Driving and operating
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
x
) from the exhaust and turns it
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.

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.
Notice
Frozen and again liquefied AdBlue is
usable without quality loss.
The typical AdBlue consumption is
approx. 2 l per 600 miles, but can also
be higher 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 warning level is entered
when the estimated AdBlue range
is between 1500 miles and
500 miles.
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
when the estimated AdBlue range
is below 500 miles. The message
with the current range will always
be displayed when ignition is
switched on. Additionally, control
indicator
B
will flash and a
chime will sound. Refill AdBlue
before entering the next warning
level.
3. The next warning level is entered
with a range below 60 miles. The
message with the current range
will always be displayed when
ignition is switched on.
Additionally, control indicator
B
will flash and a chime will
sound. Refill AdBlue as soon as
