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
Fuel Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data

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

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

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
774 G.
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. Coolant capacity Petrol engines Capacities (in liter)

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. Note
On vehicles which are fitted with an independent auxiliary heating and ventila-
tion, the volume of the coolant is greater by approx. 1 ltr. 184
