324 Customer Information
Vehicle Data
Recording and
Privacy
The vehicle has a number ofcomputers that record informationabout the vehicle’sperformanceandhow it is driven. For example, thevehicle uses computer modules tomonitor and control engine andtransmission performance, tomonitor the conditions for airbagdeployment and deploy them in acrash, and, if equipped, to provideantilock braking to help the drivercontrol the vehicle. These modulesmay store data to help the dealertechnician service the vehicle.Some modules may also store dataabout how the vehicle is operated,such as rate of fuel consumption oraverage speed. These modules mayretain personal preferences, such asradio presets, seat positions, andtemperature settings.
Event Data Recorders
This vehicle is equipped with anevent data recorder (EDR). Themain purpose of an EDR is torecord, in certain crash or nearcrash-like situations, such as an airbag deployment or hitting a roadobstacle, data that will assist inunderstanding how a vehicle’ssystems performed. The EDR isdesigned to record data related tovehicle dynamics and safetysystems for a short period of time,typically 30 seconds or less. TheEDR in this vehicle is designed torecord such data as:
.How various systems in yourvehicle were operating;
.Whether or not the driver andpassenger safety belts werebuckled/fastened;
.How far (if at all) the driver wasdepressing the accelerator and/or brake pedal; and,
.How fast the vehicle wastraveling.
These data can help provide abetter understanding of thecircumstances in which crashes andinjuries occur.
Note
EDR data are recorded by yourvehicle only if a non-trivial crashsituation occurs; no data arerecorded by the EDR under normaldriving conditions and no personaldata (e.g., name, gender, age, andcrash location) are recorded.However, other parties, such as lawenforcement, could combine theEDR data with the type ofpersonally identifying data routinelyacquired during a crashinvestigation.
To r e a d d a t a r e c o r d e d b y a n E D R ,special equipment is required, andaccess to the vehicle or the EDR isneeded. In addition to the vehiclemanufacturer, other parties, such aslaw enforcement, that have thespecial equipment, can read theinformation if they have access tothe vehicle or the EDR.
