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.
Note■ We recommend that you have Climatronic cleaned by a specialist garage
once every year.■
During operation of the Climatronic, an increase in engine idle speed can oc-
cur under certain circumstances in order to ensure adequate heating comfort.

Auxiliary heating (auxiliary heating and ventilation)
 Introduction
This chapter contains information on the following subjects:
Switching on/off

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 
.

Engine overheating
The speed must be reduced immediately if the needle for the coolant tempera-
ture gauge moves into the right-hand area or the red area of the scale.
Stop and switch off the engine if the warning light 
in the instrument cluster
illuminates.
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.
CAUTION
For technical reasons, trailers with rear LED lights cannot be connected to the
anti-theft alarm system.172Driving

CAUTION■Just filling the tank once with diesel fuel that does not comply with the
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system!■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is used, do not start the engine or switch on the
ignition! Engine parts could be significantly damaged!
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with biofuel RME, therefore this fuel must
not be filled in the tank and used for driving the vehicle. The use of biofuel
RME can cause considerable damage to parts of the engine or fuel system.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents), into the diesel. This can result in considerable damage to parts of the
engine or the exhaust system!

The capacity of the reservoir is about 3 litres or about 5.5 litres on vehicles that
have a headlight cleaning system 1)
.
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. 

The coolant consists of water with coolant additive. This mixture guarantees
antifreeze protection, protects the cooling/heater system against corrosion
and prevents lime formation.
Vehicles exported to countries with a mild climate are already factory-filled
with a coolant which offers antifreeze protection down to about -25 ℃. In
these countries, the concentration of coolant additive should be at least 40%.
Vehicles exported to countries with a cold climate are already factory-filled
with a coolant which offers antifreeze protection down to about -35 °C. In
these countries, the concentration of coolant additive should be at least 50%.
If a higher concentration of antifreeze is required for climatic reasons, the con-
centration of coolant additive can be increased up to a maximum of 60% (anti-
freeze protection down to approx. -40 °C).
When refilling, only use the same antifreeze identified on the coolant expan-
sion vessel » Fig. 167 on page 192 .
WARNINGThe engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en- gine compartment » page 186.
CAUTION
■
 Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
ventilate - there is a risk of engine damage, 
do not continue driving! Switch
off the engine and seek assistance from a specialist garage.
■
The concentration of coolant additive in the coolant must never be under
40%.
■
Over 60% of coolant additive in the coolant reduces the antifreeze protec-
tion and cooling effect.
■
A coolant additive that does not comply with the correct specifications can
significantly reduce the corrosion protection.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 167 on page 192 .
■
If a fault causes the engine to overheat, we recommend visiting a specialist
garage, as otherwise serious engine damage may occur.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
