5-1. Essential information
Event data recorder
In a crash or a near car crash eventThe SRS airbag sensor assembly cont ains the EDR. In a crash or a near
car crash event, this devic e may record some or all of the following infor-
mation:
● Engine speed
● Whether the brake pedal was applied or not
● Vehicle speed
● To what extent the accelerator pedal was depressed
● Position of the 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
If your vehicles is equipped with a vehicle stability control (VSC) system
The VSC Electronic Control Unit (ECU) may contain another EDR. In
case the VSC or Brake Assist system is activated, or the lateral accelera-
tion is beyond a certain valve, this device may record some or all of the
following information:
● Behavior of the vehicle
● Steering wheel angle
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 usef ul for troubleshooting, there is an event data
recorder (EDR) that records data in a crash or a near car crash event.

5-1. Essential information
●Vehicle speed
● To what extent the accelerator pedal was depressed
● To what extent the brake pedal was applied
● To what extent the ECU controlled the condition of the 4 wheels
● Vehicle stability control system diagnostic data
The information abov e is intended to be used for the purpose of improv-
ing vehicle safety performance. Unlike general da ta recorders, the EDR
does not record sound data such as conversation between passengers.
Disclosure of the data
Lexus will not disclose the data re corded in an EDR to a third party
except when:
● An agreement from the vehicle's ow ner (or the leasing company for a
leased vehicle) is obtained
● Officially requested by the police or other authorities
● Used as a defense for Lexus in a law suit
● Ordered by a court law
However, if necessary Lexus will:
● Use the data for research on Le xus vehicle safety performance
● Disclose the data to a third party for research purposes without dis-
closing details of the vehicle owner, and only when it is deemed neces-
sary
● Disclose summarized data cleared of vehicle identification information
to a non-Lexus organization for research purposes
