2011 SKODA OCTAVIA engine

Heating and air conditioning system
Introduction
Description and information The heating effect is dependent upon the coolant temperature, thus full heat out-
put 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 in order to enhance the cool-
ing effect - air-conditioning system ⇒ page 90
, Climatronic ⇒ page 93.
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 condi-
tioning 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 win-
dows 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 at-
tention 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
● The used air streams out through the air removal openings 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).
● Please refer to the information regarding the recirculated air mode for heating
⇒

  page 88 and/or for air-conditioning system ⇒ page 90 or Climatronic
⇒  page 93.
● To ensure the heating system, air conditioning system or Climatronic work per-
fectly, the air outlet vents must not be covered by any objects. 
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.
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 +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 211.
● The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot ⇒ page 11.
If you are not able to rectify the operational problem yourself, or if the cooling ca-
pacity decreases, switch the cooling system off. Contact a specialist garage.  85

The cooling only operates if button
AC ⇒ 
fig. 94 1 is pressed, and the following
conditions are met:
● engine running,
● outside temperature above approx. +2 °C and
● blower switch switched on (positions 1 to 4).
Air at a temperature of about 5 °C may flow out of the vents under certain circum-
stances when the cooling system is operating. Lengthy and uneven distribution of
the air flow out of the vents and large differences in temperature, for example
when getting out of the vehicle, can result in chills in sensitive persons. Note
● We recommend that you have the air conditioning system cleaned by a spe-
cialist garage once every year. 

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 in-
creases. Switch recirculated air mode off as soon as the windows begin mist-
ing up. 
Climatronic (automatic air conditioning) Description The Climatronic system is an automatic heating, fresh air and cool-
ing system which provides optimal comfort for the occupants of the
car.
The Climatronic maintains fully automatically a convenience temperature. This is
achieved by automatically varying the temperature of the outflowing air, the
blower stages and the air distribution. The system also takes into account sun-
light which eliminates the need to alter the settings manually. The automatic
mode
⇒

 page 92 ensures maximum well-being 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 approx. +2 °C,
● AC switched on.
The AC compressor is switched off at a high coolant temperature in order to pro-
vide cooling at a high load of the engine.
Recommended setting for all periods of the year:
● Set the desired temperature, we recommend 22 °C.
● Press the button AUTO
⇒  fig. 95 .
● Move the air outlet vents 3 and 4 so that the air flow is directed slightly up-
wards. Note
● We recommend that you have Climatronic cleaned by a specialist garage once
every year.
● On vehicles equipped with a factory-fitted radio or radio navigation system,
the information of the Climatronic is also shown on the display. This function can
be switched off, see operating instructions of the radio or the radio navigation
system. 

Auxiliary heating (auxiliary heating and ventilation)
Description and important information The auxiliary heating (auxiliary heating and ventilation) heats or
supplies the interior of the vehicle with fresh air independent of the
engine.
Auxiliary heating (parking heating)
The auxiliary heater (parking heater) functions in connection with the air-condi-
tioning system or Climatronic.
It can be used when stationary, when engine is switched off for preheating of the
vehicle as well as while driving (e.g. during the heating phase of the engine).
The engine is also preheated when the vehicle is stationary and the engine is
switched off, if the auxiliary heating is switched on.
The auxiliary heating (parking heating) warms up the coolant during the combus-
tion of fuel from the vehicle tank. The coolant warms up the air, which (if the
blower speed is not set to zero) flows into the occupant compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun). WARNING
● The auxiliary heating must never be operated in closed rooms - risk of poi-
soning!
● The auxiliary heating must not be running during refueling - risk of fire.
● The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. Therefore do not place the vehicle, if you wish to operate the aux-
iliary heating, in such a way that the exhaust gases of the auxiliary heating
can come easily into contact with inflammable materials (e.g. dry grass) or
easily inflammable substances (e.g. fuel run out). Note
If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
The auxiliary heating automatically controls the filling level in the fuel tank. If only
a low quantity of fuel is present in the fuel tank, the function of the auxiliary heat-
ing is blocked.
● The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
● If the auxiliary heating and ventilation is running, the vehicle battery discharg-
es. If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometers in order to recharge the
vehicle battery.
● The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.
● At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating
problem.
● After switching off the auxiliary heating, the coolant pump runs for a short pe-
riod.
● The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicates a low loading state ⇒

 page 190, Automatic consumer
shut-off.
● The auxiliary heating (parking heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please re-
fuel!
● The air inlet in front of the windscreen must be free of ice, snow or leaves in
order to ensure that the auxiliary heating operates properly.
● So that warm air can flow into the vehicle interior after switching on the auxili-
ary heating, you must maintain the comfort temperature normally selected by you
and leave the air outlet vents in an open position. It is recommended to put the air
flow in the position  or . 94

