When the stationary heater is switched
#
on, make sure that:
hot vehicle parts do not come into
R
contact with flammable materials.
the exhaust gas can flow out of the
R
stationary heater tailpipe unhin‐
dered.
the exhaust gas does not come into
R
contact with flammable materials.
* NOTE Damage to the auxiliary heating
If the auxiliary heating is not used for an
extended period of time, it can be damaged.
Switch the auxiliary heating on for
#
around ten minutes at least once a
month.
* NOTE Damage to the auxiliary heating

Vehicles with modified fuel gauges: if an
externally operated consumer is connected
via the cable for the auxiliary heater, this is
not taken into consideration on the "range
remaining" display of the on-board computer.
In this case, observe the fuel gauge. The fuel
gauge provides the current level.
When transporting dangerous goods, comply with
the relevant safety regulations. Always place
objects at a sufficient distance from the outlet
opening of the auxiliary heating.
Auxiliary heating works independently of the
engine and complements the climate control sys‐
tem in the vehicle. Auxiliary heating heats the air
inside the vehicle to the set temperature.
Hot-water auxiliary heater
Function of the hot-water auxiliary heater
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 pro‐
tect the engine and save fuel during the warming-
up phase. The auxiliary 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 filled above the reserve fuel
level so that the auxiliary heating can work. The
auxiliary heating automatically adapts its operat‐
ing mode to the outside temperature 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 off after a maximum of 50 minutes. You
cannot use the "auxiliary ventilation" operating
mode to cool the air inside the vehicle to below
the outside 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 after heating or ventilat‐
ing the vehicle twice in succession at most.
