■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 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 booster 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 system should only be installed on the front passenger
seat when it is unavoidable. ( P. 5 7 )
*6: In case the indicator light is not illuminated, consult this manual on how to install the
child restraint system properly. ( P. 5 9 )

■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 not 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 front 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 install a forward- facing child restraint system on the front
passenger seat, install the child restraint sy stem on the front passenger seat in the
proper order. ( P. 5 9 )
●Do not modify or remove the front seats.
●Do not kick the front passenger seat or subj ect it to severe impact. Otherwise, the
SRS warning light may come on to indicat e a malfunction of the front passenger
occupant classification system. In this ca se, 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 cu shion and seat cover, that covers the seat
cushion surface.
●Do not modify or replace the upholstery of the front seat.
●Do not place anything between the cons ole box and front passenger seat. Other-
wise, the system may not detect the front passenger properly, leading to improper
operation of the airbags.
●Adjust the front passenger seat so that the head restraint does not touch the ceiling. If
the head restraint is left in contact with th e ceiling, the system may not detect the front
passenger properly, leading to im proper operation of the airbags.

The laws of all 50 states of the U.S.A. as well as Canada now require the use of

●Prioritize and observe the warnings, as well as the laws and regulations for
child restraint systems.
●Choose a child restraint system that suits your vehicle and is appropriate to
the age and size of the child.
●Use a child restraint system appropriat e for the child until the child becomes

Child restraint systems
Before installing a child restraint system in the vehicle, there are precautions
that need to be observed, different type s of child restraint systems, as well as
installation methods, etc., written in this manual.
Use a child restraint system when riding with a small child that cannot properly
use a seat belt. For the child’s safety, install the child restraint system to a rear

■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 se at belt or child restraint system depending on the age
and size of the child.
●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 th e rear seat than in the front seat.
●Holding a child in your or someone else’s ar ms 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.
●Place one child to a child restraint system and then secure the child with the harness
of the child restraint system.
■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 that the system is properly secured.
●Keep the child restraint system properly secured on the seat even if it is not in use. Do
not store the child restraint system unsecured 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 trunk.

■When installing a child restraint system to a passenger seat
For the safety of a child, install child restraint systems to a rear seat. When

the passenger seat as follows and install the child restraint system.
●The seatback to the most upright
position
●Move the seat to the rearmost
position
●Raise the seat to the highest posi-
tion
●If the head restraint interferes
with the installation of the child
restraint system, and the head
restraint can be removed, remove

■When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Use child restraint system suitable to the age and size of the child and install it to the
rear seat.
●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, rear pillars or roof side rails from which the SRS curtain
shield airbag deploys even if the child is seated in the child restraint system. It is dan-
gerous if the SRS curtain shield airbag in flates, and the impact could cause death or
serious injury to the child.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat.
●Adjust the front passenger seat so that it does
not interfere with the child restraint system.
