GWARNING
The function of systems or components can
be affected by conversions or modifications
to the vehicle. They might not function prop-
erly anymore and/or jeopardize the opera-
tional safety of the vehicle. There is an
increased risk of an accident and injury.
Conversions or modifications should always
be carried out at qualified specialist work-
shop.
If you intend to make modifications to your vehi-
cle, we strongly recommend that you contact
the distributor named on the inside of the front
cover. There you will receive all the necessary
information and a charge may be levied.
You alone accept the responsibility if body man-
ufacturers or dealers make modifications that
affect the final certification of the engine, the
vehicle or the equipment. This also applies to
the identification and documentation of modifi-
cations to the affected vehicle components.
You are responsible for certification and confir-
mation that:
Rall the applicable standards and regulations
that are affected by the vehicle modification
are met
Rthe modified vehicle fulfills the vehicle safety standards and emissions laws and regula-
tions

emissions laws and regulations or the motor
vehicle safety standards
Rany consequences arising from the changes
that make the vehicle less safe or even render it defective
We do not assume responsibility as the final-
stage manufacturer or for the consequential
product liability.
Notes on the radiator

HEnvironmental 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

RReliability
RSafety
RSuitability
Despite ongoing market research, Mercedes-
Benz is unable to assess other parts. Even if an
independent or official approval has been pro-
vided in exceptional cases, Mercedes-Benz
accepts no responsibility for the use of such
parts in Mercedes-Benz vehicles.
In some countries, certain parts are only offi-
cially approved for installation or modification if
they comply with legal requirements. All genu-
ine Mercedes-Benz parts satisfy these require-
ments. Make sure that all parts are suitable for
your vehicle.
Always specify the vehicle identification number
(VIN) (
Ypage 305) and engine number when
ordering genuine Mercedes-Benz parts
(
Ypage 306).

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 con-
tains the most important information on your
vehicle, e.g. the electric cable routes, in a com-
pact form.

your vehicle to operate safely, while some offer
support during driving (driver assistance sys-
tems). In addition, your vehicle offers comfort
and entertainment functions that are also made
possible by electronic control units.
Electronic control units contain data storage
systems that can temporarily or permanently save technical information concerning the vehi-
cle's condition, component stress and mainte-
nance requirements as well as technical events
and malfunctions.
This information generally documents the con-
dition of a component, a module, a system or the surroundings, for example:
Roperating states of system components (e.g.
fill levels, battery status, tire pressure)
Rstatus messages concerning the vehicle or its
individual components (e.g. number of wheel
revolutions/speed, deceleration in move-
ment, lateral acceleration, display of fastened
seat belts)
Rmalfunctions and defects in important system
components (e.g. lights, brakes)
Rinformation about events leading to vehicle
damage
Rsystem responses in special driving situations
(e.g. air bag deployment, intervention of sta-
bility control systems)
Rambient conditions (e.g. temperature, rain
sensor)
In addition to performing the actual control unit function, this data is used by manufacturers to
detect and rectify malfunctions and to optimize
vehicle functions. Most of this data is volatile
and processed only in the vehicle itself. Only a
small part of the data is stored in event or mal-
function 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
the vehicle's technical states, is used to help in
finding malfunctions and improving quality and
is sent to the manufacturer where necessary. Inaddition, the manufacturer is subject to product
liability. The manufacturer needs technical data
from vehicles for this purpose.
Malfunction memories in the vehicle can be
reset by a service center during repair or service
work.
You can incorporate data into the vehicle's com-
fort and infotainment functions y

ourself as part
of the selected equipment.
