are used to help in finding malfunctions and
improving quality and are sent to the manufac-
turer where necessary. In addition, the manu-
facturer is subject to product liability. The man-
ufacturer needs technical data from vehicles for
this purpose.
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:
Rmultimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
Raddress book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
Rnavigation destinations that have been
entered
Rdata about using Internet services
These data can be saved locally in the vehicle or
are located on a device that you have connected
to the vehicle. If this data is saved in the vehicle,
you can delete it at any time. These data are sent
to third parties only at your request, particularly
when you use online services in accordance with
the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the piece of equipment in ques-
t

ion, these can include, for example:
Rseat and steering wheel position settings
Rsuspension and climate control settings
Rcustom 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:
Rgeneral vehicle information
Rposition 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.
Service provider
Wireless network connection
If your vehicle has a wireless network connec-
tion, data can be exchanged between your vehi-
cle and other systems. The wireless network
connection is enabled by either an in-vehicle
transmitter and receiver or your own mobile end
device (e.g. smartphone). Online functions can
be used via this wireless network connection.
These include online services and applications/ Apps provided 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 and the associated informa-
tion subject to data protection legislation. Per-
sonal data can be used in order to provide online
services. Data are exchanged via a secure con-
nection (e.g. using the IT system specially pro-
vided for this purpose by the manufacturer).
Collecting, processing and using personal data
beyond the provision of services is permitted
only on the basis of a statutory permit or decla-
ration of consent.
You can usually activate and deactivate the serv-
ices and functions (some of which are subject to
charge). In many cases, this also applies to the
vehicle's entire data connection. However, this
does not apply in particular to legally prescribed
functions and services such as the "eCall" emer-
gency call system.
Services from third parties
If it is possible to use online services from other
providers, these services are the responsibility
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 here.

required to steer and brake than is normally
required. There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely.
GWARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible
gross weight of your vehicle, the:
Rthe towing eye could detach itself
Rthe vehicle/trailer combination could roll-
over.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
Details on the permissible gross vehicle weight
of your vehicle can be found on the vehicle iden-
tification plate (
Ypage 285).
