■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the extremely high speed deployment (inflation) by hot gases.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as thefront seats, 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 thresh-
old 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 cons iderably 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.
■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags w ill 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 vehiclecabin from a direction perpendicular to the vehicle orientation at an approximate
sp ee d o f 20 - 30 km/h [12 - 18 mph]).
●The SRS side and curtain shield airbags will de ploy 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, SRS side and curtain sh ield airbags may also deploy if a serious impact occurs to the underside of your vehi cle. Some examples are shown in the illustra-
tion.
■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 vehicle, deployment of the SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard sur-
face
●Falling into or jumpin g 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 co llision 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 rear collision, if it rolls over, or if it is involved in a low-speed side or low-speed frontal
collision.
●Collision from the side to the vehicle body other than the passenger compartment
●Collision from the side at an angle
●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 requ ire inspection and/or repair. Contact any
authorized Lexus dealer or repairer, or anot her duly qualified and equipped professional as soon as possible.
●Any of the SRS airbags have been inflated.
●The front of the vehicle is damaged ordeformed, or was involved in an accident that
was not severe enough to cause the SRS front airbags to inflate.
●A portion of a door or its surrounding area isdamaged or deformed, or the vehicle was
involved in an accident that was not severe enough to cause the SRS side and curtainshield airbags to inflate.
●The pad section of the steering wheel, dash-board near the front passenger airbag orlower portion of the instrument panel is
scratched, cracked, or otherwise damaged.

●The surface of the seats with the side airbag is scratched, cracked, or otherwise damaged.
●The portion of the front pillars, rear pillars orroof side rail garnishes (padding) containingthe curtain shield airbags inside is scratched,
cracked, or otherwise damaged.

“PASSENGER AIR BAG” indicator
The “ON” indicator light turns on when the airbag system is on (only when thepower switch is in ON mode).
Airbag manual on-off switch
Insert the mechanical key into the cylin-
der and rotate to the “OFF” position.
The “OFF” indicator light turns on (only when the power switch is in ON mode).
Airbag manual on-off system
This system deactivates the front passenger airbag and front passenger knee
airbag.
Only deactivate the airbags when using a child restraint system on the front
passenger seat.

■“PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that there is a malfunction in the sys- tem. Have the vehicle inspected by any author ized 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 switchedto “ON” or “OFF”.
WARNING
■When installing a child restraint system
For safety reasons, always install a child rest raint 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 manualon-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag deployment (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 inserious injury or even death.

When the sensors located at the back of the front bumper detect an impact with
a body, such as a pedestrian, which meet s or exceeds the threshold level while
the vehicle is being driven within the operational speed range, the system
becomes operational and raises the rear portion of the hood.

Lifters
Pop Up Hood
In the event of a frontal collision with a body, such as a pedestrian, the Pop Up
Hood system raises the rear portion of the hood to reduce the possibility of a
serious impact to the pedestrian’s he ad area by adding clearance to the
engine compartment.
