12-18 Customer InformationVehicle DataRecording andPrivacyYour GM vehicle has a number ofsophisticated computers that recordinformation about the vehicle’sperformance and how it is driven.For example, your vehicle usescomputer modules to monitor andcontrol engine and transmissionperformance, to monitor theconditions for airbag deploymentand deploy airbags in a crash and,if so equipped, to provide antilockbraking to help the driver control thevehicle. These modules may storedata to help your dealer/retailertechnician service your vehicle.Some modules may also store dataabout how you operate the vehicle,such as rate of fuel consumption oraverage speed. These modules mayalso retain the owner’s personalpreferences, such as radio pre-sets,seat positions, and temperaturesettings.Event Data RecordersThis vehicle has an Event DataRecorder (EDR). The main purposeof an EDR is to record, in certaincrash or near crash-like situations,such as an airbag deployment orhitting a road obstacle, data that willassist in understanding how avehicle's systems performed. TheEDR is designed to record datarelated to vehicle dynamics andsafety systems for a short period oftime, typically 30 seconds or less.The EDR in this vehicle is designedto record 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 waspressing the accelerator and/orbrake pedal. How fast the vehicle wastravelingThis data can help provide a betterunderstanding of the circumstancesin which crashes and injuries occur.Important: EDR data is recordedby your vehicle only if a non-trivialcrash situation occurs; no data isrecorded by the EDR under normaldriving conditions and no personaldata (e.g., name, gender, age, andcrash location) is recorded.However, other parties, such as lawenforcement, could combine theEDR data with the type ofpersonally identifying data routinelyacquired during a crashinvestigation.To read data recorded by an EDR,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.
