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

WARNING■Work on your vehicle, which have been carried out unprofessionally, can
cause operational faults – risk of accident!■
We recommend you only use ŠKODA original accessories and ŠKODA original
parts on your vehicle. Only by doing so can you guarantee reliability, safety
and suitability.
■
ŠKODA cannot assume any liability for products which have not been ap-
proved by ŠKODA even though these may be products with a type approval or
have been approved by a nationally recognised testing laboratory.
Note
ŠKODA Original Accessories and ŠKODA Original Parts can be purchased from
ŠKODA Partners who will also professionally undertake the assembly of the pur-
chased parts.
Repairs and technical modifications
First read and observe the introductory information and safety warn-ings
on page 165.
Any damage caused by technical changes made without consent by ŠKODA is ex-
cluded from the warranty – see the warranty certificate.
Interference on the electronic components and their software can lead to opera-
tional faults. This interference can also impair not directly affected systems be- cause of the networking of the electronic components. In other words, the vehi-
cle's roadworthiness may be put at risk and increased wear on parts may arise.
Repairs and technical modifications must comply with ŠKODA guidelines.
WARNING■ Repairs and technical modifications which have been carried out unprofes-
sionally, can cause damage and can seriously impair the effectiveness of driv-
er assist system – risk of accident and serious injury!■
We recommend having these repairs and modifications replaced by a ŠKODA
specialist garage.
For the sake of the environmentTechnical documents regarding changes carried out on the vehicle must be kept
by the vehicle user, in order to be handed over to the recyclers later. This ensures
that vehicle recycling is in accordance with environmental regulations.
Changes and impairments of the airbag system
First read and observe the introductory information and safety warn-ings
on page 165.
We recommend that any modifications and repairs to the front bumper, doors, front seats, headliner or bodywork be carried out by a ŠKODA Partner. These vehi-
cle parts may include system components for the airbag system.
WARNING■ Airbag modules cannot be repaired, but must be replaced.■Repairs and modifications which have been carried out unprofessionally, can
cause damage, operational faults, and can also seriously impair the effective- ness of airbag system – risk of accident and fatal injury!■
Never install any airbag parts into the vehicle that have been removed from
old cars or have been recycled.
■
A modification to the suspension of the vehicle including the use of non-ap-
proved rim-tyre combinations can alter the functioning of the airbag and in-
crease the risk of serious or fatal injuries in an accident.
■
Parts of the airbag system may be damaged during installation/removal of
system parts and when performing other repair work. This may mean that the
airbags will not deploy properly or not at all in the event of an accident.

