126WARNING■When operating a CNG-powered vehicle, the national legal requirements
must be observed.■
If a fault occurs or a leak in the natural gas system is suspected or if you
smell gas, proceed as follows: ■Stop immediately and switch off the ignition (this will close the solenoid
valves on the natural gas tanks automatically);
■ Open the doors to ventilate the vehicle sufficiently;
■ Immediately extinguish cigarettes, and remove and switch off other spark-
or fire-causing objects from the vehicle immediately. ■ Seek help from a specialist garage to correct the gas system fault.
■
The following are considered faults on the gas system:
■ Gas leakage from any part of the gas system as well as an error on the
ventilation system.
■ Continuous gas venting through the safety valves.
■ Cracks or damage that could result in a gas leak.
■ Fault in the reduction device, the pressure regulator, gas mixer or in the
injection valves, the pressure gauge, the shut-off or check valves and tank
fixtures.
■ If gas flows into the gas mixer or into the injection valves though the en-
gine is stopped.
■ Exceeding the permissible limits for contaminants in the exhaust gas.
■
Regular gas system checks must be carried out in order to operate a natural
gas vehicle. The vehicle owner is responsible for properly conducted tests.
■
The natural gas tanks must not be exposed to a heat source.
■
Always switch off the ignition in case of an accident or vehicle fire!
■
It is prohibited to drive into automatic car washes, enclosed storage places,
garages and similar areas where it is specifically forbidden to enter with CNG vehicles.
RefuellingFig. 100
Fuel filler
First read and observe the introductory information and safety warn-ings on page 123.
The gas filler tube for refuelling with natural gas is located behind the fuel filler
flap next to the petrol filler tube.
The filling couplings of the natural gas refuelling systems may differ in handling.
When refuelling with natural gas at unfamiliar refuelling systems, you should
seek help from trained fuel station staff. If unsure, have the refuelling done by
trained fuel station staff.
The operating instructions of the refuelling system must always be followed.

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 theengine is restarted. This is not due to any system leakages but a drop in pressurein 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.
Automatic switching from CNG to petrol mode
First read and observe the introductory information and safety warn-
ings
on page 123.
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.
Natural gas as fuel
First read and observe the introductory information and safety warn-ings
on page 123.
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.
Regular gas system checks
First read and observe the introductory information and safety warn-ings
on page 123.
Every two years, the following inspections must be carried out:
› Check the condition of the fuel filler cap, filler neck and sealing ring, and clean
sealing ring if necessary.
› Check gas system for leaks.
The following checks must be carried out every four years: › Check gas tank mounting for secure attachment and possible damage.
The gas tank must be filled prior to the regular gas system check.

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.■
Do not remove the filter from the windscreen washer fluid reservoir when refill-
ing, as this may cause contamination of the liquid transportation system, leading
in turn to a windscreen washer system malfunction.

The engine has been factory-filled with a high-grade oil that can be use through-
out the year - except in extreme climate zones.
The engine oils are undergoing continuous further development. Thus the infor-
mation stated in this Owner's Manual is only correct at the time of publication.
ŠKODA Service Partners are informed about the latest changes by the manufac-
turer. We therefore recommend that the oil change be completed by a ŠKODA
Service Partner.
The specifications (VW standards) stated in the following can be indicated sepa-
rately or together with other specifications on the bottle.
The oil capacities include oil filter change. Check the oil level when filling; do not
over fill. The oil level must be between the markings » page 131.
WARNING■
The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 127.■
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
seek assistance from a specialist garage.
■
If the oil level is above level
A
» Fig. 107 on page 131, do not continue to
drive! Switch off the engine and seek assistance from a specialist garage.
CAUTION
Do not pour any additives into the engine oil – risk of serious damage to the en-
gine parts!
Note
■ Before a long drive we recommend that you purchase and carry with you engine
oil which complies with the specification for your vehicle.■
We recommend that you use oils from ŠKODA Original Accessories.
■
If your skin has come into contact with oil, it must be washed thoroughly.

