ed warranties covering the vehicle. Certain modifi-
cations may also be in violation of regulations
established by the U.S. Department of
Transportation and other federal or state agencies.
Your vehicle is equipped with electronic fuel injec-
tion and other electronic components. It is possible
for an improperly installed/adjusted two-way radio
or cellular telephone to adversely affect electronic
systems. For this reason, we recommend that you
carefully follow the radio manufacturer’s instructions

Introduction
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 sys-
tems for a short period of time,
typically 30 seconds or less. The
EDR in this vehicle is designed to
record such data as:
vehicle were operating;
passenger safety belts were
buckled/fastened;
depressing the accelerator
and/or brake pedal; and,
ing. These data can help provide a bet-
ter understanding of the circum-
stances in which crashes and
injuries occur. NOTE: EDR data
are recorded by your vehicle only
if a non-trivial crash situation
occurs; no data are 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 per-
sonally identifying data routinely
acquired during a crash investiga-
tion.
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.

Safety system of your vehicle
• ALWAYS set up your mobile devices(i.e., MP3 players, phones, naviga-
tion 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 passen-
gers 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 condi-
tions, 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 prob-
lems, check your tire pressures and
condition frequently, and perform all
regularly scheduled maintenance.

While the engine is running, push the
switch to cool the driver's seat or the
front passenger's seat.
Each time you push the switch, theairflow changes as follows:
The air v entilation seats default to
the OFF position whenever the
ignition switch is turned to the ON
position. To prevent damage to the air ven-
tilation seat system and seats:
Use the air ventilation seats
ONLY when the air conditioning
is on. Using the air ventilation
seats for prolonged periods of
time with the air conditioning off
could cause the air ventilation
seats to malfunction.
Never use a solvent such as paint thinner, benzene, alcohol
or gasoline to clean the seats.
Avoid spilling liquids on the sur- face of the front seats and seat-
backs; this may cause the air
vent holes to become blocked
and not work properly.
Do not place materials such as plastic bags or newspapers
under the seats. They may block
the air intake causing the air
vents to not work properly.
Do not change the seat covers. It may damage the air ventilation
seats.
(Continued)(Continued)
If the air vents do not operate,
restart the vehicle. If there is no
change, have your vehicle
inspected by an authorized
HYUNDAI dealer.NOTICE

The Pre-Tensioner Seat Belt System
consists mainly of the following com-
ponents. Their locations are shown in
the illustration above:
1. SRS air bag warning light
2. Retractor pre-tensioner
3. SRS control module
4. Anchor Pre-tensionerThe sensor that activates the SRS
air bag is connected with the
pre–tensioner seat belts. The SRS
air bag warning light on the instru-
ment panel will illuminate for
approximately 6 seconds after the
ignition switch is in the ON posi-
tion, and then it should turn off.
If the pre-tensioner is not working
properly, the warning light will illu-
minate 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.
Both the driver's and front pas-
senger's pre-tensioner seat
belts may be activated in certain
frontal or side collisions or
rollovers.
The pre-tensioners will not be activated if the seat belts are not
worn at the time of the collision.
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 breathed for
prolonged periods. Wash all
exposed skin areas thoroughly
after an accident in which the
pre-tensioner seat belts were
activated.

Securing a child restraint witha lap belt or 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.
Automatic locking mode
Since all passenger seat belts move
freely under normal conditions and
only lock under extreme or emer-
gency 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 caus-
ing the seat belt to loosen and com-
promise 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 instruc-
tions.
Be sure the seat belt webbing is
not twisted.
When using the rear center seat
belt, you should also refer to the
"3-point Rear Center Seat Belt"
section in this chapter.
NOTICE
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.

Occupant Classification
System (OCS)
Your vehicle is equipped with an
Occupant Classification System
(OCS) in the front passenger's seat.
Main components of theOccupant Classification System
A detection device located within
the front passenger seat cushion.
Electronic system to determine whether the passenger air bag
systems should be activated or
deactivated.
An indicator light located on the instrument panel which illuminates
the words "PASSENGER AIR BAG
OFF" indicating the front passen-
ger air bag system is deactivated.
The instrument panel air bag indi- cator light is interconnected with
the OCS.
The OCS is designed to help detect
the presence of a properly-seated
front passenger and determine if the
passenger's front air bag should be
enabled (may inflate) or not.
The purpose is to help reduce the
risk of injury or death from an inflat-
ing air bag to certain front passenger
seat occupants, such as children, by
requiring the air bag to be automati-
cally turned OFF. For example, if a child restraint of the
type specified in the regulations is on
the seat, the occupant classification
sensor can detect it and cause the
air bag to turn OFF.
Front passenger seat adult occu-
pants who are properly seated and
wearing the seat belt properly,
should not cause the passenger air
bag to be automatically turned OFF.
For small adults it may be turned
OFF, however, if the occupant does
not sit in the seat properly (for exam-
ple, by not sitting upright, by sitting
on the edge of the seat, or by other-
wise being out of position), this could
cause the sensor to turn the air bag
OFF.
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 the front
passenger air bag based on these
conditions.
