Fu
nction of the hot- water auxiliary hea ter
The hot-water auxiliary heater complements your
ve hicle's climate contro l system, and has a
heater boos ter,auxiliary heating and auxiliary
ve ntilation function. In addition, the auxiliary
heating sy stem heats the engine coolant topro‐
te ct the engine and sa vefuel during thewa rming-
up phase. The auxiliary heating heats the air
inside theve hicle tothe set temp erature. It is not
dependent on the heat output of theru nning
engine. The auxilia ryheating is operated directly
using theve hicle's fuel. Forth is reason, the fuel
ta nk must ha vebeen filled abo vethere ser vefuel
le ve l so that the auxiliary heating can work. The
auxilia ryheating automatically adapts its operat‐
ing mode tothe outside temp erature and
we ather. It is therefore possible that the auxiliary
heating may switch from ventilation toheating
mode or from heating toventilation mode. When
th e engine is running, auxilia ryventilation is not
acti ve.Au xilia ryheating automatically switches
itself off af ter a maximum of 50 minutes. Yo u
cannot use the "auxiliary ventilation" ope rating
mode tocool the air inside theve hicle tobelow
th e outside temp erature. Auxilia ryheating helps
to heat up theve hicle while the engine is running
and at low outside temp eratures.
Operating the hot-wa ter auxiliary heater draws
po we r from theve hicle batter y.Therefore, drive a
re asonably long dis tance af ter heating or ventilat‐
ing theve hicle twice in succession at most.
Au xilia ryheating can be activated only at temp er‐
atures below 40 °F (4.5 °C).
