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 e.g. ice, snow or leaves to ensure 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 not a leak!
WARNINGFor 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 cor-
rectly operate the heating and ventilation systems, how to demist and defrost
the windows, as well as with the cooling mode.
Note
■ The used air streams out through the vents in the luggage compartment.■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).

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.
For the sake of the environment
Pollutant emissions are also reduced when fuel is saved » page 101, Economical
and environmentally friendly driving .
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 200 .
› 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 resolve the operational fault yourself, or if the cooler output has reduced, switch off the cooling system and get assistance from a ŠKODA Spe- cialist garage.

81Heating and air conditioning system

›The engine is also preheated when the vehicle is stationary and the engine is
not running;
› It warms up the coolant by burning 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 can come into contact with high-
ly flammable materials (e.g. dry grass) or easily inflammable substances (e.g.
spilt fuel).
CAUTION
■ The running auxiliary heater consumes fuel from the vehicle tank and automati-
cally controls the filling level. 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.
Note
■ 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.
■
The air inlet in front of the windscreen must be free of e.g. ice, snow or leaves
to ensure that the auxiliary heating and cooling system operates properly.

Explanation of graphicAAerialBBattery coverCWarning lightSwitch on the auxiliary heatingSwitch off the auxiliary heating
The transmitter and the battery are housed in the housing of the remote control.
The receiver is located in the interior of the vehicle.
When the battery is fully charged, the range of the remote control is a few hun-
dred metres. Obstacles between the radio remote control and the vehicle, bad
weather conditions and a weaker battery can clearly reduce the range.
To switch the auxiliary heating on or off, hold the remote control vertical, with the
aerial pointing upwards. The antenna must not be covered with the fingers or the palm of the hand during this process.
The auxiliary heating can only be switched on/off safely using the radio remote control, if the distance between the radio remote control and the vehicle is at
least 2 m.
After pressing the button, the warning light in the remote control gives the
user different kinds of feedback:

WARNING■
Never adjust the steering wheel when the vehicle is moving only when the
vehicle is stationary!■
Maintain a distance of 25 cm
1
to the steering wheel » Fig. 89 on page 93
–  . Not maintaining this minimum distance will mean that the airbag system
will not be able to properly protect you – hazard!
■
The lever for adjusting the steering wheel must be locked whilst driving so
that the position of the steering wheel cannot accidently change during the journey – risk of accident!
■
If the steering wheel is adjusted further towards the head, the protection
provided by the driver airbag in the event of an accident is reduced. Check
that the steering wheel is aligned to the chest.
■
When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock position. Never hold the steering wheel in
the 12 o'clock position or in any other way (e.g. in the middle or inner edge of the steering wheel). In such cases, you could injure the arms, hands and head
when the driver airbag is deployed.
WARNING (Continued)■ When driving, the ignition key must always be in the position 2 » Fig. 90 on
page 94 (ignition switched on) without the engine running. This position is
indicated by the warning lights coming on. If this is not the case, it could result
in unexpected locking of the steering wheel – risk of accident!■
Only pull the ignition key from the ignition lock when the vehicle has come
to a complete stop (by applying the handbrake). Otherwise the steering wheel
could block – risk of accident!
■
When leaving the vehicle, the ignition must always be removed. This is par-
ticularly important if children are left in the vehicle. Otherwise the children
could, for example, start the engine – risk of accident or injury!
■
Never leave the engine running in unventilated or closed rooms. The ex-
haust gases of the engine contain besides the odorless and colourless carbon
monoxide a poisonous gas – hazard! Carbon monoxide can cause uncon-
sciousness and death.
■
Never leave the vehicle unattended with the engine running.
■
Never switch off the engine before the vehicle is stationary – risk of acci-
dent!
CAUTION
■ The starter may only be operated (ignition key position 3 » Fig. 90 on
page 94), if the engine is not running. The starter or engine can be damaged if
the starter is activated when the engine is running.■
Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its operating temperature – risk of damaging the en-
gine!
■
Do not tow start the engine - danger of damaging the engine! On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage the catalytic converter. The battery from an- other vehicle can be used as a jump-start aid » page 195.
■
Do not switch the engine off immediately at the end of your journey after the
engine has been operated over a prolonged period at high loads but leave it to
run at an idling speed for about 1 minute. This prevents any possible accumulation of heat when the engine is switched off.
For the sake of the environment
Do not warm up the engine while the vehicle is stationary. If possible, start your
journey as soon as the engine has started. Through this the engine reaches its
operating temperature more rapidly and the pollutant emissions are lower. 92Using the system

