SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain types of
severe impacts that may cause signific ant injury to the occupants. They
work together with the seat belts to he lp reduce the risk of death or serious
injury.
SRS front airbags
SRS driver airbag/front passenger airbag 
Can help protect the head and ches t of the driver and front passen-
ger from impact with interior components
SRS knee airbags 
Can help provide driver and front passenger protection

Can help protect the torso of the front seat occupants.
Rear SRS side airbags (if equipped) 
Can help protect the torso of the outer second seat occupants.
SRS curtain shield airbags 
Can help protect primarily the he ad of occupants in the outer seats

1-7. Safety information
GX460_U.S.A. (OM60E69U)Your vehicle is equipped with AD
VANCED AIRBAGS designed based
on the US motor vehicle safety st andards (FMVSS208). The airbag sys-
tem controls airbag deployment power for the driver and front passen-
ger. The driver airbag system consists of the driver’s seat belt buckle
switch etc. The front passenger’s airbag system consists of the front pas-
senger occupant classification sensor etc.
The main SRS airbag system componen ts are shown above. The SRS air-
bag system is controlled by the airb ag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and a main sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemica l reaction in the inflators quickly
fills the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants.

■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, center and rear pillars and roof side rail,
may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For Safety Connect subscriber s, 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 location (without needing to
push the “SOS” button) 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 agent automatically treats the call as an emer-
gency and helps to dispatch the necessary emergency services. ( P. 5 8 0 )

■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbag will deploy in the event of an impact that exceeds the set
threshold level (the level of force corresponding to a 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 if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed thresh old level, the SRS front airbags and the
seat belt pretensioners ma y not activate together.
●The SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the SRS front passenger airbag may
deploy if luggage is put in the seat, or the seat belt is fastened, even if the seat is
unoccupied. ( P. 1 4 0 )
■SRS airbag deployment conditions (SRS side airbags 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 a 3307 lb. [1500 kg] vehicle colliding with the vehicle cabin from a
direction perpendicular to the vehicle orie ntation at a speed of 12 - 18 mph [20 -
30 km/h]).

■Conditions under which the SRS airbags may deploy (inflate), other than a colli-
sion
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.
The SRS curtain shield airbags may also deploy under the situations shown in the
illustration.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling
●The angle of vehicle tip-up is marginal.
●The vehicle skids and hits a curb stone.

■Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags are generally not designed to 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 colli-
sion. But, whenever a collision of any type causes sufficient forward deceleration of
the vehicle, deployment of th e SRS front airbags may occur.
■Types of collisions that may not deploy the SRS airbags 
(SRS side airbags and curtain shield airbags)
The SRS side airbag and curtain shield ai rbag system 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.
●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

The SRS side airbags are not generally designed to 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 colli-
sion.
The SRS curtain shield airbags are not generally designed to inflate if the vehicle is
involved in a frontal or rear collision, if it pitches end over, or if it is involved in a low-
speed side collision.
●Collision from the front
●Collision from the rear
●Vehicle rollover
●Collision from the front
●Collision from the rear
●Pitches end over end

■When to contact your Lexus dealer
In the following cases, contact your Lexus dealer as soon as possible. Do not dis-
connect the battery cables before contacting your Lexus dealer.
●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 the doors is damaged or
deformed, or the vehicle was involved in an
accident that was not severe enough to
cause the SRS side airbags and curtain
shield airbags to inflate.
