CAUTION
Body work on the front area of the
vehicle may damage the pre-tensioner
seat belt system. Therefore, have the
system be serviced by an authorized
HYUNDAI dealer.
The Pre-Tensioner Seat Belt System
consists mainly of the following
components. Their locations are shown
in the illustration:
B0702EU01
M SRS air bag warning light
N Retractor pre-tensioner
O SRS control module
NOTICE
The sensor that activates the SRS
control module is connected with the
pre–tensioner seat belts. The SRS air
bag warning light on the instrument
cluster will illuminate for approximately
3~6 seconds after the ignition switch is
in 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, have the pre-tensioner
seat belts and/or SRS control module
inspected by an authorized HYUNDAI
dealer as soon as possible.
Information

[ Both the driver's and front passenger's
pre-tensioner seat belts may be
activated in certain frontal or side
collisions or rollovers.

[ When the pre-tensioner seat belts are
activated, a loud noise may be heard
and fine dust, which may appear to be
smoke, may be visible in the passenger
compartment. These are normal
operating conditions and are not
hazardous.

[ Although it is non-toxic, the fine dust
may cause skin irritation and should
not be inhaled for prolonged periods.
Wash all exposed skin areas thoroughly
after an accident in which the pre-
tensioner seat belts were activated.

[ The pre-tensioner seat belt system may
get adversely affected by installing an
audio system to the center console or
welding/painting the frontal vehicle
body.
In this case, consult an authorized
HYUNDAI dealer. The air bag
warning light illuminates, if there is a
malfunction with the pre-tensioner seat
belt system.

[ In following situations, immediately
have the air bag system and the pre-
tensioner seat belt system checked by
an authorized HYUNDAI dealer.

- The air bag warning light does not
illuminate at all after turning ON the
engine

- The air bag warning light remains
ON over 3~6 seconds after turning
ON the engine

Where Are the Air Bags?
Driver’s and passenger’s front air
bags
B0071KO01
B0071KO02
B0072EE01
A: Driver’s front air bag, B: Driver’s knee air bag,
C: Passenger’s front air bag
Your vehicle is equipped with an
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 steering
wheel, in the driver’s side lower crash
pad below the steering wheel, and the
passenger’s side front panel pad above
the glove box.
The air bags are labeled with the letters
“AIR BAG” embossed on the pad covers.
The purpose of the SRS is to provide the
vehicle’s driver and front passengers with
additional protection than that offered
by the seat belt system alone in case of a
frontal impact of sufficient severity.
The SRS uses sensors to gather
information about the driver’s and front
passenger's seat belt usage and impact
severity.
The seat belt buckle sensors determine
if the driver and front passenger's seat
belts are fastened. These sensors provide
the ability to control the SRS deployment
based on whether or not the seat belts
are fastened, and how severe the impact
is.
The advanced SRS offers the ability to
control the air bag inflation within two
levels. A first stage level is provided for
moderate-severity impacts. A second
stage level is provided for more severe
impacts.
According to the impact severity, and
seat belt usage, the SRS Control Module
(SRSCM) controls the air bag inflation.
Failure to properly wear seat belts can
increase the risk or severity of injury in an
accident.

How Does the Air Bags System
Operate?
B0067EU05
The SRS consists of the following
components:
M Driver’s front air bag module
N Passenger’s front air bag module
O Side air bag modules
P Curtain air bag modules
Q Front retractor pre-tensioner
R Air bag warning light
S SRS control module (SRSCM) / Rollover sensor
T Front impact sensors
U Side impact sensors (acceleration)
V Side impact sensors (pressure)
Driver’s knee air bag module
Occupant Classification System (OCS)
Information
Front passenger’s air bag OFF lamp is
located on the overhead console. The SRSCM (Supplemental Restraint
System Control Module) 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 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 three to six seconds
when the ignition switch 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. 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 ignition
switch 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.

[ Generally, air bags are designed to
inflate based upon the severity of a
collision, its direction, or 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.

Seats & Safety System3-68

[ 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, 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 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. 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.

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.

[
NEVER lean on the door or center console or sit on
one side of the front passenger seat.
B0073KO09

[Do not sit on the passenger seat wearing heavily
padded clothes such as ski wear and hip protector.
B0073KO11

[Do not use car seat accessories such as thick blankets
and cushions which cover up the car seat surface.
B0073KO10

[Do not place electronic devices such as laptops, DVD
player, or conductive materials such as water bottles
on the passenger seat.

[ Do not use electronic devices such as laptops and
satellite radios which use inverter chargers.
B0073KO12

[If large quantity of liquid has been spilled on the
passenger seat, the air bag warning light may
illuminate or malfunction.
Therefore, make sure the seat has been completely
dried before driving the vehicle.

[ Do not place sharp objects on the front passenger seat. These may damage the
occupant detection system, if they puncture the seat cushion.

[ Do not place any items under the front passenger seat.

[ When changing or replacing the seat or seat cover, use original items only.
The OCS has been developed based on using original HYUNDAI car seats only.
Altering or changing the authentic parts may result in system malfunction and
increase risk of injury when in collision. Any of the above could interfere with the
proper operation of the OCS sensor thereby increasing the risk of an injury in an
accident.

Seats & Safety System
Do not install a Child Restraint
System on the Front Passenger's
Seat
B0073EU02
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING

[
NEVER place a rearward-facing or
forward-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 children in
an appropriate child restraint in the
rear seat of the vehicle.
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.

[ Do not install bumper guards or
replace the bumper with a non-
genuine HYUNDAI parts. This may
adversely affect the collision and air
bag deployment performance.

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

[ Have all air bag repairs be conducted
by an authorized HYUNDAI dealer.
