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 85 or for Climatronic »
page 87.
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 201 .
› 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
80 Using the system

The engine is also preheated, if the auxiliary heating is switched on when the ve-
hicle is stationary and the engine is switched off.
The auxiliary heating (parking heating) warms up the coolant by combusting fuel
from the vehicle tank. The coolant warms up the air, which (if the blower speed is
not set to zero) flows into the passenger 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 de-
creased (e.g. with the vehicle parked in the sun). WARNING
■ The auxiliary heating must never be operated in closed rooms - risk of poi-
soning! ■ The auxiliary heating must not be running during refuelling - risk of fire.
■ The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore, if you wish to operate the auxiliary heating, do not park the
vehicle in such a way that the exhaust gases from the auxiliary heating can
come into contact with highly flammable materials (e.g. dry grass) or easily in-
flammable substances (e.g. spilt fuel). Note
■ If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
The auxiliary heating automatically controls the filling level in the fuel tank. If only
a low quantity of fuel is present in the fuel tank, the function of the auxiliary
heating is blocked. ■ 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 been operated several times over a
longer period, the vehicle must be driven a few kilometres 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 peri-
od. ■
The auxiliary heating and ventilation does not switch on or comes on, if the ve-
hicle battery indicates a low loading state » page 180, Automatic load deactiva-
tion .
■ The auxiliary heating (parking heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please re-
fuel! ■ 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 vehicle interior after switching on the auxili-
ary heating, you must maintain the comfort temperature normally selected by
you, leave the fan switched on and leave the air outlet vents in an open position.
It is recommended to put the air flow in the position  or .Ð Direct switching on/off

Heating and air conditioning system

The selector lever lock is only active if the vehicle is stationary or moving at speed
of less than 5 km/hour. The lock is switched off automatically into position N
when the car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the handle of selector lever prevents certain selector lever
positions being engaged inadvertently. The selector lever lock is cancelled when
the Shiftlock button is pressed.
Ignition key withdrawal lock
After the ignition is switched off, the ignition key can only be withdrawn if the se-
lector lever is in the position P. If the ignition key is withdrawn, the selector lever
is blocked in position P . ÐKickdown function
First read and observe the introductory information and safety warn-
ings on page 109.
The kickdown function provides you with maximum acceleration power.
When the accelerator pedal is fully depressed, the kickdown function is activated
in the desired driving program. This function has precedence over the driving pro-
gramme and serves for maximum acceleration of the vehicle when exploiting the
maximum power potential of the engine without taking into account the current
selector lever position ( D, S or Tiptronic ). The gearbox shifts down to one or sev-
eral gears in line with the driving state and the vehicle accelerates. The gearbox
does not shift up into the highest gear until the engine has reached its maximum
revolutions for this gear range. ÐDynamic shift programme
First read and observe the introductory information and safety warn-
ings on page 109.
The automatic gearbox of your vehicle is controlled electronically. Shifting up and
down through the gears is performed automatically on the basis of pre-defined
driving programmes.
Adopting a moderate style of driving
will cause the gearbox to select the most
economical driving programme. Shifting up into a higher gear as soon as possible
and shifting down as late as possible will have a favourable effect on your fuel
consumption. ä
ä When adopting a
sporty style of driving with rapid movements of the accelerator
pedal combined with sharp acceleration, frequent changes in speed and exploit-
ing the top speed of the car, the gearbox will adjust to this style of driving once
the accelerator pedal (kickdown function) is depressed and will shift down earlier,
frequently by several gears in comparison to a moderate style of driving.
Selecting the most appropriate driving programme for the particular style of driv-
ing is a continuous process. Irrespective of this it is, however, possible to switch
or shift down into a dynamic shift programme by depressing the accelerator rap-
idly. The gearbox shifts down into a lower gear in accordance with the speed,
therefore enabling rapid acceleration (e.g. when overtaking) without the accelera-
tor pedal having to be depressed into the kickdown range. The original pro-
gramme will be reactivated to match your particular style of driving once the
gearbox has shifted up again.
When driving in hilly regions, the gears are selected to match uphill and downhill
sections. This avoids the gearbox frequently shifting up and down when negoti-
ating an uphill stretch. When driving downhill, it is possible to shift down into the
Tiptronic position, in order to exploit the engine brake torque. Ð Emergency programme
First read and observe the introductory information and safety warn-
ings on page 109.
An emergency programme exists in the event of a fault in the system.
The gearbox operates in a corresponding emergency programme if there are
functional faults in the gearbox electronics. All of the display elements illuminate
or go out.
A functional fault can have the following effect:
› The gearbox only shifts into certain gears;
› The reverse gear
R cannot be used,
› The manual shift programme is switched off in emergency mode. Note
If the gearbox has switched to emergency mode, drive to a ŠKODA specialist ga-
rage to have the fault rectified. Ð

