Functional requirements of the auxiliary heating (aux. heating and ventilation) The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning light is not illuminated in the
instrument cluster).
Aux. heating
The auxiliary heating can be used when both when stationary, when the en-
gine is switched off, to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The auxiliary heating warms up the coolant by combusting fuel from the vehi-
cle tank. This heats the air flowing into the passenger compartment (if the
blower is turned on).
The auxiliary heating also warms up the engine.
The heater is switched on or off automatically depending on the ambient con-
ditions to give the best possible conditions for the engine running and the in-
terior heating.
For vehicles with gasoline engines, the automatic switching on and off of the
heater can be disabled in a specialist workshop.
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).
