Notes for persons with electronic medical aids
Mercedes-Benz AG cannot, despite carefully
developing vehicle systems, completely rule out
the interaction of vehicle systems with electronic medical aids such as cardiac pacemakers.
In addition, there are components installed in the
vehicle that, regardless of the operating status of
the vehicle, can generate magnetic Nelds on a par
with permanent magnets. These Nelds can be
found, for example, in the area around the multi- media and sound system or also in the area of theseats, depending on the vehicle equipment.
For this reason, the following can occur in isolatedcases, depending on the aids used:
= Medical aids malfunctioning
= Adverse health eMects
Observe the notes and warnings of the manufac- turer of the medical aids; if in doubt, contact thedevice manufacturer and/or your doctor. If there is continuing uncertainty concerning the possibil-ity of medical aids malfunctioning, Mercedes-
Benz AG recommends using only few electricalvehicle systems and/or maintaining a distance
from the components.
Only have repairs and maintenance work in the
area of the following components carried out at a
qualiNed specialist workshop:
= Vehicle components carrying live voltage
= Transmission antenna
= Multimedia system and sound system
If you have any queries or suggestions, consult a
qualiNed specialist workshop.

Data storage
Data processing in the vehicle
Electronic control units
Electronic control units are installed in your vehi- cle. Control units process data which, for exam-
ple, they receive from vehicle sensors, generate themselves or exchange between themselves. Some control units are required for the safe oper-ation of your vehicle, some assist you when driv-
ing, such as driver assistance systems, while oth- ers enable convenience or infotainment functions.
The following provides you with general informa- tion regarding data processing in the vehicle.
Additional information regarding exactly which
data in your vehicle are collected, saved and
transmitted to third parties, and for what purpose, can be found in the information directly related to
the functional characteristics in question in their respective operating instructions. This information
is also available online and, depending on the
vehicle equipment, digitally.
Personal data
Every vehicle is identiNed by a unique vehicle
identiNcation number. Depending on the country,
this vehicle identiNcation number can be used by,
for example, governmental authorities to deter-
mine the identity of the owner. There are other
possibilities to use data collected from the vehicle to identify the owner or driver, such as the license
plate number.
Therefore, data generated or processed by control units may be attributable to a person or, under certain conditions, become attributable to a per-
son. Depending on which vehicle data are availa-
ble, it may be possible to make inferences about,
for example, your driving behavior, your location,
your route or your use patterns.
Legal requirements regarding the disclosure of
data
If legally required to do so, manufacturers are, in
individual cases, legally obliged to provide govern-
mental entities, upon request and to the extent required, data stored by the manufacturer. For
example, this may be the case during the investi- gation of a criminal oMense.Governmental entities are themselves, in individ-
ual cases and within the applicable legal frame- work, authorized to read out data from the vehi-cle. In the case of an accident, information thatcan help with an investigation can, therefore, be
taken from the air bag control unit, for example.
Operational data in the vehicle
This is data regarding the operation of the vehicle,
which have been processed by control units.
This includes the following data, for example:
= vehicle status information such as the speed,
longitudinal acceleration, lateral acceleration,
number of wheel revolutions or the fastened
seat belts display
= ambient conditions, such as temperature, rain
sensor or distance sensor
Generally, the use of these data is temporary;
they will not be stored beyond the period of oper- ation and will only be processed within the vehicleitself. Control units osen contain data memories
for vehicle keys, for example. Their use permits
the temporary or permanent documentation of
technical information about the vehicle\bs operat-28General notes

