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 standing in a traffic jam. Switching recirculated air mode on
– Press switch

Recirculated air mode is switched off automatically if the air distribution
control is in position  ⇒ page 100, fig. 94 . You can also switch recir-
culated 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 occu-
pants, divert your attention and al so 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.

Redirecting air flow
– The horizontal as well as the vertical direction of the air flow is
set with the handle in the middle of the air outlet vents.
You can set the air supply to the individual vents with the air distribution
control ⇒page 100, fig. 94 . Air outlet vents 3 and 4 can also be
opened or closed individually:
Unwarmed or cooled air will flow out of the air outlet vents according to the
setting of control dial ⇒page 100, fig. 94 and the atmospheric
conditions.
Using the air conditioni ng system economically
The compressor on the Climatic 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 problems
If the cooling system does not operate at outside temperatures higher
than +2 °C, there is a problem in the system. The reasons for this may be:
•The fuse of the Climatic is defective. Check the fuse, replace it if
necessary ⇒page 249.
•The cooling system has switched off automatically for a short time
because the coolant temperature of the engine is too hot ⇒page 14.
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 combination of an automatic
heating, fresh air and cooling system which provides
optimal comfort for the occupants of the car.
The Climatronic maintains a constant temperature fully automatically,
once it has been set. This is achieved by automatically varying the
temperature of the outflowing air, the blower stages and the air distribu-
tion. The system also takes into account sunlight which eliminates the
need to alter the settings manually. The automatic mode ⇒ page 106
ensures maximum wellbeing of the occupants at all times of the year.
Description of Climatronic system
The cooling operates only if the following conditions are met:
•engine running,
•outside temperature above +2 °C,
•the button is not pressed.
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 particularly at high outside temperatures and a high air
humidity. The system prevents the windows misting up during the cold
season of the year.
The heating effect is dependent upon the coolant temperature, thus full
heat output only occurs when the engine has reached its operating
temperature.
It is possible to briefly activate recirculated air mode in order to enhance
the cooling effect ⇒. 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 high 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 conditioning may drip down and form a puddle below the vehicle. This
is quite normal and not an indication of a leak!
Recommended setting for all periods of the year:
•Set the temperature to 22 °C.
•Press the button ⇒page 105, fig. 96 .
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly
upwards ⇒page 108, fig. 97 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒page 105, fig. 96 . The
information in the desired temperature measuring unit appears in the
display.
WARNING
•For 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 correctly operate the 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 recircu-
lated 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 minutes
at the highest blower stage - also during the cold season of the year - in
order to remove such odours. Also open a window for a short time.
•We recommend that you do not smoke in the vehicle when the recir-
culating air mode is operating since the smoke which is drawn at the evap-
orator from the interior of the vehicle forms deposits in the evaporator 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 compartment.

Setting temperature
– You can set the desired interior temperature after switching on the ignition with the control dial .
You can set the interior temperature between +18°C and +29°C. The inte-
rior temperature is regulated automatically within this range. If you select
a temperature of less than +18 °C, “LO” is shown on the display. If you
select a temperature above +29 °C, “HI” is shown on the display. 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 (in partic-
ular at the leg area) and large differences in temperature, for example
when getting out of the vehicle, can result in chills in sensitive persons.
Controlling blower
There are a total of seven blower stages available.
The Climatronic system controls the blower stages automatically
in line with the interior temperature. You can also, however, adapt
the blower stages manually to suit your particular needs.
– Turn the control dial ⇒page 105, fig. 96 to the left (reduce
blower speed) or right (increase blower speed).

Towing a trailer
Towing a trailer
Technical requirements
The towing device must satisfy certain technical require-
ments.
Your vehicle is designed primarily for transporting persons and luggage. It
can, however, also be used for towing a trailer - provided certain technical
equipment is fitted.
If your vehicle has already been supplied with a factory-fitted towing
device then everything that is necessary for towing a trailer in technical
terms, and in terms of the law, has already been taken into account.
Your vehicle is fitted with a 13-pin power socket for the electrical connec-
tion between the vehicle and trailer. If the trailer which you wish to tow has
a 7-pin connector , you can use a suitable adapter
5) from Škoda original
accessories.
This work must be carried out in accordance with the manufacturer's
specifications if a towing device is retrofitted.
Škoda Service Partners are familiar with details relating to retrofitting a
towing device and for any necessary modifications to the cooling system.
WARNING
We recommend that you have the towing device from Škoda orig-
inal accessories installed by a Škoda Service Partner. He is familiar
with all the relevant details relating to retrofitting such equipment.
There is a risk of an accident if the towing device is not properly
fitted!
General Maintenance
There are a number of points to pay attention to when
towing a trailer.
Tr a i l e r l o a d
The permissible trailer load must on no account be exceeded.
You can negotiate appropriately steeper inclines and descents if you do
not make full use of the permissible trailer load.
The trailer loads specified only apply for altitudes up to 1 000 metres
above mean sea level. The fact that the engine power output drops with
increasing height due to a lowering of air pressure and thus the ability to
climb, means that the towed weight must be reduced by 10% for every
further increase of 1 000 metres in height above sea level. The towed
weight is the weight of the (laden) vehicle and the (laden) trailer together.
One should take this into account before driving up to higher altitudes.
The trailer and drawbar load information on the type plate of the
towing device are merely test data for the towing device The data
relating to your vehicle, which is often less than this test data, can
5)In some countries the adapter is supplied with the towing device.

You must always reduce your speed immediately as soon as you detect
even just the
slightest swaying of the trailer. On no account attempt to
stop the trailer from “swaying” by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake,
apply the brakes gently at first and then brake firmly. This will avoid brake
jolts resulting from the trailer wheels locking. Shift down gears in good
time before negotiating a downhill section to allow the engine to also act
as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to
negotiate a lengthy slope in a low gear at a high engine speed when the
outside temperature is very high ⇒page 14.
If the needle of the coolant temperature gauge moves into the right-hand
area or even the red area of the scale, reduce your speed immediately.
Stop and switch off the engine if the warning light
 in the instrument
cluster begins flashing. Wait a few minutes and check the level of coolant
in the coolant expansion bottle ⇒page 216, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 31, “Coolant tempera-
ture/coolant level ”.
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down
a gear and increasing the engine speed is not possible since the fan
speed is independent of the engine speed. One should also not drop a
gear for this reason when towing a trailer as long as the engine can
manage the slope without any drop in speed.
