General Maintenance
Care and cleaning
General
Proper care retains the value of your vehicle.
Regular and proper care retains the value of your vehicle. It may also be
one of the requirements for the acceptance of warranty claims relating to
corrosion damage and paint defects on the bodywork.
You can obtain the necessary care products from Škoda dealers. Please
follow the instructions for use on the package.
WARNING
•Care products may be harmful to your health if not used
according to the instructions.
•Always store care products in a safe place, out of the reach of
children - risk of poisoning!
For the sake of the environment
•Always select environmentally-friendly products when purchasing
vehicle care products.
•Do not dispose of residues of care products in domestic waste.
Care of the exterior of vehicle
Washing the vehicle
Frequent washing protects your vehicle.
The best protection for your vehicle against harmful environmental influ-
ences is frequent washing and wax treatment. How often you should
wash your vehicle depends on a wide range of factors, such as:
•Frequency of use
•The parking situation (garage, below trees etc.)
•Season of the year
•Weather conditions
•Environmental influences
The longer insect residues, bird droppings, tree sap, road and industrial
dust, tar, soot particles, road salt and other aggressive deposits remain
adhering to the paintwork of your vehicle, the more detrimental their
destructive effect can be. High temperatures, such as those caused by
intensive sun's rays, accentuate this caustic effect.
It may therefore be necessary, in certain circumstances, to wash the car
once a week. It may also be sufficient, however, to wash the car once a
month followed by appropriate wax treatment.
It is essential to also thoroughly wash the underside of your vehicle at
the end of the winter road salting and gritting period.

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 !
WARNING
It is particularly important that you do not clean tyres with circular
spray jets. Damage may occur even at a relatively large spraying
distance and if sprayed only for a short time!
Caution
The water must be no hotter than 60°C, otherwise the vehicle can be
damaged.
Wax treatment
Good wax treatment is an effective way of protecting the paintwork from
harmful environmental influences and minor mechanical damage.
The vehicle must be treated with a high-quality hard wax polish at the
latest, when no more drops form on the clean paintwork.
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 197, “Wax treatment”.
We recommend using a preservative from Škoda genuine accessories
offered by your Škoda dealer.
Caution
•You must not treat mat painted parts or plastic with polishing products
or hard wax.
•Do not polish the paintwork of the vehicle in a dusty environment,
otherwise the paintwork can be scratched.

Care and cleaning199
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Caution
Never remove snow or ice from the windows with warm or hot water - risk
of formation of cracks in the glass!
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
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 the spray from Škoda original accessories
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 Škoda genuine accessories
offered by your Škoda dealer.

Care and cleaning201
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
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).
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.
We recommend using a cleaning product from Škoda genuine accesso-
ries offered by your Škoda dealer.
Caution
Solvent-free cleaners attack the material and can damage it.
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.
Leather should be treated from time to time according the
following guidelines depending on how much it is used.
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.

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.
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.

Fuel205
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 206, “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.

Fuel207
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
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.
For the sake of
the environment
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. You should not
continue refuelling - otherwise the expansion chamber in the fuel tank will
also be filled with fuel. Fuel might flow out of the tank when it heats up.
Emergency release of fuel filler flap
If the electric lock is faulty, you can also unlock the fuel filler flap
manually.
– Open the boot lid/luggage compartment door. – Unscrew the clip attaching the right-hand side trim panel and
pull the trim panel off the body.
– Pull on the loop in direction of arrow in order to unlock the fuel filler flap ⇒fig. 157 .
WARNING
When unlocking the fuel filler flap manually, pay attention to sharp
edges of the body - risk of injury!
