AdBlue is a non-flammable, non-toxic,
colorless, odorless and water-soluble fluid.
! Only use AdBlue
ISO 22241. Do not add any special
additives to AdBlue
®
AdBlue with water. This could destroy the
BlueTEC exhaust gas aftertreatment.
! Rinse surfaces that have come into
contact with AdBlue
water or remove AdBlue
cloth and cold water. If the AdBlue
already crystallized, use a sponge and cold
water to clean it. AdBlue

affected surfaces.
High outside temperatures
®
If AdBlue is heated to above 122 ‡ (50 †)
for an extended period of time, e.g. due to
direct sunlight on the AdBlue
®
AdBlue may start to decompose. Ammonia
vapors develop as a result.
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 outside temperatures
®
AdBlue freezes at a temperature of
approximately 12 ‡(11 †). The vehicle is
equipped with an AdBlue
at the factory. Winter operation can thus be
guaranteed even at temperatures below
12 ‡(–11 †).