›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

WARNINGWhen working in the engine compartment, injuries, scolding, accident or fire
hazards may arise. For this reason, it is essential to comply with the warning
instructions stated below and with the general applicable rules of safety. The
engine compartment of your car is a hazardous area!■
Before beginning work in the engine compartment, please read the follow-
ing advice. ■ Turn off the engine and withdraw the ignition key.
■ Firmly apply the handbrake.
■ If the vehicle is fitted with a manual gearbox, move the gearshift lever into
Neutral, or if the vehicle is fitted with an automatic gearbox, move the se- lector lever into position P.
■ Allow the engine to cool.
■ Never open the bonnet if you can see steam or coolant flowing out of the
engine compartment – risk of scalding! Wait until the steam or coolant has stopped escaping.
■
While working in the engine compartment, please read the following advice.
■ Keep children clear of the engine compartment.
■ Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running!
■ Do not touch any hot engine parts – risk of burns!
■ The coolant additive and thus all of the coolant is harmful to your health.
■ Avoid contact with the coolant.
■ Coolant vapours are harmful to health.
■ Never open the end cover of the coolant expansion reservoir while the en-
gine is still warm. The cooling system is pressurized!
■ When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot coolant. ■ If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■ Always safely store the coolant additive in its original container out of the
reach of children – risk of poisoning!
■ If coolant is swallowed - consult a doctor immediately.
■ Do not leave any items such as cloths or tools in the engine compartment.
■ Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite!
WARNING (Continued)■ Whenever working in the engine compartment while the engine is running,
you must pay heed to the following warning instructions. ■Pay particular attention to moving engine parts (e.g. V-ribbed belt, alterna-
tor, radiator fan) and the high-voltage ignition unit - danger to life! ■ Never touch the electric wiring on the ignition system.
■ Avoid short circuits in the electrical system – particularly on the vehicle's
battery. ■ Always make sure that no jewellery, loose clothing or long hair can get
caught in rotating engine parts – hazard! Always remove any jewellery, tie back long hair and wear tight fitting clothing before completing any work.■
The following warning instructions must be observed if work has to be car-
ried out on the fuel or electrical system. ■ Always disconnect the vehicle battery from the electrical system.
■ Do not smoke.
■ Never work near open flames.
■ Always have a functioning fire extinguisher nearby.
■
Read the information and warning instructions on the fluid containers.
■
Keep fluids in their original containers and keep out of reach of children!
■
If you wish to work under the vehicle, you must secure the vehicle from roll-
ing away and support it with suitable supporting blocks: the car jack is not
sufficient for this – risk of injury!
■
The bonnet must always be properly closed when driving. This is why after
closing the bonnet, the lock must always be checked to ensure it has engaged
properly.
■
If you notice that the lock is not properly engaged while driving, stop the ve-
hicle immediately and close the bonnet – risk of an accident!
CAUTION
■ Always top up using the correct specification of fluids. This may result in major
operating problems and also vehicle damage!■
Never open the bonnet using the locking lever.
For the sake of the environment
In view of the environmentally friendly disposal of fluids, the specials tools and
knowledge required for such work, we recommend that fluids are changed by a
Škoda Partner as part of the inspection service. 170General Maintenance

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.
174General Maintenance

Brake fluid changeFirst read and observe the introductory information and safety warn-
ings
on page 169.
Brake fluid absorbs moisture. Over time it therefore absorbs moisture from the
environment.
Excessive water in the brake fluid may be the cause of corrosion in the brake sys-
tem.
The water content lowers the boiling point of the brake fluid.
The brake fluid must comply with the following standards or specifications: › VW 50114;
› FMVSS 116 DOT4.
WARNINGDo not use used brake fluid - the function of the brake system may be im-
paired - risk of accident!
CAUTION
Brake fluid damages the paintwork of the vehicle.
Note
The brake fluid is replaced as part of a proscribed Inspection service carried out by
a ŠKODA Partner.
Windscreen washer system
Fig. 152
Engine compartment: Wind-
screen washer fluid reservoirFirst read and observe the introductory information and safety warn-
ings on page 169.
The windscreen washer fluid reservoir is located in the engine compartment and
contains the cleaning fluid for the windscreen or rear window and for the head-
light cleaning system.
The capacity of the reservoir is about 3 litres or about 4.7 litres on vehicles that
have a headlight cleaning system.
Clear water is not sufficient to intensively clean the windscreen and headlights.
We recommend using clean washing water together with the screen cleaner from
the range of ŠKODA Original Accessories (in winter additionally with antifreeze)
which is capable of removing stubborn dirt.
In Winter, the washing water should always be mixed with antifreeze even if the
vehicle has heated windscreen washer nozzles.
Under exceptional circumstances, methylated spirits can also be used if no screen
cleaner with antifreeze is available. The concentration of methylated spirits must
not be more than 15 %. The freeze protection at this concentration is sufficient
only to -5 °C.
CAUTION
■ Under no circumstances must radiator antifreeze or other additives be added to
the windscreen washer fluid.■
If the vehicle is fitted with a headlight cleaning system, only cleaning products
which do not attack the polycarbonate coating of the headlights must be added
to the windscreen washer fluid.
■
Do not remove the filter from the windscreen washer fluid reservoir when re-
plenishing it with liquid otherwise the liquid transportation system can be conta-
minated, which can cause the windscreen washer system to malfunction.
