Important safety notes
G
WARNING
Fuel is highly flammable. Improper handing 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
without delay.
R If fuel is swallowed, seek medical
assistance without delay. Do not induce
vomiting.
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
gasoline will cause damage to the fuel
system and engine.
! Do not switch on the ignition if you
accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel lines.
Notify a qualified specialist workshop and
have the fuel tank and fuel lines drained
completely.
! 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 preven tmalfunctions in the fuel
system due to contaminate dfuel.

can be found in the "Technical data" section
(Y page 317). Refueling procedure142

door when viewed in the direction of travel. It
is only possible to open the fuel filler flap
when the fron tdoor is open.
X Remove the key from the ignition lock.
X Switch off the auxiliary heating system
(Y page 118).
X Open the front left-hand door first, and then
the fuel filler flap.
X Close all vehicle doors to prevent fuel
vapors from entering the vehicle.
X Turn fuel filler cap 0006counter-clockwise,
remove it and let it hang from strap 0005.
X Completely insert the filler neck of the fuel
pump nozzle into the tank and refuel.
X Only fill the tank until the pump nozzle
switches off. Fuel may otherwise leak out.
X Replace tank filler cap 0006and turn
clockwise.
You will hear a click when the fuel filler cap
is closed fully.
X Open the front left-hand door first, and then
close the filler flap. Problems with the fuel and fuel tank
If your vehicle is losing fuel, the fuel lines or
the fuel tank are defective.
X Turn the key to position 0in the ignition
lock immediately and remove it.
X Do not restart the engine under any
circumstances.
X Consult a qualified specialist workshop. Diesel Exhaust Fluid (DEF)
Important safety notes H
Environmental note
Dispose of DEF in an environmentally
responsible manner.
! Only use DEF in accordance with
ISO 22241. Never mix DEF with additives or thin it with tap water. The exhaust gas
aftertreatmen
tmay otherwise be
damaged.
Observe the MB Specifications for Service
Products, Sheet 352.0.
Damage that results from the use of
additives or tap wate rleads 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.
! DEFi s 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 aftertreatmentr equires 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
coughing and watering of the eyes.
Do not inhale ammonia vapors. Avoid contact
with DEF.
Do not allow DEF to come intod irectcontact
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 DEFr eserve has fallen 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 178). Refueling

Service products include the following:
R Fuels, e.g. diesel
R Additives for the exhaus tgas
aftertreatment, e.g .Diesel Exhaust Fluid
(DEF)
R Lubricants, e.g. engine oil, transmission oil
R Coolant
R Brake fluid
R Washer fluid
R Climate control system refrigerants
Approved service products comply with the
highes tquality standards and are listed in the
MB Specifications for Service Products. Only
use service products approved for the
vehicle. This is an important condition for the
warranty.
You will recognize the approved service
products by the inscription on the container:
MB Approval (e.g. MB Approval 228.5)
Other identifications and recommendations
refer to quality level or a specification
according to an MB Sheet Number (e.g. MB
228.5). They are therefore not necessarily
approved.
Further information can be obtained at any
qualified specialist workshop.
Additives for approved service products are
neither required no rpermitted. Approved fuel
additives are the exception .Additives can
cause engine damage and must therefore not
be added to the service products.
The use of additives is always the
responsibility of the vehicle operator .The use
of additives may result in the restriction or
loss of your Limited Warranty entitlements. Fuel

d(DEF)
General notes !
Only use DEF in accordance with
ISO 22241. The exhaus tgas aftertreatment
system may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage caused by the use of other
reducing agents will invalidat ethe New
Vehicle Limited Warranty.
! 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 in the DEF reservoir heats up to
temperatures above 122 ‡
(50†) foralong
period of time (e.g. due to direct sunlight),
ammonia vapors form.
Low ambient temperatures DEF freezes at a temperature of
approximately 12
‡(002711 †). The vehicle is
equipped with a DEF preheating system at the
factory .This ensures that the vehicle can be
operated in winter, even at temperatures
below 12 ‡(002711 †).
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
additives or tap water will invalidate the
New Vehicle Limited Warranty.
Storage !
Containers made of aluminum, copper,
coppe ralloys as well as unalloyed or
galvanized steel are not suitable for storing
DEF. If stored in these types of containers,
DE Fc ould cause constituents of these
metals to dissolve and cause irreparable
damage to the exhaust gas aftertreatment.
Damage caused by such impurities in the
DEFw ill invalidate the New Vehicle Limited
Warranty.
Only store DEF in containers made of high-
alloy Cr-Ni steel or Mo-Cr-Ni steel in
accordance with DIN EN 10 088-1/2/3 or
plastic containers made of polypropylene or
polyethylene.
Purity !
Impurities in DE F(e.g. caused by other
service products, cleaning agents, dust,
etc.) result in increased emissions,
malfunctions, catalytic converter damage
or engine damage.
The purity of DEFi s essential to prevent
malfunctions 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
regulations when disposing of DEF.
