Event Data Recorders
This vehicle is equipped with an event data recorder (EDR).
The main purpose of an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deployment or hitting a
road obstacle, data that will assi st in 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; and,
• How fast the vehicle was traveling.

These data can help provide a better understanding of the
circumstances in which crashes and injuries occur. NOTE: EDR data
are recorded by your vehicle only if a non-trivial crash situation
occurs; no data are recorded by the EDR under normal driving
conditions and no personal data (e.g., name, gender, age, and
crash location) are recorded. Howe ver, other parties, such as law
enforcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a crash
investigation.
To read data recorded by an ED R, special equipment is required,
and access to the vehicle or the ED R is needed. In addition to the
vehicle manufacturer, other parties, such as law enforcement, that
have the special equipment, can r ead the information if they have
access to the vehicle or the EDR.
The data belongs to the vehicle owner and may not be accessed by
anyone else except as legally required or with the permission of the
vehicle owner.Service Diagnostic Recorders
This vehicle is equipped with serv ice-related devices that record
information about powertrain performance. The data can be used
to verify emissions law requirements and/or help technicians
diagnose and solve service problems. It may also be combined with
data from other sources for research purposes, but it remains
confidential. Some diagnostic and maintenance information is
uploaded to Honda upon vehicle start up.
California Perchlorate Contamination Prevention Act
