Working in the engine compartment Particular care is required when carrying out any work in the en-
gine compartment!
There is a risk of injuries, scalding, accidents and fire when working in the en-
gine 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 gearshift lever in-
to Neutral, or if it is fitted with automatic gearbox, move the selector lever in-
to 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 an-
tifreeze 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 reservoir so long as the en-
gine is still warm. The cooling system is pressurized!
● Cover over the cap of the 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 com-
partment.
● If you wish to work under the vehicle, 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! WARNING (Continued)
● In cases where it be necessary to carry out inspection work when the en-
gine is running there is an additional risk from 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 cables of the ignition system.
– Absolutely avoid any jewellery, loose items 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 warning instructions stated below when car-
rying out any essential work on the fuel system or on the 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 ac-
count mixed up. This may result in major operating problems and also vehicle
damage! 

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 dam-
age 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. 125 and un-
screw 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 153, Coolant. Do not use an alternative additive if the
specified coolant additive is not available in exceptional cases. Just top up the sys-
tem 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 cool-
ant 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 dam-
age. WARNING
● The cooling system is pressurized! Do not open the cap of the coolant ex-
pansion 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! WARNING (Continued)
● If any splashes of coolant get into your 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 condi-
tions prevailing to top up with coolant. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe en-
gine 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 regula-
tions. 
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 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 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! 155

CAUTION
Vehicles with a “START-STOP” system are fitted with a special battery type which
allows the battery control unit to check the energy level for recurring engine start.
This battery must only be replaced by a battery of the same type. For the sake of the environment
Batteries contain poisonous substances such as sulphuric acid and lead. For this
reason, it must be disposed of properly. Under no circumstances must it be dis-
posed of in the communal rubbish. 
Automatic consumer shut-off Under heavy load on the vehicle battery, the vehicle electrical system manage-
ment automatically takes various measures to avoid draining the vehicle battery.
●
The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
● If necessary, some electrical consumers are limited in their performance or are
temporarily switched off completely. Note
Despite such intervention by the vehicle electric system management, the vehicle
battery may be drained. For example, when the ignition is switched on a long time
with the engine turned off or the side or parking lights are turned on during lon-
ger parking. 
Windshield washer system Fig. 129 Engine compartment: Wind-
shield washer fluid reservoir The windshield washer fluid reservoir contains the cleaning fluid for the wind-
shield or rear window and for the headlamp cleaning system. The reservoir is loca-
ted in the front of the engine compartment on the right side of the vehicle
⇒ fig. 129
. On some vehicles, the reservoir is located on the left side of the vehicle
next to the battery.
The filling level of the container is about 3.5 litres and about 5.4 litres on vehicles
which have a headlight washing system.
Clear water is not sufficient to intensively clean the windshield and headlights.
We therefore recommend using clean washing water together with the screen
cleaner from
ŠKODA Original 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 products.
You should always add antifreeze to the cleaning water in winter even if your ve-
hicle is fitted with heated windshield washer nozzles.
It is also possible in exceptional cases to use methylated spirits when no screen
cleaner with antifreeze is available. The concentration of methylated 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 150
, Working in the engine com-
partment before working in the engine compartment. CAUTION
● On no account should you add radiator antifreeze or other additives to the
windshield washer fluid.
● If the vehicle is fitted with a headlight cleaning system, you should only add
cleaning products which do not attack the polycarbonate glass of the headlights
to the windshield washer fluid. Please contact an authorised

ŠKODA Service Part-
ner who will help you select a suitable cleaning agent. Note
Do not take the filter out of the windshield 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 windshield wash system. 160
