ual message is shown in the multifunction
display. Awarning tone also sounds.
If the Refill AdBlue No start in: .. km message is shown in the multifunction dis-

sequently be unable to start the engine.
After receiving the warning message, it is
preferable to fill the AdBlue ®
tank with
10 litres of AdBlue ®
.Int his way, you can
ensure that the AdBlue ®
supply lasts until the
next regular service date.
Further information about BlueTEC exhaust
gas aftertreatment and about AdBlue ®
can
be obtained from any Mercedes-Ben zService
Centre.
Topping up AdBlue ®!
Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
, and do not dilute AdBlue ®
with
water. This may destroy the BlueTEC
exhaust gas aftertreatmen tsystem.
! In order to fill the AdBlue ®
tank, the vehi-
cle mus tbe parked on a level surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on a level surface.
Fluctuations in capacity will thus be avoi-
ded. Filling a vehicle standing on an uneven
surface is not permitted. There is a danger
of overfilling, which can cause damage to
BlueTEC exhaust gas aftertreatmen tcom-
ponents. !
Do not fill the AdBlue ®
container with a
pump nozzle.
! If there are steep gradients while driving
off-road, a sufficient filling level in the
AdBlue ®
tank must be ensured. Make sure
for this reason that there is a minimum fill
level of ten litres before driving off-road.
! Surfaces which have come into contact
with AdBlue ®
while refilling should be
rinsed immediately with water, or remove
AdBlue ®
with a moist cloth and cold water.
If AdBlue ®
has already crystallised, use a
sponge and cold water to clean the area.
AdBlue ®
residue crystallises after a certain
amount of time and soils the affected sur-
faces.
! AdBlue ®
is not a fuel additive and must
not be added to the fuel tank.IfA dBlue®
is
added to the fuel tank, this can lead to
engine damage.
If you open the AdBlue ®
tank cap, small
amounts of ammonia vapour may be
released.
Ammonia vapours have a pungen todour and
are particularly irritating to:
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.
