Unleaded petrol
First read and observe the introductory information and safety warn-
ings on page 167.
Your vehicle can only be operated with
unleaded fuel that complies with the
standard EN 228 (in Germany: standard DIN 51626-1 or E10 for unleaded fuel with
an octane rating of 95 RON and 91 RON or DIN 51626-2 or E5 for unleaded fuel
with the octane rating 95 RON and 98 RON).
Prescribed fuel - unleaded fuel 95/91 RON
Use unleaded fuel with the octane rating 95 RON. Unleaded petrol 91 RON can al-
so be used but results in a slight loss in performance.
If, in an emergency, the vehicle has to be refuelled with petrol of a lower octane
number than the one prescribed, the journey must only be continued at medium
engine speeds and a low engine load. Driving at high engine revs or a high engine
load can severely damage the engine! Refuel using petrol of the prescribed oc-
tane number as soon as possible.
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded fuel with the octane rating 95 RON.
In case of necessity, you can refuel with petrol with the octane rating 91 RON if
petrol with the octane rating 95 RON is not available. The journey must only be
continued at medium engine speeds and a minimum engine load. Driving at high
engine revs or a high engine load can severely damage the engine! Refuel using
petrol of the prescribed octane number as soon as possible.
Even in the event of an emergency, petrol of a lower octane number than 91 RON
must not be used, otherwise the engine can be severely damaged!
Unleaded petrol with higher octane number
Unleaded petrol that has a higher octane number than that required by the en-
gine can be used without limitations.
On vehicles with prescribed unleaded petrol 95/91 RON, the use of petrol with a
higher octane number than 95 RON does not result in a noticeable power in-
crease or a lower fuel consumption.
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of petrol
with a higher octane number than 95 RON can increase the power and reduce
fuel consumption. ä
Prescribed fuel - unleaded fuel 98/95 RON
Use unleaded fuel with the octane rating 98 RON. Unleaded petrol 95 RON can
also be used but results in a slight loss in performance.
In case of necessity, you can refuel with petrol with the octane rating 91 RON of
unleaded fuel with octane rating 98 RON or 95 RON is not available. The journey
must only be continued at medium engine speeds and a minimum engine load.
Driving at high engine revs or a high engine load can severely damage the engine!
Refuel using petrol of the prescribed octane number as soon as possible.
Even in the event of an emergency, petrol of a lower octane number than 91 RON
must not be used, otherwise the engine can be severely damaged!
Fuel additives
Only use unleaded petrol, which complies with the standard EN

228 (in Germany:
standard DIN 51626-1 or E10 for unleaded fuel with an octane rating of 95 RON
and 91 RON or DIN 51626-2 or E5 for unleaded fuel with an octane rating of
95 RON and 98 RON), as these meet all of the requirements for fault-free engine
operation. We therefore recommend that no fuel additives are used. CAUTION
■ All
ŠKODA vehicles with petrol engines must only be operated with unleaded
petrol. Just filling the tank with leaded petrol once will damage the exhaust sys-
tem!
■ Engine parts can be damaged if petrol with a lower octane number than the one
prescribed is used.
■ In no case may fuel additives with metal components be used, especially not
with manganese and iron content.
LRP (lead replacement petrol) fuels with met-
allic components may not be used. There is a risk of causing considerable damage
to parts of the engine or exhaust system!
■ Fuels with metallic content may not be used. There is a risk of causing consider-
able damage to parts of the engine or exhaust system!
■ The use of unsuitable fuel additives can cause considerable damage to parts of
the engine or the exhaust system. Ð
168 General Maintenance

