The engine has been filled ex-factory with a high-grade oil that can be used
throughout the year (except in extreme climate zones).
We recommend that the oil changes be carried out by a ŠKODA Service Part-
ner.
The engine oil should be changed at specified service intervals » page 242.
The engine uses up some oil, depending on driving style and operating condi-
tions (up to 0.5 l / 1 000 km). Consumption may be slightly higher than this dur-
ing the first 5 000 km.
WARNINGThe following instructions must be followed at all times when working on

Coolant
 Introduction
This chapter contains information on the following subjects:
Checking and refilling
257
The coolant helps to keep the engine temperature down, and consists of wa-
ter and coolant additive (with additives that protect the cooling system against
corrosion and prevent furring).
The proportion of coolant additive in the coolant must be 40 to 60 %.
The correct mix of water and coolant additive should be checked and if neces-
sary corrected by a specialist garage.
WARNING■ The following instructions must be followed at all times when working on
the engine compartment » page 252.■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurised - risk of scalding or
injury from splashes of coolant!
■
To protect against the coolant splashing, cover the cap with a cloth when
opening.
■
Coolant and coolant fumes are harmful - avoid contact with the coolant. If
the coolant comes into contact with the eye or skin, wash the affected area
with plenty of water for several minutes, and where appropriate seek medi-
cal help.
CAUTION
Do not cover the radiator and install any parts (e.g auxiliary lights.) in front of
the air intakes - There is a risk of the engine overheating.256General Maintenance

Checking and refillingFig. 294
Coolant expansion reservoir
Read and observe and on page 256 first.
Check and refill coolant under the following conditions.The vehicle is on a horizontal surface.
The engine is not warm (if the engine is warm the result of the check may
be wrong).
The engine is turned off.
Check the coolant level - The coolant level must lie between the marks
A
and
B
» Fig. 294. If the coolant level is below the mark
B
, top up with coolant.
Refilling
The reservoir must always contain a small amount of coolant »
.
›
Place a cloth over the cap of the coolant expansion reservoir and unscrew
the cap carefully .
›
Always top up using coolant of the correct specification.
›
Turn the cap until it clicks into place.
The specification for the coolant is shown in the coolant expansion reservoir
» Fig. 294 .
If the specified coolant is not available, then refilling only with distilled or puri-
fied water, and get a specialist garage to correct the water-coolant additive
mix as soon as possible.
CAUTION■ If the expansion tank is empty, do not top up with coolant. The system could
aerate - There is a risk of engine damage!  Stop driving! Switch off the en-
gine and seek assistance from a specialist garage.■
Do not fill the coolant above the mark
A
» Fig. 294 . The coolant could, when
heated, be expelled from the cooling system - There is a risk of damage to the
engine parts.
■
If it is not possible to add coolant, 
stop driving! Switch off the engine and
seek assistance from a specialist garage.
■
A coolant additive which does not correspond to the correct specification can
reduce the anti-corrosion effect of the cooling system - risk of damage to the
cooling system and the engine.
■
If distilled (purified) water has been used to top up, the coolant should be re-
placed by a specialist garage - risk of engine damage.
■
A loss of coolant indicates leaks in the cooling system - risk of engine dam-
age. Top up with coolant and then seek assistance from a specialist garage.
Note
A coolant level which is too low is indicated in the instrument cluster by the
warning light and shown by the relevant message » page 38. We still recom-
mend inspecting the coolant level directly at the reservoir from time to time.

