Biofuel Ethanol E85
Ethanol E85 Only valid for vehicles with 1.6/75°kW MultiFuel engine.
Biofuel Ethanol E85 consists of 85 % bioethanol and 15 % unleaded petrol com-
plying with the standard (DIN) EN°228.
Biofuel Ethanol E85 in accordance with the standard (DIN) EN 228 can be mixed in
any desired ratio with unleaded petrol.
Drive the vehicle for at least 5 minutes without interruption, if biofuel Ethanol E85
has been refuelled, so that the engine control 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 damaged in the event of an accident and
fuel may leak out. CAUTION
● Even inadvertently filling the fuel tank with another biofuel such as Ethanol
°E85 can result in damage to the fuel system.
● If you park your vehicle for a lengthy period, fill with petrol complying with
(DIN) EN°228, because Ethanol E85 can contain low quantities of impurities, which
can lead to corrosion. For the sake of the environment
If you use Ethanol E85, the CO 2 emission of your vehicle is lowered up to 5 %. Note
● When operating with Ethanol E85, the fuel consumption increases by approx
33 %, as a lower quantity of energy is contained in the bioethanol than in unlea-
ded petrol.
● Biofuel Ethanol E85 contains only a low quantity of additives in contrast to un-
leaded petrol. Therefore we recommend to fill up the tank with unleaded petrol
complying with EN 228 every 15 000 km (e.g. before the oil change) and run it
empty, so that the engine remains clean. Make sure not to use the whole content
of the tank ⇒ page 178, Refuelling
.
● The interval of 15 000 km applies for the oil change.
Operation in winter Fig. 146 MultiFuel - power socket
If you use biofuel Ethanol E85 at very low temperatures, it is necessary to preheat
the engine before an engine start.
The power socket for the engine preheating is located in the front bumper next to
the fog light ⇒
fig. 146 . The outside temperature Duration of engine preheating
lower than -10
℃ We recommend up to 1 hour
lower than -15
℃ at least 1 hours.
lower than -25
℃ at least 2 hours.
If an engine preheating is not possible at outside temperatures lower than -10 °C,
the share of unleaded petrol complying with EN 228 must be as high as possible.
Thus the cold start property of the engine is clearly improved.
If there is biofuel Ethanol E85 in the tank and the engine is not preheated, it can
lead at temperatures below -15 °C to very poor or no starting of the engine. £ 177

pressures are stated on a sticker affixed to the inside of the fuel filler flap. Further
information on fuel ⇒
page 176.
The fuel tank has a capacity of about 55 litres or 60 litres 1)
. 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
● Before refuelling it is necessary to switch off the auxiliary heating system
(auxiliary heating and ventilation).
● Remove any fuel which has spilled onto the paintwork of your vehicle immedi-
ately - risk of paint damage! ●
On vehicles fitted with a catalytic converter, never let the fuel tank run com-
pletely 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.
● The fuel tank is full just as soon as the 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. 1)
Valid for Octavia Combi 4x4 and Octavia Scout. 179

Working in the engine compartment
Particular care is required when carrying out any work in the en-
gine compartment!
There is a risk of injuries, scalding, accidents and fire when working in the en-
gine 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 compartment 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 scalding! 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 in-
to Neutral, or if it is fitted with automatic gearbox, move the selector lever in-
to position
P.
● Allow the engine to cool down.
● Keep children clear of the engine compartment.
● Do not touch any hot engine parts - risk of burns!
● Never spill oil and other fluids over the hot engine. Such fluids (e.g. the an-
tifreeze 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 expansion reservoir so long as the en-
gine is still warm. The cooling system is pressurized!
● Cover over the cap of the 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 com-
partment. WARNING (Continued)
● 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 en-
gine 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:
–Never touch the electrical cables of the ignition system.
– Absolutely avoid any jewellery, loose items of clothing or long hair from
getting into the rotating parts of the engine - Hazard! Therefore remove
any jewellery beforehand, tie up your hair and wear tight fitting clothing.
● Please also comply with the warning instructions stated below when car-
rying out any essential work on the fuel system or on the electrical system.
–Always separate the car battery from the electrical system.
– Do not smoke.
– Never carry out any work close to naked flames.
– Always keep a working fire extinguisher at hand. CAUTION
When replenishing fluids in the engine, always ensure that the fluids are on no ac-
count mixed up. This may result in major operating problems and also vehicle
damage! 181

