2014 SKODA OCTAVIA fuel pump

CAUTION■The running auxiliary heater consumes fuel from the vehicle tank and auto-
matically controls the filling level. If only a low quantity of fuel is present in the
fuel tank, the auxiliary heating switches off.■
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 is running, the vehicle battery discharges. If the auxili-
ary heating and ventilation has been operated several times over a longer peri-
od, the vehicle must be driven a few kilometres in order to recharge the vehi-
cle battery.
■
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly.
Note
■ The auxiliary heating switches on the blower B » Fig. 125 on page 119 orC » Fig. 126 on page 119 only if it has achieved a coolant temperature of ap-
prox. 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 operat-
ing problem.
■
So that warm air can flow into the vehicle interior after switching on the aux-
iliary heating, you must maintain the comfort temperature normally selected
by you, leave the fan switched on and leave the air outlet vents in an open po-
sition. It is recommended to put the air flow in the position 
or 
.
Switching on/off

part of the air conditioning/Climatronic
Read and observe and on page 121 first.
The auxiliary heating can be switched on/off as follows.
Manually switching on Using the button on the operating part of the manual air conditioning/Cli-
matronic. The indicator light in the button illuminates » Fig. 127.
By using the radio remote control » page 123.
Manually switching off Using the button on the operating part of the manual air conditioning/Cli-
matronic. The indicator light in the button goes out » Fig. 127.
By using the radio remote control » page 123.
After switching the system off, the auxiliary heating will continue running a lit- tle while longer in order to burn the remaining fuel in the auxiliary heater.
After switching off the auxiliary heating, the coolant pump still runs for a short
period.
Switching on automatically
The auxiliary heater is switched on according to the Infotainment set-
tings » Infotainment manual , chapter Vehicle settings .
When automatic switching on is activated, the indicator light in the symbol
button  lights up for about 10 seconds after the ignition is turned off.
Switching off automatically
Turning off the auxiliary heating occurs in the following cases.
› The switch-off time set in Infotainment has been achieved
» Operating in-
structions for Infotainment , chapter Vehicle settings .
› The fuel level has reached the reserve area (the warning icon
 illuminates).
› The charge state of the vehicle battery has reduced too much

The correct fuels for your vehicle are specified on the inside of the fuel filler
flap » Fig. 180 on page 188 .
WARNING■
Observe the local regulations regarding fuel handling.■The operating instructions of the refuelling system must always be fol-
lowed.■
Do not smoke when refuelling and do not use a mobile phone.
■
The fuel and fuel vapours are explosive - risk to life!
CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of
fuel can cause misfiring, which can result in damage to parts of the engine and
the exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork –
risk of paint damage!
■
If the vehicle was not purchased in the country where it was intended to be
operated, you should check whether the fuel specified by the manufacturer is
offered in the country where the vehicle will be operated. You should also per-
haps check whether the manufacturer has recommended a different fuel for
operation of the vehicle in the corresponding country. If no prescribed fuel is
available, then you must check whether it is permitted by the manufacturer to
operate the vehicle with another fuel type.

The vehicle is unlocked.
The engine and the ignition are switched off simultaneously.

Close the fuel filler flap until it clicks into place.
Check that the fuel filler flap is closed properly.
Incorrect refuelling guard on vehicles with diesel engines
The fuel filler tube on vehicles with diesel engines has been fitted with a in-
correct refuelling guard » Fig. 181. This guard means it is only possible to refuel
with the diesel pump nozzle.
If the diesel pump nozzle does not sit directly in the fuel filler tube, move it to
and fro with slight pressure to insert it correctly.
WARNINGInstructions for filling the reserve canister■Never fill the reserve can inside the vehicle.■
Never place the reserve can on the vehicle.
■
Always place the reserve can on the floor.
■
The national legal requirements must be observed if carrying a spare can-
ister in the vehicle.
■
We do not recommend carrying any fuel canisters in your vehicle for safe-
ty reasons. in the event of an accident this can get damaged and fuel may
escape – risk of fire!
CAUTION
■ The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Not continue refuelling.■
Be careful when filling diesel fuel from the spare canister and then do this
slowly and cautiously – danger of contaminating the body.
■
The diameter of the diesel pump nozzle can be identical to that of the petrol
pump nozzle in some countries. When driving in these countries, the incorrect
fuelling protection should be removed by a specialist company.
Note
The fuel tank has a capacity of about 50 litres, including a reserve of approx.
6 litres .Lead-free petrol
Read and observe
and on page 188 first.
The vehicle can only be operated with unleaded petrol that meets the EN 2281)
standard.
All petrol engines can be operated using petrol that contains at most 10% bio-
ethanol (E10).
Required fuel - unleaded petrol 95/91 or 92 or 93 RON
Use unleaded fuel with the octane rating 95 RON. Unleaded petrol with the
octane ratings 91, 92 or 93 RON can also be used, but may result in a slight
loss in performance and slightly increased fuel consumption »
.
Prescribed fuel – unleaded petrol min. 95 RON
Use unleaded fuel with the octane rating 95 RON or higher.
If unleaded gasoline is not available with the octane number 95 RON, in an
emergency petrol with the octane rating of 91, 92 and 93 RON can be used to
fill the tank, but this leads to a slight loss of performance and a slightly in-
creased fuel consumption »
.
Prescribed fuel – unleaded petrol 98/(95) RON
Use unleaded fuel with the octane rating 98 RON or higher. Unleaded petrol
95 RON can also be used but this results in a slight loss in performance and
slightly increased fuel consumption.
In case of an emergency, you can refuel with petrol with the octane ratings 91,
92 or 93 RON, if unleaded fuel with octane rating 98 RON or 95 RON is not
available »
.
Fuel additives
Unleaded petrol in accordance with the EN 228 standard 1)
meets all the condi-
tions for a smooth-running engine. We therefore recommend that no fuel ad-
ditives are used. This can result in considerable damage to parts of the engine
or the exhaust system. 
1)
In Germany also DIN 51626-1 or E10 for unleaded petrol with octane number 91 or 95 or DIN 51626-2 or E5
for unleaded petrol with octane number 95 and 98.
