WARNING■The auxiliary heating (auxiliary heating and ventilation) (hereinafter refer-
red to as aux. 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, do not switch off the car in pla-
ces where the exhaust fumes can come into contact with flammable mate-
rials 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. 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.
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
