This data can be saved locally in the vehicle or
is located on a device that you have connected
to the vehicle (e.g. smartphone, USB flash
drive or MP3 player). If this data is saved in
the vehicle, you can delete it at any time.
Transfer of this data to third parties is only
possible at your request, predominantly while
using online services and in accordance with
the settings you have selected.
You can save convenience settings/customi-
zations in the vehicle and change them at any
time.
Depending on the piece of equipment in ques-
tion, these can include:
R settings for the seat and steering wheel
positions
R suspension and air-conditioning settings
R customizations 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
operate this device using the integrated con-
trols in the vehicle. This allows images and
sound from the smartphone to be output
through the multimedia system. Simultane-
ously, certain information is transferred to
your smartphone.
Depending on the type of integration, this can
include:
R general vehicle status
R position data
This allows the use of selected smartphone
apps, such as navigation or music player apps.
No further interaction between smartphone
and vehicle takes place and, in particular, it is
not possible to actively access vehicle data.
The type of additional data processing is deter-
mined by the provider of the app being used.
Which settings can be made, if at all, depend
on the respective app and the operating sys-
tem of your smartphone. Online services
Wireless network connection If your vehicle has a wireless network connec-
tion, data can be exchanged between your
vehicle and other systems. The wireless net-
work connection is made possible by the vehi-
cle's own transceiver or by mobile end devices
that you have brought into the vehicle (e.g. smartphones). This wireless network connec-
tion can be used to access online functions.
This includes online services and apps provi-
ded by the manufacturer or other providers.
Services provided by the manufacturer In the case of the manufacturer's online serv-
ices, the manufacturer describes the functions
in a suitable place (e.g. manufacturer's operat-
ing instructions, website) and provides the
associated information subject to data protec-
tion legislation. Personal data may be used
when providing online services. The data
exchange for this takes place via a secure con-
nection, e.g. with the manufacturer's IT sys-
tems intended for the purpose. The collection,
the processing and the use of personal data
above and beyond the provision of services is
only permitted on the basis of a legal permit or
the consent of the person involved.
In most cases, you can enable or disable the
services and functions, some of which are sub-
ject to a charge. In some cases it will also
apply to the entire data connection of the vehi-
cle. There are exceptions to this; in particular,
legally prescribed functions and services such
as the "E-Call" traffic emergency call system.
Services provided by third parties If it is possible to use online services from
other providers, these services are the respon-
sibility of the provider in question and subject
to that provider's data protection conditions
and terms of use. The manufacturer has no
influence over the content exchanged in this
connection.
Please ask the respective service provider for
information on the type, extent and purpose of
the collection and use of personal data in the
context of services provided by third parties.36
