How does the air bag system operate
Air bags are activated (able to inflate ifnecessary) only when the engine
start/stop button is turned to the ON or
START position.
Air bags inflate instantly in the event of a serious frontal collision or side colli-sion in order to help protect the occu-
pants from serious physical injury.
There is no single speed at which the air bags will inflate.
Generally, air bags are designed to
inflate based upon the severity of a col-
lision and its direction. These two fac-
tors determine whether the sensors
produce an electronic deployment/inflation signal.
Air bag deployment depends on a number of factors including vehiclespeed, angles of impact and the densi-
ty and stiffness of the vehicles or
objects which your vehicle hits in the
collision. The determining factors are
not limited to those mentioned above.
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 sim-ply see the deflated air bags hanging
out of their storage compartments afterthe collision.
In order to help provide protection in a severe collision, the air bags must
inflate rapidly. The speed of air baginflation is a consequence of the
extremely short time in which a collisionoccurs and the need to inflate the air
bag between the occupant and the
vehicle structures before the occupant
impacts those structures. This speed of
inflation reduces the risk of serious or
life-threatening injuries in a severe col-
lision and is thus a necessary part of airbag design.
However, air bag inflation can also
cause injuries which can include facial
abrasions, bruises and broken bonesbecause the inflation speed also caus-
es the air bags to expand with a great
deal of force.
There are even circumstances under which contact with the steer-
ing wheel air bag can cause fatal
injuries, especially if the occupant
is positioned excessively close tothe steering wheel.
WARNING
To avoid severe personal injury or death caused by deploying air
bags in a collision, the driver
should sit as far back from the
steering wheel air bag as possi-
ble (at least 250 mm (10 inches)
away). The front passengers
should always move their seats
as far back as possible and sit
back in their seat.
Air bags inflate instantly in the event of collision, and passen-
gers may be injured by the air bag
expansion force if they are not in
a proper position.
Air bag inflation may cause injuries including facial or bodily
abrasions, injuries from broken
glasses or burns.

WARNING
Extreme Hazard! Do not use a rearward facing child restraint on
a seat protected by an air bag in
front of it!
Never put a child restraint in the front passenger’s seat. If the front
passenger air bag inflates, it cancause serious or fatal injuries.
When children are seated in the rear outboard seats of a vehicle
equipped with side and/or curtain
air bags, be sure to install the
child restraint system as far away
from the door side as possible,
and securely lock the childrestraint system in position.
Inflation of side and/or curtain air
bags could cause serious injury
or death to an infant or child.
Noise and smoke
When the air bags inflate, they make a
loud noise and they leave smoke and
powder in the air inside of the vehicle.
This is normal and is a result of the igni-
tion of the air bag inflator. After the air
bag inflates, you may feel substantial dis-
comfort in breathing due to the contact of
your chest with both the seat belt and the
air bag, as well as from breathing the
smoke and powder. Open your doors
and/or windows as soon as possible
after impact in order to reduce dis-
comfort and prevent prolonged expo-
sure to the smoke and powder.
Though the smoke and powder are non-
toxic, they may cause irritation to the skin
(eyes, nose and throat, etc). If this is the
case, wash and rinse with cold waterimmediately and consult a doctor if the
symptom persists.
Do not install a child restraint on the
front passenger’s seat.
Never place a rear-facing child restraint
in the front passenger’s seat. If the air
bag deploys, it would impact the rear-fac-
ing child restraint, causing serious or
fatal injury.
In addition, do not place front-facing child
restraints in the front passenger’s seat
either. If the front passenger air bag
inflates, it could cause serious or fatal
injuries to the child.

WARNING
When the air bags deploy, the air
bag related parts in the steeringwheel and/or instrument panel
and/or in both sides of the roof rails
above the front and rear doors are
very hot. To prevent injury, do not
touch the air bag storage area’s
internal components immediately
after an air bag has inflated.

Air bag warning light
The purpose of the air bag warning light
in your instrument panel is to alert you of
a potential problem with your air bag -
Supplemental Restraint System (SRS).
When the ignition switch is turned ON,
the warning light should illuminate for
approximately 6 seconds, then go off.
Have the system checked if:
The light does not turn on briefly whenyou turn the engine start/stop button to the ON position.
The light stays on after illuminating for approximately 6 seconds.
The light comes on while the vehicle is in motion.
The light blinks when the engine start/stop button is in ON position. SRS components and functions
The SRS consists of the following com- ponents:
1. Driver's front air bag module
2. Passenger's front air bag module
3. Side impact air bag modules
4. Curtain air bag modules
5. Retractor pre-tensioner assemblies
6. Air bag warning light
7. SRS control module (SRSCM)
8. Front impact sensors
9. Side impact sensors
10. Driver’s knee air bag module
11. Driver’s and front passenger’s seat
belt buckle sensors. The SRSCM continually monitors all SRS components while the engine
start/stop button is ON to determine if a
crash impact is severe enough to require
air bag deployment or pre-tensioner seat
belt deployment.
The SRS air bag warning light " " on
the instrument panel will illuminate forabout 6 seconds after the engine
start/stop button is turned to the ON posi-
tion, after which the SRS air bag warning
light " " should go out.

