Redirecting air flow
– The horizontal as well as the vertical direction of the air flow is
set with the handle in the middle of the air outlet vents.
You can set the air supply to the individual vents with the air distribution
control ⇒page 96, fig. 92 . Air outlet vents 3 and 4 can also be opened
or closed individually.
Unwarmed or cooled air will flow out of the opened air outlet vents
according to the setting of the control dial ⇒page 96, fig. 92 and
according to atmospheric conditions.
Climatic (semi-automatic air
conditioning system)*
Description
Climatic is a combined cooling and heating system with
electronic control of the convenience temperature in the
vehicle interior. It makes it possible to optimally control the
air temperature at any season of the year.
Description of the Climatic
It is important for your safety and for your driving comfort that the Climatic
is operating properly.
The air conditioning system operates when switch ⇒page 100,
fig. 94 is pressed and the following conditions are met:
•engine running,
•outside temperature above +2 °C and
•blower switch switched on (positions 1 to 4).
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 outside 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 the coolant temperature, thus full
heat output only occurs when the engine has reached its operating
temperature.
It is possible to briefly activate recirculated air mode in order to enhance
the cooling effect ⇒.
Air at a temperature of about 5°C may flow out of the vents under certain
circumstances when the cooling system is operating. 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.
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.
After switching on the cooling Condensation from the evaporator of the
air conditioning may drip down and form a puddle below the vehicle. This
is quite normal and not an indication of a leak!
WARNING
•For 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 correctly operate the 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

Using the air conditioni ng system economically
The compressor on the Climatic 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 interior has been strongly heated through the effect of direct sunlight
in order to allow the heated air to escape.
The cooling system should not be switched on while travelling when the
window is open.
The desired interior temperature can also be achieved without switching
in the cooling system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.
Operational problems
If the cooling system does not operate at outside temperatures higher
than +2 °C, there is a problem in the system. The reasons for this may be:
•The fuse of the Climatic is defective. Check the fuse, replace it if
necessary ⇒page 249.
•The cooling system has switched off automatically for a short time
because the coolant temperature of the engine is too hot ⇒page 14.
If you are not able to rectify the operational problem yourself, or if the
cooling capacity decreases, switch the cooling system off. Contact a
specialist garage.

Climatronic (automatic air conditioning)*
Description
The Climatronic system is a combination of an automatic
heating, fresh air and cooling system which provides
optimal comfort for the occupants of the car.
The Climatronic maintains a constant temperature fully automatically,
once it has been set. This is achieved by automatically varying the
temperature of the outflowing air, the blower stages and the air distribu-
tion. The system also takes into account sunlight which eliminates the
need to alter the settings manually. The automatic mode ⇒ page 106
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 +2 °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 outside 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 the coolant temperature, thus full
heat output only occurs when the engine has reached its operating
temperature.
It is possible to briefly activate recirculated 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 high 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 conditioning may drip down and form a puddle below the vehicle. This
is quite normal and not an indication of a leak!
Recommended setting for all periods of the year:
•Set the temperature to 22 °C.
•Press the button ⇒page 105, fig. 96 .
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly
upwards ⇒page 108, fig. 97 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒page 105, fig. 96 . 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 misting. Please familiarize
yourself about how to correctly operate the 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 recircu-
lated air mode off as soon as the windows begin misting up.

Starting-off and Driving
112
For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right
away. When driving the engine reaches its operating temperature more
rapidly and the pollutant emissions are lower.
Petrol engines
These engines are fitted with a starter system which selects the correct
fuel/air mixture for every external air temperature.
•Do not operate accelerator before and when starting engine.
•Interrupt the attempt at starting after 10 seconds if the engine does not
start right awayand wait for about 30 seconds before repeating the
attempt.
•It is possible that the fuse on the electrical fuel pump is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 249.
•If the engine does not start, contact the nearest specialist garage to
obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the
accelerator after the engine has started.
Diesel engines
Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period
being controlled automatically in line with the coolant temperature and
outside temperature. The preglow indicator light
 comes on after the ignition has been
switched on.
You should not switch on any major electrical components during
the heating period otherwise the vehicle battery will be drained
unnecessarily.
•You should start the engine immediately after the glow plug warning
light  has gone out.
•The glow plug warning light will come on for about one second if the
engine is at a normal operating temperature or if the outside temperature
is above +5°C. This means that you can start the engine right away.
•Interrupt the attempt at starting after 10 seconds if the engine does not
start right awayand wait for about 30 seconds before repeating the
attempt.
•It is possible that the fuse on the diesel preglow system is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 249.
•Contact the nearest specialist garage to obtain professional assist-
ance.
Starting the engine after fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel
tank has run completely dry - up to one minute. This is because the fuel
system must first of all be filled while the attempting to start the engine.
Switching off the engine
– The engine can be switched off by turning the ignition key from position ⇒page 110, fig. 100 into position .

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
WARNING
•Never switch off the engine before the vehicle is stationary - risk
of accident!
•The brake booster only operates when the engine is running.
Greater physical effort for brakin g is required when engine is
switched off. Because if you do not stop as normal, this can cause
an accident and severe injuries.
Caution
you should not switch the engine off right away at the end of your journey
after the engine has been operated for a lengthy period at high loads but
should be allowed it to run at idling speed for about 2 minutes. This
prevents any accumulation of heat when the engine is switched off.
Note
•The radiator fan may continue running for a further 10 minutes or so
after the engine and the ignition have been switched off. The coolant fan
may, however, also switch on again after some time if the coolant temper-
ature rises because of an accumulation of heat in the engine or if the
engine is warm and the engine compartment is additionally heated by
strong sunlight.
•This is why particular care is required when carrying out any work in
the engine compartment ⇒page 210, “Working in the engine
compartment”.
Shifting (manual gearbox)
Shift into reverse only when the car is stationary. Depress the clutch pedal
and hold it fully depressed. Wait a moment before engaging reverse gear
in order to avoid any shift noises.
The reversing lights will come on once reverse gear is engaged, provided
the ignition is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•One should not lay the hand on the shift lever while driving the vehicle.
The pressure of the hand will be transferred to the gearshift forks in the
gearbox. This can, over a period of time, lead to early wear of the gearshift
forks.

be found in your vehicle registration documents or in the brochure -
Technical Data .
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 pressure
Correct the tyre inflation pressure on your vehicle for that of “fully laden”,
⇒ page 226. 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 exterior mirrors fitted if you are not able to see
the traffic behind the trailer with the standard rear-view mirrors. Both exte-
rior mirrors 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 head-
lights. Alter the setting as necessary with the aid of the headlight beam
adjuster ⇒page 58.
Detachable ball head
The ball rod is detachable on vehicles with towing device and suppliable
from Škoda original accessories. It is stowed together with separate fitting
instructions in the spare wheel well in the luggage compartment of the
vehicle.
Note
•We recommend that you also have your 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 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 combination.
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
conditions, particularly near accident black spots.

Towing a trailer195
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
You must always reduce your speed immediately 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 engine speed when the
outside temperature is very high ⇒page 14.
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 216, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 31, “Coolant tempera-
ture/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 the slope without any drop in speed.
