AdBlue
General information The selective catalytic reduction 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.
Level warnings
The AdBlue consumption is approx.
3.5 l per 600 miles (810 mpg) and
depends on the driving behaviour.
AdBlue gauge 3 93.
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 3 104.
Additionally, control indicator ú
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.
146Driving and operatingEngine 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 10 l of
AdBlue, depending on AdBlue
consumption.Warning stages: level warnings,
