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 abrasion adhering to

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 partic ularly 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 la yer 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.
WARNING
One should remember when cleaning th e wheels that moisture, ice and road
salt may adversely affect braking ef ficiency - 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, ca n cause premature wear of the steering.
This means it is necessary to remove the dirt.
Underbody protection
The underside of your vehicl e 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 in tervals - this is best done at the begin-
ning and end of the winter - and to touch up any damaged areas.
Škoda Service Partners have suitable spray products available as well as the neces-
sary equipment and are familiar with the instructions for use. It is therefore best to
have such touch-up work or additional corrosion protection measures carried out
by a Škoda Service Partner.
WARNING
Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converte rs, diesel particle filter or heat
shields. When the engine reaches its operating temperature, these
substances might ignite - 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 protection regulations should observed when
using petroleum cleaner to re move wax - a risk of fire!

Taking care of your vehicle and cleaning the vehicle
202
Engine compartment
Good corrosion protection is very importan t, particularly in winter when one often
drives over its salt-strewn roads. One should therefore clean the whole engine
compartment before and after the salt spre ading period and treat with preservative
in order to prevent the salt from being destructive.
Škoda Service Partners 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 209, “Working in the engine
compartment”.
•Let the engine cool down before cleaning the engine compartment.
Caution
•Engine cleaning may be only be und ertaken when the ignition is off.
•It is recommended to cover the generator before washing the engine compart-
ment.
For the sake of the environment
The dirty water produced by washing the engine has washed away petrol, and resi-
dues of grease and oil and should therefor e be cleaned by an oil separator. This is
why engine washing should only be undertake n 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 le ather 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, head-
liner 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 accessories 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.

Fuel205
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Fuel
Petrol
Grades of petrol
There are various grades of petrol. Please read ⇒page 255, “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 206, fig. 184 .
A distinction is made between unleaded an d leaded petrol. All Škoda vehicles with
petrol engines are equipped with a catalyti c converter and must therefore be only
driven with unleaded petrol . Unleaded petrol complies with the standard
DINEN228 .
The individual grades of petr ol are distinguished by their octane number (RON).
Please adopt the following procedure if th e 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.
If, in an emergency, the only fuel availa ble 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, howeve r, be no advantages gained by this in
terms of engine performa nce 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 206, “Refuelling”.
Caution
•Filling the tank even only once with leaded petrol will result in the catalytic
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
Your vehicle can be operated with diesel fuel, which complies with the standard
DIN EN 590 .
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and similar
products) in diesel fuel.
If the quality of the diesel fuel is poor, it is then necessary to drain the fuel filter
more often than stated in the Service schedule.
You can find information on refuelling ⇒page 206, “Refuelling”.
Caution
•Use a fuel which complies with the standard DINEN590. Filling the tank even
only once, which does not comply with th e standard, can result in damage to the
fuel system.
•Water which has collected in the fuel fi lter can result in engine problems.
•Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must not
be refuelled and driven. Using this fuel (RME) can lead to damage to the engine or
the fuel system.

– Press the fuel tank flap closed.
The correct grade of fuel for your vehicle as well as the tyre size and inflation pres-
sures are stated on a sticker affixed to the inside of the fuel filler flap. Further infor-
mation on fuel ⇒page 205.
The fuel tank has a capacity of about 60 litres.
WARNING
Pay attention to any legal requirements if you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for
safety reasons. The canister can be da maged in the event of an accident and
fuel may leak out.
Caution
•Before refuelling it is necessary to switch off the auxiliary heating system (auxil-
iary heating and ventilation) *.
•Remove any fuel which has spilled onto the paintwork of your vehicle immedi-
ately - risk of paint damage!
•Vehicles fitted with catalytic converter sh ould 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.
•Make sure that the valve is not pressed into the filler tube when inserting the
pump nozzle into the filler tube. Otherwis e you are unintentionally filling up the
volume, which in case of heat can cause an expansion of the fuel. This can lead to
an overflow of fuel or damage to parts of the fuel reservoir.
•T h e f u e l t a n k i s f u l l j u s t a s s o o n a s t h e pump nozzle switches off for the first time,
provided the nozzle has been operated properly. Do not continue refuelling -
otherwise the expansion volume is filled up.
