Inaddition,yourvehicle provides comfortandentertainment functions, which are also madepossiblebyelectronic control units.
Electronic control units contain datamemorieswhichcantemporarily or permanentlystore
technical information aboutthevehicle's operat‐ingstate, component loads, maintenancerequirements andtechnicalevents or malfunc‐tions.
Ingeneral,this information documentsthestateof a component part, a module, a system orthesurroundings such as:
Roperatingstatus of system components (e.g.fill levels, batterystatus, tire pressure)
Rstatus messages concerningthevehicle orits individual components (e.g. number ofwheelrevolutions/speed, longitudinal accel‐eration, lateral acceleration, display offas‐tened seat belts)
Rmalfunctions orfaults in important systemcomponents (e.g. lights, brakes)
Rinformation onevents leadingtovehicledamage
Rsystemreactions in special driving situations(e.g. airbag deployment, intervention ofsta‐bility control systems)
Rambient conditions (e.g.temperature,rainsensor)
In additiontoprovidingthe actual control unitfunction,this data assiststhe manufacturer indetecting andrectifying malfunctions and opti‐mizingvehicle functions. The majority ofthisdata istemporary and is only processed inthevehicle itself. Only a small portion ofthe data isstored intheevent or malfunction memory.
Whenyourvehicle is serviced,technical datafromthevehicle can beread outbyservice net‐workemployees (e.g.workshops, manufactur‐ers) orthird parties (e.g. breakdown services).Services includerepair services, maintenanceprocesses,warranty claims andquality assur‐ance measures,forexample. Theread out is per‐formed viathe legally prescribed portforthediagnostics connection inthevehicle. Therespective service network locations orthirdparties collect, process and usethe data.

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
RHowfast thevehiclewas 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.
