Technical Data
FuelPetrolGrades of petrolThere are various grades of petrol. Please read the chapter ⇒page 233, “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 182, fig. 173.
A distinction is made between unleaded and leaded petrol. All Škoda vehicles 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.
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 fuel which
complies with the standard EN 228.
You can find further information on refuelling ⇒page 182.
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 lower octane number than that prescribed
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
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 fuel which complies with the standard EN 590. 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.
•
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.

Engine oilCheck engine oil level
The dipstick indicates the level of oil in the engine.Checking the oil level
– Ensure that the vehicle is positioned on a level surface and the engine
has reached its operating temperature.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 185.
– Wait a few minutes and pull out the oil dipstick ⇒.
– Wipe off the dipstick with a clean cloth and insert it again fully.
– Then withdraw the dipstick again and read off the oil level.
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. The optimum lies in the middle of the
range .
Oil level within range
–You must top up the oil. It is sufficient, once this is done, to keep the
oil level within range .
It is normal for the engine to consume oil. The oil consumption 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 consumption 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 33 whether the oil
level is too low. In this case, check the oil level as soon as possible. Top up with an
appropriate quantity of oil.
WARNING
Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.
Caution
•
The oil level must on no account extend 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 the engine off and obtain profes-

Cooling systemCoolant
The job of the coolant is to cool the engine.The cooling system does not require any maintenance under normal operating
conditions. The coolant consists of water with a concentration of coolant additive
of 40 %. This mixture not only provides antifreeze protection down to -25°C but
also protects the cooling and heating system from corrosion. It also prevents the
formation of scale and significantly increases the boiling point of the coolant.
You must therefore not reduce the concentration of antifreeze agent in the coolant
by adding water, also not during the summer months or in countries with a warm
climate. The concentration of coolant additive in the coolant must be at least
40%.
You can increase the amount of antifreeze in the coolant if a higher concentration
of antifreeze is necessary for climatic reasons but only up to 60% (antifreeze
protection down to approx. -40°C). The antifreeze protection tails off above that
concentration.
Vehicles exported to countries with a cold climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant which offers antifreeze protection down to
about -35°C. In these countries the concentration of coolant additive should be at
least 50 %.
Coolant
The cooling system is factory-filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the antifreeze agent G12 PLUS - PLUS (purple in
colour) for topping up the system.
We recommend that you contact a specialist garage if you have any questions
regarding the coolant or if you wish to fill up with a different coolant.
A specialist garage can also supply you with the correct coolant additives.
Caution
•
Other coolant additives may cause operational problems which, in partic-
ular, involves significantly reducing the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of this, result in major engine damage.
Inspecting the coolant levelThe coolant expansion bottle is located in the engine compartment on
the right.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 185.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 179.
The coolant level when the engine is cold must lie between the “MIN”
and “MAX” markings. The level may also rise slightly above the
“MAX” marking when the engine is warm.

Inspecting and replenishing 190If the coolant level in the reservoir is too low, this is indicated by the warning light
in the instrument cluster
 ⇒page 32. We nevertheless recommend inspecting
the coolant level directly at the reservoir from time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. You
should not merely top up the coolant in the reservoir. It is also important to have
the cooling system inspected without delay by a specialist garage.
Losses can only occur through the pressure relief in the cap of the coolant expan-
sion bottle which is completely free of leaks if the coolant boils as a result of over-
heating and is forced out of the cooling system.
WARNING
Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as soon as possible if the source of over-
heating itself cannot be determined and removed, since there may be grave
damage to the engine.Replenishing the coolant– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir
⇒page 189, fig. 179 and unscrew the cap carefully by turning it to the
left ⇒.
– Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with one
specific specification ⇒page 189, “Coolant”. Do not use an alternative additive if
the coolant additive G12 PLUS is not available in exceptional cases. Just top up the
system with water and as soon as possible arrange adjustment to correct the mixing
ratio of water and coolant additive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill up over the “MAX” marking! Excess coolant which is heated up is forced
out of the cooling system through the pressure relief valve in the cap of the coolant
compensation bottle.
Wait until the engine has cooled down for a system which has suffered a major loss
of coolant before pouring in coolant. This is necessary to avoid engine damage.
WARNING
•
The cooling system is pressurized! Do not open the cap of the coolant
expansion bottle if the engine is still hot - risk of scalding!
•
The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the
health. It is important, therefore, to always safely store any coolant additive
in its original container out of the reach of children - risk of poisoning!
•
If any splashes of coolant get into your eyes, rinse out your eyes immedi-
ately with clear water and contact a doctor as soon as possible.
•
You should also consult a doctor without delay if you have inadvertently
swallowed coolant.Caution
Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with coolant. Switch the engine off and obtain
professional assistance from a specialist garage, otherwise it could lead to severe
engine damage.

