Keeping a log of your fuel consumption
If you really wish to ke ep a close check on your fuel consumption, it is best to enter
the figures in a logbook. This does not take much time but is a very worthwhile exer-
cise. It enables you to detect any change (positive and negative) at an early stage
and to take any appropriate action.
If you find that your fuel consumption is too high, you sh ould reflect on how, where
and in what conditions you have driven the vehicle since you last refuelled.
Environmental compatibility
Environmental protection has played a majo r role in the design, selection of mate-
rials and manufacture of your new Škoda. Particular emphasis has been paid to a
number of aspects, including:
Design measures
•joints designed to be easily detached,
•simplified disassembly due to the modular structure system,
•improved purity of different classes of materials,
•identification of all plastic parts in accordance with VDA Recommendation 260,
•reduced fuel consumption and exhaust emission CO2,
•minimum fuel leakage during accidents,
•reduced noise.
Choice of materials
•extensive use of recyclable material,
•air conditioning filled wi th CFC-free refrigerant,
•no cadmium,
•no asbestos,
•reduction in the “vaporisation” of plastics.
Manufacture
•solvent-free cavity protection,
•solvent-free protection of the vehicle for transportation from the production
plant to the customer,
•the use of solvent-free adhesives,
•no CFCs used in the production process,
•without use of mercury,
•use of water-soluble paints.
Motoring abroad
General
Other circumstances may exist abroad.
It is also possible, in ce rtain countries, that the Škod a Service Partner network is
limited or has not been established yet. This is the reason why obtaining certain
spare parts may be somewhat complicate d and specialist garage personnel may
only be able to ma ke li mite d re pa irs. Škoda Auto a.s. i n the Czech Republic and rele -
vant importers are happy to provide info rmation about technical aspects of the
vehicle, required maintenance work and possibilities for getting repairs done.
Unleaded petrol
A vehicle fitted with a petrol engine must always be refuelled with unleaded petrol
⇒ page 188. The automobile associations can provide you with information
regarding the locations of filling stations which offer unleaded petrol.
Headlight
The low beam of your headlights is set asym metrically. It illuminates the side of the
road on which you are driving to a greater extent. If you drive abroad on the other
side of the road, you wi ll dazzle oncoming traffic.
In order to prevent the dazzling of oncoming traffic, it is necessary that an adjust-
ment of the headlights is carried out by your Škoda Service Partner.

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.

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.

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 be comes 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 pu rchased at the corresponding 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 diff erent climatic conditions that diesel fuels
available have a different temperature characteristic. Škoda Service Partners and
filling stations in the country concerned wi ll be able to provide you with informa-
tion 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 temperature 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.
Refuelling
The filler flap is automatically unlocked or locked with the central locking.
Opening the fuel filler cap
– Press onto the left side of the fuel filler flap ⇒fig. 183 .
– Unscrew the fuel filler cap anti-clo ckwise and place the fuel filler cap
from above on the fuel filler flap ⇒fig. 184 .
Closing fuel filler cap
– Screw on the cap by turning it to the right until it is heard to lock.

– 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.

WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi ng! Wait long enough until the steam
or coolant has stopped escaping.
•For safety reasons, the bonnet must always be properly closed when
driving. One should therefore check that the lock has in fact engaged prop-
erly after closing the bonnet.
•Stop your vehicle immediately while driv ing if you notice that the lock is
not properly engaged and close the bonne t properly - risk of an accident!
Caution
Ensure that the arms of the windscreen wipers are correctly in place against the
windscreen before opening the bonnet otherwise damage could occur to the
paintwork.
Working in the engine compartment
Particular care is required when carrying out any work in the engine
compartment!
There is a risk of injuries, scalding, accidents and fire when working in the
engine compartment, e.g. inspecting and replenishing oil and other fluids. For
this reason, it is essential to comply with the warning instructions stated
below and with the general applicable rules of safety. The engine compart-
ment of your car is a hazardous area ⇒ .
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi ng! Wait long enough until the steam
or coolant has stopped escaping.
•Switch off the engine and pull out the ignition key.
•Apply the handbrake firmly.
•If your vehicle is fitted with a ma nual gearbox, move the gearshift lever
into Neutral, or if it is fitted with automatic gearbox, move the selector lever
into position P.
•Allow the engine to cool down.
•Keep children clear of the engine compartment.
•Never spill oil and other fluids over the hot engine. Such fluids (e.g. the
antifreeze contained in the coolant) may ignite!
•Avoid short circuits in the electrical system - particularly on the battery.
•Never place your hand into the radiator fan as long as the engine is still
warm. The fan might suddenly start running!
•Never open the cap of the coolant expa nsion bottle as long as the engine
is still warm. The cooling system is pressurized!
•Cover over the cap of the coolant expansion reservoir with a large cloth
when opening it as protection for your face, hands and arms from hot steam
or hot coolant.
•Do not let objects, such as e.g cleaning cloth or tools lie in the engine
compartment.
•If you wish to work under the vehicle, you must secure the vehicle from
rolling away and support it with suitable supporting blocks: the car jack is
not sufficient for this - risk of injury!
•In cases where it be necessary to carry out inspection work when the
engine is running there is an additional risk from rotating parts (e.g. the V-
ribbed belt, alternator, radiator fan) and from the high-voltage ignition
system. Please observe in addition the following.
−Never touch the electrical cabl es of the ignition system.
− Absolutely avoid any jewellery, loose items of clothing or long hair
from getting into the rotating parts of the engine - Hazard! Therefore
remove any jewellery beforehand, tie up your hair and wear tight fitting
clothing.

