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.

WARNING
Riding in an improper position or placing weight on the front passenger’s seat when
it is unoccupied by a passenger adversely affects the OCS. To reduce the risk of
serious injury or death:
B0073KO04

[NEVER put a heavy load in the front seat or seatback
pocket, or hang any items on the front passenger
seat.
B0073KO13

[NEVER place your feet on the front passenger
seatback.
B0073KO05

[NEVER sit with your hips shifted towards the front of
the seat.
B0073KO07

[NEVER ride with the seatback reclined when the
vehicle is moving.
B0073KO06

[NEVER place your feet or legs on the dashboard.

Seats & Safety System
B0073KO08

[
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.

B0073KO03
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
ignition switch 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
ignition switch is in the ON or START
position. But, if the ignition switch is
placed to the ON or START position
within 3 minutes after the engine is
turned 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.

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.

Air bag inflation conditions
B0076EU02
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.
B0076EU03
B0076EU04
Side and curtain air bags
Side and curtain air bags are designed
t
o 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
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 and
front center air bag 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 bag
are designed to inflate when a rollover is
detected by a 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.

3-79
Air bag non-inflation conditions
B0076EU02
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.
B0076EU05
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.
B0076EU06
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
and front center air bag may inflate
depending on the severity of impact.

Seats & Safety System3-80
B0076KO08
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.
B0076EU07
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.
B0076KO10
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
However, the side and curtain air bags
and front center air bag may inflate in a
rollover situation, when it is detected by
the rollover sensor.
B0076EU08
Air bags may not inflate if the vehicle
collides with objects such as utility poles
or trees, where the point of impact is
concentrated and the collision energy is
absorbed by the vehicle structure.
