Electronic Brake Force
Distribution System Wa r n i n g If the electronic brake force di
stribution control unit determines that some compo‐
nents are operating incorrectly , the control unit may illuminate the brake system

Event Data Recorder (U.S.A. and Canada)
This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is
to record, in certain crash or ne ar 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 vehicl e dynamics and safety
systems for a short period of time, typically 30 seconds or les s. The EDR in this vehicle is
designed to record such data as:
How various systems in you r vehicle were operating;
Whether or not the driver and passenger safety belts were buckl ed/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 circu mstances in which crashes
and injuries occur.
NOTE:
EDR data are recorded by your vehicle only if a non-trivial cra sh or near crash-like situation
occurs; no data are recorded by the EDR under normal driving co nditions and no personal
data (e.g., name, gender, age, an d crash location) are recorded. However, other parties, such
as law enforcement, could combine the EDR data with the type of personally identifying
data routinely acquired du ring a crash investigation.
To read data recorded by an EDR, special equipment is required, and access to the vehicle or
the EDR is needed. In addition to the vehicle manufacturer, oth er parties, such as law
enforcement, that have the special equipment, can read the info rmation if they have access
to the vehicle or the EDR.

Mazda will not disclose any of the data recorded in an EDR to a third party unless:
A written agreement from the vehicle owner or the lessee is obtained
Officially requested by the police or other law enforcement authorities
Used as a defense for Mazda in a lawsuit, claim, or arbitration
Ordered by a judge or court
However, if necessary Mazda will:
Use the data for research on Mazda vehicle performance, includi ng safety.
Disclose the data or the summarized data to a third party for research purposes without
disclosing vehicle or owner identification information.
