■Front passenger occupant classification system precautions
Observe the following precautions regardin g front passenger occupant classifica-
tion system. 
Failure to do so may cause death or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s seat belt tab has not been left inserted into the
buckle before someone sits in the front passenger seat.
●Make sure the AIRBAG OFF indicator lights is not illuminated when using the
seat belt extender for the front pass enger seat. If the AIRBAG OFF indicator
light is illuminated, disconnect the extender tongue from the seat belt buckle,
then reconnect the seat belt. Reconnect the seat belt extender after making sure
the AIRBAG ON indicator light is illuminated. If you use the seat belt extender
while the AIRBAG OFF indicator light is il luminated, the front passenger airbag,
side airbag on the front passenger side and front passenger knee airbag may not
activate correctly, which could cause death or serious injury in the event of colli-
sion.
●Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seatback from the rear passenger seat.
●Do not let a rear passenger lift the front passenger seat with their feet or press on
the seatback with their legs.
●Do not put objects under the front passenger seat.
●Do not recline the front passenger seatback so far that it touches a rear seat. This
may cause the AIRBAG OFF indicator light to be illuminated, which indicates
that the passenger’s airbags will not deploy in the event of a severe accident. If the
seatback touches the rear se at, return the seatback to a position where it does
not touch the rear seat. Keep the front pa ssenger seatback as upright as possible
when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.
●If an adult sits in the front passenger se at, the AIRBAG ON indicator light is illu-
minated, If the AIRBAG OFF indicator is il luminated, ask the passenger to sit up
straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the AIRBAG OFF indicator still remain illuminated, either ask the pas-
senger to move to the fear seat, or if that is not possible, move the front passenger
seat fully rearward.
