Grades of petrol
There are various grades of petrol. Please read ⇒page 255, “Technical Data” in
order to know which grade of petrol your vehicle requires. You will also find the
same information affixed to the inside of the fuel filler flap of your vehicle
⇒ page 207, fig. 193 .
A distinction is made betwee n unleaded and leaded petrol . All Škoda vehicles with
petrol engines are equipped with a cataly tic converter and must therefore be only
driven with unleaded petrol . Unleaded petrol complies with the standard
DINEN228 .
The individual grades of petr ol are distinguished by their octane number (RON).
Please adopt the following procedure if th e grade of petrol which you normally use
is not be available in exceptional circumstances:
•Engines which need unleaded premium petrol 95 RON can also be run on
unleaded regular petrol 91 RON. This does, however, result in a slight loss in
performance.
•Engines which need unleaded premium plus petrol 98 RON can also be run
on unleaded regular petrol 95 RON. This do es, however, result in a slight loss in
performance. You can in exceptional circumstances also use unleaded regular
petrol of 91 RON in the event that neither unleaded premium petrol of 98 RON nor
95 RON is available. Refuel as soon as possible with unleaded premium plus of 98
RON or unleaded premium petrol of 95 RON.
If, in an emergency, the only fuel availa ble is one which has a lower octane number
than that required by the engine then only drive at medium engine speeds and
lower engine loadings.
You can make unlimited use of fuel which has a higher octane number than that
required by the engine. There will, however, be no advantages gained by this in
terms of engine performa nce and fuel consumption! 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. Use a fuel
complying with the standard.
You can find further information on refuelling ⇒page 207, “Refuelling”.
Caution
•Filling the tank even only once with le aded petrol will result in the catalytic
converter being destroyed.
•Operating the engine with petrol of a low octane number can result in engine
damage at high revolutions or severe engine loading.
Diesel
Diesel fuel
Your vehicle can be operated with diesel fuel, which complies with the standard
DIN EN 590.
Fuel additives
You must not use fuel additives, so-ca lled “flow improvers” (petrol and similar
products) in diesel fuel.
If the quality of the diesel fuel is p oor, it is then necessary to drain the fuel filter
more often than stated in the Service schedule.
You can find information on refuelling ⇒page 207, “Refuelling”.
Caution
•Use a fuel which complies with the standard DINEN590. Filling the tank even
only once, which does not comply with th e standard, can result in damage to the
fuel system.
•Water which has collected in the fuel filter can result in engine problems.

•Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must not
be refuelled and driven. Using this fuel (RME) can lead to damage to the engine or
the fuel system.
Operation in winter
Winter-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 be comes viscous as a result of paraffin
separation.
It is therefore the case that DIN EN 590 prescribes diesel fuel class for certain
periods of the year which can also be pu rchased 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 diff erent climatic conditions that diesel fuels
available have a different temperature characteristic. Škoda Service Partners and
filling stations in the count ry concerned will be able to provide you with informa-
tion 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.
Refuelling
The filler flap is automatically unl ocked or locked* with the central
locking.
Opening the fuel filler cap
– Press onto the left side of the fuel filler flap ⇒fig. 192 .
– The fuel filler cap on the fuel filler tube must be unlocked to the left using the vehicle key (only valid for vehicles which do not have auto-
matic unlocking of the fuel filler flap).

from above on the fuel filler flap ⇒page 207, fig. 193 .
Closing fuel filler cap
– Screw on the cap by turning it to the right until it is heard to lock.
– The fuel filler cap on the fuel filler tube must be locked to the right using the vehicle key (only valid for vehicles which do not have auto-
matic locking of the fuel filler flap).
– Press the fuel tank flap closed.
The correct grade of fuel for your vehicle as well as the tyre size and inflation pres-
sures are stated on a sticker affixed to the inside of the fuel filler flap. Further infor-
mation on fuel ⇒page 206, “Fuel”.
The fuel tank has a capacity of about 55 litres.
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 da maged in the event of an accident and
fuel may leak out.
Caution
•Before refuelling it is necessary to switch off the auxiliary heating system (auxil-
iary heating and ventilation) *.
•Remove any fuel which has spilled onto the paintwork of your vehicle immedi-
ately - risk of paint damage!
•Vehicles fitted with catalytic converter should neve r be allowed to let the fuel
tank to 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. Otherwis e you are unintentionally 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.
•T h e f u e l t a n k i s f u l l j u s t a s s o o n a s t h e pump nozzle switches off for the first time,
provided the nozzle has been operated pr operly. Do not continue refuelling -
otherwise the expansion volume is filled up.