Driving Tips
Driving and the Environment
The first 1 500 km
New engine
The engine has to be run in during the first 1 500 kilometres.
Up to 1 000 kilometres › Do not drive faster than 3/4 of the maximum speed of the gear in use, i.e. 3/4 of
the maximum permissible engine speed.
› No full throttle.
› Avoid high engine speeds.
› Do not tow a trailer.
From 1 000 up to 1
500 kilometres
› Gradually
increase the power output of the engine up to the full speed of the
gear engaged, i.e. up to the maximum permissible engine speed.
During the first operating hours the engine has higher internal friction than later
until all of the moving parts have harmonized. The driving style which you adopt
during the first approx.1

500 kilometres plays a decisive part in the success of
running in your car.
Never drive at unnecessarily high engine speeds even after the running-in period
is complete. The maximum permissible engine speed is marked by the start of the
red scale area of the revolutions counter. On vehicles fitted with a manual gear-
box, at the very latest shift up into the next gear when the red area is reached.
During acceleration (depressing the accelerator) exceptionally high engine
speeds are automatically reduced, yet the engine is not protected against too
high engine speeds which are caused by incorrectly shifting down the gears re-
sulting in a sudden increase of the engine speeds above the permitted maximum
revolutions which can lead to engine damage.
For a vehicle fitted with a manual gearbox the converse situation also applies: Do
not drive at an engine speed that is too low. Shift down a gear when the engine
is no longer running smoothly. Observe the recommended gear » page 11, Recom-
mended gear . CAUTION
All the speed and engine revolution figures apply only when the engine is at its
normal operating temperature. Never rev up a cold engine when the vehicle is
stationary or when driving in individual gears. For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a higher gear
as early as possible are ways to minimise fuel consumption and operating noise
levels and protects the environment. Ð New tyres
New tyres have to be “
run in” since they do not offer optimal grip at first. Drive
especially carefully for the first 500 km or so. Ð New brake pads
New brake pads initially do not provide full braking efficiency. The brake pads
must initially be “run in

”. Drive especially carefully for the first 200 km or so. Ð Catalytic converter
Proper operation of the emission control system (catalytic converter) is of major
significance for driving your vehicle in an environmentally conscious way.
The following guidelines must be observed: › Vehicles fitted with a petrol engine must always be refueled with unleaded pet-
rol » page 168 , Unleaded petrol ;
› Do not pour too much oil into the engine
» page 172, Checking the engine oil
level ;
› Do not switch off the ignition while driving.
If you drive your vehicle in a country in which unleaded petrol is not available, you
must have the catalytic converter replaced later when driving the vehicle into a
country in which use of a catalytic converter is mandatory. £
146 Driving Tips

