Auxiliary heating (auxiliary heating and ventilation)
Introduction
The auxiliary heating heats the vehicle interior as well as the engine. For heat-
ing, fuel is consumed from the fuel tank.
The auxiliary ventilation enables fresh air to flow into the vehicle interior with
the engine switched off, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
The auxiliary heating (auxiliary heating and ventilation) (referred to just as auxil-
iary heating in the following) ensures the heating / ventilation depending on
the setting of the air conditioning and the air outlet vents before switching off
the ignition.
WARNING
The auxiliary heating must never be operated in closed rooms (e.g. garag-
■
es) – risk of poisoning!
The auxiliary heating must not be allowed to run during refuelling – risk of
■
fire.
The exhaust pipe of the auxiliary heating is located on the underside of
■
the vehicle. If you want to use the auxiliary heating, do not park the car in
places where the exhaust fumes can come into contact with flammable
materials such as dry grass, undergrowth, leaves, spilled fuel etc. - risk of
fire.

CAUTION
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.
Notice
The auxiliary heating switches the blower on, if it has achieved a coolant tem-
■
perature of approx. 50 °C.
In the engine compartment, water vapour may form during the operation of
■
the heater.
