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 ⇒page 81, fig. 95 the switch symbol  lights up.
Switching recirculated air mode off
– Press button again, the button symbol  goes out.
The recirculated air mode is switched off au tomatically if the air distribution control is in position  ⇒page 81, fig. 95. 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 attention and also cause the windows to mist up. The risk of having an acci-dent 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 81, fig. 95. Air outlet vents 3 and 4 can also be opened or closed individu- ally:
Unwarmed or cooled air will flow out of the air outlet vents according to the setting of control dial ⇒page 81, fig. 95 and the atmospheric conditions.
Using the air conditioning 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 th e doors of a vehicle for which the inte- rior has been strongly heated through the ef fect 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 207.
•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 rectify the operat ional problem yourself, or if the cooling capacity decreases, switch the cooling sy stem off. Contact a specialist garage.
If there is a fault at the Climatronic, all symbols on the display flash after switching on the ignition for 15 seconds. 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 temper ature fully automatically, once it has been set. This is achieved by automa tically varying the temperature of the outflowing air, the blower stages and the air distribution. The system also takes into account sunlight which eliminates the ne ed to alter the settings manually. The automatic mode ⇒page 86 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 th e coolant temperature, thus full heat output only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirc ulated 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 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 below the vehicle. This is quite normal and not an indication of a leak!
Recommended setting for al l periods of the year:
•Set the temperature to 22 °C.
•Press the button ⇒fig. 97.
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards ⇒ page 88, fig. 98.
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒fig. 97. 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 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 mi nutes 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 recirculating air mode is operating since the smoke which is drawn at the evaporator from the inte- rior of the vehicle forms deposits in the ev aporator of the air conditioning system. This produces a permanent odour when th e air conditioning system is operating which can only be eliminated through co nsiderable effort and expense (replace- ment of compressor).
•The used air streams out through the air removal openings in the luggage compartment.

Towing a trailer160
Towing a trailer
To w i n g a t r a i l e r
Technical requirements
The towing device must satisfy certain technical requirements.
Your vehicle is designed primarily for transporting persons and luggage. It can, however, also be used for towing a traile r - provided certain technical equipment is fitted.
If your vehicle has been eq uipped with a towing device from Škoda Original Acces- sories, then the towing device satisfies all technical and legal requirements.
Your vehicle is fitted with a 13-pin po wer socket for the electrical connection between the vehicle and trailer. If th e 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 accordan ce with the manufacturer's specifications if a towing device is retrofitted.
Škoda Service Partners are familiar with de tails relating to retrofitting a towing device and for any necessary modi fications to the cooling system.
WARNING
We recommend that you have the towing device from Škoda original acces- sories installed by a Škoda Service Partner. He is familiar with all the relevant details relating to retrofitting such equi pment. 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.
Trailer load
The permissible trailer load must on no account be exceeded.
You can negotiate appr opriately steeper inclines and descents if you do not make full use of the perm issible 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 ou tput drops with increasing height due to a lowering of air pressure and thus the abil ity 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 alti- tudes.
The trailer and drawbar load information on the type plate of the towing device are merely test data for the tow ing device The data relating to your vehicle, which is often less than this test data, can be found in your vehicle registration documents.
Distribution of the load
Distribute the load in the trailer in such a way that any heavy items are located as close as possible to the axle. Secure the items to prevent them slipping.
Tyre pressure
Correct the tyre inflation pressure on yo ur vehicle for that of “fully laden”, ⇒ page 187. The inflation pressure of the tyres fitted to the trailer adjust in accord- ance with the manufacturer's recommendation.
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see the traffic behind the trailer with the standard rear-view mirrors. Both exterior mirrors 5)In some countries the adapter is supplied with the towing device.

