Recirculated air mode
In recirculated air mode air is sucked out of the interior of the vehicle
and then fed back into the interior.Recirculated air mode prevents polluted air outside the vehicle from getting into the
vehicle, for example when driving through a tunnel or when standi ng in a traffic jam.Switching recirculated air mode on– Press the button page 98, fig. 107 the warning light lights up in the
button.Switching recirculated air mode off– Press again the button - the warning light in the button goes out.
The recirculated air mode is switched off automatically if the air distribution control
is in position
  page 98, fig. 107. You can also switch recirculated air mode on
again from this setting by repeatedly pressing button .
WARNING
You should not leave recirculated air mode on over a longer period of time, as
“stale” air may result in fatigue in the driver and occupants, divert your atten-
tion and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mode off as soon as the windows begin
misting up.Using the air conditioning system economicallyThe compressor on the air conditioning syst em 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 interior
has been strongly heated through the effect of direct sunlight in order to allow the
heated air to escape.
The cooling system should not be switched on while travelling when the window is
open. The desired interior temperature can also be achieved without switching in the cooling
system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you
also reduce pollutant emissions.Operational malfunctionsIf 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:
The fuse on the air conditioning system has blown. Check the fuse, replace it if
necessary page 226.

The cooling system has switched off auto matically for a short time because the
coolant temperature of the engine is too hot  page 16.
If you are not able to rectify the operational problem yourself, or if the cooling capacity
decreases, switch the cooling system off. Contact a specialist garage.
Climatronic* (automatic air conditioning)Description
The Climatronic system is a combinat ion of an automatic heating, fresh
air and cooling system which provides optimal comfort for the occu-
pants of the car.The Climatronic maintains fully automatically a convenience temperature. This is
achieved by automatically varying the temperature of the outflowing air, the blower
stages and the air distribution. The system also takes into account sunlight which elim-
inates the need to alter the settings manually. The automatic mode  page 102
ensures maximum wellbeing of the occupants at all times of the year.

outside temperature above approx. +2°C,

switched on.
If the cooling system is switched on, the temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this partic-
ularly at high outside temperatures and a high air humidity. The system prevents the
windows misting up during th e cold season of the year.
The heating effect is dependent upon the c oolant temperature, thus full heat output
only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculat ed air mode in order to enhance the cooling
effect page 103.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to
ensure that the heating and cooling systems operate properly.
The AC compressor is switched off at a hi gh coolant temperature in order to provide
cooling at a high load of the engine.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle be low the vehicle. This is quite normal and
not an indication of a leak!
Recommended setting for all periods of the year:

Set the desired temperature, we recommend 22°C.

Press the button page 102, fig. 108 .

Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards.
WARNING

For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin g. Please familiarize yourself about
how to correctly operate th e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.

You should not leave recirculated air mode on over a longer period of time,
as “stale” air may result in fatigue in the driver and occupants, divert your
attention and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mode off as soon as the windows begin
misting up.
Note

If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of deposits. Switch the cooling system on at
least once a month for approximately 5 minu tes at the highest blower stage - also
during the cold season of the year - in order to avoid such odours. Also open a window
for a short time.

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 interior
of the vehicle forms deposits in the evapor ator of the air conditioning system. This
produces a permanent odour when the air conditioning system is operating which can
only be eliminated through considerable effort and expense (replacement of
compressor).

The used air streams out through the air removal openings in the luggage compart-
ment.

On vehicles equipped with a factory-fitted radio* or navigation*, the information
of the Climatronic is also shown on the display. This function can be switched off, see
operating instructions of the radio* or the navigation system*.

The automatic mode is used in orde r to maintain a constant tempera-
ture and to demist the windows in the interior of the car.Switching automatic mode on– Set a temperature between +18 °C and +26 °C.
– Move the air outlet vents 3 and 4  page 94, fig. 104, so that the air flow is directed
slightly upwards.
– Press the button . In the right or left top corner a warning light lights up, depending on which unit was last selected.
If the warning light in the top right corner of the button lights up, the
Climatronic operates in “HIGH” mode. The “HIGH” mode is the standard setting of the
Climatronic.
When pressing again the button , the Cl imatronic changes into the “LOW” mode
and the warning light in the top left corner li ghts 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 conditioning system is
reduced particularly if th e vehicle is fully occupied.
By pressing again the button , you change into the “HIGH” mode.
The automatic mode is switched off by pressing the button for the air distribution or
increasing or decreasing the blower speed. The temperature is nevertheless
regulated.

