If you have to use petrol fuel with an insufficient octane number in an emergen-
■
cy, the engine must be driven only at medium speeds and low load. Avoid high
speeds and high engine load. Otherwise, engine damage may occur! Refuel with
fuel of a sufficient octane number as soon as possible.
Fuels which are labelled at the pump as containing metal must not be used. Al-
■
so, LRP (lead replacement petrol) fuels contain metallic additives in high concen-
trations. Risk of engine damage!
Even inadvertently filling the fuel tank only once with leaded petrol can cause a
■
deterioration in the catalytic efficiency and considerable damage to the catalytic
converter.
Diesel fuel
First read and observe the introductory information and safety warn-
ings
on page 94.
Diesel fuel
Diesel fuel must meet the European standard EN 590 (in India IS 1460:2005).
For diesel fuels with higher sulphur content, shorter service intervals ap-

. Information on countries which have an increased
sulphur content in diesel fuel can be obtained from a ŠKODA Partner.
Fuel additives, so-called flow improvers, or similar products may not be added to
the diesel fuel.
Winter-grade diesel
When using "summer-grade diesel" at temperatures below 0 °C (+32 °F), opera-
tional problems may occur because the fuel becomes viscous as a result of paraf-
fin separation. Therefore, there is in Germany for example "winter-grade diesel"
available during the cold season, which is safe to use even below -20 °C (-4 °F).
It is often the case in countries with different climatic conditions that diesel fuels
available have a different temperature characteristic. Your ŠKODA Partner and
petrol stations in the specific country provide information on their common diesel
fuels.
It is normal that a cold diesel engine emits louder noise at cold temperatures than
in warm weather. In addition, the exhaust gases during starting and in the warm-
up phase may be slightly bluish. The amount of exhaust gas depends on the out-
side temperature.

General Maintenance
Filter preheating
Diesel vehicles are equipped with a filter preheating system. This makes the fuel
system – when using winter-grade diesel that is resistant to cold down to -15 °C
(+5 °F) – safe to use down to approx. -24 °C (-11 °F).
However, if – at temperatures below -24 °C (-11 °F) – the fuel has become so vi-
cious that the engine will not start, put the vehicle for some time in a heated ga-
rage or workshop to warm up.
WARNING
Never use a start booster. A start booster may explode or cause a sudden rev-
ving of the engine, causing serious injuries and damage to the engine.
CAUTION
The vehicle is not suitable for use of biodiesel and must never be refuelled and
■
driven with biodiesel. Otherwise, damage can occur to the fuel system and engine
damage may be the result!
Addition of biodiesel as part of EN 590 or an equivalent standard (e.g.,
■
DIN 51628 in Germany) to the diesel fuel by the diesel fuel producer is permitted
and does not damage the engine or the fuel system.
The diesel engine was designed exclusively for the use of diesel fuel. Therefore,
■
do not use petrol, heating oil or other unsuitable fuels. The ingredients of these
fuels can damage the fuel system and engine considerably.
Information on fuel consumption
First read and observe the introductory information and safety warn-
ings
on page 94.
The indicated fuel consumption and emission levels are not related to a specific
vehicle, but are merely for purposes of comparison between different vehicle
types. The fuel consumption and CO
the efficient utilisation of fuel by the vehicle, but are also influenced by the driv-
ing style and other non-technical factors.
Determination of fuel consumption
The fuel consumption and emission levels were determined according to Directive
715/2007/EC or 80/1268/EEC in the version currently in force and apply to the
specified vehicle's unloaded weight. The figures do not refer to a specific vehicle.
