How Does the Air Bag System
Operate?
The SRS consists of the following
components:
1. Driver's front air bag module
2. Passenger's front air bag module
3. Side air bag modules
4. Curtain air bag modules
5. Retractor pre-tensioner assemblies
6. Air bag warning light
7. SRS control module (SRSCM)/
Rollover sensor
8. Front impact sensors
9. Side impact sensors10. Side pressure sensors
11. The front passenger's seat belt
buckle sensors
12. Emergency Fastening Device
(EFD)
13. Occupant classification system
The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while
the ignition switch is in the ON posi-
tion to determine if a crash impact is
severe enough to require air bag
deployment or pre-tensioner seat belt
deployment.
Information
The seat belt buckle sensor deter-
mines whether the front passenger's
seat belt is fastened. According to
whether the seat belt is fastened or not
and how severe the impact is, this sen-
sor provides the function to control
the SRS 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.

During a frontal collision, sensors will
detect the vehicle's deceleration. If
the rate of deceleration (measured in
g-force) 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 to
inflate if necessary) only when the
ignition switch is in the ON position.
Air bags inflate in the event of cer-
tain frontal or side collisions to help
protect the occupants 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 colli-
sion and its direction, etc. These
two factors determine whether the
sensors produce an electronic
deployment/inflation signal. Air bag deployment depends on a
number of factors including vehicle
speed, angles of impact and the
density and stiffness of the vehicles
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 you
will simply see the deflated air bags
hanging out of their storage com-
partments 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. If your SRS malfunctions, the air
bag may not inflate properly dur-
ing 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 remains illuminated
after approximately six sec-
onds.
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.

What to Expect After an Air
Bag Inflates
After a frontal or side air bag inflates,
it will deflate very quickly. Air bag
inflation will not prevent the driver
from seeing out of the windshield or
being able to steer. Curtain air bags
may remain partially inflated for
some time after they deploy.
After an air bag inflates, take
the following precautions:
Open your windows and doors
as soon as possible after
impact to reduce prolonged
exposure to the smoke and
powder released by the inflat-
ing air bag.
Do not touch the air bag stor-
age area's internal compo-
nents immediately after an air
bag has inflated. The parts
that come into contact with an
inflating air bag may be very
hot.
WARNING
Always wash exposed skin
areas thoroughly with cold
water and mild soap.
Always have an authorized
HYUNDAI dealer replace the air
bag immediately after deploy-
ment. Air bags are designed to
be used only once.
To prevent objects from becom-
ing dangerous projectiles when
the passenger's air bag inflates:
Do not install or place any
objects (drink holder, CD
holder, stickers, etc.) on the
front passenger's panel above
the glove box where the pas-
senger’s air bag is located.
Do not install a container of
liquid air freshener near the
instrument cluster or on the
instrument panel surface.

Noise and smoke from inflating
air bag
When the air bags inflate, they make
a loud noise and may produce
smoke and powder in the air inside of
the vehicle. This is normal and is a
result of the ignition of the air bag
inflator. After the air bag inflates, you
may feel substantial discomfort in
breathing because of the contact of
your chest with both the seat belt and
the air bag, as well as from breathing
the smoke and powder. The powder
may aggravate asthma for some
people. If you experience breathing
problems after an air bag deploy-
ment, seek medical attention imme-
diately.
Though the smoke and powder are
nontoxic, they may cause irritation to
the skin, eyes, nose, throat, etc. If
this is the case, wash and rinse with
cold water immediately and seek
medical attention if the symptoms
persist.
Occupant Classification
System (OCS)
Your vehicle is equipped with an
Occupant Classification System
(OCS) in the front passenger's seat.
Main components of the
Occupant 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.

Safety system of your vehicle
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.Always be sure that you and all vehi-
cle occupants are seated properly
and wearing the seat belt properly for
the most effective protection by the
air bag and the seat belt.
The OCS may not function properly if
the passenger takes actions which
can affect the classification system.
These include:
Failing to sit in an upright position.
Leaning against the door or center
console.
Sitting towards the sides of the
front of the seat.
Putting their legs on the dashboard
or resting them on other locations
which reduce the passenger
weight on the front seat.
Wearing the seat belt improperly.
Reclining the seatback.

Riding in an improper position or placing weight on the front passenger's seat when it is unoccupied by a
passenger adversely affects the OCS. To reduce the risk of serious injury or death:

Air bag inflation conditions
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on
the severity, speed, or angles of
impact of the front collision.
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, speed, or
angles of impact resulting 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 to
inflate only in side impact collisions
or rollover situations, but they may
inflate in other collisions if the side
impact sensors detect a sufficient
impact.
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.

Air bag non-inflation conditions
In certain low-speed collisions the air
bags may not deploy. The air bags
are designed not to deploy in such
cases because they may not provide
benefits beyond the protection of the
seat belts.Front air bags are not designed to
inflate in rear collisions, because
occupants are moved backward by
the force of the impact. In this case,
inflated air bags would not provide
any additional benefit.Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide addi-
tional occupant protection.
However, side and curtain air bags
may inflate depending on the severi-
ty, vehicle speed and angles of
impact.
OTLE038066
OTLE038065OTLE038067

Safety system of your vehicle
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.
