For example, yourvehicle uses computer modules to monitor and controlengine and transmission performance, to monitor theconditions for airbag deployment and deploy airbags ina crash, and, if so equipped, to provide antilock brakingto help the driver control the vehicle. These modulesmay store data to help your dealer technician serviceyour vehicle. Some modules may also store data abouthow you operate the vehicle, such as rate of fuelconsumption or average speed. These modules mayalso retain the owner’s personal preferences, such asradio pre-sets, seat positions, and temperature settings.Event Data RecordersThis vehicle has an Event Data Recorder (EDR).The main purpose of an EDR is to record, in certaincrash or near crash-like situations, such as an airbagdeployment or hitting a road obstacle, data that willassist in understanding how a vehicle's systemsperformed. The EDR is designed to record data relatedto vehicle dynamics and safety systems for a shortperiod of time, typically 30 seconds or less.The EDR in this vehicle is designed to recordsuch data as:. How various systems in your vehicle wereoperating. Whether or not the driver and passenger safetybelts were buckled/fastened. How far, if at all, the driver was pressing theaccelerator and/or brake pedal. How fast the vehicle was travelingThis data can help provide a better understanding of thecircumstances in which crashes and injuries occur.Important: EDR data is recorded by your vehicle only ifa non-trivial crash situation occurs; no data is recordedby the EDR under normal driving conditions and nopersonal data (e.g., name, gender, age, and crashlocation) is recorded. However, other parties, such aslaw enforcement, could combine the EDR data with thetype of personally identifying data routinely acquiredduring a crash investigation.To read data recorded by an EDR, special equipment isrequired, and access to the vehicle or the EDR isneeded. In addition to the vehicle manufacturer, otherparties, such as law enforcement, that have the specialequipment, can read the information if they have accessto the vehicle or the EDR.8-19
