Auxiliary heating (auxiliary heating and ventilation)


Introduction
This chapter contains information on the following subjects:
Switching on/off
Radio remote control
Conditions for the functioning of auxiliary heating (Aux. heating and ventilation),
hereinafter referred to only as auxiliary heating (Aux. heating).
The charge state of the vehicle battery is sufficient.

The fuel supply is adequate (the warning icon

instrument cluster).
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).
Auxiliary heating (aux. heating)
The auxiliary heating (aux. heating) can be used when stationary, when the en-
gine is switched off to preheat the vehicle and while driving (e.g. during the heat-
ing phase of the engine).
The auxiliary heating (auxiliary heating) functions in connection with the air-con-
ditioning system or Climatronic.
The auxiliary heating (aux. heating) also warms up the engine. This is not valid for
vehicles with the 3.6 l/191 kW FSI engine.
The auxiliary heating (parking heating) warms up the coolant by combusting fuel
from the vehicle tank. The coolant heats air flowing into the passenger compart-
ment (as long as the blower fan speed
page 103 is not set to zero).

WARNING
The auxiliary heating (aux. heating) must never be operated in closed rooms
■
(e.g. garages) – risk of poisoning!
The auxiliary heating (aux. heating) must not be allowed to run during refu-
■
elling – risk of fire.
The exhaust pipe of the auxiliary heating (aux. heating) is located on the un-
■
108
derside of the vehicle. Therefore, if you wish to operate the auxiliary heating
109
(aux. heating), do not park the vehicle in such a way that the exhaust gases
can come into contact with highly flammable materials (e.g. dry grass) or easily
inflammable substances (e.g. spilt fuel) – risk of fire.
CAUTION
Running auxiliary heating (aux. heating) consumes fuel from the vehicle tank
■
and automatically controls the filling level. If only a low quantity of fuel is present
in the fuel tank, the auxiliary heating (aux. heating) switches off.
The exhaust pipe of the auxiliary heating (aux. 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 (aux. heating) 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 (aux. heating) switches on the blower
■
page 100 or » Fig. 108 on page 103 only 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
on
problem.
The air inlet in front of the windscreen must be free (e.g. of ice, snow or leaves)
■
to ensure that the auxiliary heating (aux. 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, leave the fan switched on and leave the air outlet vents in an open position.
It is recommended to put the air flow in the position  or .
