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 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.How Does the Air Bag System
Operate?
ODN8039033
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 (front)
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 sensors (acceleration)
10. Side impact sensors (pressure)
11. Driver’s knee air bag module
12. Occupant classification system
13. Side air bag modules (rear)
The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while the
Engine Start/Stop button is in the ON or
START 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 electrical 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
protection.
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 six seconds when the
Engine Start/Stop button is in the ON position.
• The light stays on after illuminating
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 conditions 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 provide adequate restraint. When
needed, 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) when the Engine Start/
Stop button is in the ON position or
approximately within 3 minutes after
ignition off.
• Air bags inflate in the event of certain
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 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 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 protection
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 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 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, especially if the
occupant is positioned excessively
close to the air bag.
You can take steps to help 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 space to
inflate. It is recommended that drivers sit
as far as possible between the center of
the steering wheel and the chest while
still maintaining control of the vehicle.
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 allowing 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 or the front passenger forward
motion, reducing the risk of head and
chest injury.
„„Driver’s front air bag (3)

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