WARNING
•
Avoid dripping oil onto hot parts of the engine when topping up will oil -
a risk of fire!•
Read and observe the warning notes
⇒page 225, “Working in the engine
compartment” before working in the engine compartment.
For the sake of the environment
The oil level must on no account extend beyond the range
⇒page 227. Oil will
otherwise be drawn in through the crankc
ase ventilation and may pass through the
exhaust system to atmosphere. The oil ma
y combust in the cata
lytic converter and
damage it.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 225, “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 produc
t, 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 concentr
ation of antifreeze agent in the coolant
by adding water, also not during the summ
er 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 countries with a co
ld climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant wh
ich 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 co
olant (purple in colour), which complies
with the specification TL-VW 774 G. We recommend that you use the same c
oolant additive - G12 PLUS-PLUS (purple
in colour) for toppi
ng 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 al
so 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 bottle is loca
ted in the engine compartment on
the right. – Switch the engine off. – Open the bonnet
⇒
page 224.
– Check the level of coolant in the coolant expansion bottle
⇒
fig. 212
.
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 36, “Coolant temperat
ure/ Coolant quantity
”.
We nevertheless recommend in
specting 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 225, “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 229, fig. 212
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 228. 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 ad
justment 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 yo
ur 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 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 comp
liance with environmental protection
regulations.

Radiator fan The radiator fan may switch on suddenly.The radiator fan is driven by an electr
ic motor and controlled according to the
coolant temperature. The radiator fan may continue running fo
r 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 beca
use of an accumulation of heat or
•
the warm engine compartment is heated
up additionally by
strong sunlight.
WARNING
You must therefore be aware when work
ing in the engine compartment that
the fan may switch on suddenly - risk of injury!Brake fluidInspecting 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 compartment. – Switch the engine off. – Open the bonnet
⇒
page 224.
– Inspect the brake fluid level in the reservoir
⇒
fig. 213
. 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 br
ake 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. If the brake fluid level is too low, this is indicated by the warning light
⇒page 40, “Brake
system
” lighting up in the instru
ment cluster. In this case
stop immediately and
do not drive any further! Obtain professional assistance.
WARNING
•
Read and observe the warning notes
⇒page 225, “Working in the engine
compartment” before working in the engine compartment.•
If the fluid level has dropped below
the MIN marking, do not drive any
further - risk of accident! Obtain professional assistance.Replacing brake fluidBrake 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. Th
e 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 specification for
the brake fluid is “FMVSS 116 DOT 4”.
