Hyundai Palisade: Occupant Classification
System (OCS) / 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
instrument panel which illuminates
the words “OFF” and symbol 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, sensor can help 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 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 center
fascia 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 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.
Condition and operation in the front passenger Occupant Classification
System

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:

- NEVER put a heavy load in
the front seat or seatback
pocket.

- 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 dashboard.

- 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 heavily
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 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.

- 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.

Proper seated position for OCS
If the "PASSENGER AIR BAG OFF"
indicator 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 themself in the
seat. If the "PASSENGER AIR
BAG OFF" indicator remains illuminated
after the passenger
repositions themself 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 illuminates for approximately
4 seconds after the Engine
Start/Stop button is in the ON
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.
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...
