■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 seats, the glove box, parts of the front and rear pillars, and roof side rails may be
hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set
threshold level (the level of force corresponding to an approximately 20 - 30 km/h
[12 - 18 mph] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher in the following situa-
tions:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which canmove 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 possible that only the seat belt pretension-
ers will activate.
■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags will deploy in the event of an impact that
exceeds the set threshold level (the level of force corresponding to the impact
force produced by an approximately 1500 kg [3300 lb.] vehicle colliding with the
vehicle cabin from a direction perpendi cular to the vehicle orientation at an
approximate speed of 20 - 30 km/h [12 - 18 mph]).
●The SRS curtain shield airbags may also deploy in the event of a severe frontal colli-
sion.

■Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
■Types of collisions that may not depl oy 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 vehi-
cle, deployment of the SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling
●Collision from the side
●Collision from the rear
●Vehicle rollover

■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 and curtain shield 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.
●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

■When to contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional
In the following cases, the vehicle will require inspection and/or repair. Contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional as soon as possible.
●Any of the SRS airbags have been inflated.
●The front of the vehicle is damaged or
deformed, or was involved in an accident
that was not severe enough to cause the
SRS airbags to inflate.
●A portion of a door is damaged or
deformed, or the vehicle was involved in an
accident that was not severe enough to
cause the SRS side and curtain shield air-
bags to inflate.
●The pad section of the steering wheel, dash-
board near the front passenger airbag,
lower portion of the instrument panel or
door of the glove box is scratched, cracked,
or otherwise damaged.

system. Have the vehicle inspected by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●Neither “ON” nor “OFF” comes on.
●The indicator light does not change when the airbag manual on-off switch is
switched to “ON” or “OFF”.

CAUTION
■When installing a child restraint system
For safety reasons, always install a child restraint system in a rear seat. In the event
that the rear seat cannot be used, the front seat can be used as long as the airbag
manual on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag deploy-
ment (inflation) may cause serious injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on.
If it is left off, the airbag may not deploy in the event of an accident, which may
result in serious injury or even death.

Safety information for children
●It is recommended that children sit in the rear seats to avoid accidental
contact 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 accidentally. ( →P. 172, 204)
●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 wh en children are in the vehicle.
Use a child restraint system appropri ate 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 shift 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 addition, heat build-up or extremely
cold temperatures 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 suits your vehicle and is appropri-
ate to the age and size of the child.
●For installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual. (→P. 7 0 )
●If child restraint system regulations exist in the country where you
reside, please contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional for the child restraint
system installation.
●Lexus recommends that you use a child restraint system which con-
forms to the regulation ECE No.44.
Lexus strongly urges the use of child restraint systems.
