A cold diesel engine makes more noise dur-
ing winter temperatures than summer tem-
peratures. Furthermore, the exhaust gases
may turn slightly bluish while the engine is
heating. The quantity of exhaust gases will
depend on the outside temperature.
Filter pre-heater
Vehicles with a diesel engine are fitted with a
fuel filter pre-heating system. This ensures
that the fuel system remains operational to
approx. -24 °C (-11.2 °F), provided you use
winter-grade diesel which is safe to -15 °C
(+5.0 °F).
However, if the fuel has waxed to such an ex-
tent that the engine will not start at tempera-
tures of under -24 °C (-11.2 °F), simply place
the vehicle in a warm garage or workshop for
a while to heat up.
Auxiliary heater
Vehicles with a diesel engine may be fitted
with an auxiliary heater. The heater runs off
the fuel from the fuel tank. On doing so,
smells and steam may be noticed outside the
vehicle for a short period. This is normal and
it is not an indication of a fault in the vehicle.
Whenever there is little fuel in the tank (re-
serve), the auxiliary heater automatically
switches off.
Checking and refilling levels
WARNING
Never use start boosters. An aerosol start
booster could explode or cause a sudden rise
in engine speed leading to engine damage
and serious injury.
CAUTION
● The vehicle is not prepared for the use of
biodiesel. Never, under any circumstances re-
fuel with biodiesel. It could damage the fuel
system and subsequently lead to engine
faults!
The addition of biodiesel to diesel by the
●
diesel producer according to Standard EN 590
or other equivalent (DIN 51628 in Germany,
for example) is authorised and causes no
type of damage to the engine or the fuel sys-
tem.
● The diesel engine has been designed for to
use diesel fuel exclusively. Therefore, never
use petrol, fuel oil or other unsuitable fuels.
The composition of these fuels may signifi-
cantly damage the fuel system and the en-
gine.
● The use of diesel fuels with a high sulphur
percentage could considerably reduce the
service life of the diesel particulate filter.
Your technical service centre will be able to
tell you which countries have diesel with a
high sulphur content.
Information on fuel consumption
The consumption and emission values indi-
cated do not refer to one specific vehicle.
They are only to be used to compare the val-
ues of the different vehicle versions. The fuel
consumption and CO emissions of a vehicle
2
not only depend on the effective use of fuel.
They also depend on your driving style and
other non-technical factors.
Calculation of fuel consumption
Fuel consumption and emission values are
determined according to the current version
of the 715/2007/EC or 80/1268/EEC regula-
tion and are valid for the vehicle kerb weight.
The specifications do not refer to an individu-
al vehicle. Two measuring cycles are carried
out on a rolling road test bed to calculate fuel
consumption. The test criteria are as follows:
Measurement of the urban cycle starts
Urban cy-
with an engine cold start. City driving is si-
cle mulated below at between 0 and 50 km/h
(31 mph).
In the road cycle simulation, the car under-
goes frequent acceleration and braking in
Road cycle all gears, as in normal everyday driving.
The road speed ranges from 0 to
120 km/h (0 and 75 mph).
The average combined consumption is cal-
culated with a weighting of around 37 %
Combined
for the urban cycle and 63 % for the road
cycle.
