Power steering
Power steering assists the driver in steering the vehicle and reduces the
physical force needed for steering.
It is still possible to fully steer the vehicle if the power steering fails or if the
engine is not running (vehicle being towed in). The only difference is that
greater physical effort is required.
If the steering is turned to full lock when the car is stationary, you will
place great stresses on the power steering system. Turning the steering
to full lock in such a situation will be accompanied by noises. In addition,
the idling speed of the engine will drop briefly.
Caution
Do not leave the steering at full lock for more than 15 seconds when the
engine is running - risk of damaging the power steering!
Note
•Have the steering inspected as soon as possible by a Škoda dealer if
there is a leak or fault in the system.
•The power steering requires a special hydraulic oil. The oil reservoir is
located at the front left of the engine compartment ⇒page 210. The
correct hydraulic oil level is important for proper operation of the power
steering system.

New brake pads
Allow for the fact that new brake pads do not achieve their full braking effi-
ciency until approximately 200 kilometres. New brake pads must be first
“run in” before they develop their optimal friction force. You can, however,
compensate for this slightly reduced braking force by increasing the pres-
sure on the brake pedal.
This guideline also applies to any new brake pads installed at a future
date.
During the running-in period, you should avoid excessive stresses on the
brakes. This includes, for example, violent braking, particularly from very
high speeds, and also when crossing mountain passes.
Catalytic converter
Proper operation of the emission control system (catalytic
converter) is of major significance for driving your vehicle
in an environmentally conscious way.
Please refer to the following guidelines:
– For vehicles with petrol engine only refuel with unleaded petrol
⇒page 204, “Grades of petrol”.
– Never run the fuel tank completely empty.
– Do not switch off the ignition while you are driving the vehicle.
– Do not pour too much oil into the engine ⇒page 213,
“Replenishing engine oil”. – Do not tow-start the vehicle over a distance of more than 50
metres ⇒page 248, “Tow-starting a vehicle”.
If you drive your vehicle in a country in which unleaded petrol is not avail-
able, you must have the catalytic converter replaced later when driving the
vehicle into a country in which use of a catalytic converter is mandatory.
WARNING
•In view of the high temperatures which may be produced in the
catalytic converter, one should always park a vehicle in such a way
that the catalytic converter cannot come into contact with easily
flammable materials below the vehicle - a risk of fire!
•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!
Caution
•Vehicles fitted with catalytic converter should never be allowed to let
the fuel tank to run completely empty. An irregular fuel supply can result
in poor ignition or misfiring. Unburnt fuel may get into the exhaust system
and damage the catalytic converter.
•Filling the tank even only once with leaded petrol will result in the cata-
lytic converter being destroyed.
•If you detect misfiring, a drop in performance or irregular engine
running when driving, reduce your speed immediately and have the
vehicle inspected by the nearest Škoda dealer. The symptoms described
may be caused by a fault in the ignition system. Unburnt fuel may get into
the exhaust system and damage the catalytic converter.

Driving and the Environment
184
For the sake of the environment
Even if the exhaust system is operating properly, a sulphur-like exhaust
odour may be produced under certain operating conditions of the engine.
This depends on the sulphur content of the fuel. It is often sufficient to
refuel with unleaded premium-grade petrol of a different brand or at a
different filling station.
Motoring abroad
General
Other circumstances may exist abroad.
It is also possible, in certain countries, that the Škoda dealership network
has not been established yet. This is the reason why obtaining certain
spare parts may be somewhat complicated and specialist garage
personnel may only be able to make limited repairs. Škoda Auto in the
Czech Republic and relevant importers are happy to provide information
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 183. The automobile associations can provide
you with information regarding the locations of filling stations which offer
unleaded petrol.
Headlights
The low beam of your headlights is set asymmetrically. 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 will dazzle oncoming traffic.
It is necessary in order to avoid dazzling oncoming traffic to stick a sticker
over a certain part of the headlights.
Windscreen wiper stickers are available at Škoda dealers.
Headlights with Xenon lamps are designed for driving in countries with
traffic on the right or on the left. Have this done always at a Škoda dealer.
Note
You can obtain further information regarding masking over or converting
the headlights from your Škoda dealer.
Avoiding damage to your vehicle
When driving on poor roads and lanes or when driving over kerbstones,
steep ramps etc., you must pay particular attention to ensuring that any
low-slung parts of the vehicle, such as spoiler and exhaust, do not touch
the ground and get damaged.
This particularly applies to models with a lowered suspension (sport
suspension) and also when your vehicle is fully laden.

Driving and the Environment187

Reducing idling
Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at
a level crossing or at traffic lights with a lengthy red phase. Even after just
30 - 40 seconds you will have saved more fuel than that is needed when
you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal
operating temperature. Wear-and-tear and pollutant emissions, though,
are particularly high in the warming-up phase. This is why you should
drive off right after starting the engine. Do avoid high engine revolutions
at this time, however.
Regular servicing
A poorly tuned engine consumes an unnecessarily high
amount of fuel.
Having your vehicle serviced regularly at a Škoda Dealer enables you to
satisfy one of the requirements for economical motoring even before you
set off on your journey. Keeping your vehicle properly serviced not only
has a positive effect on the safety of your vehicle and maintaining its
value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10%
higher than normal.
The foreseen maintenance work should be undertaken exactly according
to the Service Schedule by a Škoda dealer.
Also check the oil level after refueling. Oil consumption is dependent to
a considerable extent on the load and speed of the engine. Oil consump- tion could be as high as 0.5 litres/1 000 km depending on your style of
driving.
It is quite normal that a new engine has a higher oil consumption at first,
and reaches its lowest level only after a certain running in time. It is there-
fore not possible to correctly assess the oil consumption of a new vehicle
until after you have driven about 5 000 km.
For the sake of
the environment
•You can achieve additional improvements in your fuel economy by
using high-lubricity oils.
•Check the ground below your car at regular intervals to detect any
leakages in good time. Please have your vehicle inspected by a Škoda
dealer if you find any stains caused by oil or other fluids on the floor.

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.

Fuel

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 206, fig. 156 .
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 206.
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 205, “Biofuel”.

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.

Inspecting and Replenishing209
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
– Allow the bonnet to drop from a height of about 30 cm into the
lock - bonnet do not press down on it!
The bonnet is held in the opened position by a pressurized gas spring.
WARNING
•Never open the bonnet if you see that steam or coolant is
flowing out of the engine compartmen t - risk of scalding! 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 properly after closing the bonnet.
•Stop your vehicle immediately while driving if you notice that
the lock is not properly engaged and close the bonnet properly -
risk of an accident!
Caution
•Never open the bonnet using the handle - danger of causing damage.
•Before opening the bonnet, ensure that the arms of the windscreen
wipers are correctly in place against the windscreen. Otherwise, there is
a risk of damage to the paintwork.
Working in the en gine 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 compartment 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 scalding! 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 manual gearbox, move the gear-
shift 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.
•Do not touch any hot engine parts - risk of burns!
•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 expansion bottle as long as
the engine is still warm. The cooling system is pressurized!
