*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 large child who has outgrown a child restraint system sits in
the front passenger seat, the sys tem may recognize him/her as an
adult depending on his/her physique and posture.
*4: Never install a rear-facing child restraint system on the front passen-
ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. 
( P. 152)
*5: In case the indicator li ght is not illuminated, consult this manual on
how to installing the child restraint system properly. ( P. 147)
CAUTION
■Front passenger occupant classi fication system precautions
Observe the following precautions regarding the front passenger occupant classifi-
cation 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.

CAUTION
■Front passenger occupant classification system precautions
●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, disconnect the extender tongue from the seat belt buckle, and
reconnect the seat belt. Reconnect the 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 front passenger airbag
and front passenger knee airbag 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 pocket).
●Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seat back from the second seat.
●Do not let a second seat 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 second seat.
This may cause the “AIR BAG OFF” indicato r light to be illuminated, which indi-
cates that the passenger’s airbags will not deploy in the event of a severe acci-
dent. If the seatback touche s the second seat, return the seatback to a position
where it does not touch the second seat. Keep the front passenger seatback as
upright as possible when the vehicle is moving. Reclining the seatback exces-
sively may lessen the effectiveness of the seat belt system.

CAUTION
●If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illu-
iminated. 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 remain illuminated, either ask the pas-
senger to move to the rear seat, or if th at 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. 1 5 2 )
●Do not modify or remove the front seat.
●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 in the detection sys-
tem. In this case, contact your Lexus dealer immediately.
●Child restraint systems installed on the second seat should not contact the front
seatbacks.
●Do not use a seat accessory, such as a cushion and seat cover, that covers the
seat cushion surface.
●Do not modify or replace the upholstery of the front seat.

Child restraint systems
Points to rememberStudies have shown that installing a ch ild restraint on a rear seat is much
safer than installing one to 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 ins tructions provided with the child
restraint system. 
General installation instructions are provided in this manual. (P. 1 5 2 )
A child restraint system for a small child or baby must itself be properly
restrained on the seat with 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.

■Selecting an appropriate child restraint system
●Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the vehicle’s seat belt.
●If the child is too large for a child restraint system, sit the child on a rear seat and
use the vehicle’s seat belt. (P. 8 6 )
CAUTION
■Child restraint precautions
●For effective protection in automobile ac cidents and sudden stops, a child must
be properly restrained, using a seat belt or child restraint system depending on
the age and size of the child. Holding a child in your arms is not a substitute for a
child restraint system. In an accident, the child can be crushed against the wind-
shield, or between you and the vehicle’s interior.
●Lexus strongly urges the use of a proper child restraint system that conforms to
the size of the child, installed on the rear seat. According to accident statistics, the
child is safer when properly restrained in the rear seat than in the front seat.
●Never install a rear-facing child restraint system on the front passenger seat even
if the “AIR BAG OFF” indicator light illuminated. In the event of an accident, the
force of the rapid inflation of the front passenger airbag can cause death or seri-
ous injury to the child if the rear-facing child restraint system is installed on the
front passenger seat.

CAUTION
■Child restraint precautions
●A forward-facing child restraint system may be installed on the front passenger
seat only when it is unavoidable. A child restraint system that requires a top tether
strap should not be used in the front passenger seat since there is no top tether
strap anchor for the front passenger seat. Adjust the seatback as upright as possi-
ble and always move the seat as far back as possible even if the “AIR BAG OFF”
indicator light is illuminated, because the front passenger airbag could inflate with
considerable speed and force. Otherwise, the child may be killed or seriously
injured.
●Do not use the seat belt extender when installing a child restraint system on the
front or rear passenger seat. If installing a child restraint system with the seat belt
extender connected to the seat belt, the seat belt will not securely hold the child
restraint system, which could cause death or serious injury to the child or other
passengers in the event of collision.
●Do not allow the child to lean his/her head or any part of his/her body against the
door or the area of the seat, front, center and rear pillars or roof side rail from
which the SRS side airbags or SRS curtain shield airbags deploy even if the child
is seated in the child restraint system. It is dangerous if the SRS side airbags and
curtain shield airbags inflate, and the imp act could cause death or serious injury
to the child.
●Make sure you have complied with all inst allation instructions provided by the
child restraint manufacturer and that the sy stem is properly secured. If it is not
secured properly, it may cause death or serious injury to the child in the event of a
sudden stop or accident.
