Heating and air conditioning system
Heating and air conditioning system
Introductory information
The heating effect is dependent upon the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
If the cooling system is switched on, the temperature and air humidity drops in
the vehicle. The well-being of the occupants of the car is enhanced as a result of
this particularly at high outside temperatures and a high air humidity. The system
prevents the windows misting up during the cold season of the year.
It is possible to briefly activate recirculated air mode to enhance the cooling ef-
fect.
Please refer to the information regarding the recalculated air mode for air-condi-
tioning » page 55.
The air inlet in front of the windscreen must be free of ice, snow or leaves to en-
sure that the heating and cooling system operates properly.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle below the vehicle. This is quite normal
and not an indication of a leak! WARNING
■ For your own safety and that of other road users, ensure that all the win-
dows are free of ice, snow and misting. Please familiarize yourself about how
to correctly operate the heating and ventilation systems, how to demist and
defrost the windows, as well as with the cooling mode.
■ Do not leave recirculated air mode on over a longer period of time, as “stale”
air can cause fatigue of the driver and passengers, reduce attention levels and
also cause the windows to mist up. The risk of having an accident increases.
Switch off recirculated air mode as soon as the windows start to mist up. Note
■ The used air streams out through the vents in the luggage compartment.
■ We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the in-
terior of the vehicle forms deposits in the evaporator of the air conditioning sys-
tem. This produces a permanent odour when the air conditioning system is oper-
ating which can only be eliminated through considerable effort and expense (re-
placement of compressor).
■ To ensure that the heating and air conditioning systems work properly, do not
block up the air outlet vents with any objects. Ð Using the air conditioning system economically
The compressor on the air conditioning system uses power from the engine when
in cooling mode which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the inte-
rior has been strongly heated through the effect of direct sunlight in order to al-
low the heated air to escape.
The cooling system should not be switched on while travelling when the window
is open.
If the desired interior temperature can also be achieved without activating the
cooling system, fresh air mode should be selected. For the sake of the environment
Pollutant emissions are also reduced when fuel is saved. Ð Operational problems
If the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be.
› One of the fuses has blown. Check the fuse and replace if necessary
»
page 138.
› The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot » page 13.
If you cannot rectify the functional fault yourself, or the cooling capacity decrea-
ses, the cooling system must be switched off. Visit a ŠKODA specialist garage. Ð

WARNING
■ 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 ŠKODA
specialist garage to correct the fault on the gas
system.
■ The following is 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. WARNING (Continued)
■ A natural gas-powered vehicle must be shut down if no periodic testing of
pressure accumulators is performed or an approved component has been re-
placed by a non-approved component. 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 enclosed storage places, garages and similar
areas where it is specifically not allowed to enter with CNG-powered vehicles. Ð Refuelling

Fuel filler
First read and observe the introductory information and safety warn-
ings on page 106.
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.

106 General Maintenance

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