Working in the engine compartment
Particular care is required when carrying out any work in the engine
compartment!
There is a risk of injuries, scalding, accidents and fire when working in the
engine compartment, e.g. inspecting an d replenishing oil and other fluids. For
this reason, it is essential to comply with the warning instructions stated below and with the general applicable rules of safety. The engine compart-
ment of your car is a hazardous area
⇒ .
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi ng! Wait long enough until the steam
or coolant has stopped escaping.
•Switch off the engine and pull out the ignition key.
•Apply the handbrake firmly.
•If your vehicle is fitted with a manual gearbox, move the gearshift lever
into Neutral, or if it is fitted with automatic gearbox, move the selector lever
into position P.
•Allow the engine to cool down.
•Keep children clear of the engine compartment.
•Never spill oil and other fluids over the hot engine. Such fluids (e.g. the
antifreeze contained in the coolant) may ignite!
•Avoid short circuits in the electrical system - particularly on the battery.
•Never place your hand into the radiator fan as long as the engine is still
warm. The fan might suddenly start running!
•Never open the cap of the coolant expa nsion bottle as long as the engine
is still warm. The cooling system is pressurized!

Engine oil
Engine oil specifications
The grade of engine oil should be selected in accordance with
precise specifications.
The engine of your vehicle has been fact ory-filled with a high-grade oil which you
can use throughout the year - exce pt in extreme climatic regions.
You can mix various oils together with each other when refilling with oil. This does
not, however, apply for models with flexible service intervals (QG1).
Engine oils are, of course, undergoing co ntinuous further development. Thus the
information stated in this Owner's Manual is only correct at the time of publication.
Škoda Service Partners are informed by Škoda Auto a.s. about current changes. This
why you should always have engine oil changed by your Škoda Service Partner.
The specifications (VW standards) stated in the following must be indicated sepa-
rately or together with other specifications on the bottle.
Engine oil specifications for vehicles with fixed service intervals (QG0, QG2) Engine oil specifications for models with flexible service intervals (QG1)
Caution
Only the above-mentioned oils may be used on vehicles with flexible service inter-
vals (QG1). We recommend always refilling with oil of the same specification since
this will maintain the properties of the oi
l. In exceptional cases, you must top up
only once engine oil complying with Specification VW 502 00 (only for petrol
engines) or Specification VW 505 01 (only for diesel engines) to maximum 0.5 litres.
You must not use other engine oi ls - risk of engine damage!
Note
•Before a long drive we recommend th at you purchase and carry with you
engine oil which complies with the specif ication for your vehicle. Consequently,
you will always have the correct engine oil for refilling.
•We recommend using a preservative fr om the Škoda original accessories
offered by your Škoda dealer.
•For further information - see Service shedule.

Check engine oil level
The dipstick indicates the level of oil in the engine.
Checking the oil level
– Park the vehicle on a horizontal surface.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 210.
– Wait a few minutes and pull out the oil dipstick.
– Wipe off the dipstick with a clea n cloth and insert it again fully.
– Then withdraw the dipstick ag ain and read off the oil level.
Oil level within range
– You must not top up the oil.
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 213. It is sufficient, once this is done,
to keep the oil level is 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 consumpt ion may be slightly higher 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* will indicate ⇒page 30, “Engine oil
level* ” whether the oil level is too low. In this case, check the oil level as soon as
possible. Top up with an a ppropriate quantity of oil.
Caution
•The oil level must on no account ex tend 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 prev ailing to top up with oil. Switch of the engine and contact and
obtain professional assistance from a specialist garage.
Replenishing engine oil
– Inspecting the engine oil level ⇒page 213.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 212,
“Engine oil specifications”.
