Driving and operating169Caution
If possible, do not interrupt
cleaning process. Drive until
cleaning is completed to avoid the need for service or repair by a
workshop.
Cleaning process not possible
If cleaning is not possible for anyreasons, control indicator Z
illuminates and a warning message
appears in the Driver Information
Centre. Engine power may be
reduced. Seek the assistance of a
workshop immediately.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 221, 3 289 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
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.9Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
170Driving and operatingCaution
Avoid contact of the paintwork withAdBlue.
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.
The typical AdBlue consumption is
approx. two litres per 1000 km, but
can also be higher depending on
driving behaviour (e.g. high load or
towing).
AdBlue tank
At a remaining volume of approx. five litres, there is a liquid level switch. Warning messages are displayed
only below that threshold. Tank
volume 3 296.
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.
The first possible warning is AdBlue
Range: 2400 km .
This warning will show up once briefly with the calculated range. Driving is
possible without any restrictions.
The next warning level is entered with
a range below 1750 km. The
message with the current range will always be displayed when ignition is
switched on and needs to be
confirmed 3 116 . Refill AdBlue before
entering the next warning level.
At an AdBlue range below 900 km,
the following warning messages are
alternately displayed and cannot be
dismissed:
● AdBlue Low Refill Now
● Engine Restart Prevented in 900
km .
Additionally, control indicator Y
flashes continuously.Note
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.
The following warning messages are
alternately displayed and cannot be
dismissed:
● AdBlue Empty Refill Now
● Engine Will Not Restart .
Additionally, control indicator Y
flashes continuously.
With active prevention of an engine
start, the following message will be
displayed:
Refill AdBlue To Start Vehicle .
The tank must be refilled completely
with AdBlue, otherwise restarting of the engine is not possible.
