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 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.
AdBlue gauge
In versions without AdBlue level
warnings in the Driver Information
Centre, an AdBlue gauge is present,
which shows the current AdBlue fluid
level remaining in the tank.
AdBlue gauge 3 89.
Level warnings
The AdBlue consumption is approx.
3.5 litres per 600 miles (810 mpg) and depends on the driving behaviour.
Version with level warnings in the
Driver Information Centre
If the AdBlue level falls below a
certain value, a level warning will be
displayed in the Driver Information
Centre 3 100.
142Driving and operating
Additionally, control indicator Õ
illuminates continuously together with a warning chime.
Refill the AdBlue tank as soon as
possible. Refer to "Refilling AdBlue"
below.
If AdBlue is not refilled within a certain
distance, further level warnings are
displayed in the Driver Information
Centre depending on the current
AdBlue level.
Engine restarts prevented
Subsequent requests to refill AdBlue
and finally the announcement that an engine restart will be prevented are
displayed in the Driver Information
Centre.Notice
These restrictions are a legal
requirement.
Before the prevention of an engine
restart, a warning message with
0 miles is displayed in the Driver
Information Centre, indicating that after switching off the ignition an
engine restart will be prohibited.
After the prevention of an engine
start, a warning message is displayed in the Driver Information Centre
reminding the driver that AdBlue level
is insufficient.
To allow the engine to be restarted,
the tank should be refilled completely
or with a volume of at least ten litres
of AdBlue, depending on AdBlue
consumption.Warning stages: level warnings,
engine restarts prevented 1. Y illuminates after the ignition is
switched on with warning
message LEVEL ADBLUE LOW :
Driving is possible without any
restrictions.
Refill the AdBlue tank as soon as
possible.2. Y illuminates during driving with

ADBLUE :
Possible loss of engine power.
Refill the AdBlue tank as soon as
possible.
3. Y illuminates during driving with
warning message XXX KM STOP
ADD ADBLUE :
Vehicle speed may be limited to
12 mph after switching the engine off and on again until the range is
reduced to 0 miles.
Refill the tank completely or with a
volume of at least ten litres of
AdBlue (depending on AdBlue
consumption) as soon as
possible.
4. Y illuminates during driving with
warning message 0 KM STOP
ADD ADBLUE :
The engine cannot be restarted
after switching off the ignition.
To allow the engine to be
restarted, refill the tank
