heater SKODA OCTAVIA 2012 2.G / (1Z) User Guide

›The engine is also preheated when the vehicle is stationary and the engine is
not running;
› It warms up the coolant by burning fuel from the vehicle tank. The coolant
warms up the air, which (if the blower speed is not set to zero) flows into the passenger 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 refuelling - risk of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore, if you wish to operate the auxiliary heating, do not park the vehicle in such a way that the exhaust gases can come into contact with high-
ly flammable materials (e.g. dry grass) or easily inflammable substances (e.g.
spilt fuel).
CAUTION
■ The running auxiliary heater consumes fuel from the vehicle tank and automati-
cally controls the filling level. If only a low quantity of fuel is present in the fuel
tank, the function of the auxiliary heating 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 discharges.
If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometres in order to recharge
the vehicle battery.
Note
■ 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.
■
The air inlet in front of the windscreen must be free of e.g. ice, snow or leaves
to ensure that the auxiliary heating and cooling system operates properly.

Auxiliary heater: Radio remote control
First read and observe the introductory information and safety warn-

Explanation of graphicAAerialBBattery coverCWarning lightSwitch on the auxiliary heatingSwitch off the auxiliary heating
The transmitter and the battery are housed in the housing of the remote control.
The receiver is located in the interior of the vehicle.
When the battery is fully charged, the range of the remote control is a few hun-
dred metres. Obstacles between the radio remote control and the vehicle, bad
weather conditions and a weaker battery can clearly reduce the range.
To switch the auxiliary heating on or off, hold the remote control vertical, with the
aerial pointing upwards. The antenna must not be covered with the fingers or the palm of the hand during this process.
The auxiliary heating can only be switched on/off safely using the radio remote control, if the distance between the radio remote control and the vehicle is at
least 2 m.
After pressing the button, the warning light in the remote control gives the
user different kinds of feedback:

Avoiding full throttleFig. 96
Principle sketch: Fuel consump-
tion in litres/100 km. and speed
in km/h
The slower you drive, the more the fuel savings.
Sensitive use of the accelerator will not only significantly reduce fuel consump- tion but also positively influence environmental pollution and wear of your vehi-
cle.
The maximum speed of your vehicle should, as far possible, never be used. Fuel
consumption, pollutant emissions and vehicle noises increase disproportionally at
high speeds.
The » Fig. 96 shows the ratio of fuel consumption to the speed of your vehicle.
Fuel consumption will be halved if only three-quarters of the possible top speed
of your vehicle is used.

Reducing idling
Idling also costs fuel.
In vehicles not equipped with the START-STOP system, turn off the engine when
in a traffic jam, at a level crossing or traffic lights with longer wait times.
Even after just 30-40 seconds you will have saved more fuel than that is needed
when you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant emissions, though, are particularly
high in the warming-up phase. Therefore, start driving as soon as the engine has
started. whereby high engine speeds should be avoided.

Avoid short distancesFig. 97
Principle sketch: Fuel consump-
tion in l/100 km at different tem-
peratures
Short distances result in an above-average high fuel consumption. We therefore recommend avoiding distances of less than 4 km if the engine is cold.
A cold engine consumes the most fuel immediately after the start. Fuel consump- tion drops to 10 litres/100 km after just 1 kilometre. The consumption stabilises once the engine and catalytic converter have reached their operating tempera-
ture.
An important factor in this connection is also the ambient temperature. The im-
age » Fig. 97 shows the different levels of fuel consumption after driving a certain
distance at a temperature of +20 °C and a temperature of -10 °C.
Your vehicle has a higher fuel consumption in Winter than in Summer.

Convenience consumers
The convenience consumers include:
› The air conditioning system;
› Rear window heater;
› Windscreen heater;

We recommend you keep the convenience consumers on for as long as necessary. 
102Using the system

The automatic start procedure takes place again. The warning light goes out.
Further information on automatic transmission Engine shut down takes place when the selector lever is in positions P, D/S , N
and in Tiptronic mode.
When the selector lever is in position P the engine remains shut down after you
release the brake pedal. Start the engine by pressing the gas pedal or by choosing
a different gear and releasing the brake pedal.
If the selector lever is moved into position R during the STOP phase , the engine
will re-start.
To prevent the engine from starting unintentionally when selecting the position
R , switch rapidly from the position D/S to position P.
The system detects a movement of the vehicle due to the large steering angle or
when the selector lever is moved into position R (e.g. when parking) - no auto-
matic engine shutdown takes place.
The type of braking procedure can influence whether the STOP phase takes place
or not. No STOP phase takes place when the vehicle is moving at low speed (e.g.
during a traffic jam or when tuning) and remains stationary after pressing the
brake pedal lightly. Engine shutdown takes place if you press the brake pedal
down with more force.

