Technical Data
The AC compressor is switched off at a hi
gh coolant temperature in order to provide
cooling at a high load of the engine.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle be low the vehicle. This is quite normal and
not an indication of a leak!
If you make a change before switching off the ignition, which differs from the auto-
matic mode, the changed functi ons remain stored. Only the function “circulating air”
is erased 20 minutes after switching off the ignition.
Recommended setting for all periods of the year:

Set the temperature to 22 °C (72 °F).

Press the button page 83, fig. 97.

Move the air outlet vents 3 and 4, so that the air flow is directed slightly upwards
 page 77, fig. 94 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons 17 and 9 page 83, fig. 97 . The information
in the desired temperature measuring unit appears in the display.
WARNING

For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin g. Please familiarize yourself about
how to correctly operate th e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.

You should not leave recirculated air mode on over a longer period of time,
as “stale” air may result in fatigue in the driver and occupants, divert your
attention and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mode off as soon as the windows begin
misting up.Note

If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of deposits. Switch the cooling system on at
least once a month for approximately 5 minut es at the highest blower stage - also during the cold season of the year - in order to avoid such odours. Also open a window
for a short time.

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 evapor ator of the air conditioning system. This
produces a permanent odour when the air conditioning system is operating which can
only be eliminated through considerable effort and expense (replacement of
compressor).

The used air streams out through the air removal openings in the luggage compart-
ment.

Technical Data
Defrosting windscreen - switching off– Once again press the button or the button .
The temperature control is controlled automatically. More air flows out of the air outlet
vents 1 and 2.Recirculated air mode
In recirculated air mode air is sucked out of the interior of the vehicle
and then fed back into the interior.Recirculated air mode prevents polluted air outside the vehicle from getting into the
vehicle, for example when driving through a tunnel or when standi ng in a traffic jam.Switching recirculated air mode on– Press the button - the warning light lights up in the button.Switching recirculated air mode off– Press again the button or the button - the warning light in the button
goes out.
WARNING
You should not leave recirculated air mode on over a longer period of time, as
“stale” air may result in fatigue in the driver and occupants, divert your atten-
tion and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mode off as soon as the windows begin
misting up.
Note
If the windscreen mists up, press the button page 83, fig. 97 . After the wind-
screen has been demisted, press the button .Setting temperatureYou can set the interior temperature randomly with the buttons and . You can set the interior temperature betw
een +18°C (64°F) and +29°C (84 °F). The
interior temperature is regulated automatica lly within this range. If you select the
temperature below +18°C (64°F), “LO” appears in the display. If you select the temper-
ature higher than +29°C (84 °F ), “HI” appears in the display. In both limit positions the
Climatronic operates at ma ximum cooling or heating capacity, respectively. The
temperature is not controlled in this case.
Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg
area) and large differences in temperature, for example when getting out of the
vehicle, can result in chills in sensitive persons.
Controlling blower
There are a total of six blower stages available.The Climatronic system controls the blower st ages automatically in line with the inte-
rior temperature. You can also, however, adap t the blower stages manually to suit your
particular needs.
– Press the button or page 83, fig. 97 in order to decrease or increase the
speed.
Switch off the blowers, the Climatronic is switched off and in the display shows OFF.
The set blower speed is indicated by the ligh ting up of the respective number of bars
at the point .
WARNING

“Stale air” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an accident
increases.

Do not switch the Climatronic system off for longer than necessary.


Operational problemsIf all the symbols on the display of the au tomatic air conditioning system flash for
approx. 15 seconds after switching on the igniti on, then there is a fault in the system -
visit a specialist garage.
If the cooling system does not oper ate, the following faults may exist:
the outside temperature is lower than +5°C,

The compressor of the automatic air conditioning system was temporarily
switched off due to a too high temperature of the coolant,

a blown fuse.
Check the fuse, replace it if necessary page 177. If a blown fuse is not the source of
the fault, switch the Climatronic off and have it checked.
If the cooling capacity decreases, switch the Climatronic off and have it checked.

