Changing engine oilThe engine oil must be changed at the intervals stated in the Service schedule or according to the service interval indicator
⇒page 20, “Service Interval Display”.
WARNING
•
Only carry out the engine oil change, if you have the required profes-
sional knowledge!•
Read and observe the warning notes
⇒page 223, “Working in the engine
compartment” before working in the engine compartment.•
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 children and
unauthorized persons until you dispose of it properly.
Caution
You must not pour any additives into th
e 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 prop
erly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you have the oil and oil filter change carried
out by an authorised Škoda Service Partner.
Note
After your skin has come in contact with
the oil, you must thoroughly wash your
skin.
Cooling systemCoolant The job of the coolant is to cool the engine.The cooling system does not require an
y maintenance under normal operating
conditions. The coolant consis
ts 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 an
tifreeze protection tails off above that
concentration. Vehicles exported to countri
es 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 concentr
ation of coolant additive should be at
least 50 %. Coolant The cooling system is factory-filled with c
oolant (purple in colour), which complies
with the specification TL-VW 774 G. We recommend that you use the same co
olant additive - G12 PLUS-PLUS (purple
in colour) for topping up the system. Please contact an authorised Škoda Service Partner if you have any questions regarding the coolant or if you wish
to fill up with a different coolant.
An authorised Škoda Service Partner can
also supply you with the correct coolant
additives.

Caution
•
Other coolant additives may cause operational problems which, in partic-
ular, involves significantly redu
cing the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th
is, result in major engine damage.
Inspecting the coolant levelThe coolant expansion bott
le is located in the engine compartment on
the right. – Switch the engine off. – Open the bonnet
⇒
page 223, “Working in the engine compartment”.
– Check the level of coolant in
the coolant expansion bottle
⇒
fig. 204
.
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 38. 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 leak
s 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 223, “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
⇒
fig. 204
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 replenishi
ng the system, must comply with one
specific specification
⇒page 226, “Coolant”. Do not use an alternative additive if
the coolant additive G12 PLUS is not available in exceptional cases. Just top up the
