Coolant temperature/coolant level 
If the warning light 
lights up, this means the coolant temperature is too high.
The following message is shown in the information cluster display:
Check coolant! Owner's manual!
or ENGINE COOLANT PLEASE CHECK
Stop the vehicle, switch off the engine, check the level of the coolant » page 174,
and refill the coolant if necessary » page 175.
If the coolant is within the specified range, the increased temperature may be
caused by an operating problem at the radiator fan. Check the fuse for the radia-
tor fan, replace if necessary » page 201, Fuses in the engine compartment .
Do not continue driving if the warning light   does not go off even though the
coolant level is correct and the fuse for the fan is in working order!

tance from the traffic, switch off the engine and activate the hazard warning
light system » page 49.■
Carefully open the coolant expansion bottle. If the engine is hot, the cooling
system is pressurized – risk of scalding! It is therefore best to allow the engine
to cool down before removing the cap.
■
Do not touch the radiator fan. The radiator fan may switch itself on auto-
matically even if the ignition is off.

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.

If your vehicle has already been factory-fitted with a towing device or is fitted
with a towing device from ŠKODA Original Accessories, then it meets all of the
technical requirements and national legal provisions for towing a trailer.
Your vehicle is fitted with a 13-pin power socket for the electrical connection be-tween the vehicle and trailer. If the trailer that is to be towed has a 7-pin connec-
tor , you can use a suitable adapter from ŠKODA Original Accessories.
The maximum trailer drawbar load is 75 kg/h.
WARNING■
Before each time you make a journey when using the ball rod, check that it
is seated correctly and is secured in the mounting recess.■
Do not operate the ball rod if it is not correctly inserted in the mounting re-
cess.
■
Do not operate the towing device if it is damaged or incomplete.
■
Do not perform any modifications or changes to the towing device.
■
Never release the ball rod while the trailer is still coupled.
CAUTION
■ If there is an error in the trailer lighting system, check the fuses in the fuse box
in the dashboard. » page 200■
Handle the ball rod carefully to avoid damaging the paintwork on the bumper.
Note■
After coupling the trailer and connecting up the power socket, check the rear
lights on the trailer to ensure they work.■

ing » page 200 , Fuses in the dash panel or » page 201 , Fuses in the engine
compartment .
› Take the plastic clip located under the cover of the fuse box in the engine com-
partment, insert into the fuse and remove it » Fig. 173 on page 201.
› A blown fuses is recognisable by the molten metal strip. Replace the faulty fuse
with a new one of the same amperage.
The plastic clip can be found underneath the cover of the fuse box in the engine
compartment » Fig. 173 on page 201.
Electrically adjustable seats are protected by automatic circuit breakers, which
switch on again automatically after a few seconds after the overload has been
eliminated.

■ Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth, nap-
kin, or similar.
Note
■ This Owner's Manual only describes the replacement of bulbs where it is possi-
ble to replace the bulbs on your own without any complications arising. Other light bulbs should be changed by a ŠKODA specialist garage.■
We recommend that a box of replacement bulbs be always carried in the vehi-
cle. Replacement bulbs can be purchased from ŠKODAOriginal Accessories.
■
We recommend that the headlight settings are checked by a ŠKODA specialist
garage after replacing a bulb in the main or low beam, or the fog lights.
