Avoiding full throttle
Driving more slowly means saving fuel.
Sensitive use of the accelerator will not only significantly reduce fuel consumption
but also positively influence environmental pollution and wear of your vehicle.
You should avoid fully exploiting the top speed of your vehicle wherever possible.
Fuel consumption, pollutant emissions and vehicle noises increase disproportion-
ally at high speeds.
The ⇒fig. 167 shows the ratio of fuel consumptio n to the speed of your vehicle.
You will cut your fuel consumption by half if you only make use three-quarters of
the possible top speed of your vehicle.
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 length y 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 em issions, 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 re
volutions at this time, however.
Regular servicing
A poorly tuned engine consumes an unnecessarily high amount of
fuel.
Having your vehicle serviced regularly at a specialist garge 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 fu el consumption which is 10% higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refueling. Oil consumption is dependent to a consid-
erable extent on the load and speed of the engine. Oil consumption 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 ha s a higher oil consumption at first, and
reaches its lowest level only after a certain running in time. It is therefore not
possible to correctly assess the oil cons umption 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 regula r intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garge if you find any
stains caused by oil or other fluids on the floor.

Avoid driving short distances
Short distances result in an above-average high fuel consumption.
– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter mu st first have reached their optimal operating
temperature in order to effectively reduce fu el consumption and pollutant emis-
sions.
The cold engine vehicle consumes approx. 20 - 30 litres/100 km of fuel immediately
after starting. Fuel consumption drops to 15 litres/100 km after just 1 kilometre. The
engine reaches its operating temperat ure (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then
stabilizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
⇒ fig. 168 shows the different fuel consumptions for the same distance, on the one
hand at +20°C and on the other hand at -10°C. Your vehicle has a higher fuel
consumption in winter than in summer.
Checking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all times. The
rolling resistance will be increased if the tyre filling pressure is too low. This will not only increase fuel consumption but also
tyre wear and the driving behaviour will
worsen.
Always check the inflation pressure of the tyres when cold.
Do not drive with winter tyres all year round for this costs about 10 % more fuel.
Winter tyres are also louder.
No unnecessary ballast
Transporting ballast costs fuel.
The fact that every kilogram of extra weight increases your fuel consumption
means that it is worth taking a look in the luggage compartment to avoid trans-
porting any unnecessary ballast.
It i s par ti cula rl y in town traff ic, when one i s accel era ti ng qui te often, tha t the v ehicle
weight will have a significant effect upon the fuel consumption. A rule of thumb
here is that an increase in weight of 100 kilograms will cause an increase in fuel
consumption of about 1 litre/100 kilometres.
You may frequently also leave a roof rack fitted on just out of convenience,
although you no longer need it. The incr eased aerodynamic drag of your vehicle
causes it to use about 1 l more fuel than normal at a speed of 100 - 120 km/h, even
when you are not carrying a load on the roof.
Saving electricity
Gen era ti n g e l ect r icity costs fuel.
– Switch off electrical components as soon as you no longer need them.
When the engine is running, the alternator generates and supplies electrical power.
The greater the load on the alternator as a result of having a large number of elec-
trical components switched on, the more fuel will be consumed for operating the
alternator.

Keeping a log of your fuel consumption
If you really wish to keep 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 should reflect on how, where
and in what conditions you have driven the vehicle since you last refuelled.
Environmental compatibility
Environmental protection has played a major 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
Trade-in and recycling of old cars
Škoda Auto meets the requirements of the brand and its products regarding envi-
ronment and ressource protection. All new Škoda vehicles can be utilized up to
95 % and always
3) be returned. In a lot of countries sufficient trade-in networks
have been created, where you can trade-in your vehicle. After you trade-in your
vehicle, you will receive a confirmation st ating the recycling in accordance with
environmental regulations.
Vehicles with special built-on types
Technical documents regarding changes carrie d out on the vehicle must be kept by
the vehicle user, in order to hand over later to the old car user. This ensures the
recycling in accordance with environmental regulations.
Motoring abroad
General
Other circumstances may exist abroad.
It is also possible, in certain countries , that the Škoda 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 make limited repairs. Škoda Auto a.s. in 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 163. 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 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.
Headlight stickers can be obtained as a spare part from the Skoda Service Partners.
Headlights with Xenon lamps are designed for driving in countries with traffic on
the right or on the left. Have this do ne always at a Škoda Service Partner.
Note
You can obtain further information regardin g masking over or converting the head-
lights from your Škoda Service Partner.
Avoiding damage to your vehicle
When driving on poor roads and lanes or when driving over kerbstones, steep
ramps etc., you must pay particular attent ion to ensuring that any low-slung parts
of the vehicle, such as spoiler and ex haust, 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.

Taking care of your vehicle and cleaning the vehicle
178
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 entire engine
compartment before and after the salt spreading period, in order to prevent the salt
from being destructive.
Škoda Service Partners have the cleani ng agents recommended by the manufac-
turer and also the required equipment.
WARNING
•It is necessary to observe the guidelines given in the chapter before
working on the engine compartment ⇒page 185.
•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 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, 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.
Severe soiling
– Clean severely soiled areas with a cloth dipped in a mild soapy solu- tion (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.

Fuel
Petrol
Grades of petrol
There are various grades of petrol. Please read ⇒page 227 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 182, fig. 170 .
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.
•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 circumstances also use unleaded regular
petrol of 91 RON in the event that neithe r unleaded premium petrol of 98 RON nor
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 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 182, “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
Type of diesel
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 182, “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.

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
Refuelling procedure
Opening the fuel filler cap
– Unlock the fuel filler flap with the switch in the driver door ⇒page 35.
– Open the fuel filler flap fully.

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
•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.
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 arro w in order to unlock the fuel filler
flap ⇒fig. 171 .
WARNING
When unlocking the fuel filler flap manually, pay attention to sharp edges of
the body - risk of injury!
