The fuel consumption can naturally also be
influenced by factors which are beyond
the driver's control. It is,
for example, normal for the fu
el consumption to increase
in winter and under worsened
conditions such as poor road conditions, towing a
trailer, etc. The technical requirements for low fuel
usage and economic efficiency of the
vehicle have already been built into the ve
hicle at the works.
Special attention has
been given to minimising ne
gative effects on the environment. It is necessary to
take note of the guidelines given in this
chapter in order to make best use of these
characteristics and to maintain their effectiveness. The optimal engine speed should be obtained when accelerating, in order to avoid a high fuel consumption an
d resonance of the vehicle.
Looking ahead when driving A vehicle's highest fuel consumption occurs it accelerates.Avoid accelerating and brakin
g unnecessarily. If you drive
with forsight you will not
need to brake so often and will also then
not have to accelerate so much. Let your
vehicle coast to a stop, for example, if this
is possible, when you see that the next
set of traffic lights is at red.Shifting gears and saving energy Shifting up early saves on fuel.
Manual gearbox – Drive no more than about one length of your vehicle in first gear. – Always shift up into the next higher gear at approx. 2 000 to 2 500 revs. Automatic gearbox – Depress the accelerator pedal
slowly
. Do not depress it beyond the
kickdown position, however.
An effective way of achieving good
fuel economy is to shift up
early
. You will
consume more fuel if you drive at unnecessa
rily high revolutions in any given gear.
The
⇒fig. 194
shows the ratio of fuel consumption to the speed of your vehicle in
the relevant gears. Fuel consumption in 1st
gear is the highest, while that in 5th or
the 6th gear is the lowest. Only depress the accelerator pedal slowly if
your vehicle is fitted with an automatic
gearbox in order to automatically select an economic driving programme. You will achieve good fuel economy by shifting
up early and shifting down late.

Avoiding full throttle Driving more slowly means saving fuel.Sensitive use of the accelera
tor will not only significantly reduce fuel consumption
but also positively influence environmen
tal pollution and wear of your vehicle.
You should avoid fully exploi
ting the top speed of your vehicle wherever possible.
Fuel consumption, pollutant emissions and vehicle noises increase disproportion- ally at high speeds. The
⇒fig. 195
shows the ratio of fuel consumption 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 moto
ring even before you set off on your
journey. Keeping your vehicle properly servic
ed 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 consum
ption 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.

Technical Data
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. 15 - 20 litres/100 km of fuel immediately after starting. Fuel co
nsumption drops to 10 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. 196
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 is particularly in town traffic, when one
is accelerating quite often, that the vehicle
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 10% more fuel th
an normal at a speed of 100 - 120 km/h,
even when you are not carr
ying a load on the roof.
Saving electricity Generating electricity 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 consumptionIf 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.

•
Use of water-soluble paints.
Motoring abroadGeneral 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
o n l y b e a b l e t o m a ke l i m i te d re p a i rs . Š ko d a A u to i n t h e C z e c h R e pu b l i c a n d re l e v a n t importers are happy to provide information
about technical aspects of the vehicle,
required maintenance work and possibilities for getting repairs done.Unleaded petrolA vehicle fitted with a petrol engine must always be refuelled with unleaded petrol ⇒ page 202. The automobile associations can provide you with information regarding the locations of filling stations which offer unleaded petrol.HeadlightThe 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 authorised Škoda Service Partner.

Taking care of your vehicle and cleaning the vehicle
216
Engine compartmentGood 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. The authorised 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 223, “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 vehiclePlastic parts, artificial leather and clothsYou 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 seatsDo
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.

Technical Data
FuelPetrolGrades of petrolThere are various grades of petrol. Please read
⇒page 267, “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 220, fig. 199
.
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 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. 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 whic
h 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 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 220, “Refuelling”.
Caution
•
Filling the tank even only once with lead
ed petrol will result in the catalytic
converter being destroyed.•
Operating the engine with petrol of a lo
w octane number can result in engine
damage at high revolutions or severe engine loading.DieselDiesel fuelYour 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 220, “Refuelling”.
Caution
•
Use fuel which complies with the standard
DIN EN 590
. 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 winterWinter-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 char
acteristic. The authorised Škoda Service
Partners 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 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.

Closing fuel filler cap – Screw on the fuel filler cap by turning it to the right until it is heard to
click.
– Close the fuel filler flap until it locks.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 219.
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.