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.
Vehicles with a START-STOP system are fitted with a battery control unit for checking the energy level for the recurring engine start.
We recommend that you have the acid level checked regularly by a specialist ga-
rage, especially in the following cases.
› High external temperatures.
› Longer day trips.
› After each charge.
CAUTION
For technical reasons, on vehicles with the description “AGM”, the electrolyte lev-
el cannot be checked.
Note
The battery acid level is also checked regularly by a specialist garage as part of
the inspection service.
Operation in winter
First read and observe the introductory information and safety warn-
ings
on page 134.
The vehicle battery only has a proportion of the starting power in lower tempera-
tures. A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C .
We therefore recommend that you have the battery checked and, if necessary, re-
charged by a specialist garage before the start of the winter.
Charging
First read and observe the introductory information and safety warn-ings
on page 134.
A properly charged vehicle battery is essential for reliably starting the engine.
› Switch off the ignition and all of the electrical components.›Only when performing a “quick-charge”, disconnect both battery cables (first
“negative”, then “positive”).›
Attach the terminal clamps of the charger to the battery terminals (red = “posi- tive”, black = “negative”).
›
Plug the mains cable of the charger into the power socket and switch on thedevice.
›
After charging has been successful: Switch off the charger and remove themains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first “positive”, then “negative”).
It is not necessary to disconnect the cables of the battery if you recharge the ve-
hicle battery using low amperages (for example from a mini-charger). Refer to the
instructions of the charger manufacturer .
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower) must be used until full charging is achieved.
It is necessary to disconnect both cables before charging the battery with high
amperages, known as “ rapid charging”.
The vent plugs of the vehicle battery should not be opened for charging.
WARNING“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 152, Jump-starting in vehicles with the START-STOP
system .
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
136General Maintenance
Page 140 of 176
ReplaceFirst read and observe the introductory information and safety warn-
ings
on page 134.
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable vehicle battery types can be purchased from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.
Disconnecting and reconnecting
First read and observe the introductory information and safety warn-
ings
on page 134.
On disconnecting and reconnecting the vehicle battery the following functions
are initially deactivated or are no longer able to operate fault-free:
OperationOperating measureEnter radio code number» Radio manualSetting the clock» page 14Data in the multifunction display are deleted.» page 13
Note
We recommend having the vehicle checked by a specialist garage in order to en-
sure full functionality of all electrical systems.
Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 134.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This manifests itself by the following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where necessary, large convenience consumers such as seat heaters and rear
window heaters have their power limited or are shut off completely in the event of an emergency.
CAUTION
■ Despite such intervention by the vehicle electric system management, the vehi-
cle 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 longer parking.■
Consumers that are supplied via a 12-V power socket can cause the vehicle bat-
tery to discharge when the ignition is switched off.
Note
Driving comfort is not impaired by consumers being deactivated. The driver is of-
ten not aware of it having taken place.