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 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 A - but not above this
,
if the engine has been operating at high loads, for example during a lengthy mo-
torway trip during the summer months, towing a trailer or negotiating a high
mountain pass.
The warning light in the instrument cluster will indicate whether the oil level is
too low ⇒ page 25, Engine oil pressure . 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 extend beyond the range A . Danger of dam-
aging 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 profes-
sional assistance from a specialist garage, otherwise it could lead to severe en-
gine damage. Note
Engine oil specifications ⇒ page 221, Technical data.
Replenishing engine oil –
Inspecting the engine oil level ⇒
page 182.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒ page 224, Engine oil
specifications.
– Inspect the oil level ⇒ page 182
.
– 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 181, Working in the engine
compartment before working in the engine compartment. For the sake of the environment
The oil level must on no account extend beyond the range A ⇒
page 182. Oil will
otherwise be drawn in through the crankcase ventilation and may pass through
the exhaust system to atmosphere. The oil may combust in the catalytic converter
and damage it.
Changing engine oil The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator
⇒ page 12, Service reminder indicator
. WARNING
● Only carry out the engine oil change, if you have the required professional
knowledge!
● Read and observe the warning notes ⇒
page 181, Working in the engine
compartment before working in the engine compartment.
● First of all, let the engine cool down, wear an eye protection and gloves -
risk of caustic burns due to hot oil. CAUTION
You must not pour any additives into the engine oil - risk of engine damage! Dam-
age, 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 properly 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

Inspecting the coolant level
Fig. 152 Engine compartment: Coolant
expansion bottle
The coolant expansion bottle is located in the engine compartment on the right.
– Switch the engine off.
– Open the bonnet ⇒ page 180 .
– Check the level of coolant in the coolant expansion bottle ⇒ fig. 152 . The cool-
ant level when the engine is cold must lie between the b (MIN) and
a (MAX)
markings. The level may also rise slightly above the a (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 25, Coolant temperature/ Coolant quantity
. We
still recommend inspecting 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.
Losses can only occur through the pressure relief in the cap of the coolant expan-
sion bottle which is completely free of leaks if the coolant boils as a result of over-
heating and is forced out of the cooling system. WARNING
Read and observe the warning notes ⇒ page 181, Working in the engine com-
partment
before working in the engine compartment. CAUTION
One should contact a specialist garage as soon as possible if the source of over-
heating itself cannot be determined and removed, since there may be grave dam-
age to the engine.
Replenishing the coolant –
Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir ⇒
fig. 152 and un-
screw the cap carefully by turning it to the left ⇒ .
– Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with one
specific specification ⇒ page 184
. Do not use an alternative additive if the speci-
fied coolant additive is not available in exceptional cases. Just top up the system
with water and as soon as possible arrange adjustment to correct the mixing ratio
of water and coolant additive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill the coolant above the mark a (max.)
⇒ fig. 152 ! Excess coolant heats up
and then is forced out of the cooling system through the pressure relief valve in
the cap.
Wait until the engine has cooled down for a system which has suffered a major
loss of coolant before pouring in coolant. This is necessary to avoid engine dam-
age. WARNING
● The cooling system is pressurized! Do not open the cap of the coolant ex-
pansion bottle if the engine is still hot - risk of scalding!
● The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the
health. It is important, therefore, to always safely store any coolant additive in
its original container out of the reach of children - risk of poisoning! £ 185

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. The water content also lowers the
boiling point of the brake fluid.
Only new genuine brake fluid from
ŠKODA may be used.
The brake fluid must comply with one of the following standards or specifications:
● VW 50114
● FMVSS 116 DOT4
● DIN ISO 4925 CLASS 4
We recommend that you have the brake fluid replaced by an authorised ŠKODA
Service Partner as part of an Inspection Service. WARNING
Using old brake fluid can result in severe stress on the brakes because of the
formation of vapour bubbles in the brake system. This greatly impairs the
braking efficiency and thus also the safety of your vehicle. CAUTION
Brake fluid damages the paintwork of the vehicle. For the sake of the environment
Due to issues with disposal, the special tools and knowledge required, we recom-
mend you have the brake fluid replaced by an authorised ŠKODA Service Partner.
Battery General information Improper handling of the vehicle battery can cause damage. We therefore recom-
mend you have work on the vehicle battery carried out by an authorised
ŠKODA
service partner. There is a risk of injuries, scalding, accidents and burns when carrying out any
work on the battery and on the electrical system. For this reason, it is essential to
comply with the warning instructions ⇒ stated below and with the general ap-
plicable rules of safety. WARNING
● The battery acid is strongly corrosive and must, therefore, be handled with
the greatest of care. Always wear protective gloves, eye and skin protection
when handling batteries. Corrosive fumes in the air irritate the air passages
and lead to conjunctivitis and inflammation of the air passages in the lungs.
Battery acid corrodes dental enamel and creates deep wounds after contact
with the skin which take a long time to heal. Repeated contact with diluted
acids causes skin diseases (inflammations, ulcers, slin cracks). Acids coming in-
to contact with water are diluted accompanied by significant development of
heat.
● Do not tilt the battery otherwise battery electrolyte may flow out of the
battery vent openings. Protect the eyes with safety glasses or a shield! There
is the danger of suffering blindness! If any battery electrolyte gets into your
eye, rinse out your eye immediately with clear water for several minutes. Con-
tact a doctor without delay.
● Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. If acid was
swallowed, seek immediate medical attention.
● Keep batteries out of the reach of children.
● Hydrogen is released when you charge a battery and a highly explosive gas
mixture is produced. An explosion can be caused through sparkling over dur-
ing 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, explo-
sion 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 devices. Strong sparking represents a risk of injury.
● Before carrying out any work on the electrical system, switch off the en-
gine, the ignition as well as all electrical components and disconnect the neg-
ative cable (-) on the battery. If you wish to replace a bulb it is sufficient to
switch off the appropriate light. £ 187

