Side air bags
„Side air bag
OTM030029
OTM030030
Your vehicle is equipped with a side air
bag in each front seat. The purpose of
the air bag is to provide 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, angle,
speed and point of impact.
The side air bags on both sides of the
vehicle are designed to deploy when a
rollover is detected by a rollover sensor.
(if equipped with rollover sensor)
The side air bags are not designed to
deploy in all side impact or rollover
situations.
WARNING
To reduce the risk of serious injury or
death from an inflating side air bag and
front center air bag, take the following
precautions:

[ Seat belts must be worn at all times
to help keep occupants positioned
properly.

[ 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 positions, 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 hang other objects except
clothes. In an accident it may cause
vehicle damage or personal injury
especially when air bag is inflated.

[ 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 dangerous projectiles if the
side air bag inflates.

[ Do not install any accessories on the
side or near the side air bags.

[ Do not cause impact to the doors
when the Engine Start/Stop button
is in the ON or START position as this
may cause the side air bags to inflate.

[ If the seat or seat cover is damaged,
have the system be serviced by an
authorized HYUNDAI dealer.

Curtain air bags
OTM030031
OTM030032
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 occupants in
certain side impact collisions.
The curtain air bags are designed to
deploy during certain side impact
collisions, depending on the crash
severity, angle, speed and impact.For vehicles equipped with a rollover
sensor the side and/or curtain air bags
and pre-tensioners 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.
WARNING
To reduce the risk of serious injury or
death from an inflating curtain air bag,
take the following precautions:

[
All seat occupants must wear
seat belts at all times to help keep
occupants positioned properly.

[ Properly secure Child Restraint
System 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 attempt to open or repair
the side curtain air bags yourself. If
necessary, have the air bag inspected
by an authorized HYUNDAI dealer.

Seats & Safety System3-50
How does the air bags system
operate?
OTMH030008N
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
(6) Air bag warning light
(7) SRS control module (SRSCM)/ Rollover sensor
(8) Front impact sensors
(9) Side impact sensors
(10) Side pressure sensors
(11) Seat belt buckle sensor
(12) Emergency fastening device system
(13) Occupant classification system
The SRSCM continually monitors all SRS
components while the ignition switch
is ON 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 (Supplemental Restraint System)
air bag w
arning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential problem with your
air bag system, which could include
your side and/or curtain air bags used
for rollover protection (if equipped with
rollover sensor).
WARNING
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 conditions occur,
your SRS is malfunctioning:

[ The light does not turn on for
approximately three to six seconds
when the Engine Start/Stop button is
in the ON position.

[ The light stays on after illuminating
for approximately three to 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 conditions occur.

03
3-51
During a moderate to severe frontal
collision, sensors will detect the
vehicle’s rapid deceleration. If the rate of
deceleration is high enough, the control
unit will inflate the front air bags, at the
time and with the force needed.
The front air bags help protect the driver
and front passenger by responding to
frontal impacts in which seat belts alone
cannot provide adequate restraint. When
needed, the side air bags help provide
protection in the event of a side impact
or rollover by supporting the side upper
body area.

[Air bags are activated (able to
inflate if necessary) only when the
Engine Start/Stop button is in the
ON or START position, and it can be
activated within about 3 minutes after
the engine is turned off.

[ Air bags inflate in the event of certain
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 collision and its direction.
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 accident. 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 serious side
collisions, vehicles equipped with a
rollover sensor, side and/or curtain air
bags will inflate if the sensing system
detects a rollover.
When a rollover is detected, curtain
air bags will remain inflated longer to
help provide protection from ejection,
especially when used in conjunction
with the seat belts. (if equipped with a
rollover sensor)

[ To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which
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
lifethreatening 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, especially if the
occupant is positioned excessively
close to the air bag.
You can take steps to reduce the risk
of being injured by an inflating air bag.
The greatest risk is sitting too close to
the air bag. An air bag needs about 10
in. (25 cm) of space to inflate. NHTSA
recommends that drivers allow at least
10 in. (25 cm) between the center of the
steering wheel and the chest.

Seats & Safety System3-52
WARNING
To reduce the risk of serious injury or
death from an inflating air bag, take the
following precautions:

[ NEVER place a child restraint in the
front passenger seat.
Always properly restrain children
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 maintaining you to
maintain full control of the vehicle.

[ Hold the steering wheel with
hands at the 9 o'clock and 3 o'clock
positions.

[ Never place anything or anyone
between the air bag and the seat
occupant.

[ Do not allow the front passenger
to place their feet or legs on the
dashboard.
„Driver’s front air bag (1)
ODN8039077L
When the SRSCM detects a sufficiently
severe impact to the front of the vehicle,
it will automatically deploy the front air
bags.
„Driver’s front air bag (2)
ODN8039078L
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
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 front passenger’s forward
motion, reducing the risk of head and
chest injury.

03

„Driver’s front air bag (3)
ODN8039079L
„Passenger’s front air bag
ODN8039080L
After complete inflation, the air bag
immediately starts deflating, enabling
the driver to maintain forward visibility
and the ability to steer or operate other
controls.
WARNING
To prevent objects from becoming
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
passenger’s air bag is located.

[ Do not install a container of liquid
air freshener near the instrument
cluster or on the instrument panel
surface.
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.
WARNING
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
inflating air bag.

[ Do not touch the air bag storage
area’s internal components
immediately after an air bag has
inflated. The parts that come into
contact with an inflating air bag may
be very hot.

[ Always wash exposed skin areas
thoroughly with cold water and mild
soap.

[ Have an authorized HYUNDAI dealer
replace the air bag immediately after
deployment. Air bags are designed to
be used only once.

Seats & Safety System3-54
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 deployment,
seek medical attention immediately.
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)
OTMA030003
Your vehicle is equipped with an
Occupant Classification System (OCS) in
the front passenger’s seat.

03
3-55
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
overhead console which illuminates
the words “PASSENGER AIR BAG OFF”
indicating the front passenger air bag
system is deactivated.

[ The overhead console air bag
indicator 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 inflating air
bag to certain front passenger seat
occupants, such as children, by requiring
the air bag to be automatically 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 occupants
who are properly seated and wearing the
seat belt properly, should not cause the
passenger air bag to be automatically
turned OFF. For smaller adults it may turn
OFF, however, if the occupant does not
sit in the seat properly (for example, by
not sitting upright, by sitting on the edge
of the seat, or by otherwise 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 overhead console
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 vehicle
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.

[ Wearing thick clothes like ski wear or
hip protection wear.

[ Putting an additional thick cushion on
the seat.

[ Putting electrical devices (for
example, notebook, satellite radio) on
the seat with inverter charging.