143WARNING■ The national legal regulations must be observed for the use of tyres.■Observe the national legal regulations relating to the use of snow chains
and the maximum vehicle speed with snow chains.WARNINGThe following instructions for the use of tyres must be observed.■For the first 500 km, new tyres do not yet provide optimum grip, and appro-
priate care should therefore be taken when driving – risk of accident!■
Only use radial tyres of the same type, size (rolling circumference) and tread
pattern on all four wheels.
■
For reasons of driving safety, do not replace tyres individually.
■
Never exceed the maximum permissible load bearing capacity for fitted
tyres – risk of accident!
■
Never exceed the maximum permissible speed for fitted tyres – risk of acci-
dent!
■
Incorrect wheel alignment at the front or rear impairs handling – risk of acci-
dent!
WARNING (Continued)■ 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 re-
duce your speed and stop! If no external damage is evident, drive slowly and
carefully to the nearest specialist garage to have the vehicle checked.■
Only use tyres or wheel rims that have been approved by ŠKODA for your
model of vehicle. Failure to observe this instruction may impair the road safety
of your vehicle – risk of accident!
WARNINGObserve the following information regarding tyre damage and wear.■Never use tyres if you do not know anything about the condition and age.■
Never drive with damaged tyres – risk of accident!
■
Immediately replace damaged wheel rims or tyres.
■
You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn down.
■
Worn tyres impair necessary adhesion to the road surface, particularly at
high speeds on wet roads. This could lead to “aquaplaning” (uncontrolled ve- hicle movement – “swimming” on a wet road surface).
WARNINGObserve the following information regarding the tyre inflation pressure.■The tyre control display does not absolve the driver of the responsibility to
ensure the correct tyre inflation pressure. Check the tyre inflation pressure at
regular intervals.■
Insufficient or excessive inflation pressure impairs handling – risk of acci-
dent!
■
If the inflation pressure is too low, the tyre will have to overcome a higher
rolling resistance. This will cause a significant increase in the temperature of
the tyre, especially at higher speeds. This can result in tread separation and a
tyre blowout.
138General Maintenance
Page 142 of 176
WARNINGObserve the following information regarding the wheel bolts.■The wheel bolts must be clean and must turn easily. Never apply grease or
oil.■
The prescribed tightening torque for the wheel bolts is 110 Nm for steel and
light alloy wheel rims.
■
If the wheel bolts are tightened to an insufficient tightening torque, the
rims may come loose when the car is moving – risk of accident! A tightening
torque which is too high can damage the bolts and threads and this can result
in permanent deformation of the contact surfaces on the rim.
■
If the wheel bolts are handled incorrectly, the wheel may come loose when
the car is moving – risk of accident!
WARNINGObserve the following information regarding the spare wheel.■Only use the spare wheel for as long as is necessary.■
Never drive with more than one spare wheel attached.
■
The snow chains cannot be used on the spare wheel.
CAUTION
■ If a spare wheel is used that is not identical to the fitted tyres, the following
must be observed » page 141, Spare wheel .■
Protect the tyres from contact with oil, grease and fuel.
■
Replace lost valve caps.
■
If, in the event of a puncture, it is necessary to fit a spare wheel with a tyre
without a dedicated running direction or with the opposite direction of rotation, drive carefully as the optimal characteristics of the tyre are no longer applicable in
this situation.
For the sake of the environment
Tyres that are insufficiently inflated increase your fuel consumption.
Note
■ We recommend that any work on the wheels or tyres be carried out by a spe-
cialist garage.■
We recommend that you use wheel rims, tyres, full wheel trims and snow chains
from ŠKODA Original Accessories.
Service life of tyresFig. 111
Schematic diagram: Tyre tread with wear indicators/open fuel filler
flap with a table detailing the tyre sizes and tyre inflation pressures
Fig. 112
Replacing wheels
First read and observe the introductory information and safety warn-
ings on page 138.
The service life of tyres depends on the inflation pressure, driving style and other
circumstances. Following the advice below can extend the service life of your
tyres.
Tyre pressure
Check the tyre pressure, including that of the spare wheel, at least once a month and also before setting off on a long journey.
The tyre pressures for tyres are shown on the inside of the fuel filler flap » Fig. 111
– .
The tyre pressure for the spare wheel should correspond to the highest pressure
specified for your vehicle.
139Wheels
Page 143 of 176
Always check the inflation pressure when the tyres are cold. Do not reduce the
higher pressure of warm tyres.
With greater additional load, 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. When driving, however, there are a
range of factors that may result in an imbalance. This may become apparent by a
“vibration” in the steering.
Have the wheels rebalanced after replacing the tyres.
Wheel alignment errors
Incorrect wheel alignment at the front or rear leads to excess wear of the tyres.
Tyre damage
Drive over kerbs and other such obstacles slowly and at right angles wherever
possible 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 (e.g. small
stones) from the tyre tread immediately.
Replacing wheels
If significantly greater wear is present on the front tyres, we recommend replac-
ing the front wheels with the rear wheels as shown in the diagram » Fig. 112 . You
will then obtain approximately the same life for all the tyres.
We recommend that you swap the tyres every 10,000 km in order to achieve even
wear on all tyres and to ensure optimal service life for the tyres.
Storing tyres
Identify disassembled tyres so that the previous direction of rotation can be
maintained if the tyres are reassembled.
Always store wheels or tyres in a cool, dry place that is as dark as possible. Tyres
which are not fixed to a wheel trim should be stored upright.
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. 111 -
. Markings on the
walls of the tyres through the letters “TWI”, triangular symbols or other symbols identify the position of the wear indicators.Tyre age
Tyres age and lose their original characteristics, even if they are not being used.
Therefore, we recommend not using summer or winter tyres older than 6 or 4 years old respectively.
New tyres
First read and observe the introductory information and safety warn-
ings
on page 138.
Only use radial tyres of the same type, size (rolling circumference) and tread pat-
tern on one axle on all four wheels.
The tyre/wheel combinations which are approved for your vehicle are indicated in
your vehicle documents.
Where possible, replace tyres by axle. Always fit the tyres with the deeper tread
depth to the front wheels.

