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 recirculated air mode for the air-condi- tioning system » page 85 or for Climatronic » page 87.
The air inlet in front of the windscreen must be free of e.g. ice, snow or leaves to ensure 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 not a leak!
WARNINGFor your own safety and that of other road users, ensure that all the windows
are free of ice, snow and misting. Please familiarize yourself about how to cor-
rectly operate the heating and ventilation systems, how to demist and defrost
the windows, as well as with the cooling mode.
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).

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.
For the sake of the environment
Pollutant emissions are also reduced when fuel is saved » page 101, Economical
and environmentally friendly driving .
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 necessa-
ry » page 200 .
› The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot » page 10.
If you are not able to resolve the operational fault yourself, or if the cooler output has reduced, switch off the cooling system and get assistance from a ŠKODA Spe- cialist garage.

Air conditioning system (manual air conditioning
system)
Introductory information
The cooling system only operates if the button 

» Fig. 85 on page 84 is press-
ed, and the following conditions are met:
› engine running;
› outside temperature above approx. 2
℃;
› blower switch switched on (positions 1-6).
Under certain circumstances, air at a temperature of about 5 °C can flow out of
the vents when the cooling system is switched on. Lengthy and uneven distribu-
tion of the air flow out of the vents and large differences in temperature, for ex-
ample when getting out of the vehicle, can result in chills in sensitive persons.
If the desired interior temperature can also be achieved without activating the
cooling system, fresh air mode should be selected.
Note
We recommend that you have the air conditioning system cleaned by a ŠKODA
specialist garage once every year.

If a considerable increase in concentration of pollutants is recognised by the air
quality sensor, recirculated air mode will temporarily be switched off.
If the concentration of pollutants decreases to the normal level, the air distribu-
tion control is automatically switched off so that fresh air can be guided into the
vehicle interior.
In recirculated air mode air is sucked out of the interior of the vehicle and then
fed back into the interior. When the automatic air distribution control is switched on, an air quality sensor measures the concentration of pollutants in the drawn inair.
If the air quality sensor does not switch on automatic recirculated air mode when there is an unpleasant smell, you can switch in on manually.
Switching on/off›

WARNINGDo 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.

Avoiding full throttleFig. 96
Principle sketch: Fuel consump-
tion in litres/100 km. and speed
in km/h
The slower you drive, the more the fuel savings.
Sensitive use of the accelerator will not only significantly reduce fuel consump- tion but also positively influence environmental pollution and wear of your vehi-
cle.
The maximum speed of your vehicle should, as far possible, never be used. Fuel
consumption, pollutant emissions and vehicle noises increase disproportionally at
high speeds.
The » Fig. 96 shows the ratio of fuel consumption to the speed of your vehicle.
Fuel consumption will be halved if only three-quarters of the possible top speed
of your vehicle is used.

Reducing idling
Idling also costs fuel.
In vehicles not equipped with the START-STOP system, turn off the engine when
in a traffic jam, at a level crossing or traffic lights with longer wait times.
Even after just 30-40 seconds you will have saved more fuel than that is needed
when you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant emissions, though, are particularly
high in the warming-up phase. Therefore, start driving as soon as the engine has
started. whereby high engine speeds should be avoided.

Avoid short distancesFig. 97
Principle sketch: Fuel consump-
tion in l/100 km at different tem-
peratures
Short distances result in an above-average high fuel consumption. We therefore recommend avoiding distances of less than 4 km if the engine is cold.
A cold engine consumes the most fuel immediately after the start. Fuel consump- tion drops to 10 litres/100 km after just 1 kilometre. The consumption stabilises once the engine and catalytic converter have reached their operating tempera-
ture.
An important factor in this connection is also the ambient temperature. The im-
age » Fig. 97 shows the different levels of fuel consumption after driving a certain
distance at a temperature of +20 °C and a temperature of -10 °C.
Your vehicle has a higher fuel consumption in Winter than in Summer.
