cated computers that will record cer-
tain data, such as:
The recorded data varies according to
the vehicle grade level and options
with which it is equipped.
These computers do not record con-
versations or sounds, and only record
images outside of the vehicle in certain
situations.
 Engine speed / Electric motor
speed (traction motor speed)
 Accelerator status
 Brake status
 Vehicle speed
 Vehicles with PCS (Pre-Collision
System): Operation status of the
driving assist systems, such as the
ABS and pre-collision system
 Vehicles without PCS (Pre-Colli-
sion System): Operation status of
the driving assist systems, such as
the ABS and VSC
 Data usage
Lexus may use the data recorded in these
computers to diagnose malfunctions, con-
duct research and development, and
improve quality.
Lexus will not disclose the recorded data to
a third party except:
• With the consent of the vehicle owner or
with the consent of the lessee if the vehi-
cle is leased
• In response to an official request by the
police, a court of law or a government
agency
• For use by Lexus in a lawsuit

Event data recorder
This vehicle is equipped with an event
data recorder (EDR). The main pur-
pose of an EDR is to record, in certain
crash or near crash-like situations, such
as an airbag deployment or hitting a
road obstacle, data that will assist in
understanding how a vehicle's systems
performed. The EDR is designed to
record data related to vehicle dynam-
ics and safety systems for a short
period of time, typically 30 seconds or
less. However, data may not be
recorded depending on the severity
and type of a crash.
The EDR in this vehicle is designed to
record such data as:
 How various systems in your vehicle
were operating;
 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
understanding of the circumstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by your
vehicle only if a non-trivial crash situa-
tion occurs; no data are recorded by
