The hot-water auxiliary heater complements your
vehicle's climate control system, and has a heater
booster, auxiliary heating and auxiliary ventilation
function. In addition, the auxiliary heating system
heats the engine coolant to protect the engine and
save fuel during the warming-up phase. The auxili-
ary heating heats the air inside the vehicle to the
set temperature. It is not dependent on the heat
output of the running engine. The auxiliary heating
is operated directly using the vehicle's fuel. For
this reason, the fuel tank must have been lled
above the reserve fuel level so that the auxiliary
heating can work. The auxiliary heating automati-
cally adapts its operating mode to the outside tem-
perature and weather. It is therefore possible that
the auxiliary heating may switch from ventilation to
heating mode or from heating to ventilation mode.
When the engine is running, auxiliary ventilation is
not active. Auxiliary heating automatically switches
itself o a er a maximum of 50 minutes. You can-
not use the "auxiliary ventilation" operating mode
to cool the air inside the vehicle to below the out-
side temperature. Auxiliary heating helps to heat
up the vehicle while the engine is running and at
low outside temperatures.
Operating the hot-water auxiliary heater draws
power from the vehicle battery. Therefore, drive a
reasonably long distance a er heating or ventilat-
ing the vehicle twice in succession at most.
Auxiliary heating can be activated only at tempera-
tures below 40 °F (4.5 °C).
