„Diesel fuel mixture according to standard CSN 65 6508 from
02/2003 contains diesel fuel according to standard DIN EN 590 and a
concentration of biofuel (rape oil methyl ester) according to standard
DINEN14214 in the following two concentrations:
„5% share of biofuel RME according to the standard DINEN14214
- Denomination SMN 5,
„30% share of biofuel RME according to the standard
DINEN14214 - Denomination SMN 30.
The same principles apply for the diesel fuel mixture as for the biofuel
⇒ page 243.
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 245, “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*
The possibility to refuel with biofuel only applies to vehi-
cles, which have been adapted at the factory for its use.
Biofuel (RME rape oil methyl ester fuel) must comply with the DIN EN
14 214 ⇒ .
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.
We recommend refuelling with diesel fuel at temperatures below -10°C.
Biofuel conforming to DIN EN 14 214 can be mixed in any desired ratio
with diesel fuel conforming to the standard DIN EN 590.

Engine oil specifications for models with flexible service intervals
(QG1)
Caution
Only the above-mentioned oils may be used on vehicles with flexible
service intervals (QG1). We recommend always refilling with oil of the
same specification since this will maintain the properties of the oil. In
exceptional cases, you must top up only once engine oil complying with
Specification VW 502 00 (only for petrol engines) or Specification VW 505
01 (only for diesel engines) to maximum 0.5 litres. You must not use other
engine oils - risk of engine damage!
Note
•Before a long drive we recommend that you purchase and carry with
you engine oil which complies with the specification for your vehicle.
Consequently, you will always have the correct engine oil for refilling.
•We recommend using a preservative from the Škoda original accesso-
ries offered by your Škoda dealer.
•For further information - see Service shedule.
Inspecting the engine oil level
The dipstick indicates the level of oil in the engine.
Checking the oil level
– Park the vehicle on a horizontal surface.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 248.
– 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.

Changing engine oil
The engine oil must be changed at the intervals stated in the Service
schedule or according to the service interval indicator ⇒page 16.
WARNING
•Only carry out the engine oil change, if you have the required
professional knowledge!
•Read and observe the warning notes ⇒page 248, “Working in
the engine compartment” before working in the engine compart-
ment.
•Let the engine cool down - risk of burning from hot oil.
•Wear an eye protection - risk of caustic burns due to oil
splashes.
•Oil is toxic! Store old oil in a safe place out of the reach of chil-
dren and unauthorized persons until you dispose of it properly.
Caution
You must not pour any additives into the engine oil - risk of engine
damage! Damage, which results from such product, are excluded from the
warranty.
For the sake of the environment
•You must on no account pour oil into the ground or into the sewage
system.
•In view of the problems involved in properly disposing of old oil, the
material, equipment and the knowledge required for such work, we recom-
mend that you have the oil and oil filter change carried out by your Škoda
dealer.
Note
After your skin has come in contact with the oil, you must thoroughly wash
your skin.
Cooling system
Coolant
The job of the coolant is to cool the engine.
The cooling system does not require any maintenance under normal oper-
ating conditions. The coolant consists of water with a concentration of
coolant additive of 40 %. This mixture not only provides antifreeze protec-
tion 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 coun-
tries 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 iIf 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 %.

Inspecting and Replenishing255
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
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
expansion bottle which is completely free of leaks if the coolant boils as a
result of overheating and is forced out of the cooling system.
WARNING
Read and observe the warning notes ⇒page 248, “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 overheating 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 ⇒fig. 194 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 253, “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 he alth. 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
immediately with clear water and contact a doctor as soon as
possible.
•You should also consult a doctor without delay if you have inad-
vertently swallowed coolant.

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 situation where the brake fluid level is too low is indi-
cated by the warning light
 lighting up in the instrument cluster
⇒ page 40. In this case stop the car immediately and do not drive any
further! Contact a Škoda Dealer to obtain professional assistance.
WARNING
•Read and observe the warning notes ⇒page 248, “Working in
the engine compartment” before working in the engine compart-
ment.
•If the fluid level has dropped below the “MIN” marking, do not
drive any further - risk of accident! Contact a Škoda dealer to obtain
professional assistance.
Replacing brake fluid
Brake fluid absorbs moisture. This causes the fluid to absorb moisture
from the surrounding air over a period of time. Excessive water in the
brake fluid may be the cause of corrosion in the brake system. The water
content also lowers the boiling point of the brake fluid. This is why brake
fluid must be replaced every two years.
One may only use new genuine brake fluid from Škoda Auto. The specifi-
cation for the brake fluid is “FMVSS 116 DOT 4”.
We recommend that you have the brake fluid replaced by a Škoda dealer
as part of an Inspection Service.
WARNING
•Using old brake fluid can result in severe stress on the brakes
because of the formation of vapour bubbles in the brake system.
This greatly impairs the braking efficiency and thus also the safety
of your vehicle.
•Brake fluid is toxic! It must therefore be kept safely in closed
original containers and well away from children and unauthorized
persons.
Caution
Brake fluid damages the paintwork of the vehicle.
For the sake of the environment
In view of the problems involved with proper disposal of brake fluid, the
special tools and the professional knowledge required, you should have
the brake fluid replaced by a Škoda dealer.

•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! Imme-
diately replace a damaged battery.
Caution
•You must only disconnect the battery if the ignition is switched on,
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.
•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 envi-
ronment - contact your specialist garage regarding disposing of the
battery.
Note
Please also refer to the guidelines ⇒page 261, “Disconnecting and recon-
necting the battery”, also after connecting the battery.

– You can now plug the mains cable of the charger into the
power socket and switch on the charger.
– When charging is completed: switch the charger off and unplug the mains cable from the power socket.
– Only then should you disconnect the terminal clamps of the charger.
– Reconnect the cables to the battery (first of all “positive”, then “negative”).
It is not normally necessary to disconnect the cables of the battery if you
recharge the battery using low amperages (as for example from a mini-
charger ). Please also refer to the instructions from the charger manufac-
turer.
A charging current of 0.1 of the total battery capacity (or lower) is that
which should be used until full charging is achieved.
It is, however, necessary to disconnect both cables before charging the
battery with high amperages, so-called “ quick-charging”.
“Quick-charging” a battery is dangerous ⇒ in “Working on the battery”
on page 258. It requires a special charger and appropriate knowledge. We
therefore recommend that you have your battery quick-charged only by
your Škoda dealer.
A discharged battery may already freeze at temperatures just below 0°C
⇒ . We recommend that you no longer use a battery which has thawed
out because the casing of the battery may be cracked through the forma-
tion of ice and this would allow battery electrolyte to flow out.
The vent plugs of the battery should not be opened for charging.
WARNING
Never charge a frozen or thawed battery - risk of explosion and
caustic burns. Replace a frozen battery.
Disconnecting and reconnecting the battery
On disconnecting and reconnecting the battery the following functions are
initially deactivated or are no longer able to operate fault-free:
We recommend having the vehicle checked by a Škoda dealer to ensure
full functionality of all electrical systems.
Replacing the battery
You should only replace a battery with a new battery of the same capacity,
voltage (12 V), amperage and of the same size. Škoda dealers have a
range of suitable batteries available.
