Genuine Mercedes-Benz parts

Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
The operating safety of the vehicle could be
jeopardised if you use parts, tyres and wheels
that have not been approved by Mercedes-Benz.
This could lead to malfunctions in safety-rele-
vant systems, e.g. the brake system. Only use
genuine Mercedes-Benz parts or parts of equal
quality. Only use tyres and wheels approved for
your type of vehicle.
Mercedes-Benz checks genuine Mercedes-Benz
parts for:

Despite ongoing market research, Mercedes-
Benz is unable to assess other parts. Mercedes-
Benz therefore accepts no responsibility for the
use of such parts in Mercedes-Benz vehicles,
even if they have been independently or offi-
cially approved by a technical testing centre.
In the Federal Republic of Germany, certain
parts are officially approved for installation or
modification only if they comply with legal
requirements. This is also valid in several other
countries. All genuine Mercedes-Benz parts
meet the approval requirements. The use of
unapproved parts may result in the general
operating permit being invalidated.
This is the case if:
they cause a change to the vehicle type from
R
that for which the vehicle's general operating
permit was granted.
other road users could be endangered.
R
the emissions or noise levels are adversely

affected.
Always specify the vehicle identification number
(VIN) when ordering genuine Mercedes-Benz
Y
parts (

Data stored in the vehicle
Information from electronic control
units
There are electronic control units installed in
your vehicle. Some of these are required for the
safe functioning of your vehicle, some support
you while driving (driver assistance systems).
Your vehicle also offers a range of comfort or
entertainment functions, which are also con-
trolled by the electronic control units.
Electronic control units contain data memories
that can temporarily or permanently store tech-
nical information about the vehicle's operating
state, component loading, maintenance require-
ments as well as technical events and faults.
This information generally documents the con-
dition of a component, a module, a system or the
surroundings, for example:
Operating states of system components (e.g.
R
fill levels, battery status, tyre pressure)
Status messages concerning the vehicle or its
R
individual components (e.g. number of wheel
revolutions/speed, deceleration in move-
ment, lateral acceleration, display of fastened
seat belts)
Malfunctions and defects in important system
R
components (e.g. lights, brakes)
information concerning events that may dam-
R
age the vehicle
System responses in special driving situa-
R
tions (e.g. airbag deployment, intervention of
stability control systems)
Ambient conditions (e.g. temperature, rain
R
sensor)
In addition to performing the actual control unit
function, this data is used by manufacturers to
detect and rectify faults and to optimise vehicle
functions. Most of this data is stored in volatile
memory and processed only in the vehicle itself.
Only a small part of the data is stored in event or
fault memories.
When you use services, the technical data from
the vehicle can be read out by service network
employees or third parties. Services can include
repair services, maintenance processes, war-
ranty cases and quality assurance measures.
The data is read out via the connection for OBD
(European on-board diagnostics) in the vehicle,
which is required by law. The relevant offices in
the service network or third parties collect,
process and use the data. This data documents
