Working in the engine compartment
Particular care is required when carrying out any work in the engine 
compartment!There is a risk of injuries, scalding, acci dents and fire when working in the engine 
compartment, e.g. inspecting and replenishing oil and other fluids. For this 
reason, it is essential to comply with the warning instructions stated below and 
with the general applicable rules of safe ty. The engine compartment of your car 
is a hazardous area   .
WARNING
Never open the bonnet if  you see that steam or coolant is flowing out of the 
engine compartment - risk of scalding!  Wait long enough until the steam or 
coolant has stopped escaping.
Switch off the engine and pull out the ignition key.
Apply the handbrake firmly.
If your vehicle is fitted with a manual  gearbox, move the gearshift lever into 
Neutral, or if it is fitted with automatic gearbox, move the selector lever into 
position P.
Allow the engine to cool down.
Keep children clear of the engine compartment.
Do not touch any hot engine parts - risk of burns!
Never spill oil and other fluids over the hot engine. Such fluids (e.g. the anti-
freeze contained in the wash liquid) may ignite!
Avoid short circuits in the electrical system - particularly on the battery.
Never place your hand into the radiator fan as long as the engine is still 
warm. The fan might suddenly start running!
Never open the cap of the coolant expans ion bottle as long as the engine is 
still warm. The cooling  system is pressurized!
Cover over the cap of the coolant expansion reservoir with a large cloth 
when opening it as protection for your  face, hands and arms from hot steam or 
hot coolant.
Do not let objects, such as e.g cleaning cloth or tools lie in the engine 
compartment.
If you wish to work under the vehicl e, you must secure the vehicle from 
rolling away and support it with suitable supporting blocks: the car jack is not 
sufficient for this - risk of injury!
In cases where it be necessary to carry out inspection work when the engine 
is running there is an additional risk fr om rotating parts (e.g. the V-ribbed belt, 
alternator, radiator fan) and from the high-voltage ignition system. Please 
observe in addition the following:
Never touch the electrical cabl es of the ignition system.
 Absolutely avoid any jewellery, loose it ems of clothing or long hair from 
getting into the rotating parts of the  engine - Hazard! Therefore remove any 
jewellery beforehand, tie up your hair and wear tight fitting clothing.
Please also comply with the warnin g instructions stated below when 
carrying out any essential work on the fuel system or on th e electrical system:
 Always separate the car battery from the electrical system.
 Do not smoke.
 Never carry out any work close to naked flames.
 Always keep a working fire  extinguisher at hand.Caution
When replenishing fluids in the engine, always  ensure that the fluids are on no account 
mixed up. This may result in major oper ating problems and also vehicle damage!

Caution
You must not pour any additives into the en gine 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 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 factory-
filled with coolant (purple in colour), which complies 
with the specification TL-VW 774 G.
We recommend that you use the antifr eeze agent G13 (purple in colour).
We recommend that you contact a specialist garage if you have any questions 
regarding the coolant or if you wish  to fill up with a different coolant.
A specialist garage can also supply  you with the correct coolant additives.
Coolant capacity
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.Petrol engines

Inspecting the coolant levelThe coolant expansion bottle  is located in the engine compartment on the right.
– Switch the engine off.
– Open the bonnet   in “Working in the engine compartment” on page 162.
– Check the level of coolant in the coolant expansion bottle  fig. 138 . The coolant 
level when the engine is cold must lie between the “MIN”   and “MAX”   mark-
ings. The level may also rise slightly above the “MAX” marking when the engine is 
warm.
If the coolant level in the reservoir is too lo w, this is indicated by the warning light in 
the instrument cluster 
   page 28. 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 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 162, “Working in the engine 
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as s oon 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. 138  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 165, “Coolant”. Do not use an al ternative additive if the coolant 
additive G12 PLUS - 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 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.Radiator fan
The radiator fan may switch on suddenly.The radiator fan is driven by an electric motor and controlled by a thermostat 
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 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   in “Working in the engine compartment” on page 162.
– Inspect the brake fluid level in the reservoir  fig. 139 . 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 
 lighting up in the 
instrument cluster  page 31. In this case  stop immediately and do not drive any 
further! Obtain professional assistance.
WARNING
Read and observe the warning notes  page 162, “Working in the engine 
compartment” before working  in the engine compartment.

– Release the fixtures in the openings   using a flat screwdriver and fold the cover 
upwards in direction of arrow  .
– Find out which fuse belongs to th e component which is not operating.
– Defect fuses can be detected by their melted metal strips. Replace the defect fuse  by a new fuse of the  same ampere number.
Caution
Never attempt to “repair” fuses and also do  not replace them with a fuse of a higher 
amperage - risk of fire! This  may also cause damage at an other part of the electrical 
system.
Have the electrical system checked as quickl y as possible by a specialist garage if a 
newly inserted fuse blows again after a short time.Note
We recommend that you have these fuses replaced by a specialist garage.Fuse assignment at the battery (manual gearbox, automatic gearbox DSG)Certain electrical components are only standard on certain vehicle model versions or