WARNING
■ In view of the high temperatures which can be produced in the catalytic con-
verter, the vehicle should be parked in such a way that the catalytic converter
cannot come into contact with easily flammable materials under the vehicle -
risk of fire!
■ Never use additional underbody protection or anti-corrosion agents for ex-
haust pipes, catalytic converters or heat shields - risk of fire! CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of fuel
can cause misfiring, which can result in considerable damage to parts of the en-
gine and exhaust system. ■ Just filling the tank with leaded petrol once will damage the exhaust system! ÐEconomical and environmentally friendly driving
Introductory information
Your fuel consumption, any pollution of the environmental and the wear-and-tear
to the engine, brakes and tyres, depend essentially on three factors:
› your personal style of driving;
› the conditions under which your vehicle is operated;
› technical aspects.
The fuel economy by can be improved by 10
-15 % by always looking ahead and
driving in an economical way.
Fuel consumption is also be influenced by external factors which are beyond the
driver's control. Consumption increases during the winter or under difficult condi-
tions, on poor roads, etc.
Fuel consumption can vary considerably from the manufacturer's data, as a result
of outside temperatures, the weather and driving style.
The technical requirements for low fuel usage and economic efficiency of the ve-
hicle have already been built into the vehicle at the works. ŠKODA places a partic-
ular emphasis on minimising negative effects on the environment. It is necessary
to take note of the guidelines given in this chapter in order to make best use of
these characteristics and to maintain their effectiveness. The optimal engine speed should be obtained when accelerating, in order to
avoid a high fuel consumption and resonance of the vehicle.
Ð Looking ahead when driving
A vehicle's highest fuel consumption occurs when accelerating, therefore unnec-
essary accelerating and braking should be avoided. If looking ahead when driving,
less braking and consequently less accelerating are required. If possible, let your
vehicle coast to a stop, or use the engine brake, if you can see that the next set
of traffic lights is on red, for example. Ð Shifting to save energy
Fig. 131
Principle sketch: Fuel consump-
tion in litres/100 km depending
on the selected gear
Shifting up early saves on fuel.
Manual gearbox › Drive no more than about one length of your vehicle in first gear.
› Shift up into the next gear at approx. 2

000 revolutions.
An effective way of achieving good fuel economy is to shift up early. Observe the
recommended gear » page 11, Recommended gear .
A suitably selected gear can have an effect on fuel consumption » Fig. 131.
Automatic gearbox › Slowly
apply the accelerator pedal. However, do not depress it to the kickdown
position.
› If the accelerator pedal is only depressed slowly on a vehicle fitted with an au-
tomatic gearbox, an economic driving programme is automatically selected.

Driving and the Environment

Note
Observe the recommended gear » page 11, Recommended gear .ÐAvoiding full throttle
Fig. 132
Principle sketch: Fuel consump-
tion in litres/100 km. and speed
in km/h.
Driving more slowly means saving fuel.
Sensitive use of the accelerator will not only significantly reduce fuel consump-
tion but also positively influence environmental pollution and wear of your vehi-
cle.
The maximum speed of your vehicle should, as far possible, never be used. Fuel
consumption, pollutant emissions and vehicle noises increase disproportionally at
high speeds.
The » Fig. 132 shows the ratio of fuel consumption to the speed of your vehicle.
Fuel consumption will be halved if only three-quarters of the possible top speed
of your vehicle is used. ÐReducing idling
Idling also costs fuel.
In vehicles not equipped with the
START-STOP system, turn off the engine when
in a traffic jam, at a level crossing or traffic lights with longer wait times. Even af-
ter just 30 - 40 seconds you will have saved more fuel than that is needed when
you start the engine up again. If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant emissions, though, are particularly
high in the warming-up phase. Therefore, start driving as soon as the engine has
started, whereby high engine speeds should be avoided. Ð Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
By having your vehicle regularly maintained by a ŠKODA

specialist garage, you
create the conditions needed for driving economically. The maintenance state of
your vehicle has a positive effect on traffic safety and value retention
A poorly tuned engine can result in a fuel consumption which is 10 % higher than
normal.
Also check the oil level when refuelling. Oil consumption is dependent to a con-
siderable extent on the load and speed of the engine. Oil consumption could be
as high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine has a higher oil consumption at first, and rea-
ches its lowest level only after a certain running in time. The oil consumption of a
new vehicle can therefore only be correctly assessed after driving about
5 000 km. For the sake of the environment
■ Additional improvements to the fuel economy can be made by using synthetic
high-lubricity oils.
■ Regularly check the ground under the vehicle. Have your vehicle inspected by a
ŠKODA specialist garage if you find any stains caused by oil or other fluids on the
floor. Note
We recommend that your vehicle is serviced on a regular basis by a ŠKODA Serv-
ice Partner. Ð
148 Driving Tips

