Safety system of your vehicle
This vehicle is equipped with an
Advanced Supplemental Air Bag
System for the driver's seat and front
passenger's seats.
The front air bags are designed to
supplement the three-point seat
belts. For these air bags to provide
protection, the seat belts must be
worn at all times when driving.
You can be severely injured or killed
in an accident if you are not wearing
a seat belt. Air bags are designed to
supplement seat belts, but do not
replace them. Also, air bags are not
designed to deploy in every collision.
In some accidents, the seat belts are
the only restraint protecting you. AIR BAG SAFETY PRECAUTIONS
ALWAYS use seat belts and child restraints - every trip, every time,
everyone! Even with air bags, you can be seriously injured or killed in
a collision if you are improperly belted or not wearing your seat belt
when the air bag inflates.
NEVER place a child in any child restraint or booster seat in the front
passenger seat. An inflating air bag could forcefully strike the infant
or child causing serious or fatal injuries.
ABC - Always Buckle Children under age 13 in the back seat. It is the
safest place for children of any age to ride. If a child age 13 or older
must be seated in the front seat, he or she must be properly belted
and the seat should be moved as far back as possible.
All occupants should sit upright with the seatback in an upright posi-
tion, centered on the seat cushion with their seat belt on, legs com-
fortably extended and their feet on the floor until the vehicle is parked
and the engine is turned off. If an occupant is out of position during
an accident, the rapidly deploying air bag may forcefully contact the
occupant causing serious or fatal injuries.
You and your passengers should never sit or lean unnecessarily
close to the air bags or lean against the door or center console.
Move your seat as far back as possible from front air bags, while still
maintaining control of the vehicle. The U.S. National Highway Traffic
Safety Administration (NHTSA) recommends that drivers allow at
least 10 inches (25 cm) between the center of the steering wheel and
the chest.

Where Are the Air Bags?
Driver's and passenger's frontair bags
Your vehicle is equipped with a
Advanced Supplemental Restraint
System (SRS) and lap/shoulder belts
at both the driver and passenger
seating positions.
The SRS consists of air bags which
are located in the center of the steer-
ing wheel, in the driver's side lower
crash pad below the steering wheel
column and the passenger's side
front panel pad above the glove box.
The air bags are labeled with the let-
ters "AIR BAG" embossed on the
pad covers. The purpose of the SRS is to provide
the vehicle's driver and front passen-
gers with additional protection than
that offered by the seat belt system
alone. The SRS uses sensors to
gather information about the driver's
and front passenger's seat belt
usage and impact severity.
The seat belt buckle sensors deter-
mine if the driver and front passen-
ger's seat belts are fastened. These
sensors provide the ability to control
the SRS deployment based on
whether or not the seat belts are fas-
tened, and how severe the impact is.

The advanced SRS offers the ability
to control the air bag inflation within
two levels. A first stage level is pro-
vided for moderate-severity impacts.
A second stage level is provided for
more severe impacts.
According to the impact severity, and
seat belt usage, the SRS Control
Module (SRSCM) controls the air
bag inflation. Failure to properly wear
seat belts can increase the risk or
severity of injury in an accident.
Safety system of your vehicleTo reduce the risk of serious
injury or death from an inflating
front air bags, take the following
precautions:
Seat belts must be worn at all
times to help keep occupants
positioned properly.
Move your seat as far back as
possible from front air bags,
while still maintaining control
of the vehicle.
Never lean against the door or
center console.
Do not allow the front passen-
ger to place their feet or legs
on the dashboard.
No objects (such as crash pad
cover, cellular phone holder,
cup holder, perfume or stick-
ers) should be placed over or
near the air bag modules on
the steering wheel, instrument
panel, windshield glass, and
the front passenger's panel
above the glove box.
Such objects could cause
harm if the vehicle is in a
crash severe enough to cause
the air bags to deploy.
Do not attach any objects on
front windshield and inside
mirror.
WARNING

Safety system of your vehicle
Side air bags
Your vehicle is equipped with a side
air bag in each front seat.The purpose of the air bag is to pro-
vide the vehicle's driver and the front
passenger with additional protection
than that offered by the seat belt
alone.
The side air bags are designed to
deploy during certain side impact
collisions, depending on the crash
severity.
The side and curtain air bags on
both sides of the vehicle may deploy
if a rollover or possible rollover is
detected.
The side air bags are not designed to
deploy in all side impact or rollover
situations.

