Driving and operating143Caution
Fuel grades other than those listedon pages 3 169, 3 230 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 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.
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.
The typical AdBlue consumption is
approx. 2 l per 1000 km , but can also
be higher depending on driving
behaviour (e.g. high load or towing).
AdBlue tank The AdBlue tank level can be found in the display menu.
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.
144Driving and operatingThe 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 96. 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.
3 235
High emission warnings
If the exhaust emission rises above a certain value, warnings similar to the
range warnings will be displayed in
the Driver Information Centre.
Requests to have the exhaust system checked and finally the
announcement of the prevention ofan engine restart are displayed.
These restrictions are a legal
requirement.
Consult a workshop for assistance.
Refilling AdBlueCaution
Only use AdBlue that complies
with European standards
DIN 70 070 and ISO 22241-1.
Do not use additives.
Do not dilute AdBlue.
Otherwise the selective catalytic
reduction system could be
damaged.
Note
Whenever a filling pump with a
nozzle for passenger cars is not
available at a filling station, use only
AdBlue bottles or canisters with a
sealed refill adapter for refilling, to
prevent splashback and overspill,
and in order to ensure that the fumes
from the tank are captured and do
not emerge. AdBlue in bottles or
canisters is available in many filling
