Event datarecorders
USA only:
Thisvehicle is equipped with anevent datarecorder (EDR). The main purpose of an EDR istorecord, in certain crash or near crash-like sit‐uations, such as an airbag deployment or hittingaroad obstacle, datathat will assist in under‐standing how avehicle's systems performed.The EDR is designedtorecord datarelatedto
vehicle dynamics and safety systemsfor a shortperiod of time, typically 30 seconds or less.
The EDR inthisvehicle is designedtorecordsuchdata as:
RHowvarious systems inyourvehiclewereoperating
RWhether or notthe driver and frontpassenger seat beltswerebuckled/fastened
RHowfar (if at all)the driverwas depressingthe accelerator and/or brake pedal and
RHowfastthevehiclewas traveling
This data can help provide a better understand‐ing ofthe circumstances in which accidents andinjuries occur. NOTE: EDR data isrecordedbyyourvehicle only if a non-trivial crash situationoccurs; no data isrecordedbythe EDR undernormal driving conditions and no personal data(e.g. name,gender,age and accident location) isrecorded. However,other parties, such as lawenforcement, could combine EDR data withthetype of personally identifying dataroutinelyacquired during a crash investigation.
