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 parts satisfy these
requirements. Make sure that all parts are
suitable for your vehicle.
Always specify the vehicle identification num-
ber (VIN) ( Y page
304) and engine number
when ordering genuine Mercedes-Benz parts
(Y page 305). QR code for rescue card
The QR Code stickers are affixed to the B-pillar
on the driver's and front-passenger side.
In the event of an accident the rescue services
use the QR Code to quickly find the rescue
card for your vehicle. The current rescue card
contains the most important information on
your vehicle, e.g. the electric cable routes, in a
compact form.
Further information can be found at http://
www.mercedes-benz.de/qr-code. Data stored in the vehicle
Electronic control units
Electronic control units are installed in your
vehicle. Some of them are necessary to ensure
that your vehicle functions safely, some are
there to support the driver (driver assistance
systems). In addition to that, your vehicle
offers convenience and entertainment func-
tions which are also made possible by the use
of electronic control units.
Electronic control units contain data memories
which can store technical information on the
vehicle's operating state, component stress,
maintenance requirements as well as technical
events and malfunctions either temporarily or
permanently.
In general, this information documents the sta-
tus of a component, a module, a system or the
surroundings, for example:
R operating states of system components (e.g.
fill levels, battery status, tire pressure)
R status messages concerning the vehicle or
its individual components (e.g. number of
wheel revolutions/speed, deceleration in movement, lateral acceleration, display of
fastened seat belts)
R malfunctions and defects in important sys-
tem components (e.g. lights, brakes)
R information on events damaging the vehicle
R system responses 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 the underlying control unit func-
tion, this data can be used for the detection
and the rectification of malfunctions as well as
the optimization of vehicle functions by the
manufacturer. Most of this data is volatile and
is only processed in the vehicle itself. Only a
small proportion of the data is stored in event
or malfunction memories.
When you use services, the technical data
from the vehicle can be read out by service
network employees (e.g. workshops, manufac-
turers) or third parties (e.g. breakdown serv-
ices). Services can include repair services,
maintenance processes, warranty cases and
quality assurance measures. Data is read out
using the legally prescribed diagnostics con-
nection in the vehicle. The respective repre-
sentatives of the service network or third par-
ties collect, process and use the data. It docu-
ments technical states of the vehicle, helps
staff to find malfunctions and improve quality
and, in certain cases, is passed on to the man-
ufacturer. Furthermore, the manufacturer is
subject to product liability provisions. For this
reason, the manufacturer requires technical
data from vehicles.
Malfunction memories in the vehicle can be
reset within the scope of the repair or service
work carried out by a service outlet.
Depending on the equipment selected, you
can add data to the convenience and infotain-
ment functions of the vehicle yourself.
These include:
R multimedia data, such as music, films or
photos for playback in an integrated multi-
media system
R address book data for use in connection
with an integrated hands-free system or an
integrated navigation system
R navigation destinations entered
R data on the utilization of Internet services Introduction
