■Front passenger occupant classification system precautions
Observe the following precautions regardin g front passenger occupant classification
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 th e 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 serious injury in the event of a collision.
●Do not apply a heavy load to the front pa ssenger seat or equipment (e.g. seatback
pocket).
●Do not put weight on the front passenger se at 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.

■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 pa ssenger 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 8 )
●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.

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-protector lock or the window lock switch to avoid
children opening the door while driving or operating the power window acci-
dentally. ( P. 110, 139)
●Do not let small children operate equi pment which may catch or pinch body
parts, such as the power window, 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.
WA R N I N G
Never leave children unattended in the vehicle, 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
(if equipped) or other features of the vehicle. In addition, heat build-up or extremely
cold temperatures inside the vehicle can be fatal to children.

Child restraint systems
●Choose a child restraint system that suits your vehicle and is appropriate to
the age and size of the child.
●For installation details, follow the instruct ions provided with the child restraint
system.
General installation instructions are provided in this manual. (P. 5 8 )
A child restraint system for a small child 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.
