Heating and air conditioning system
76
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 page 74, fig. 82 the warning light lights up in the
button.Switching recirculated air mode off– Once again press the button . The wa rning light in the button goes out.
The recirculated air mode is switched off automatically if the air distribution control
is in position
  page 74, fig. 82 . You can also switch recirculated air mode on again
from this setting by repeatedly pressing pushbutton .
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.Using the air conditioning system economicallyThe compressor on the air conditioning syst em 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 malfunctionsIf 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:
The fuse on the air conditioning system has blown. Check the fuse, replace it if
necessary page 169.

The cooling system has switched off auto matically for a short time because the
coolant temperature of the engine is too hot  page 16.
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.

Technical Data

Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper ating temperature - risk of damaging the
engine!

Vehicles which are fitted with an exhaust gas catalytic converter should not be tow-
started over a distance of more than 50 metres.For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away. Through
this the engine reaches its operating temperature more rapidly and the pollutant emis-
sions are lower.Petrol enginesThese 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
away and wait for about 30 seconds before repeating the attempt.

It is possible that the fuse on the electric al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary page 169.

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 enginesGlow 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 tempera-
ture.
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
away and 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 169.

Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the 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 tu rning the ignition key into position
 page 77, fig. 84 .
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 phys-
ical effort for braking is required when en gine 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.

Starting-off and Driving
80Note

The radiator fan may continue running fo r 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 co olant temperature rises because of an accu-
mulation 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 140, “Working in the engine compartment”.
ShiftingShift into reverse only when the vehicle is stationary. Depress the clutch pedal and hold
it fully depressed. Wait a moment before en gaging 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 pres-
sure of the hand will be transferred to the gearshift forks in the gearbox. This can, over
a period of time, lead to earl y wear of the gearshift forks.

Depress the clutch pedal fully when changi ng gears, in order to avoid unnecessary
wear and damage.
HandbrakeApplying the handbrake– Pull the handbrake lever up fully.Releasing the handbrake– Pull the handbrake lever up slightly and at the same time press in the locking
button fig. 86 .
– Hold the button pressed and push the handbrake lever down fully .
The handbrake warning light
 lights up when the handbrak e is applied, provided the
ignition is on.
A warning signal sounds if you have inadvertently driven off with the handbrake
applied.
The handbrake warning is activated if you drive at a speed of more than 6 km/h for
more than 3 seconds.

Towing a trailer
126
Further information on the towing device page 126.
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 allo wed 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, “Engine coolant temperature Display”.
If the needle of the coolant temperature gaug e 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 143,
“Inspecting the coolant level”.
Please refer to the following guidelines page 25, “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.
Detachable towing device*The ball head of the towing device is stowed together with separate fitting instructions
in the spare wheel well in the luggage compartment of the vehicle.


In view of the problems involved in prop erly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you have
the oil and oil filter change carried out by an authorised Škoda Service Partner.Note
After your skin has come in contact with th e oil, you must thoroughly wash your skin.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 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 concentration of antifreeze agent in the coolant by
adding water, also not during the summer mo nths 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 pr otection 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 offers 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 factor y-filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the same coolant additive - G12 PLUS-PLUS (purple in
colour) for topping up the system. Please contact an authorised Škoda Serv
ice Partner if you have any questions
regarding the coolant or if you wish to fill up with a different coolant.
An authorised Škoda Service Partner can also supply you with the correct coolant addi-
tives.

Caution

Other coolant additives may cause operational problems which, in particular,
involves significantly reduci ng the anticorrosion effect.

Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequenc e of this, result in major engine damage.
