbag inflation with two pressure levels. A
lower pressure level is provided for moderate-
severity impacts. A higher-pressure level is pro-
vided for more severe impacts.
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.
WARNING:o As its name implies, the SRS is de-
signed to work with, and be supple-
mental to, the driver's and the
passenger's three point seat belt sys-
tems and is not a substitute for them.
Therefore, your seat belts must be worn
at all times while the vehicle is in mo-
tion. The airbags deploy only in certain
frontal impact conditions severe
enough to cause significant injury to
the vehicle occupants.
o The SRS is designed to deploy the
airbags only when an impact is suffi-
ciently severe and when the impact
angle is less than 30° from the forward
longitudinal axis of the vehicle and will
not deploy in side, rear or rollover im-
pacts. Additionally, the airbags will only
deploy once. Thus, seat belts must be
worn at all times.
!
o Dual-stage inflating airbags are com-
bined with pre-tensioner seat belts to
help provided enhanced occupant pro-
tection in frontal crashes. Front airbags
are not intended to deploy in light
collisions in which protection can be
provided by the pre-tensioner seat belt.

The SRSCM continually monitors all elements
while the ignition is "ON" to determine if a frontal
or near-frontal impact is severe enough to re-
quire airbag deployment.
The SRS service reminder indicator (SRI) on
the instrument panel will blink 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 considerable impact to
the front of the vehicle, it will automatically
deploy the airbags.
A fully inflated airbag in combination with a
properly worn seat belt slows the driver's or
the passenger's forward motion, thus reduc-
ing the risk of head and chest injury.
After complete inflation, the airbag immediately
starts deflating, enabling the driver to maintain
forward visibility.

Upon deployment, tear seams molded directly
into the pad covers will separate under pres-
sure from the expansion of the airbags. Fur-
ther opening of the covers then allows full
inflation of the airbags.

WARNING:o For best protection from the side im-
pact airbag system and to avoid being
injured by the deploying side impact
airbag, both front 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
o'clock positions.
The passenger's arms and hands should
be placed on their laps.
o Do not use any accessory seat covers.
o Use of seat covers could reduce or pre-
vent the effectiveness of the system.
o Do not install any accessories on the side
or near the side impact airbag.
o Do not use excessive force on the side of
the seat.
o Do not place any objects over the airbag
or between the airbag and yourself.
o Do not place any objects (an umbrella,
bag, etc.) between the front door and the
front seat. Such objects may become dan-
gerous projectiles and cause injury if the
supplemental side impact airbag inflates.

Side airbag
sensor
WARNING:o The side impact airbag is supplemental to
the driver's and the passenger's three
point seat belt systems and is not a sub-
stitute for them. Therefore your seat belts
must be worn at all times while the ve-
hicle is in motion. The airbags deploy
only in certain side impact conditions
severe enough to cause significant injury
to the vehicle occupants.
B990B04Y-GAT
Side Impact Airbag (If Installed)
Your 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, depending
on the crash severity, angle, speed and point of
impact. The side impact airbags are not de-
signed to deploy in all side impact situations.

!!WARNING: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
baby could be severely injured by an
airbag deployment in case of an accident.
o Modification to SRS components or wir-
ing, including the addition of any kind of
badges to the pad covers or modifica-
tions to the body structure, can adversely
affect SRS performance and lead to pos-
sible injury.
o For cleaning the airbag pad covers, use
only a soft, dry cloth or one which has
been moistened with plain water. Sol-
vents or cleaners could adversely affect
the airbag covers and proper deployment
of the system.
o No objects should be placed over or near
the airbag modules on the steering wheel,
instrument panel, and the front passen-
ger'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 inflate.
o If the airbags inflate, they must be re-
placed by an authorized Hyundai dealer.
B240C01A-AAT
SRS Care
o The SRS is virtually maintenance free and
there are no parts you can safely service by
yourself. The entire SRS system must be
inspected by an authorized Hyundai dealer
in 10 years after the date that the vehicle
was manufactured.
o Any work on the SRS system, such as
removing, installing, repairing, or any work
on the steering wheel must be performed by
a qualified Hyundai technician. Improper han-
dling of the airbag system may result in
serious personal injury.
HSM393
o To prevent unexpected deployment of
the side impact air bag that may result
in personal injury, avoid impact to the
side impact airbag sensor when the
ignition key is on.WARNING:
