Underbody protectionThe underside of your vehicle is protected for life against chemical and mechanical
influences.
One cannot, however, completely rule out damage to the protective layer when
driving so we recommend that you inspect the protective layer on the underside of
your vehicle and on the chassis at certain intervals - this is best done at the beginning
and end of the winter - and to touch up any damaged areas.
The authorised Škoda Service Partners have suitable spray products available as well
as the necessary equipment and are familiar with the instructions for use. It is therefore
best to have such touch-up work or additional corrosion protection measures carried
out by an authorised Škoda Service Partner.
WARNING
Never use additional underbody protection or corrosion-protection agents for
the exhaust pipes, catalytic converters, di esel particle filter or heat shields.
When the engine reaches its operating temperature, these substances might
ignite - risk of fire!Protection of hollow spacesAll the cavities of your vehicle which are at risk from corrosion are protected for life by
a layer of protective wax applied in the factory.
This wax protection does not require to be inspected or re-treated. Please remove any
small amount of wax which flows out of the cavities at high temperatures with a plastic
scraper and clean the spot using petroleum cleaner.
WARNING
Safety and environmental pr otection regulations should observed when using
petroleum cleaner to remove wax - a risk of fire!
Engine compartmentGood corrosion protection is very importan t, particularly in winter when one often
drives over its salt-strewn roads. One should therefore clean the whole engine
compartment before and after the salt spreading period and treat with preservative in
order to prevent the salt from being destructive.
The authorised Škoda Service Partners have the cleaning agents and preservatives
recommended by the manufacturer and also the required equipment.
WARNING

It is necessary to observ e the guidelines given in the chapter before working
on the engine compartment page 197, “Working in the engine compart-
ment”.

Let the engine cool down before cleaning the engine compartment.Caution

Engine cleaning may be only be un dertaken when the ignition is off.

It is recommended to cover the generator before washing the engine compart-
ment.For the sake of the environment
The dirty water produced by washing the engine has washed away petrol, and residues
of grease and oil and should therefore be cleaned by an oil separator. This is why
engine washing should only be undertaken in a specialist garage or at a fueling station
(when these are fitted with the required equipment).Care of the interior of vehiclePlastic parts, artificial leather and clothsYou can clean plastic parts and artificial leather with a moist cloth. You should only
treat such parts with special solvent-free plastic cleaning and care products it does
prove to be adequate.

Fuel
192
FuelPetrolGrades of petrolYour vehicle can only be operated with unleaded petrol, which complies with the
standard EN 228. The individual grades of petrol are distinguished by their octane
number (RON). On the inside of the fuel filler flap, you will find the information
regarding the RON required by your engine page 195, fig. 159 - right.
Prescribed fuel - unleaded petrol 95/91 RON
Use unleaded petrol 95 RON. You can also use unleaded petrol 91 RON, but this leads
to a slight loss in performance.
If, in case of necessity, the vehicle must be refuelled with petrol of a lower octane
number than the one prescribed, you must co ntinue driving at medium engine speeds
and low engine load. Driving at high engine speeds or a high engine load can severely
damage the engine! Refuel as soon as possib le with petrol of the prescribed octane
number.
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded petrol 95 RON.
In case of necessity, you can refuel with petrol 91 RON if petrol 95 RON is not avail-
able. You must continue driving at medium engine speeds and minimum engine load.
Driving at high engine speeds or a high engine load can severely damage the engine!
Refuel as soon as possib le with petrol of the prescribed octane number.
Even in case of necessity, you must not use petrol of a lower octane number than 91,
otherwise the engine can be severely damaged!
You can find further information on refuelling page 195, “Refuelling”.
Unleaded petrol with higher octane number
You can make unlimited use of unleaded pe trol which has a higher octane number
than the one prescribed. On vehicles with prescribed unleaded petrol
95/91 RON, the use of petrol with a
higher octane number than 95 does not result in a noticeable power increase or a
lower fuel consumption.
On vehicles with prescribed unleaded petrol min. 95 RON, the use of petrol with a
higher octane number than 95 does not result in a power increase or a lower fuel
consumption.
Caution

All Škoda vehicles with petrol engines are equipped with a catalytic converter and
must be only driven with unleaded petrol. Fi lling the tank even only once with leaded
petrol will result in the cata lytic converter being destroyed!

Only use unleaded petrol which complies with the standard EN 228.

If you use petrol with a lower octane num ber than the one prescribed, the engine
can be severely damaged!
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 complying
with the standard (DIN) EN°228.
Biofuel Ethanol E85 in accordance with th e standard (DIN) EN 228 can be mixed in any
desired ratio with unleaded petrol, see Owner's Manual.
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 the car for a lengthy period, fill with petrol complying with (DIN) EN°228,
because Ethanol E85 can contai n low quantities of impurities, which can lead to corro-
sion.For the sake of the environment
If you use Ethanol E85, the CO
2 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 195, “Refuelling”.

The interval of 15 000 km applies for the oil change.
Operation in winterIf 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. 158.
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 p oor 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 temperature

Fuel
194Note
An extension cable used for connecting to the electrical network is located in the
luggage compartment.DieselDiesel fuelYour vehicle can only be operated with diesel fuel, which complies with the standard
EN 590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in Austria).
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and similar prod-
ucts) in diesel fuel.
You can find information on refuelling page 195, “Refuelling”.
Caution

Therefore, your vehicle can only be operated with diesel fuel which complies with
the standard EN 590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in
Austria). Filling the tank even only once wi th diesel fuel which does not comply with
the standard, can result in damage to the engine parts, the lubrication system, the fuel
and exhaust system.

If by mistake you have refuelled with a different fuel other than the diesel fuel
which complies to the above mentioned standards (e.g. petrol), do not start the engine
or switch on the ignition! This can result in severe engine damage! Contact a specialist
garage and have the fuel sy stem of the engine cleaned.

Water which has collected in the fuel fi lter can result in engine problems.

Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must not be
refuelled and driven. The use of biofuel (RME) can lead to damage to the engine or the
fuel system.
Operation in winterWinter-grade diesel fuel
A different grade of diesel fuel is available at filling stations in winter than during the
summer. Using “summer-grade diesel fuel” at temperatures below 0°C can result in
operational problems because the diesel beco mes viscous as a result of paraffin sepa-
ration.
It is therefore the case that the standard EN 590 (standard DIN 51628 in Germany,
standard ÖNORM C 1590 in Austria) is the diesel fu el class prescribed for certain
periods of the year which can also be purc hased at the corresponding time during the
year. “Winter-grade diesel fuel” will still operate properly even at a temperature of -
20°C.
It is often the case in countri es with different climatic conditions that diesel fuels avail-
able have a different temperature characteristic. The authorised Škoda Service Part-
ners and filling stations in the country conc erned will be able to provide you with infor-
mation regarding the diesel fuels available.
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 temperature of -25°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.

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 th e paintwork of your vehicle immediately
- risk of paint damage!

On vehicles fitted with a ca talytic converter, never let the fuel tank 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.

Make sure that the valve is not pressed into the filler tube when inserting the pump
nozzle into the filler tube. Otherwise you ar e 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 - other-
wise the expansion volume is filled up.
