Auxiliary heating (auxiliary heating and ventilation)*
Description and important information
The auxiliary heating (auxiliary heating and ventilation) heats or
supplies the interior of the vehicle with fresh air independent of the
engine.
Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) functions in connection with the Climatic or
Climatronic.
It can be used when stationary, when engine is switched off for preheating of the
vehicle as well as while driving (e.g. during the heating phase of the engine).
The engine is also preheated when the vehicle is stationary and the engine is switched
off, if the auxiliary heating is switched on. This is not valid for the engines 3.6 ltr./191 kW
FSI and 1.9 ltr./77 kW TDI.
The auxiliary heating (auxiliary heating) warms up the coolant during the combustion
of fuel from the vehicle tank. The coolant warms up the air, which (if the blower speed
is not set to zero) flows into the occupant 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 decreased (e.g. with the
vehicle parked in the sun).
WARNING
 The auxiliary heating must never be operated in closed rooms - risk of
poisoning!
 The auxiliary heating must not be running during refueling - risk of fire.
 The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore do not place the vehicle, if you wish to operate the auxiliary
heating, in such a way that the exhaust gases of the auxiliary heating can come
easily into contact with inflammable materials (e.g. dry grass) or easily inflam-
mable substances (e.g. fuel run out).
Note
 If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
Therefore the auxiliary heating should not be operated, if there is very little fuel in the
tank.
 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 and ventilation 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 kilometers 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 period.
 The auxiliary heating and ventilation does not switch on or comes on, if the vehicle
battery indicates a low loading state.
 The auxiliary heating (auxiliary heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please refuel!
 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.
