! 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 ‡ (Ò11 †). The vehicle is equipped
with a DEF preheating system at the factory.
Winter operation is therefore also guaranteed
at temperatures under 12 ‡ (Ò11 †).
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.
DEF according to ISO 22241. Observe MB Specifications for Service Products, Sheet 352.0.

Service products and capacities
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.
% 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
Diesel Exhaust Fluid (DEF)
Approximately 4.7 US gal (18.0 l)
DEF consumption
For vehicles with a 4-cylinder, in-line
engine (OM 651), the DEF consumption of
the vehicle is:
as a Cargo Van/Passenger Van, approx.
R
2322 MPG (0.2 l/100 km)
as a Cab Chassis, approx. 1720 MPG
