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 heater, then the car should not be
parked in places where the exhaust gases can come into contact with flam-
mable materials such as dry grass, undergrowth, leaves, spilled fuel or simi-
lar - Risk of fire.
CAUTION
The running auxiliary heater consumes fuel from the vehicle tank and auto-
■
matically controls the filling level. If only a low quantity of fuel is present in the
fuel tank, the auxiliary heating switches off.
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. If the auxili-
■
ary heating and ventilation has been operated several times over a longer peri-
od, the vehicle must be driven a few kilometres in order to recharge the vehi-
cle battery.
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.

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-

So that warm air can flow into the vehicle interior after switching on the aux-

iliary 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 po-
sition. It is recommended to put the air flow in the position or .
