If DEF comes into contact with a painted
or aluminum surface, wash the surface off
immediately with plenty of water.
High ambient temperatures
When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape. Ammonia vapors have a pungent
odor and are particularly irritating for your
skin, respiratory organs and eyes. This may
result in burning eyes, nose and throat, as
well as coughing and watering eyes. Do not
inhale ammonia vapors.
If DEF heats up, e.g. in direct sunlight, in the
DEF supply reservoir for some time to over
122 ‡ (50 †), ammonia vapor will develop.
Low ambient temperatures
DEF freezes at a temperature of approx-
imately 12 ‡(00F811 †). The vehicle is equipped
with a DEF preheating system at the factory.
Winter operation is therefore also guaranteed at temperatures under 12 ‡ (00F811 †).
Additives and tap water
! Do not mix DEF with any additives and do
not dilute DEF with tap water. Otherwise,
the exhaust gas aftertreatment may be
damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage that arises through the use of addi- tives or tap water will invalidate the New
Vehicle Limited Warranty.
Storage
! Containers made of aluminum, copper,
copper alloys as well as unalloyed or
galvanized steel are not suitable for storing
DEF. If stored in these types of containers, DEF could cause constituents of these met- als to dissolve and cause irreparable dam-
age to the exhaust gas aftertreatment.
Damage caused by such impurities in the
DEF will invalidate the New Vehicle Limited
Warranty. Only store DEF in containers made of high-
alloy Cr‑Ni steel or Mo‑Cr‑Ni steel in accord-
ance with DIN EN 10 088 ‑1/2/3 or plastic
containers made of polypropylene or poly-
ethylene.
Purity
! Impurities in DEF (e.g. caused by other
service products, cleaning agents, dust,
etc.) result in increased emissions, mal-
functions, catalytic converter damage or
engine damage.
The purity of DEF is essential to prevent mal-
functions in the exhaust gas aftertreatment.
If DEF is pumped out of the DEF tank, e.g.
during repair work, the same liquid must not
be used to refill the tank. Its purity is no longer guaranteed.
Disposal
Observe country-specific laws and regula-
tions when disposing of DEF.
003D Environmental note
Dispose of DEF in an environmentally respon- sible manner.
DEF supply reservoir content
Depending on equipment, the DEF supply res-
ervoir content may vary. Tank contents

DEF consumption
For vehicles with a 4-cylinder, in-line
engine (OM 651), the DEF consumption of
the vehicle is:
R as a Cargo Van/Passenger Van, approx.
2322 MPG (0.2 l/100 km)
R as a Cab Chassis, approx. 1720 MPG
(0.35 l/100 km)
12 DEF according to ISO 22241. Observe MB Specifications for Service Products, Sheet 352.0. Service products and capacities
321Technical data Z
For vehicles with a 6-cylinder, in-line
engine (OM 642), the DEF consumption of
the vehicle is:
R as a Cargo Van/Passenger Van, approx.
2322 MPG (0.10 l/100 km)
R as a Cab Chassis approx. 1720 MPG
(0.14 l/100 km)
In each case, the stated consumption figure is a mean value between urban and extra-urban
driving cycles. The consumption figure does
not refer to a specific vehicle, but is provided for the purposes of comparison between dif-
ferent vehicle types.
DEF consumption, 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 Spec-
ifications for Service Products and the pre- scribed ACEA and/or API classifications.
Using engine oils of another quality is not
permitted and may invalidate the New Vehi-
cle 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 Specifi-
cations for Service Products. The MB Specifications for Service Products
are valid for your vehicle 13
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 tempera-
ture range in which you are operating the
vehicle, it must be changed in good time, in
particular before the cold season commen- ces. 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 signifi-
cantly 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.
13 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). 322
