*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 is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt
*4: When a larger child who has outgrown a child restraint system sits in the front pas-
senger seat, the system may recognize hi m/her as an adult depending on his/her
physique or posture.
*5: Never install a rear-facing child restraint system on the front passenger seat. A for-
ward-facing child restraint sy stem should only be installed on the front passenger
seat when it is unavoidable. ( P. 56)

WARNING
■Front passenger occupant classification system precautions
Observe the following precau tions 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 the rear seat. This
may cause the “AIR BAG OFF” indicator ligh t to be illuminated, which indicates that
the SRS airbags for the front passenger will no t activate in the event of a severe acci-
dent. If the seatback touches the rear seat, return the seatback to a position where it
does not touch the rear seat. Keep the fron t passenger seatback as upright as possi-
ble when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness 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 remain s 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 indica te a malfunction of the front passenger
occupant classification system. In this cas e, contact your Lexus dealer immediately.
●Child restraint systems installed on the second 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.

Safety information for children
●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. ( P. 124, 171)
●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.
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 other features of the vehi cle. In addition, heat build-up or extremely cold tempera-
tures inside the vehicle can be fatal to children.

Child restraint systems
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 su its your vehicle and is appropriate to
the age and size of the child.
●For installation details, follow the instru ctions provided with the child restraint
system.
General installation instructions are provided in this manual. ( P. 61)
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.
