Automatic vehicle wash systems
The paintwork of the vehicle is sufficiently resistant that the vehicle can be
washed normally in automatic vehicle wash plants without any problem.
The actual stress to which the paintwork is subjected, however, depends
greatly on the design of the vehicle wash system, the filtering of the water
and the type of washing and care products used. If the paintwork of your
vehicle appears mat after being washed or even has scratches, point this
out to the operator of the vehicle wash plant. Use a different vehicle wash
plant, if necessary.
There are no particular points to note before washing your vehicle in such
a plant other than the usual precautionary measures (closing windows
and sliding/tilting roof, moving any factory-fitted aerials down flat against
the bodywork, etc.).
If you have any particular attached parts fitted to your car - such as spoiler,
roof rack system, two-way radio aerial - it is best to first of all consult the
operator of the car wash plant.
It is important to degrease the lips of the windscreen wiper rubbers after
passing through the automatic vehicle wash system.
Caution
Do not screw the swivelling down roof aerial tight before washing the
vehicle in an automatic vehicle wash system - risk of damage!
Washing vehicle by hand
It is important to first soften the dirt with plenty of water and rinse it off as
thoroughly as possible before washing your vehicle by hand.
One should then clean the vehicle using a soft washing sponge,
washing glove or a washing brush and only slight pressure. Work from
the top to the bottom - beginning with the roof. Only place slight pressure
on the vehicle paintwork during cleaning Only use a shampoo for stub-
born dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for
such areas.
Rinse off the vehicle well after giving it a wash and dry it off using a
chamois leather.
Caution
•Do not wash your vehicle in bright sunlight - risk of paint damage.
•Ensure that the jet of water is not aimed directly at the locks or at the
door and panel joints if you spray your vehicle in winter down with a hose
- risk of freezing.
•Do not use any insect sponges, rough kitchen sponges or similar
cleaning products - risk of damage to the surface of paintwork.
WARNING
When washing your vehicle in the winter: Water and ice in the
brake system can affect the braking efficiency - risk of accident.
WARNING
•The ignition should always be switched off when you wash your
vehicle - risk of accident!
•Protect your hands and arms from sharp-edged metal parts
when you are cleaning the underfloor, the inside of the wheel hous-
ings or the wheel trims - risk of cuts.

For the sake of the environment
Only wash your vehicle at washing bays specifically reserved for this
purpose. This ensures that no water which may be contaminated by oil
flows into the sewage system. It is not even permitted to wash your vehicle
in certain areas except at such specific washing bays.
Washing with a high-pressure cleaner
When you wash your vehicle with a high-pressure cleaner, it is essential
to comply with the instructions for use of the cleaning equipment. This
applies in particular to the pressure used and to the spraying distance .
Maintain a sufficiently large distance to soft materials such as rubber
hoses or insulation material.
On no account use circular spray nozzles or so-called dirt cutters .
The water containing wax must be no hotter than 60°C.
Caution
It is particularly important that you do not clean tyres with circular spray
jets. Damage to tyres may occur even at a relatively large spraying
distance and if sprayed only for a short time.
Wax treatment
Good wax treatment is an effective way of protecting the paintwork from
harmful environmental influences and minor mechanical damage.
A new layer of a high-quality hard wax polish can be applied to the clean
bodywork after it has dried thoroughly. Even if you use a wax preserver regularly we still recommend that you treat the paintwork of the vehicle at
least twice a year with hard wax.
Caution
Never apply wax to the windows.
Polishing
Polishing is only necessary if the paintwork of your vehicle has become
unattractive and if it is no longer possible to achieve a gloss with wax
preservers.
You must treat the paintwork with a wax preserver if the polish you use
does not contain any preserving elements
⇒page 191, “Wax treatment”.
We recommend using a preservative from the range of accessories
offered by your Skoda dealer.
Caution
You must not treat mat painted parts or plastic with polishing products or
hard wax.
Trim strips
Use pH neutral care products to remove stains and coatings on trim
strips - in other words not chrome care products. Škoda Dealers have
available a range of environmentally compatible cleaning products which
have been tested and approved for your car.

