Do not blend other fuel additives with fuel.
This only results in unnecessary cost and may
be harmful to the engine operation.
!
Damage or malfunction resulting from
poor fuel quality or from blending additional
fuel additives other than those tested and
approved by us for use on Mercedes-Benz
vehicles are not covered by the Mercedes-
Benz Limited Warranty or by any pre-owned
or Extended Limited warranties.
AdBlue
®
AdBlue
®
is a non-flammable, non-toxic,
colorless and odorless, water-soluble liquid.
!
Only use AdBlue
®
complying with
ISO 22241. Do not blend with additives.
!
Rinse surfaces that have come into
contact with AdBlue
®
, or remove AdBlue
®
with a moist cloth and cold water
immediately. If AdBlue
®
has crystallized
already, use cold water and a sponge.
AdBlue
®
residues will crystallize and soil
the affected surfaces.
High ambient temperatures
If AdBlue
®
in the reservoir heats up to above
122‡ (50†) for a long period of time, for
example due to direct sunlight, ammonia gas
vapors may escape when opening the
AdBlue
®
tank.
G
Warning!
When opening the filler cap of the
AdBlue
®
tank ammonia gas vapors may
escape. Refill AdBlue
®
in a well ventilated
area only. Ammonia gas vapors have a
pungent odor and are particularly irritating
for your skin, mucous membranes, and
eyes. Inhaling ammonia gas vapors will
cause burning eyes, nose, and throat, as
well as coughing and watering eyes.
Low ambient temperatures
AdBlue
®
freezes at a temperature of
approximately 12‡ (-11†). Your vehicle is
factory equipped with an AdBlue
®
preheating
system. The vehicle can thus be operated at
temperatures below 12‡ (-11†).
Special additives
!
Only use AdBlue
®
complying with
ISO 22241. Do not add additives to
AdBlue
®
and do not dilute AdBlue
®
with
water. Otherwise, the BlueTEC exhaust gas
aftertreatment system could be damaged.
Damage caused by using additives or
diluting with water are not covered by the
Mercedes-Benz Limited Warranty.
Purity
The purity of AdBlue
®
is of particular
importance for avoiding malfunctions in the
exhaust gas aftertreatment.
If AdBlue
®
is pumped out of the tank, e.g.
during repair work, the same liquid must not
be used to refill the tank as its purity is no
longer guaranteed.
!
Impurities caused for example by other
service products, cleaning agents, and dust
result in increased emissions,
malfunctions, catalyst damage, or engine
damage.
