VEHICLE DATA COLLECTION AND EVENT DATA RECORDERS
Your Hyundai vehicle is equipped with many high technology, electronically controlled systems
that help to ensure your vehicle operates properly and provides the performance that you
expect. These systems utilize computers to monitor the operation of various systems and
components and help to control their operation. These computerized system operations are
wide-ranging and involve components to reduce emissions, to continuously evaluate the
readiness of the airbag and seat belt pretensioner systems, to determine when the airbag and
seat belt pre-tensioner systems should be deployed and then to activate the deployment, and
if equipped, to operate anti-lock braking, traction control and electronic stability control to assist
the driver to control the vehicle in difficult driving situations. These systems electronically store
information that is useful to service technicians when they need to diagnose and repair these
systems. Additional information is stored only when a crash occurs that results in the
deployment of the airbags or seat belt pre-tensioners. This type of data storage is done by
devices called event data recorders(EDR).
After a crash event, the airbag and seat belt pre-tensioner computer system, known as the
Supplemental Restraint System Control Module (SRSCM) or Airbag Control Unit (ACU), may
record some information about the condition of the vehicle and how it was being operated. This
information consists of data related to seat belt usage and if there was diagnostic information
in the airbag or seat belt systems at the time that a crash occurred, and if the ACU sensed that
a crash of sufficient severity occurred to require seat belt pre-tensioner or airbag deployment.
To retrieve this information, special equipment is needed and access to the vehicle or the device
that stores the data is required. Hyundai will not access information about a crash event or share
it with others except:
o in response to an official request of police or similar government office, or
o with the consent of the vehicle owner or, if the vehicle is leased, with the consent of the lessee,
or
o as part of Hyundai’s defense of litigation, or
o as required by law.

WARNING:
To obtain maximum benefit from a pre-
tensioner seat belt:
o The seatbelt must be worn correctly and
adjusted to the proper position (see
pages 1-23 and 1-26). Please read and
follow all of the important information
and precautions about your vehicle’s
occupant safety features – including
seat belts and advanced airbags – that
are provided in this manual.
!
CAUTION:
Do not put anything near the buckle.
Placing objects near the buckle can ad-
versely affect the buckle pre-tensioner
and may increase the risk of personal
injury in the event of a collision.
If the system senses excessive seat belt
tension on the driver or passenger's seat
belt when the pre-tensioner activates, the
load limiter inside the pre-tensioner will
release some of the pressure on the
affected seat belt.
The seat belt pre-tensioner system consists
mainly of the following components. Their
locations are shown in the illustration:
B180B02NF-AATPre-tensioner Seat BeltYour Hyundai vehicle is equipped with
driver's and front passenger's pre-tensioner
seat belts. The purpose of the pre-tensioner
is to make sure that the seat belts fit tightly
against the occupant's body 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.
When the vehicle stops suddenly, or if the
occupant tries to lean forward too quickly,
the seat belt retractor will lock into position.
In certain frontal collisions, the pre-
tensioner will activate and pull the seat belt
into tighter contact against the occupant's
body. The buckle pre-tensioner (which is
installed in the buckle) will also pull the
seat belt into the buckle.

!
o Be sure you and your passengers
always wear seat belts and wear them
properly.NOTE:o Both the driver's and front
passenger's pre-tensioner seat belts
will be activated in certain frontal col-
lisions. 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 compartment. These are
normal operating conditions 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 all exposed skin areas thor-
oughly after an accident in which the
pre-tensioner seat belts were acti-
vated.
WARNING:
!
CAUTION:
o Because 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 illuminate 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
malfunction of the SRS airbag. If the
SRS airbag warning light does not
illuminate when the ignition key is
turned to "ON", or if it blinks for a
second and remains illuminated after
illuminating for approximately 6 sec-
onds, or if it illuminates while the ve-
hicle is being driven, please have an
authorized Hyundai dealer inspect the
pre-tensioner seat belt or SRS airbag
system as soon as possible.
!
WARNING:
o Pre-tensioners are designed to oper-
ate only one time. After activation,
pre-tensioner seat belts must be re-
placed. 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 acti-
vation. Do not touch the pre-tensioner
seat belt assemblies for several min-
utes 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 not to strike, modify,
inspect, 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 driv-
ing or riding in a motor vehicle.

WARNING:
Always use seat belts and child restraints
– every trip, every time, everyone!
Airbags inflate with considerable force
and in the blink of an eye. Seat belts help
keep occupants in proper position to
obtain maximum benefit from the airbag.
Even with advanced airbags, improperly
belted and unbelted occupants can be
severely injured when the airbag inflates.
Always follow the precautions about seat
belts, airbags and occupant safety
contained in this manual.
To reduce the chance of serious or fatal
injuries and receive the maximum safety
benefit from your restraint system:
o Never place a child in any child or
booster seat in the front seat (see
child restraints 1-26).
o ABC – Always Buckle Children in the
back seat. It is the safest place for
children of any age to ride.
o Front and side impact airbags can
injure occupants improperly
positioned in the front seats.
o Move your seat as far back as
practical from the front airbags, while
still maintaining control of the vehicle.
o Never sit or lean unnecessarily close
to the front or side airbags.
!
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 system.
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.
o Advanced airbags are combined with
pre-tensioner seat belts to help provide
enhanced occupant protection in frontal
crashes. Front airbags are not intended
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.o Never lean against the door or center
console – always sit in an upright posi-
tion.
o Do not allow an adult passenger to ride
in the front seat when the “Passenger
Airbag OFF” indicator is illuminated,
because the airbag will not deploy in the
event of a moderate or severe frontal
crash.
o Never place objects over or near any
airbag module (front or side impact
airbags), because these objects can
injure passengers in a crash.
o Never place covers, blankets or after-
market seat warmers on the passenger
seat as these may interfere with the
occupant classification system.
o Do not tamper or disconnect SRS wiring
or other components. Injuries could
result from inadvertent deployment or
failure of the airbag to deploy in a crash.
o If the SRS airbag warning light (see pg
1-50) remains illuminated while the
vehicle is being driven, have an
authorized Hyundai dealer inspect the
airbag system as soon as possible.
o Airbags can only be used once – have
an authorized Hyundai dealer replace
the airbag immediately after
deployment.
WARNING:

1FEATURES OF YOUR HYUNDAI38
12. Side Impact Airbag Module
13. 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 in-
strument 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.
!
WARNING:
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 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 oc-
cupant causing serious or fatal
injuries.

Drive belts should be checked periodi-
cally for proper tension. At the same time,
belts should be examined for cracks, wear,
fraying or other evidence of deterioration
and replaced if necessary.
When a new belt is replaced, the belt
should be located within the pulley of flat
idler.
Belt routing should also be checked to be
sure there is no interference between the
belts and other parts of the engine.NOTE:Drive belt tension is adjusted automati-
cally by the auto tensioner.
CHECKING AND REPLACING
FUSESG200A01A-AATReplacing a Fusible LinkA fusible link will melt if the electrical circuits
from the battery are ever overloaded, thus
preventing damage to the entire wiring
harness. (This could be caused by a short
in the system drawing too much current.) If
this ever happens, have a Hyundai dealer
determine the cause, repair the system
and replace the fusible link. The fusible
links are located in a relay box in the
engine compartment for easy inspection.
