Your vehicle has computers that monitor and control certain aspects of your vehicle. These computers assist in driving and maintaining optimal vehicle performance.

Besides storing data useful for troubleshooting, there is an event data recorder (EDR) that records data in a crash or near crash event.

In a crash or a near crash event

The SRS airbag sensor assembly contains the EDR. In a crash or near crash event, this device may record some or all of the following information: Engine speed.

Whether the brake pedal was applied or not.

Vehicle speed.

To what extent the accelerator pedal was depressed.

Position of the hybrid transmission shift lever.

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.

Disclosure of the 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 leasing company for a leased vehicle) is obtained.

Officially requested to by the police or other authorities.

Necessary, for use as a defense for Lexus in a law suit.

Ordered to by a court of law.

However, if necessary Lexus will: Use the data for research on Lexus vehicle safety performance.

Disclose the data to a third party for research purposes without disclosing details of the vehicle owner, and that only when deemed necessary.

Disclose summarized data cleared of vehicle identification information to a non-Lexus organization for research purposes.
