Genuine Mercedes-Benz/DTNA parts

Environmental note
We supply reconditioned assemblies and
parts which are of the same quality as new
parts. The same New Vehicle Limited War-
ranty applies as for new parts.
If you use parts, tires or wheels which have
not been approved by Mercedes-Benz/DTNA,
the operating safety of the vehicle may be
impaired. This could lead to malfunctions in
safety-relevant systems, e.g. the brake sys-
tem. Only use genuine Mercedes-Benz/DTNA
parts or parts of a similar quality. Only use
tires and wheels that have been specifically
approved for your vehicle.
Mercedes-Benz/DTNA tests genuine parts, as
well as conversion parts and accessories
approved for your vehicle model for:
R
Reliability
R
Safety
R
Suitability
Despite ongoing market research, Mercedes-
Benz/DTNA is unable to assess other parts.
We therefore accept no responsibility for the
use of such parts in Freightliner vehicles, even
if they have been independently or officially
approved by a technical testing center.
In some countries, certain parts are only offi-
cially approved for installation or modification
if they comply with legal requirements. All gen-
uine Mercedes-Benz/DTNA parts satisfy these
requirements. Make sure that the parts are
suitable for your vehicle.
Always specify the vehicle identification num-
ber (VIN) and the engine number
(

page 197) when ordering genuine
Mercedes-Benz/DTNA parts.
Data stored in the vehicle
Electronic control units
Electronic control units are installed in your
vehicle. Some of these are necessary for the
safe operation of your vehicle, while some
assist you when driving (driver assistance sys-
tems). In addition, your vehicle provides com-
fort and entertainment functions, which are
also made possible by electronic control units.
Electronic control units contain data memories
which can temporarily or permanently store
technical information about the vehicle's oper-
ating state, component loads, maintenance
requirements and technical events or malfunc-
tions.
In general, this information documents the
state of a component part, a module, a system
or the surroundings such as:
R
operating statuses of system components
(e.g. fluid levels, battery status, tire pres-
sure)
R
status messages concerning the vehicle and
its individual components (e.g. number of
wheel revolutions/speed, deceleration, lat-
eral acceleration, display of the fastened
seat belts)
R
malfunctions or defects in important system
components (e.g. lights, brakes)
R
information on vehicle damage events
R
system reactions in special driving situa-
tions (e.g. air bag deployment, intervention
of stability control systems)
R
ambient conditions (e.g. temperature, rain
sensor)
In addition to providing the actual control unit
function, this data assists the manufacturer in
detecting and rectifying malfunctions and opti-
mizing vehicle functions. The majority of this
data is temporary and is only processed in the
vehicle itself. Only a small portion of the data
is stored in the event or fault memory.
When service work is done on your vehicle, the
technical data from the vehicle can be read
out by service network staff (e.g. workshops,
manufacturer) or third parties (e.g. breakdown
services). Services include repair services,
maintenance processes, warranty events and
quality assurance measures, for example. The
read out is performed via the legally prescri-
bed port for the diagnostics connection in the
vehicle. The respective service network loca-
tions or third parties collect, process and use
the data. They document technical statuses of
the vehicle, assist in finding malfunctions and
improving quality and are transmitted to the
manufacturer, if necessary. Furthermore, the
manufacturer is subject to product liability. For