Towing a trailer
134
Towing a trailerTo w i n g a t r a i l e rTechnical requirements
The towing device must satisfy certain technical requirements.Your vehicle is designed primarily for tr ansporting persons and luggage. It can,
however, also be used for towing a traile r - provided certain technical equipment is
fitted.
If your vehicle has already been supplied with a factory-fitted towing device then
everything that is nece ssary for towing a trailer in technical terms, and in terms of the
law, has already been taken into account.
Your vehicle is fitted with a 13-pin power socket for the electrical connection between
the vehicle and trailer. If the tr ailer which you wish to tow has a 7-pin connector, you
can use a suitable adapter
5) from Škoda original accessories.
This work must be carried out in accordance with the manufacturer's specifications if
a towing device is retrofitted.
Specialist garages are familiar with details re lating to retrofitting a towing device and
for any necessary modifications to the cooling system.
WARNING
We recommend that you have the towing device from Škoda original accesso-
ries installed by a specialist garage. He is familiar with all the relevant details
relating to retrofitting such equipment. There is a risk of an accident if the
towing device is not properly fitted!
General Maintenance
There are a number of points to pay attention to when towing a trailer.Trailer load
The permissible trailer load must on no account be exceeded.
You can negotiate appropriately steeper inclin es and descents if you do not make full
use of the permissible trailer load.
The trailer loads specified only apply for altitudes up to 1 000 metres above mean sea
level. The fact that the engi ne power output drops with increasing height due to a
lowering of air pressure and thus the abil ity to climb, means that the towed weight
must be reduced by 10% for every further increase of 1 000 metres in height above sea
level. The towed weight is the weight of the (laden) vehicle and the (laden) trailer
together. One should take this into account before driving up to higher altitudes.
The trailer and drawbar load information on the type plate of the towing device
are merely test data for the towing device The data relating to your vehicle, which
is often less than this test data, can be found in your vehicle registration docu-
ments.
Distribution of the load
Distribute the load in the trailer in such a way that any heavy items are located as close
as possible to the axle. Secure th e items to prevent them slipping.
Tyre pressure
Correct the tyre inflation pressure on yo ur vehicle for that of “fully laden”, page 160.
The inflation pressure of the tyres fitted to the trailer adjust in accordance with the
manufacturer's recommendation.
Exterior mirrors
You have to have additional ex terior mirrors fitted if you are not able to see the traffic
behind the trailer with the standard rear-view mirrors. Both exterior mirrors should be
attached to folding arms. Adjust the mirrors so that they provide you with an adequate
field of view to the rear.
5)In some countries the adapter is supplied with the towing device.s2rc.book Page 134 Thursday, April 22, 2010 10:58 AM

Headlights
Before starting off with a hitched trailer, also check the setting of the headlights. Alter
the setting as necessary with the ai
d of the headlight beam adjuster page 48.
Detachable ball head
The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is
stowed together with separate fitting instructions in the spare wheel well in the
luggage compartment of the vehicle.
Further information on the towing device page 136.
Note

We recommend that you also have your vehicle inspected between service inter-
vals if you tow a trailer frequently.

The handbrake on the towing vehicle must be put on when coupling and decou-
pling the trailer.
Driving Tips
Particular caution is required when towing a trailer.– Do not, as far as possible, drive with your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temperature gauge if the outside temperature is high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer is
laden. Maintain a particularly low speed if you cannot avoid driving with this combina-
tion.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for countries
in which higher speeds are allowed. The fact that the driving stability of the vehicle + trailer combination reduces with
increasing speed means that the legally allowed speed should not be used when there
are unfavourable road, weather or wind cond
itions, particularly near accident black
spots.
You must always reduce your speed immediat ely as soon as you detect even just the
slightest swaying of the trailer. On no account attempt to stop the trailer from
“swaying” by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting from the
trailer wheels locking. Shift down gears in good time before negotiating a downhill
section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a
lengthy slope in a low gear at a high engi ne speed when the outside temperature is
very high  page 16.
If the needle of the coolant temperature gauge moves into the right-hand area or even
the red area of the scale, reduce your speed immediately. Stop and switch off the
engine if the warning light
 in the instrument cluster begins flashing. Wait a few
minutes and check the level of coolant in the coolant expansion bottle page 153,
“Inspecting the coolant level”.
Please refer to the following guidelines  page 28, “Coolant temperature/coolant
level ”.
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear and
increasing the engine speed is not possible since the fan speed is independent of the
engine speed. One should also not drop a gear for this reason when towing a trailer as
long as the engine can manage th e slope without any drop in speed.

Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the bonnet support
into the holder designed to hold it.
– Allow the bonnet to drop from a height of about 30 cm into the lock - bonnet do
not press down on it !
WARNING

Never open the bonnet if you see that steam or coolant is flowing out of the
engine compartment - risk of scalding! Wait long enough until the steam or
coolant has stopped escaping.

For safety reasons, the bonnet must always be properly closed when
driving. One should therefore check that the lock has in fact engaged properly
after closing the bonnet.

