This vehicle is equipped with an event data recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist in understanding how a
vehicle’s systems performed. The EDR is desi gned to record data related to vehicle
dynamics and safety systems for a short peri od of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as: • How various systems in your vehicle were operating;
• Whether or not the driver and passenge r safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better unde rstanding of the circumstances in which
crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a nontrivial crash situation
occurs; no data are recorded by the EDR under normal driving conditions and no
personal data (e.g., name, gender, age, and crash location) are recorded. However,
other parties, such as law enforcement, could combine the EDR data with the type of
personally identifying data routinely ac quired during a crash investigation.
To read data recorded by an EDR, special equipment is required, and access to the
vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties,
such as law enforcement, that have the special equipment, can read the information
if they have access to the vehicle or the EDR.
● Disclosure of the EDR data
Lexus will not disclose the data recorded in an EDR to a third party except when:
• An agreement from the vehicle’s owner (or the lessee for a leased vehicle) is obtained
• In response to an official request by the police, a court of law or a government agency
• For use by Lexus in a lawsuit
However, if necessary, Lexus may:
• Use the data for research on vehicle safety performance
• Disclose the data to a third party for re search purposes without disclosing infor-
mation about the specific vehicle or vehicle owner

■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 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 in the following situa-
tions:
• 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 po ssible that only the seat belt pretension-
ers will activate.
●The SRS front airbags for the front passenger will not activate if there is no passen-
ger sitting in the front passenger seat. Ho wever, the SRS front airbags for the front
passenger may deploy if luggage is put in the seat, even if the seat is unoccupied.
(  P. 4 9 )
■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 3300 lb. [1500 kg] vehicle colliding with the
vehicle cabin from a direction perpendicular to the vehicle orientation at an
approximate speed of 12 - 18 mph [20 - 30 km/h]).
●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.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling

■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 vehi-
cle, deployment of the SRS front airbags may occur.
■Types of collisions that may not deploy th e 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
●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
*: Depending on the conditions and type of
accident, the curtain shield airbags may
deploy (inflate) upon frontal impact.

Hybrid system precautions
Take care when handling the hybrid system, as it contains a high voltage
system (about 650 V at maximum) as well as parts that become
extremely hot when the hy brid system is operating. Obey the caution
labels attached to the vehicle.
