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 the car for a lengthy period, fill with petrol complying with (DIN)
EN°228, because Ethanol E85 can contain lo w quantities of impurities, which can
lead to corrosion.
For the sake of the environment
If you use Ethanol E85, the CO2 emission of your vehicl e 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 unleaded
petrol.
•Biofuel Ethanol E85 contains only a low quantity of additives in contrast to
unleaded 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 222, “Refuelling”.
•The interval of 15 000 km applies for the oil change.
Operation in winter
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. 205 .
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 Etha nol 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.
For the sake of the environment
The use of engine preheating at temperatures below -10°C has a positive effect on
the fuel consumption and thus on the environment.
The outside temperatureDuration of engine preheating
lower than -10 °Cwe recommend up to 1 hour
lower than -15 °Cat least 1 hour
lower than -25 °Cat least 2 hour

Inspecting and replenishing
228
Replenishing engine oil
– Inspecting the engine oil level ⇒page 227.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 272,
“Engine oil specifications”.
– Inspect the oil level ⇒page 227.
– 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 225, “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 ⇒page 227. Oil will
otherwise be drawn in through the crankc ase ventilation and may pass through the
exhaust system to atmosphere. The oil ma y 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 20, “Service Interval Display”.
WARNING
•Only carry out the engine oil change, if you have the required profes-
sional knowledge!
•Read and observe the warning notes ⇒page 225, “Working in the engine
compartment” before working in the engine compartment.
•Let the engine cool down - risk of burning from hot oil.
•Wear an eye protection - risk of caustic burns due to oil splashes.
•Oil is toxic! Store old oil in a safe place out of the reach of children and
unauthorized persons until you dispose of it properly.
Caution
You must not pour any additives into th e engine oil - risk of engine damage!
Damage, which results from such produc t, 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 prop erly disposing of old oil, the material,
equipment and the knowledge required fo r such work, we recommend that you
have the oil and oil filter change carr ied out by your Škoda Service Partner.
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 an y maintenance under normal operating
conditions. The coolant consis ts 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 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.
