– Allow the bonnet to drop from a height of about 30 cm into the
lock - bonnet do not press down on it!
The bonnet is held in the opened position by a pressurized gas spring.
WARNING
•Never open the bonnet if you see that steam or coolant is
flowing out of the engine compartmen t - risk of scalding! 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 properly after closing the bonnet.
•Stop your vehicle immediately while driving if you notice that
the lock is not properly engaged and close the bonnet properly -
risk of an accident!
Caution
•Never open the bonnet using the handle - danger of causing damage.
•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 en gine compartment
Particular care is required when carrying 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 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 safety. 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 gear-
shift 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 expansion 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.

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 215, fig. 162 and unscrew the cap carefully by
turning it to the left ⇒.
– Top up the coolant.
– Screw on 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 214, “Coolant”. Do not use an alterna-
tive additive if the coolant additive G12 PLUS is not available in excep-
tional cases. Just top up the system with water and as soon as possible
arrange adjustment to correct the mixing ratio of water and coolant addi-
tive again by a Škoda dealer.
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.
Do not continue your journey if for some reason it is not possible
under the conditions prevailing to top up with coolant. Switch off the
engine and obtain professional assistance from a Škoda dealer.
WARNING
•The cooling system is pressurized! Do not open the cap of the
coolant expansion bottle if the engi ne 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 your eyes, rinse out your eyes
immediately with clear water and contact a doctor as soon as
possible.
•You should also consult a doctor without delay if you have inad-
vertently swallowed coolant.
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.
The radiator fan
The radiator fan may switch on suddenly.
The radiator fan is driven by an electric motor and controlled by a thermo-
stat 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 ignition is also off. It may also
switch on suddenly after a certain time, if
•the coolant temperature has risen because of an accumulation of heat
or

The windshield washer reservoir contains the cleaning fluid for the wind-
screen and for the headlamp cleaning system*. The reservoir is located at
the front left of the engine compartment ⇒ page 223, fig. 168.
The reservoir has a capacity of 4 liters.
Clear water is not sufficient to intensively clean the windscreen and head-
lights. We therefore recommend using clean washing water together with
the screen cleaner from Škoda genuine accessories (in winter additionally
with antifreeze) which is capable of removing stubborn dirt. Follow the
instructions for use on the packaging when using screen cleaning prod-
ucts.
You should always add antifreeze to the cleaning water in winter even if
your vehicle is fitted with heated windscreen washer nozzles*.
It is also possible in exceptional cases to use methylated spirits when no
screen cleaner with antifreeze is available. The concentration of methyl-
ated spirits must not be more than 15 %. Please note, however, that the
antifreeze protection at this concentration is only adequate down to -5°C.
WARNING
Read and observe the warning notes ⇒page 209, “Working in the
engine compartment” before working in the engine compartment.
Caution
•On no account should you add radiator antifreeze or other additives to
the windscreen washer fluid.
•If the vehicle is fitted with headlight cleaning system, you should only
add cleaning products which do not attack the polycarbonate coating of
the headlights to the windscreen washer fluid. Please contact your Škoda
dealer, who will tell you which cleaning agent you can use.
Note
Do not take the filter out of the windscreen wash container when filling it
up again with liquid otherwise dirt can get into the liquid transportation
system and can lead to faults in operation of the windscreen wash
system.
