34 INTRODUCTION
EVENT DATA RECORDING DEVICES
Your Volvo vehicle is equipped with a device generally referred to as an "event data
recorder" or "EDR." Please note that while the term "event data recorder" is typically used
throughout the motor vehicle industry, not every EDR is the same; i.e., they do not all record
the same data elements. The EDR on your Volvo vehicle records vehicle speed, engine
rpm, time and date, plus a variety of pedal and switch positions, both before and after an
"event." Sudden vehicle deceleration or the occurrence of certain other vehicle operational
characteristics will define (trigger) an "event.”
If you have a question about your EDR, please contact your Volvo dealer or regional
service office.
