Fuel
Fuel for petrol engines
Only
use unleaded fuel that complies
with DIN EN 228.
Fuels with ethanol content greater
than 5% may only be used if the
vehicle has been specifically
developed and approved for these
fuels.
Use fuel with the recommended
octane rating 3 209. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly
increases fuel consumption. Caution
Use of fuel with too low an octane
rating could lead to uncontrolled
combustion and engine damage.
Fuel for diesel engines
Only use diesel fuel that complies
with
DIN EN 590. The fuel must have
low sulphur content (max. 50 ppm).

Driving and operating
147
Do not use marine diesel oils, heating
oils or entirely or partially plant-based
diesel fuels, such as rape seed oil or
bio diesel, Aquazole and similar
diesel-water emulsions. Diesel fuels
must not be diluted with fuels for
petrol engines.
The flow and filterability of diesel fuel
are temperature-dependent. When
temperatures are low, refuel with
diesel fuel with guaranteed winter
properties.
Fuel for natural gas
operation
Use natural gas with a methane
content of approx. 78 - 99 %. L-gas
(low) has approx. 78 - 87 % and H-gas
(high) has approx. 87 - 99 %. Biogas
with the same methane content can
also be used if it has been chemically
prepared and desulphurised.
Liquid gas or LPG must not be used. Refuelling
9
Danger Before refuelling, switch off engine
and any external heaters with
combustion chambers (identified
by
sticker on fuel filler flap). Switch
off any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling. 9
Danger Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by
a workshop.
Fuel filler flap is located at right rear
side of vehicle.
The
fuel filler flap can only be opened
if the vehicle is unlocked.
Page 148 of 228

148
Driving and operating
The fuel filler cap can be retained in
the bracket on the fuel filler flap. Caution
Wipe off any overflowing fuel
immediately.
Natural gas refuelling
When filling with natural gas, remove
the
protective cap from the filler neck. 9
Warning Refuel only with a maximum
output pressure of 250 bar. Use
only temperature compensated
filling stations.
The refuelling procedure must be
completed,
i.e. the filler neck must be
vented. Refit the protective cap.
The capacity of the natural gas tank
depends on outside temperature,
filling pressure and type of refuelling
system.

Fuel consumption - CO 2-
Emissions
The determination of fuel
consumption is regulated by
European directive 80/1268/EEC
(latest edition 2004/3/EC).
The directive is oriented to actual
driving practices: Urban driving is
rated at approx. 1
/3 and extra urban
Page 149 of 228

Driving and operating
149
driving with approx. 2
/3 . Cold starts
and acceleration phases are also
taken into consideration.
The specification of CO 2 emission is
also a constituent of the directive.
The figures given must not be taken
as a guarantee for the actual fuel
consumption of a particular vehicle.
Furthermore, fuel consumption is
dependent on personal driving style
as
well as road and traffic conditions.
All values are based on the EU base
model with standard equipment.
The calculation of fuel consumption
takes account of the vehicle’s kerb
weight, ascertained in accordance
with the regulations. Options may
result in slightly higher fuel
consumption and CO 2 emission
levels and a lower top speed.
Fuel consumption, CO 2 emissions
3 213. Natural gas
The fuel consumption information
was obtained using reference fuel
G20 (methane proportion 99 - 100
mol%) under prescribed driving
conditions. When using natural gas
with a lower proportion of methane,
the fuel consumption can differ from
the specified values.
Towing
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.
Installation dimensions of factory-
fitted towing equipment

Driving characteristics and
towing tips
Before attaching a trailer, lubricate
the
coupling ball. However, do not do
so if a stabiliser, which acts on the
coupling ball, is being used to reduce
snaking movements.
For trailers with low driving stability
and trailers with a permitted gross
vehicle weight of more than 1300 kg
a speed of 80 km/h must not be
exceeded; the use of a stabiliser is
recommended.
Page 150 of 228

150
Driving and operating
If the trailer starts snaking, drive more
slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 220.
Trailer towing
Trailer loads
The permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is
the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified
in the vehicle documents. In
general, they are valid for gradients
up to max. 12 % The permitted trailer load applies up
to the specified incline and up to an
altitude of 1000 metres above sea
level. Since engine power decreases
as altitude increases because of the
air becoming thinner, therefore
reducing climbing ability, the
permissible gross train weight also
decreases by 10 % for every 1000
metres of additional altitude. The
gross
train weight does not have to be
reduced when driving on roads with
slight inclines (less than 8 %, e. g.
motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 208.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (75 kg) is specified on
the towing equipment identification
plate and in the vehicle documents. Always aim for the maximum load,
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.
Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by 90
kg
and the gross vehicle weight rating
by 75 kg. If the permissible rear axle
load is exceeded, a maximum speed
of 100 km/h applies.
Towing equipment Caution
When operating without a trailer,
remove the coupling ball bar.
