Nissan Leaf 2018-2025 (ZE1) Owner's Manual : Event Data Recorders (EDR)
Your Nissan Leaf is engineered with a sophisticated Event Data Recorder (EDR). The primary objective of this system is to capture and store technical data during specific crash or near-crash scenarios—such as instances where an airbag deploys or the vehicle sustains a significant impact with an obstacle. This information is invaluable for reconstructive analysis, helping engineers and investigators understand precisely how the various safety and mechanical systems of your Nissan Leaf performed under duress. The EDR is designed to record transient data related to vehicle dynamics and safety system status for a brief, critical window of time, typically lasting 30 seconds or less.
In the event of a qualifying incident, the EDR installed in your Nissan Leaf is programmed to log specific parameters, including:
- The operational status of various primary vehicle systems;
- Whether the driver and front passenger safety belts were securely fastened at the time of the event;
- The degree of input applied to the accelerator and/or brake pedals by the driver;
- The precise ground speed of the vehicle; and,
- Note that no audio or voice recordings are captured by this system.
These data points provide essential insights into the complex circumstances surrounding collisions and potential injuries. Importantly, the EDR in your Nissan Leaf only records data if a non-trivial crash event occurs; no information is gathered during routine, day-to-day driving, and the system does not record any personal identifiable information, such as your name, gender, age, or the specific GPS location of the incident. However, it is important to acknowledge that third parties, such as law enforcement agencies, may correlate this technical EDR data with other personally identifying information acquired through their standard investigative procedures.
Retrieving information from an EDR requires specialized diagnostic equipment and direct physical access to the vehicle or the EDR module itself. Beyond the manufacturer and authorized NISSAN certified LEAF dealers, other parties—including law enforcement officials—may be able to extract this data if they have legal access to the vehicle and possess the necessary proprietary equipment.
Access to EDR data is strictly regulated and will only occur with the explicit consent of the vehicle owner or lessee, or as otherwise mandated or permitted by applicable law.
Additional data recording (on vehicles equipped with optional ProPILOT Assist)
If your Nissan Leaf is configured with the optional ProPILOT Assist suite, the vehicle is further equipped with a supplemental data recording function designed to support the advanced driver-assistance systems.
This supplementary function captures detailed technical information, including:
- Operational status of driver inputs regarding acceleration, braking, and steering maneuvers;
- The system’s detection status concerning vehicles ahead and lane marker visibility;
- Core vehicle telemetry, such as the distance maintained to a leading vehicle and the car's lateral position within the lane;
- Detailed information regarding the active operation of ProPILOT Assist and integrated crash avoidance features;
- Diagnostic data related to potential ProPILOT Assist system malfunctions; and,
- External visual data captured by the multi-sensing front camera (this feature is activated exclusively when the SRS airbag system or the Automatic Emergency Braking (AEB) with Pedestrian Detection system is triggered).
Please be assured that the ProPILOT Assist system in your Nissan Leaf does not record any conversations, ambient sounds, or images of the vehicle's interior.
Retrieving this technical vehicle data requires specialized diagnostic equipment and direct physical access to your Nissan Leaf or the internal recording unit. Please be assured that such data will only be accessed with the explicit consent of the vehicle owner or lessee, or under circumstances specifically required or permitted by governing laws.
In the event that this data is downloaded, NISSAN may utilize the recorded information to further research and improve the safety performance and design standards of our future vehicles.
NISSAN maintains a strict policy regarding data privacy and will not disclose or provide this recorded information to any third party, except in the following scenarios:
- With the documented consent of the vehicle owner or the lessee;
- In response to an official, legally enforceable request from law enforcement authorities, a court order, or an authorized governmental agency;
- For use by NISSAN as part of the necessary defense during legal litigation;
- For generalized research purposes, provided that the data has been anonymized or modified so that it is no longer linked to a specific Nissan Leaf or individual owner.
If you have any questions regarding the specific types of data that NISSAN may collect, we encourage you to review our comprehensive Privacy Policy at https://www.nissanusa.com.
