Taking care of your vehicle and cleaning the vehicle
238
WARNING
One should remember when cleaning the wheels that moisture, ice
and road salt may adversely affect braking efficiency - risk of an
accident!
Note
Severe layers of dirt on the wheels can also result in wheel imbalance.
This may show itself in the form of a wheel vibration which is transmitted
to the steering wheel which, in certain circumstances, can cause prema-
ture wear of the steering. This means it is necessary to remove the dirt.
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
Never use additional underbody protection or corrosion-protection
agents for the exhaust pipes, catalytic converters or heat shields.
Such substances might ignite when driving - risk of fire!
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. 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 prot ection regulations should be
observed when using petroleum cleaner to remove wax - a risk of
fire!
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
engine compartment before and after the salt spreading period and treat
with preservative in order to prevent the salt from being destructive.
Škoda dealers have the cleaning agents and preservatives recommended
by the manufacturer and also the required equipment.
WARNING
•It is necessary to observe the guidelines given in the chapter
before working on the engine compartment ⇒page 248.
•Let the engine cool down before cleaning the engine compart-
ment.

Caution
•Engine cleaning may 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
specialist 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 wet 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 pH-neutral 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.

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 245, fig. 188 .
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 petrol 91 RON. This does, however, result in a slight loss
in performance.
•Engines which need unleaded premium plus 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 circum-
stances also use unleaded petrol of 91 RON in the event that no
unleaded premium plus petrol of 98 RON or premium plus petrol of 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 245, “Refuelling”.
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
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 DIN EN 590.
„Biofuel (RME rape oil methyl ester fuel) must comply with the DIN
EN 14 214 . Please refer to the following guidelines ⇒page 243.

„Diesel fuel mixture according to standard CSN 65 6508 from
02/2003 contains diesel fuel according to standard DIN EN 590 and a
concentration of biofuel (rape oil methyl ester) according to standard
DINEN14214 in the following two concentrations:
„5% share of biofuel RME according to the standard DINEN14214
- Denomination SMN 5,
„30% share of biofuel RME according to the standard
DINEN14214 - Denomination SMN 30.
The same principles apply for the diesel fuel mixture as for the biofuel
⇒ page 243.
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 245, “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*
The possibility to refuel with biofuel only applies to vehi-
cles, which have been adapted at the factory for its use.
Biofuel (RME rape oil methyl ester fuel) must comply with the DIN EN
14 214 ⇒ .
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.
We recommend refuelling with diesel fuel at temperatures below -10°C.
Biofuel conforming to DIN EN 14 214 can be mixed in any desired ratio
with diesel fuel conforming to the standard DIN EN 590.

Caution
•Filling the tank even only once with biofuel, which does not comply with
the standard DIN EN 14 214 , can result in damage to the fuel system.
•The possibility to refuel with biofuel only applies to vehicles, which
have been adapted at the factory for its use. Filling the tank even only
once with biofuel, which does comply with the standard DIN EN 14 214,
can otherwise result in damage to the fuel system.
•Water which has collected in the fuel filter can result in engine prob-
lems.
•It is prohibited to use biofuel and diesel fuel mixture (RME) for diesel
vehicles which are fitted with diesel particle filter.
Note
•On the inside of the fuel filler flap you will find the information whether
your vehicle can be driven with biofuel.
•When using biofuel certain maintenance work must be carried out
earlier than when using diesel fuel according to DINEN590 - see Service
schedule.
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.
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 temper-
ature 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.

246
Caution
•Remove any fuel which has spilled onto the paintwork of your vehicle
immediately - risk of paint damage!
•Vehicles fitted with catalytic converter should never be allowed to let
the fuel tank to 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.
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.

Engine oil
Engine oil specifications
The grade of engine oil should be selected in accordance
with precise specifications.
The engine of your vehicle has been factory-filled with a high-grade oil
which you can use throughout the year - except in extreme climatic
regions.
You can mix various oils together with each other when refilling with oil.
This does not, however, apply for models with flexible service intervals
(QG1).
Engine oils are, of course, undergoing continuous further development.
Thus the information stated in this Owner's Manual is only correct at the
time of publication.
Škoda dealers are informed by Škoda Auto about current changes. This
why you should always have engine oil changed by your Škoda dealer.
The specifications (VW standards) stated in the following must be indi-
cated separately or together with other specifications on the bottle.
