Press the fuel tank flap closed.
The correct grade of fuel for your vehicle as well as the tyre size and inflation
pressures are stated on a sticker affixed to the inside of the fuel filler flap. Further
information on fuel ⇒
page 147.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
● 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.
● Make sure that the valve is not pressed into the filler tube when inserting the
pump nozzle into the filler tube. Otherwise 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.
● 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. Note
The fuel tank has a capacity of about 55 litres, containing a reserve of 7 litres. 149

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.
● 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! WARNING (Continued)
● 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!

6 Oil level within range
a –
You must not top up the oil.
Oil level within range b –
You may top up the oil. It is possible that the oil level may then be within
range a after doing this. The optimum lies in the middle of the range
b .
Oil level within range c –
You must top up the oil ⇒ page 152. It is sufficient, once this is done, to keep
the oil level is within range b .
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 b 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 whether the oil level is
too low ⇒ page 23,
Engine oil . 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

Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒ page 194 .
– Inspect the oil level ⇒ page 152.
– 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 150, 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 a ⇒ page 152. Oil will other-
wise be drawn in through the crankcase ventilation and may pass through the ex-
haust 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. WARNING
● Only carry out the engine oil change, if you have the required professional
knowledge!
● Read and observe the warning notes ⇒
page 150, 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
ŠKODA Service Part-
ner. Note
After your skin has come in contact with the oil, you must thoroughly wash your
skin.
Cooling system
Coolant The job of the coolant is to cool the engine.
The cooling system does not require any maintenance under normal operating
conditions. The coolant consists of water with a concentration of coolant additive
of 40 %. This mixture not only provides antifreeze protection down to -25 °C but
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 concentration of antifreeze agent in the cool-
ant by adding water, also not during the summer 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 pro-
tection down to approx. -40 °C). The antifreeze protection tails off above that con-
centration.
Vehicles exported to countries with a cold climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant which offers antifreeze protection down
to about -35 °C. In these countries the concentration of coolant additive should be
at least 50 %.
Coolant
The cooling system is factory-filled with coolant (purple in colour), which complies
with the specification TL-VW

When refilling, we only recommend you use the same antifreeze described on the
antifreeze expansion tank.
Please contact an authorised
ŠKODA Service Partner if you have any questions re-
garding the coolant or if you wish to fill up with a different coolant.
An authorised ŠKODA Service Partner can also supply you with the correct coolant
additives.

CAUTION
● Other coolant additives may cause operational problems which, in particular,
involves significantly reducing the anticorrosion effect.
● Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequence of this, result in major engine damage. Inspecting the coolant level Fig. 125 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 ⇒ in Working in the engine compartment on page 151.
– Check the level of coolant in the coolant expansion bottle ⇒ fig. 125 . The cool-
ant level when the engine is cold must lie between the
“MIN” B and “MAX”
A 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 23. 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 150
, Working in the engine com-
partment before working in the engine compartment. £154
Inspecting and Replenishing
Page 157 of 212
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. 125 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 153, Coolant. Do not use an alternative additive if the
specified coolant additive is not available in exceptional cases. Just top up the sys-
tem 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 up over the
“MAX” marking! Excess coolant which is heated up is forced
out of the cooling system through the pressure relief valve in the cap of the cool-
ant compensation bottle.
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! WARNING (Continued)
● If any splashes of coolant get into your eyes, rinse out your eyes immedi-
ately with clear water and contact a doctor as soon as possible.
● You should also consult a doctor without delay if you have inadvertently
swallowed coolant. CAUTION
Do not continue your journey if for some reason it is not possible under the condi-
tions prevailing to top up with coolant. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe en-
gine damage. For the sake of the environment
Do not re-use coolant if it is necessary to drain the coolant in the system. It should
be collected and disposed of in compliance with environmental protection regula-
tions.
Radiator fan The radiator fan may switch on suddenly.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
The radiator fan may continue running for 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 has 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 working in the engine compartment that
the fan may switch on suddenly - risk of injury! 155

Brake fluid
Inspecting the brake fluid level Fig. 126 Engine compartment: Brake
fluid reservoir
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 ⇒ in Working in the engine compartment on page 151.
– Inspect the brake fluid level in the reservoir ⇒ fig. 126 . The level must be be-
tween 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 brake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid lev-
el 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 lighting up
in the instrument cluster ⇒ page 26. In this case stop immediately and do not
drive any further! Contact a Škoda dealer to obtain professional assistance. WARNING
● Read and observe the warning notes ⇒
page 150, 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 fur-
ther - risk of accident! Contact a Škoda dealer to obtain professional assis-
tance. 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 501 14,
● 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. £156

– The installation of the battery cover on the positive terminal side takes place
in the reverse order.
Battery control Fig. 128 The battery: Electrolyte level
indicator
The battery is practically maintenance-free under normal operating conditions. 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 159.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called mag-
ic eye ⇒ fig. 128 , 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 the winter, and recharged if necessary. WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic burns.
Replace a frozen battery. 158

Charging the battery
A properly charged battery is essential for reliably starting the en-
gine.
– Read the warning notes ⇒ in General information on page 157 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 157.
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. WARNING
● Never charge a frozen or thawed battery - risk of explosion and caustic
burns. Replace a frozen battery.
● Never charge a battery which has a too low electrolyte level - risk of explo-
sion and caustic burns. CAUTION
On vehicles with the “START/STOP” system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth ⇒ fig. 143.
Disconnecting and reconnecting the battery On disconnecting and reconnecting the battery the following functions are initially
deactivated or are no longer able to operate fault-free.
