To minimize the risk of fuel leakage when the engine stalls or when an air-
bag inflates upon collision, the fuel pump shut off system stops the supply of
fuel to the engine.

5-1. Essential information
Event data recorder
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 informa-
tion:
lEngine speed
lWhether the brake pedal was applied or not
lVehicle speed
lTo what extent the accelerator pedal was depressed
lPosition of the transmission shift lever
lWhether the driver and front passenger wore seat belts or not
lDriver's seat position
lSRS airbag deployment data
lSRS airbag system diagnostic data
lFront passenger’s occupant classification
The information above is intended to be used for the purpose of improv-
ing vehicle safety performance. Unlike general data recorders, the EDR
does not record sound data such as conversation between passengers.
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.

534
5-1. Essential information
Disclosure of the data
Lexus will not disclose the data recorded in an EDR to a third party
except when:
lAn agreement from the vehicle's owner (or the leasing company for a
leased vehicle) is obtained
lOfficially requested to by the police or other authorities
lNecessary, for use as a defense for Lexus in a law suit
lOrdered to by a court of law
However, if necessary Lexus will:
lUse the data for research on Lexus vehicle safety performance
lDisclose the data to a third party for research purposes without dis-
closing details of the vehicle owner, and that only when deemed neces-
sary
lDisclose summarized data cleared of vehicle identification information
to a non-Lexus organization for research purposes
