Safety system of your vehicle
The Pre-Tensioner Seat Belt System
consists mainly of the following com-
ponents. Their locations are shown in
the illustration above:
1. SRS air bag warning light
2. Retractor pre-tensioner
3. SRS control module
4. Emergency Fastening Device
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.
Information
• Both the driver's and front passen-
ger'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 condi-
tions 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
retailer of Genesis Branded prod-
ucts. The air bag warning light illu-
minates, if there is a malfunction
with the pre-tensioner seat belt sys-
tem.
• In following situations, immediately
have the air bag system and the pre-
tensioner seat belt system checked
by an authorized retailer of Genesis
Branded products.
- The air bag warning light does not
illuminate at all after turning ON
the engine.
- The air bag warning light remains
ON over 6 seconds after turning
ON the engine.

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.

Side air bags
Your vehicle is equipped with a side
air bag in each front seat and out-
board rear seats. 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.
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.

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 (front)
4. Side air bag modules (rear)
5. Curtain air bag modules
6. Retractor pre-tensioner assemblies
7. Air bag warning light
8. SRS control module (SRSCM)
/ Rollover sensor
9. Front impact sensors
10. Side impact sensors
(acceleration)
11. Side impact sensors (pressure)
12. Driver's knee air bag module
13. Emergency fastening device
14. Occupant classification system
15. Driver's and front passenger's
seat belt buckle sensors
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-ten-
sioner seat belt deployment. 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 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.

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 to
inflate if necessary) only when the
Engine Start/Stop button is in the
ON or START 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.
• 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.

Main components of the
Occupant Classification System
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 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.
Front passenger seat adult occu-
pants who are properly seated and
wearing the seat belt properly,
should not cause the passenger air
bag to be automatically turned OFF.
For small adults it may be turned
OFF, however, if the occupant does
not sit in the seat properly (for exam-
ple, by not sitting upright, by sitting
on the edge of the seat, or by other-
wise 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. 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 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.
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 a thick cloth like ski wear
or hip protection wear.
• Putting an additional thick cushion
on the seat.
• Putting electrical devices (e.g.
notebook, satellite radio) on the
seat with inverter charging.

• 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 classification 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.

Safety system of your vehicle
Do Not Install a Child Restraint
in the Front Passenger's Seat
Even though your vehicle is
equipped with the OCS, never install
a child restraint in the front passen-
ger’s seat. An inflating air bag can
forcefully strike a child or child
restraint resulting in serious or fatal
injury.
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 pro-
vide additional protection. These
include rear impacts, second or third
collisions in multiple impact acci-
dents, 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.
• NEVER place a rearward-fac-
ing or forward-facing child
restraint in the front passen-
ger'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
OHI039193N
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 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 Genesis Part.
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
retailer of Genesis Branded
products.

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.
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 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 and
curtain air bags are designed to
inflate only in side impact collisions
or rollover situations, but they may
inflate in other collisions if the side
impact sensors detect a sufficient
impact.
