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 electrical 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 prop-
erly. 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.

B100A01NF-AATSEAT WARMER (If Installed)The seat warmer is provided to warm the front
seats during cold weather. With the ignition key
in the "ON" position, push either of the switches
to warm the driver's seat or the front passenger's
seat.
During mild weather or under conditions where
the operation of the seat warmer is not needed,
keep the switches in the "OFF" position.NOTE:o The seat warmer may not operate if the
ambient temperature is warm.
o If the seat warmer doesn't operate when
the ambient temperature is lower than
75.2°F (24°C), it must be checked at an
authorized dealer.
B100A01NF
WARNING:
Do not turn on the seat warmers, if the seat
is occupied by someone who cannot moni-
tor the temperature and turn off the seat
warmer, if it becomes too warm. The seat
warmers should not be turned on when
children, the elderly, ill people, and sleep-
ing people occupy the seat.

On outboard rear seats
B235G02NF
On rear seat center positionTo install a child restraint system in the rear
seats, extend the shoulder/lap belt entirely from
its retractor until a "click" is felt. This will engage
the seat belt retractor automatic locking feature,
which allows the seat belt to retract but not
extend. Install the child restraint system, buckle
the seat belt and allow the seat belt to take up
any slack. Make sure that the lap portion of the
belt is tight around the child restraint system and
the shoulder portion of the belt is positioned so
that it cannot interfere with the child's head or
neck. Also, double check to be sure that the
retractor has engaged the Automatic Locking
feature by trying to extend webbing out of the
retractor. If the retractor is in the Automatic
Locking mode, the belt will be locked. After
installation of the child restraint system, try to
move it in all directions to be sure the child
restraint system is securely installed. If you need
to tighten the belt, pull more webbing toward the
retractor. When you unbuckle the seat belt and
allow it to retract, the retractor will automatically
revert back to its normal seated passenger
Emergency Locking usage condition.
!
WARNING:
o If the retractor is not in the Automatic
Locking mode, the child restraint can
move when your vehicle turns or stops
suddenly. A child can be seriously in-
jured or killed if the child restraint is not
properly anchored to the car, including
setting the retractor to the Automatic
Locking mode.
o Do not install any child restraint system
in the front passenger seat. Should an
accident occur and cause the passenger
side airbag to deploy, it could severely
injure or kill an infant or child seated in
an infant or child seat. Therefore, only
use a child restraint system in the rear
seat of your vehicle.NOTE:o Before installing the child restraint sys-
tem in any seating position, read the
instructions supplied by the child re-
straint system manufacturer.
o If the seat belt does not operate as de-
scribed, have the system checked imme-
diately by your authorized Hyundai dealer.

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 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.
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 thoroughly after
an accident in which the pre-tensioner
seat belts were activated.
WARNING:
!

BAG
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
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 work-
ing properly, this warning light will illu-
minate even if there is no malfunction of
the SRS airbag. If the SRS airbag warning
light does not illuminate when the igni-
tion key is turned to "ON", or if it blinks
for a second and remains illuminated
after illuminating 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 belt or 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 not to 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.

B990A02NF-AATOCCUPANT CLASSIFICATION SYSTEMYour vehicle is equipped with an occupant
classification system in the front passenger's
seat.
The Occupant Classification system is de-
signed to detect the presence of a properly-
seated front passenger and determine if the
passenger's front airbag should be enabled
(may inflate) or not. The driver's front airbag is
not affected or controlled by the Occupant
Classification system.
If the front passenger seat is occupied by a
person that the system determines to be of adult
size, and he/she sits properly (sitting upright
with the seatback in an upright position, cen-
tered on the seat cushion with their seat belt on,

!Always wash all exposed skin areas thor-
oughly with lukewarm water and a mild
soap after an accident in which the
airbags were deployed.
o The SRS can function only when the
ignition key is in the "ON" position. If the
SRS "AIRBAG" warning light does not
illuminate, or continuously remains on
after illuminating for about 6 seconds
when the ignition key is turned to the
"ON" position, or after the engine is
started, comes on while driving, the SRS
is not working properly. If this occurs,
have your vehicle immediately inspect-
ed by your Hyundai dealer.
o Before you replace a fuse or disconnect
a battery terminal, turn the ignition key
to the "LOCK" position and remove the
ignition key. Never remove or replace the
airbag related fuse(s) when the ignition
key is in the "ON" position. Failure to
heed this warning will cause the SRS
"AIRBAG" warning light to illuminate. 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 immediately.
WARNING:
o If an airbag deploys, there may be a loud
noise followed by a fine dust released in
the vehicle. These conditions are nor-
mal and are not hazardous - the airbags
are packed in this fine powder. The dust
generated during airbag deployment
may cause skin or eye irritation as well as
aggravate asthma for some persons.

cator will be turned off and the front passenger's
airbag will be able to inflate, if necessary, in
frontal crashes.
You will find the "PASSENGER AIR BAG OFF"
indicator on the center facia panel. This system
detects the conditions 1~4 in the following table
and activates or deactivates front passenger
airbags based on these conditions.
Condition and operation in the front pas-
senger occupant classification system*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 recognize
him/her as a child depending on his/her
physique and posture.
*2) Do not allow children to ride in the front
passenger seat. When a larger child who
has outgrown a child restraint system sits in
the front passenger seat, the system may
recognize him/her as an adult depending on
his/her physique or posture.
*3) Never install a child restraint system on the
front passenger seat.

WARNING:
o Do not modify or replace the front pas-
senger seat. Don't place anything on or
attach anything such as a blanket or
after market seat heater to the front
passenger seat. This can adversely af-
fect the occupant classification system.
o Do not sit on sharp objects such as tools
when occupying the front passenger
seat. This can adversely affect the occu-
pant classification system.
o Do not use accessory seat covers on the
front seats.
o Accident statistics show that children
are safer if they are restrained in the rear,
as opposed to the front seat. It is recom-
mended that child restraints be secured
in a rear seat, including an infant riding
in a rear-facing infant seat, a child riding
in a forward-facing child seat and an
older child riding in a booster seat.
o Airbags can only be used once – have an
authorized Hyundai dealer replace the
airbag immediately after deployment.
!
WARNING:
o A smaller-stature adult who is not seated
correctly (for example: seat excessively
reclined, leaning on the center console,
or hips shifted forward in the seat) can
cause a condition where the advanced
frontal airbag system senses less weight
than if the occupant were seated prop-
erly (sitting upright with the seatback in
an upright position, centered on the seat
cushion with their seat belt on, legs
comfortably extended and their feet on
the floor). This condition can result in an
adult potentially being misclassified and
illumination of the "PASSENGER AIR
BAG OFF" indicator.
B990B05Y-AATSide 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, 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.
