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 145, fig. 141 .
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 145.
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.
You can find information on refuelling page 145.

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 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 EN 590 prescribes diesel fuel class for certain periods of the
year which can also be purchased at the co rresponding 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 characteri stic. The specialist garages and the filling
stations in the country co ncerned will be able to pr ovide you with information
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.RefuellingThe filler tube of the fuel reservoir is locate d in the rear right side part of the vehicle.Opening the fuel filler cap– Open the fuel filler flap with the hand.
– On vehicles without remote unlocking of the fuel filler flap from the driver's seat,
unlock the fuel filler cap on the fuel filler tube by turning the vehicle key to the left.

Oil level within range –You may top up the oil. It is possible that the oil level may then be within range
after doing this.Oil level within range –You must top up the oil page 151. It is sufficient, once this 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 during 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 wi ll indicate whether the oil level is too low
 page 29. In this case, check the oil level as soon as possible. Top up with an appro-
priate 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.
Replenishing engine oil– Inspecting the engine oil level page 150.
– Unscrew the cap of the engine oil filler opening page 150, fig. 146 .
– Pour in a suitable grade of oil in portions of 0.5 litres page 149. – Inspect the oil level
page 150.
– 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 148, “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 150. 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 18.
WARNING

Only carry out the engine oil change, if you have the required professional
knowledge!

Read and observe the warning notes page 148, “Working in the engine
compartment” before working in the engine compartment.

Let the engine cool down - risk of burning from hot oil.

Wear an eye protection - risk of caustic burns due to oil splashes.

Oil is toxic! Store old oil in a safe place out of the reach of children and unau-
thorized persons until you dispose of it properly.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.
