as soon as the self-cleaning
operation is complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 178, 3 241 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 designation of this fluid is AdBlue Ⓡ 1)
. 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.
4000 mpg and depends on the driving
behaviour.
If the AdBlue level falls below a
certain value, a level warning AdBlue
Range: 1500 mi will be displayed in
the Driver Information Centre.
A volume of at least 5 litres of AdBlue must be refilled as soon as possible.
Driving is possible without any
restrictions.

Diesel-engined vehicles have special
fuel filler caps.
Fuel consumption - CO 2-
Emissions
The fuel consumption (combined) is
within a range of 39 to 54 mpg.
The CO 2 emission (combined) is
within a range of 172 to 138 g/km.
For the values specific to your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle or other national registration
documents.
General information
The official fuel consumption and
specific CO 2 emission figures quoted
relate to the EU base model with
standard equipment.
Fuel consumption data and CO 2
emission data are determined
according to regulation
R (EC) No. 715/2007 (in the latestapplicable version), taking into
consideration the vehicle weight in running order, as specified by the
regulation.
The figures are provided only for the purpose of comparison between different vehicle variants and mustnot be taken as a guarantee for the
actual fuel consumption of a
particular vehicle. Additional
equipment may result in slightly
higher results than the stated
consumption and CO 2 figures.
Furthermore, fuel consumption is
dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
The bulb outage detection function for
trailer brake light cannot detect a
partial bulb outage, e.g. in case of 4 x
5 Watt bulbs, the function only detects lamp outage when only a single
5 Watt lamp remains or none remain.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball
bar for towing. Always keep the
coupling ball bar in the vehicle.
