■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-
old level (the level of force corresponding to an approximately 12 - 18 mph [20 - 30
km/h] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move
or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle “underrides”, or goes under, the bed of a truck
●Depending on the type of collision, it is possib le that only the seat belt pretensioners will
activate.
●The SRS front airbags for the front passenger will not activate if there is no passenger
sitting in the front passenger seat. However, the SRS front airbags for the front passen-
ger may deploy if luggage is put in the seat, even if the se at is unoccupied. (P. 4 7 )
■SRS airbag deployment conditions (S RS side and curtain shield airbags)
●The SRS side and curtain shield airbags will deploy in the event of an impact that
exceeds the set threshol d level (the level of force corresponding to the impact force
produced by an approximately 3300 lb. [1500 kg] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate
speed of 12 - 18 mph [20 - 30 km/h]).
●The SRS curtain shield airbags may also deploy in the event of a severe frontal collision.
■Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags and SRS curtain shield airbags may also deploy if a serious impact
occurs to the underside of your vehicle. Some examples are shown in the illustration.
●Hitting a curb, edge of pavement or hard sur-
face
●Falling into or jumping over a deep hole
●Landing hard or falling

■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 4 )
*6: In case the indicator light is not illuminated, consult this manual on how to install the
child restraint system properly. ( P. 5 8 )

CAUTION
■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 light 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 SR S airbags for the front passenger may 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.

CAUTION
■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 light to be illuminated, which indicates that
the SRS airbags for the front passenger will not deploy 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 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.
●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.

●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.
●Do not let small children operate equi pment which may catch or pinch body
parts, such as the power window, hood, trunk, seats etc.
Safety information for 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.
CAUTION
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
or other features of the vehicle. In additi on, heat build-up or extremely cold tempera-
tures inside the vehicle can be fatal to children.

541-1. For safe use
IS350/250_U (OM53C50U)
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 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 )
Child restraint systems
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.
Points to remember

For safety and security
IS350/250_U (OM53C50U)
Child restraint systems are classified into the following 3 types according to the
age and size of the child:
■Selecting an appropriate child restraint system
●Use a child restraint system appropriate for the child until the child becomes large
enough to properly wear the vehicle’s seat belt.
●If the child is too large for a child restraint system, sit the ch ild on a rear seat and use the
vehicle’s seat belt. ( P. 3 0 )
