Engine oilCheck engine oil level The dipstick indicates the le
vel of oil in the engine.
Checking the oil level– Ensure that the vehicle is po
sitioned on a level surface.
– Switch the engine off. – Open the bonnet
⇒
in “Working in the engine compartment” on page 204.
– Wait a few minutes and pull out the oil dipstick. – Wipe off the dipstick with a clea
n 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.

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 th
e 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 any maintenance under normal operating condi- tions. 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 mo
nths 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 prot
ection 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 factor
y-filled with coolant (purple
in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the same cool
ant additive - G12 PLUS-PLUS (purple in
colour) for topping up the system. Please contact an authorised Škoda Serv
ice 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 addi- tives.
Caution
•
Other coolant additives may cause operational problems which, in particular,
involves significantly reduci
ng the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequenc
e 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
⇒page 203.
– Check the level of coolant in the coolant expansion bottle
⇒fig. 173
. When the
engine is cold, the coolant level must
lie between the and markings. When
the engine is warm, the level may also lie slightly above the hatched part.
If the coolant level in the reservoir is too low, this is indicated by the warning light in the instrument cluster
⇒page 34, “Coolant temperature/ Coolant quantity
”. We

nevertheless recommend inspecting the cool
ant 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 204, “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
⇒page 207, fig. 173

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 th
e system, must comply with one specific
specification
⇒page 207. Do not use an alternative additive if the coolant additive
G12 PLUS - PLUS is not available in exceptio
nal 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 top up the fluid above the hatched pa
rt! 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 orig- inal 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 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.

Technical Data
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 igni
tion 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 workin
g in the engine compartment that the
fan may switch on suddenly - risk of injury!Brake fluidInspecting the brake fluid levelThe brake fluid reservoir is lo
cated 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 203.
– Inspect the brake fluid level in the reservoir
⇒fig. 174
. 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 brak
e 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 37, “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 204, “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. Exce
ssive 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 specification for the brake fluid is “FMVSS 116 DOT 4”. We recommend that you have th
e brake fluid re
placed by an
authorised Škoda
Service Partner
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 bubbl
es in the brake system. This greatly impairs the
braking efficiency an
d thus also the safety of your vehicle.
