IMPORTANT INFORMATION ABOUT YOUR LEXUS

Event data recorder
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 a system to record data
in a crash or a near car crash event. This is called an Event
Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In a
crash or a near car 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 transmission selector lever
Whether the driver and front passenger wore the seat belts
or not
Driver’s seat position
Front passenger’s occupant classification
SRS airbag deployment data
SRS airbag system diagnostic data
If your vehicle is equipped with a vehicle stability control (VSC)
system, its Electronic Control Unit (ECU) may contain another
EDR. There are a variety of driving situations which include
activating the VSC under which the VSC EDR will record
certain information. The VSC EDR may record some or all of
the following information:
Behavior of the vehicle
Steering wheel angle
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 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.
