Data storage

Data processing in the vehicle

Electronic control units

There are electronic control units installed in your

vehicle. Control units process data that they e.g.

receive from vehicle sensors, generate them-

selves or exchange among themselves. Some

control units are required for the safe operation of

your vehicle. For example, some assist you when

you are driving, such as driver assistance sys-

tems, while others enable convenience or infotain-

ment functions.

The following provides you with general informa-

tion regarding data processing in the vehicle.

Additional information on what specic data is

collected, stored and transmitted to third parties

for what purpose in your vehicle can be found in

the notes on the functional features in question in

the respective operating instructions. These are

also available online and, depending on the equip-

ment, digitally in the vehicle.

Personal data

Each vehicle is marked with a unique vehicle iden-

tication number. Depending on the country, this

vehicle identication number can be used by, for

example, government authorities to determine the

identity of the owner. There are other possibilities

for using data collected from the vehicle to iden-

tify the owner or driver, such as the license plate

number.

The data generated or processed by control units

may therefore be personal or, in certain circum-

stances, become personal. Depending on which

vehicle data are available, it may be possible to

make inferences about, for example, your driving

behavior, your location, your route or your use

patterns.

Legal requirements for the disclosure of data

If legal regulations exist, manufacturers are gener-

ally obligated to release data stored by the manu-

facturer to the necessary extent in individual

cases at the request of state authorities. This may

be the case during the investigation of a criminal

oense, for example.

Within the framework of applicable law, state

authorities are also authorized to take data read-

outs from vehicles themselves in specic cases.

In the event of an accident, for example, informa-

tion readouts can be taken from the air bag con-

trol unit to help to establish what happened.

Operating data in the vehicle

Control units process data to operate the vehicle.

This includes the following data, for example:

Vehicle status information such as speed, lon-

gitudinal acceleration, lateral acceleration,

number of wheel revolutions or the fastened

seat belts indicator

Ambient conditions, such as temperature, rain

sensor or distance sensor

General notes

As a rule, this data is volatile, is not stored beyond

the operating time and is processed only in the

vehicle itself. Control units (e.g. the vehicle key)

oen contain data memories. These are used to

temporarily or permanently document information

about the vehicle's operating state, component

stress, maintenance requirements or technical

events and malfunctions.

Depending on the technical equipment, the fol-

lowing data will be stored:

Operating status of system components (e.g.

ll levels, tire pressure, battery status)

Malfunctions or faults in important system

components (e.g. lights, brakes)

System reactions in special driving situations

(e.g. air bag deployment, the intervention of

stability control systems

Information on events leading to vehicle dam-

age

In special cases, it may be necessary to store

data that would otherwise only be volatile. This

may be the case if the vehicle has detected a mal-

function, for example.

If you use services such as repair services or

maintenance work, stored operational data read-

outs can be taken and used together with the

vehicle identication number, where necessary.

Readouts can be taken by service network

employees such as workshops and manufactur-

ers, or third parties, such as breakdown services.

The same is true in the case of warranty claims

and quality assurance measures.

The readout will usually be taken via the diagnos-

tics connection in the vehicle, which is required

by law. The operating data readout taken docu-

ments technical conditions of the vehicle or indi-

vidual components and helps to diagnose mal-

functions, meet warranty obligations and improve

quality. This data, particularly information on com-

ponent stress, technical events, operating errors

and other malfunctions, will be transmitted to the

manufacturer for this purpose together with the

vehicle identication number if necessary. In addi-

tion, the manufacturer is subject to product liabil-

ity. For this reason, the manufacturer also uses

operational data from the vehicle for e.g. recalls.

This data can also be used to check customer

claims for warranty and guarantee.

Fault memories in the vehicle can be reset by a

service outlet or at your request as part of repair

or maintenance work.

Comfort and infotainment functions

You can save comfort settings and individualiza-

tion in the vehicle and change or reset them at

any time.

Depending on the vehicle equipment, this

includes the following settings, for example:

Seat positions and steering wheel positions

Suspension tuning and climate control set-

tings

Custom settings (e.g. interior lighting)

You can incorporate data into the vehicle's info-

tainment functions yourself as part of the selec-

ted equipment.

Depending on the vehicle equipment, this

includes the following data, for example:

Multimedia data (e.g. music, lms or photos

for playback in an integrated multimedia sys-

tem)

General notes

Address book data for use in conjunction with

an integrated hands-free system or an integra-

ted navigation system

Navigation destinations that have been

entered

Data about the use of internet services

This data for comfort and infotainment functions

can be saved locally in the vehicle or stored on a

device that you have connected to the vehicle

(e.g. smartphone, USB ash drive or MP3 player).

If you have entered data yourself, you can delete

it at any time.

The transfer of this data out of the vehicle will

take place exclusively at your request. This applies

in particular when you are using online services

according to the settings you have selected.

