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.
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 (auxiliary heating and ventilation) (following only as
■
aux. heating) must never be operated in closed rooms (e.g. garages) – 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 heater, 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 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 is running, the vehicle battery discharges.
■
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.

Using the system
Note
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 operat-
ing problem.
So that warm air can flow into the vehicle interior after switching on the aux.
■
heating, you must maintain the comfort temperature normally selected by you,
leave the fan switched on and leave the air outlet vents in open. It is recom-
mended to put the air flow in the position  or .
