arranged thumbwheel.
– Turn the horizontal thumbwheel on the vent to the right or left in order to change the air flow to the appropriate side.
You can set the air supply to the individual vents with the air distribution
control ⇒page 103, fig. 99 . You can also set the vents 3 and 4
⇒ fig. 100 and 6 ⇒ fig. 101 individually.
Unwarmed or cooled air will flow out of the air outlet vents according to the
setting of control dial ⇒page 103, fig. 99 and the atmospheric condi-
tions.
The rear footwell vents 7 are controlled together with the vents 5. Turn the
air distribution control ⇒page 103, fig. 99 into the position
.
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 interior has been strongly heated through the effect of direct sunlight
in order to allow the heated air to escape.
The air conditioning 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 air conditioning 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 +5°C, there is a problem in the system. The reasons for this may be:
•The fuse of the air conditioning system is defective ⇒page 241.
Check the fuse, replace it if necessary.
•The cooling system has switched off automatically for a short time
because the coolant temperature of the engine is too hot.
If you are not able to rectify the operational problem yourself, or if the
cooling capacity decreases, switch the air conditioning system off. Please
contact your Škoda dealer.
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. It is not necessary to manually alter the settings. The
automatic
mode ⇒ page 109 ensures maximum wellbeing of the occupants at all
times of the year.
Description of Climatronic system
The Climatronic can only operate if the following conditions are met.
•engine running
•outside temperature above +5 °C,
•the button is not pressed.
If the Climatronic 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.
It is possible to briefly activate recirculated air mode in order to enhance
the cooling effect ⇒.
The heating effect is dependent upon the coolant temperature, thus full
heat output only occurs when the engine has reached its operating
temperature.
Puddle of water below car
After switching on the air conditioning 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!
Switching over from degrees Celsius to degrees Fahrenheit and vice
versa
First of all press and hold the button ⇒page 108, fig. 102 and
then press the button . The temperature measuring unit appears

Prewarming fuel
The vehicle is fitted with a fuel filter prewarming system. This secures
operation of a vehicle using diesel fuel down to an environmental temper-
ature of -25°C.
Biofuel
We recommend refuelling with diesel fuel at temperatures below -10°C.
Caution
It is not permitted to add the various fuel additives on the market, including
petrol, to diesel fuel in order to improve its flow properties.

– Place the cap onto the top of the fuel filler flap ⇒fig. 151.
Closing fuel filler cap
– Screw on the cap by turning it to the right until it is heard to lock.
– Press the fuel tank flap closed.
The correct grade of fuel for your vehicle as well as the tyre size and infla-
tion pressures are stated on a sticker affixed to the inside of the fuel filler
flap. Further information on fuel ⇒page 198.
The fuel tank has a capacity of about 62 litres.
Caution
•Remove any fuel which has spilled onto the paintwork of your vehicle
immediately. This particularly applies to biodiesel - risk of paint damage!Fig. 151 Filler flap with
cap unscrewed
WARNING
Pay attention to any legal requirements if you do carry a spare
canister in the vehicle. We do not recommend carrying any fuel
canisters in your vehicle for safety reasons. The canister can be
damaged in the event of an accident and fuel may leak out.

Inspecting and Replenishing203
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
The bonnet is held in the opened position by a pressurized gas spring.
Caution
•Never open the bonnet using the handle - danger of causing damage.
•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 en gine compartment
Particular care is required when carrying 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 and replenishing oil and
other fluids. For this reason, it is essential to comply with the
warning instructions st ated below and with the general applicable
rules of safety. The engine compartment 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 compartmen t - risk of scalding! 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 properly after closing the bonnet.
•Stop your vehicle immediately wh ile driving if you notice that
the lock is not properly engaged and close the bonnet properly -
risk of an accident!
WARNING
•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 gear-
shift 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.
•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 expansion 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.
•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-ribbed belt, alternator, radiator fan) and from the
high-voltage ignition system.
•Please also comply with the warning instructions stated below
when carrying out any essential work on the fuel system or on the
electrical system:
−Always separate the car battery from the electrical system.
− Do not smoke.
− Never carry out any work close to naked flames.

