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. Emergency Fastening DeviceSystem The 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, staysilluminated or illuminates when
the vehicle is being driven, have
an authorized HYUNDAI dealerinspect 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.
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 normaloperating 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 thepre-tensioner seat belts were
activated.

They are designed to help protect the heads of the front seat occupantsand the rear outboard seat occu-
pants in certain side impact colli-
sions.
The curtain air bags are designed to
deploy only 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 isdetected.
The curtain air bags are not
designed to deploy in all side impact
or rollover situations.How Does the Air Bag System Operate?
The SRS consists of the following components:
1. Driver's front air bag module/Driver's knee airbag module
2. Passenger's front air bag module
3. Side air bag modules/ Side impact sensors
4. Curtain air bag modules
5. Retractor pre-tensioner assem- blies
6. Air bag warning light
7. SRS control module (SRSCM)/ Rollover sensor
To reduce the risk of serious
injury or death from an inflating
curtain air bag, take the follow-ing precautions:
All seat occupants must wear seat belts at all times to helpkeep occupants positioned
properly.
(Continued)
(Continued)
Properly secure child
restraints as far away from the
door as possible.
Do not place any objects over
the air bag. Also, do not attach
any objects around the area
the air bag inflates such as the
door, side door glass, front
and rear pillar, roof side rail.
Do not hang other objects
except clothes, especially
hard or breakable objects. In
an accident, it may cause
vehicle damage or personal
injury.
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.
Do not open or repair the side
curtain air bags.

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. Thelight 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 properlyduring an accident increasing
the risk of serious injury ordeath.
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 inthe ON position.
The light stays on after illumi-
nating for approximately sixseconds.
The light comes on while the
vehicle is in motion.
The light blinks when the engine is running.
Have an authorized HYUNDAIdealer inspect the SRS as soon
as possible if any of these con-
ditions occur.

Safety system of your vehicle
During a frontal collision, sensors will
detect the vehicle's deceleration. If
the rate of deceleration is highenough, the control unit will inflate
the front air bags. The front air bags help protect the
driver and front passenger byresponding to frontal impacts inwhich 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
Engine Start/Stop button is in theON position.
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 thesensors produce an electronic
deployment/inflation signal. Air bag deployment depends on a
number of factors including vehiclespeed, angles of impact and the
density and stiffness of the vehi-
cles or objects which your vehicle
impacts during a 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 acci-
dent. It is much more likely that youwill 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, especiallywhen used in conjunction with the
seat belts. To help provide protection, the air
bags must inflate rapidly. Thespeed of air bag inflation is a con-
sequence of extremely short timein 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 theinflation 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
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 BAGOFF" 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 thepassenger'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 thetype specified in the regulations is onthe seat, the occupant classificationsensor 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
fascia panel. This system detects the
conditions 1-4 in the following table
and activates or deactivates the frontpassenger air bag based on these
conditions.

Do not sit on the passen-
ger seat wearing heavily
padded clothes such as
ski wear and hip protector.
Do not use car seat
accessories such as thick
blankets and cushions
which cover up the car
seat surface.
Do not place electronic
devices such as laptops,
DVD player, or conductive
materials such as water
bottles on the passengerseat.
Do not use electronic
devices such as laptops
and satellite radios which
use inverter chargers.
If large quantity of liquid has been spilled on the
passenger seat, the air
bag warning light mayilluminate or malfunction.
Therefore, make sure the
seat has been completely
dried before driving the
vehicle.
Do not place sharp objects on the front passenger seat. These may damage the occupant detection sys-
tem, if they puncture the seat cushion.
Do not place any items under the front passenger seat.
When changing or replacing the seat or seat cover, use original items only. The OCS has been devel-
oped based on using original HYUNDAI car seats only. Altering or changing the authentic parts may
result in system malfunction and increase risk of injury when in collision. Any of the above could inter-
fere with the proper operation of the OCS sensor thereby increasing the risk of an injury in an accident.

Why Didn't My Air Bag Go Off in a Collision?
Air bags are not designed to inflate in
every collision. There are certaintypes of accidents in which the air
bag would not be expected to pro-
vide additional protection. These
include rear impacts, second or third
collisions in multiple impact acci-
dents, as well as low speed impacts.
Damage to the vehicle indicates a
collision energy absorption, and isnot an indicator of whether or not an
air bag should have inflated.
Air bag collision sensors
NEVER place a rear-facing or
front-facing child restraint in
the front passenger's seat of
the vehicle.
An inflating frontal air bag
could forcefully strike a child
resulting in serious injury ordeath.
Always properly restrain chil-
dren in an appropriate childrestraint in the rear seat of the
vehicle.
WARNING
To reduce the risk of an air bag
deploying unexpectedly and
causing serious injury or death:
Do not hit or allow any objects to impact the locations where
air bags or sensors areinstalled.(Continued)
WARNING
(Continued)
Do not perform maintenance
on or around the air bag sen-
sors. If the location or angle of
the sensors is altered, the air
bags may deploy when they
should not or may not deploy
when they should.
Do not install bumper guards
or replace the bumper with a
non-genuine HYUNDAI parts.
This may adversely affect the
collision and air bag deploy-
ment performance.
Place the ignition switch in
the LOCK/OFF or ACC posi-
tion when the vehicle is being
towed to prevent inadvertent
air bag deployment.
Have all air bag repairs con-
ducted by an authorized
HYUNDAI dealer.

Air bag inflation conditions
Front air bags
Front air bags and the driver's knee air bag are designed to inflate in afrontal collision depending on the
severity of impact of the front colli-sion.
Side and curtain air bags
Side and curtain air bags are designed to inflate when an impact is
detected by side collision sensors
depending on the severity of impactresulting from a side impact collision.Although the driver's and front pas-senger's air bags are designed to
inflate only in frontal collisions, they
also may inflate in other types of col-lisions if the front impact sensors
detect a sufficient impact. Side and
curtain air bags are designed toinflate only in side impact collisions
or rollover situations, but they mayinflate in other collisions if the sideimpact sensors detect a sufficientimpact.
If the vehicle chassis is impacted by
bumps or objects on unimproved
roads, the air bags may deploy. Drive
carefully on unimproved roads or on
surfaces not designed for vehicle
traffic to prevent unintended air bag
deployment.

In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to "ride" under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
"underride" collisions.Front air bags may not inflate in
rollover accidents because air bag
deployment could not provide protec-
tion to the occupants.
However, side and curtain air bags
may inflate when the vehicle is rolled
over by a side impact collision.
