Petrol
Grades of petrol
There are various grades of petrol. Please read ⇒ page 269, “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 222, fig. 207 .
A distinction is made between unleaded an d leaded petrol. All Škoda vehicles with
petrol engines are equipped with a catalyti c 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 the 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.
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, howeve r, 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 222, “Refuelling”.
Caution
•Filling the tank even only once with leaded 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.
Biofuel Ethanol E85*
Ethanol E85*
Only valid for vehicles with 1.6/75 kW MultiFuel engine.
Biofuel Ethanol E85 consists of 85% bi oethanol and 15% unleaded petrol
complying with the standard (DIN) EN 228.
Biofuel Ethanol E85 in accordance with th e standard (DIN) EN 228 can be mixed in
any desired ratio with unleaded petrol, see Owner's Manual.
Drive the vehicle for at least 5 minutes without interruption, if biofuel Ethanol E85
has been refuelled, so that the engine co ntrol unit can determine the share of the
biofuel in the fuel. During this period do not drive at top speed of your vehicle or
high engine speeds and not at full throttle . During this process decrease the idling
speed.
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.

Note
An extension cable used for connecting to the electrical network is located in the
luggage compartment.
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-called “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 222, “Refuelling”.
Caution
•Only use fuel which complies with the standard DINEN590. Filling the tank
even only once, which does not comply with the standard, can result in damage to
the fuel system.
•Water which has collected in the fuel fi lter can result in engine problems.
•Your vehicle is not adapted for use of biodiesel, therefore this fuel must not be
refuelled and driven. Using this biodiesel ca n 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 country concerned wi ll 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.

•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 properly. Do not continue refuelling -
otherwise the expansion volume is filled up.

– Grip with the hand under the radiator grille and lift up the bonnet.
– Take the bonnet support out of its holder and set it in the opening designed for it ⇒page 224, fig. 210 .
Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the bonnet support into the hold er designed to hold it.
– Allow the bonnet to drop from a height of about 20 cm into the lock - bonnet do not press down on it !
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.
•For safety reasons, the bonnet must always be properly closed when
driving. One should therefore check that the lock has in fact engaged prop-
erly after closing the bonnet.
•Stop your vehicle immediately while driv ing if you notice that the lock is
not properly engaged and close the bonnet properly - risk of an accident!
Caution
Never open the bonnet using the hand le - danger of causing damage.
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 and 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 ma nual 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!
•Cover over the cap of the coolant expansion reservoir with a large cloth
when opening it as protection for your face, hands and arms from hot steam
or hot coolant.
•Do not let objects, such as e.g cleaning cloth or tools lie in the engine
compartment.
•If you wish to work under the vehicle, you must secure the vehicle from
rolling away and support it with suitable supporting blocks: the car jack is
not sufficient for this - risk of injury!
•In cases where it be necessary to carry out inspection work when the
engine is running there is an additional risk from rotating parts (e.g. the V-
ribbed belt, alternator, radiator fan) and from the high-voltage ignition
system. Please observe in addition the following:

Engine oil
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 225.
– 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 228. It is sufficient, once this is done,
to keep the oil level within range .
It is normal for the engine to consume oi l. The oil consumption may be as much as
0.5 ltr./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 - but not above this,
if the engine has been operating at hi gh loads, for example during a lengthy
motorway trip during the summer months, towing a trailer or negotiating a high
mountain pass.
The warning light in the instrument cluster* will indicate ⇒page 36, “Engine oil
pressure ” 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.
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.

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 concentr
ation of antifreeze agent in the coolant
by adding water, also not during the summ er months 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 an tifreeze protection tails off above that
concentration.
Vehicles exported to countries with a co ld climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant wh ich offers antifreeze protection down to
about -35°C. In these countries the concentr ation of coolant additive should be at
least 50 %.
Coolant
The cooling system is factory-filled with co olant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the same c oolant additive - G12 PLUS-PLUS (purple
in colour) for toppi ng up the system.
Please contact your Škoda Service Partner if you have any questions regarding the
coolant or if you wish to fill up with a different coolant.
Your Škoda Service Partner can also suppl y you with the correct coolant additives.
Caution
•Other coolant additives may cause operational problems which, in partic-
ular, involves significantly redu cing the anticorrosion effect.
•Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th is, result in major engine damage.
Inspecting the coolant level
The coolant expansion bottle is located in the engine compartment on
the right.
– Switch the engine off.
– Open the bonnet ⇒page 224.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 213.
The coolant level when the engine is cold must lie between the
(MIN) and (MAX) markings. The level may also rise slightly above
the (MAX) marking when the engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light
in the instrument cluster ⇒page 37, “Coolant temperature/ Coolant quantity ”.
We nevertheless recommend in specting the coolant level directly at the reservoir
from time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. You
should not merely top up the coolant in the reservoir. It is also important to have
the cooling system inspected without delay by a specialist garage.

