Protection of hollow spacesFirst read and observe the introductory information and safety warn-
ings
on page 159.
All 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.
Wax protection does not require to be inspected or re-treated. If any small amount of wax flow out of the cavities at high temperatures, these must be re-
moved with a plastic scraper and the stains cleaned using a petroleum cleaner.
WARNINGSafety regulations should be observed when using petroleum cleaner to re-
move wax – risk of fire!

Artificial leather, cloths and Alcantara ®
First read and observe the introductory information and safety warn- ings
on page 159.
The artificial leather can be cleaned using a damp cloth. If this does not prove suf-
ficient, only use cleaning agents designed specifically for this purpose.
Dust and fine dirt particles in pores, creases and seams may chafe and damagethe surface. If you leave your vehicle parked in the open for lengthy periods, pro-
tect the Alcantara ®
seat covers from the direct rays of the sun to prevent fading.
Minor changes in colour caused by use are normal.
Clean upholstery cover materials and cloth trims on doors, luggage compartment
cover, etc. using specific cleaning agents, e.g., dry foam. Use a soft sponge, brush,
or commercially available microfibre cloth. Use a cloth and a specific cleaning
agent to clean the roof trim.
Some clothing materials, such as dark denim, do, in part, not have sufficient col-
our fastness. This can cause damage or clearly visible discolouration to seat cov-
ers (fabric or leather) even when used correctly. This particularly applies to light
seat covers (fabric or leather). This is not a defect in the seat cover, but poor col-
our fastness of the clothing textiles.
CAUTIONDo not use any leather cleaners on Alcantara ®
seat covers.
Fabric covers on electrically heated seats
First read and observe the introductory information and safety warn-
ings
on page 159.
Do not clean the seat covers using moisture as this can damage the seat heating
system.
Use a specific cleaning agent such as dry foam or similar to clean the covers.

Natural leather
First read and observe the introductory information and safety warn-
ings
on page 159.
Depending on the amount of wear-and-tear, the leather should be cleaned on a
regular basis.
Normal cleaning
Clean soiled areas of the leather with slightly moistened cotton or woollen cloth.
Severe soiling
Ensure that the leather is not soaked through at any point and that no water gets
into the stitching of the seams.
Dry off the leather with a soft, dry cloth.
Removing stains
Remove fresh water-based stains (e.g., coffee, tea, juices, blood) with an absorb-
ent cloth or household cleaning paper. A specific cleaning agent is required for
dried-on stains.
Remove fresh grease-based stains (e.g. butter, mayonnaise, chocolate, etc.) with
an absorbent cloth, household cleaning paper, or use a suitable cleaner if the
stain has not yet penetrated into the surface.
Use a grease solvent to remove grease stains which have dried in .
Remove specific stains (e.g. ball-point pens, marker pen, nail varnish, dispersion
paint, shoe polish, etc.) with a special stain remover suitable for leather. 
164General Maintenance