Oil level within range
–You must not top up the oil.
Oil level within range
–You may top up the oil. It is possible that the oil level may then be
within range after doing this.
Oil level within range
–You must top up the oil ⇒page 212. It is sufficient, once this is done,
to keep the oil level is within range .
It is normal for the engine to consume oil. The oil cons umption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. The oil consumpt ion may be slightly higher than this
during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range if the engine has been
operating at high loads, for example during a lengthy motorway trip during the
summer months, towing a trailer or negotiating a high mountain pass, but not
above this .
The warning light in the instrument cluster* will indicate ⇒page 35, “Engine oil
level* ” whether the oil level is too low. In this case, check the oil level as soon as
possible. Top up with an a ppropriate quantity of oil.
Caution
•The oil level must on no account ex tend beyond the range . Danger of
damaging the catalytic converter.
•Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Switch of the engine and contact and
obtain professional assistance from a specialist garage.
Replenishing engine oil
– Inspecting the engine oil level ⇒page 211.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 210.
– Inspect the oil level ⇒page 211, “Check engine oil level”.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING
•Avoid dripping oil onto hot parts of the engine when topping up will oil -
a risk of fire!
•Read and observe the warning notes ⇒page 209, “Working in the engine
compartment” before working in the engine compartment.
For the sake of the environment
The oil level must on no account be above the range ⇒page 211. Oil will other-
wise be drawn in through the crankcase ventilation and may pass through the
exhaust system to atmosphere. The oil ma y combust in the catalytic converter and
damage it.
Changing engine oil
The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator ⇒page 12, “Service Interval Display”.
WARNING
•Only carry out the engine oil change, if you have the required profes-
sional knowledge!

Wheels and Tyres
Wheels
General information
•New tyres do not offer optimal grip at first and should therefore be run in for
about 500 km at a moderate speed and an appropriately cautious style of driving.
You will also profit from longer tyre life.
•The tread depth of new tyres may differ because of design features and the
configuration of the tread (d epending on the type of tyre and the manufacturer).
•Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angles in order to avoid damage to tyres and wheel trims.
•Inspect your tyres from time to time for damage (punctures, cuts, splits and
bulges). Remove foreign bodi es from the tyre profile.
•Damage to tyres and wheels is frequent ly not visible. Unusual vibrations or
pulling of the vehicle to one side could be a sign of tyre damage. Please reduce
your speed immediately and stop if you suspect that a wheel is damaged.
Inspect the tyres for signs of damage (bulges, splits, etc.) If no visible damage is
present, please drive at an appropriately slow speed and carefully to the nearest
specialist garage in order to have your vehicle inspected.
•Also protect your tyres from contact with oil, grease and fuel.
•Immediately replace any dust caps of the valves which have got lost.
•Mark wheels before removing them so th at their previous direction of running
can be maintained when mounted them again.
•Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not fixed to a wheel trim should be stored
upright.
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of the tyre. This
indicates the direction of rotation of the tyre, and it is essential that the tyres are
fitted on to run in this direction. Only then are the tyres able to provide the optimal
properties in terms of grip, low no ise, wear-and-tear and aquaplaning. Further information concerning the use of unidirectional tyres
⇒page 226.
WARNING
•New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!
•Never drive with damaged tyres - risk of accident!
Note
Please observe the various differing legal requirements regarding tyres.
Tyre life
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened co nsiderably if the tyres are insufficiently
or over-inflated and this will have an advers e effect on the handling of your vehicle.
Correctly inflated tyres are of partic ular importance when travelling at high speeds .
It is therefore good to check the pressure at least once a month and also before
