Wheels
First read and observe the introductory information and safety warn-
ings on page 97.
Wheel rims
Also thoroughly wash the wheel rims when washing the vehicle on a regular ba-
sis. Regularly remove salt and brake abrasion from the wheel rims otherwise the
material will be affected. Damage to the paint layer on the wheel rims must be
touched up immediately.
Light alloy wheels
After washing thoroughly and treat the wheel rims with a protective product for
light alloy wheels. Products which cause abrasion must not be used to treat the
wheel rims. WARNING
Water, ice and grit in the brake system can affect the braking efficiency – risk
of accident! CAUTION
Severe layers of dirt on the wheels can also result in wheel imbalance. This may
show itself in the form of a wheel vibration which is transmitted to the steering
wheel which, in certain circumstances, can cause premature wear of the steering.
This means it is necessary to remove the dirt. Note
We recommend that any repairs to damaged paintwork are carried out by a
ŠKODA Service Partner. ÐUnderbody protection
First read and observe the introductory information and safety warn-
ings on page 97.
The underside of your vehicle is protected for life against chemical and mechani-
cal influences.ä
ä As damage to the
protective layer when driving cannot be ruled out completely,
we recommend that you inspect the protective layer on the underside of your ve-
hicle and on the chassis at specific intervals – preferably at the beginning and end
of the winter.
ŠKODA Service Partners have suitable spray products and the necessary equip-
ment available, and are familiar with the instructions for use. We therefore rec-
ommend that touch-up work or additional corrosion protection measures are car-
ried out by a ŠKODA Service Partner. WARNING
Never use additional underbody protection or anti-corrosion agents for ex-
haust pipes, catalytic converters or heat shields. When the engine reaches its
operating temperature, these substances might ignite – risk of fire! Ð Protection of hollow spaces
First read and observe the introductory information and safety warn-
ings on page 97.
All the cavities of your vehicle which are at risk from corrosion are protected for
life by a layer of protective wax applied in the factory.
This wax protection does not require to be inspected or re-treated. If any small
amount of wax flow out of the cavities at high temperatures, these must be re-
moved with a plastic scraper and the stains cleaned using a petroleum cleaner. WARNING
Safety regulations should be observed when using petroleum cleaner to re-
move wax – risk of fire! Ð Artificial leather and materials
First read and observe the introductory information and safety warn-
ings on page 97.
The artificial leather can be cleaned using a damp cloth. If this does not prove to
be adequate, these parts can only be treated with special
solvent-free plastic
cleaning and care products . £

Taking care of and cleaning the vehicle

Unleaded petrol
First read and observe the introductory information and safety warn-
ings on page 104.
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 petrol 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