The front air bag modules are located in
the center of the steering wheel, in the
front passenger's panel above the glove
box and/or in the driver’s side knee bol-
ster. When the SRSCM detects a suffi-
ciently severe impact to the front of the
vehicle, it will automatically deploy the
front air bags. Upon deployment, tear seams molded
directly into the pad covers will separate
under pressure from the expansion of the
air bags. Further opening of the covers
then allows full inflation of the air bags.
A fully inflated air bag, in combination
with a properly worn seat belt, slows the
driver's or the passenger's forward
motion, reducing the risk of head and
chest injury. After complete inflation, the air bag
immediately starts deflating, enabling the
driver to maintain forward visibility and
the ability to steer or operate other con-
trols.

WARNING
Do not install or place any acces- sories (drink holder, cassette
holder, sticker, etc.) on the front
passenger's panel above the
glove box in a vehicle with a pas-
senger's air bag. Such objects
may become dangerous projec-
tiles and cause injury if the pas-
senger's air bag inflates.
When installing a container of liq- uid air freshener inside the vehi-
cle, do not place it near the
instrument cluster nor on the
instrument panel surface.
It may become a dangerous pro-
jectile and cause injury if the pas-
senger's air bag inflates.

Passenger’s front air bag
WARNING
If an air bag deploys, there may be a loud noise followed by a fine
dust released in the vehicle.These conditions are normal and
are not hazardous - the air bags
are packed in this fine powder.
The dust generated during air
bag deployment may cause skin
or eye irritation as well as aggra-
vate asthma for some persons.
Always wash all exposed skin
areas thoroughly with lukewarmwater and a mild soap after an
accident in which the air bags
were deployed.
The SRS can function only when the engine start/stop button is in
the ON position. If the SRS " "
warning light does not illuminate,
or continuously remains on after
illuminating for about 6 seconds
when the engine start/stop but-ton 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 imme-
diately inspected by an author-
ized HYUNDAI dealer.
(Continued)(Continued)
Before you replace a fuse or dis-connect a battery terminal, turn
the engine start/stop button to
the OFF position. Never remove
or replace the air bag relatedfuse(s) when the engine
start/stop button is in the ON
position. Failure to heed this
warning will cause the SRS “ ”
warning light to illuminate.

Driver's and passenger's front air
bag
Your vehicle is equipped with a
Supplemental Restraint (Air Bag) Systemand the lap/shoulder belts at both the
driver and passenger seating positions. The indications of the system's presence
are the letters "SRS AIR BAG"
embossed on the air bag pad cover in the
steering wheel and/or on the cover of the
driver's side knee bolster located below
the steering wheel and the passenger's
side front panel pad above the glove box.
The SRS consists of air bags installed
under the pad covers in the center of the
steering wheel , in the knee bolster below
the steering wheel column and the pas-
senger's side front panel above the glove
box.
The purpose of the SRS is to provide the
vehicle's driver and/or the front passen-ger with additional protection than that
offered by the seat belt system alone incase of a frontal impact of sufficient
severity. The SRS uses sensors to gath-
er information about the driver's seat
position, the driver's and front passen-
ger's seat belt usage and impact severi-
ty.

Safety features of your vehicle
The seat belt buckle sensors (if
equipped) determine if the driver and
front passenger's seat belts are fas-
tened. 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.(Continued)
ABC – Always Buckle Children inthe back seat. It is the safest place
for children of any age to ride.
Front and side impact air bags can injure occupants improperlypositioned.
Move your seat as far back as practical from the front air bags,
while still maintaining control of
the vehicle.
You and your passengers should never sit or lean unnecessarily
close to the air bags. Improperly
positioned drivers and passen-
gers can be severely injured by
inflating air bags.
Never lean against the door or center console – always sit in an upright position.
No objects should be placed over or near the air bag modules on
the steering wheel, instrument
panel, driver’s side knee bolster,
and the front passenger's panel
above the glove box, because any
such object could cause harm if
the vehicle is in a crash severe
enough to cause the air bags to
deploy.
(Continued)(Continued)
Do not tamper with or disconnectSRS wiring or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental deployment of the air bags
or by rendering the SRS inopera-
tive.
If the SRS air bag warning light “ ”remains illuminated while
the vehicle is being driven, have
an authorized HYUNDAI dealer
inspect the air bag system as
soon as possible.
Air bags can only be used once – have an authorized HYUNDAI
dealer replace the air bag imme-
diately after deployment.
The SRS is designed to deploy the front air bags only when an
impact is sufficiently severe andwhen the impact angle is less
than 30° from the forward longitu-
dinal axis of the vehicle.
Additionally, the air bags will only
deploy once. Seat belts must be
worn at all times.
(Continued)
WARNING
Always use seat belts and child
restraints – every trip, every time,
everyone! Air bags inflate with con-
siderable force and in the blink of
an eye. Seat belts help keep occu-
pants in proper position to obtain
maximum benefit from the air bag.
Even with air bags, improperly belt-ed and unbelted occupants can be
severely injured when the air bag
inflates. Always follow the precau-
tions about seat belts, air bags and
occupant safety contained in this
manual.
To reduce the chance of serious or fatal injuries and receive the maxi-
mum safety benefit from yourrestraint system:
Never place a child in any child or booster seat in the front seat.

