1-7. Safety information
■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 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 passen-
ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. (P. 77)
*5: In case indicator is not illuminated, consult this manual as for installing
the child restraint system properly. (P. 8 0 )

CAUTION
■Front passenger occupant classification system precautions
Observe the following precautions regarding 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 light is not illuminated when using the seat
belt extender for the front passenger 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 illuminated, the front passenger airbag, side
airbag on the front passenger side and front passenger knee airbag may not acti-
vate correctly, which could cause death or serious injury in the event of collision.
●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 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 AIRBAG ON indicator light is illu-
minated. If the AIRBAG 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 AIRBAG OFF indicator still remain 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.

CAUTION
■Front passenger occupant classification system precautions
●When it is unavoidable to install the 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. 8 0 )
●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.

Child restraint systems
Points to remember
Studies have shown that installing a child restraint on a rear seat is much
safer than installing one to the front passenger seat.
●Choose a child restraint system appropriate 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. 8 0 )
Types of child restraints
Child restraint systems are classified into the following 3 types according
to the age and size of the child.
Infant seat
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.

Booster seat
■When the child restraint system is not in use
Leave the child restraint system properly secured on the seat. Do not store the
restraint loosely on a passenger seat or in the trunk.
■Selecting an appropriate child restraint system
Get an appropriate child restraint system for the child. If a child is too large for a
child restraint system, sit the child on a rear seat and use the vehicle's seat belt.
(P. 3 4 )

CAUTION
■Child restraint precautions
●For effective protection in automobile accidents 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. In
the event of an accident, the force of the rapid inflation of the front passenger air-
bag can cause death or serious injury to the child if the rear-facing child restraint
system is installed on the front passenger seat.
●A forward-facing child restraint system should allowed to be installed on the front
passenger seat only when it is unavoidable. Always move the seat as far back as
possible, 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 pillar, rear pillar or roof side rail from which the
side airbags or curtain shield airbags deploy even if the child is seated in the child
restraint system. It is dangerous if the side airbags and curtain shield airbags
inflate, and the impact could cause death or serious injury to the child.
●Make sure you have complied with all installation instructions provided by the
child restraint manufacturer and that the system 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.