Care and cleaning
192
Paint damage
Slight damage to paintwork such as scratches, scuffs or traces of chip
damage must be touched up immediately with paint (Skoda painting pen)
before any corrosion can result. You can of course have this work carried
out by a Škoda dealer.
Škoda dealers have a range of matching touch-up pens or spray cans
available for your vehicle.
The paint number of the original paintwork of your vehicle is indicated on
the vehicle data sticker ⇒page 249.
Any corrosion which has already have formed must be removed thor-
oughly. Apply a corrosion protection primer and then the paint to the
affected point. You can of course have this work carried out by a Škoda
dealer.
Plastic parts
External plastic parts are cleaned by normal washing. Plastic parts and
synthetic leather can also be treated with special solvent-free plastic
cleaning agents if a damp cloth is not sufficient. Paint care products are
not suitable for plastic parts.
Windows
Only use a plastic ice scraper for removing snow and ice from the
windows and mirrors. You should not move the ice scraper forward and
backward but in one direction on the window which you are cleaning in
order to avoid any damage to the surface of the glass. You can best remove residues of rubber, oil, grease, wax or silicone by
using a special window cleaner or a special silicone remover.
You should also clean the windows regularly from the inside.
Do not use window leathers which you have used to polish the vehicle
body to dry off the windows. Residues of preservatives in the window
leather can dirty the window and reduce visibility.
Do not affix any stickers over the inside of the rear window to avoid
damage to the
heating elements of the rear window heater .
We recommend using a preservative from the range of accessories
offered by your Skoda dealer.
The headlight lenses
Please do not use any aggressive cleaning or chemical solvent products
- risk of damage to the plastic lenses Please use soap and clean warm
water.
Caution
Never wipe the headlights dry and do not use any sharp objects for
cleaning the plastic lenses, this may result in damage to the protective
paintwork and consequently in formation of cracks on the headlight
lenses, e.g through effect of chemical products.
Door and window seals
The rubber seals on the doors, boot lid, bonnet, sliding roof and windows
remain supple and last longer if you treat them from time to time with a
rubber care product (e.g. silicone spray). You also avoid premature wear

Care and cleaning193
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
of the seals and prevent leakages in this way. It is also easier to open the
doors. Rubber seals which are well cared for also do not stick together in
cold winter weather.
Locks
We recommend that you use Genuine Škoda Spray with regreasing and
anticorrosive effect for de-icing locks.
Note
When washing your vehicle, ensure that as little water as possible gets
into the locks.
Wheels
Steel wheels
You should also thoroughly wash the wheels and wheel trims when giving
your vehicle its regular wash. This prevents any brake dust, dirt and road
salt from sticking to the wheel hubs. You can remove stubborn brake abra-
sion adhering to the wheels with an industrial cleaner. Touch up any
damage to the paintwork on the wheels before rust is able to form.
Light alloy wheels
Regular care of light alloy wheels is necessary in order to retain their
decorative appearance over long periods. It is particularly important to
remove any road salt and brake abrasion from light alloy wheels every two
weeks, otherwise the surface will suffer. Wash thoroughly and then treat
the wheels with a protective product for light alloy wheels which does not
contain any acidic components. You should provide the wheel hubs with
a hard wax layer every three months. You must not use any products
which cause abrasion when treating the wheel hubs. Any damage to the
paint layer on the wheel hubs must be touched up immediately.
We recommend using a preservative from the range of accessories
offered by your Skoda dealer.
Note
Severe layers of dirt on the wheels can also result in wheel imbalance.
This may show itself in the form of wheel vibration which is transmitted to
the steering wheel which, in certain circumstances, can cause premature
wear of the steering. It is therefore important to clean dirty wheels.
Underbody protection
The 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.
Škoda dealers have suitable spray products available as well as the
necessary equipment and are familiar with the instructions for its use. It is
therefore best to have such touch-up work or additional corrosion protec-
tion measures carried out by a Škoda dealer.
WARNING
One should remember when cleaning the wheels that moisture, ice
and road salt may adversely affect braking efficiency - risk of an
accident!

Care and cleaning
194
Protection of hollow spaces
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.
This wax protection does not require to be inspected or re-treated. If a
small amount of wax flows out of the cavities at high temperatures, please
remove it with a plastic scraper and cleaning petroleum.
Care of the interior of vehicle
Plastic parts, artificial leather and cloths
You 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. Upholstery cloth and cloth trim on the doors, luggage compartment cover,
headliner etc. are best treated with special cleaning products, using if
necessary a
dry foam and a soft sponge or brush.
Fabric covers of electrically heated seats
Do not clean the seat covers moist as this may result in damage to the
seat heating system.
Clean such covers using special agents, for example dry foam.
Natural leather
Natural leather requires quite particular care and attention.
General
The intensity of the dyeing determines the visual appearance and the
properties. If the typical signature of nature is detectable on the surface of
the leather, then this is a natural nappa leather which offers excellent
seating comfort and well being. Fine veins, closed scabs, insect bites,
natural creases as well as a fogginess with graduations in shade, remain
visible and represent characteristics of the genuineness of the natural
material.
Natural nappa leather does not have a covering dye layer. It is therefore
more sensitive. Remember that leather is subject to particularly severe
wear-and-tear from children, animals or other influences.
In contrast, leathers with a more or less covering dye layer are harder
wearing. This has a positive effect on the wear properties of the leather in
daily use. In this case, however, the typical natural characteristics are
scarcely or no longer visible, which does not have any effect on the quality
of the leather itself, however.
WARNING
Never use additional underbody protection or corrosion-protec-
tion agents for the exhaust pipes, catalytic converters or heat
shields. Such substances might ignite when driving - risk of fire!
WARNING
Safety and environmental protection regulations should observed
when using petroleum cleaner to remove wax - a risk of fire!

