■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 the
front 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.
●Vehicles with ERA-GLONASS: If the SRS airbags deploy, the system is designed tosend an emergency call* to the Public Safety Answering Point (PSAP), 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 asce rtain the level of emergency and assistance required. If the occupants are unable to communicate, the agent automatically treats
the call as an emergency and helps to dispatch the necessary emergency services.
( P. 496)
*: In some cases, the call cannot be made. (P. 498)
■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 wa ll that does not move or deform).
However, this threshold veloci ty 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 possible that only the seat belt pretensioners will
activate.
■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 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 perpendicular to th e vehicle orientation at an approximate
speed of 20 - 30 km/h [12 - 18 mph]).
●The SRS curtain shield airbags will 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.
■Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags do not gene rally 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 forwar d 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 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 air-
bags)
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 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 front
●Collision from the rear
●Vehicle rollover
●Collision from the rear
●Vehicle rollover

■When to contact any authorized Lexus retailer or Lexus authorized repairer, or any
reliable repairer
In the following cases, the vehicle will require inspection and/or repair. Contact any
authorized Lexus retailer or Lexus authorized re pairer, or any reliable repairer 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 front
airbags to inflate.
●A portion of a door or its surrounding area is damaged or deformed, or the vehicle was
involved in an acciden t that was not severe
enough to cause the SRS side and curtain shield airbags to inflate.
●The pad section of the steering wheel, dash-
board near the front passenger airbag or
lower 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 or
roof side rail garnishes (padding) containing
the curtain shield airbags inside is scratched, cracked, or otherwise damaged.

WARNING
■When installing a child restraint system
For safety reasons, always inst all 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 deployment (inflation) may cause seriou s 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.

When the sensors located at the back of the front bumper detect an impact with
a body, such as a pedestrian, which meets 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.

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.

The Pop Up Hood will operate when the vehicle detects an impact such as the
following:
●The front bumper detects a frontal impact equivalent to or greater than that of
a pedestrian while the vehicle being driv en within the operational speed range
of approximately 25 to 55 km/h (16 to 34 mph). (The system is operated by
an impact of threshold level or greater, even in the case of a minor collision
that may not leave a trace on the fron t bumper. Also, depending on the impact
conditions or vehicle speed , the system may be operated by a collision with a
light or small object or a small animal.)
●In other situations the system may oper ate when an impact is applied to the
lower part of the vehicle or front bumper, such as the following:
• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding object or
falling object
Pop Up Hood operational conditions
WARNING
■When the Pop Up Hood is operated
●Do not pull the hood lock release lever. Doing so after the Pop Up Hood has oper-
ated will further raise the h ood and may cause an injury. Do not drive with the hood raised, as doin g so may block the driver’s vision, possibly
causing an accident.
Do not forcibly push down the hood. As the popped up hood cannot be lowered by hand, doing so may deform th e hood or cause an injury.
If the Pop Up Hood has operated, have the vehicle inspected by any authorized
Lexus retailer or Lexus author ized repairer, or any reliable repairer. If the Pop Up Hood has operated, stop the vehicle in a sa fe place and contact any authorized Lexus
retailer or Lexus authorized repa irer, or any reliable repairer.
●Do not touch the lifters immediately after the Pop Up Hood has operated, as the lift- ers may be hot and burn you.