WARNING (Continued)
■ If you notice that the lock is not properly engaged while driving, stop the ve-
hicle immediately and close the bonnet - risk of an accident!
■ Keep children clear of the engine compartment.
■ Do not touch any hot engine parts - risk of burns!
■ Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite!
■ Avoid short circuits in the electrical system - particularly on the vehicle's
battery.
■ Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running! ■ Never open the end cover of the coolant expansion reservoir while the en-
gine is still warm. The cooling system is pressurized!
■ When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot cool-
ant.
■ Do not leave any items such as cloths or tools in the engine compartment.
■ If you wish to work under the vehicle, you must secure the vehicle from roll-
ing away and support it with suitable supporting blocks: the car jack is not
sufficient for this - risk of injury!
■ If any inspection work has to be carried out when the engine is running,
there is an additional risk from rotating parts (e.g. V-belt, alternator, radiator
fan) and the high-voltage ignition system. The following must also be ob-
served. ■Never touch the electric wiring on the ignition system.
■ Always make sure that no jewellery, loose clothing or long hair can get
caught in rotating engine parts - hazard! Always remove any jewellery, tie
back long hair and wear tight fitting clothing before completing any work.
■ Additionally, the following warning instructions must be observed if work
has to be carried out on the fuel or electrical system. ■Always disconnect the vehicle battery from the electrical system.
■ Do not smoke.
■ Never work near open flames.
■ Always have a functioning fire extinguisher nearby. CAUTION
■ Always top up using the correct specification of fluids. This may result in major
operating problems and also vehicle damage!
■ Never open the bonnet using the locking lever - danger of causing damage. For the sake of the environment
In view of the environmentally friendly disposal of fluids, the specials tools and
knowledge required for such work, we recommend that fluids are changed by a
Škoda
Service Partner as part of the inspection service. Note
■ If you have any questions regarding the fluids, visit a
ŠKODA Service Partner.
■ Fluids with the correct specifications can be purchased from ŠKODA Original Ac-
cessories. Ð
170 General Maintenance

Checking the engine oil level
Fig. 142
Dipstick
First read and observe the introductory information and safety warn-
ings on page 169.
The dipstick indicates the level of oil in the engine
» Fig. 142.
Checking the oil level
› Ensure that the vehicle is positioned on a level surface and the engine has
reached its operating temperature.
› Switch off the engine.
› Open the bonnet.
› Wait a few minutes until the engine oil flows back into the oil sump and remove
the dipstick.
› Wipe the dipstick with a clean cloth and insert it again to the stop.
› Then pull the dipstick out again and check the oil level.
Oil level within range A
›
No oil must be refilled.
Oil level within range B
›
Oil can
be refilled. It is possible that the oil level may then be within range A
after doing this.
Oil level within range C
›
Oil must be refilled. It is sufficient, once this is done, to keep the oil level within
range B
.
It is normal for the engine to consume oil. The oil consumption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. Consumption may be slightly higher than this during the
first 5 000 kilometres. ä
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range A
, but not above
, if
the engine has been operating at high loads, for example, during a lengthy motor-
way trip during the summer months, towing a trailer or negotiating a high moun-
tain pass.
The indicator light in the instrument cluster will indicate whether the oil level is
too low » page 21, Engine oil  . In this case, check the oil level with the dip-
stick, as soon as possible. Add oil accordingly. CAUTION
■ The oil level must on no account extend beyond the range A
» Fig. 142. Risk of
damaging the exhaust system!
■  Do not continue your journey if for some reason it is not possible to top up
the engine oil under the prevailing conditions! Switch off the engine and obtain
professional assistance from a

ŠKODA specialist garage, otherwise it could cause
severe engine damage. Note
Engine oil specifications » page 210, Specifications and engine oil capacity .Ð Replenishing the engine oil
First read and observe the introductory information and safety warn-
ings on page 169.
›
Check the engine oil level
» page 172.
› Unscrew the cap of the engine oil filler opening.
› Replenish the oil in portions of 0.5 litres in accordance with the correct specifi-
cations » page 210, Specifications and engine oil capacity .
› Check the oil level
» page 172.
› Carefully screw on the oil filler opening cap and push the dipstick in fully. Ð