should be attached to folding arms. Adjust the mirrors so that they provide you with an adequate field of view to the rear.
Headlights
Before starting off with a hitched trailer, also check the setting of the headlights. Alter the setting as necessary with th e aid of the headlight beam adjuster ⇒ page 46.
Detachable ball head
The ball rod is detachable on vehicles with towing device and suppliable from Škoda original accessories. It is stowed together with separate fitting instructions in the spare wheel well in the luggage compartment of the vehicle.
Note
•We recommend that you also have yo ur vehicle inspected between service intervals if you tow a trailer frequently.
•The handbrake on the towing vehicle must be put on when coupling and decoupling the trailer.
Driving Tips
Particular caution is required when towing a trailer.
– Do not, as far as possible, drive with your vehicle unladen and the
trailer laden.
– Do not make full use of the legal maximum speeds. This applies in
particular to downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temper ature gauge if the outside temper-
ature is high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer is laden. Maintain a particularly low speed if you cannot avoid driving with this combination.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for coun- tries in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with increasing speed means that the legally allowed speed should not be used when there are unfavourable road, weather or wind conditions, particularly near accident black spots.
You must always reduce your speed immedi ately 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 down- hill 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 10.
If the needle of the coolant temperature gauge moves into the right-hand area or even the red area of the scale, reduce yo ur speed immediately. Stop and switch off the engine if the warning light  in the instrument cluste r begins flashing. Wait a few minutes and check the level of coolant in the coolant expansion bottle ⇒ page 179, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 24, “Coolant temperature/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

Inspecting and Replenishing174
– Grip the bonnet and lift it up.
– Take the bonnet support out of its holder and set it in the opening
designed for it ⇒page 173, fig. 156.
Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the
bonnet support into the hold er designed to hold it.
– Allow the bonnet to drop from a height of about 30 cm into the lock -
bonnet do not press down on it!
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of the engine compartment - risk of scaldi ng! Wait long enough until the steam or coolant has stopped escaping.
•For safety reasons, the bonnet must always be properly closed when driving. One should therefore check that the lock has in fact engaged prop- erly after closing the bonnet.
•Stop your vehicle i mmediately while driving if you notice that the lock is not properly engaged and close the bonn et properly - risk of an accident!
Caution
•Before opening the bonnet, ensure that the arms of the windscreen wipers are correctly in place against the windscreen. Otherwise, there is a risk of damage to the paintwork.
Working in the engine compartment
Particular care is required when ca rrying out any work in the engine
compartment!
There is a risk of injuries, scalding, accidents and fire when working in the engine compartment, e.g. inspecting an d replenishing oil and other fluids. For
this reason, it is essential to comply with the warning instructions stated below and with the general applicable rules of safety. The engine compart-ment of your car is a hazardous area ⇒.
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of the engine compartment - risk of scaldi ng! Wait long enough until the steam or coolant has stopped escaping.
•Switch off the engine and pull out the ignition key.
•Apply the handbrake firmly.
•If your vehicle is fitted with a manual gearbox, move the gearshift lever into Neutral, or if it is fitted with automatic gearbox, move the selector lever into position P.
•Allow the engine to cool down.
•Keep children clear of the engine compartment.
•Do not touch any hot engine parts - risk of burns!
•Never spill oil and other fluids over the hot engine. Such fluids (e.g. the antifreeze contained in the coolant) may ignite!
•Avoid short circuits in the electrical system - particularly on the battery.
•Never place your hand into the radiator fan as long as the engine is still warm. The fan might suddenly start running!
•Never open the cap of the coolant expa nsion bottle as long as the engine is still warm. The cooling system is pressurized!
•Cover over the cap of the coolant expansion reservoir with a large cloth when opening it as protection for your face, hands and arms from hot steam or hot coolant.
•Do not let objects, such as e.g cleaning cloth or tools lie in the engine compartment.
•If you wish to work under the vehicl e, you must secure the vehicle from rolling away and support it with suitable supporting blocks: the car jack is not sufficient for this - risk of injury!
•In cases where it be necessary to carry out inspection work when the engine is running there is an additional risk from rotating parts (e.g. the V-
