VEHICLE DATA COLLECTION
AND EVENT DATA
RECORDERS
This vehicle is equipped with an event
data recorder (EDR). The main purpose
of an EDR is to record, in certain crash
or near crash-like situations, such as
an air bag deployment or hitting a
road obstacle, data that will assist in
understanding how a vehicle’s systems
performed. The EDR is designed to
record data related to vehicle dynamics
and safety systems for a short period of
time, typically 30 seconds or less. The
EDR in this vehicle is designed to record
such data as:
• How various systems in your vehicle
were operating;
• Whether or not the driver and
passenger safety belts were buckled/
fastened;
• How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
• How fast the vehicle was traveling.
This data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. NOTE:
EDR data is recorded by your vehicle
only if a non-trivial crash situation
occurs; no data is recorded by the EDR
under normal driving conditions and
no personal data (e.g., name, gender,
age, and crash location) are recorded.
However, other parties, such as law
enforcement, could combine the
EDR data with the type of personally
identifying data routinely acquired
during a crash investigation.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such as
law enforcement, that have the special
equipment, can read the information if
they have access to the vehicle or the
EDR.

This chapter provides you with important information about how to protect yourself and your
passengers. It explains how to properly use your seats and seat belts, and how your air bags work.
Additionally, this chapter explains how to properly restrain infants and children in your vehicle.

Seats & Safety System3-2
You will find many safety precautions
and recommendations throughout this
section, and throughout this manual.
The safety precautions in this section are
among the most important.
Always Wear Your Seat Belt
A seat belt is your best protection in all
types of accidents. Air bags are designed
to supplement seat belts, not replace
them. So even though your vehicle is
equipped with air bags, ALWAYS make
sure you and your passengers wear your
seat belts, and wear them properly.
Restrain All Children
All children under age 13 should ride
in your vehicle properly restrained in a
rear seat, not the front seat. Infants and
small children should be restrained in
an appropriate child restraint. Larger
children should use a booster seat with
the lap/shoulder belt until they can use
the seat belt properly without a booster
seat.
Air Bag Hazards
While air bags can save lives, they can
also cause serious or fatal injuries to
occupants who sit too close to them, or
who are not properly restrained. Infants,
young children, and shorter adults are at
the greatest risk of being injured by an
inflating air bag. Follow all instructions
and warnings in this manual.
Driver Distraction
Driver distraction presents a serious and
potentially deadly danger, especially for
inexperienced drivers. Safety should be
the first concern when behind the wheel,
and drivers need to be aware of the wide
array of potential distractions, such as
drowsiness, reaching for objects, eating,
personal grooming, other passengers,
and using cellular phones. Drivers can become distracted when
they take their eyes and attention off
the road or their hands off the wheel to
focus on activities other than driving. To
reduce your risk of distraction or getting
into an accident:
• ALWAYS set up your mobile devices
(i.e., MP3 players, phones, navigation
units, etc.) when your vehicle is
parked or safely stopped.
• ONLY use your mobile device when allowed by laws and when conditions
permit safe use. NEVER text or email
while driving. Most states have laws
prohibiting drivers from texting. Some
states and cities also prohibit drivers
from using handheld phones.
• NEVER let the use of a mobile device distract you from driving. You have a
responsibility to your passengers and
others on the road to always drive
safely, with your hands on the wheel
as well as your eyes and attention on
the road.
Control Your Speed
Excessive speed is a major factor in crash
injuries and deaths. Generally, the higher
the speed, the greater the risk, but
serious injuries can also occur at lower
speeds. Never drive faster than is safe
for current conditions, regardless of the
maximum speed posted.
Keep Your Vehicle in Safe
Condition
Having a tire blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such problems,
check your tire pressures and condition
frequently, and perform all regularly
scheduled maintenance.
IMPORTANT SAFETY PRECAUTIONS