Avoid short distances
Fig. 133
Principle sketch: Fuel consump-
tion in l/100 km at different tem-
peratures
Short distances result in an above-average high fuel consumption. We therefore
recommend avoiding distances of less than 4 km if the engine is cold.
A cold engine consumes the most fuel immediately after the start. Fuel consump-
tion drops to 10 litres/100 km after just 1 kilometre. The consumption stabilises
once the engine and catalytic converter have reached their operating tempera-
ture.
An important factor in this connection is also the ambient temperature. The im-
age » Fig. 133 shows the different levels of fuel consumption after driving a cer-
tain distance at a temperature of +20 °C and a temperature of -10 °C. Your vehicle
has a higher fuel consumption in the winter than in the summer. ÐChecking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure the tyre inflation pressure is correct. The rolling resistance will be
increased if the tyre filling pressure is too low. This will not only increase fuel con-
sumption but also tyre wear and the driving behaviour will worsen.
Always check the tyre inflation pressure when the tyres are cold. ÐAvoid unnecessary ballast
Transporting ballast costs fuel.
Each kilogramme of weight increases the fuel consumption. It is worth checking
the boot to avoid transporting any unnecessary ballast. It is particularly in town traffic, when one is accelerating quite often, that the ve-
hicle 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 consumption of about 1 litre/100 kilometres.
At a speed of 100 - 120 km/h, your vehicle that is fitted with a roof rack cross
member without a load will use use about 10 % more fuel than normal due to the
increased aerodynamic drag.
Ð Saving electricity
When the engine is running, the alternator generates and supplies electrical pow-
er. If more electrical components of the electrical system are switched on, more
fuel is needed to operate the alternator. We therefore recommend switching off
electrical components if these are no longer required. Ð Environmental compatibility
Environmental protection has played a major role in the design, selection of mate-
rials and manufacture of your new

ŠKODA. Particular emphasis has been placed
on the following points:
Design measures
› Joints designed to be easily detached.
› Simplified disassembly due to the modular structure system.
› Improved purity of different 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 recyclable material.
› Air conditioning filled with CFC-free refrigerant.
› No cadmium.
› No asbestos.
› Reduction in the “vaporisation” of plastics.
Manufacture › Solvent-free cavity protection.
› Solvent-free protection of the vehicle for transportation from the production
plant to the customer. £

First read and observe the introductory information and safety warn-
ings on page 151.
Important information
› The first priority should always be
safety.
› Do not drive off-road if your vehicle is not suited to it. Your vehicle is not de-
signed for expedition-like travel.
› Before every off-road journey, make sure that the vehicle is appropriately
equipped for the planned journey.
› Check the tyre inflation pressure on your vehicle and adjust where necessary.
› Fill up. The fuel consumption of the vehicle is much higher when driving off-
road than when driving on the road.
› Pay attention to possible hazards before driving on unfamiliar territory.
› Before driving, always put the seat belt on correctly. Make sure that your front
passenger and your passengers seated on the rear seats always fasten their
seat belts correctly.
› You must be seated in such a way that you have good front visibility, especially
when driving uphill or downhill. You must never be seated in such a way that
the distance between your chest and the middle of the airbag cover is less than
25 cm » page 138, Front airbags.
› Use a suitable pair of shoes which makes it safer to operate the pedals.
› Install the towing eye at the front or at the rear before driving off-road. It is not
always possible to install the towing eye if the vehicle got stuck.
› Check the car tool kit, stock up where necessary.
› Fill the engine oil up to the mark A
» page 172
, Checking the engine oil level .
› Fill up the windscreen washer fluid.
› Your vehicle has a higher centre of gravity than normal cars. This increases the
risk of vehicle rollover when driving on-road and off-road.
› Secure the items in your vehicle properly. Ð