switching cooling on and offswitching cooling on and off–Press the button page 102, fig. 108 . The warning light lights up in the button.
– When you again press the switch , the cooling system is switched off. The warning light in the button goes out. Only the function of the ventilation remains
active when no lower temperature than the outside temperature can be reached.Setting temperatureYou can separate the interior temperature for the left and right side separately.
– You can set the temperature for both sides after switching on the ignition with the
control dial .
– If you wish to set the temperature for the right side, turn the control dial . The warning light in the button lights up, this indicates that differing tempera-
tures for the left and right side can be set.
If the warning light in the button lights up, the temperature for both sides
cannot be set with the control dial . You can reinitiate this function by pressing the
button . The warning light in the button which indicates the possibility to set
differing temperatures for the left and right side, goes out.
You can set the interior temperature between +18°C and +26°C. The interior temper-
ature is regulated automatically within this range. If you chose a temperature lower
than +18°C, a blue symbol lights up at the start of the numerical scale. If you chose a
temperature higher than +26°C, a red symbol lights up at the end of the numerical
scale. In both limit positions the Climatroni c operates at maximum cooling or heating
capacity, respectively. The temperatur e is not controlled in this case.
Lengthy and uneven distribution of the air flow out of the vents (in particul ar at the leg
area) and large differences in temperature, for example when getting out of the vehicle,
can result in chills in sensitive persons.
Recirculated air mode
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.Recirculated air mode prevents polluted air outside the vehicle from getting into the
vehicle, for example when driving through a t unnel or when standing in a traffic jam. If
a considerable increase in concentration of pollutants is recognized by the air quality
sensor, when the automatic air distribution co ntrol 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 control is automatically switched off so that fresh
air can be guided into the vehicle interior.Switching recirculated air mode on– Press the button repeatedly until the warning light on the left side of the
button lights up.Switch on automatic air distribution control– Press the button repeatedly until the warning light on the right side of the
button lights up.Switch off automatic air distribution control temporarily– If the air quality sensor does not switch on the air distribution control automatically when there is a nauseating smell, you can switch it on yourself by pressing the
button *. The warning light lights up in the button on the left side.Switching recirculated air mode off– Press the button or press the bu tton repetitively, until the warning
lights in the button go out.

the windscreen has been demisted, press the button .

The automatic air distribution control oper ates only if the outside temperature is
higher than approx. 2°C.
Controlling blower
There are a total of seven blower stages available.The Climatronic system controls the blower stages automatically in line with the inte-
rior temperature. You can also , however, a dapt the bl ower stages ma nua lly to suit y our
particular needs.
– Press again the button on the left side (reduce blower speed) or on the right side (increase blower speed).
If you switch off the blower, th e Climatronic is switched off.
The set blower speed is displayed above the button when the respective number
of warning lights come on.
WARNING

“Stale air” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an accident
increases.

Do not switch the Climatronic system off for longer than necessary.

The auxiliary heating (auxiliary he ating and ventilation) heats or
supplies the interior of the vehicl e with fresh air independent of the
engine.Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) functions in connection with the Climatic or
Climatronic.
It can be used when stationary, when engi ne is switched off for preheating of the
vehicle as well as while driving (only during the heating phase of the engine).
The auxiliary heating (auxiliary heating) wa rms up the coolant during the combustion
of fuel from the vehicle tank. The coolant warms up the air, which (if the blower speed
is not set to zero) flows into the occupant 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 decreased (e.g. with the
vehicle parked in the sun).

WARNING

The auxiliary heating must never be operated in closed rooms - risk of
poisoning!

The auxiliary heating must not be runn ing during refueling - risk of fire.

The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore do not place the vehicl e, if you wish to operate the auxiliary
heating, in such a way that the exhaust gases of the auxiliary heating can come
easily into contact with inflammable mate rials (e.g. dry grass) or easily inflam-
mable substances (e.g. fuel run out).Note

If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
Therefore the auxiliary heating should not be op erated, if there is very little fuel in the
tank.

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 be en operated several times over a longer
period, the vehicle must be driven a few ki lometers in order to recharge the vehicle
battery.

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.

After switching off the auxiliary heating, the coolant pump runs for a short period.

The auxiliary heating and ventilation does not switch on or comes on, if the vehicle
battery indicates a low loading state.

The auxiliary heating (auxiliary heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please refuel!
(Please refuel!) .

The air inlet in front of the windscreen must be free of ice, snow or leaves in order
to ensure that the auxiliary heating operates properly.

So that warm air can flow into the vehicl e interior after switching on the auxiliary
heating, you must maintain the temperature normally selected by you (we recom-
mend 22°C). It is recommended to put the air flow in the position
.