Note■The engine can only be started with a genuine ŠKODA key with the matching
code.■
The engine running noises may louder at first be louder for a short time after
starting the cold engine. This is quite normal and is not an operating problem.
■
After switching off the ignition, the radiator fan can intermittently continue to
operate for approx. 10 minutes.
■
If the engine also does not start after the second attempt, the fuse for the elec-
tric fuel pump (in petrol engines) or the control unit for the glow plug system or
glow plug system relay and fuel pump (in diesel engines) could be faulty. Check
the fuse and replace, if necessary » page 199 or seek assistance from a ŠKODA
specialist garage.
■
We recommend locking the steering wheel whenever leaving the vehicle. This
acts as a deterrent against the attempted theft of your car.

Power steering
First read and observe the introductory information and safety warn-ings
on page 92.
The power steering enables you to steer the vehicle with less physical force.
It is still possible to fully steer the vehicle if the power steering fails or if the en- gine is not running (vehicle being towed in). However, greater physical effort is
required to turn the steering wheel.
Steering force assistance can be influenced by the selection of driving
mode » page 124 .

Electronic immobiliser
First read and observe the introductory information and safety warn-
ings
on page 92.
An electronic chip is integrated in the head of the key. The immobiliser is deacti-
vated with the aid of this chip when the key is inserted in the ignition lock. The
electronic immobiliser is automatically activated when the ignition key is with-
drawn from the lock.
The engine will not start if a non-authorized ignition key is used.

Driving and the Environment
Running in
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 lateruntil 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 gearbox, at the very latest shift up into the nextgear when the red area is reached. Very high engine speeds when accelerating
(accelerator) are automatically restricted »
.
If the engine is no longer running smoothly, do not drive with unnecessarily low
engine revs on a vehicle with manual transmission. Shift down. Observe the rec-
ommended gear » page 21.
CAUTION■
The engine is not protected from excessive engine revs caused by shifting
down at the wrong time. This can result in the sudden increase in revs beyond
the permissible maximum rpm and thus cause engine damage.■
Never rev up a cold engine when the vehicle is stationary or when driving in in-
dividual gears.
■
All the speed and engine revolution figures apply only when the engine is at its
normal operating temperature.
For the sake of the environment
Never drive with unnecessarily high engine revs. Shifting up sooner helps save on
fuel, reduces engine noises and protects the environment.
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.

New brake pads
New brake pads initially do not provide optimal braking performance. They first need to be “run in”. Drive especially carefully for the first 200 km or so.

Catalytic converter
Proper operation of the emission control system (catalytic converter) is of major
significance for driving your vehicle in an environmentally conscious way.
› Vehicles fitted with a petrol engine must always be refuelled with unleaded
petrol » page 168 .
› Do not pour too much oil into the engine
» page 172, Checking the engine oil
level .
› Do not switch off the ignition while you are driving the vehicle.
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. 
100Using the system

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!

Economical and environmentally friendly driving
Introductory information
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.
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 optimal engine speed should be obtained when accelerating, in order to
avoid a high fuel consumption and resonance of the vehicle.
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.

Shifting to save energy
Fig. 95
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 21.
A suitably selected gear can have an effect on fuel consumption » Fig. 95.
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.
