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 activated
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 com-
partment. These are normal operating
conditions and are not hazardous.
CAUTION:o The sensor that activates the SRS airbag
is connected with the pre-tensioner seat
belt. The SRS airbag warning light on
the instrument panel will blink for ap-
proximately 6 seconds after the ignition
key has been turned to the "ON" posi-
tion, and then it should turn off.
o If the pre-tensioner seat belt is not work-
ing properly, this warning light will illu-
minate even if there is no malfunction 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.
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 the seat belts when driving
or riding in a motor vehicle.
!
!WARNING:To obtain maximum benefit from a pre-
tensioner seat belt:
1. The seat belt must be worn correctly.
2. The seat belt must be adjusted to the
correct position.
3. Be sure you and your passengers always
wear seat belts and wear then properly.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.

ADVANCED SUPPLEMENTAL
RESTRAINT (AIRBAG) SYSTEM (SRS)
B240A01E-AAT
Your 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 thanthat offered by the seat belt system alone, in
case of a frontal impact of sufficient severity.
The advanced 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 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'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,
and how severe is impact.
The advanced airbags offer the ability to control
the airbag inflation with two pressure levels. A
first stage pressure level is provided for mod-
erate-severity impacts. A second stage pres-
sure level is provided for more severe impacts.
Your Hyundai is equipped with an Occupant
Classification
® system in the front passenger's
seat. The Occupant Classification® system de-
tects the presence of a passenger in the front
passenger's seat and will turn off the front
passenger's airbag under certain conditions.
For more detail, see page 1-37.
B240A01E
Driver's AirbagCAUTION: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 is con-
nected with the seat position sensor. If the
SRS airbag warning light does not illumi-
nate when the ignition key is turned to the
"ON" position, if it remains illuminated after
blinking for approximately 6 seconds, or if
it illuminates while the vehicle is being
driven, have an authorized Hyundai dealer
inspect the seat position sensor and the
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 pressure level than should be
provided.
o Do not place any objects that may cause
magnetic fields near the front seat. These
can cause a malfunction of the seat
position sensor.

!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.

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
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 or front seats must be
performed by a qualified Hyundai technician.
Improper handling of the airbag system may
result in serious personal injury.!
o For best protection from the side impact
airbag system and to avoid being injured
by the deploying side impact airbag,
both front seat occupants should sit in
an upright position with their feet on the
floor and 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 prevent
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.
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:
WARNING:o The side impact airbag is supplemental
to the driver's and the passenger's seat
belt systems and is not a substitute for
them. Therefore your seat belts must be
worn at all times while the vehicle is in
motion. The airbags deploy only in cer-
tain side impact conditions severe
enough to cause significant injury to the
vehicle occupants.
