Event Data Recorder - Lexus LFA Owner's Manual

5-1. Essential information

Event data recorder

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
airbag deployment or hitting a road obstacle, data that will assist in under-
standing how a vehicle's systems performed. The EDR is designed to record
data related to vehicle dynamics and safety systems for a short period 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 passenger safety belts (seat 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 understanding of the circumstances
in which crashes and injuries occur.
NOTE:
EDR data are recorded by your vehicle only if a non-trivial crash situation
occurs; no data are recorded by the EDR under normal driving condi-
tions 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 rou-
tinely acquired during a crash investigation.