General comments
•New tyres do not offer optimal grip at first and should therefore be run
in for about 500 km at a moderate speed and an appropriately cautious
style of driving. You will also profit from longer tyre life.
•The tread depth of new tyres may differ because of design features
and the configuration of the tread (depending on the type of tyre and the
manufacturer).
•Drive over curbs on the side of the road and other such obstacles
slowly and, where possible, at a right angles in order to avoid damage to
tyres and wheel trims.
•Inspect your tyres from time to time for damage (punctures, cuts, splits
and bulges). Remove foreign bodies from the tyre profile.
•Damage to tyres and wheels is frequently not visible. Unusual vibra-
tions or pulling of the vehicle to one side could be a sign of tyre damage.
Please reduce your speed immediately and stop if you suspect that
a wheel is damaged. Inspect the tyres for signs of damage (bulges,
splits, etc.) If no visible damage is present, please drive at an appropri-
ately slow speed and carefully to the nearest Škoda dealer in order to
have your vehicle inspected.
•Also protect your tyres from contact with oil, grease and fuel.
•Immediately replace any dust caps of the valves which have got lost.
•Mark wheels before removing them so that their previous direction of
running can be maintained when mounted them again.
•Always store wheels or tyres which been removed in a cool, dry and,
where possible, dark place. Tyres which are not fixed to a wheel trim
should be stored upright. Please comply with any national regulations in other countries which may
differ from the information stated above.
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of the
tyre. This indicates the direction of rotation of the tyre, and it is essential
that the tyres are fitted on to run in this direction. Only then are the tyres
able to provide the optimal properties in terms of grip, low noise, wear-
and-tear and aquaplaning.
Further information concerning the use of unidirectional tyres
⇒
page 225.
Note
Please observe the various differing legal requirements regarding tyres.

Tyre life
The life of your tyres very much depends on the following points: Tyre inflation pressure
The working life of tyres will be shortened considerably if the tyres are
insufficiently or over-inflated and this will have an adverse effect on the
handling of your vehicle.
Check the inflation pressure of the tyres at least once a month. The tyre
inflation pressures for
summer tyres are indicated on the inside of the
fuel filler flap ⇒fig. 164 . The inflation pressures for winter tyres are 0.2
bar higher than those for summer tyres ⇒page 224.
Correctly inflated tyres are of particular importance when travelling at high
speeds. It is therefore good to check the pressure at least once a month
and also before setting off on a long trip. Please do not forget the spare
wheel when checking the tyres.
The tyre pressure should be at the highest pressure specified for your
vehicle at all times.
On cars with full wheel trim, valve extensions are fitted in place of dust
caps ⇒fig. 165 . It is not necessary to unscrew the valve extensions in
order to check and alter the inflation pressure of the tyre.
Driving style
Fast cornering, sharp acceleration and braking (squealing tyres) increase
wear-and-tear on your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influ-
ences when driving which may result in an imbalance and which makes
themselves felt through vibration in the steering.
You should have the wheels rebalanced since any imbalance increases
wear-and-tear on the steering, the suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted and each time a tyre is
repaired.

correct length and shape of spherical cap. This is essential to ensure that
the wheels are tightly fitted and that the brake system operates properly.
If you retrofit wheel trims (or have this done), please also ensure that an
adequate flow of air remains assured for cooling the brake system.
Škoda dealers are instructed in the technical possibilities which exist
regarding converting or retrofitting wheels, tyres and wheel trim.
The wheel bolts must be clean and must turn easily.
Winter tyres
The handling of your vehicle will be significantly improved when driving on
wintry roads and at temperatures below 7 °C if you fit winter tyres.
Summer tyres do not offer the same grip on ice and snow because of their
construction (width, rubber blend, tread pattern). This applies in particular
to vehicles which are equipped with low-profile tyres or high-speed
tyres (code index V, W or Y on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best
handling characteristics.
Only use radial winter tyres.
You must only fit those types of winter tyre which are approved for your
vehicle. The permissible sizes of winter tyres are stated in your vehicle
documents. Approvals may differ because of national legislation.
Please remember that the tyres should be inflated to 0.2 bar more than is
the case for summer tyres ⇒page 220.
Winter tyres no longer offer the same winter performance once the tyre
tread has worn down to a depth of about 4 mm.
Ageing also causes winter tyres to lose most of their winter performance
properties - even in cases where the remaining tread depth is still clearly
more than 4 mm. Speed restrictions
apply to winter tyres as well as to summer tyres
⇒ .
You can fit winter tyres of a lower speed category to your vehicle provided
that you also do not drive faster than the permissible maximum speed for
such tyres, even if the possible maximum speed of your vehicle is higher.
Exceeding the speed category of the tyre can lead to damage occurring.
Please pay attention to the notes if you decide to fit winter tyres
⇒ page 219.
You can also fit so-called “all-weather tyres” instead of winter tyres.
Please contact your Škoda dealer If there are any points which are not
clear who will be able to provide you with information regarding the
maximum speed fo r your tyres.
For the sake of the environment
Fit your summer tyres on again in good time since summer tyres offer you
better grip and handling on roads which are free of snow and ice - the
braking distance is shorter, there is less tyre noise, tyre wear is reduced
and fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.
WARNING
You must on no account drive your car at more than the permis-
sible maximum speed for your winter tyres - risk of an accident
resulting from tyre damage and loss of control over your car.
