Customer Information
Collection and Processing of Data in the Vehicle
For more information on your legal
rights relating to Mazda (for example,
your right to the deletion and
correction of data), please refer to the
applicable Data Protection Policy on
the country-specific Mazda website,
where contact details are also
provided.
Data, which is exclusively stored locally
on the vehicle, may be viewed with
expert assistance, e.g., in a vehicle
workshop, in return for payment if
appropriate.
Legal requirements regarding the
disclosure of data
To the extent that legal regulations
exist, manufacturers are obliged to
release information stored by them, at
the request of public authorities, to the
extent required on a case-by-case
basis (e.g., when a criminal offence is
being investigated).
Public authorities are also permitted to
read the data from vehicles in specific
cases, within the scope of applicable
law. For example, in the event of an
accident, information can be read from
the air bag control unit to help clarify
the circumstances of the accident.
Operational data on the vehicle
Control units process data in order to
operate the vehicle.
These include, for example:
vehicle status information (e.g.,

speed, deceleration, lateral
acceleration, wheel speed, seatbelt
usage indicator),
8-6
environmental conditions (e.g.,

temperature, rain sensor, distance
sensor).
These data are generally volatile and
are not stored beyond the operating
time, and only processed on the
vehicle itself. Control units frequently
contain data storage media. These can
be used to document, either
temporarily or permanently,
information about the condition of the
vehicle, component stress,
maintenance requirements and
technical events and failures.
The following information may be
stored, depending on the technical
configuration:
operating conditions of system

components (e.g., fill levels, tyre
pressures and battery status),
malfunctions and defects in

important system components (e.g.,
lighting and brakes),
response of the system to

extraordinary driving situations (e.g.,
deployment of an air bag, activation
of stability control systems),
information on events in which the

vehicle is damaged,
for electric vehicles, the state of

charge of the high-voltage battery
and the vehicle's estimated range.
In particular cases (e.g., if the vehicle
has detected a malfunction), it may be
necessary to store data which would
normally be volatile.
