Proper use
Observe the following information when oper-
ating your vehicle:
Rthe safety notes in these operating instruc-
tions
Rthe technical data in these operating instruc-tions
Rtraffic laws and regulations
Rmotor vehicle laws and safety standards
There are various warning stickers affixed to the
vehicle. If you remove warning stickers, you and
others may fail to recognize the dangers. Leave
the warning stickers in their original position.
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
The general operating permit for your vehicle
could be rendered invalid if you carry out mod-
ifications to electronic components, their soft-
ware as well as wiring.
GWARNING
Gases and fluids from substances that con-
stitute a health hazard or react aggressively
can escape even from securely closed con-
tainers. When transporting such substances
in the vehicle interior, your ability to concen-
trate or your health could be affected during
the journey. Malfunctions, short circuits or
electrical component system failures may
also result. There is a risk of an accident and
fire.
Do not store or transport any substances in
the vehicle interior which are hazardous to
health or react aggressively.
These instructions must also be observed for
vehicles where the cargo compartment is not
fully separated from the driver's cab.
Partition with door/window: always keep the
door/window in the partition closed during
transport.
Examples of substances that are hazardous to
health and/or react aggressively:
RSolvents
RFuel
ROil and grease
RCleaning agents
RAcids
Protection of the environment
Economic and environmentally aware
driving
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that 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.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
Roperating conditions of your vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Introduction29
Z

When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
Have the vehicle checked and repaired immedi-
ately at a qualified specialist workshop. If you
become aware when continuing the journey that
driving safety has been effected, stop as soon as
possible in accordance with the traffic condi-
tions. In such cases, consult a qualified special- ist workshop.

accept any interference received, including
interference that may cause undesired opera-
tion of the device".
Diagnostics connection
The diagnostics connection is only intended for the connection of diagnostic equipment at a
qualified specialist workshop.
GWARNING
If you connect equipment to a diagnostics
connection in the vehicle, it may affect the
operation of vehicle systems. As a result, the
operating safety of the vehicle could be affec-
ted. There is a risk of an accident.
Only connect equipment to a diagnostics con-
nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz.
Changing the engine power output
!
Increases in engine power can:
Rchange the emission values
Rcause malfunctions
Rcause consequential damage
The operating reliability of the engine is not
guaranteed in all cases.
Any tampering with the engine management
system in order to increase the engine power
output will lead to the loss of the New Vehicle
Limited Warranty and other warranty entitle-
ments.
If you sell the vehicle, inform the purchaser
about the changes to the engine power output of
the vehicle. If you do not inform the buyer, this
may constitute a punishable offense under
national legislation.
Qualified specialist workshops
A Mercedes-Benz Commercial Van Center is a
qualified specialist workshop.
A qualified specialist workshop has the neces-
sary specialist knowledge, tools and qualifica-
tions to correctly carry out the work required on
the vehicle.
This is especially the case for work relevant to
safety. Observe the notes in the Maintenance or
Service Booklet.
The following work should always be carried out at qualified specialist workshop:
Rwork relevant to safety
Rservice and maintenance work
Rrepair work
Rmodifications as well as installations and
alterations
Rwork on electronic components
Mercedes-Benz recommends that you use a
Mercedes-Benz Commercial Van Center.
!Only have work carried out on the engine
electronics and its associated parts, such as
control units, sensors, actuating components
and connector leads, at a qualified specialist
Introduction31
Z

Please observe the information concerning
Mercedes-Benz Genuine Parts (Ypage 33).
You can obtain further information from any
Mercedes-Benz Commercial Van Center.
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
Rthe modifications or installation of accesso-
ries does not affect the safety of the vehicle
We are not responsible for the final certification,
product liability or warranty claims which result
from the modifications. This applies to:
Rthe modified components, assemblies or sys-
tems
Rany resulting noncompliance with any of the
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
Even seemingly small changes to the vehicle,
such as attaching a radiator trim for winter driv-
ing, is not permitted. Do not cover up the radi-
ator. Do not use thermal mats, insect protection
covers or anything similar.
Otherwise, the values of the diagnostic system
may be affected. Some of these values are
legally prescribed and must always be correct.

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-relevant
systems, e.g. the brake system. Only use genu-
ine Mercedes-Benz parts or parts of equal qual-
ity. Only use tires, wheels and accessories that
have been specifically approved for your vehi-
cle.
Introduction33
Z

Mercedes-Benz tests genuine Mercedes-Benz
parts, conversion parts and accessories that
have been specifically approved for the type of
vehicle for:
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).
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 con-
tains the most important information on your
vehicle, e.g. the electric cable routes, in a com-
pact form.
Further information can be found at http://
www.mercedes-benz.de/qr-code.
Data stored in the vehicle
Information from electronic control
units
There are electronic control units installed in
your vehicle. Some of these are necessary for
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.
