Checking and refilling levels
We recommend the use of die
sel
f
uel which
complies to European standard EN 590. If
diesel fuel which meets European standard
EN 590 is not available, the Cetane number
(CZ) must, at minimum, be 51. If the engine
is equipped with a particulate filter, the sul-
phur content of the fuel must be below 50
parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it
is more difficult to start the engine. For this
reason, petrol stations in some countries al-
so offer winter diesel with improved fluidity
when cold (winter-grade diesel).
Water in the fuel filter
1)
If your vehicle has a diesel engine and is
equipped with a fuel filter with a water sepa-
rator, the instrument panel may display the
following warning:
Water in the
fuel filter. If this is the case, take the
vehicle to a specialised workshop so that
they can drain the fuel filter.
CAUTION
●
The vehic
le is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
●
Do not mix
fuel additives, the so-called
“thinners”, petrol or similar additives with
diesel fuel.
●
If poor-quality diesel fuel is used, it may be
necessary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done
by a specialised workshop. If water is allowed
to collect in the filter, this can cause engine
performance problems.

Inf
orm
ation on AdBlue

The consumption of AdBlue
®
depend
s
on
y
our personal driving style, the temperature
of the system and on the outdoor tempera-
ture when the vehicle is used.
AdBlue
®
freezes at temperatures of -11°C
(+13°F). The system has heating elements
that guarantee its operation even at low tem-
peratures.
The AdBlue
®
tank level capacity is approxi-
mately 11 litres.
The AdBlue
®
tank should never be empty.
When the distance to empty drops below
2400 km, a warning to refill the AdBlue
®
tank
will appear on the dash panel display
››› page 283. If this information is ignored, it
will later no longer be possible to re-start the
engine. If this warning does not appear, it is
not necessary to refill the AdBlue
®
tank.
AdBlue

is a registered brand of the German
Association of the Automotive Industry (VDA)
and is also known as AUS32 or DEF (Diesel
Exhaust Fluid).
CAUTION
Filling the AdBlue
®
tank e
xcessively can
cause damage to the tank.
