vehicle. This also includes labeling and docu-
mentation affected by their modifications.
It is their responsibility to certify that:
R the altered vehicle conforms to all applica-
ble standards and regulations affected by
the vehicle alteration
R the altered vehicle continues to comply with
the motor vehicle safety standards and
emissions regulations
R the changes or installation of accessories do
not impair the safety of the vehicle
We are not responsible for any final certifica-
tion or claims regarding product liability or
warranty claims that arise as a result of such
changes. This applies to:
R components, assemblies or systems which
have been altered
R non-compliance with emissions laws and
regulations or with vehicle safety standards
arising as a result of the alterations
R all consequences resulting form the
changed, less safe or even defective vehicle
We do not assume responsibility as the final
stage manufacturer or the consequential prod-
uct liability.
Notes on the engine radiator Even seemingly small changes to the vehicle,
such as attaching a radiator trim for winter
driving or as protection against insects, are
not permitted. Do not cover the radiator. Do
not use thermal mats, insect protection covers
or anything similar.
Doing so can cause the diagnostics system to
display inaccurate values. Some of these val-
ues are legally required and must always be
correct.
Notes for commercial vehicles without
partitions Vehicles, which are approved as commercial
vehicles (N1), do not comply with the
ISO 27956
standard in the respective current
valid version unless equipped with a partition.
The ISO 27956 Standard details the equip-
ment for correct load securing in delivery vehi-
cles. Retrofitting the partition is strongly rec-
ommended when using the vehicle for the
transport of goods, as correct load securing in
vehicles without the partition is difficult to
achieve. Genuine Mercedes-Benz parts
! Air bags and Emergency Tensioning Devi-
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R cockpit
R instrument cluster
R center console
Do not install accessories such as audio sys-
tems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have aftermarket accessories installed at a
qualified specialist workshop. H
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.
The operating safety of the vehicle could be
jeopardized if you use parts, tires and wheels
as well as accessories relevant to safety which
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 tires, wheels and accessories
that have been specifically approved for your
vehicle.
Mercedes-Benz tests genuine Mercedes-Benz
parts, conversion parts and accessories that
have been specifically approved for the type of
vehicle for:
R Reliability
R Safety
R Suitability
Despite ongoing market research, Mercedes-
Benz is unable to assess other parts. Even if
an independent or official approval has been
provided in exceptional cases, Mercedes-Benz
accepts no responsibility for the use of such
parts in Mercedes-Benz vehicles. 34
Introduction

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