We recommend you have the electrolyte level checked by a specialist garage from
time to time, especially in the following cases.
● High outside temperatures.
● Long daily drives
● After each charge ⇒ page 189.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called mag-
ic eye ⇒ fig. 155 , the electrolyte level can be determined by looking at the change
in colour.
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
● Black colour - electrolyte level is correct.
● Colourless or light yellow colour - electrolyte level too low, the battery must be
replaced. Note
● The battery electrolyte level is periodically checked by an authorised
ŠKODA
Service Partner as part of the Inspection Service.
● For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked.
● Vehicles with a “START-STOP” system are fitted with a battery control unit for
checking the energy level for the recurring engine start.
Operation in winter The battery has to provide greater amounts of electricity during the winter. It also
has only part of the initial power output at low temperatures that it has at normal
temperatures.
A discharged battery may already freeze at temperatures just below 0 °C.
We therefore recommend that you have the battery checked by a specialist ga-
rage before the start of winter and recharged if necessary. WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic burns.
Replace a frozen battery. Charging the battery A properly charged battery is essential for reliably starting the en-
gine.
– Read the warning notes ⇒
in General information on page 187 and ⇒
.
– Switch the ignition and all electrical components off.
– Only for “quick-charging”: Disconnect both battery cables (first of all “nega-
tive
”, then “positive”).
– Carefully attach the terminal clamps of the charger to the battery terminals
(red = “positive
”, black = “negative”).
– You can now plug the mains cable of the charger into the power socket and
switch on the charger.
– When charging is completed: switch the charger off and unplug the mains ca-
ble from the power socket.
– Only then should you disconnect the terminal clamps of the charger.
– Reconnect the cables to the battery (first of all “positive”, then “negative”).
It is not normally necessary to disconnect the cables of the battery if you recharge
the battery using low amperages (as for example from a mini-charger). Please al-
so refer to the instructions from the charger manufacturer.
A charging current of 0.1 of the total battery capacity (or lower) is that which
should be used until full charging is achieved.
It is, however, necessary to disconnect both cables before charging the battery
with high amperages, so-called
“quick-charging ”.
“Quick-charging” a battery is dangerous ⇒ in General information on page 187.
It requires a special charger and specialist knowledge. We recommend having the
quick charging of vehicle batteries undertaken by a specialist garage.
A discharged battery may already freeze at temperatures just below 0
°C ⇒ . We
recommend that you no longer use a battery 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. £ 189

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. 156 .
The filling level of the container is about 3 litres and about 5.5 litres on vehicles
which have a headlight washing system.
Clear water is not sufficient to intensively clean the windscreen and headlights.
We therefore recommend using clean washing water together with the screen
cleaner from ŠKODA Original Accessories (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 ve-
hicle 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
not be more than 15 %. Please note, however, that the antifreeze protection at
this concentration is only adequate down to -5 °C. WARNING
Read and observe the warning notes ⇒ page 181, Working in the engine com-
partment
before working in the engine compartment. CAUTION
● On no account should you add radiator antifreeze or other additives to the
windscreen washer fluid.
● If the vehicle is fitted with a headlight cleaning system, you should only add
cleaning products which do not attack the polycarbonate coating of the head-
lights to the windscreen washer fluid. Please contact an authorised
ŠKODA Serv-
ice Partner who will help you select a suitable cleaning agent. 191

