Important safety notes
G
WARNING
Fuel is highly flammable. Improper handling
of fuel creates a risk of fire and explosion.
Avoid fire, open flames, smoking and creating
sparks under all circumstances. Switch off the
engine and, if applicable, the auxiliary heating
before refueling. G
WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
R If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
R Immediately change out of clothing which
has come into contact with fuel. G
WARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline
with diesel fuel. H
Environmental note
If fuels are handled improperly, they pose a
danger to persons and the environment. Do
not allow fuels to run into the sewage system,
the surface waters, the ground water or into
the ground.
! Do not use gasoline to refuel vehicles with
a diesel engine. Even small amounts of gas-
oline will cause damage to the fuel system
and engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
a qualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Filter the fuel before transferring it to the
vehicle if you are refueling the vehicle from
barrels or containers.
This will prevent malfunctions in the fuel
system due to contaminated fuel.

Important safety notes H
Environmental note
Dispose of DEF in an environmentally respon-
sible manner.
! Only use DEF in accordance with
ISO 22241. Never mix DEF with additives or thin it with tap water. The exhaust gas
aftertreatment may otherwise be dam-
aged.
Observe the MB Specifications for Service
Products, Sheet 352.0.
Damage that results from the use of addi-
tives or tap water leads to the loss of the
New Vehicle Limited Warranty.
! If DEF comes into contact with a painted
or aluminum surface, wash the surface off
immediately with plenty of water.
! DEF is not a diesel additive and must not
be mixed with fuel in the tank. Even small
amounts of DEF can cause engine damage.
Damage that results from the blending of
DEF will not be covered by the New Vehicle
Limited Warranty.
The exhaust gas aftertreatment requires a
reducing agent, Diesel Exhaust Fluid (DEF), in
order to function correctly.
When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape.
Ammonia vapors have a pungent smell and
primarily cause irritation of the:
R skin
R mucous membranes
R eyes
You may experience a burning sensation in
your eyes, nose and throat, as well as cough-
ing and watering of the eyes.
Do not inhale ammonia vapors. Avoid contact
with DEF.
Do not allow DEF to come into direct contact
with your skin; it is hazardous to your health.
Rinse any affected areas off with plenty of
clean water. Consult a doctor if necessary.
i If the DEF level has dropped below the
reserve range, add at least 2.0 US gal
(7.6 l) of DEF at the latest after receiving
the second warning message
(Y page 184). Refueling