A scraper to remove snow and ice from the windows and mirrors is located on the inside of the fuel filler flap . Remove the scraper from the fuel filler flap in the di-
rection of the arrow » Fig. 143.
Clean the windows from the inside on a regular basis. Dry the glass surfaces with a clean chamois leather or a cloth intended for thispurpose.
When drying the windows after washing the vehicle, do not use window leathers
that have been used to polish the bodywork. Residues of preservatives in the
window leather can dirty the window and reduce visibility.
CAUTION■ The ice scraper should not be moved forward and backward but in one direction
to avoid any damage to the surface of the glass.■
Snow or ice that is contaminated with coarse dirt such as fine gravel, sand, and
salt must not be removed from the window glass and mirrors – risk of damage to
the surface of the windows and mirrors.

162General Maintenance

We recommend maintaining the oil level within the range A, but not above , if
the engine has been operating at high loads, for example, during a lengthy motor-
way trip during the summer months, towing a trailer or negotiating a high moun- tain pass.
The warning light in the instrument cluster will indicate whether the oil level is too low » page 15 . Check the oil level using the dipstick as soon as possible. Add
oil accordingly.WARNINGDo not continue your journey if for some reason it is not possible  to top up
the engine oil under the prevailing conditions! Switch off the engine and seek
assistance from a ŠKODA specialist garage.
CAUTION
The oil level must on no account extend beyond the range A » Fig. 149 - Risk of
damaging the exhaust system!

Changing engine oil
First read and observe the introductory information and safety warn-
ings
on page 169.
The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator » page 11.
CAUTION
Do not pour any additives into the engine oil - Risk of serious engine damage!
Damage, which results from such product, are excluded from the warranty.
Note
If your skin has come into contact with oil, it must be washed thoroughly.
Coolant
First read and observe the introductory information and safety warn-ings
on page 169.
The coolant consists of water with a concentration of coolant additive. This mix-
ture guarantees antifreeze protection, protects the cooling/heater system
against corrosion and prevents the formation of scale.
Vehicles exported to countries with a mild climate are already factory-filled with
a coolant which offers antifreeze protection down to about -25 ℃. In these coun-
tries the concentration of coolant additive should be at least 40 %.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries the concentration of coolant additive should be at least 50 %.
If a higher concentration of antifreeze is required for climatic reasons, the amount
of coolant additive can only be increased up to a maximum of 60 % (antifreeze
protection down to approx. -40 °C).
When refilling, only use the same antifreeze written on the antifreeze expansion tank » Fig. 150 on page 174. 

CAUTION
■
The amount of coolant additive in the coolant must never be allowed to be less
than 40 %.■
Over 60 % of coolant additive in the coolant reduces the antifreeze protection
and coolant effectiveness.
■
Other coolant additives that do not comply with the correct specifications can
above all significantly reduce the anticorrosion effect.
■
Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage!

Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a ŠKODA spe- cialist garage.
WARNING Do not continue your journey, if for some reason it is not possible to top up
the coolant under the prevailing conditions! Switch off the engine and seek
assistance from a ŠKODA specialist garage. 1)
On vehicles that are fitted with an auxiliary heater (auxiliary heating and ventilation), the coolant ca-
pacity is approx. 1 l larger.
174General Maintenance

WARNING“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 196, Jump-starting in vehicles with the START-STOP
system .
Note
We recommend having the quick charging of vehicle batteries undertaken by a
ŠKODA specialist garage.
Disconnecting and reconnecting the vehicle battery

Note
We recommend having the vehicle checked by a ŠKODA Partner to ensure the full
functionality of all electrical systems.
Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 176.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the bettery is subjected to heavy loads. This manifests itself by the fol-
lowing:
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where appropriate large convenience consumers, e.g. seat heaters, rear win-
dow heaters, have their power limited or in case of emergency shut off com-pletely.
CAUTION
■ Despite such intervention by the vehicle electric system management, the vehi-
cle battery may be drained. For example, when the ignition is switched on a long
time with the engine turned off or the side or parking lights are turned on during longer parking.■
Consumers which are supplied via a 12 V socket can cause the vehicle battery to
discharge when the ignition is switched off.
Note
Driving comfort is not disrupted by any shutting off of consumers. Often the driv-
er is not aware of it having taken place.
