Cold range
The pointer in the left of the scale indicates that the engine has not yet
reached its operating temperature. Avoid high speeds, full throttle and high
engine loads. This prevents possible damage to the engine.
The operating range
The engine has reached its operating temperature as soon as the pointer
moves into the middle of the scale. At very high ambient temperatures or un-
der heavy engine loads, the pointer may move even further to the right.
High temperature range
The coolant temperature is too high if the pointer reaches the red area of the
scale. Further information » page 36.

Air conditioning system
Heating, ventilation, cooling
Introduction
This chapter contains information on the following subjects:
Air outlets
110
Using the air conditioning system economically
111
Operational problems
112
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 cooling system prevents the windows from misting up during
winter months.
It is possible to briefly activate recirculated air mode to enhance the cooling
effect.
Please refer to the information regarding recirculated air mode for the air con-
ditioning system » page 114 or for Climatronic » page 117.
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 de-
mist and defrost the windows, as well as with the cooling mode.■
To reduce health risks (e.g. common colds), the following instructions for
the use of the cooling system are to be observed. ■The difference between the indoor temperature and the outdoor air
temperature should not be greater than about 5 ° C.
■ The cooling system is to be turned off about 10 minutes before the end
of the journey.
■ Once a year, a disinfection of the air conditioner or the Climatronic is to
be carried out by a specialist company.
CAUTION■ The air inlet in front of the windscreen must be free (e.g. of 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
conditioning may drip down and form a puddle below the vehicle. This is not a
leak.
Note
■ The exhaust air streams out through vents at the rear of the luggage com-
partment.■
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 interior of the vehicle forms deposits in the evaporator of the air condition-
ing system. This produces a permanent odour when the air conditioning sys-
tem is operating which can only be eliminated through considerable effort and
expense (replacement of compressor).

Operational problemsRead and observe
and on page 110 first.
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 220 .
› The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot » page 31.
If you are not able to resolve the operational problem yourself, or if the cooler
output has reduced, switch off the cooling system and seek assistance from a
specialist garage.

The cooling system operates only if the following conditions are met. The cooling system is switched on » page 112.
The engine is running.
The outside temperature is above approximately +2 °C.
The blower is switched on.
Under certain circumstances, air at a temperature of about 5 °C can flow out of
the vents when the cooling system is switched on.
If the desired interior temperature can also be achieved without activating the
cooling system, fresh air mode should be selected.
The cooling system is switched off at a high coolant temperature in order to
provide cooling at a high load of the engine.
CAUTION
Lengthy and uneven distribution of the air flow out of the vents (especially
around the feet) and large differences in temperature, for example, when get-
ting out of the vehicle, can cause susceptible individuals to catch a cold.Note■ We recommend that you have the air conditioning system cleaned by a spe-
cialist garage once every year.■
During operation of the air conditioning, an increase in engine idle speed may
occur under certain circumstances in order to ensure sufficient heating com-
fort.

The Climatronic in automatic mode ensures the best possible setting for the
temperature of the air flowing out, the blower stage and air distribution.
The system also takes sunlight into account, which eliminates the need to al-
ter the settings manually.
The cooling system operates only if the following conditions are met. The cooling system is switched on » page 112.
The engine is running.
The outside temperature is above approximately +2 °C.
The blower is switched on.
The cooling system is switched off at a high coolant temperature in order to
provide cooling at a high load of the engine.
Aeration of the vehicle when ignition is switched off
On models fitted with power sliding/tilting roof with solar cells, the fresh air
blower is automatically switched over to “solar mode” if the sun rays are suffi- cient after switching off the ignition. The solar cells on the sliding/tilting roof
deliver power for the fresh air blower. This supplies the interior of the car with
fresh air.
For an optimum ventilation, the air outlet vents 2 and 3 must be
opened » Fig. 123 on page 110 .
The ventilation functions only when the sliding/tilting roof is fully closed.

