14DEF consumption
Depending on the vehicle version, the DEF
consumption is:
R for the Cargo Van/Passenger Van,
approximately 2322 MPG (0.10 l/100 km)
R for the Cab Chassis, approximately
1720 MPG (0.14 l/100 km)
In each case, the stated consumption figure
is a mea nvalue between urban and extra-
urban driving cycles. The consumption figure
does no trefer to a specific vehicle, but is
provided for the purposes of comparison
between differen tvehicle types.
DEFc onsumption, like fuel consumption, is
very dependent on the driving style and the
operating conditions. This means that the real
consumption figures during operation of your
vehicle may deviate from those stated. Engine oil
General notes !
The bottles of the various engine oil types
are marked with ACEA (Association des
Constructeurs Européens d'Automobiles)
and/or API (American Petroleum Institute)
classifications. Only use approved engine
oils that conform to the following MB Specifications for Service Products and the
prescribed ACEA and/or API
classifications. Using engine oils of another
quality is not permitted and may invalidate
the New Vehicle Limited Warranty.
The use of other, non-approved engine oils
for diesel engines can cause damage to the
diesel particle filter (DPF).
Use only engine oils that have been approved
for your vehicle according to the MB
Specifications for Service Products.
The MB Specifications for Service Products
are valid for your vehicle 15
R 228.51
R 229.31
R 229.51
These are high quality engine oils which have
a positive effect on:
R engine wear
R fuel consumption
R exhaust gas emissions.
Multi-grade engine oils of the prescribed SAE
class (viscosity) may be used all year round,
taking the outside temperatures into
account.
Engine oil viscosity !
If the SAE viscosity class of the engine oil
used does not cover the outside
temperature range in which you are
operating the vehicle, it must be changed
in good time, in particular before the cold
season commences. Using an engine oil
that does not have adequate temperature
characteristics can lead to engine damage.
The temperature range information of the
SAE classification always refers to that of
fresh oil. The temperature characteristics
of the engine oil may deteriorate

15 If the quality grade is not available for diesel, you may also add engine oils meeting the requirements in MB
Sheet No. 228.5, 229.3 or 229.5. The quantity to be added is then limited to a maximum of 1 qt (1 l). Service products and capacities

significantly due to aging in use, especially
at low outside temperatures.
We recommend that you change the engine
oil before the cold season commences. Use
an approved engine oil of the specified SAE
class.
Engine oil SAE classification
Viscosity indicates the flow characteristics of
a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Depending on the respective outside
temperatures, select an engine oil according
to SAE classification (viscosity). The table
displays the SAE classification to be used.
The low temperature characteristics of
engine oils can noticeably deteriorate during
operation, e.g. from aging, soot and fuel
accretion. For this reason, regularo il changes
using an approved engine oil fro mthe suitable
SAE classification are urgently
recommended.
Additives !
Do not use any additives in the engine oil.
This could damage the engine.
Miscibility of engine oils !
Mixing oils reduces the benefits of using
high grade engine oils.
We recommend that you only add engine oil
of the same quality grade and SAE class as
used when the engine oil was last changed. If, in exceptional cases, oil of the type in the
engine is not available, top up using another
approved mineral or synthetic engine oil.
If the quality grade is not available for diesel
engines, you may also add engine oils
meeting the requirements in MB Sheet
Number 228.5, 229.3 or 229.5. The quantity
to be added is then limited to a maximum of
1 qt (1 l).
Engine oils are differentiated according to:
R
engine oil brand
R quality grade (sheet number)
R SAE class (viscosity)
Subsequently have the engine oil changed at
the earliest possible opportunity.
Interval for oil change Oil change intervals depend on the vehicle's
operating conditions and the quality of the
engine oil used. The on-board computer
automatically shows the date for the next oil
change as an event message in the display.
Only by using engine oil with a particularly
high quality grade, e.g. according to Sheet
Number 228.51 of the Mercedes-Benz
Specifications for Service Products, can the
maximum interval for oil change be achieved.
We recommend having the oil changed at a
qualified specialist workshop.

Take care not to spill any coolant on
painted surfaces. You could otherwise
damage the paintwork.
Coolant additive with corrosion/
antifreeze protection !
Use only approved antifreeze/corrosion
inhibitor that complies with MB
Specification for Service Products, Sheet
Number 325. Using other, non-approved
antifreeze/corrosion inhibitors may cause
damage to the coolant system and reduce
the engine's service life.
Coolant is a mixture of water and antifreeze/
corrosion inhibitor. It performs the following
tasks:
R corrosion protection
R antifreeze protection
R raises the boiling point
When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection. Coolant
must be used in the system all yearr ound to
ensure anti-corrosion protection and a raised
boiling point –even in countries with high
outside temperatures.
To prevent damage to the engine cooling
system, use only approved corrosion
inhibitor/antifreeze that comply with the
Mercedes-Benz Specifications for Service
Products. You will find information about
approved corrosio ninhibitor/antifreeze for
your vehicle in the Maintenance Booklet.
We recommend corrosion inhibitor/
antifreeze tha tmeets the requirements in MB
Specifications for Service Products Sheet
Number 325.
Check the antifreeze/corrosion inhibitor
concentration in the coolant every six
months. The percentage of corrosion inhibitor/
antifreeze additive in the engine cooling
system should:
R
be at least 50%. This way, the engine
cooling system is protected against
freezing down to approximately -35 ‡
(-37 †).
R not exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
If there has been coolant loss, do not refill
only with water. If the vehicle has lost coolant,
add equal parts water and corrosion
inhibitor/antifreeze additive. The water used
as part of the coolant mixture must fulfill
certain requirements; these are usually
fulfilled by drinking water. If the water quality
is not sufficient, you must treat the water.
Further information can be obtained at any
qualified specialist workshop.
