WARNING
Pay attention to any legal requirements if you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for
safety reasons. The canister can be damaged in the event of an accident and fuel
may leak out.
Caution

Even inadvertently filling the fuel tank with another biofuel such as Ethanol°E85
can result in damage to the fuel system.

If you park the car for a lengthy period, fill with petrol complying with (DIN) EN°228,
because Ethanol E85 can contai n low quantities of impurities, which can lead to corro-
sion.For the sake of the environment
If you use Ethanol E85, the CO
2 emission of your vehicl e is lowered up to 5%.
Note

When operating with Ethanol E85, the fuel consumption increases by approx 33%,
as a lower quantity of energy is contained in the bioethanol than in unleaded petrol.

Biofuel Ethanol E85 contains only a low quantity of additives in contrast to
unleaded petrol. Therefore we recommend to fill up the tank with unleaded petrol
complying with EN 228 every 15 000 km (e.g . before the oil change) and run it empty,
so that the engine remains clean. Make sure not to use the whole content of the tank
 page 195, “Refuelling”.

The interval of 15 000 km applies for the oil change.
Operation in winterIf you use biofuel Ethanol E85 at very low temperatures, it is necessary to preheat the
engine before an engine start.
The power socket for the engine preheating is located in the front bumper next to the
fog light  fig. 158.
If an engine preheating is not possible at outside temperatures lower than -10 °C, the
share of unleaded petrol complying with EN 228 must be as high as possible. Thus the
cold start property of the engine is clearly improved.
If there is biofuel Ethanol E85 in the tank and the engine is not preheated, it can lead at
temperatures below -15°C to very p oor or no starting of the engine.
For the sake of the environment
The use of engine preheating at temperatures below -10°C has a positive effect on the
fuel consumption and thus on the environment.The outside temperature

Fuel
194Note
An extension cable used for connecting to the electrical network is located in the
luggage compartment.DieselDiesel fuelYour vehicle can only be operated with diesel fuel, which complies with the standard
EN 590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in Austria).
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and similar prod-
ucts) in diesel fuel.
You can find information on refuelling page 195, “Refuelling”.
Caution

Therefore, your vehicle can only be operated with diesel fuel which complies with
the standard EN 590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in
Austria). Filling the tank even only once wi th diesel fuel which does not comply with
the standard, can result in damage to the engine parts, the lubrication system, the fuel
and exhaust system.

If by mistake you have refuelled with a different fuel other than the diesel fuel
which complies to the above mentioned standards (e.g. petrol), do not start the engine
or switch on the ignition! This can result in severe engine damage! Contact a specialist
garage and have the fuel sy stem of the engine cleaned.

Water which has collected in the fuel fi lter can result in engine problems.

Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must not be
refuelled and driven. The use of biofuel (RME) can lead to damage to the engine or the
fuel system.
Operation in winterWinter-grade diesel fuel
A different grade of diesel fuel is available at filling stations in winter than during the
summer. Using “summer-grade diesel fuel” at temperatures below 0°C can result in
operational problems because the diesel beco mes viscous as a result of paraffin sepa-
ration.
It is therefore the case that the standard EN 590 (standard DIN 51628 in Germany,
standard ÖNORM C 1590 in Austria) is the diesel fu el class prescribed for certain
periods of the year which can also be purc hased at the corresponding time during the
year. “Winter-grade diesel fuel” will still operate properly even at a temperature of -
20°C.
It is often the case in countri es with different climatic conditions that diesel fuels avail-
able have a different temperature characteristic. The authorised Škoda Service Part-
ners and filling stations in the country conc erned will be able to provide you with infor-
mation regarding the diesel fuels available.
Prewarming fuel
The vehicle is fitted with a fuel filter prewarming system. This secures operation of a
vehicle using diesel fuel down to an environmental temperature of -25°C.
Caution
It is not permitted to add the various fuel additives on the market, including petrol, to
diesel fuel in order to improve its flow properties.

Technical Data
It is normal for the engine to consume oil.
The oil consumption may be as much as 0.5
l/1 000 km depending on your style of driving and the conditions under which you
operate your vehicle. The oil consumption may be slightly hi gher than this during the
first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time after
the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range - but not above this, if
the engine has been operating at high load s, for example during a lengthy motorway
trip during the summer months, towing a tr ailer or negotiating a high mountain pass.
The warning light in the instrument cluster* will indicate page 30, “Engine oil pres-
sure ” whether the oil level is too low. In this case, check the oil level as soon as
possible. Top up with an appropriate quantity of oil.
Caution

The oil level must on no ac count extend beyond the range . Danger of damaging
the catalytic converter.

Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Switch the engine off and obtain professional
assistance from a specialist garage, otherwise it could lead to severe engine damage.Note
Engine oil specifications page 237, “Technical Data”.Replenishing engine oil– Inspecting the engine oil level page 198.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres page 240, “Engine oil spec-
ifications”.
– Inspect the oil level page 198.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING

Avoid dripping oil onto hot parts of the engine when topping up will oil - a
risk of fire!

Read and observe the warning notes page 197, “Working in the engine
compartment” before working in the engine compartment.For the sake of the environment
The oil level must on no account extend beyond the range page 198. Oil will
otherwise be drawn in through the crankc ase ventilation and may pass through the
exhaust system to atmosphere. The oil ma y combust in the catalytic converter and
damage it.Changing engine oilThe engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator page 17, “Service Interval Display”.
WARNING

Only carry out the engine oil change, if you have the required professional
knowledge!

Read and observe the warning notes page 197, “Working in the engine
compartment” before working in the engine compartment.

First of all, let the engine cool down, we ar an eye protection and gloves - risk
of caustic burns due to hot oil.Caution
You must not pour any additives into the engine oil - risk of engine damage! Damage,
which results from such product, are excluded from the warranty.
For the sake of the environment

You must on no account pour oil into the ground or into the sewage system.
