AdBlue

General information
The selective catalytic reduction
(BlueInjection) is a method to
substantially reduce the nitrogen
oxides in the exhaust emission. This
is achieved by injecting a Diesel
Exhaust Fluid (DEF) into the exhaust
system. The ammonia released by
the fluid reacts with nitrous gases
(NO ) from the exhaust and turns it
x
into nitrogen and water.
The designation of this fluid is
AdBlue ® . It is a non-toxic, non-
flammable, colourless and odourless
fluid which consists of 32% urea and
68% water.
9 Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
Caution
Avoid contact of the paintwork with
AdBlue.
In case of contact, rinse off with
water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue pre-heater,
the emissions reduction at low
temperatures is ensured. The AdBlue
pre-heater works automatically.
Note
Frozen and again liquefied AdBlue is
usable without quality loss.
The typical AdBlue consumption is
approx. 22 l per 10000 km to
15000 km depending on driving
behaviour (e.g. high load or towing).
Level warnings
Depending on the calculated range of
AdBlue, different messages are
displayed in the Driver Information
Centre. The messages and the
restrictions are a legal requirement.
1. The first possible warning is Top
up emissions additive: Starting
prevented in 2400 km.
When switching on the ignition,
this warning will show up once
briefly with the calculated range.
Additionally, control indicator
B will illuminate and a chime
will sound. Driving is possible
without any restrictions.
2. The next warning level is entered
with a range below 800 km. The
message with the current range
will always be displayed when
ignition is switched on.
Additionally, control indicator
B will illuminate and a chime
will sound. Refill AdBlue before
entering the next warning level.
When driving, the chime sounds
and the message is displayed
every 100 km until the AdBlue
tank has been topped-up.
3. The next warning level is entered
with a range below 100 km. The
message with the current range
will always be displayed when
ignition is switched on.
Additionally, control indicator
