ECO ACURA RDX 2023 Owners Manual

Event Data RecordersThis 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 assist 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. Howeve r, other parties, such as law
enforcement, could co mbine 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 EDR is needed. In addition to the
vehicle manufacturer, other parties, such as law enforcement, that
have the special equipment, can re ad the information if they have
access to the vehicle or the EDR.
The data belongs to the vehicle ow ner and may not be accessed by
anyone else except as legally requ ired or with the permission of the
vehicle owner.