Side impact air bag
(Continued)
Front air bags are not intended to
deploy in side-impact, rear-
impact or rollover crashes. In
addition, front air bags will not
deploy in frontal crashes below
the deployment threshold.
A child restraint system must never be placed in the front seat.
The infant or child could be
severely injured or killed by an air
bag deployment in case of anaccident.
Children age 12 and under must always be properly restrained in
the rear seat. Never allow chil-
dren to ride in the front passen-
ger seat. If a child over 12 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.
(Continued)(Continued)
For maximum safety protection inall types of crashes, all occu-
pants including the driver should
always wear their seat belts
whether or not an air bag is also
provided at their seating position
to minimize the risk of severe
injury or death in the event of a
crash. Do not sit or lean unneces-
sarily close to the air bag while
the vehicle is in motion.
Sitting improperly or out of posi- tion can result in serious or fatal
injury in a crash. All occupantsshould sit upright with the seat
back in an upright position, cen-tered on the seat cushion with
their seat belt on, legs comfort-
ably extended and their feet on
the floor until the vehicle is
parked and the engine start/stop
button is in the OFF position.
The SRS air bag system must deploy very rapidly to provide
protection in a crash. If an occu-pant is out of position because of
not wearing a seat belt, the air
bag may forcefully contact theoccupant causing serious or fatalinjuries.

Use of seat covers could reduceor prevent the effectiveness of the system.
Do not install any accessories on the side or near the side impact
air bag.
Do not place any objects over the air bag or between the air bag
and yourself.
Do not place any objects (an umbrella, bag, etc.) between the
door and the seat. Such objects
may become dangerous projec-
tiles and cause injury if the sup-
plemental side impact air baginflates.
To prevent unexpected deploy- ment of the side impact air bag
that may result in personal injury,
avoid impact to the side impact
sensor when the ignition switchis on.
If the seat or seat cover is dam- aged, have the vehicle checked
and repaired by an authorized
HYUNDAI dealer because your
vehicle is equipped with side
impact air bags.Your vehicle is equipped with a side impact air bag in each front and outboard
rear seat. The purpose of the air bag is to
provide the vehicle's driver and/or thefront and outboard rear passengers with
additional protection than that offered by
the seat belt alone.
The side impact air bags are designedto deploy during certain side-impact
collisions, depending on the crash
severity, angle, speed and point ofimpact.
The side impact air bags are not designed to deploy in all side impact.
WARNING
The side impact air bag is sup- plemental to the driver’s and the
passengers seat belt systems
and is not a substitute for them.
Therefore your seat belts must be
worn at all times while the vehicle
is in motion. The air bags deploy
only in certain side impact condi-
tions severe enough to cause
significant injury to the vehicleoccupants.
For best protection from the side impact air bag system and to
avoid being injured by the
deploying side impact air bag,
both front and all rear (ifequipped) seat occupants shouldsit in an upright position with the
seat belt properly fastened. Thedriver's hands should be placedon the steering wheel at the 9:00
and 3:00 positions. The passen-
ger’ arms and hands should beplaced on their laps.
Do not use any accessory seat covers.

Curtain air bag
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 andthe rear outboard seat occupants in cer-
tain side impact collisions. The curtain air bags are designed to
deploy only during certain side impact
collisions, depending on the crash sever-
ity, angle, speed and impact. The curtain
air bags are not designed to deploy in all
side impact situations, collisions from the
front or rear of the vehicle or in most
rollover situations.
WARNING
In order for side and curtain air bags to provide the best protec-
tion, front seat occupants and
outboard rear occupants shouldsit in an upright position with the
seat belts properly fastened.
Importantly, children should sit in
a proper child restraint system inthe rear seat.

When children are seated in therear outboard seats, they must be
seated in the proper child
restraint system. Make sure to
position the child restraint sys-
tem as far away from the door
side as possible, and secure the
child restraint system in a lockedposition.
Do not allow the 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 passen-
gers when they are seated onseats equipped with side and/or