Stop your vehicle immediately while drivin g if you notice that the lock is not
properly engaged and close the bonnet properly - risk of an accident!
Working in the engine compartment
Particular care is required when carrying out any work in the engine
compartment!There is a risk of injuries, scalding, acci dents and fire when working in the engine
compartment, e.g. inspecting and replenishing oil and other fluids. For this
reason, it is essential to comply with the warning instructions stated below and
with the general applicable rules of safe ty. The engine compartment of your car
is a hazardous area  .
WARNING

Never open the bonnet if you see that steam or coolant is flowing out of the
engine compartment - risk of scalding! Wait long enough until the steam or
coolant has stopped escaping.

Switch off the engine and pull out the ignition key.

Apply the handbrake firmly.

On vehicles fitted with a manual gea rbox, move the gearshift lever into
Neutral.

Allow the engine to cool down.

Keep children clear of the engine compartment.

Never spill oil and other fluids over the hot engine. Such fluids (e.g. the anti-
freeze contained in the coolant) may ignite!

Avoid short circuits in the electrical system - particularly on the battery.

Never place your hand into the radiator fan as long as the engine is still
warm. The fan might suddenly start running!

Never open the cap of the coolant expans ion bottle as long as the engine is
still warm. The cooling system is pressurized!

Cover over the cap of the coolant expansion reservoir with a large cloth
when opening it as protection for your face, hands and arms from hot steam or
hot coolant.

Do not let objects, such as e.g cleaning cloth or tools lie in the engine
compartment.

If you wish to work under the vehicl e, you must secure the vehicle from
rolling away and support it with suitable supporting blocks; the lifting jack* is
not sufficient for this - risk of injury!

In cases where it be necessary to carry out inspection work when the engine
is running there is an additional risk fr om rotating parts (e.g. the V-ribbed belt,
alternator, radiator fan) and from the high-voltage ignition system. Please
observe in addition the following:
Never touch the electrical cabl es of the ignition system.
 Absolutely avoid any jewellery, loose it ems of clothing or long hair from
getting into the rotating parts of the engine - Hazard! Therefore remove any
jewellery beforehand, tie up your hair and wear tight fitting clothing.

Please also comply with the warnin g instructions stated below when
carrying out any essential work on the fu el system or on the electrical system:
 Always separate the car battery from the electrical system.
 Do not smoke.WARNING (continued)

Inspecting and replenishing
152For the sake of the environment

You must on no account pour oil into the ground or into the sewage system.

In view of the problems involved in prop erly disposing of old oil, the material,
equipment and the knowledge required for such work, we recommend that you have
the oil and oil filter change carried out by a specialist garage.Note
After your skin has come in contact with th e oil, you must thoroughly wash your skin.Power steeringThe reservoir for hydraulic oil of power steering is located in the front right of the
engine compartment page 149, fig. 145 .
Check hydraulic oil
The hydraulic system of the power steering is filled with the hydraulic oil designated in
the catalogue as G 002 000.
Perform the inspection of the hydraulic oil level when the engine is cold and not
running.
The hydraulic oil level must be be tween the “MIN” and “MAX” markings fig. 147 . If
the level drops below the marking “MIN”, it is necessary that the power steering is
checked by a specialist garage. It is not su fficient to solely refill with hydraulic oil.
Note
If the engine is not running (when towing) or if the V-ribbed belt is torn, the power
steering does not operate. The vehicle is fully steerable however. There is however
increased force required to turn the steering wheel.Cooling systemCoolant
The job of the coolant is to cool the engine.The cooling system does not require any maintenance under normal operating condi-
tions. The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture not only provides antifreeze prot ection down to -25°C but also protects
the cooling and heating system from corrosion. It also prevents the formation of scale
and significantly increases the boiling point of the coolant.
You must therefore not reduce the concentration of antifreeze agent in the coolant by
adding water, also not during the summer mont hs or in countries with a warm climate.
The concentration of coolant additive in the coolant must be at least 40%.
You can increase the amount of antifreeze in the coolant if a higher concentration of
antifreeze is necessary for climatic reasons but only up to 60% (antifreeze protection
down to approx. -40°C). The antifreeze protection tails off above that concentration.
Vehicles exported to countries with a cold climate (e.g. Sweden, Norway, Finland) are
already factory-filled with a coolant which of fers antifreeze protection down to about
-35°C. In these countries the concentration of coolant additive should be at least 50%.
Coolant
The cooling system is factory- filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the same coolan t additive - G13 (purple in colour) - for
topping up the system.
Please contact a specialist garage if you have any questions regarding the coolant or if
you wish to fill up with a different coolant.
A specialist garage can also supply yo u with the correct coolant additives.
