WARNING
ARNING Risk of re from fuel mixture
If you mix diesel fuel with gasoline, the ash
point of the fuel mixture is lower than that of
pure diesel fuel.
#
Never refuel using gasoline in diesel
engines.
#
Never mix gasoline with diesel fuel.

TE Damage due to incorrect fuel
Even small amounts of the wrong fuel could
result in damage to the fuel system, the engine
and the emission control system.
Never refuel with the following:
R
Gasoline
R
Marine diesel
R
Heating oil
R
Pure fatty acid methyl ester or vegetable oil
R
Para n or kerosene
#
Do not mix such fuels with diesel fuel and
do not use any additive.
If you have accidentally refueled with the
wrong fuel, observe the following:
#
Do not switch the ignition on.
#
Consult a quali ed specialist workshop.

NNOOTE
TE Malfunctions due to contaminated
fuel
Fuel contamination can lead to malfunctions in
the fuel system.
#
If you are using drums or canisters to
refuel the vehicle, you should lter the
fuel before lling.
*
NNOOTE
TE Damage due to incorrect fuel
Incorrect fuel can lead to engine damage.
#
Refuel only ULSD or diesel fuel with a
sulfur content of maximum 15 ppm.
Usually you will nd information about the fuel
grade on the fuel dispenser. If there is no identi -
cation on the fuel pump, consult a gas station
attendant.
The fuel grade recommended for your vehicle is
found on the instruction label in the fuel ller ap .

WARNING
ARNING Risk of re and explosion from
igniting fuel
If you heat up parts of the fuel system, fuel
may leak and ignite. Depending on the type of
damage, fuel might not escape until the engine
is running.
#
Never heat fuel system components.
#
Contact a quali ed specialist workshop
to rectify the malfunction.
Re ll only with commercially available ULTRA-LOW
SULFUR DIESEL (ULSD, maximum sulfur content
15 ppm), which ful lls the ASTM D975 standard.
The ow properties of diesel fuel may be inade-
quate at low outside temperatures due to para n
separation.
%
Malfunctions resulting from para n separation
can only be recti ed by heating the entire fuel
system. Park the vehicle in a heated garage,
for example.
To prevent malfunctions, diesel fuel with improved
ow characteristics is available in the winter
months. You can obtain further information on this
at the gas station or from your fuel supplier.
Your vehicle is equipped with a fuel preheating sys-
tem. This additionally improves the ow character-
istics of the diesel fuel by about 14.5°F (8°C).
ULTRA-LOW SULFUR DIESEL can be used without
risk of malfunction down to an outside tempera-
ture of approximately 14.5°F (-10°C).

NNOOTE
TE Damage due to gasoline or para n
Gasoline or para n in diesel fuel impairs the
lubricity of the fuel. This can result in damage
to the fuel injection system, for example.
#
Do not add any gasoline or para n to
diesel fuel to improve its ow character-
istics.
