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).
Auxiliary heating (auxiliary 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 heater functions in connection with the air-conditioning system
or Climatronic.
The auxiliary heating also warms up 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 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.
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, 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 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.

Using the system
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-
■
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 .
Switching on and off directly

Read and observe and
The auxiliary heating can be directly switched on or off at any time using the
button  » Fig. 118 on the operating part of the air-conditioning system , on
the operating part of the Climatronic system or via the radio remote control

If the auxiliary heating has not already been switched off, it switches off auto-
matically after the running time set in the Running time menu.
