General notes
To function properly, BlueTEC exhaust gas after-
treatment must be operated with the reducing
agent AdBlue
®
.
When the supply of AdBlue
®
is almost used up,
the
Refill AdBlue See Owner's Manual
Refill AdBlue See Owner's Manual
message is shown in the multifunction display. A
warning tone also sounds.
If the
Refill AdBlue No start in X km
Refill AdBlue No start in X km
message is shown in the multifunction display,
you can still drive the vehicle over the distance
shown. If AdBlue
®
is not topped up, you will
subsequently be unable to start the engine.
When you see the warning message, it is rec-
ommended that you fill the AdBlue
®
reservoir
with 10 litres of AdBlue
®
. This ensures that the
AdBlue
®
supply will last until the next regular
service due date.
Further information about BlueTEC exhaust gas
aftertreatment and about AdBlue
®
can
be obtained from any Mercedes-Benz Service
Centre.
i
You can also have the AdBlue
®
tank refilled
at a qualified specialist workshop.
If the outside temperature is lower than
Ò
11 †,
it may be difficult to top up. If AdBlue
®
is frozen
and there is an active warning indicator, topping
up may not be possible. Park the vehicle in a
warm place, e.g. in a garage, until AdBlue
®
has
become liquid again. Topping up is then possible
again. Alternatively, have the AdBlue
®
tank refil-
led at a qualified specialist workshop.
Before driving your vehicle outside Europe, have
the AdBlue
®
supply checked at a qualified spe-
cialist workshop.

Important safety notes
AdBlue
®
is a water-soluble fluid for the exhaust
gas aftertreatment of diesel 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 a pungent odour and are
particularly irritating to the skin, mucous mem-
branes and eyes. You may experience a burning
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. Fill the AdBlue
®
tank only in well-ven-
tilated areas.
Do not swallow AdBlue
®
or let it come into con-
tact with skin, eyes or clothing. Keep AdBlue
®
away from 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
®
, and do not dilute AdBlue
®
with
water. This may destroy the BlueTEC exhaust
gas aftertreatment system.
!
In order to fill the AdBlue
®
tank, the vehicle
must be 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 avoided.
Filling a vehicle standing on an uneven sur-
face is not permitted. There is a danger of
overfilling, which can cause damage to Blue-
TEC exhaust gas aftertreatment components.
!
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 surfaces.
!
AdBlue
®
is not a fuel additive and must not
be added to the fuel tank. If AdBlue
®
is added
