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.

the temperature is automatically not regulated.
CAUTION
Lengthy and uneven distribution of the air flow out of the vents (especially
around the feet) and large differences in temperature, for example, when getting
out of the vehicle, can cause susceptible individuals to catch a cold.
Automatic recirculated air mode
Recirculated air mode largely prevents polluted air from outside the vehicle get- ting into the vehicle, for example, when driving through a tunnel or when stand-
ing in a traffic jam. 
87Heating and air conditioning system

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.

Function prerequisites when switching on:
› Comfort temperature has been set;
› The blower is switched on;
› the air outlet vents are opened;
› The air outlet is set to position

or 
.
Auxiliary heating (parking heating) › It can be used when stationary, when the engine is switched off to preheat the
vehicle and while driving (e.g. during the heating phase of the engine);
› It works in tandem with the hearer, air-conditioning system or Climatronic;

88Using the system

›The engine is also preheated when the vehicle is stationary and the engine is
not running;
› It warms up the coolant by burning fuel from the vehicle tank. The coolant
warms up the air, which (if the blower speed is not set to zero) flows into the passenger compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).WARNING■ The auxiliary heating must never be operated in closed rooms - risk of poi-
soning!■
The auxiliary heating must not be running during refuelling - risk of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore, if you wish to operate the auxiliary heating, do not park the vehicle in such a way that the exhaust gases can come into contact with high-
ly flammable materials (e.g. dry grass) or easily inflammable substances (e.g.
spilt fuel).
CAUTION
■ The running auxiliary heater consumes fuel from the vehicle tank and automati-
cally controls the filling level. If only a low quantity of fuel is present in the fuel
tank, the function of the auxiliary heating is blocked.■
The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
■
If the auxiliary heating and ventilation is running, the vehicle battery discharges.
If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometres in order to recharge
the vehicle battery.
Note
■ The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating problem.
■
The air inlet in front of the windscreen must be free of e.g. ice, snow or leaves
to ensure that the auxiliary heating and cooling system operates properly.

radio remote control.
›
Insert a flat, blunt object, such as a coin, into the gap of the battery cover.
›
Turn the cover against the direction of the arrow up to the mark to open the cover.
›
Replace the battery.
›
Return the battery cover.
›
Turn the cover in the direction of the arrow up to the initial marking, engage.

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.
