*1: The system judges a person of adult size as an adult. When a smaller adult sitsin 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 ch ild restraint system sits in the front
passenger seat, the system may recogn ize 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 shou ld only be installed on the front pas-
senger seat when it is unavoidable. ( P. 6 2 )
*5: In case the indicator light is not illumi nated, consult this manual on how to
install the child restraint system properly. ( P. 66)

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.
●Make sure the “AIR BAG OFF” indicator li ght is not illuminated when using the
seat belt extender for the front passen ger seat. If the “AIR BAG OFF” indicator
light is illuminated, discon nect the extender tongue from the seat belt buckle,
then reconnect the seat belt. Reconnect th e seat belt extender after making sure
the “AIR BAG ON” indicator light is illuminated. If you use the seat belt extender
while the “AIR BAG OFF” indicator light is illuminated, the SRS airbags for the
passenger may not activate correctly, which could cause death or serious injury
in the event of a collision.
●Do not apply a heavy load to the front passenger seat or equipment (e.g. seat-
back pockets or armrest).
●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 th e 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 th e “AIR BAG OFF” indicator is illumi nated, 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 stil l 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 rest raint system on the front passenger seat
in the proper order. ( P. 66)
●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 indi cate 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.

It is recommended that children sit in
the rear seats to avoid accidental
contact with the shift lever, wiper switch etc.
●Use the rear door child-protector lo ck or the window lock switch to
avoid children opening the door wh ile driving or operating the power
window accidentally.
●Do not let small children operate eq uipment which may catch or pinch
body parts, such as the power window, hood, trunk, seats etc.
Safety information for children
Observe the following precautions when children are in the vehicle.
Use a child restraint system approp riate for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt.
CAUTION
Never leave children unattended in the vehicle, and never allow children to have or
use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the cigarette
lighter, the windows, the moon roof, or ot her features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal to chil-
dren.

Studies have shown that installing a child restraint on a rear seat is much
safer than installing one on the front passenger seat.
●Choose a child restraint system that suits your vehicle and is appropri-
ate to the age and size of the child.
●For installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual. ( P. 6 6 )
Child restraint systems
A child restraint system for a small ch ild or baby must itself be properly
restrained on the seat with the LATCH anchors or the lap portion of the
lap/shoulder belt.
The laws of all 50 states of the U .S.A. and Canada now require the use
of child restraint systems.
