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: D Engine speed D Whether the brake pedal was applied or not D Vehicle speed D To what extent the accelerator pedal was depressed D Position of the transmission selector lever D Whether the driver and front passenger wore the seat belts or not D Driver's seat position D Front passenger's occupant classification D SRS airbag deployment data D 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: D Behavior of the vehicle D Steering wheel angle D Vehicle speed D To what extent the accelerator pedal was depressed D To what extent the brake pedal was applied D To what extent the ECU controlled the condition of the 4 wheels D 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. iii