Wheel boltsFirst read and observe the introductory information and safety warn-ings
on page 138.
Wheels and wheel bolts are matched to each other in terms of design. Each time
you fit other wheels rims, e.g. light alloy wheel rims or wheels with winter tyres,
you must also use the matching wheel bolts with the correct length and dome
shape. The right fastening of wheels depends on this.
Winter operation
Introduction
This chapter contains information on the following subjects:
Winter tyres
143
Snow chains
143
Winter tyres
First read and observe the introductory information given on page 143.
Fitting winter tyres will significantly improve the handling of your vehicle when
driving in wintry road conditions. Summer tyres have less grip on ice, snow and at
temperatures below 7 °C. This is especially true of wide tyres or high-speed tyres .
In order to achieve the best possible handling properties, winter tyres must be fit-
ted on all 4 wheels, the minimum tread depth must be 4 mm and tyres must be
no older than 4 years.
Winter tyres of a lower speed category can be used provided that the permissible
maximum speed of these tyres is not exceeded even if the possible maximum speed of the vehicle is higher.
For the sake of the environmentFit the summer tyres on again in good time as they provide better handling prop-
erties, a shorter braking distance, less tyre noise, and reduced tyre wear on roadswhich are free of snow and ice as well as at temperatures above 7 °C. The fuel
consumption is also lower.
Snow chains
First read and observe the introductory information given on page 143.
When driving in wintry road conditions, snow chains improve not only traction,
but also the braking performance.
Snow chains must only be mounted on the front wheels.
For technical reasons, it is only permissible to fit snow chains with the following wheel/tyre combinations.
Tyre sizeRim165/70 R145J x 14 ET 35
Only fit snow chains with links and locks not larger than 15 mm.
Remove the full wheel trims before installing the snow chains.
CAUTION
■
The chains must be removed when driving on roads which are free of snow.
They adversely affect the handling of your vehicle, damage the tyres and are rap-
idly destroyed.■
Remove the full wheel trims before installing the snow chains.

Note■We recommend using a tow rope from ŠKODA Original Accessories, which is
available from a ŠKODA Partner.■
Towing another vehicle requires a certain amount of practice. Both drivers
should be familiar with the particular points about towing a vehicle. Unskilled
drivers should not attempt to tow in another vehicle or to be towed in.
■
When towing, respect the national legal provisions, especially those which re-
late to the identification of the towing vehicle and the vehicle being towed.
■
The tow rope must not be twisted as it may in certain circumstances result in
the front towing eye being unscrewed out of your vehicle.