Inspecting and replenishing

The fuel tank is full when the compressor of the refuelling system automatically
switches off. To stop the refuelling operation prematurely, press the
“Stop ” but-
ton of the refuelling system.
Closing the filler cap
› Check that the sealing ring 3
» Fig. 96
has remained in the gas filler tube. If it
has slipped onto the filling coupling, reinsert it into the gas filler tube.
› Plug the cap 1
onto the gas filler tube.
› Close the filler cap.
In the following situation, it is possible that the tank cannot be fully filled with
natural gas.
› At very high ambient temperatures. The natural gas refuelling systems have
overheating protection. When the ambient temperature reaches a predefined
value, the refuelling system automatically switches off.
› If the refuelling system has been in operation for a longer period, the filling
pressure of the natural gas refuelling system slightly drops. WARNING
■ Stop the engine before refuelling.
■ Always switch off your mobile phone, do not smoke and do not use open
flames when refuelling with natural gas – risk of explosion!
■ When refuelling, never get into the vehicle. If you have to get into your vehi-
cle in exceptional cases, close the door and touch a metal surface before you
touch the filling coupling again. This will avoid electrostatic discharges, which
may generate sparks. Sparks can cause a fire during refuelling. ■ Natural gas is highly explosive and flammable. Incorrect refuelling or improp-
er handling of natural gas can cause a fire, an explosion and injuries. Note
■ The natural gas system of your vehicle is suitable both for fuelling from small
compressors (slow fuelling) and for fuelling from natural gas stations with large
compressors (quick fuelling). ■ Noises that occur during refuelling represent no risk.
■ If the vehicle is parked for a longer period of time immediately after refuelling,
the situation may arise in which the pointer of the fuel tank gauge does not indi-
cate exactly the same level as was the case immediately after refuelling when the
engine is restarted. This is not due to any system leakages but a drop in pressure
in the natural gas fuel tank due to technical reasons after a cooling phase directly
after refuelling. ■
For frequent short-haul traffic, especially at low outside temperatures, the vehi-
cle is driven more frequently in petrol mode than in natural gas mode. This is why
the petrol tank runs empty faster than the natural gas tank.
■ The capacity of the natural gas tank is about 11 kg, of which about 1.5
kg are a
reserve.
■ The capacity of the petrol tank is about 10 l, of which about 5 l
are a reserve.Ð Automatically switching over from CNG mode to petrol mode
First read and observe the introductory information and safety warn-
ings on page 106.
The vehicle automatically switches over from CNG mode to petrol mode when the
following conditions are met:
› when starting the engine, if the coolant temperature is below 15 °C,
› when the natural gas tank is empty,
› after refuelling with natural gas. Ð Natural gas as fuel
First read and observe the introductory information and safety warn-
ings on page 106.
Natural gas is an alternative fuel for motor vehicles. Its main component is meth-
ane (CH 4). The rest is carbon dioxide and lower hydrocarbons.
The strict legal requirements for exhaust emissions of motor vehicles are decisive
for the current significance of natural gas. In direct comparison to all other fossil
fuels, natural gas is one of the fuels which cause the lowest emissions.
Natural gas is odourless and lighter than air. For safety reasons, it is saturated
with odorous substances, so that is perceived even in very small amounts. Ð

Inspecting and replenishing

Regular inspections of gas systems
First read and observe the introductory information and safety warn-
ings on page 106.
Every two years, the following inspections must be carried out:
› Check solenoid valves on the gas tanks for proper function.
› Check natural gas tank and lines for leaks and fixing, if necessary look for dam-
ages.
› Check the condition of fuel filler cap, filler tube and sealing ring, clean sealing
ring if necessary. ÐSafe natural gas
First read and observe the introductory information and safety warn-
ings on page 106.
The safety concept of the natural gas system ensures safe operation. It is equip-
ped with the following security features.
› At each natural gas tank, there is a solenoid valve that closes automatically af-
ter turning off the ignition or when running in petrol mode.
› A thermal fuse prevents uncontrolled rise in pressure in the natural gas tank in
case of fire.
› A flow limiter prevents sudden emptying of the natural gas tank in case the
pressure system is damaged.
› All the attachment points and materials are designed for maximum safety. ÐNatural gas quality and consumption
First read and observe the introductory information and safety warn-
ings on page 106.
Natural gas is divided into quality groups H-gas and L-gas. The two types of gas
are subdivided according to their calorific value and nitrogen and carbon dioxide
contents. H-gas has a higher calorific value and lower nitrogen or carbon dioxide
content than L-gas.ä
ä
ä The higher the calorific value of natural gas, the lower is the consumption. How-
ever, the calorific value and the nitrogen and carbon dioxide contents can vary
within a quality group. Therefore, the consumption of the vehicle may even vary
when driving with only one natural gas quality (either only H-gas or L-gas).
The engine control of your vehicle automatically adjusts to the different natural
gas qualities. Therefore both natural gas qualities can be mixed in the fuel tank. It
is therefore not necessary to run the natural gas tank completely empty to fill up
another quality. Ð Engine compartment

reason, it is essential to comply with the warning instructions stated below and
with the general applicable rules of safety. The vehicle's engine compartment is
a hazardous area . £
108 General Maintenance

