Hyundai Palisade: Occupant Classification System (OCS) / Main components of the Occupant Classification System

Hyundai Palisade (LX2) 2020-2024 Owner's Manual / Safety System of Your Vehicle / Air Bag - Advanced Supplemental Restraint System / 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.

  • 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.
