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.

Recording of Vehicle Data
This vehicle is equipped with a computer which records the following main vehicle data
related to vehicle controls, ope ration, and other driving conditions.

Recorded data
Vehicle conditions such as engine speed and vehicle speed
Driving operation conditions such as accelerator and brake peda ls, and information related
to the environmental circumstances while the vehicle is driven
Malfunction diagnosis i nformation from each on-vehicle computer
Information related to controls of other on-vehicle computers
NOTE
The recorded data may vary depending on the vehicle grade and optional equipment. Voice
and images are not recorded.

Data handling
Mazda and its subcontracting parties may obtain and use the rec orded data for vehicle
malfunction diagnosis, research and development, and quality im provement.
Mazda will not disclose or provide any of the obtained data to a third party unless:
An agreement from the vehicle owner (agreements from lessor and lessee for leased
vehicle) is obtained
Officially requested by the police or other law enforcement aut horities
For statistical processing by a research institution after processing the data so that
identification of the owner o r the vehicle is impossible

information about the tire brand and manufacturing plant, tire size, and date of manufacture.
Inflation Pressure: A measure of the amo unt of air in a tire.
kPa: Kilopascal, the metric unit for air pressure.
psi: Pounds per square inch, the English unit for air pressure.
B-pillar: The structural member at the side of the vehicle behind the fr ont door.
Original Equipment (OE): Describes components originally equipped on the vehicle.
Vehicle Load Limit: The maximum value of the combination weight of occupants and
cargo.
Bead Area of the Tire: Area of the tire next to the rim.
Sidewall Area of the Tire: Area between the bead area and the tread.
Tread Area of the Tire: Area on the perimeter of the tire that contacts the road when it's
mounted on the vehicle.

Seating capacity means the total allowable number of vehicle occupants. Seating capacity
is described on the tire label.

WA R N I N G
Do not tow a trailer with this vehicle:
Towing a trailer with this vehicle is dangerous because it has not been designed to tow a
trailer and doing so will affect the drive system which could result in vehicle damage.
This section will guide you in the proper loading of your vehicle, to keep your loaded
vehicle weight within its desi gn rating capability. Properly lo ading your vehicle will provide
maximum return of vehicle design performance. Before loading yo ur vehicle, familiarize
yourself with the following terms for determining your vehicle' s weight ratings, from the
vehicle's Safety Certification La bel and Tire and Load Information Label:
WA R N I N G
Overloaded Vehicle:
Overloading a vehicle is danger ous. The results of overloading can have serious consequences
in terms of passenger safety. Too much weight on a vehicle's suspension system can cause
spring or shock absorber failure, brake failure, handling or steering problems, irregular tire
wear, tire failure or other damage.
Overloading makes a vehicle harder to drive and control. It also increases the distance
required for stopping. In cases of serious overloading, brakes can fail completely, particularly
on steep grades. The load a tire will carry safely is a combination of the size of the tire, its load
range, and corresponding inflation pressure.
Never overload the vehicle and always observe th e vehicle's weight ratings from the vehicle's
Safety Certification and Tire and Load Information labels.