WARNING
■ Never open the bonnet if you can see steam or coolant flowing out of the
engine compartment – risk of scalding! Wait until the steam or coolant has
stopped escaping.
■ Turn off the engine and withdraw the ignition key.
■ If the vehicle is fitted with a manual gearbox, move the gearshift lever into
Neutral, or if the vehicle is fitted with an automatic gearbox, move the selec-
tor lever into position P .
■ Firmly apply the handbrake.
■ Allow the engine to cool.
■ For safety reasons, the bonnet must always be properly closed when driving.
This is why after closing the bonnet, the lock must always be checked to en-
sure it has engaged properly. ■ 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! WARNING (Continued)
■ 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! 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

Checking the engine oil level
Fig. 100
Dipstick
First read and observe the introductory information and safety warn-
ings on page 108.
The dipstick indicates the level of oil in the engine
» Fig. 100.
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 warning light in the instrument cluster will indicate whether the oil level is
too low » page 16 , Engine oil pressure. In this case, check the oil level with the
dipstick, as soon as possible. Add oil accordingly. CAUTION
■ The oil level must on no account extend beyond the range A
» Fig. 100. Risk of
damaging the exhaust system!
■ If it is not possible to top up the engine oil under the prevailing conditions,  do
not continue your journey! Switch off the engine and obtain professional assis-
tance from a ŠKODA specialist garage, otherwise it could cause severe engine
damage. Note
Engine oil specifications » page 146, Specifications and engine oil capacity .Ð Replenishing the engine oil
First read and observe the introductory information and safety warn-
ings on page 108.
›
Check the engine oil level
» page 111.
› 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 146, Specifications and engine oil capacity .
› Check the oil level

Inspecting and replenishing

Changing engine oil
First read and observe the introductory information and safety warn-
ings on page 108.
The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator
» page 10, Service Interval Display.CAUTION
Additives must not be added to the engine oil – risk of causing considerable dam-
age to parts of the engine! Damage, which results from such product, are exclu-
ded from the warranty. Note
If your skin has come into contact with oil, it must be washed thoroughly. ÐCoolant
First read and observe the introductory information and safety warn-
ings on page 108.
The cooling system is filled with a coolant in the factory.
The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture provides antifreeze protection down to -25
°C and 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.
The concentration of coolant must therefore not be reduced by adding water dur-
ing the summer months or in countries with a warm climate. The concentration of
coolant additive in the coolant must be at least 40 %.
If a higher concentration of antifreeze is required for climatic reasons, the amount
of coolant additive can only be increased 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 are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries the concentration of coolant additive should be at least 50 %.
When refilling, we only recommend you use the same antifreeze written on the
antifreeze expansion tank » Fig. 101 on page 112.

Petrol engines Capacities (in litres)
1.0 ltr./44 kW MPI 4.2
1.0 ltr./55 kW MPI 4.2
1.0 l/50 kW - CNG 4.2 CAUTION
■ Other coolant additives that do not comply with the correct specifications can
above all significantly reduce the anticorrosion effect.
■ Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage! Ð Checking the coolant level
Fig. 101
Engine compartment: Coolant
expansion reservoir
First read and observe the introductory information and safety warn-
ings on page 108.
The coolant expansion bottle is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 110.
› Check the level of coolant in the coolant expansion bottle
» Fig. 101. The cool-
ant level when the engine is cold must lie between the
“MIN” and “MAX” mark-
ings. The level may also rise slightly above the “MAX” marking when the engine
is warm.
If the coolant level in the coolant expansion tank is too low, this is indicated by
the warning light  lighting up in the instrument cluster » page 16, Coolant tem-
perature/coolant level . We still recommend inspecting the coolant level directly
at the reservoir from time to time. £
