WARNINGInstructions for filling the reserve canister■Never fill the reserve can inside the vehicle.■
Never place the reserve can on the vehicle.
■
Always place the reserve can on the floor.
■
We do not recommend carrying any fuel canisters in your vehicle for safe-
ty reasons. in the event of an accident, these canisters can become dam-
aged and fuel may escape – risk of fire!
CAUTION
■ The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Not continue refuelling.■
Be careful when filling diesel fuel from the spare canister and then do this
slowly and cautiously – danger of contaminating the body.
Note
The fuel tank has a capacity of about 35 litres, including a reserve of approx.
4 litres .
Lead-free petrol
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap.
Read and observe
and on page 102 first.
The vehicle can only be operated with unleaded petrol that meets the EN 2281)
standard.
All petrol engines can be operated using petrol that contains at most 10% bio-
ethanol (E10).
Unleaded petrol min. 95 RON / ROZ
Use unleaded fuel with the octane rating 95 RON or higher.
In an emergency petrol with the octane ratings 91, 92 and/or 93 RON can also
be used, but may result in a slight loss in performance and slightly increased
fuel consumption. Continue driving at medium engine speeds and minimum
engine load »
.
Refuel using petrol of the prescribed octane number as soon as possible. 

103Inspecting and replenishing

Fuel additives
Unleaded petrol in accordance with the EN 228 standard 1)
meets all the condi-
tions for a smooth-running engine. We therefore recommend that no fuel ad-
ditives are used. This can result in considerable damage to parts of the engine
or the exhaust system.
CAUTION
■ Even one filling of the tank with petrol that does not meet the standards can
lead to serious damage to parts of the exhaust system!■
If a fuel other than unleaded fuel which complies to the above mentioned
standards (e.g. leaded petrol) is put in the tank by mistake, do not start the en-
gine or switch on the ignition. Extensive damage to engine parts can occur.
CAUTION
■ If petrol with a lower octane number than the one prescribed is used do not
drive with a high engine speed. A high engine load can severely damage en-
gine components.■
Even in the event of an emergency, petrol of a lower octane number than 91
RON must not be used, otherwise the engine can be severely damaged.
CAUTION
In no case may fuel additives with metal components be used, especially not
with manganese or iron content. There is a risk of causing severe damage to
parts of the engine or exhaust system.
CAUTION
Fuels with metal components, such as LRP (lead replacement petrol) must
not be used. There is a risk of causing severe damage to parts of the engine
or exhaust system.
Note
■ Unleaded petrol that has a higher octane number than that required by the
engine can be used without limitations.■
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of pet-
rol with a higher octane number than 95 RON can increase the power and re-
duce fuel consumption.
Refuelling CNG (compressed natural gas)Fig. 104
Natural gas filler tubes
Read and observe
and on page 102 first.
Natural gas refuelling can be carried out if the following condition is fulfilled. The engine and the ignition are switched off.
The gas filler tube for refuelling with natural gas is located behind the fuel fill-
er flap next to the petrol filler tube.
The filling couplings of the natural gas refuelling systems may differ in han-
dling. When refuelling with natural gas at unfamiliar refuelling systems, you
should seek help from trained fuel station staff. If unsure, have the refuelling
done by trained fuel station staff.

The fuel tank is full when the compressor of the refuelling system automati-
cally switches off. To stop the refuelling operation prematurely, press the
“Stop ” button of the refuelling system.
Closing the filler cap

er tube.
If the sealing ring

has slipped onto the filling coupling, reinsert it into the
gas filler tube. 

104General Maintenance

›Plug the cap A onto the gas filler tube.›Close the bonnet.
The natural gas refuelling systems have an overfill protection relating to the
outdoor temperature. At very high outside temperatures, it may happen that
the gas tank may not be fully refuelled.
The natural gas system of your vehicle is suitable both for “slow fuelling” (fuel-
ling from small compressors) and for “quick fuelling” (fuelling from natural gas
stations with large compressors).
If the vehicle is parked for a longer period of time immediately after refuelling,
the situation may arise in which the pointer of the fuel tank gauge does not
indicate exactly the same level as was the case immediately after refuelling
when the engine is restarted. This is not due to any system leakages but a
drop in pressure in the natural gas fuel tank due to technical reasons after a
cooling phase directly after refuelling.
The maximum lifetime of the gas tank is 20 years.
The capacity of the natural gas fuel tank is about 11 litres, of which about 1.5
litres are in reserve.
The capacity of the gasoline fuel tank is about 10 litres, of which about 5 litres
are in reserve.WARNING■ When refuelling, never get into the vehicle. If you have to get into your
vehicle in exceptional cases, touch a metal surface before you touch the
filling coupling again. This will avoid electrostatic discharges, which may
generate sparks. Sparks can cause a fire during refuelling.■
Natural gas is highly explosive and highly flammable.
Note
During the filling process sounds are heard which are harmless. If you are un-
sure which service station staff to use, ask the petrol station staff.CNGFig. 105
Position of the CNG label(s).
Read and observe
and on page 102 first.
A G-TEC-vehicle may be operated with CNG and petrol.
In some countries, national legislation requires that vehicles with CNG opera- tion be identified by one of the labels » Fig. 105.
Position of the CNG label » Fig. 105.
Natural gas quality and consumption
Depending on the natural gas supplier, the natural gas quality (heating value) may vary. The engine system adjusts automatically to the natural gas quality.
Automatically switching over from natural gas mode to petrol mode
The vehicle automatically switches from natural gas to petrol, for example, if one of the following cases occurs.
▶ With an empty gas tank or not enough pressure in the tank.
▶ After refuelling with natural gas.
▶ At very low surrounding temperatures.
Use up all the petrol in the fuel tank once every six months until the warning
light  illuminates and then refill with petrol. This is to ensure that the fuel
system functions correctly and to preserve the quality of the fuel.
Gas smell
If you smell gas proceed as follows. ▶ Stop the vehicle.
▶ Put out cigarettes.
▶ Switch off the ignition.
▶ Open doors and the boot lid to ventilate the vehicle sufficiently. 