Radiator fan
The radiator fan may switch on suddenly.
The radiator fan is driven by an electr ic motor and controlled according to the
coolant temperature.
The radiator fan may continue running fo r up to 10 minutes after the engine has
been switched off - even if the ignition is also off. It may also switch on suddenly
after a certain time, if
•the coolant temperature ha s risen because of an accumulation of heat or
•the warm engine compartment is heated up additionally by strong sunlight.
WARNING
You must therefore be aware when work ing in the engine compartment that
the fan may switch on suddenly - risk of injury!
Brake fluid
Inspecting the brake fluid level
The brake fluid reservoir is located on the left of the engine compartment.
The brake fluid reservoir on right-hand steering models is positioned on
the other side of the engine compartment.
– Switch the engine off.
– Open the bonnet ⇒page 224.
– Inspect the brake fluid level in the reservoir ⇒fig. 214 . The level must
be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear
and automatic adjustment of the br ake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid level
drops significantly within a short time or if it drops below the “MIN” marking. If the
brake fluid level is too low, this is indicated by the warning light ⇒page 40, “Brake
system ” lighting up in the instru ment cluster. In this case stop immediately and
do not drive any further! Obtain professional assistance.
WARNING
•Read and observe the warning notes ⇒page 225, “Working in the engine
compartment” before working in the engine compartment.
•If the fluid level has dropped below the MIN marking, do not drive any
further - risk of accident! Contact a Škoda dealer to obtain professional
assistance.
Replacing brake fluid
Brake fluid absorbs moisture. This causes the fluid to absorb moisture from the
surrounding air over a period of time. Excessive water in the brake fluid may be the
cause of corrosion in the brake system. Th e water content also lowers the boiling
point of the brake fluid. This is why brake fluid must be replaced every two
years.
One may only use new genuine brake fluid from Škoda Auto a.s. The specification
for the brake fluid is “FMVSS 116 DOT 4”.

•Hydrogen is released when you char ge a battery and a highly explosive
gas mixture is produced. An explosion can be caused through sparkling over
during unclamping or loosening of the cable plug while the ignition is on.
•Bridging of the poles will create a short circuit (e.g. through metal
objects, cables). Possible consequences of a short circuit: Melting of lead
struts, explosion and burning of the battery, jets of acid spurting out.
•It is prohibited to work with a naked flame and light, to smoke or to carry
out any activities which produce sparks. Avoid creating sparks when
working with cables and electrical device s. Strong sparking represents a risk
of injury.
•Before carrying out any work on the electrical system, switch off the
engine, the ignition as well as all electrical components and disconnect the
negative cable (-) on the battery. If you wish to replace a bulb it is sufficient
to switch off the appropriate light.
•Never charge a frozen or thawed battery - risk of explosion and caustic
burns! Replace a frozen battery.
•Never use a battery which is damaged - risk of explosion! Immediately
replace a damaged battery.
Caution
•You must only disconnect the battery if the ignition is switched off, otherwise
the electrical system (electronic compon ents) of the vehicle may be damaged.
When disconnecting the battery from the electrical system of the vehicle, first
disconnect the negative terminal (-) of the battery. Then disconnect the positive
terminal (+).
•When reconnecting the battery, first conne ct the positive terminal (+) and only
then the negative terminal (-) of the ba ttery. You must on no account connect the
cables wrongly - risk of a cable fire.
•Ensure that battery acid does not come into contact with the vehicle body
otherwise damage could occur to the paintwork.
•Do not place the battery in direct dayl ight in order to protect the battery
housing from the effects of ultra-violet light.
For the sake of the environment
A removed battery is a special type of waste which is harmful to the environment -
contact your specialist garage regarding disposing of the battery.
Note
Please also refer to the guidelines ⇒page 235, also after connecting the battery.
Battery with a charge level indicator, the so-called magic eye
There is a so-called magic eye ⇒fig. 216 located on the top of the battery. The
“magic eye” changes its colour in line with the charge state of and electrolyte level
in the battery.
Air bubbles can influence the colour of th e “magic eye”. For this reason carefully
knock on the “magic eye” before carrying out the check.
•Green colour - the battery is adequately charged.
•Dark colour - the battery has to be charged
•Colourless or yellow colour - have th e battery checked by a Škoda dealer.
Batteries, which are more than 5 years old, must be replaced. We recommend you
have the electrolyte level inspected and adju sted to the correct level or the battery
replaced if necessary by a Škoda Service Partner.

