WARNING
•
"Stale air" may result in fatigue in the driver and occupants, reduce attention
levels and also cause the windows to mist up. The risk of having an accident
increases.
•
Do not switch the Climatronic system off for longer than necessary.
•
Switch the Climatronic system on as soon as the windows mist up.

Auxiliary heating (auxiliary heating and ventilation)

Description and important information
The auxiliary heating (auxiliary heating and ventilation) heats or
supplies the interior of the vehicle with fresh air independent of the
engine.
Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) functions in connection with the heating
system. Air-conditioning system or Climatronic.
It can be used when stationary, when engine is switched off for preheating of the
vehicle as well as while driving (e.g. during the heating phase of the engine).

The engine is also preheated when the vehicle is stationary and the engine is
switched off, if the auxiliary heating is switched on.
The auxiliary heating (auxiliary heating) warms up the coolant during the combus-
tion of fuel from the vehicle tank. The coolant warms up the air, which (if the blower
speed is not set to zero) flows into the occupant compartment.
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 decreased
(e.g. with the vehicle parked in the sun).
WARNING
•
The auxiliary heating must never be operated in closed rooms - risk of
poisoning!
•
The auxiliary heating must not be running during refueling - risk of fire.
•
The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore do not place the vehicle, if you wish to operate the auxiliary
heating, in such a way that the exhaust gases of the auxiliary heating can come
easily into contact with inflammable materials (e.g. dry grass) or easily inflam-
mable substances (e.g. fuel run out).
Note
If the auxiliary heating runs, the fuel consumption comes from the vehicle tank. The
auxiliary heating automatically controls the filling level in the fuel tank. If only a low
quantity of fuel is present in the fuel tank, the function of the auxiliary heating is
blocked.
•
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 and ventilation is running, the vehicle battery discharges.
If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometers in order to recharge the
vehicle battery.
•
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 operating
problem.
•
After switching off the auxiliary heating, the coolant pump runs for a short
period.
