open gas tank SKODA SUPERB 2009 Owner´s Manual

WARNING■The auxiliary heating must never be operated in closed rooms (e.g. garag-
es) – risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the heater, then the car should not be
parked in places where the exhaust gases can come into contact with flam- mable materials such as dry grass, undergrowth, leaves, spilled fuel or simi-
lar - Risk of fire.
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 112
or » Fig. 126 on page 115 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 

Unleaded petrol
Read and observe
and on page 183 first.
The vehicle can only be operated with unleaded petrol that meets the EN 2281)
standard.
All petrol engines can be operated using petrol with a maximum of 10% bioe-
thanol (E10).
Specified fuel - unleaded petrol 95/91 or 92 or 93 RON
Use unleaded fuel with an octane rating of 95 RON. Unleaded petrol with the
octane ratings 91 or 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 an octane rating of 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 or 92 or 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 fuel 98/95 RON
Use unleaded fuel with an octane rating of 98 RON or higher. Unleaded petrol
95 RON can also be used but results in a slight loss in performance.
In an emergency, if unleaded petrol with an octane rating of 98 RON or 95 RON
is not available, you may refuel with petrol with an octane rating of 91 or 92 or
93 RON »
.
Fuel additives
Unleaded petrol complying with EN 228 1 )
meets all the conditions for a smooth
running engine. We therefore recommend that no fuel additives are used. This
can result in considerable damage to parts of the engine or the exhaust sys-
tem. 
1)
In Germany also DIN 51626-1 or E10 for unleaded petrol with octane rating 95 or 91 or DIN 51626-2 or E5