›Hold the fuel filler cap on the fuel filler tube with one hand and lock it by turn-
ing the vehicle key to the right and remove the key.›
Close the fuel filler flap until it clicks into place.
›
Check that the fuel filler flap is closed properly.
Incorrect refuelling guard on vehicles with diesel engines The fuel filler tube on vehicles with diesel engines has been fitted with a incor-
rect refuelling guard » Fig. 145. This guard means it is only possible to refuel with
the diesel pump nozzle.
If the diesel pump nozzle does not sit directly in the fuel filler tube, move it to and fro with slight pressure to insert it correctly.
CAUTION
■ 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 filling the fuel tank otherwise the expansion volume is filled up.■
Before refuelling, switch off the auxiliary heating system (auxiliary heating and
ventilation).
■
Be careful when filling diesel fuel from the spare canister - danger of contami-
nating the body.
Note
The fuel tank has a capacity of about 50 litres, containing a reserve of approx.
7 litres .
Unleaded petrol
First read and observe the introductory information and safety warn-
ings
on page 167.
Your vehicle can only be operated with unleaded fuel that complies with the
standard EN 228 (in Germany: standard DIN 51626-1 or E10 for unleaded fuel with
an octane rating of 95 RON and 91 RON or DIN 51626-2 or E5 for unleaded fuel
with the octane rating 95 RON and 98 RON).
Prescribed fuel – unleaded fuel 95/91 RON Use unleaded fuel with the octane rating 95 RON. Unleaded petrol 91 RON can al-
so be used but results in a slight loss in performance.
Prescribed fuel – unleaded petrol min. 95 RONUse unleaded fuel with the octane rating 95 RON.
In case of necessity, you can refuel with petrol with the octane rating 91 RON if
petrol with the octane rating 95 RON is not available.
Even in the event of an emergency, petrol of a lower octane number than 91 RON
must not be used, otherwise the engine can be severely damaged!
Unleaded petrol with higher octane number
Unleaded petrol that has a higher octane number than that required by the en-
gine can be used without limitations.
On vehicles with prescribed unleaded petrol 95/91 RON, the use of petrol with a
higher octane number than 95 RON does not result in a noticeable power in-
crease or a lower fuel consumption.
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of petrol
with a higher octane number than 95 RON can increase the power and reduce
fuel consumption.
Prescribed fuel – unleaded petrol 98/(95) RON
Use unleaded fuel with the octane rating 98 RON. Unleaded petrol 95 RON can
also be used but results in a slight loss in performance.
In case of necessity, you can refuel with petrol with the octane rating 91 RON of
unleaded fuel with octane rating 98 RON or 95 RON is not available.
Even in the event of an emergency, petrol of a lower octane number than 91 RON
must not be used, otherwise the engine can be severely damaged!
Fuel additives
Only use unleaded petrol, which complies with the standard EN 228 (in Germany:
standard DIN 51626-1 or E10 for unleaded fuel with an octane rating of 95 RON and 91 RON or DIN 51626-2 or E5 for unleaded fuel with an octane rating of
95 RON and 98 RON), as these meet all of the requirements for fault-free engine operation. We therefore recommend that no fuel additives are used.
CAUTION
■ All ŠKODA vehicles with petrol engines must only be operated with unleaded
petrol. Just filling the tank with leaded petrol once will damage the exhaust sys-
tem!■
If, in an emergency, the vehicle has to be refuelled with petrol of a lower octane
number than the one prescribed, the journey must only be continued at medium
engine speeds and a low engine load. Driving at high engine revs or a high engine
load can severely damage the engine! Refuel using petrol of the prescribed oc-
tane number as soon as possible. 
168General Maintenance

■Engine parts can be damaged if petrol with a lower octane number than the one
prescribed is used.■
In no case may fuel additives with metal components be used, especially not
with manganese and iron content. Do not use any LRP fuels (lead replacement petrol) with metal parts - risk of serious damage to parts of the engine or exhaust
system!
■
Do not use any fuels with metal parts - risk of serious damage to parts of the
engine or exhaust system!
■
The use of unsuitable fuel additives can cause considerable damage to parts of
the engine or the exhaust system.

Diesel fuel
First read and observe the introductory information and safety warn-ings
on page 167.
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, GOST R 52368-2005/EN 590:2004 in Russia).
All diesel engines can be operated with diesel fuel with a maximum content of
7 % bio-fuel (B7), which complies with the standard DIN 52638 in Germany (in
Austria C 1590, in France EN 590).
Operation in winter – Winter-grade diesel fuel In the cold season, only use “winter-grade diesel fuel” which will still operateproperly even at a temperature of -20 °C.
It is often the case in countries with different climatic conditions that diesel fuels available have a different temperature characteristic. The ŠKODA Partners and
filling stations in the relevant country will be able to provide you with information
regarding the diesel fuels available.
Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures operation of
a vehicle using diesel fuel down to an environmental temperature of -25 °C.
Fuel additives
Fuel additives, so-called “flow improvers” (petrol and similar products) must not
be added to the diesel fuel.
CAUTION■ Just filling the tank once with diesel fuel that does not comply with the stand-
ard, can cause severe damage to parts of the engine, the fuel and exhaust sys-
tem!■
Damage caused by using diesel fuel which does not comply with the standards
are excluded from the warranty.
■
If a different fuel other than diesel fuel, which complies to the above mentioned
standards (e.g. petrol) is used by mistake do not start the engine or switch on the
ignition! Extensive damage to engine parts can occur! We recommend that the
fuel system is cleaned by a ŠKODA Partner.
■
Water which has collected in the fuel filter can cause engine faults.
■
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 cause considerable damage
to parts of the engine or fuel system.
■
Comply with the proscribed oil change intervals.

CAUTION
■
The amount of coolant additive in the coolant must never be allowed to be less
than 40 %.■
Over 60 % of coolant additive in the coolant reduces the antifreeze protection
and coolant effectiveness.
■
Other coolant additives that do not comply with the correct specifications can
above all significantly reduce the anticorrosion effect.
■
Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage!

level in the container directly.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a ŠKODA spe- cialist garage.
WARNING Do not continue your journey, if for some reason it is not possible to top up
the coolant under the prevailing conditions! Switch off the engine and seek
assistance from a ŠKODA specialist garage. 1)
On vehicles that are fitted with an auxiliary heater (auxiliary heating and ventilation), the coolant ca-
pacity is approx. 1 l larger.