On vehicles with DPF (diesel particle filter) the warm coolant heats up the engine.
Direct switching on/offThe auxiliary heating (auxiliary heating and vent ilation) can be switched on or off at any
time directly using the button on the operating part of the Climatic fig. 109 or
on the operating part of the Climatronic.
If the auxiliary heating and ventilation is not switched off earlier, it switches off auto-
matically after the expiration of the set operating period, in the menu Running time.Using the system
So that the auxiliary heating (auxiliary heating and ventilation) func-
tions according to your expectations, it is necessary to carry out the
basic setting before its programming.Basic setting– On the information display, select from the Main menu the menu point
Aux. heating .
– In the menu Aux. heating select the menu point Weekday and set the current day.
– Return to a higher level by selecting the menu point Back, i. e. in the menu

– In the menu Aux. Heating select the menu point Running time and set the
desired operating period in steps of 5 m inutes. The running time can be 10 to 60
minutes.
– By selecting the menu point Back, you will reach in the menu Aux. Heating.
– In the menu Aux. heating select the menu point Mode.
– In the menu Mode select the desired mode Heating for or Ventilation for .ProgrammingFor the programming of the auxiliary heating (auxiliary heating and ventilation) in the
menu Aux. heating there are three pre-set times:
Pre-set time 1

Pre-set time 2

Pre-set time 3
In each pre-set time, the day and the time (hour and minute) can be set for switching
on the auxiliary heating and/or ventilation.
An empty position can be fo und between Sunday and Monday when selecting the day.
If this empty position is selected, the activation is performed without taking into
account the day.
If you leave the pre-set menu by selecting the menu Back or do not make changes on
the display for longer than 10 seconds, the set values are stored, but the pre-set time
is not active.
Both other pre-set times can be programmed and stored in the same way.
If you select the menu Activate after setting the desired values, appears on the display
Pre-set time (weekday, hours, minute) activated! and the set pre-set time is active.
Only one programmed pre-set time can be active.
The last programmed pre-set time remains active.
After the auxiliary heating activates at the set time, it is necessary to pre-set a time
again.
Changing the active pre-set time is carried out after selecting the menu point Activate
in the menu Aux. heating by selecting a pre-set time. The prerequisite for the correct switching on
of the auxiliary heating (auxiliary heating
and ventilation) according to the programmed pre-set time is the correct setting of the
current time and the weekday page 105.
If the system is running, a warning light in th e button for direct switching on/off of the
auxiliary heating lights up.
The running system deactivates after expirati on of the operating period or is deacti-
vated earlier by pressing the button for direct switching on/off of the auxiliary heating
 page 105.
A random pre-set time can be deactivated by selecting the menu point Deactivate in
the menu Activate.
After selecting the menu point Fa ct or y se t ti ng in the menu Aux. heating , it is possible
to return to the factory setting.

Checking tyre inflation pressures
Tyres which are correctly inflated save fuel.Always ensure that your tyres are inflated to the correct pressure at all times. The rolling
resistance will be increased if the tyre filling pressure is too low. This will not only
increase fuel consumption but also tyre we ar and the driving behaviour will worsen.
Always check the inflation pr essure of the tyres when cold.
Do not drive with winter tyres all year round for this costs about 10 % more fuel.
Winter tyres are also louder.No unnecessary ballast
Transporting ballast costs fuel.The fact that every kilogram of extra weight increases your fuel consumption means
that it is worth taking a look in the luggage compartment to avoid transporting any
unnecessary ballast.
It is particularly in town traffic, when one is accelerating quite often, that the vehicle
weight will have a significant effect upon the fuel consumption. A rule of thumb here
is that an increase in weight of 100 kilograms will cause an increase in fuel consump-
tion of about 1 litre/100 kilometres.
You may frequently also leave a roof rack fitted on just out of convenience, although
you no longer need it. The increased aerodyna mic drag of your vehicle causes it to use
about 10% more fuel than normal at a speed of 100 - 120 km/h, even when you are not
carrying a load on the roof.Saving electricity
Generating electricity costs fuel.– Switch off electrical components as soon as you no longer need them.
When the engine is running, the alternator generates and supplies electrical power.
The greater the load on the alternator as a result of having a large number of electrical
components switched on, the more fuel will be consumed for operating the
alternator.
Keeping a log of your fuel consumptionIf you really wish to keep a close check on your fuel consumption, it is best to enter
the figures in a logbook. This does not take much time but is a very worthwhile exer-
cise. It enables you to detect any change (p ositive and negative) at an early stage and
to take any appropriate action.
If you find that your fuel consumption is too high, you should reflect on how, where
and in what conditions you have driven the vehicle since you last refuelled.Environmental compatibilityEnvironmental protection has played a major role in the design, selection of materials
and manufacture of your new Škoda. Particular emphasis has been paid to a number
of aspects, including:
Design measures
Joints designed to be easily detached.

Simplified disassembly due to the modular structure system.

Improved purity of differ ent classes of materials.

Identification of all plastic parts in accordance with VDA Recommendation°260.

Reduced fuel consumption and exhaust emission CO
2.

Minimum fuel leakage during accidents.

Reduced noise.
Choice of materials

Extensive use of re cyclable material.

Air conditioning filled with CFC-free refrigerant.

No cadmium.

No asbestos.

Reduction in the “vaporisation” of plastics.
Manufacture

Solvent-free cavity protection.
