CAUTION

Inspecting and replenishing

Fuel

■

Never drive until the fuel tank is completely empty! 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.

■

 Introduction

■

If you would like to operate your vehicle in countries other than those with

the intended weather conditions, please contact a ŠKODA partner. They will

tell you whether the fuel specified by the manufacturer is offered in that coun-

try and/or whether the manufacturer will sanction operating the vehicle with

another fuel.

CAUTION

Petrol additives (additives)

Unleaded petrol in accordance with the prescribed standards meets all the

conditions for a smooth running engine. We therefore do not recommend mix-

ing fuel additives into the petrol - risk of engine damage or damage to the ex-

haust system.

Hold the fuel cap hold firmly, lock with the key clockwise and remove the

■

key.

Close the fuel filler flap until it clicks into place.

Unleaded petrol

■

The following additives may not be used - risk of engine damage or dam-

age to the exhaust system!

 Read and observe and on page 109 first.

■

Additives with metal components (metallic additives), in particular with

manganese and iron content.

Fuels with metallic content (e.g. LRP - lead replacement petrol).

The correct fuel for the vehicle is specified on the inside of the fuel filler flap

» Fig. 134 on page 109.

■

The vehicle can only be operated with unleaded petrol containing a maximum

of 10% bioethanol (E10).

Note

■

Unleaded petrol that has a higher octane number than that required by the

engine can be used without limitations.

On vehicles using the prescribed unleaded petrol of min. 95 RON, the use of

petrol with a higher octane number than 95 RON can lead to an increase in

power and reduction in fuel consumption.

Unleaded petrol must meet European standard EN 228 (in Germany DIN

51626-1 or E10 for unleaded petrol with octane numbers 95 and 91).

■

Specified petrol is 95 RON / ROZ

Use min. 95 ROZ petrol.

Refuelling with CNG (compressed natural gas)

In an emergency, 91. 92 or93 ROZ petrol can be used (slight loss of power,

slightly increased fuel consumption) »

.

CAUTION

The following instructions must be observed, otherwise there is a risk of dam-

age to the engine and to the exhaust system.

■

When petrol with a lower than the prescribed octane is used, only continue

driving at mid-range engine speeds and with minimal strain on the engine. Re-

fuel using petrol of the prescribed octane number as soon as possible.

■

Lower than 91 octane petrol should not be used, even in an emergency!

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.

Fig. 136 Natural gas filler tubes

 Read and observe and on page 109 first.

Natural gas refuelling may vary from station to station. When refuelling with

natural gas at a station unfamiliar to you, you should get someone to instruct

you or allow the fuelling operation carried out by the 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.

Fig. 137 Position of the CNG label(s).

 Read and observe and on page 109 first.

If the car is parked directly after a refuelling operation, on restart the pointer

of the gas gauge may not show exactly the same level as immediately after the

filling process. This is not a leak in the system, but a reduction in pressure due

to the cooling of the gas in the gas tank after refuelling.

A G-TEC-vehicle may be operated with CNG and unleaded petrol.

Positioning of the CNG sticker in natural gas vehicles » Fig. 137.

The maximum lifetime of the gas tank is 20 years.

Automatically switching over from natural gas mode to petrol mode

The vehicle automatically switches from natural gas to petrol, for example, if

the following situations occur.

The capacity of the natural gas fuel tank is about 11 kg, of which about 1.5 kg

are in the reserve tank.

CAUTION

If it is not possible to drive a vehicle with a gas leak out of an enclosed area

(e.g. tunnel, underpass, garage, ferry etc.), call the emergency services imme-

diately.

In the event of contact between the vehicle underbody and an obstacle or in

the event of an accident, the gas container may become damaged. If this is the

case, have the vehicle checked by a specialist garage immediately. If you smell

gas,  stop driving! Switch off the engine and seek assistance from a special-

Specification

To find out which type of engine oil you can use for your vehicle, contact a

specialist garage.

If this oil is not available, other oils can also be refilled. To prevent engine dam-

age, a maximum of 0.5 l of engine oil with the following specifications may be

used until the next oil change: VW 502 00, ACEA A3/ACEA B4 or API SN, (API

If a top up with oil is not possible or the oil level is above range ,  do not

continue driving! Switch off the engine and seek assistance from a specialist

garage.

■

Do not add any additives to the engine oil - risk of engine damage.

Note

■

If the engine oil level is too low, a warning light lights up in the instrument

cluster  » page 27. Nevertheless, we recommend checking the oil level on a

regular basis using the dipstick.

We recommend that you use oils from ŠKODA Original Accessories.

The engine uses up some oil, depending on driving style and operating condi-

tions (up to 0.5 l / 1 000 km). Consumption may be slightly higher than this

during the first 5 000 km.

■

Coolant

Have the oil change carried out by a specialist garage during the inspection.

 Introduction

Check and refill oil under the following conditions.



The vehicle is standing on a horizontal surface.

The engine operating temperature is reached.

The engine is turned off.

The coolant helps to keep the engine temperature down, and consists of water

and coolant additive (with additives that protect the cooling system against

corrosion and prevent furring).

Checking the level

The proportion of coolant additive in the coolant must be 40 to 60 %.

Wait a few minutes until the engine oil flows back into the oil trough.

Pull the dipstick out and wipe with a clean cloth.

Push the dipstick back to the stop and then pull it out again.

Read the oil level and push the dipstick back in.

The correct mix of water and coolant additive should be checked and if neces-

sary corrected by a specialist garage.

A coolant additive which does not correspond to the correct specification

can reduce the anti-corrosion effect of the cooling system - risk of damage to

the cooling system and the engine.

■

If non-distilled (non-demineralised) water has been used to top up, the cool-

ant should be replaced by a specialist garage - risk of engine damage.

A loss of coolant indicates leaks in the cooling system - risk of engine dam-

age. Top up with coolant and then seek assistance from a specialist garage.
