■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller adult sits in thefront passenger seat, the system may not recognize him/her as an adult depending on
his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt.
*4: For some children, child in seat, child in bo oster seat or child in convertible seat, the
system may not recognize him/her as a child. Factors which may affect this can be the
physique or posture.
*5: Never install a rear-facing child restraint system on the front passenger seat. A for-
ward-facing child restraint syst em should only be installed on the front passenger seat
when it is unavoidable. ( P. 59)

WARNING
■Front passenger occupant classification system precautions
Observe the following precautions regarding the 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 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 passenger seat. If the “AIR BAG OFF” indicator light is illu-
minated, 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 SRS airbags for the front passenger will not
activate, which could cause death or seri ous injury in the event of a collision.
●Do not apply a heavy load to the front passenger seat or equipment (e.g. seatback
pocket).
●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.

WARNING
■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
SRS airbags for the front passenger will no t activate 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 effec-
tiveness of the seat belt system.
●If an adult sits in the fron t passenger seat, the “AIR BAG ON” indicator light is illumi-
nated. 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 correctly. If
the “AIR BAG OFF” indicator still remains illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the front passenger seat fully
rearward.
●When it is unavoidable to in stall a forward-facing child re straint system on the front
passenger seat, install the ch ild restraint system on the front passenger seat in the
proper order. ( P. 61)
●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 front passenger
occupant classification system. In this cas e, 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 and seat cover, that covers the seat
cushion surface.
●Do not modify or replace the upholstery of the front seat.

RX450h_U_OM0E013U1-2. Child safety
●It is recommended that children sit in the rear seats to avoid accidental con-
tact with the shift lever, wiper switch, etc.
●Use the rear door child-pro
tector lock or the window lock switch to avoid
children opening the door while driving or operating the power window acci-
dentally.
●Do not let small children operate equipment which may catch or pinch body
parts, such as the power wind ow, hood, back door, seats etc.
Riding with children
Observe the following precautions when children are in the vehicle.
Use a child restraint system appropriate for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt.
WARNING
Never leave children unattended in the vehicl e, and never allow children to have or use
the key.
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by playing with the windows, the moon roof
or panoramic moon roof, or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.

WARNING
■When a child is riding
Observe the following precautions.
Failure to do so may result in death or serious injury.
●For effective protection in automobile accidents and sudden stops, a child must be
properly restrained, using a seat belt or child restraint system which is correctly
installed. For installation details, refer to the operation manual enclosed with the child
restraint system. General installation instruction is provided in this manual.
●Lexus strongly urges the use of a proper ch ild restraint system that conforms to the
weight and size of the child, installed on the rear seat. According to accident statistics,
the child is safer when properly restrained in the rear se at than in the front seat.
●Holding a child in your or someone else’s arms is not a substitute for a child restraint
system. In an accident, the child can be crushed against the windshield or between
the holder and the interior of the vehicle.
■Handling the child restraint system
If the child restraint system is not properly fixed in place, the child or other passengers
may be seriously injured or even killed in th e event of sudden braking, sudden swerv-
ing, or an accident.
●If the vehicle were to receive a strong impact from an accident, etc., it is possible that
the child restraint system has damage that is not readily visible. In such cases, do not
reuse the restraint system.
●Make sure you have complied with all installa tion instructions provided with the child
restraint system manufacturer and th at the system is properly secured.
●Keep the child restraint system properly secure d on the seat even if it is not in use. Do
not store the child restraint system un secured in the passenger compartment.
●If it is necessary to detach the child rest raint system, remove it from the vehicle or
store it securely in the luggage compartment.

WARNING
■When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Never install a rear-facing child restraint system on the front passenger seat even if
the “AIR BAG OFF” indicator light is illuminated. In the even t of an accident, the force
of the rapid inflation of the front passenger airbag can cause death or serious injury to
the child if the rear-facing ch ild restraint system is installed on the front passenger
seat.
●A forward-facing child restraint system ma y 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.
●A forward-facing child restraint system may
be installed on the front passenger seat only
when it is unavoidable. When installing a for-
ward-facing child restraint system on the front
passenger seat, raise the seatback as much as
possible, move the seat to the rearmost posi-
tion, and raise the seat to the highest position,
even if the “AIR BAG OFF” indicator light is
illuminated.
If the head restraint interferes with the instal-
lation of the child restraint system, and the
head restraint can be removed, remove the
head restraint.
If the head restraint cannot be removed, raise
it to the uppermost position.
●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 or rear pillars, or
roof side rails from which the SRS side air-
bags or SRS curtain shield airbags deploy
even if the child is seat ed in the child restraint
system. It is dangerous if the SRS side airbags
and curtain shield airbags inflate, and the
impact could cause death or serious injury to
the child.
