AdBlue® is a very stable product with a long
shelf life. Stored at temperatures LOWER than
90°F (32°C), it has a shelf life of at least one
year. For more information on the AdBlue®
liquid type

page 424. The vehicle is equipped
with an automatic AdBlue® heating system
when the engine starts, allowing the system to
work correctly at temperatures lower than 12°F
(-11°C).
NOTE:
AdBlue® freezes at temperatures lower than
12°F (-11°C).
AdBlue® (UREA) Storage
AdBlue® (UREA) is considered a very stable product
with a long shelf life. If AdBlue® (UREA) is kept in
temperatures between 10° and 90°F (-12° and
32°C), it will last a minimum of one year.
AdBlue® (UREA) is subject to freezing at the
lowest temperatures. For example, AdBlue®
(UREA) may freeze at temperatures at or below
12°F (-11°C). The system has been designed to
operate in this environment.
NOTE:
When working with AdBlue® (UREA), it is
important to know that:

Any containers or parts that come into
contact with AdBlue® (UREA) must be
AdBlue® (UREA) compatible (plastic or stain-
less steel). Copper, brass, aluminum, iron or
non-stainless steel should be avoided as they
are subject to corrosion by AdBlue® (UREA).

If AdBlue® (UREA) is spilled, it should be
wiped up completely.
CAUTION!
For diesel engines, only use diesel fuel for
motor vehicles in accordance with EN 590
European specifications. The use of other
products or mixtures may damage the engine
beyond repair and consequently void the
warranty, due to the damage caused. If you
accidentally introduce other types of fuel into
the tank, do not start the engine. Empty the
tank. If the engine has been run for even an
extremely limited amount of time, you must
not only drain the fuel tank, but the rest of the
supply circuit as well.