172 General Maintenance

Checking the coolant level
Fig. 143
Engine compartment: Coolant
expansion reservoir
First read and observe the introductory information and safety warn-
ings on page 169.
The coolant expansion bottle is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 171.
› Check the level of coolant in the coolant expansion bottle
» Fig. 143. The cool-
ant level when the engine is cold must lie between the B
(MIN) and A
(MAX)
markings. The level may also rise slightly above the A
(MAX) marking when the
engine is warm.
If the coolant level in the coolant expansion tank is too low, this is indicated by
the indicator light  lighting up in the instrument cluster » page 20, Coolant tem-
perature/coolant level . We still 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. Do
not merely top up the coolant. Have the cooling system checked by a
ŠKODA spe-
cialist garage immediately. CAUTION
If a fault causes the engine to overheat, we recommend visiting a ŠKODA Service
Partner immediately, otherwise serious engine damage may occur. Ð
ä Replenishing the coolant
First read and observe the introductory information and safety warn-
ings on page 169.
›
Switch off the engine.
› Allow the engine to cool.
› Place a cloth over the cap of the coolant expansion reservoir
» Fig. 143 on
page 174 and unscrew the cap carefully.
› Replenish the coolant.
› Turn the cap until it clicks into place.
Do not use an alternative additive if the specified coolant is not available in an
emergency. In this case, just use water and have the correct mixing ratio of water
and the coolant additive restored by a ŠKODA

specialist garage as soon as possi-
ble.
Only use new coolant to top up the system.
Do not fill the coolant above the mark A
(max.)
» Fig. 143 on page 174! Excess
coolant heats up and then is forced out of the cooling system through the pres-
sure relief valve in the cap. WARNING
■ 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 health.
Therefore always safely store the coolant additive in its original container out
of the reach of children - risk of poisoning!
■ If any coolant splashes into your eyes, immediately rinse out your eyes 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 it is not possible  to top up the coolant under
the prevailing conditions . Contact a

ŠKODA Service Partner to avoid the risk of
serious engine. Ð

174 General Maintenance

Windscreen washer system
Fig. 145
Engine compartment: Wind-
screen washer fluid reservoir
First read and observe the introductory information and safety warn-
ings on page 169.
The windscreen washer fluid reservoir contains the cleaning fluid for the wind-
screen or rear window and for the headlight cleaning system. The windscreen
washer fluid reservoir is located in the engine compartment.
The filling level of the container is about 3
litres and about 5.5 litres on vehicles
that have a headlight washing system 1)
.
Clear water is not sufficient to intensively clean the windscreen and headlights.
We therefore recommend using clean water with a screen cleaner (including anti-
freeze in the winter) that is able to remove stubborn dirt.
Antifreeze should always be added to the cleaning water in the winter even if the
vehicle is fitted with heated windscreen washer nozzles.
Under exceptional circumstances, methylated spirits can also be used if no screen
cleaner with antifreeze is available. The concentration of methylated spirits must
not be more than 15 %. The freeze protection at this concentration is sufficient
only to -5 °C. CAUTION
■ Under no circumstances must radiator antifreeze or other additives be added to
the windscreen washer fluid.
■ If the vehicle is fitted with a headlight cleaning system, only cleaning products
which do not attack the polycarbonate coating of the headlights must be added
to the windscreen washer fluid.
ä Note
Do not remove the filter from the windscreen washer fluid reservoir when replen-
ishing it with liquid otherwise the liquid transportation system can be contamina-
ted, which can cause the windscreen washer system to malfunction. Ð Vehicle battery

