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 84 or for Climatronic »
page 86.
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 boot.
■ 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 necessa-
ry »

page 190 .
› The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot » page 9.
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

Climatronic (automatic air conditioning system)
Introductory information
The Climatronic maintains fully automatically a convenience temperature. This is
achieved by automatically varying the temperature of the air flow, the blower
stages and air distribution. The system also takes sunlight into account, which
eliminates the need to alter the settings manually. The automatic
mode » page 86
ensures maximum well-being of the occupants at all times of
the year.
Description of Climatronic system
The cooling system only operates if the following conditions are met:
› engine running;
› outside temperature above approx. +2 °C;
› AC 13

lights up, the Climatronic operates in “HIGH” mode. The “HIGH” mode is
the standard setting of the Climatronic.
When pressing again the button AUTO , the Climatronic changes into the “LOW”
mode and the warning light in the top left corner lights up. The Climatronic uses
only in this mode the lower blower speed. However taking into account the noise
level, this is more comfortable, yet be aware that the effectiveness of the air con-
ditioning system is reduced particularly if the vehicle is fully occupied.
By pressing the button AUTO again, it is changed to “HIGH” mode.
Automatic mode is switched off by pressing one of the buttons for the air distri-
bution or by increasing/decreasing the blower speed. The temperature is never-
theless regulated. ÐSwitching the cooling system on and off

. The
warning light in the button goes out.
The interior temperature can be set between +18 °C and +26 ℃. The interior tem-
perature is regulated automatically within this range. If a temperature lower than
+18 °C is selected, a blue symbol lights up at the start of the numerical scale. If a
temperature higher than +26 °C is selected, a red symbol lights up at the start of
the numerical scale. In both limit positions the Climatronic operates at maximum
cooling or heating capacity, respectively. The temperature is not controlled in this
case.
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. Ð 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. If a considerable increase in concentration of pollutants is rec-
ognized by the air quality sensor, when the automatic air distribution control is
switched on, the air distribution control will temporarily be switched off. If the
concentration of pollutants decreases to the normal level, the air distribution con-
trol 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 in air. £

Auxiliary heating (parking heating)
The auxiliary heater (parking heater) functions in connection with the air-condi-
tioning system or Climatronic.
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).
The engine is also preheated, if the auxiliary heating is switched on when the ve-
hicle is stationary and the engine is switched off. £
