The Occupant Classification System (OCS)
automatically turns the front passenger front
air bag on or off based on the classified
occupant weight category determined by
weight sensor readings from the front

bag, the window curtain air bag and the
Emergency Tensioning Devices (ETDs).
Occupants must sit with the seat belt
properly fastened in a position that is as
upright as possible with their back against the
seat backrest and feet on the floor to be

(e.g. by leaning on armrests), the OCS may
not be able to properly approximate the
occupant’s weight category.

5/ indicator lamp goes out.

unit will not allow front passenger front air
bag deployment when the OCS has
