*1: The system judges a person of adult size as an adult. When a smaller adult sits
in the front passenger seat, the system may recognize him/her as a child
depending on his/her physique and posture.
*2: In the event the front passenger does not wear a seat belt
*3: When a larger child who has outgrown a child restraint system sits in the front
passenger seat, the system may recognize him/her as an adult depending on
his/her physique or posture.
*4: Never install a rear-facing child restraint system on the front passenger seat. A
forward-facing child restraint system should only be installed on the front pas-
senger seat when it is unavoidable. ( P. 72)
*5: In case the indicator light is not illuminated, consult this manual on how to
install the child restraint system properly. ( P. 89)
*6: Activated only in cases of side impact
CAUTION
■Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classi-
fication system.
Failure to do so may cause death or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s seat belt plate has not been left inserted into the
buckle before someone sits in the front passenger seat.
●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.

CAUTION
■Front passenger occupant classification system precautions
●Do not recline the front passenger seatback so far that it touches a rear seat. This
may cause the “AIR BAG 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 seat, return the seatback to a position where it does
not touch the rear seat. Keep the front passenger 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 seat, the “AIR BAG ON” indicator light is illu-
minated. If the “AIR BAG OFF” indicator is illuminated, 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 “AIR BAG OFF” indicator still remains illuminated, either ask the pas-
senger to move to the rear seat, or if that is not possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a forward-facing child restraint system on the
front passenger seat, install the child restraint system on the front passenger seat
in the proper order. ( P. 89)
●Do not modify or remove the front seats.
●Do not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indicate a malfunction of the detection sys-
tem. In this case, contact your Lexus dealer immediately.
●Child restraint systems installed on the rear seat should not contact the front seat-
backs.
●Do not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.
●Do not modify or replace the upholstery of the front seat.

CAUTION
■When installing a child restraint system
For safety reasons, always install a child restraint system in a rear seat. In the event
that the rear seat cannot be used, the front seat can be used as long as the airbag
manual on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag deploy-
ment (inflation) may cause serious injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on.
If it is left off, the airbag may not deploy in the event of an accident, which may
result in serious injury or even death.