ing state, component loads, maintenance require-
ments and technical events or malfunctions.
Depending on the vehicle equipment, the follow-
ing data are stored:
= operating status of system components, such
as Nll levels, tire pressure or battery status
= malfunctions or faults in important system
components, such as lights or brakes
= system reactions in special driving situations,
such as air bag deployment or the intervention of stability control systems
= information on events leading to vehicle dam-
age
In certain cases, it may be required to store data
that would have otherwise been used only tempo-
rarily. This may be the case if the vehicle has detected a malfunction, for example.
If you use services, such as repair services and
maintenance work, stored operational data as well as the vehicle identiNcation number can be
read out and used. They can be read out by
service network employees, such as workshops and manufacturers or third parties, such as break-down services. The same is true in the case ofwarranty claims and quality assurance measures.
In general, the readout is performed via the legally
prescribed port for the diagnostics connection in
the vehicle. The operational data that are read out document technical states of the vehicle or ofindividual components and assist in the diagnosisof malfunctions, compliance with warranty obliga-
tions and quality improvement. To that end, these
data, in particular information about component loads, technical events, malfunctions and otherfaults may be transmitted along with the vehicleidentiNcation number to the manufacturer. Fur-
thermore, the manufacturer is subject to product
liability. For this reason the manufacturer also
uses operational data from the vehicle, for exam-
ple, for recalls. These data can also be used to
examine the customer\bs warranty and guarantee
claims.
Malfunction memories in the vehicle can be reset
by a service outlet or at your request as part of
repair or maintenance work.Convenience and infotainment functions
You can store convenience settings and individual
settings in the vehicle and change or reset them at any time.
Depending on the vehicle equipment, this
includes the following settings, for example:
= seat and steering wheel positions
= suspension and climate control settings
= individual settings, such as interior lighting
Depending on the selected equipment, you can
import data into vehicle infotainment functions
yourself.
Depending on the vehicle equipment, this
includes the following data, for example:
= multimedia data, such as music, Nlms or pho-
tos for playback in an integrated multimedia system
= address book data for use in connection with
an integrated hands-free system or an integra-
ted navigation system
= entered navigation destinations
= data about the use of Internet servicesGeneral notes29

These data for convenience and infotainment
functions may be saved locally in the vehicle or
they may be located on a device which you have
connected to the vehicle, such as a smartphone,
USB Oash drive or MP3 player. If you have entered
these data yourself, you can delete them at any time.
This data is transmitted from the vehicle to third
parties only at your request. This applies, in par-
ticular, when you use online services in accord-
ance with the settings that you have selected.
Smartphone integration (e.g. Android Auto or Apple CarPlay n
)
If your vehicle is accordingly equipped, you can connect your smartphone or another mobile end
device to the vehicle. You can then control them by means of the control elements integrated in
the vehicle. Images and audio from the smart-
phone can be output via the multimedia system. Certain information is simultaneously transferred
to your smartphone. Depending on the type and integration, this includes position data, day/night
mode and other general vehicle statuses. For more information please consult the Operator\bsManual of the vehicle/infotainment system.This integration allows the use of selected smart-phone apps, such as navigation or music playerapps. There is no further interaction between the
smartphone and the vehicle; in particular, vehicle
data is not directly accessible. The type of addi- tional data processing is determined by the pro-vider of the app being used. Which settings youcan make, if any, depends on the speciNc app and
the operating system of your smartphone.
Online services
Wireless network connection
If your vehicle has a wireless network connection, it enables data to be exchanged between yourvehicle and additional systems. The wireless net-
work connection is made possible by the vehicle\bs own transmitter and receiver or by a mobile enddevice that you have brought into the vehicle, for
example, a smartphone. Online functions can be
used via the wireless network connection. This
includes online services and applications/apps
provided to you by the manufacturer or by other
providers.
Manufacturer\bs services
Regarding the manufacturer\bs online services, the
individual functions are described by the manu- facturer in a suitable place, for example, in theOperator\bs Manual or on the manufacturer\bs web-
site, where the relevant data protection informa-
tion is also given. Personal data may be used for
the provision of online services. Data is
exchanged via a secure connection, such as the manufacturer\bs designated IT systems. Any per-
sonal data which is collected, processed and
used, other than for the provision of services, is
done so exclusively on the basis of legal permis-
sion. This is the case, for example, for a legally prescribed emergency call system, a contractualagreement or when consent has been given.
You can have services and functions, some ofwhich are subject to a fee, activated or deactiva-
ted. This excludes legally prescribed functions and
services, such as an emergency call system.
Third-party servicesIf you use online services from other providers (third parties), these services are the responsibil-
ity of the provider in question and subject to that provider\bs data protection conditions and terms of30General notes