Leather cleaning and care
In view of the exclusiveness of the qualities and characteristics of the
leathers used (such as sensitivity to oils, greases, dirt etc.) a certain care-
fulness in use and particular care are required. Dark items of clothing, for
example, (particularly if these are moist and have poor quality dyeing)
may colour the leather seats. Dust and dirt particles in pores, creases and
seams may chafe and damage the surface. For this reason, care for the
leather regularly, or according to the wear-and-tear. After a lengthy period
of use, your leather seats will acquire a typical and unique patina. This is
characteristic of the natural product leather and is a sign of genuine
quality.
Please pay attention to the following notes in order to retain the value of
the natural material over its full life:
Caution
•Avoid leaving your vehicle for lengthy periods in bright sunlight in order
to avoid bleaching the leather. If you leave your vehicle parked in the open
for lengthy periods, protect the leather from the direct rays of the sun by
covering it over.
•Sharp-edged objects on items of clothing such as zip fasteners, rivets,
sharp-edged belts may leave permanent scratches or signs of rubbing on
the surface.
Note
•Use a care cream with light blocker and impregnation effect regularly
and each time after cleaning the leather. The cream nourishes the leather,
allows it to breathe and keeps it supple and also provides moisture. It also
creates surface protection.
•Clean the leather every 2 to 3 months, remove fresh soiling each time
this occurs.
•Remove fresh stains such as those from ball-point pens, ink, lipstick,
shoe cream etc., as quickly as possible.
•Care also for the leather dye. Refreshen areas which have lost their
colour with a special coloured leather cream as required.
Cleaning and care of leather upholstery
Normal cleaning
– Clean soiled areas of the leather with slightly moistened
cotton or woollen cloth.
Severe soiling
– Clean severely soiled areas with a cloth dipped in a mild soapy solution (2 spoonfuls of natural soap to 1 litre of water).
– 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 stains which are water-based (e.g. coffee, tea,
juices, blood etc.) with an absorbent cloth or household paper
or use the cleaner from the care set for a stain which has
already dried in.
– Remove fresh stains which are oil based (e.g. butter, mayon-
naise, chocolate etc.) with an absorbent cloth or household
cleaning paper or with the cleaner from the care set if the stain
has not yet penetrated into the surface.
– Use a grease dissolver for grease stains which have dried
in .

Care and cleaning
196
–Eliminate special stains (e.g. ball-point pens, felt pen, nail
varnish, dispersion paint, shoe cream etc.) with a special stain
remover suitable for leather.
Leather care
– Treat the leather every six months with the leather care product available from Škoda dealers.
– Apply only a small amount of the care product.
– Dry the leather off with a soft cloth
It is best to consult your Škoda dealer if you have any questions regarding
cleaning and care of the leather interior.
Caution
You must on no account treat the leather with solvents (e.g. gasoline,
turpentine), floor wax, shoe cream or such like.
Alcantara upholstery
Do not use any leather care products for cleaning Alcantara upholsteries.
Eliminating dust and dirt
Wipe the Alcantara upholstery with a slightly moistened, soft cloth or clean
the covers with a suitable shampoo.
Removing stains
Moisten a soft cloth with lukewarm water or diluted methylated spirits and
dab the stain from the edges toward the middle.
Seat belts
– Keep the seat belts clean.
– Wash seat belts which have become soiled using a mild soapy solution.
– Inspect the seat belts regularly to ensure they are in good condition.
Belt webbing which has become severely soiled may prevent the inertia
reel from reeling up the belt properly.
Engine compartment
Good corrosion protection is very important, particularly in winter when
one often drives over its salt-strewn roads. One should therefore clean the
whole engine compartment and the radiator tank before and after the salt
spreading period and treat with preservative in order to prevent the salt
from being destructive.
WARNING
•The seat belts must not be removed for cleaning.
•Never clean the seat belts chemically as dry cleaning may
destroy the fabric. The seat belts must also not be allowed to come
into contact with corrosive liquids (such as acids etc.).
•Seat belts which have damage to the webbing, the connections,
the inertia reel or the lock should be replaced by a Škoda dealer.
•Inertia reel belts must be completely dried before being reeled
up.

