The Pre-Tensioner Seat Belt System
consists mainly of the following
components. Their locations are shown
in the illustration above:
(1) SRS air bag warning light
(2) Front retractor pre-tensioner
(if equipped)
(3) SRS control module
OBC3030012R
„Rear
(4) Rear retractor pre-tensioner
(if equipped)
NOTICE
The sensor that activates the SRS
air bag is connected with the pre–
tensioner seat belts. The SRS air bag
warning light on the instrument panel
will illuminate for approximately 6
seconds after the ignition switch is
placed to the ON position, and then it
should turn off.
If the pre-tensioner is not working
properly, the warning light will
illuminate even if the SRS air bag is not
malfunctioning. If the warning light
does not illuminate, stays illuminated
or illuminates when the vehicle is
being driven, we recommend the pre-
tensioner seat belts and/or SRS air bags
be inspected by a HYUNDAI authorised
repairer as soon as possible.

How does the air bags system
operate?
OBC3030023R
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)
(8) Front impact sensors
(9) Side impact sensors*
(10) Side pressure sensors*
(11) Passenger’s front air bag OFF
indicator (front passenger’s seat
only) *
(12) Passenger’s front air bag ON/OFF
switch *
* : if equipped
The SRSCM continually monitors SRS
components whilst the ignition switch
is in the ON 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 problem with your air
bag system.
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
ignition switch is in the ON position.

[The light stays on after illuminating
for approximately six seconds.

[The light comes on whilst the vehicle
is in motion.

[The light blinks when the engine is
running.
We recommend that a HYUNDAI
authorised repairer 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,
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.

[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 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 and it’s 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.
[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 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 centre of the
steering wheel and the chest whilst still
maintaining control of the vehicle.

Safety system
Do not install a Child Restraint
System on the front passenger
seat
OHI038169L
Never install a Child Restraint System in
the front passenger’s seat. An inflating air
bag can forcefully strike a child or restraint
resulting in serious or fatal injury.
WARNING

[Extreme hazard! Do not use a
rearward facing Child Restraint
System on a seat protected by an air
bag in front of it!

[NEVER use a rearward facing Child
Restraint System on a seat protected
by an ACTIVE AIRBAG in front of it,
DEATH or SERIOUS INJURY to the
CHILD can occur.

[Never put a Child Restraint System in
the front passenger’s seat. If the front
passenger air bag inflates, it would
cause serious or fatal injuries.
Why didn’t my air bag go off in a
collision?
There are certain types of accidents in
which the air bag would not be expected
to provide additional protection. These
include rear impacts, second or third
collisions in multiple impact accidents,
as well as low speed impacts. Damage to
the vehicle indicates a collision energy
absorption, and is not an indicator of
whether or not an air bag should have
inflated.
Air bag collision sensors
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.

[Do not perform maintenance on or
around the air bag sensors. 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.

[Installing bumper guards with non-
genuine Hyundai or non-equivalent
parts may adversely affect the
collision and airbag deployment
performance.
To ensure correct function of the
airbag system we recommend to
replace the bumper with genuine
HYUNDAI part or the equivalent (of
the genuine part) specified for your
vehicle.

[Place the ignition switch to the
LOCK/OFF or ACC position, when the
vehicle is being towed to prevent
inadvertent air bag deployment.

[We recommend that all air bag
repairs are conducted by a HYUNDAI
authorised repairer.

Air bag inflation conditions
OBC3030027
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on the
severity of impact of the front collision.
OBC3030028R
OAC3039029R
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 impact resulting from
a side impact collision. Although the
driver’s and front passenger’s air bags
are designed to inflate only in frontal
collisions, they also may inflate in other
types of collisions if the front impact
sensors detect a sufficient impact. Side
and curtain air bags are designed to
inflate only in side impact collisions, 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.
