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.

passenger seat, the system may recognize him/her as a child depending on his/her physique
and posture.
*
2Do not allow children to ride in the front passenger seat. When a larger child who has out-
grown a child restraint system sits in the front passenger seat, the system may recognize
him/her as an adult depending upon his/her physique or sitting position.
*
3Never install a child restraint system on the front passenger seat.
*4The PASSENGER AIR BAG "OFF" indicator may turn on or off when a child above 12 months
to 12 years old (with or without child restraint system) sits in the front passenger seat. This is
a normal condition.

Riding in an improper position or placing weight on the front passen-
ger's seat when it is unoccupied by a passenger adversely affects the
OCS. To reduce the risk of serious injury or death:

• NEVER put a heavy load in the front seat or
seatback pocket, or hang any items on the
front passenger seat.
• NEVER place your feet on the front passenger
seatback.
• NEVER sit with your hips shifted towards the
front of the seat.
• NEVER ride with the seatback reclined when
the vehicle is moving.
• NEVER place your feet or legs on the dash-
board.
• NEVER lean on the door or center console or
sit on one side of the front passenger seat.

• 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.

Proper seated position for OCS
If the "PASSENGER AIR BAG OFF"
indicator is on when an adult is seat-
ed in the front passenger seat, place
the Engine Start/Stop button in the
OFF position and ask the passenger
to sit properly (sitting upright with the
seat back in an upright position, cen-
tered on the seat cushion with their
seat belt on, legs comfortably
extended and their feet on the floor).
Restart the engine and have the per-
son remain in that position. This will
allow the system to detect the person
and to enable the passenger air bag.
If the "PASSENGER AIR BAG OFF"
indicator is still on, ask the passen-
ger to move to the rear seat.
Information
The "PASSENGER AIR BAG OFF"
indicator illuminates for approximate-
ly 4 seconds after the Engine Start/
Stop button is in the OFF position or
after the engine is started. If the front
passenger seat is occupied, the OCS
will then classify the front passenger
after several more seconds.
i
Never allow an adult passenger
to ride in the front passenger
seat when the "PASSENGER
AIR BAG OFF" indicator is illu-
minated. During a collision, the
air bag will not inflate if the indi-
cator is illuminated. Have your
passenger reposition himself in
the seat. If the "PASSENGER
AIR BAG OFF" indicator
remains illuminated after the
passenger repositions himself
properly and the vehicle is
restarted, have the passenger
move to the rear seat because
the air bag will not inflate.

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.
