5-1. Essential information
Event data recorder
In a crash or a near car crash eventThe SRS airbag sensor assembly c ontains the EDR. In a crash or a
near car crash event, this device may record some or all of the follow-
ing information:
● Gasoline 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
● Front passenger’s occupant classification
● 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.
Your vehicle has computers that monitor and control certain aspects
of your vehicle. These computers assi st in driving and maintaining
optimal vehicle performance.
Besides storing data useful for tr oubleshooting, there is an event
data recorder (EDR) that records data in a crash or a near car
crash event.

5-1. Essential information
Disclosure of the data
Toyota will not disclose the data recorded 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 Toyota in a law suit
● Ordered by a court law
However, if necessary Toyota will:
● Use the data for research on Toyota vehicle safety performance
● Disclose the data to a third party for research purposes without dis-
closing details of the vehicle ow ner, and only when it is deemed
necessary
● Disclose summarized data cleared of vehicle identification informa-
tion to a non-Toyota organization for research purposes
