Air conditioning
●
If the 12-volt battery's charge level drops
sharply.
●
The auxiliary heating can be turned o imme-
diat
ely with the on/o button.
To burn the remaining fuel in the auxiliary heat-
ing, it continues to operate briefly once it has
been turned o manually or automatically.
Using the auxiliary heating as a supplemen-
tary heater
If the engine has been started, the auxiliary
heating can continue to operate as a supple-
mentary heating system. The following condi-
tion must be met for this to happen:
●
The Automatic supplementary heater
function can be switched on in the infotainment
system's air conditioning settings.
●
The outside temperature is lower than +5 °C
(+41 °F).
The suppl
ementary heating system switches o
again automatically after a while.
Note
●
Noises will be heard while the auxiliary
heat
er is running.
●
When the air humidity is high and the in-
side temperature low, condensation from the
heating and ventilating system may evapo-
rate when the auxiliary heater is switched
on. In this case, steam may be released from
underneath the v
ehicle. This does not mean
that there is a vehicle malfunction.
●
If the vehicle is tilted, e.g. if parked on a
sl
ope, the operation of the auxiliary heater
may be restricted if the fuel tank level is low
(just above the reserve level).
●
If the auxiliary heater is used a number of
times for a long period of time, the 12-volt
battery will lose its charge. To recharge the
battery, the vehicle must be driven for a
number of kilometres from time to time. As
a guideline: the journey should last approxi-
mately as long as the heater was connected.
●
At temperatures below +5°C (+41°F), the
auxiliary heater may switch itself on auto-
matically when the engine is switched on.
The auxiliary heater is switched o again af-
ter a certain time.
●
While the vehicle is stopped, the auxiliary
heating can be switched on up to a maximum
of three consecutive times in a row with the
maximum operating duration.