OHI038175LOHI038175L
The Pre-Tensioner Seat Belt System
consists mainly of the following
components. Their locations are shown
in the illustration above:
1. SRS air bag warning light
2. Retractor pre-tensioner
3. SRS control module
NOTICE
The sensor that activates the SRS air
bag is connected with the pre-tensioner
seat belts. The SRS air bag warning light
on the instrument panel will illuminate
for approximately 6 seconds after the
ignition switch is in the ON position,
and then it should turn off.
If the pre-tensioner is not working
properly, the warning light will
illuminate even if the SRS air bag is not
malfunctioning. If the warning light
does not illuminate, stays illuminated
or illuminates when the vehicle is being
driven, have an authorized HYUNDAI
dealer inspect the pre-tensioner seat
belts and SRS air bags as soon as
possible.
NOTICE
• Both the driver’s and front
passenger’s pre-tensioner seat belts
may be activated in certain frontal or
side collisions or rollovers.
• 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.
• Although it is non-toxic, the fine
dust may cause skin irritation and
should not be inhaled for prolonged
periods. Wash all exposed skin areas
thoroughly after an accident in
which the pre-tensioner seat belts
were activated.
WARNING
• Fasten your seat belt while sitting
properly in an upright position to
maximize the effectiveness of the
pre-tensioner seat belt system.
• A pre-tensioner seat belt system
is designed to activate only once.
Replace the pre-tensioner seat belt
system, if it was activated in an
accident.

3. Check that the child restraint is securely attached to the seat by
pushing and pulling the seat forward-
and-back and side-to-side.
Securing a child restraint with lap/
shoulder belt
When not using the LATCH system, all
child restraints must be secured to a
vehicle rear seat with the lap part of a
lap/shoulder belt.
WARNING
ALWAYS place a rear-facing child
restraint in the rear seat of the vehicle.
Placing a rear-facing child restraint in
the front seat can result in serious injury
or death if the child restraint is struck
by an inflating air bag.
OHI038145OHI038145
Automatic locking mode
Since all passenger seat belts move
fr
eely under normal conditions and
only lock under extreme or emergency
conditions (emergency locking mode),
you must manually pull the seat belt all
the way out to shift the retractor to the
“Automatic Locking” mode to secure a
child restraint.
The “Automatic Locking” mode will
help prevent the normal movement of
the child in the vehicle from causing
the seat belt to loosen and compromise
the child restraint system. To secure a
child restraint system, use the following
procedure. To install a child restraint system on the
rear seats, do the following:
1. Place the child restraint system on a
rear seat and route the lap/ shoulder
belt around or through the child
restraint, following the restraint
manufacturer’s instructions. Be sure
the seat belt webbing is not twisted.
Information
When using the rear center seat belt, you
should also refer to the “Rear Seat Belt –
Passenger’s 3-point system” section in this
chapter.
OHI038146OHI038146
2. Fasten the lap/shoulder belt latch into the buckle. Listen for the distinct
“click” sound.

SRS warning light
The SRS (Supplement Restraint System)
air bag w
arning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential malfunction with your
air bag system, which could include your
side and curtain air bags used for rollover
protection.
WARNING
If your SRS malfunctions, the air bag
may not inflate properly during an
accident increasing the risk of serious
injury or death.
If any of the following conditions occur,
your SRS is malfunctioning:
• The light does not turn on for
approximately six seconds when the
Engine Start/Stop button is in the ON
position.
• The light stays on after illuminating
for approximately six seconds.
• The light comes on while the vehicle
is in motion.
• The light blinks when the engine is
running.
Have an authorized HYUNDAI dealer
inspect the SRS as soon as possible if
any of these conditions occur. During a frontal collision, sensors will
detect the vehicle’s deceleration. If the
rate of deceleration is high enough, the
control unit will inflate the front air bags.
The front air bags help protect the driver
and front passenger by responding to
frontal impacts in which seat belts alone
cannot provide adequate restraint. When
needed, the side air bags help provide
protection in the event of a side impact
or rollover.
• Air bags are activated (able to inflate
if necessary) when the Engine Start/
Stop button is in the ON position or
approximately within 3 minutes after
ignition off.
• Air bags inflate in the event of certain frontal or side collisions to help
protect the occupants from serious
physical injury.
• Generally, air bags are designed to inflate based upon the severity of
a collision, its direction, etc. These
two factors determine whether
the sensors produce an electronic
deployment/inflation signal.
• The front air bags will completely inflate and deflate in an instant. It is
virtually impossible for you to see the
air bags inflate during an accident. It is
much more likely that you will simply
see the deflated air bags hanging out
of their storage compartments after
the collision.