176 General Maintenance

Battery cover
Fig. 146
Engine compartment: Polyester cover of the vehicle battery/plastic
cover of the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 176.
The battery is located in the engine compartment in a polyester cover
1
» Fig. 146 or in a plastic cover 2
» Fig. 146.
› Open the battery cover in the direction of the arrow 1
or press the interlock on
the side of the battery cover in the direction of the arrow 2
» Fig. 146
, fold the
cover up and remove.
› The battery cover is installed in reverse order.
When working on the battery, the edge of the polyester battery cover 1
» Fig. 146 is inserted between the battery and the side wall of the battery cov-
er. ÐChecking the battery electrolyte level
Fig. 147
Vehicle battery: Electrolyte level
indicator
ä
First read and observe the introductory information and safety warn-
ings on page 176.
We recommend you have the electrolyte level checked by a ŠKODA specialist ga-
rage from time to time, especially in the following cases.
› High outside temperatures.
› Long daily drives
› After each charge
» page 179.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 147, the electrolyte level can be determined by looking at the
change in colour.
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check. › Black colour - electrolyte level is correct.
› Colourless or light yellow colour - electrolyte level too low, the battery must be
replaced. Note
■ The battery electrolyte level is periodically checked by a ŠKODA Service Partner
as part of the Inspection Service. ■ For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked. ■ Vehicles with a START-STOP system are fitted with a battery control unit for
checking the energy level for the recurring engine start. Ð Operation in winter
First read and observe the introductory information and safety warn-
ings on page 176.
At low temperatures, the vehicle battery only has part of the initial power output
that it has at normal temperatures.
A discharged vehicle battery may already freeze at temperatures just below 0
°C.
We therefore recommend that you have the battery checked and, if necessary, re-
charged by a ŠKODA Service Partner before the start of the winter. Ð

178 General Maintenance

Automatic load deactivation
First read and observe the introductory information and safety warn-
ings on page 176.
An intelligent vehicle power management system automatically takes various
measures at high loads on the vehicle battery to prevent discharging of the bat-
tery: This manifests itself by the following:
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where appropriate large consumers of power, e.g. seat heaters, rear window
heaters, voltage supply to the 12V power socket, have their power limited or in
case of emergency shut 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. Driving comfort is not put at risk by any shutting off of consumers.
Often the driver is not aware of it having taken place. Ðä
180 General Maintenance

Note
■ We recommend that any work on the wheels or tyres is carried out by a ŠKODA
Service Partner. ■ We recommend that you use wheel rims, tyres, full wheel trims and snow chains
from
ŠKODA Original Accessories. ÐService life of tyres
Fig. 148
Tyre tread with wear indicators/Open fuel filler flap with a table
detailing the tyre size and tyre inflation pressure
First read and observe the introductory information and safety warn-
ings on page 181.
Wear indicators
The base of the tread of the tyres has 1.6 mm high wear indicators installed.
These wear indicators are located multiple times depending on the make and are
evenly spaced around the circumference of the tyre » Fig. 148 - . Markings on
the walls of the tyres through the letters

“TWI”, triangular symbols or other sym-
bols identify the position of the wear indicators.
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insuffi-
ciently or over-inflated and this will have an adverse effect on the handling of
your vehicle. Therefore check the tyre pressure, including that of the spare wheel,
at least once a month and also before setting off on a long journey.
ä The tyre inflation pressures for
summer tyres are indicated on the inside of the
fuel filler flap » Fig. 148 - . The inflation pressures for winter tyres are 20

kPa
(0.2 bar) higher than those for summer tyres.
The tyre inflation pressure for tyres of the tyre size 205/50 R17 or 205/55 R16,
which are intended to be used with snow chains, is identical to the tyre inflation
pressure for tyres of the tyre size 225/45 R17 or 215/60 R16.
Always check the inflation pressure when the tyres are cold. Do not reduce the
higher pressure of warm tyres. If the load varies greatly, adjust the tyre inflation
pressure accordingly.
Driving style
Fast cornering, sharp acceleration and braking increase the wear of your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences
when driving which may result in an imbalance and which makes themselves felt
through vibration in the steering.
Have the wheels rebalanced after replacing the tyres.
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-and-
tear on the tyres but will also has an adverse effect on vehicle safety. In the
event of any unusual tyre wear, seek assistance from a ŠKODA specialist garage.
Tyre damage
Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angle in order to avoid damage to tyres and wheel
trims.
We recommend checking your tyres and wheel rims for damage (punctures, cuts,
splits and bulges, etc.) on a regular basis. Remove foreign bodies from the tyre
profile.
Unusual vibrations or pulling of the vehicle to one side could be a sign of tyre
damage. If there is any doubt that a wheel is damaged, immediately reduce your
speed and stop! Check the tyres for signs of damage (bulges, splits, etc.). If no ex-
ternal damage is evident, drive slowly and carefully to the nearest ŠKODA special-
ist garage to have the vehicle checked. Ð