Care and cleaning197
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Skoda dealers have the cleaning agents and preservatives recommended
by the manufacturer and also the required equipment.
Caution
•Engine cleaning may be only be undertaken when the ignition is off.
•It is recommended to cover the generator before washing the engine
compartment.
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
garage or at a fueling station (when these are fitted with the required
equipment).
WARNING
It is necessary to observe the guidelines given in the chapter
before working on the engine compartment ⇒page 203.

Fuel
198
Fuel
Petrol
Grades of petrol
There are various grades of petrol. Please read the brochure “Technical
Data” in order to know which grade of petrol your vehicle requires. You will
also find the same information affixed to the inside of the fuel filler flap of
your vehicle ⇒page 200, fig. 151 .
A distinction is made between unleaded and leaded petrol. All Škoda vehi-
cles with petrol engines are equipped with a catalytic converter and must
therefore be only driven with unleaded petrol. Unleaded petrol complies
with the standard EN 228 .
The individual grades of petrol are distinguished by their octane number
(RON). Please adopt the following procedure if the grade of petrol which
you normally use is not be available in exceptional circumstances:
•Engines which need unleaded premium petrol 95 RON can also be
run on unleaded regular petrol 91 RON. This does, however, result in a
slight loss in performance.
•Engines which need unleaded premium petrol 98 RON can also be
run on unleaded regular petrol 95 RON. This does, however, result in a
slight loss in performance. You can in exceptional circumstances also
use unleaded regular petrol of 91 RON in the event that no unleaded
premium petrol of 98 RON or 95 RON is available. Refuel as soon as
possible with unleaded premium plus of 98 RON or unleaded premium
petrol of 95 RON.
If, in an emergency, the only fuel available is one which has a lower octane
number than that required by the engine then only drive at medium engine
speeds and lower engine loadings. You can make unlimited use of fuel which has a higher octane number
than that required by the engine. There will, however, be no advantages
gained by this in terms of engine performance and fuel consumption!
The handling, performance and life of your engine are determined to a
significant extent by the quality of the fuel. Do not use any petrol additives.
Use a fuel complying with the standard.
You can find further information on refuelling
⇒page 200.
Caution
•Filling the tank even only once with leaded petrol will result in the cata-
lytic converter being destroyed.
•Operating the engine with petrol of a low octane number can result in
engine damage at high revolutions or severe engine loading.
Diesel
Grade of diesel fuel
Grades of diesel fuel
Your vehicle can be driven with the following grades of diesel fuel:
•Diesel fuel with a cetane number of at least CN 49 (the cetane number
CN is a measure of the ignition performance of the diesel fuel). Diesel fuel
must comply with the standard EN 590 .
•Biofuel (RME rape oil methyl ester fuel) must comply with the
standard EN 51 606 . Please refer to the following guidelines
⇒ page 199.

Fuel199
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and
similar products) in diesel fuel.
It is then necessary to have the
fuel filter drained of water by a Škoda
dealer more often than stated in the service schedule if the quality of the
diesel fuel used is poor.
You can find information on refuelling ⇒page 200, “Refuelling”.
Caution
•Use a fuel complying with the standard. Filling the tank even only once,
which does not comply with the standard, can result in damage to the fuel
system.
•Water which has collected in the fuel filter can result in engine
problems.
Biofuel
Biofuel (methyl ester from rape oil) is manufactured from vegetable oil by
means of a chemical process.
Biofuel does not contain sulphur. This means that no sulphur dioxide
(SO
2) is produced when it is burnt.
The exhaust gases contain less
•carbon monoxide (CO)
•hydrocarbons (HC)
•particles (soot)
than when operating with conventional diesel fuel.
The Biofuel is more biodegradable. When using biofuel pay attention to the following points:
•The
Performance may be reduced slightly if you switch to driving with
biofuel.
•The Fuel consumption may increase slightly if you switch to driving
with biofuel.
Biodiesel conforming to the standard E 51 606 can be mixed in any
desired ratio with diesel fuel conforming to the standard EN 590.
We recommend refuelling with diesel fuel at temperatures below -10°C.
Caution
Filling the tank even only once with biofuel, which does not comply with
the standard standard E 51 606 , can result in damage to the fuel
system.
Operation in winter
Winter-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 becomes
viscous as a result of paraffin separation.
It is therefore the case that DIN EN 590 prescribes diesel fuel class for
certain periods of the year which can also be purchased at the corre-
sponding 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 countries with different climatic conditions that diesel
fuels available have a different temperature characteristic. Škoda dealers
and filling stations in the country concerned will be able to provide you with
information regarding the diesel fuels available.
