140Driving and operatingAdBlue
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.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.
Level warnings
The AdBlue consumption is
approximately 1.5 l per 600 miles.
The consumption can be higher
depending on driving behaviour (e.g.
high load or towing).
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.
The first possible warning message
appears at an AdBlue range below
1500 miles, shows up at each start
and each 190 miles range reduction:
Top up AdBlue: Starting impossible in 1500 mi
Additionally, control indicator Y
illuminates continuously and a chime
sounds with every message pop-up.
At an AdBlue range below 380 miles,
the following warning message is being displayed, shows up at each
start and each 12 miles range
reduction:
Top up AdBlue: Starting impossible in
380 mi
Additionally, control indicator Y
flashes continuously and a chime sounds with every message pop-up.
Notice
In case of high AdBlue consumption, the Driver Information Centre may
display this warning without the
previous warning stages.
The last warning level is entered
when the AdBlue tank is empty.
Restart of the engine is not possible.