Starting-off and Driving
Setting steering wheel position Fig. 98 Adjustable steering wheel: Lever below the steering wheel/safe distance to the
steering wheel
You can set the height and the forward/back position of the steering wheel to the
desired position.
– Adjust the driver seat ⇒  page 60, Adjusting the front seats.
– Pull the lever below the steering wheel down ⇒ fig. 98 - left ⇒
  .
– Set the steering wheel to the desired position (concerning height and forward/
back position).
– Push the lever upwards as far as the stop. WARNING
● You must not adjust the steering wheel when the vehicle is moving!
● The driver must maintain a distance of at least 25 cm to the steering wheel
⇒ fig. 98 - right. Not maintaining this minimum distance will mean that the air-
bag system will not be able to properly protect you - hazard!
● For safety reasons the lever must always be firmly pushed up to avoid the
steering wheel altering its position unintentionally when driving - risk of acci-
dent! WARNING (Continued)
● If you adjust the steering wheel further towards the head, you will reduce
the protection offered by the driver airbag in the event of an accident. Check
that the steering wheel is aligned to the chest.
● When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock position. Never hold the steering wheel
firmly in the 12 o'clock position or in another way (e.g. in the middle of the
steering wheel or at the inner steering wheel edge). In such cases, injuries to
the arms, the hands and the head can occur when the driver airbag is de-
ployed. 
Ignition lock Fig. 99 Ignition lock positions
Petrol engines 1 - ignition switched off, engine off, the steering can be locked.
2 - ignition switched on
3 - start engine
Diesel engines 1 - interruption of fuel supply, ignition switched off, engine off, the steering can
be locked.
2 - heating glow plugs on, ignition switched on
● You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily. £98
Starting-off and Driving

3
- start engine
Applies to all models:
Position 1 To
lock the steering , with the ignition key withdrawn, turn the steering wheel un-
til the steering locking pin is heard to engage. You should always lock the steering
as a general rule if you leave your vehicle. This acts as a deterrent against possible
theft of your vehicle ⇒  .
Position 2 Move the steering wheel back and forward a little if the ignition key cannot, or
cannot easily be turned into this position, in order to release the steering lock.
Position
3 The engine is started in this position. At the same time switched on low beam or
main beam or other electrical components with major power consumption are
briefly switched off. The ignition key moves back into position
2 when one relea-
ses the key.
The ignition key must be turned back into position 1 each time before starting
the engine again. The starter repeat lock in the ignition lock prevents the starter
being engaged when the engine is running and thus getting damaged.
Ignition key withdrawal lock (automatic gearbox)
You can only withdraw the ignition key after switching off the ignition if the selec-
tor lever is in position P.WARNING
● When driving, the ignition key must always be in the position 2 (ignition
switched on) without the engine running. This position is indicated by the
warning lights coming on. If this is not the case, it could result in unexpected
locking of the steering wheel - risk of accident!
● Only remove the ignition key from the ignition lock when the vehicle has
come to a standstill (by applying the handbrake or moving the selector lever
into the position
P). The steering lock can engage immediately - risk of acci-
dent!
● Always withdraw the ignition key if you are going to leave the vehicle,
even for a short time. This is particularly important if children are left in the
vehicle. The children might otherwise start the engine or switch on electrical
equipment (e.g. power windows) - risk of accident or injury! Starting the engine
General You can only start the engine only using an original ignition key.
Manual gearbox
– Place the gearshift lever into neutral and put on the handbrake firmly before
starting the engine.
– Engage the clutch pedal and keep it depressed until the engine starts.
If you start the engine without depressing the clutch pedal, the engine does not
start and the following message appears in the Information display Depress
clutch! or CLUTCH in the display of the instrument cluster.
– Let go of the key as soon as the engine starts otherwise there may be damage
to the starter.
Automatic gearbox
– Place the gearshift lever into P or N before starting the engine, and apply the
handbrake firmly.
– Let go of the key as soon as the engine starts otherwise there may be damage
to the starter.
The engine running noises may louder at first be louder for a short time after
starting the cold engine until oil pressure can be built up in the hydraulic valve
clearance compensation. This is quite normal and is not an operating problem.
If the engine does not start ...
You can use the battery of another vehicle as a jump-start aid ⇒

 page 206. WARNING
● Never run the engine in non ventilated or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon mon-
oxide a poisonous gas - hazard! Carbon monoxide can cause unconsciousness
and death.
● Never leave your vehicle unattended with the engine running. £ 99
Starting-off and Driving Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data

CAUTION
● The starter may only be operated (ignition key position 3 ), if the engine is not
running. If the starter is immediately operated after switching off the engine, the
starter or the engine can be damaged.
● Avoid high engine revolutions, full throttle and high engine loads as long as
the engine has not yet reached its normal operating temperature - risk of damag-
ing the engine!
● Do not tow start the engine - danger of damaging the engine. On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. You can
use the battery of another vehicle as a jump-start aid ⇒ page 206
, Jump-starting.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 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 211.
● 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 temper-
ature.
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 211.
● 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 turning the ignition key into position 1 ⇒ 
fig. 99 . WARNING
● Never switch off the engine before the vehicle is stationary - risk of acci-
dent!
● The brake booster only operates when the engine is running. Greater
physical effort for braking 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 al-
lowed it to run at idling speed for about 2

minutes. This prevents any accumula-
tion of heat when the engine is switched off. £100
Starting-off and Driving

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, al-
so switch on again after some time if the coolant temperature rises because of an
accumulation of heat in the engine or if the engine is warm and the engine com-
partment is additionally heated by strong sunlight.
● This is why particular care is required when carrying out any work in the en-
gine compartment ⇒
 page 181, Working in the engine compartment. 
Shifting (manual gearbox) Fig. 100 The shift pattern: 5-speed or 6-
speed 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 igni-
tion 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.
● Depress the clutch pedal fully when changing gears, in order to avoid unneces-
sary wear and damage. Pedals Operation of the pedals must not be hindered!
WARNING
● In the driver's footwell, only a footmat, which is attached to the two corre-
sponding attachment points, may be used.
● No objects are allowed in the driver's footwell – risk of obstruction or limi-
tation in operating the pedal! Note
● Greater brake pedal distances may be needed when there is a fault in the
brake system.
● Use only footmats from the range of ŠKODA Original Accessories, which are at-
tached at two attachment points. 