Auxiliary heating (auxiliary heating and ventilation)
 Introduction
This chapter contains information on the following subjects:
Switching on/off
119
Radio remote control
120
Functional requirements of the auxiliary heating (auxiliary heating and ventila-
tion)
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning icon  is not lit in the display of
the instrument cluster).
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).
Additional heating (hereinafter only as a aux. heating)
The auxiliary heating can be used when both when stationary, when the en-
gine is switched off, to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The aux. heating functions in connection with the air conditioning system or
Climatronic.
The auxiliary heating also warms up the engine. This is not valid for vehicles
with the 3.6 l/191 kW FSI engine.
The auxiliary heating warms up the coolant by combusting fuel from the vehi-
cle tank. This warms the air flowing into the passenger compartment (if the
blower is turned on).
Depending on the environmental conditions, the automatic on or off of the
heater occurs, which causes the best possible conditions for the engine run-
ning and the interior heating.
For vehicles with petrol engines, the automatic switching on and off of the
heater can be disabled at a specialist workshop. 
118Operation

WARNING■The auxiliary heating must never be operated in closed rooms (e.g. garag-
es) – risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the heater, then the car should not be
parked in places where the exhaust gases can come into contact with flam- mable materials such as dry grass, undergrowth, leaves, spilled fuel or simi-
lar - Risk of fire.
CAUTION
■ The running auxiliary heater consumes fuel from the vehicle tank and auto-
matically controls the filling level. If only a low quantity of fuel is present in the
fuel tank, the auxiliary heating switches off.■
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 is running, the vehicle battery discharges. If the auxili-
ary heating and ventilation has been operated several times over a longer peri-
od, the vehicle must be driven a few kilometres in order to recharge the vehi-
cle battery.
■
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly.
Note
■ The auxiliary heating switches on the blower B » Fig. 125 on page 112
or » Fig. 126 on page 115 only if it has achieved a coolant temperature of ap-
prox. 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 operat-
ing problem.
■
So that warm air can flow into the vehicle interior after switching on the aux-
iliary 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 po-
sition. It is recommended to put the air flow in the position 
or 
.

The following guidelines must be observed » page 36, 
Coolant .
The coolant temperature can be reduced by switching on the heating.WARNING■ Always drive particularly carefully with the trailer.■Adapt your speed to the conditions of the road surface and to the traffic
situation.
CAUTION
If you tow a trailer frequently, you should also have your vehicle inspected be-
tween service intervals.
Trailer stabilisation (TSA)
The trailer stabilisation is an extension of the stabilisation control that works
in conjunction with the counter-steering assistance to reduce the amount the
trailer "sways".
After turning on the ignition, the ESC warning light 
in the instrument cluster
illuminates for about 2 seconds longer than the ABS warning light.
Function requirements for trailer stabilisation. The trailer was shipped from the factory or purchased from the ŠKODA
genuine accessories.
The ESC is active. (Warning lights 
or 
do not illuminate in the instru-
ment cluster).
The trailer is electrically connected to the towing vehicle by means of the
trailer socket.
The speed is higher than approx. 60 km/h.
The trailer has a rigid drawbar.
WARNING■ The increased safety offered by the trailer stabilisation must not tempt
you to take greater risks than otherwise.■
Avoid abrupt and sudden driving and braking manoeuvres - there is a risk
of accidents.
CAUTION
■ The trailer stabilisation need not be able to correctly detect all of driving sit-
uations.■
Light trailers that sway are not always detected and therefore stabilised ac-
cordingly by the trailer stabilisation.
■
Release the pressure on the accelerator pedal if the system is being regula-
ted.
Note
The trailer stabilisation works for both braked and unbraked trailers.
Anti-theft alarm system
When the vehicle is locked, the alarm is activated when the electrical connec-
tion to the trailer is interrupted.
Always switch off the anti-theft alarm system before a trailer is coupled or un-
coupled » page 55 .
Conditions for including a trailer in the anti-theft alarm system. The vehicle is factory fitted with an anti-theft alarm system and towing
equipment.
The trailer is electrically connected to the towing vehicle by means of the
trailer socket.
The electrical system of the vehicle and trailer is functional.
The vehicle is locked with the vehicle key and the anti-theft alarm system
is activated.

Clear water is not sufficient to intensively clean the windscreen and head-
lights. We recommend using clean water together with a screen cleaner from
the range of ŠKODA Original Accessories (with antifreeze in winter), which will
remove any stubborn dirt.
The washing water should always be mixed with antifreeze in winter even if
the vehicle has heated windscreen washer nozzles.
Under exceptional circumstances, methylated spirits can also be used if no
screen cleaner with antifreeze is available. The concentration of methylated
spirits must not be more than 15 %. The freeze protection at this concentration
is sufficient only to -5 °C. 