The tyre inflation pressure for tyres of the tyre size 205/50 R17, which are inten-
ded to be used with snow chains, is identical to the tyre inflation pressure for
tyres of the tyre size 225/45
R17, see ⇒ fig. 157.
The tyre pressure should be at the highest pressure specified for your vehicle at
all times.
The tyre inflation pressure of the emergency spare wheel R 18 is 420 kPa
(4.2 bar).
Always check the inflation pressure of tyres when cold. Do not reduce the higher
pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if
your vehicle is carrying a significantly higher payload.
Driving style
Fast cornering, sharp acceleration and braking (squealing tyres) increase wear-
and-tear on your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences
when driving which may result in an imbalance and which makes themselves felt
through vibration in the steering.
You should have the wheels rebalanced since any imbalance increases wear-and-
tear on the steering, the suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted and each time a tyre is repaired.
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-and-
tear on the tyres but will also has an adverse effect on vehicle safety. Contact
your specialist garage if you notice any unusual tyre wear. WARNING
● If the inflation pressure is too low, the tyre must perform a higher rolling
resistance. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and even a tyre blowout.
● Immediately replace the damaged rims or tyres.
● Tyres which are 6 years old or more should only be fitted in exceptional ca-
ses and when adopting an appropriately cautious style of driving. For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption. Wear indicators
Fig. 158 Tyre tread with wear indicators
The base of the tread of the original tyres has wear indicators 1.6 mm high, instal-
led at right angles to the direction of travel. These wear indicators are located at 6
- 8 points depending on the make and are evenly spaced around the circumfer-
ence of the tyre ⇒ fig. 158 . Markings on the walls of the tyres through the letters
“TWI”, triangular symbols or other symbols identify the position of the wear indi-
cators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the
wear indicators, means that your tyres have reached their legally permissible mini-
mum tread depth. WARNING
● You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn down. The legally permissible minimum tread
depth should be observed.
● Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience “
aquaplaning” (uncontrolled
movements of the vehicle - “swimming” on a wet road surface). 193
Wheels and Tyres Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data
Page 197 of 248
WARNING
● Only use those tyres or wheel rims which have been approved for your
model of ŠKODA vehicle. Failure to observe this instruction will adversely af-
fect the road safety of your vehicle - risk of accident! Approval and licensing of
your vehicle on public roads may also become void as a result.
● You must on no account drive at a higher speed than is permissible for
your tyres - risk of an accident resulting from tyre damage and loss of control
over your vehicle.
● Tyres which are 6 years old or more should only be fitted in exceptional ca-
ses and when adopting an appropriately cautious style of driving.
● Never fit tyres which have already been used without having adequate
knowledge of their previous history. Tyres age even if they have not been
used at all or only very little. A spare tyre must only be used in exceptional ca-
ses and only then when adopting an appropriately cautious style of driving.
● Do not, where possible, replace individual tyres but at least replace them
on both wheels of a given axle at the same time. Always fit the tyres with the
deeper tread depth to the front wheels. For the sake of the environment
Old tyres must be disposed of in conformity with the appropriate regulations. Note
It is not normally possible to fit wheels from other models of cars for technical
reasons. This may also apply in certain circumstances to the wheels of the same
type of vehicle.
Wheel bolts Wheels and
wheel bolts are matched to each other in terms of design. Each time
you fit other wheels - e.g. light alloy wheels or wheels with winter tyres - you
must therefore also use the matching wheel bolts of the correct length and shape
of spherical cap. This is essential to ensure that the wheels are tightly fitted and
that the brake system operates properly.
If you retrofit wheel trims (or have this done), please also ensure that an ade-
quate flow of air remains assured for cooling the brake system.
Authorised
ŠKODA Service Partners are instructed in the technical possibilities
which exist regarding converting or retrofitting tyres, wheels and wheel trims. WARNING
● In case of incorrect treatment of the wheel bolts, the wheel can loosen
when the car is moving - risk of accident!
● The wheel bolts must be clean and must turn easily. However, they must
never be treated with grease or oil.
● If the wheel bolts are tightened to a too low tightening torque, the rim can
come loose when the car is moving - risk of accident! A tightening torque
which is too high can damage the bolts and threads and this can result in per-
manent deformation of the contact surfaces on the rim. CAUTION
The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
Winter tyres The handling of your vehicle will be significantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber
blend, tread pattern). This particularly applies to vehicles which are equipped with
low-profile tyres
or high-speed tyres (code index H or V on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best handling
characteristics.
You must only fit those types of winter tyre which are approved for your vehicle.
The permissible sizes of winter tyres are stated in your vehicle documents. Ap-
provals may differ because of national legislation.
Please remember that the tyres should be inflated to 20
kPa (0.2 bar) more than is
the case for summer tyres ⇒ page 192.
Winter tyres no longer offer the same winter performance once the tyre tread has
worn down to a depth of about 4 mm.
Ageing also causes winter tyres to lose most of their winter performance proper-
ties - even in cases where the remaining tread depth is still clearly more than 4
mm.
Speed restrictions apply to winter tyres as well as to summer tyres ⇒ page 194,
⇒ .
