water pump SKODA OCTAVIA 2014 3.G / (5E) Owner's Manual

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 
.
