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.