Do not allow passengers to
lean their heads or bodies
onto doors, put their arms on
the doors, stretch their arms
out of the window, or place
objects between the doors
and seats.
Hold the steering wheel at the
9 o'clock and 3 o'clock posi-
tions, to minimize the risk of
injuries to your hands and
arms.
Do not use any accessory
seat covers. This could reduce
or prevent the effectiveness
of the system.
Do not place any objects over
the air bag or between the air
bag and yourself. Also, do not
attach any objects around the
area the air bag inflates such
as the door, side door glass,
front and rear pillar.
Do not place any objects
between the door and the
seat. They may become dan-
gerous projectiles if the side
air bag inflates.
To reduce the risk of serious
injury or death from an inflating
side air bag, take the follo
wing
precautions:
Seat belts must be worn at all
times to help keep occupants
positioned properly.

Safety system of your vehicle
Curtain air bags
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors.They are designed to help protect
the heads of the front seat occupants
and the rear outboard seat occu-
pants in certain side impact colli-
sions.
The curtain air bags are designed to
deploy during certain side impact
collisions, depending on the crash
severity.
The side and curtain air bags on
both sides of the vehicle may deploy
if a rollover or possible rollover is
detected.
The curtain air bags are not designed
to deploy in all side impact or rollover
situations.
Do not install any accessories
on the side or near the side air
bags.
Do not put any objects
between the side airbag label
and seat cushion. It could
cause harm if the vehicle is in
a crash severe enough to
cause the air bags to deploy.
Do not cause impact to the
doors when the ignition
switch is in the ON position or
this may cause the side air
bags to inflate.
If the seat or seat cover is
damaged, have the vehicle
checked and repaired by an
authorized HYUNDAI dealer.

the ON position to determine if a
crash impact is severe enough to
require air bag deployment or pre-
tensioner seat belt deployment.
SRS warning light
The SRS (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration.
The system checks the air bag elec-
trical 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 pro-
tection.
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 condi-
tions occur, your SRS is mal-
functioning:
The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
The light stays on after illumi-
nating 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 con-
ditions 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 pro-
vide adequate restraint. When need-
ed, the side air bags help provide
protection in the event of a side
impact or rollover.
Air bags are activated (able toinflate if necessary) only when the
ignition switch is in the ON posi-
tion.
Air bags inflate in the event of cer- tain 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 acci-
dent. It is much more likely that you
will simply see the deflated air
bags hanging out of their storage
compartments after the collision.
In addition to inflating in certain side collisions, vehicles equipped
with a rollover sensor, side and
curtain air bags will inflate if the
sensing system detects a rollover.
When a rollover is detected, side
and curtain air bags will remain
inflated longer to help provide pro-
tection from ejection, especially
when used in conjunction with the
seat belts. To help provide protection, the air
bags must inflate rapidly. The
speed of air bag inflation is a con-
sequence of extremely short time
in which to inflate the air bag
between the occupant and the
vehicle structures before the occu-
pant impacts those structures. This
speed of inflation reduces the risk
of serious or life-threatening
injuries and is thus a necessary
part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises
and broken bones because the
inflation speed also causes the air
bags to expand with a great deal of
force.
There are even circumstances under which contact with the air
bag can cause fatal injuries, espe-
cially if the occupant is positioned
excessively close to the air bag.

Safety system of your vehicle
You can take steps to help reduce
the risk of being injured by an inflat-
ing air bag. The greatest risk is sitting
too close to the air bag. An air bag
needs about 10 inches (25 cm) of
space to inflate. NHTSA recom-
mends that drivers allow at least 10
inches (25 cm) between the center of
the steering wheel and the chest.
When the SRSCM detects a suffi-
ciently severe impact to the front of
the vehicle, it will automatically
deploy the front air bags.
To reduce the risk of serious
injury or death from an inflating
air bag, take the following pre-
cautions:
NEVER place a child restraint
in the front passenger seat.
Always properly restrain chil-
dren under age 13 in the rear
seats of the vehicle.
Adjust the front passenger's
and driver's seats as far to the
rear as possible while allow-
ing you to maintain full con-
trol of the vehicle.
Hold the steering wheel with
hands at the 9 o'clock and 3
o'clock positions.
Never place anything or any-
one between the air bag and
the seat occupant.
Do not allow the front passen-
ger to place their feet or legs
on the dashboard.

Upon deployment, tear seams mold-
ed directly into the pad covers will
separate under pressure from the
expansion of the air bags. Further
opening of the covers allows full
inflation of the air bags.
A fully inflated air bag, in combina-
tion with a properly worn seat belt,
slows the driver or the front passen-
ger forward motion, reducing the risk
of head and chest injury.After complete inflation, the air bag
immediately starts deflating,
enabling the driver to maintain for-
ward visibility and the ability to steer
or operate other controls.