A discharged battery may already
freeze at temperatures just below 0°C ⇒. We
recommend that you no longer use a ba ttery which has thawed out because the
casing of the battery may be cracked through the formation of ice and this would
allow battery electrolyte to flow out.
The vent plugs of the battery should not be opened for charging.
WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic
burns. Replace a frozen battery.
Disconnecting and reconnecting the battery
On disconnecting and reconnecting the batte ry the following functions are initially
deactivated or are no longer able to operate fault-free.
We recommend having the ve hicle checked by a Škoda Service Partner to ensure
full functionality of all electrical systems.
Replacing the battery
You should only replace a battery with a new battery of the same capacity, voltage
(12 V), amperage and of the same size. Škoda Service Partners have a range of suit-
able batteries available.
We recommend that you only have an old ba ttery disposed of by your Škoda dealer
since it does require special disposal.
For the sake of the environment
Batteries contain pois onous substances such as sulphur ic acid and lead. They must
be disposed of in accordance with loca l environmental protection regulations and
on no account as domestic waste.
Windshield washer system
The windshield washer reservoir contains the cleaning fluid for the windscreen or
rear window and for the headlamp cleaning system*. The reservoir is located at the
front right of the engine compartment ⇒fig. 217 .
The filling level of the container is 3 litres, 5.5 li tres on vehicles which also have a
headlight washing system.
Clear water is not sufficient to intensivel y clean the windscreen and headlights. We
therefore recommend using clean washing water together with the screen cleaner
from Škoda genuine accessorie s (in winter additionally with antifreeze) which is
capable of removing stubborn dirt. Follow the instructions for use on the packaging
when using screen cleaning products.
You should always add antifreeze to the cleaning water in winter even if your
vehicle is fitted with heated windscreen washer nozzles*.
It is also possible in exceptional cases to use methylated spirits when no screen
cleaner with antifreeze is available. The concentration of methylated spirits must

Wheels and Tyres
Wheels
General information
•New tyres do not offer optimal grip at first and should therefore be run in for
about 500 km at a moderate speed and an appropriately cautious style of driving.
You will also profit from longer tyre life.
•The tread depth of new tyres may differ because of design features and the
configuration of the tread (depending on the type of tyre and the manufacturer).
•Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angles in order to avoid damage to tyres and wheel trims.
•Inspect your tyres from time to time for damage (punctures, cuts, splits and
bulges). Remove foreign bodies from the tyre profile.
•Damage to tyres and wheels is frequent ly not visible. Unusual vibrations or
pulling of the vehicle to one side could be a sign of tyre damage. Please reduce
your speed immediately and stop if you suspect that a wheel is damaged.
Inspect the tyres for signs of damage (bulges, splits, etc.). If no visible damage is
present, please drive at an appropriatel y slow speed and carefully to the nearest
specialist garage in order to have your vehicle inspected.
•Also protect your tyres from contact with oil, grease and fuel.
•Immediately replace any dust caps of the valves which have got lost.
•Mark wheels before removing them so th at their previous direction of running
can be maintained when mounted them again.
•Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not fixed to a wheel trim should be stored
upright.
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of the tyre. This
indicates the direction of rotation of the tyre, and it is essential that the tyres are
fitted on to run in this direction. Only then are the tyres able to provide the optimal
properties in terms of grip, low noise, wear-and-tear and aquaplaning. Further information concerning
the use of unidirectional tyres ⇒page 241.
WARNING
•New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!
•Never drive with damaged tyres - risk of accident!
Note
Please observe the various differing legal requirements regarding tyres.
Tyre life
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insufficiently
or over-inflated and this will have an adverse effect on the handling of your vehicle.
Correctly inflated tyres are of partic ular importance when travelling at high speeds.
It is therefore good to check the pressure at least once a month and also before
