nance requirements as well as technical events
and malfunctions.
This information generally documents the con-
dition of a component, a module, a system or the
surroundings, such as:
R
Operating states of system components (e.g.
fill levels, battery status, tire pressure)
R
Status messages concerning the vehicle or its
individual components (e.g. wheel rpm/
speed, deceleration, lateral acceleration, indi-
cation of whether seat belts are fastened)
R
Malfunctions and defects in important system
components (e.g. lights, brakes)
R
Information about events leading to vehicle
damage
R
System responses in special driving situa-
tions (e.g. air bag deployment, intervention of
stability control systems)
R
Ambient conditions (e.g. temperature, rain
sensor)
In addition to performing the actual control unit
function, this data is used by manufacturers to
detect and rectify malfunctions and to optimize
vehicle functions. Most of this data is volatile
and processed only in the vehicle itself. Only a
small part of the data is stored in event or mal-
function memories.
When you use services, the technical data from
the vehicle can be read out by service network
employees (e.g. workshops, manufacturers) or
third parties (e.g. breakdown services). Services
can include repair services, maintenance pro-
cesses, warranty cases and quality assurance
measures. The data are read out via the con-
nection for the diagnostics connection in the
vehicle, which is required by law. The relevant
offices in the service network or third parties
collect, process and use the data. This data
documents the vehicle's technical states, is
used to help in finding malfunctions and improv-
ing quality and is sent to the manufacturer
where necessary. In addition, the manufacturer
is subject to product liability. The manufacturer
needs technical data from vehicles for this pur-
pose.
Malfunction memories in the vehicle can be
reset by a service center during repair or service
work.
You can incorporate data into the vehicle's com-
fort and infotainment functions yourself as part
of the selected equipment.
These include, for example:
R
Multimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
R
Address book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
R
Navigation destinations that have been
entered
R
Data about using Internet services
This data can be saved locally in the vehicle or
located on a device that you have connected to
the vehicle (e.g. smartphone, USB memory stick
or MP3 player). If this data is saved in the vehi-
cle, you can delete it at any time. This data is
sent to third parties only at your request, par-
ticularly when you use online services in accord-
ance with the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the equipment in question, these
can include:
R
Seat and steering wheel position settings
R
Suspension and climate control settings
R
Custom settings such as interior lighting
If your vehicle is equipped appropriately, you
can connect your smartphone or another mobile
end device to the vehicle. You can control this by
means of the control elements integrated in the
vehicle. The smartphone's picture and sound
can be output via the multimedia system. Spe-
cific items of information are also sent to your
smartphone.
Depending on the type of integration, this can
include:
R
General vehicle information
R
Position data
This allows the use of selected smartphone
apps, such as navigation or music player apps.
There is no additional interaction between the
smartphone and the vehicle, particularly active
access to vehicle data. The type of additional
data processing is determined by the provider of
the app being used. Whether you can configure
settings for it and, if so, which ones, depends on
the app and your smartphone's operating sys-
tem.
