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:
Riding with a reclined seatback
increases your chance of serious or
fatal injuries in the event of a collision or
sudden stop. The protection of your
restraint system (seat belts and airbags)
is greatly reduced by reclining your seat.
Seat belts must be snug against your
hips and chest to work properly. The
more the seatback is reclined, the greater
the chance that an occupant's hips will
slide under the lap belt or the occupant's
neck will strike the shoulder belt. Drivers
and passengers should always sit well
back in their seats, properly belted, and
with the seatbacks upright.
B080D02JM-AATAdjustable HeadrestsHeadrests are designed to help reduce
the risk of neck injuries.
To raise the headrest, pull it up. To lower
the headrest, push it down while pressing
the lock knob. To remove the headrest,
raise it as far as it can go then press the lock
knob while pulling upward. This should
only be done when the seat is not occupied.

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.

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 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
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
position 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
occupant classification system is not
working properly, the SRS airbag warning
light
on the instrument panel will
illuminate because the SRS airbag
warning light is connected with the seat
track position sensor and the occupant
classification system. If the SRS airbag
warning light does not illuminate when
the ignition key is turned to the "ON"
position, remains illuminated after
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 conditions. For more
detail, see "Occupant Classification
System" later in this section.
B240A03NF-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

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.

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.