Disconnect/reconnect and change
260
The vehicle battery represents a power source for the motor to start and for the supply of electrical consumers in the car.
Automatic consumer shutdown - Discharge protection of the vehicle battery
The on-board power supply system tries to prevent the vehicle battery from
discharging in the following ways when it is subject to heavy loading. ▶ By increasing the engine idle speed.
▶ Through the power limitation of certain loads.
▶ By switching off some loads(heated seats, heated rear window) for as long
as necessary.
Warning symbols on the vehicle batterySymbolMeaningAlways wear eye protection!Battery acid is severely caustic. Always wear gloves and eye pro-
tection!Keep fire, sparks, open flames and lit cigarettes well clear of the
vehicle battery!When charging the vehicle battery, a highly explosive gas mixture
is produced!Keep children away from the vehicle battery!WARNINGBattery acid is highly corrosive - it can cause injury, chemical burns or poi-
soning! Corrosive vapours in the air irritate and damage the respiratory
tract and the eyes. The following guidelines must be observed.■
Always wear protective gloves, eye and skin protection when handling
the vehicle battery.
■
If your eyes or skin come into contact with the electrolytic fluid, immedi-
ately wash the affected area for a few minutes long with a lot of water. Get
medical assistance without delay.
■
Keep the vehicle battery away from people who are not completely inde-
pendent (e.g. children).
■
Do not tilt the battery otherwise battery electrolyte may flow out of the
battery vent openings.
WARNINGWorking on the car battery may cause explosion, fire, injury or chemical
burn! The following guidelines must be observed.■
Do not smoke, use open flames or light or transmitting devices.
■
A discharged vehicle battery may freeze slightly. Never charge up a fro-
zen or thawed vehicle battery. Replace a frozen vehicle battery.
■
Never use a damaged vehicle battery.
■
Do not connect the battery terminals, bridging the two poles will cause a
short circuit. 
258General Maintenance

CAUTIONEnsure that battery acid does not come into contact with the bodywork –
There is a risk of damage to the vehicle.
Note
■ We recommend having all work on the vehicle battery carried out by a spe-
cialist garage.■
You should replace batteries older than 5 years.
Check condition
Fig. 296
Vehicle battery: Open the cover / acid level indicator
Read and observe
and on page 258 first.
The battery condition is checked regularly by a specialist garage as part of the
inspection service.
Check the acid level
For car batteries with acid level indicator, acidity can be checked on the basis
of a colour display. In vehicle batteries with the label “AGM” there is no acid
level examination.
Depending on the equipment, the vehicle battery may be provided with a cov-
er, this can be opened in the direction of arrow » Fig. 296 -
 .
Air bubbles can influence the colour of the indicator. For this reason carefully
tap on the indicator before carrying out the check » Fig. 296 -
 .
Black colour – electrolyte level is correct.
Colourless or light yellow colour – electrolyte level too low, the battery must be replaced.
Battery discharge
If frequent short journeys are made, the vehicle battery does not recharge suf- ficiently.
The battery capacity decreases at low temperatures.
If the vehicle is not used for longer than 3 to 4 weeks, then disconnect the
negative terminal 
of the battery or charge the battery constantly with a very
low charging current.
Charging
Read and observe
and on page 258 first.
Only charge the battery when the ignition and all consumers are switched off.
Refer to the instructions of the charger manufacturer.

mains cable from the power socket.
›
Disconnect the terminals of the charger from the vehicle battery.
A charging current of 0.1 multiple of the total vehicle battery capacity (or low-
er) must be used until full charging is achieved.
WARNING■ When charging the vehicle battery, hydrogen is released - risk of explo-
sion. An explosion can be caused through sparking while unclamping or
loosening the cable plug.■
So-called “quick-charging” of the vehicle battery is dangerous and re-
quires a special charger and specialist knowledge. Therefore, have“Quick
loading” carried out by a specialist garage.

We recommend having bulbs replaced by a specialist garage or seeking other
expert help in the event of any uncertainties.
▶ Switch off the ignition and all of the lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
We recommend having the headlight settings checked by a specialist garage after replacing a bulb in the low, high or fog beam.
In the case of failure of a Xenon gas discharge bulb or an LED diode, visit a
specialist garage.WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 252.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
■
Bulbs H7 H8 and H15 are pressurised and may burst when changing the
bulb - risk of injury! We therefore recommended wearing gloves and safety
glasses when changing a bulb.
■
Do not carry out any work on the Xenon gas discharge lamps - risk of
death!
CAUTION
Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
napkin, or similar.
Note
■ This Owner's Manual only describes the replacement of bulbs where it is pos-
sible to replace the bulbs on your own without any complications arising. Other
bulbs must be replaced by a specialist garage.■
We recommend that a box of replacement bulbs always be carried in the ve-
hicle.
