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 %.

Coolant
The cooling system is filled at the works with coolant (purple in colour),
which complies with the specification TL-VW 774 F.
We recommend that you use the same coolant additive - G12 PLUS
(purple in colour).
Please contact your Škoda dealer if you have any questions regarding the
coolant or if you wish to fill up with a different coolant.
Your Škoda dealer can also supply you with the correct coolant additives.
Caution
•Other coolant additives may cause operational problems which,
in particular, 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 level
The coolant expansion bottle is located in the engine compart-
ment on the right.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 248.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 194 . 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.
If the coolant level in the reservoir is too low, this is indicated by the
warning light in the instrument cluster  ⇒ page 35. We nevertheless

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.

Caution
Do not continue your journey if for some reason it is not possible
under the conditions prevailing to top up with coolant. Switch of the
engine and contact and obtain professional assistance from a specialist
garage.
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.
The radiator fan
The radiator fan may switch on suddenly.
The radiator fan is driven by an electric motor and controlled 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 compart-
ment that the fan may switch on suddenly - risk of injury!
Brake fluid
Inspecting the brake fluid level
The 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 compart-
ment.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 248.
– Inspect the brake fluid level in the reservoir ⇒fig. 195 . The
level must be between the “MIN” and “MAX” markings.

Caution
•When unlocking and locking the fuse cover, it must be pressed on the
sides to the box, otherwise damage can occur to the locking mechanism.
•Carefully position the fuse cover in the engine compartment. If the
cover was not correctly positioned, water can get into the fuses and this
results in a damage to the vehicle!
