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 temper-
ature of -25°C.
Biofuel
We recommend refuelling with diesel fuel at temperatures below -10°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.

•Vehicles fitted with catalytic converter should never 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.
For the sake of the environment
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. You should not
continue refuelling - otherwise the expansion chamber in the fuel tank will
also be filled with fuel. Fuel might flow out of the tank when it heats up.
Emergency release of fuel filler flap
If the electric lock is faulty, you can also unlock the fuel filler flap
manually. – Open the boot lid/luggage compartment door.
– Unscrew the clip attaching the right-hand side trim panel and
pull the trim panel off the body.
– Pull on the loop in direction of arrow in order to unlock the fuel filler flap ⇒fig. 152 .

Working in the en gine 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 st ated 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 compartmen t - risk of scalding! 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 properly after closing the bonnet.
•Stop your vehicle immediately wh ile driving if you notice that
the lock is not properly engaged and close the bonnet properly -
risk of an accident!
WARNING
•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 gear-
shift 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 expansion 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.
•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 also comply with the warning instructions stated below
when carrying 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.

Inspecting and Replenishing209
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 203.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 157. 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 28. We nevertheless
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 Škoda
dealer.
Losses can only occur through the pressure relief in the cap of the coolant
expansion bottle which is completely free of leaks if the coolant boils as a
result of overheating and is forced out of the cooling system.
One should contact a Skoda dealer as soon as possible if the source of
overheating itself cannot be determined and removed, since there may be
grave damage 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
⇒page 208, fig. 157 and unscrew the cap carefully by
turning it to the left ⇒.
– Top up the coolant.
– Screw on the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with
certain specifications ⇒page 208, “Coolant”. Do not use an alternative
additive if the coolant additive G12°PLUS 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 Škoda dealer.
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 coolant 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 damage.
Do not continue your journey if for some reason it is not possible
under the conditions prevailing to top up with coolant. Switch off the
engine and obtain professional assistance from a Škoda dealer.
WARNING
•The cooling system is pressurized! Do not open the cap of the
coolant expansion bottle if the engine is still hot - risk of
scalding!

Wheels and Tyres225
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
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 essen-
tial 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.
Should it be necessary to fit on a spare wheel in exceptional cases with a
tyre not dedicated to the running direction, please adopt a cautious style
of driving as the tyre is no longer able to provide optimal grip and handling
in such a situation. This particularly important on wet roads. Please refer
to the notes ⇒page 229.
You should have the defective tyre replaced as soon as possible and
restore the correct direction of rotation on all tyres
Snow chains
Snow chains can be used only for wheel sizes 6J x 16 ET 40 or 6J x 16
ET 37. Your Škoda Dealer can provide you with more detailed information.
Snow chains must only be mounted on the front wheels.
When driving on wintry roads, snow chains improve not only traction, but
also the braking performance.
Only use fine-link snow chains . They must not project more than 15 mm
- including the chain lock.
Remove the full wheel trim if you wish to fit snow chains to the wheels.
You must take the chains off as soon as you drive on roads which are free
of snow. They adversely affect the handling of your vehicle, damage the
tyres and are rapidly destroyed. Observe the national legal requirements relating to the maximum vehicle
speed with snow chains.
Note
We recommend that you use snow chains from the Škoda range of
genuine accessories.
