Data
storage Electronic control units
Elect
ronic control units are fitted in your vehicle.
Some of these are necessary forth e safe opera‐
tion of your vehicle, while some assist you when
driving (driver assis tance sy stems). In addition,
yo ur vehicle pr ovides com fort and enter tainment
functions, which are also made possible byelec‐
tronic control units.
Elect ronic control units contain da tamemories
which can temp orarily or permanently store
te ch nical information about theve hicle's operat‐
ing state, component loads, main tenance
re qu irements and tech nical events or faults.
In general, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings such as:
R operating status of sy stem components (e.g.
fi ll le vels, battery status, tyre pressure)
R status messages concerning theve hicle or
its individual components (e.g. number of
wheel revo lutions/speed, longitudinal accel‐ eration, lateral acceleration, display of
fas‐
te ned seat belts)
R malfunctions or faults in impor tant sy stem
components (e.g. lights, brakes)
R information on events leading tovehicle
damage
R system reactions in special driving situations
(e.g. airbag deployment, inter vention of sta‐
bility control sy stems)
R ambient conditions (e.g. temp erature, rain
sensor)
In addition toprov iding the actual control unit
function, this data assists the manufacturer in
de tecting and rectifying faults and optimising
ve hicle functions. The majority of this data is
te mp orary and is only processed in theve hicle
itself. Only a small portion of the data is stored
in theeve nt or fault memor y.
When your vehicle is serviced, tech nical da ta
from theve hicle can be read out byservice net‐
wo rkemplo yees (e.g. workshops, manufactur‐
ers) or third parties (e.g. breakdown services).
Services include repair services, maintenance
processes, warranty claims and quality assur‐ ance measures,
forex ample. The read out is per‐
fo rm ed via the legally prescribed port forthe
diagnostics connection in theve hicle. The
re spective service network locations or third
parties collect, process and use the data. They
document tech nical statuses of theve hicle,
assist in finding faults and impr oving quality and
are transmitted tothe manufacturer, if neces‐
sar y.Fu rthermore, the manufacturer is subject
to product liability. Forth is, the manufacturer
requ irestech nical da tafrom vehicles.
Fa ult memories in theve hicle can be reset by a
service outlet as part of repair or maintenance
wo rk.
Depending on the selected equipment, you can
import data into vehicle con venience and info‐
ta inment functions yourself.
This includes, forex ample:
R multimedia data such as music, films or pho‐
to sfo r playback in an integrated multimedia
sy stem
R address book data for use in connection with
an integrated hands-free sy stem or an inte‐
grated navigation sy stem 30

R data about the use of internet services
This data can be sa ved locally in theve hicle or it
is located on a device which you ha veconnected
to theve hicle (e.g. a smartphone, USB flash
drive or MP3 pla yer). If this data is stored in the
ve hicle, you can dele teit at any time. This data
is sent tothird parties only at your requ est, par‐
ticular lywhen you use online services in accord‐
ance with the settings that you ha veselected.
Yo u can store or change con venience settings/
individualisations in theve hicle at any time.
Depending on the equipment, this includes, for
ex ample:
R settings forth e seat and steering wheel posi‐
tions
R suspension and climate control settings
R customisations such as interior lighting
If yo ur vehicle is accordingly equipped, you can
connect your smartphone or ano ther mobile end
device totheve hicle. You can cont rolth is by
means of the control elements integrated in the
ve hicle. Images and audio from the smartphone can be output via
the multimedia sy stem. Cer‐
ta in information is simultaneously transfer redto
yo ur smartphone.
Depending on the type of integration, this can
include:
R general vehicle data
R position data
This allo wsyouto use selected apps on your
smartphone, such as navigation or music play‐
bac k.There is no fur ther interaction between the
smartphone and theve hicle; in particular, vehi‐
cle data is not directly accessible. Which type of
fur ther data processing occurs is de term ined by
th e pr ovider of the specific app used. Which set‐
tings you can make, if an y,depends on the spe‐
cific app and the operating sy stem of your
smartphone. Online services
Wire
less network connection
If yo ur vehicle has a wireless network connec‐
tion, it enables data tobe exc hanged between
yo ur vehicle and additional sy stems. The wire‐ less network connection is enabled via
theve hi‐
cle's transmission and reception unit or via con‐
nected mobile end devices (e.g. sma rtphones).
Online functions can be used via the wireless
network connection. This includes online serv‐
ices and applications/apps pr ovided bythe man‐
ufacturer or other pr oviders.
Manu factu rer's se rvices
Re garding online services of the manufacturer,
th e individual functions are described bythe
manufacturer in a suita ble place (e.g. Owner's
Manual, website of the manufacturer) along with
th ere leva nt da taprotection information. Per‐
sonal data may be used forth e pr ovision of
online services. Data is exchanged via a secure
connection, e.g. the manufacturer's designated
IT sy stems. Personal data is collected, pro‐
cessed and used via the pr ovision of services
ex clusively on the basis of legal permissions or
with prior consent.
The services and functions (sometimes subject
to afe e) can usually be activated or deactivated.
In some cases, this also applies tothe entire
ve hicle's data connection. This excludes, in par‐
ticular, legally prescribed functions and services. General no

WARNING Risk of inju rydue tomodifi‐
cations tothe airbag co ver
If yo u modify the co ver of an airbag or af fix
objects such as sticke rs to it,the airbag may
no longer function cor rectly. #
Never modify the co ver of an airbag and
do not af fix objects toit. The ins
tallation location of an airbag is identified
by the AIRB AGsymbol (/ page 40). &
WARNING Risk of inju ryor death due to
th e use of unsuitable seat co vers
Uns uitable seat co vers can obstruct or pre‐
ve nt the deployment of the airbags integra‐
te d into the seats.
Consequentl y,the airbags cann otprotect
ve hicle occupants as they are designed to
do. In addition, the operation of the auto‐
matic front passenger airbag shutoff could
be restricted. #
You should on lyuse seat co vers that

WARNING Risk of inju rydue tomalfunc‐
tions of the sensors in the door panelling
Sensors tocontrol the airbags are located in
th e doors. Modifications or worknot per‐
fo rm ed cor rectly tothe doors or door panel‐
ling, as well as damaged doors, can lead to
th e function of the sensors being impaired.
The airbags might therefore not function
