Checking and refilling levels
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. 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
2 emissions of a vehicle
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:
Urban cy-
cleMeasurement of the urban cycle starts
with an engine cold start. City driving is si-
mulated below at between 0 and 50 km/h
(31 mph).
Road cycle
In the road cycle simulation, the car under-
goes frequent acceleration and braking in
all gears, as in normal everyday driving.
The road speed ranges from 0 to
120 km/h (0 and 75 mph).
Combined
The average combined consumption is cal-
culated with a weighting of around 37 %
for the urban cycle and 63 % for the road
cycle.

Checking and refilling levels
carried out by a specialised workshop if you
are uncertain. Negligent work can cause seri-
ous injury. WARNING
If the vehicle moves unexpectedly, this could
cause serious injury.
● Never work under the vehicle if it has not
been immobilized. If you must work under-
neath the vehicle with the wheels in contact
with the ground then it should be parked on
flat ground, the wheels should be prevented
from moving and the key should be removed
from the ignition.
● If you have to work underneath the vehicle,
you must use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. The jack is not intended for this kind of
work and its failure could lead to severe inju-
ries. WARNING
The engine compartment is a dangerous area
capable of causing serious injury.
● For all type of work, always take the utmost
precautions, work carefully and note the gen-
eral safety standards in force. Never take per-
sonal risks.
● Never work on the engine or in the engine
compartment if you are not familiar with the
necessary operations. If you are not sure
about procedures then visit a specialised
workshop to carry out the necessary work. Working incorrectly can cause serious inju-
ries.
●
Never open the bonnet if you see steam or
coolant escaping from the engine compart-
ment. This may cause serious burns. Always
wait until you cannot see or hear the sound of
steam or coolant coming from the engine
compartment.
● Always allow the engine to cool down be-
fore opening the bonnet.
● Contact with hot elements of the engine
and the exhaust system can cause burns.
● Once the engine has cooled, follow the in-
structions below before opening the bonnet:
– Turn on the electronic parking brake and
place the gear selector lever in P or the
gearbox lever in neutral.
– Remove the key from the ignition.
– Keep children away from the engine com-
partment and never leave them unsuper-
vised.
● When the engine is warm or hot, the cool-
ing system is pressurised. Do not unscrew
the cap on the expansion tank when the en-
gine is hot. Otherwise, coolant may spray out
under pressure causing burns and serious in-
jury.
– Carefully and slowly unscrew the cap an-
ticlockwise, gently pressing down on it.
– Always protect your face, hands and arms
from hot coolant and steam using a large,
thick cloth. ●
When refilling liquids, avoid spilling them
on parts of the engine and the exhaust sys-
tem. Spilled liquids could cause a fire. WARNING
The high voltages of the electrical system can
give electric shocks as well as causing burns
and serious injury and possibly even death!
● Never cause short circuits in the electrical
system. The battery could explode.
● To minimise the risk of electric shock and
serious consequences while the engine is
running or starting the engine, note the fol-
lowing:
– Never touch the electrical wiring of the
ignition system.
– Never touch electric cables or the gas dis-
charge lamps. WARNING
In the engine compartment, there are rotat-
ing parts that could cause serious injury.
● Never place your hands on or near the radi-
ator fan. Touching the rotor blades could seri-
ously harm you. The ventilator works accord-
ing to the engine temperature and could start
suddenly even when the ignition is turned off
and the key is removed.
● If any work has to be performed when the
engine is started or with the engine running,
there is an additional, potentially fatal, safety » 215Technical specifications

tual kerb weight of the vehicle are noted on
the vehicle data sticker.
The fuel consumption and emissions figures
given are based on the vehicle weight cate-
gory, which is determined according to the
engine/gearbox combination and the equip-
ment fitted.
The consumption and emission figures are
calculated in accordance with the EC test re-
quirements 1999/100/EC. These test re-
quirements specify a realistic test method
based on normal everyday driving.
The following test conditions are applied:Urban
cycleThe urban cycle starts with an engine cold
start. City driving is then simulated.
Extra

cycleIn the extra urban cycle simulation the vehi-
cle frequently accelerates and brakes in all
gears, as in normal everyday driving. The
road speed ranges from 0 to 120 km/h (0 to
75 mph).
Total
con-
sump-
tionThe average total consumption is calculated
with a weighting of around 37% for the ur-
ban cycle and 63% for the extra urban cycle.
CO 2
emis-
sionsThe exhaust gases are collected during both
driving cycles to calculate carbon dioxide
emissions. The gas composition is then ana-
lysed to evaluate the CO 2 content and other
emissions. Note
Actual consumption may vary from quoted
test values, depending on personal driving
style, road and traffic conditions, the weather
and the vehicle condition. Weights
Kerb weight refers to the basic model with a
fuel tank filled to 90% capacity and without
optional extras. The figure quoted includes
75 kg to allow for the weight of the driver.
Special versions, optional equipment fittings
or retro-fitting accessories will increase the
weight of the vehicle

WARNING
● Please note that the centre of gravity may
shift when transporting heavy objects; this
may affect vehicle handling and lead to an ac-
cident. Always adjust your speed and driving
style to suit road conditions and require-
ments.
● Never exceed the gross axle weight rating
or the gross vehicle weight rating. If the per-
missible axle load or the permissible total
weight is exceeded, the driving characteris-
tics of the vehicle may change, leading to ac-
cidents, injuries and damage to the vehicle. 275
