designed for it ⇒page 173, fig. 156.
Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the
bonnet support into the hold er designed to hold it.
– Allow the bonnet to drop from a height of about 30 cm into the lock -
bonnet do not press down on it!
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of the engine compartment - risk of scaldi ng! Wait long enough until the steam or coolant has stopped escaping.
•For safety reasons, the bonnet must always be properly closed when driving. One should therefore check that the lock has in fact engaged prop- erly after closing the bonnet.
•Stop your vehicle i mmediately while driving if you notice that the lock is not properly engaged and close the bonn et properly - risk of an accident!
Caution
•Before opening the bonnet, ensure that the arms of the windscreen wipers are correctly in place against the windscreen. Otherwise, there is a risk of damage to the paintwork.
Working in the engine compartment
Particular care is required when ca rrying out any work in the engine
compartment!
There is a risk of injuries, scalding, accidents and fire when working in the engine compartment, e.g. inspecting an d 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 safety. The engine compart-ment 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 scaldi ng! 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 antifreeze contained in the coolant) 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 expa nsion 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 from rotating parts (e.g. the V-

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 filled at the works with coolant (purple in colour), which complies with the specification TL-VW 774 F.
We recommend that you use the antifreeze agent - G12 PLUS (purple in colour).
We recommend that you contact your Škod a Service Partner if you have any ques- tions regarding the coolant or if you wish to fill up with a different coolant.
Your Škoda Service Partner can also suppl y 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 level
The 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 174.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 159.
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 24. 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 174, “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 179, fig. 159 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 178, “Coolant”. Do not use an alternative additive if the coolant additive G12 PLUS is not availa ble 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 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 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 comp liance 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 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 ha s 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 compartment 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 compartment.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 174.
– Inspect the brake fluid level in the reservoir ⇒fig. 160. 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. A situ-ation where the brake fluid level is too low is indicated by the warning light  lighting up in the instrument cluster ⇒page 28. In this case stop the car immedi- ately and do not drive any further! Cont act a Škoda Dealer to obtain profes- sional assistance.
WARNING
•Read and observe the warning notes ⇒page 174, “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! Contact a Škoda dealer to obtain professional assistance.
Replacing brake fluid
Brake 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.
