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
Diesel Exhaust Fluid (DEF)
12 Approximately 3.2 US gal (12.0 l
13 Approximately 4.7 US gal (18.0 l
14 Approximately 4.9 US gal (18.5 l)
13 Approximately 5.8 US gal (22.0 l)
15 DEF consumption
For vehicles with a 4-cylinder, in-line
engine (OM 651), the DEF consumption of
the vehicle is:
R
as Cargo Van/Passenger Van, approx.
2322 MPG (0.2 l/100 km)
R as Cab Chassis, approximately 1720 MPG
(0.35 l/100 km)
For vehicles with a 6-cylinder, in-line
engine (OM 642), the DEF consumption of
the vehicle is:
R as Cargo Van/Passenger Van, approx.
2322 MPG (0.10 l/100 km)
R as Cab Chassis, approximately 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 pro-
vided for the purposes of comparison
between different 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.
