FuelPetrolGrades of petrolYour vehicle can only be operated with unleaded petrol, which complies with the
standard EN 228. The individual grades of petrol are distinguished by their octane
number (RON). On the inside of the fuel filler flap, you will find the information
regarding the RON required by your engine  page 159.
Prescribed fuel - unleaded petrol 95/91 RON
Use unleaded petrol 95 RON. You can also use unleaded petrol 91 RON, but this leads
to a slight loss in performance.
If, in case of necessity, the vehicle must be refuelled with petrol of a lower octane
number than the one prescribed, you must co ntinue driving at medium engine speeds
and low engine load. Driving at high engine speeds or a high engine load can severely
damage the engine! Refuel as soon as possib le with petrol of the prescribed octane
number.
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded petrol 95 RON.
In case of necessity, you can refuel with petrol 91 RON if petrol 95 RON is not avail-
able. You must continue driving at medium engine speeds and minimum engine load.
Driving at high engine speeds or a high engine load can severely damage the engine!
Refuel as soon as possib le with petrol of the prescribed octane number.
Even in case of necessity, you must not use petrol of a lower octane number than 91,
otherwise the engine can be severely damaged!
You can find further information on refuelling page 159, “Refuelling”.
Unleaded petrol with higher octane number
You can make unlimited use of unleaded pe trol which has a higher octane number
than the one prescribed. On vehicles with prescribed unleaded petrol
95/91 RON, the use of petrol with a
higher octane number than 95 does not result in a noticeable power increase or a
lower fuel consumption.
On vehicles with prescribed unleaded petrol min. 95 RON, the use of petrol with a
higher octane number than 95 does not result in a power increase or a lower fuel
consumption.
Caution

All Škoda vehicles with petrol engines are equipped with a catalytic converter and
must be only driven with unleaded petrol. Fi lling the tank even only once with leaded
petrol will result in the cata lytic converter being destroyed!

Only use unleaded petrol which complies with the standard EN 228.

If you use petrol with a lower octane num ber than the one prescribed, the engine
can be severely damaged!Note
The handling, performance and life of your engine are determined to a significant
extent by the quality of the fuel. Do not use any petrol additives.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.
If the quality of the diesel fuel is poor, it is then necessary to drain the fuel filter more
often than stated in the Service schedule.

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 stan dards (e.g. petrol), on no account start
the engine! This can result in severe engine damage! Contact a specialist garage.

Water which has collected in the fuel fi lter can result in engine problems.

Your vehicle is not adapted for use of biofue l (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 th e diesel becomes 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 fuel 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 countries 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 concer ned will be able to provide you with infor-
mation regarding the diesel fuels available. Prewarming fuel
The vehicle is fitted with a fu
el 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.RefuellingFig. 133 Right rear side of the vehicle: Fuel filler flap / fuel filler flap with cap unscrewedOpening the fuel filler cap– Open the fuel filler flap with the hand.

The correct grades of fuel for your vehicle are stated on a sticker affixed to the inside of
the fuel filler flap. Further information on fuel  page 158.
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

Remove any fuel which has spilled onto th e paintwork of your vehicle immediately
- risk of paint damage!

On vehicles fitted with a catalytic converte r, never let the fuel tank run completely
empty. An irregular supply of fuel to the engine can result in misfiring and unburnt fuel
may get into the exhaust system, which may result in overheating and damage to the
catalytic converter.

Make sure that the valve is not pressed into the filler tube when inserting the pump
nozzle into the filler tube. Otherwise you are unintentiona lly filling up the volume,
which in case of heat can cause an expansion of the fuel. This can lead to an overflow
of fuel or damage to parts of the fuel reservoir.

The fuel tank is full just as soon as th e pump nozzle switches off for the first time,
provided the nozzle has been operated prop erly. Do not continue refuelling - other-
wise the expansion volume is filled up.Note
The fuel tank has a capacity of about 55 litres, containing a reserve of 7litres.s16g.4.book Page 160 Wednesda y, February 10, 2010 3:53 PM

Oil level within range
–You must top up the oil. It is sufficient, once th is is done, to keep the oil level within
range .
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 if the engine has been
operating at high loads, for example duri ng a lengthy motorway trip during the
summer months, towing a trailer or negotiating a high mountain pass, but not above
this .
The warning light in the instrument cluster* will indicate page 28 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.
WARNING
Read and observe the warning notes page 162, “Working in the engine
compartment” before working in the engine compartment.
Caution

The oil level must on no account 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.
Replenishing engine oil– Inspect the oil level page 163.
– Unscrew the cap of the engine oil filler opening. – Wipe off the oil from the sealing surface of the cover and on the counterpart using
a clean cloth.
– Pour in a suitable grade of oi l in portions of 0.5 litres page 208.
– Inspect the oil level page 163.
– 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 162, “Working in the engine
compartment” before working in the engine compartment.For the sake of the environment
The oil level must on no account be above the range page 163. Oil will otherwise
be drawn in through the cr ankcase ventilation and may pass through the exhaust
system to atmosphere. The oil may 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.
WARNING

Only carry out the engine oil change, if you have the required professional
knowledge!

Read and observe the warning notes page 162, “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 en gine 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.

In view of the problems involved in prop erly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you have
the oil and oil filter change carried out by an authorised Škoda Service Partner.Note
After your skin has come in contact with th e oil, you must thoroughly wash your skin.Cooling systemCoolant
The job of the coolant is to cool the engine.The cooling system does not require any maintenance under normal operating condi-
tions. The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture not only provides antifreeze protection down to -25°C but also protects
the cooling and heating system from corrosion. It also prevents the formation of scale
and significantly increases the boiling point of the coolant.
You must therefore not reduce the concentration of antifreeze agent in the coolant by
adding water, also not during the summer mo nths or in countries with a warm climate.
The concentration of coolant additive in the coolant must be at least 40%.
You can increase the amount of antifreeze in the coolant if a higher concentration of
antifreeze is necessary for climatic reasons but only up to 60% (antifreeze protection
down to approx. -40°C). The antifreeze prot ection tails off above that concentration.
Vehicles exported to countries with a cold climate (e.g. Sweden, Norway, Finland) are
already factory-filled with a coolant which offers antifreeze protection down to about
-35°C. In these countries the concentration of coolant additive should be at least 50%. Coolant
The cooling system is factory-
filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the antifr eeze agent G13 (purple in colour).
We recommend that you contact a specialist garage if you have any questions
regarding the coolant or if you wish to fill up with a different coolant.
A specialist garage can also supply you with the correct coolant additives.
Coolant capacity
Caution

Other coolant additives may cause operational problems which, in particular,
involves significantly reduci ng the anticorrosion effect.

Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequenc e of this, result in major engine damage.Petrol engines
