General notes
In general, this information documents the state
of a component part, a module, a system or the
surroundings such as:

R
its individual components (e.g. number of

In addition to providing the actual control unit
function, this data assists the manufacturer in
detecting and rectifying malfunctions and opti‐
mizing vehicle functions. The majority of this
data is temporary and is only processed in the
vehicle itself. Only a small portion of the data is
stored in the event or malfunction memory.
When your vehicle is serviced, technical data
from the vehicle can be read out by service net‐
work employees (e.g. workshops, manufactur‐
ers) or third parties (e.g. breakdown services).
Services include repair services, maintenance
processes, warranty cases and quality assurance
measures, for example. The read out is per‐
formed via the legally prescribed port for the
diagnostics connection in the vehicle. The
respective service network locations or third
parties collect, process and use the data. They
document technical statuses of the vehicle,
assist in finding malfunctions and improving
quality and are transmitted to the manufacturer,
if necessary. Furthermore, the manufacturer is
subject to product liability. For this, the manu‐
facturer requires technical data from vehicles.
Malfunction memories in the vehicle can be
reset by a service outlet as part of repair or
maintenance work.
Depending on the selected equipment, you can
import your own data into vehicle convenience
and infotainment functions.
This includes, for example:
multimedia data, such as music, films or pho‐
R
tos for playback in an integrated multimedia
system
address book data for use in connection with
R
an integrated hands-free system or an inte‐
grated navigation system
entered navigation destinations
R
data about the use of Internet services
R
This data can be saved locally in the vehicle or it
is located on a device which you have connected
to the vehicle (e.g. a smartphone, USB flash
drive or MP3 player). If this data is stored in the
vehicle, you can delete it at any time. This data
can only be transmitted to third parties upon
your request with particular regard to the scope
of use of online services according to your selec‐
ted settings.
You can store or change convenience settings/
individualizations in the vehicle at any time.