Smartphone integration (e.g. Android Auto or

Apple CarPlay

)

If your vehicle is equipped appropriately, you can

connect your smartphone or another mobile

device to the vehicle. You will then be able to con-

trol them using the controls integrated in the vehi-

cle. The smartphone's picture and sound can be

output via the multimedia system. Specic items

of information will also be transferred to your

smartphone. Depending on the type of integra-

tion, this may include position data, day/night

mode and other general vehicle statuses. Please

refer to the vehicle Operator's Manual / infotain-

ment system operating instructions for further

information.

This integration allows the use of selected smart-

phone apps (e.g. navigation apps, music player

apps). There will be no further interaction

between your smartphone and the vehicle; in par-

ticular, vehicle data will not be directly accessible.

The type of additional data processing is deter-

mined by the provider of the app being used.

Whether you can congure settings for it and, if

so, which ones, depend on the app and your

smartphone's operating system.

Online services

Wireless network connection

If your vehicle has a wireless network connection,

it enables data to be exchanged between your

vehicle and additional systems. The wireless net-

work connection is made possible by the vehicle's

own transmitter and receiver or by a mobile end

device 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's services

Regarding the manufacturer's online services, the

individual functions are described by the manu-

facturer in a suitable place, for example, in the

Operator's Manual or on the manufacturer's 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's 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 contractual

agreement or when consent has been given.

General notes

You can have services and functions, some of

which are subject to a fee, activated or deactiva-

ted. This excludes legally prescribed functions and

services, such as an emergency call system.

Third-party services

If 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's data protection conditions and terms of

use. As a general rule, the manufacturer has no

inuence on the content exchanged.

For this reason, when services are provided by

third parties, please ask the service provider in

question for information about the type, extent

and purpose of the collection and use of personal

data.

Data protection rights

Depending on your country or the equipment and

range of functions of your vehicle as well as the

services you use and the services on oer, you

are entitled to dierent data protection rights.

Further information on data protection and your

data protection rights can either be found on the

manufacturer's website or you will receive this

information as part of the various services and

service oers. There you will also nd the contact

information for the manufacturer and its data pro-

tection ocers.

At a workshop, for example, with the support of a

specialist and possibly for a fee, you can have

data read out which is stored only locally in the

vehicle.

MBUX multimedia system/Mercedes me connect

If the vehicle is equipped with the MBUX multime-

dia system or Mercedes me connect, additional

data about the vehicle's operation, the use of the

vehicle in certain situations, and the location of

the vehicle may be compiled by the MBUX multi-

media system or Mercedes me connect.

For additional information, please refer to the

"MBUX multimedia system" section and/or the

Mercedes me connect Terms and Conditions.

Event data recorder

USA only:

This vehicle is equipped with an event data

recorder (EDR). The main purpose of an EDR is to

record, in certain crash or near crash-like situa-

tions, such as an air bag deployment or hitting a

road obstacle, data that will assist in understand-

ing how a vehicle’s systems performed. The EDR

is designed to record data related to vehicle

dynamics and safety systems for a short period of

time, typically 30 seconds or less.

The EDR in this vehicle is designed to record such

data as:

How various systems in your vehicle were

operating;

Whether or not the driver and passenger

safety belts were buckled/fastened;

How far (if at all) the driver was depressing the

accelerator and/or brake pedal; and,

How fast the vehicle was traveling.

These data can help provide a better understand-

ing of the circumstances in which crashes and

injuries occur. NOTE: EDR data are recorded by

your vehicle only if a non-trivial crash situation

occurs; no data are recorded by the EDR under

General notes

normal driving conditions and no personal data

(e.g., name, gender, age, and crash location) are

recorded. However, other parties, such as law

enforcement could combine the EDR data with

the type of personally identifying data routinely

acquired during a crash investigation.

To read data recorded by an EDR, special equip-

ment is required, and access to the vehicle or the

EDR is needed. In addition to the vehicle manu-

facturer, other parties, such as law enforcement,

that have the special equipment, can read the

information if they have access to the vehicle or

the EDR.

EDR data may be used in civil and criminal mat-

ters as a tool in accident reconstruction, accident

claims, and vehicle safety. Since the Crash Data

Retrieval CDR tool that is used to extract data

from the EDR is commercially available,

Mercedes-Benz USA, LLC („MBUSA“) expressly

disclaims any and all liability arising from the

extraction of this information by unauthorized

Mercedes-Benz personnel.

MBUSA will not share EDR data with others with-

out the consent of the vehicle owners or, if the

vehicle is leased, without the consent of the les-

see. Exceptions to this representation include

responses to subpoenas by law enforcement; by

federal, state or local government; in connection

with or arising out of litigation involving MBUSA or

its subsidiaries and aliates; or, as required by

law.

Warning: The EDR is a component of the Restraint

System Module. Tampering with, altering, modify-

ing or removing the EDR component may result in

a malfunction of the Restraint System Module and

other systems.

State laws or regulations regarding EDRs that

conict with federal regulation are pre\-empted.

This means that in the event of such conict, the

federal regulation governs. As of Dec 2016, 17

states have enacted laws relating to EDRs.
