System
Information
The sensor that activates the SRS air
bag is connected with the pre–tension-
er seat belts. The SRS air bag warning
light on the instrument panel will illu-
minate for approximately 6 seconds
after the engine Start/Stop button in
the ON position, and then it should
turn off.
If the pre-tensioner is not working
properly, the warning light will illumi-
nate even if the SRS air bag is not mal-
functioning. If the warning light does
not illuminate, stays illuminated or
illuminates when the vehicle is being
driven, have an authorized retailer of
Genesis Branded products inspect the
pre-tensioner seat belts and SRS air
bags as soon as possible.

NOTICE
(Continued)
Always replace your pre-ten-sioners after activation or an
accident.
NEVER inspect, service, repair or replace the pre-ten-
sioners yourself. This must be
done by an authorized retailer
of Genesis Branded products.
Do not hit the seat belt assem- blies.
Do not touch the pre-tensioner
seat belt assemblies for several
minutes after they have been
activated. When the pre-ten-
sioner seat belt mechanism
deploys during a collision, the
pre-tensioners become hot and
can burn you.

Safety system of your vehicle
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
and front passenger's seat belt
usage and impact severity.
The seat belt buckle sensors deter-
mine if the driver and front passen-
ger's seat belts are fastened. These
sensors provide the ability to control
the SRS deployment based on
whether or not the seat belts are fas-
tened, 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 pro-
vided 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. 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.
Do not allow the front passen- ger to place their feet or legs
on the dashboard.
No objects (such as crash pad cover, cellular phone holder,
cup holder, perfume or stick-
ers) should be placed over or
near the air bag modules on
the steering wheel, instrument
panel, windshield glass, and
the front passenger's panel
above the glove box. Such
objects could cause harm if
the vehicle is in a crash
severe enough to cause the
air bags to deploy.
Do not attach any objects on front windshield and inside
mirror.

Side air bags
Your vehicle is equipped with a side
air bag in each front seat and out-
board rear 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 only during certain side impact
collisions, depending on the crash
severity, angle, speed and point of
impact.
The side and curtain air bags on both
sides of the vehicle may deploy if a
rollover or possible rollover is detect-
ed.
For vehicles equipped with a rollover
sensor the side air bags and pre-ten-
sioners on both sides of the vehicle
may deploy if a rollover or possible
rollover is detected. However, the
side air bags are not designed to
deploy in all side impact or rollover
situations.

To reduce the risk of serious
injury or death from an inflating
side 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 posi-
tions, 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.

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 pro-
vide adequate restraint. When need-
ed, the side air bags help provide
protection in the event of a side
impact or rollover.
Air bags are activated (able toinflate if necessary) only when the
engine Start/Stop button is in the
ON position.
Air bags inflate in the event of cer- tain 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.
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 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 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.
You can take steps to help reduce
the risk of being injured by an inflat-
ing air bag. The greatest risk is sitting
too close to the air bag. An air bag
needs about 10 inches (25 cm) of
space to inflate. NHTSA recom-
mends that drivers allow at least 10
inches (25 cm) between the center of
the steering wheel and the chest.

Safety system of your vehicle
Noise and smoke from inflatingair 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 deploy-
ment, seek medical attention imme-
diately.
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)
Your vehicle is equipped with an
Occupant Classification System
(OCS) in the front passenger's seat.
The Occupant Classification System
sensor, which is equipped inside the
front passenger’s seat, distinguishes
whether the seat is occupied by an
adult or a child restraint system, and
sends this information to the ACU.
Then, the ACU integrates this infor-
mation with any impact information
while determining whether to deploy
the air bags for the front passenger’s
seat.
- The Occupant Classification
System properly detects a front
passenger, when a passenger sits
in upright position. In an accident, it
properly deploys the air bag.
- The Occupant Classification System detects a child restraint
system, which is installed on the
front passenger's seat. In this
case, the air bag system for the
front passenger's seat gets dis-
abled.
- The Occupant Classification System may not deploy the air bag
for the front passenger's seat,
when a tiny adult sits out of upright
position.

Main components of theOccupant Classification System
A detection device located within
the front passenger seat cushion.
Electronic system to determine whether the passenger air bag sys-
tems should be activated or deacti-
vated.
An indicator light located on the instrument panel which illuminates
the words "PASSENGER AIR BAG
OFF" indicating the front passen-
ger air bag system is deactivated.
The instrument panel air bag indi- cator light is interconnected with
the OCS. The purpose is to help reduce the
risk of injury or death from an inflat-
ing air bag to certain front passenger
seat occupants, such as children, by
requiring the air bag to be automati-
cally 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.
Always be sure that you and all vehi-
cle occupants are seated properly
and wearing the seat belt properly for
the most effective protection by the
air bag and the seat belt.

Do not sit on the passenger seat wearing heav-ily padded clothes such as ski wear and hip
protector.
Do not use car seat accessories such as thick blankets and cushions which cover up the car
seat surface.
Do not place electronic devices such as lap- tops, 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 charg-
ers.
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 com-
pletely 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
Genesis Branded products 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.

Air bag inflation conditions
Front air bags
Front air bags and the driver's knee
air bag are designed to inflate in a
frontal collision depending on the the
severity of impact of the front colli-
sion.
OHI036059
To reduce the risk of an air bag
deploying unexpectedly and
causing serious injury or death:
Do not hit or allow any objectsto impact the locations where
air bags or sensors are
installed.
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-Genesis/Hyundai Part.
This may adversely affect the
collision and air bag deploy-
ment performance.
Place the engine Start/Stop button in 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
retailer of Genesis Branded
products.
