Fuel additives
! Do not use fuel additives (with the exception
of flow improvers), since this could lead to mal-
functions or engine damage. Damage caused by
the use of such additives is not covered by the
New Vehicle Limited Warranty.
i Special fuel additives must not be added to
winter diesel (with the exception of flow improv-
ers). The cold-flow characteristics of the fuel can
be impaired by the use of such a fuel additive.
At outside temperatures of below 14 °F
(–10 °C) and for winter-grade diesel with
less resistance to low temperatures, add a
quantity of flow improver appropriate for
the outside temperature. These substanc-
es may only be mixed within the vehicle's
fuel tank.
Add the flow improver to the diesel in good
time, i.e. before the flow properties of the
diesel are affected by paraffin separation.
Malfunctions caused by paraffin separa-
tion can only be rectified by heating the en-
tire fuel system, e.g. by parking in a heated
garage.
! Do not fill the tank with gasoline. Do not mix
diesel fuel with gasoline or kerosene. The fuel
system and engine will otherwise be damaged,
which is not covered by the New Vehicle Limited
Warranty.
Adding kerosene to diesel fuel is not rec-
ommended, even at low temperatures.
Flow improvers
The effectiveness of flow improvers cannot
be guaranteed with all fuels. Observe the
mixing ratio and comply with the handling
instructions given from the flow improver
manufacturer.
You can obtain further information from
any authorized Sprinter Dealer.
DEF is the reducing agent for the exhaust
gas aftertreatment. DEF is a non-flamma-
ble, non-toxic, colorless, odorless water-
soluble liquid.
! Only use DEF in accordance with ISO
22241. The exhaust gas aftertreatment may oth-
erwise be damaged.
Observe the MB Specification for Service Prod-
ucts, Sheet 352.0.
Damages caused by the use of other reducing
agents result in the loss of New Vehicle Limited
Warranty entitlements.
! If DEF comes into contact with painted sur-
faces or aluminum surfaces, rinse the affected
areas immediately with plenty of water.
High ambient temperatures
If DEF in the reservoir heats up to over
122 °F (50 °C) over a long period of time
(e.g. due to direct sunlight), ammonia gas
vapors may be created.
G Warning
Adding gasoline lowers the flash point of the
diesel fuel. This means that the fuel becomes
more flammable.
Do not add gasoline to the diesel fuel.
Due to the highly flammable nature of fuels,
fire, naked flames and smoking are prohibit-
ed when handling them.
