Instruments and Indicator/Warning Lights15
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
The fuel tank has a capacity of about 55 litres. The warning symbol
 in
the instrument cluster lights up when the pointer reaches the reserve
marking. There are now about 7 litres of fuel remaining in the tank. This
symbol is a reminder for you, that you must refuel.
The following will be displayed in the information display*: PLEASE REFUEL
A peep sounds as an additional warning signal.
Caution
Never run the fuel tank 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.
Counter for distance driven
The distance which you have driven with your vehicle is shown in kilome-
tres (km). On certain model versions, the readout is shown in “miles”.
The kilometer counter for distance driven is shown on the display when
the ignition is switched off. The trip counter for distance driven is shown
on the display after switching on the ignition. You can then switch over to
the counter display with the reset button.
Reset button
By briefly pressing the reset button ⇒page 13, fig. 2 you can switch
over from the trip counter to the kilometer counter. In order to recognize
which counter for the distance driven is shown on the display at that
moment, trip ⇒ fig. 3 appears after the trip counter.
If you hold the reset button pressed for about 1 second, the trip counter
is set back to zero.
If you hold the reset button pressed for longer than 3 seconds, a
display regarding the kilometers still to be driven and the days until the
following service interval (for this the trip counter is not set back) appears.
Fault display
dEF will appear as a constant text in the display field of the counter for
distance driven if there is a fault in the instrument cluster. Have the fault
rectified as soon as possible by a specialist workshop.
Warning against excessive speeds*
An acoustic warning signal will sound when the vehicle speed exceeds
120 kilometres per hour. The acoustic warning signal will switch off again
when the vehicle speed goes below this speed limit.
This function is only valid for some countries.
WARNING
Never seek to adjust the trip counter for distance driven while
driving for safety reasons!

Starting-off and Driving111
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
WARNING
•When driving, the ignition key must always be in the position
(ignition switched on) without the en gine running. This position is
indicated by the warning lights coming on. If this is not the case, it
could result in unexpected locking of the steering wheel - risk of
accident!
•Do not withdraw the ignition key from the lock until the car has
come to a stop. The steering lock can engage immediately - risk of
accident!
•Always withdraw the ignition key if you are going to leave the
vehicle, even for a short time. This is particularly important if chil-
dren are left in the vehicle. The children might otherwise start the
engine or operate electrical equi pment (e.g. power windows) - risk
of injury!
Starting the engine
General
You can only start the engine only using an original ignition
key.
•Place the gearshift lever into neutral and put on the handbrake firmly
before starting the engine.
•The clutch pedal should be fully depressed when starting the engine
which means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be
damage to the starter. The engine running noises may louder at first be louder for a short time
after starting the cold engine until oil pressure can be built up in the
hydraulic valve clearance compensation. This is quite normal and is not
an operating problem.
If the engine does not start ...
You can use the battery of another vehicle as a jump-start aid
⇒
page 243.
It is only possible to tow-start vehicles fitted with a manual gearbox. The
tow-starting distance must not be more than 50 metres ⇒page 247.
WARNING
•Never run the engine in non ventilated or enclosed areas. The
exhaust gases of the engine contain besides the odorless and
colourless carbon monoxide a poisonous gas - hazard! Carbon
monoxide can cause unconsciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), if the
engine is not running. If the starter is immediately operated after switching
off the engine, the starter or the engine can be damaged.
•Avoid high engine revolutions, full throttle and high engine loads as
long as the engine has not yet reached its normal operating temperature
- risk of damaging the engine!
•Vehicles which are fitted with an exhaust gas catalytic converter
should not be tow-started over a distance of more than 50 metres.

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 205, “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 214,
“Replenishing engine oil”. – Do not tow-start the vehicle over a distance of more than 50
metres ⇒page 247, “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 specialist garage. 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.

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 must first have reached their optimal
operating temperature in order to effectively reduce fuel consumption
and pollutant emissions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel
immediately after starting. Fuel consumption drops to 10 litres/100 km
after just 1 kilometre. The engine reaches its operating temperature
(outside temperature and engine dependent) only after about 4 to 10 kilo-
metres 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. 150 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 consump-
tion means that it is worth taking a look in the luggage compartment to
avoid transporting 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 conven-
ience, although you no longer need it. The increased aerodynamic drag of

Taking care of your vehicle and cleaning the vehicle
202
Underbody protection
The underside of your vehicle 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 intervals - this
is best done at the beginning and end of the winter - and to touch up any
damaged areas.
Škoda Service Partners have suitable spray products available as well
as the necessary equipment and are familiar with the instructions for use.
We therefore recommend to have repairs and additional corrosion protec-
tion measures preferably carried out by a Škoda Service Partner.
WARNING
Never use additional underbody protection or corrosion-protection
agents for the exhaust pipes, catalytic converters or heat shields.
Such substances might ignite when driving - 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 remove wax - a risk of fire!
Engine compartment
Good corrosion protection is very important, 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 cleaning agents 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 210.
•Let the engine cool down before cleaning the engine compart-
ment.
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

Fuel205
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
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 207, fig. 152 .
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 DIN 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 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 neither
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 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 207.
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 than that
required can result in engine damage at high revolutions or severe engine
loading.
Diesel
Grades of diesel
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 DIN EN 590.

– Unlock the fuel filler cap on the fuel filler tube to the left using the vehicle key.
– Unscrew the fuel filler cap anti-clockwise and place the fuel filler cap from above on the fuel filler flap ⇒page 207,
fig. 152 .
Closing fuel filler cap
– Screw on the cap by turning it to the right until it is heard to lock.
– Lock the fuel filler cap on the fuel filler tube to the right using the vehicle key.
– Press the fuel tank flap closed.
The correct grades of fuel for your vehicle are stated on a sticker affixed
to the inside of the fuel filler flap. Further information on fuel ⇒page 205.
The fuel tank has a capacity of about 55 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
damaged in the event of an accident and fuel may leak out.
Caution
•Remove any fuel which has spilled onto the paintwork of your vehicle
immediately. This particularly applies to biodiesel - risk of paint damage!
•Vehicles fitted with catalytic converter should 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.
For the sake of
the environment
The fuel tank is full just as soon as the pump nozzle switches off for the
first time, provided the nozzle has been operated properly. You should not
continue refuelling - otherwise the expansion chamber in the fuel tank will
also be filled with fuel. Fuel might flow out of the tank when it heats up.
