WARNING■
The operating instructions of the refuelling system must always be fol-
lowed.■
Do not smoke when refuelling and do not use a mobile phone.
■
The fuel and fuel vapours are explosive - risk to life!
CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of
fuel can cause misfiring, which can result in damage to parts of the engine and
the exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork –
risk of paint damage.
■
If the vehicle was not purchased in the country where it was intended to be
operated, you should check whether the fuel specified by the manufacturer is
offered in the country where the vehicle will be operated. You should also per-
haps check whether the manufacturer has recommended a different fuel for
operation of the vehicle in the corresponding country. If no prescribed fuel is
available, then you must check whether it is permitted by the manufacturer to
operate the vehicle with another fuel type.

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
Do not use fuels with metal components, such as LRP (lead replacement
petrol) . There is a risk of causing severe damage to parts of the engine or ex-
haust system.Note■ Unleaded petrol that has a higher octane number than that required by the
engine can be used without limitations.■
The use of petrol with an octane rating higher than 95 RON in does not re-
sult in either a noticeable increase in power nor lower fuel consumption in ve-
hicles for which unleaded petrol 95/min 92 or 93 RON is specified.
■
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.
Diesel fuel
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap.
Read and observe
and on page 189 first.
The vehicle can only be operated with diesel fuel that meets the EN 5902)
standard.
All diesel engines can be operated using diesel fuel with at most 7% biodiesel
(B7) 3)
.
On the Indian market, your vehicle will only be able to run on diesel fuel com-
pliant with standard IS 1460/Bharat IV. If diesel fuel which complies with this
standard is not available, you can refuel with diesel fuel according to standard
IS 1460/Bharat III in case of emergency.
Operation in winter – Winter-grade diesel fuel
In the cold season, only use “winter-grade diesel fuel” which will still operate
properly even at a temperature of -20 °C.
It is often the case in countries with different climatic conditions that diesel
fuels available have a different temperature characteristic. The ŠKODA Part-
ners and filling stations in the relevant country will be able to provide you with
information regarding the diesel fuels available. 

191Inspecting and replenishing

Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures opera-
tion of a vehicle using diesel fuel down to an environmental temperature of
-24 °C.
Diesel fuel additives
The diesel fuel in accordance with the prescribed standards meets all the con-
ditions for a smooth running engine. We therefore recommend that no diesel
fuel additives are used. This can result in considerable damage to parts of the
engine or the exhaust system.
CAUTION
■ Just filling the tank once with diesel fuel that does not comply with the
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system.■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is used, do not start the engine or switch on the
ignition! Extensive damage to engine parts can occur.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with bio fuel RME, therefore this fuel must
not be filled in the tank and used for driving the vehicle. The use of biofuel
RME can cause considerable damage to parts of the engine or fuel system.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents) into the diesel. This can result in considerable damage to parts of the
engine or the exhaust system.
Refuelling with CNG (compressed natural gas)
Fig. 201
Natural gas filler tubes
Read and observe and on page 189 first.
Natural gas refuelling can be carried out if the following conditions are met.
The vehicle is unlocked.
The engine and the ignition are switched off.
The auxiliary heating and ventilation is switched off » page 118.
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 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 

192General Maintenance

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 approximately 15 kg.
The capacity of the gasoline fuel tank is about 50 litres, of which about 6
lighters 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.
CNG

and on page 189 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. 202.
Position of the CNG label » Fig. 202.
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 all the petrol in the fuel tank at lease 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 leak
If a gas leak is suspected (noticeable odour), proceed as follows. ▶ Stop the vehicle.
▶ Switch off the ignition.
▶ Put out any cigarettes, remove any spark-producing or incendiary items from
the vehicle and immediately switch the engine off.
▶ Open the doors and the boot lid to ventilate the vehicle sufficiently.
▶ Do not continue to drive if the odour persists.
▶ If it is not possible to leave an enclosed area with a vehicle with a gas leak
(e.g. in a tunnel, underpass, garage, ferry, etc.), call the emergency services
immediately.
Seek help from a specialist garage to correct the gas system fault.
In a traffic accident
If a gas leak is suspected in a traffic accident, proceed as follows.
▶ Switch off the ignition.
▶ Put out any cigarettes, remove any spark-producing or incendiary items from
the vehicle and immediately switch the engine off.
▶ Have all the occupants get out.
▶ Prevent people walking past/standing in the immediate vicinity of the acci-
dent vehicle. We recommend standing at least 10 metres from the vehicle.
▶ Inform the emergency services that it is a natural gas vehicle.
Regular gas system checks
Regular gas system checks must be carried out in a specialist workshop on
natural gas-powered vehicles. The vehicle owner is responsible for ensuring
tests are conducted properly. 193Inspecting and replenishing

Every 2 years
▶ Check the filler cap.
▶ Check the condition of fuel filler tubes and the sealing ring in the fuel filler
tubes, and clean the sealing ring if necessary.
▶ Check the gas system for leaks.
Every 4 years
▶ Inspect the gas tank.
Every 20 years ▶ Replace the gas tank.WARNING■ Do not underestimate the smell of gas in the car or when refuelling - risk
of fire, explosion and injury.■
The natural gas tanks in the vehicle must not be exposed to unwanted
heat sources.
