Child Seat or Child Judgment

► If the judgment value is lower than criteria value B and the seat belt buckle switch is ON, the occupant classification ECU judges that a child seat is installed.

► If the judgment value is higher than criteria value A, but lower than criteria value B, and the seat belt buckle switch is OFF, the occupant classification ECU judges that the seat is being occupied by a child.

► When the ignition*1 / engine*2 switch is turned ON under these conditions, the system performs an initial check and illuminates the AIRBAG OFF indicator light to indicate that the front passenger airbag and the front passenger side airbag have been deactivated.
