Occupant Classification System
(OCS)
OCN7N031139NOCN7N031139N
OCN7030070NOCN7030070N
Your vehicle is equipped with an
Occupant Classification System (OCS) in
the front passenger’s seat.
Main components of the Occupant
Classification System
• A detection device located within the front passenger seat cushion.
• Electronic system to help determine whether the passenger air bag
systems should be activated or
deactivated.
• An indicator light located on the instrument panel which illuminates
the words “PASSENGER AIR BAG OFF”
indicating the front passenger air bag
system is deactivated.
• The instrument panel 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.

Seats & Safety System3-42
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 small adults it may be
turned 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.
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.
Never install a Child Restraint System in
the front passenger’s seat. If you should
install a CRS (Child Restraint System)
inevitably, use a forward-facing CRS with
3-point ALR safety seat belt and adjust
the front passenger’s seat as far to the
rear as possible. If the PASSENGER AIR
BAG “OFF” indicator is OFF after a CRS
(Child Restraint System) is equipped,
the front passenger’s airbag is operating
so you should install the CRS in the rear
seats of the vehicle immediately. 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 (for example, notebook, satellite radio) on
the seat with inverter charging.

OHI038162OHI038162
• If large amount 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.

Proper seated position for OCS
If the “PASSENGER AIR BAG OFF”
indica
tor is on when an adult is seated
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, centered
on the seat cushion with their seat belt
on, legs comfortably extended and their
feet on the floor). Restart the engine and
have the person 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 passenger to
move to the rear seat.
WARNING
NEVER allow an adult passenger to ride
in the front passenger seat when the
“PASSENGER AIR BAG OFF” indicator
is illuminated. During a collision, the
air bag will not inflate if the indicator
is illuminated. Have your passenger
reposition themselves in the seat. If the
“PASSENGER AIR BAG OFF” indicator
remains illuminated after the passenger
repositions themselves properly
and the vehicle is restarted, have
the passenger move to the rear seat
because the air bag will not inflate.
NOTICE
The “PASSENGER AIR BAG OFF”
indicator generally illuminates for
approximately 4 seconds after the
Engine Start/Stop button is in the ON
position or after the engine is started.
However, if the Engine Start/Stop
button is turned to the ON position
within 3 minutes after ignition OFF,
the indicator does not illuminate. If
the front passenger seat is occupied,
the OCS will then classify the front
passenger after several more seconds.

Do Not Install a Child Restraint in the
Front Passenger’s Seat
OHI039193NOHI039193N
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 rear-facing or front-
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?
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 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.
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.
• Press the Engine Start/Stop button
to the OFF or ACC position, when the
vehicle is being towed to prevent
inadvertent air bag deployment.
• Have all air bag repairs conducted by
an authorized HYUNDAI dealer.

Air bag inflation conditions
OCN7N031050LOCN7N031050L
Front air bags
Front air bags are designed to inflate
in a fr
ontal collision depending on the
severity of impact of the front collision.
OCN7N031049NOCN7N031049N
OCN7N031042OCN7N031042
Side and curtain air bags
Side and curtain air bags are designed to
infla
te when an impact is detected
by side collision sensors depending on
the severity, speed or angles of impact
resulting from a side impact collision.
Although the driver’s and front
passenger’s air bags are designed to
inflate 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 in side impact
collisions, but they may inflate in other
collisions if the side impact sensors
detect a sufficient impact.
Also, the side and curtain air bags are
designed to inflate when a rollover
is detected by a rollover sensor. (if
equipped with rollover sensor)
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.

Air bag non-inflation conditions
OCN7N031051LOCN7N031051L
In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide benefits
beyond the protection of the seat belts.
OCN7N031052LOCN7N031052L
Front air bags are not designed to inflate
in rear collisions, because occupants
are moved backward by the force of the
impact. In this case, inflated air bags
would not provide any additional benefit.
OCN7N031144NOCN7N031144N
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide additional
occupant protection.
However, side and curtain air bags may
inflate depending on the severity of
impact.
OCN7N031137NOCN7N031137N
In an angled collision, the force of impact
may direct the occupants in a direction
where the air bags would not be able to
provide any additional benefit, and thus
the sensors may not deploy any air bags.
