Vehicle control and operation data recording
Your Lexus is equipped with sophisticated computers that record certain informa-
tion about your vehicle’s operation, such as:
•Engine speed
• Accelerator status
•Brake status
•Vehicle speed
• Shift position (except manual transmission)
The data recorded varies according to the grade level and options the vehicle is
equipped with. The computers do not record conversations, sound or pictures.
●Data usage
Lexus may use the data recorded in these computers to diagnose malfunctions,
conduct 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
vehicle is leased
• In response to an official request by the police, a court of law or a government
agency
• For research purposes where the data is not tied to a specific vehicle or vehicle owner

22
●Event data recorder
Your vehicle has computers that monitor and control certain aspects of your vehi-
cle. These computers assist in driving an d maintaining optimal vehicle performance.
Besides storing data useful for troublesh ooting, there is an event data recorder
(EDR) that records data in a crash or near crash event.
The SRS airbag sensor assembly contains the EDR. In a crash or near crash event,
this device may record the following information:
•Engine speed
• Whether the brake pedal was depressed or not
• Vehicle speed
• To what extent the accelerator pedal was depressed
• The transmission shift position
• Whether the driver and front passenger wore seat belts or not
• Driver’s seat position
• SRS airbag deployment data
• SRS airbag system diagnostic data
• Front passenger’s occupant classification
The information above is intended to be used for the purpose of improving vehicle
safety performance. Unlike general data recorders, the EDR does not record sound
data such as conversation between passengers.
