Engine system
The 4R 1000 and 6R 1000 series of engines
only function as intended when used in con-
junction with the corresponding exhaust gas
aftertreatment unit. Therefore, in these Oper-
ating Instructions, the term "engine system"
refers to the engine and the exhaust gas after-
treatment unit.
Protection of the environment
H
Environmental note
Daimler AG has a declared policy of compre-
hensive environmental protection.
The objectives are to use the natural resour-
ces which form the basis of our existence on
this planet sparingly and in a manner which
takes the requirements of both nature and
humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Information and notes on driving in an envi-
ronmentally responsible and fuel-saving man-
ner can be found in the "Operating notes"
section (Y page 42).
Assembly equipment
These Operating Instructions describe all
models and all standard and optional equip-
ment available for your engine system at the
time of publication of the Operating Instruc-
tions. Country-specific deviations are possi-
ble. Note that your engine system may not be
fitted with all features described. This also
applies to safety-relevant systems and func-
tions. Therefore, the equipment on your
engine system may differ from certain
descriptions and illustrations.
All of the components in your engine system
are listed in the data card of your engine sys-
tem. Data card (Y page 72).
Please contact an MTU or MTU-authorised
Mercedes-Benz Service Centre if you have
any questions about the equipment or oper-
ation.
Genuine Mercedes-Benz parts
H
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.
If you use parts which have not been
approved by Mercedes-Benz, the operational
safety of the engine system may be jeopar-
dised. This could lead to malfunctions in
safety-relevant systems. Use only genuine
Mercedes-Benz parts or parts of equal qual-
ity. Only use parts that have been approved
for your engine type.
Mercedes-Benz checks genuine Mercedes-
Benz parts for:
R
reliability
R
safety
R
suitability
Despite ongoing market research, Mercedes-
Benz is unable to assess other parts.
Mercedes-Benz therefore accepts no respon-
sibility for the use of such parts in Mercedes-
Benz vehicles, even if they have been officially
approved or independently approved by a
testing centre.
In Germany, certain parts are only officially
approved for installation or modification if
they comply with legal requirements. This
also applies to some other countries. All gen-
uine Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts
may invalidate the vehicle's general operating
permit.
