Climatronic* (automatic air conditioning)Description The Climatronic system is a combin
ation of an automatic heating,
fresh air and cooling system which provides optimal comfort for the occupants of the car.The Climatronic maintains a constant temp
erature fully automatically, once it has
been set. This is achiev
ed by automatically varying the temperature of the
outflowing air, the blower stages and the ai
r distribution. The system also takes into
account bright sunlight which eliminates
the need to alter the settings manually.
The
automatic mode
⇒page 90 ensures maximum wellbeing of the occupants at
all times of the year. Description of Climatronic system The cooling operates only if the following conditions are met:•
engine running,
•
outside temperature above +5 °C,
•
the button is
not
pressed.
If the cooling system is switched on, the temperature and air humidity drops in the vehicle. The wellbeing of the occupants of
the car is enhanced as a result of this
particularly at high outs
ide temperatures and a high air humidity. The system
prevents the windows misting up during the cold season of the year. The heating effect is dependent upon th
e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature. It is possible to briefly activate recirc
ulated air mode in order to enhance the
cooling effect
⇒
.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to ensure that the heating and cooling systems operate properly. 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 functions 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).

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 mi
nutes at the highest blower stage - also
during the cold season of the year - in
order to remove 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 inte- rior of the vehicle forms deposits in the
evaporator 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 (replace- ment of compressor).•
The used air streams out through the air removal openings in the luggage
compartment.•

. After the
windscreen has been demisted, press the button .Setting temperatureYou can set the interior temperature randomly with the buttons and
.
You can set the interior temperature between +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” appe
ars in the display. If you select the
temperature higher than +29°C (84 °F), “H
I” appears in the display. In both limit
positions the Climatronic operates at
maximum 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 bl
ower stages automatically in line
with the interior temperature. You
can also, however, adapt the blower
stages manually to suit
your particular needs.

WARNING
•
“Stale air” may result in fatigue in
the driver and occupants, reduce
attention levels and also cause the windows to mist up. The risk of having an accident increases.•
Do not switch the Climatronic syst
em off for longer than necessary.
•
Switch the Climatronic system on as soon as the windows mist up.
Operational problemsIf all the symbols on the display of the au
tomatic air conditioning system flash for
approx. 15 seconds after switching on the ignition, 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 192. 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
144
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 te
chnical equipment is
fitted. If your vehicle has already been supplied with a
factory-fitted
towing device then
everything that is necessary
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 po
wer socket for the electrical connection
between the vehicle and trailer. If th
e trailer 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 accordan
ce with the manufacturer's specifications
if a towing device is retrofitted. Specialist garages are familiar with details
relating 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 acces-sories installed by a specialist garage.
He is familiar with all the relevant
details relating to retrofitting such equi
pment. 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 appropriatel
y steeper inclines and desc
ents if you do not make
full use of the perm
issible trailer load.
The trailer loads specified only apply for
altitudes
up to 1 000 metres above mean
sea level. The fact that the engine power ou
tput 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 alti- tudes. The trailer and drawbar load information on the type plate of the towing device are merely test data for the tow
ing device The data relating to your
vehicle, which is often less than this test data, can be found in your vehicle registration documents. 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
the items to prevent them slipping.
Tyre inflation pressure Select the tyre inflation pressure on your vehicle for that of “fully laden”, ⇒ page 173. The inflation pressure of the tyres fitted to the trailer adjust in accord- ance with the manufacturer's recommendation. 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. Both exterior mirrors
5)In some countries the adapter is
supplied with the towing device.

should be attached to folding arms. Adjust
the mirrors so that they provide you with
an adequate field of view to the rear. Headlights Before starting off with a hitched trailer, also check the setting of the headlights. Alter the setting as necessary with th
e aid of the headlight beam adjuster
⇒ page 51. 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 146.
Note
•
We recommend that you also have yo
ur vehicle inspected between service
intervals if you tow a trailer frequently.•
The handbrake on the towing vehicle
must be put on when coupling and
decoupling 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 temper
ature gauge if the outside temper-
ature 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 combination. Driving speed Do not drive faster than 80 km/hour for safety reasons. This also applies for coun- tries 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
conditions, particul
arly near accident
black spots. You must always reduce your speed immedi
ately 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 down-
hill 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 engine 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 yo
ur speed immediately. Stop and switch off
the engine if the warning light
 in the instrument cluste
r begins flashing. Wait a
few minutes and check the level of coolant in the coolant expansion bottle ⇒ page 165, “Inspecting the coolant level”. Please refer to the following guidelines
⇒page 30, “Coolant temperature/ Coolant
quantity
”.
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

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 scaldi
ng! 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 prop-
erly after closing the bonnet.•
Stop your vehicle i
mmediately while driving if yo
u notice that the lock is
not properly engaged and close the bonn
et properly - risk of an accident!
Working in the engine compartment Particular care is required when ca
rrying out any work in the engine
compartment!There is a risk of injuries, scalding,
accidents and fire wh
en working in the
engine compartment, e.g. inspecting an
d 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 safety. The engine compart-
ment 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 scaldi
ng! 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 gearbox, 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
antifreeze 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 expa
nsion 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 from 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 items of clothing or long hair from getting into the rotating part
s of the engine - Hazard! Therefore

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 between the “MIN” and “MAX” markings ⇒ page 164, fig. 153
. If the level drops below the mark
ing “MIN”, it is necessary that
the power steering is checked by a specialist
garage. It is not sufficient 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 an
y maintenance under normal operating
conditions. The coolant consists of water
with a concentration of coolant additive
of 40 %. This mixture not only provides
antifreeze protection 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 concentr
ation of antifreeze agent in the coolant
by adding water, also not during the summ
er months 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 an
tifreeze protection tails off above that
concentration.
Vehicles exported to countries with a co
ld climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant which offers antifreeze protection down to about -35°C. In these countries the concentr
ation 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 c
oolant additive - G12 PLUS-PLUS (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
you with the correct coolant additives.
Caution
•
Other coolant additives may cause operational problems which, in partic-
ular, involves significantly reducing the anticorrosion effect.•
Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th
is, result in major engine damage.
