Important safety notes
G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is arisk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is adanger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren. If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is arisk of
fire and explosion.
Always touch the vehicle body before opening the fuel filler flap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up.
Do not get into the vehicle again during the refu-
elling process. Otherwise, electrostatic charge
could build up again. G

If you mix dieself
uel with petrol, the flash
point of this fuel mixture is lowert han that of
pure dieself uel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is arisk of fire.
Never refuel with petrol. Never add petrol to
dieself uel.
! Do not use dieseltor
efuel vehicleswith a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise ,the fuel wille nter the fuel system.
Even small amounts of the wrong fuel can
resultind amage to the fuel system and the
engine. Notify aqualifieds pecialist workshop
and have the fuel tank and fuel lines drained
completely.
! Do not use petrol to refuel vehicle
swith a
diesele ngine. Do not switch on the ignition if
you accidentally refuel with the wrong fuel.
Otherwise ,fuel can enter the fuel system.
Even small amounts of the wrong fuel could
resultind amage to the fuel system and the
engine. The repairc osts are high. Notify a
qualifieds pecialist workshop and have the
fuel tank and fuel lines drained completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spilla
ny fuel on painted
surfaces .You could otherwise damage the
paintwork.
! Use
afilter when adding fuel from afuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particle sfrom
the fuel can.
If you overfill the fuel tank, some fuel may spray
out when you remove the fuel pump nozzle.

is aw ater-solublef luid for the exhaust
gas aftertreatmentofd iesel engines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts of
ammonia vapour may be released.
Ammonia vapours have apungent odour and are
particularlyi rritating to the skin, to mucous
membranes and to the eyes. You may experi-
ence aburning sensation in your eyes, nose and
throat. You may also experience coughing and
watery eyes.
Do not inhale any ammonia vapours that may be
released.O nly fill the AdBlue ®
tank in well-ven-
tilated areas. Do not swallow AdBlue
®
or let it come into con-
tact with skin, eyes or clothing. Keep AdBlue ®
awayf rom children.
If you or others come into contact with AdBlue ®
,
observe the following:
R immediately rinse AdBlue ®
off your skin with
soap and water.
R if AdBlue ®
comes into contact with your eyes,
immediately rinse them thoroughly with clean water. Seek medical attention immediately.
R if AdBlue ®
is swallowed, immediately rinse
your mouth out thoroughly. Drink plenty of
water. Seek medical attention immediately.
R change immediately out of clothing that has
come into contact with AdBlue ®
.
! Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
,a nd do not dilute AdBlue ®
with
water. This may destroy the BlueTEC exhaust
gas aftertreatments ystem.
! In order to fill the AdBlue ®
tank, the vehicle
must be parked on alevel surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on alevel surface.
Fluctuations in capacity will thus be avoided.
Filling avehicle standing on an uneven sur-
face is not permitted. There is adanger of
overfilling, which can cause damage to Blue-
TEC exhaust gas aftertreatmentc omponents.
! Surfaces which have come into contact with
AdBlue ®
while refilling should be rinsed
immediately with water, or remove AdBlue ®
with amoist cloth and cold water. If AdBlue ®
has already crystallised,u seasponge and
cold water to clean the area. AdBlue ®
residue
crystallises after acertain amount of time and
soils the affected surfaces.
! AdBlue ®
is not afuel additive and must not
be added to the fuel tank. If AdBlue ®
is added
to the fuel tank, this can lead to engine dam-
age.
Have the AdBlue ®
tank refilled at aqualified
specialist workshop. However, you can also top
up the AdBlue ®
tank:
