Where are the air bags?
Driver’s and passenger’s front
air bags
Your vehicle is equipped with a
Advanced Supplemental Restraint
System (SRS) and lap/shoulder belts
at both the driver and passenger
seating positions.
The SRS consists of air bags which
are located in the center of the steer-
ing wheel and the passenger's side
front panel pad above the glove box.
The air bags are labeled with the let-
ters “AIR BAG” embossed on the pad
covers.The purpose of the SRS is to provide
the vehicle's driver and front passen-
gers with additional protection than
that offered by the seat belt system
alone. The SRS uses sensors to
gather information about the driver's
seat position, the driver's and front
passenger's seat belt usage and
impact severity.
To reduce the risk of serious
injury or death from an inflating
front air bags, take the following
precautions:
Seat belts must be worn at all
times to help keep occupants
positioned properly.
Move your seat as far back as
possible from front air bags,
while still maintaining control
of the vehicle.
Never lean against the door or
center console.

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 only during certain side
impact collisions, depending on the
crash severity, angle, speed and
impact.
The curtain air bags do not only
deploy on the side of the impact but
also on the opposite side.
For vehicles equipped with a rollover
sensor the side and curtain air bags
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.How does the air bags 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 sensors To reduce the risk of serious
injury or death from an inflating
curtain air bags, take the follow-
ing 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 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.

The SRSCM continually monitors all
SRS components while the Engine
Start/Stop button 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.
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 indi-
cates that there is a potential problem
with your air bag system, which could
include your side and curtain air bags
used for rollover protection.
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 Engine Start/Stop
button is in the ON position.
The light stays on after illumi-
nating 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 con-
ditions occur.

During a moderate to severe frontal
collision, sensors will detect the vehi-
cle’s rapid deceleration. If the rate of
deceleration is high enough, the con-
trol 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 protec-
tion 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 position.
Air bags inflate in the event of a
severe frontal or side collision 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. These two
factors determine whether the sen-
sors produce an electronic deploy-
ment/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 serious
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. 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, espe-
cially if the occupant is positioned
excessively close to the air bag.

Why Didn’t My Air Bag Go Off
in a Collision? (Air bags are
not designed to inflate in
every collision.)
There are certain types of accidents
in which the air bag would not be
expected to provide additional protec-
tion. These include rear impacts, sec-
ond or third collisions in multiple
impact accidents, as well as low
speed impacts. Damage to the vehicle
indicates a collision energy absorp-
tion, and is not 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 or
death.
Always properly restrain chil-
dren in an appropriate child
restraint 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 are
installed.
(Continued)
(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.
Press the Engine Start/Stop
button to the OFF or ACC
position when the vehicle is
being towed to prevent inad-
vertent air bag deployment.
Have all air bag repairs con-
ducted by an authorized
HYUNDAI dealer.

Air bag inflation conditions
Front air bag
Front air bags are designed to inflate
in a frontal collision depending on
the intensity, speed, or angles of
impact of the front collision.
Side impact and curtain air bags
Side impact and curtain air bags are
designed to inflate when an impact is
detected by side collision sensors
depending on the strength, 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
impact and curtain air bags are
designed to inflate only in side
impact collisions or rollover situa-
tions, 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.

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 impact and curtain air
bags may inflate when the vehicle is
rolled over by a side impact collision,
if the vehicle is equipped with side air
bags and curtain air bags.
Also, if the vehicle is equipped with a
rollover sensor, side impact and cur-
tain air bags may inflate in a rollover.