For the sake of the environment
Do not re-use coolant if it is necessary to drain the coolant in the system. It should
be collected and disposed of in compliance with environmental protection
regulations.Radiator fan
The radiator fan may switch on suddenly.The radiator fan is driven by an electric motor and controlled by a thermostat
according to the coolant temperature.
The radiator fan may continue running for up to 10 minutes after the engine has
been switched off - even if the ignition is also off. It may also switch on suddenly
after a certain time, if•
the coolant temperature has risen because of an accumulation of heat or
•
the warm engine compartment is heated up additionally by strong sunlight.
WARNING
You must therefore be aware when working in the engine compartment that
the fan may switch on suddenly - risk of injury!
Brake fluidInspecting the brake fluid levelThe brake fluid reservoir is located on the left of the engine compartment.
The brake fluid reservoir on right-hand steering models is positioned on
the other side of the engine compartment.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 185.
– Inspect the brake fluid level in the reservoir ⇒fig. 180. The level must
be between the “MIN” and “MAX” markings.A slight drop in the fluid level results when driving due to normal wear-and-tear
and automatic adjustment of the brake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid level
drops significantly within a short time or if it drops below the “MIN” marking. A situ-
ation where the brake fluid level is too low is indicated by the warning light

lighting up in the instrument cluster ⇒page 36. In this case stop immediately and
do not drive any further! Obtain professional assistance.

a specialist garage.
There is a risk of injuries, scalding, accidents and burns when carrying out any work
on the battery and on the electrical system. For this reason, it is essential to comply
with the warning instructions ⇒ stated below and with the general applicable
rules of safety.
WARNING
•
The battery acid is strongly corrosive and must, therefore, be handled
with the greatest of care. Always wear protective gloves, eye and skin
protection when handling batteries. Corrosive fumes in the air irritate the
air passages and lead to conjunctivitis and inflammation of the air passages
in the lungs. Battery acid corrodes dental enamel and creates deep wounds
after contact with the skin which take a long time to heal. Repeated contact
with diluted acids causes skin diseases (inflammations, ulcers, slin cracks).
Acids coming into contact with water are diluted accompanied by significant
development of heat.
•
Do not tilt the battery otherwise battery electrolyte may flow out of the
battery vent openings. Protect the eyes with safety glasses or a shield! There
is the danger of suffering blindness! If any battery electrolyte gets into your
eye, rinse out your eye immediately with clear water for several minutes.
Contact a doctor without delay.
•
Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. Contact a
doctor immediately if you swallow battery electrolyte.
•
Keep batteries out of the reach of children.
•
Hydrogen is released when you charge a battery and a highly explosive
gas mixture is produced. An explosion can be caused through sparkling over
during unclamping or loosening of the cable plug while the ignition is on.
•
Bridging of the poles will create a short circuit (e.g. through metal
objects, cables). Possible consequences of a short circuit: Melting of lead
struts, explosion and burning of the battery, jets of acid spurting out.
•
It is prohibited to work with a naked flame and light, to smoke or to carry
out any activities which produce sparks. Avoid creating sparks when
working with cables and electrical devices. Strong sparking represents a risk
of injury.
•
Before carrying out any work on the electrical system, switch off the
engine, the ignition as well as all electrical components and disconnect the
negative cable (-) on the battery. If you wish to replace a bulb it is sufficient
to switch off the appropriate light.
•
Never charge a frozen or thawed battery - risk of explosion and caustic
burns! Replace a frozen battery.
•
Never use a battery which is damaged - risk of explosion! Immediately
replace a damaged battery.Caution
•
You must only disconnect the battery if the ignition is switched off, otherwise
the electrical system (electronic components) of the vehicle may be damaged.
When disconnecting the battery from the electrical system of the vehicle, first
disconnect the negative terminal (-) of the battery. Then disconnect the positive
terminal (+).
•
When reconnecting the battery, first connect the positive terminal (+) and only
then the negative terminal (-) of the battery. You must on no account connect the
cables wrongly - risk of a cable fire.
•
Ensure that battery acid does not come into contact with the vehicle body
otherwise damage could occur to the paintwork.WARNING (continued)

Inspecting and replenishing 194•
Do not place the battery in direct daylight in order to protect the battery
housing from the effects of ultra-violet light.For the sake of the environment
A removed battery is a special type of waste which is harmful to the environment -
contact your specialist garage regarding disposing of the battery.
Note
•
Please also refer to the guidelines ⇒page 196, “Disconnecting and recon-
necting the battery”, also after connecting the battery.
Battery with a two-tone indicatorAn indicator for the electrolyte level, the so-called magic eye ⇒fig. 183, is located
on the top of the battery. The indicator changes its colour in line with the electrolyte
level in the battery.
Air bubbles can influence the colour of the indicator. For this reason carefully knock
on the indicator before carrying out the check.•
Black colour - electrolyte level is correct.
•
Colourless or light yellow colour - electrolyte level too low, the battery must be
replaced.Batteries, which are more than 5 years old, must be replaced. We recommend you
have the battery checked or replaced by a specialist garage.
Caution
If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge because certain electrical components consume electricity (e.g. control
units) also in idle state. You can prevent the discharging of the battery by discon-
necting the negative terminal or charging the battery constantly with a very low
charging current. Please also refer to the notes when working on the battery ⇒
in “Working on the battery” on page 192.
Note
•
Batteries with two-tone indicator, which are mounted as of factory, are marked
with a code which always begins with 5K0. The exact marking can be e.g.
5K0 915 105 D.
•
Replacement batteries with two-tone indicator, which were obtained from
Škoda original accessories, are marked with the code 000 915 105 Dx, whereby
“x” stands for a variable. The exact marking can be e.g. 000 915 105 DB.
Battery with a three-tone indicatorAn indicator for the electrolyte level and the charge state, the so-called magic eye
⇒fig. 183, is located on the top of the battery. The indicator changes its colour in
line with the charge state and the electrolyte level in the battery.
Air bubbles can influence the colour of the indicator. For this reason carefully knock
on the indicator before carrying out the check.•
Green colour - the battery is adequately charged.
•
Dark colour - the battery has to be charged
•
Colourless or yellow colour - electrolyte level too low, the battery must be
replaced.
Batteries, which are more than 5 years old, must be replaced. We recommend you
have the battery checked or replaced by a specialist garage.
