■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating) SRS
airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as the
front seats, parts of the front, side and rear pillars and roof side rails, may be hot for sev-
eral minutes. The airbag itself may also be hot.
●The windshield may crack.
●For Safety Connect subscribers, if the SRS airbags deploy or in the event of a severe
rear-end collision, the system is designed to send an emergency call to the response
center, notifying them of the vehicle’s locat ion (without needing to push the “SOS” but-
ton) and an agent will attempt to speak with the occupants to ascertain the level of
emergency and assistance required. If the occupants are unable to communicate, the
argent automatically treats the call as an emergency and helps to dispatch the neces-
sary emergency services. ( →P. 4 2 8 )
CAUTION

Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer. The SRS airbags may malfunction or deploy (inflate)
accidentally, causing death or serious injury.
●Installation, removal, disassembl y and repair of the SRS airbags

panel, dashboard, seats, seat upholstery, fron t, side and rear pillars or roof side rails

■Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags do not generally inflate if the vehicle is involved in a side or rear
collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a
collision of any type causes sufficient forward deceleration of the vehicle, deployment of
the SRS front airbags may occur.
■Types of collisions that may not deploy the SRS airbags
(SRS side and curtain shield airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is subjected to a
collision from the side at certain angles, or a collision to the side of the vehicle body other
than the passenger compartment.
The SRS side airbags do not generally inflate if the vehicle is involved in a frontal or rear
collision, if it rolls over, or if it is involved in a low-speed side collision.
The SRS curtain shield airbags do not generally inflate if the vehicle is involved in a rear
collision, if it pitches end over end, or if it is involved in a low-speed side collision.
●Collision from the side
●Collision from the rear
●Vehicle rollover
●Collision from the side to the vehicle body
other than the passenger compartment
●Collision from the side at an angle
●Collision from the front
●Collision from the rear
●Vehicle rollover
●Collision from the rear
●Pitching end over end

■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 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 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.

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.
●Do not let small children operate equipment which may catch or pinch body
parts, such as the power window, hood, trunk, 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 we ar 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 shift 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.

For safety and security
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 fo r 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 sy stem, sit the child on a rear seat and use the
vehicle’s seat belt. ( →P. 2 8 )

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 windshield, or between
you and the vehicle’s interior.
●Lexus strongly urges the use of a proper ch ild 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 even if
the “AIR BAG OFF” indicator light is illuminated.
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 sys-
tem is installed on th e front passenger seat.
●A forward-facing child restraint system ma y be installed on the front passenger seat
only when it is unavoidable. A child restra int system that requires a top tether strap
should not be used in the front passenger seat since there is no top tether strap
anchor for the front passenger seat. Adjust the seatback as upright as possible and
always move the seat as far back as possible even if the “AIR BAG OFF” indicator
light is illuminated, because the front passen ger 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 inst alling 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 w ill not securely hold the child restraint sys-
tem, which could cause death or serious injury to the child or other passengers in the
event of a sudden stop, sudden swerve or accident.
●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, center an d rear pillars or roof side rails from which
the SRS side airbags or SRS curtain shield ai rbags deploy even if the child is seated in
the child restraint system. It is dangerous if the SRS side airbags and curtain shield air-
bags inflate, and the impact could cause death or serious injury to the child.
●Make sure you have complied with all insta llation 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, sudden swerve or accident.
