The Climatronic in automatic mode ensures the best-possible setting of the
temperature of the outflowing air, 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 110.
The engine is running.
The outside temperature is above approx. +2 °C.
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 sollar cells, the fresh air
blower is automatically switched over to “solar mode” if the sun ray's 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. 122 on page 108 .
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.
■
On vehicles equipped with a factory-fitted radio or radio navigation system,
the Climatronic information is also shown on their displays. This function can
be switched off, see » operating instructions for the radio or navigation sys-
tem .

Auxiliary heating (auxiliary heating and ventilation)
 Introduction
This chapter contains information on the following subjects:
Switching on/off
117
Radio remote control
118
Conditions for the functioning of auxiliary heating (Aux. heating and ventila-
tion), hereinafter referred to only as auxiliary heating (Aux. heating).
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).
Auxiliary heating (aux. heating)
The auxiliary heating (aux. heating) can be used when stationary, when the
engine is switched off to preheat the vehicle and while driving (e.g. during the
heating phase of the engine).
The auxiliary heating (auxiliary heating) functions in connection with the air-
conditioning system or Climatronic.
The auxiliary heating (aux. heating) also warms up the engine. This is not valid
for vehicles with the 3.6 l/191 kW FSI engine.
The auxiliary heating (parking heating) warms up the coolant by combusting
fuel from the vehicle tank. The coolant heats air flowing into the passenger
compartment (as long as the blower fan speed
B
» Fig. 124 on page 110
or » Fig. 125 on page 113 is not set to zero). 
116Operation

WARNING■The auxiliary heating (aux. heating) must never be operated in closed
rooms (e.g. garages) – risk of poisoning!■
The auxiliary heating (aux. heating) must not be allowed to run during re-
fuelling – risk of fire.
■
The exhaust pipe of the auxiliary heating (aux. heating) is located on the
underside of the vehicle. Therefore, if you wish to operate the auxiliary
heating (aux. heating), do not park the vehicle in such a way that the ex-
haust gases can come into contact with highly flammable materials (e.g. dry
grass) or easily inflammable substances (e.g. spilt fuel) – risk of fire.
CAUTION
■ Running auxiliary heating (aux. heating) consumes fuel from the vehicle tank
and automatically controls the filling level. If only a low quantity of fuel is
present in the fuel tank, the auxiliary heating (aux. heating) switches off.■
The exhaust pipe of the auxiliary heating (aux. 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 (aux. heating) is running, the vehicle battery discharg-
es. 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 (aux. heating) switches on the blower B » Fig. 124 on
page 110 or » Fig. 125 on page 113 only 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 operat-
ing problem.
■
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating (aux. heating) operates properly.
■
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 
.

Safety eyelet
The purpose of the safety eyelet
B
» Fig. 158 is to attach the breakaway cable
of the trailer.
When attaching the breakaway cable to the safety eyelet, it must sag freely
against the vehicle in all trailer positions (sharp bends, in reverse etc.).
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see
the traffic behind the trailer with the standard rear-view mirrors. The national
legal requirements must be observed.
Headlights
The front of the vehicle may lift up when a trailer is being towed and the head-
lights may dazzle other road users.
Adjust the headlights using the headlight beam control » page 66, Parking and
low beam lights .
Driving speed
For safety reasons, do not drive faster than 80 km/h when towing a trailer.
Immediately reduce your speed as soon as even the slightest swaying of the
trailer is detected. Never attempt to stop the trailer from “swaying” by acceler-
ating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply
the brakes gently at first, then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as
a brake.
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 indicator light  in the instrument cluster
lights up. Wait a few minutes and check the level of coolant » page 188,
Checking the coolant level .
The following guidelines must be observed » page 34,
 Coolant
.
The coolant temperature can be reduced by switching on the heating.WARNING■ Never use the safety eyelet for towing!■Adapt your speed to the conditions of the road surface and to the traffic
situation.■
Improper or incorrectly connected electric cables can energise the trailer
and cause functional faults to the vehicle's entire electrical system as well
as accidents and severe injuries.
■
Work on the electrical system must only be carried out by specialist ga-
rages.
■
Never directly connect the trailer's electrical system with the electrical
connections for the tail lights or other current sources. 
167Towing a trailer

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 by mistake do not start the engine or
switch on the ignition! Extensive damage to engine parts can occur! We rec-
ommend that you have the fuel system cleaned by a specialist garage.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with bio fuel 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!

Read and observe and on page 182 first.
The windscreen washer fluid reservoir is located in the engine compart-
ment » Fig. 162 .
This contains the cleaning fluid for the windscreen or rear window and for the
headlight cleaning 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.
In Winter, the washing water should always be mixed with antifreeze 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. 164 on page 188 .WARNING■
The 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 182.■
Do not continue your journey if for some reason it is not possible to fill
with coolant under the current circumstances 
. Switch off the engine and
seek assistance from a specialist garage.
CAUTION
■ 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. 164 on page 188 .
■
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.

» Fig. 164 .
If the coolant level in the coolant expansion tank is too low, this is indicated by
the warning light  lighting up in the instrument cluster
» page 34,
 Coolant
.
We still recommend inspecting the coolant level directly at the reservoir from
time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a specialist
garage.
Replenishing
Read and observe
and on page 187 first.
Only top up with new coolant.
›
Switch off the engine.
›
Allow the engine to cool.
›
Place a cloth over the cap of the coolant expansion tank and unscrew the
cap carefully .
›
Replenish the coolant.
›
Turn the cap until it clicks into place.
Do not use an alternative additive if the specified coolant is not available in an
emergency. In this case, use just water and have the correct mixing ratio of
water and coolant additive restored by a specialist garage as soon as possible.
