The main purpose of an EDR is to record, in certain crash or near crash-like situations such as an airbag deployment or hitting a road obstacle, data that will assist in the understanding how a vehicle?s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as: ? How various systems in your vehicle were operating; ? Whether or not the driver and passenger safety belts were buckled/fastened; ? How far (if at all) the driver was depressing the accelerator and/or brake pedal; ? How fast the vehicle was traveling. This data can help provide a better understanding of the circumstances in which crashes and injuries occur.
