Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the bonnet support
into the holder 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 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 drivin g if you notice that the lock is not
properly engaged and close the bonnet properly - risk of an accident!
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.

On vehicles fitted with a manual gea rbox, move the gearshift lever into
Neutral.

Allow the engine to cool down.

Keep children clear of the engine compartment.

Never spill oil and other fluids over the hot engine. Such fluids (e.g. the anti-
freeze 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 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 lifting 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.

engines is practically identical.Engine oilEngine oil specificationsThe engine of your vehicle ha s been factory-filled with a high-grade oil which you can
use throughout the year - except in extreme climatic regions.
You can mix various oils together with each ot her when refilling with oil. This does not,
however, apply for models with flexible service intervals (QG1).
Engine oils are, of course, undergoing co ntinuous further development. Thus the
information stated in this Owner's Manual is only correct at the time of publication.
Authorised Škoda Service Partners are informed by Škoda Auto about current changes.
This why you should always have engine oi l changed by an authorised Škoda Service
Par tner.
The specifications (VW standards) stated in the following must be indicated separately
or together with other specifications on the bottle.

152For 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 material,
equipment and the knowledge required for such work, we recommend that you have
the oil and oil filter change carried out by a specialist garage.Note
After your skin has come in contact with th e oil, you must thoroughly wash your skin.Power steeringThe reservoir for hydraulic oil of power steering is located in the front right of the
engine compartment page 149, fig. 145 .
Check hydraulic oil
The hydraulic system of the power steering is filled with the hydraulic oil designated in
the catalogue as G 002 000.
Perform the inspection of the hydraulic oil level when the engine is cold and not
running.
The hydraulic oil level must be be tween the “MIN” and “MAX” markings fig. 147 . If
the level drops below the marking “MIN”, it is necessary that the power steering is
checked by a specialist garage. It is not su fficient to solely refill with hydraulic oil.
Note
If the engine is not running (when towing) or if the V-ribbed belt is torn, the power
steering does not operate. The vehicle is fully steerable however. There is however
increased force required to turn the steering wheel.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 prot ection 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 mont hs 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 protection 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 of fers 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 same coolan t additive - G13 (purple in colour) - for
topping up the system.
Please 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 yo u with the correct coolant additives.

Caution

Other coolant additives may cause operational problems which, in partic-
ular, involves significantly reducing the anticorrosion effect.

Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequence 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  in “Working in the engine compartment” on page 148.
– Check the level of coolant in the coolant expansion bottle fig. 148 . 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 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 148, “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. 148 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 152, “Coolant”. Do not use an al ternative additive if the coolant
additive G13 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 top up the fluid above the hatched pa rt! Excess coolant which is heated up is
forced out of the cooling system through th e 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.

154WARNING

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 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 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 working 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 148.
– Inspect the brake fluid level in the reservoir fig. 149 . 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 th e 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
