Auxiliary heating (parking heating)
The auxiliary heating (auxiliary heating) functions in connection with the air-con-
ditioning system or Climatronic.
It can be used when stationary, when the engine is switched off to preheat the
vehicle and while driving (e.g. during the heating phase of the engine).
The engine is also preheated, if the auxiliary heating is switched on when the ve-
hicle is stationary and the engine is switched off. 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 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 from the auxiliary heating can
come into contact with highly flammable materials (e.g. dry grass) or easily in-
flammable substances (e.g. spilt fuel).

Using the system
Note
If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
■
The auxiliary heating automatically controls the filling level in the fuel tank. 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
■
101
the vehicle, must not be clogged and the exhaust flow must not be blocked.
101
If the auxiliary heating and ventilation is running, the vehicle battery discharges.
■
101
If the auxiliary heating and ventilation has been operated several times over a
102
longer period, the vehicle must be driven a few kilometres in order to recharge
the vehicle battery.
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.
After switching off the auxiliary heating, the coolant pump runs for a short peri-
■
od.
The auxiliary heating and ventilation does not switch on or comes on, if the ve-
■
hicle battery indicates a low loading state
tion.
The auxiliary heating (parking heating) does not switch on, if the following was
■
shown in the information display or before switching off the ignition: Please re-
fuel!
The air inlet in front of the windscreen must be free of ice, snow or leaves in
■
order to ensure that the auxiliary 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 .
