is being refuelled. You must therefore switch
off the auxiliary heating at filling stations.
!
Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for a longer
distance.
i
Switch the auxiliary heating on regularly
once a month for about ten minutes.
The auxiliary heating heats the air in the
passenger compartment to the selected tem-
perature. It does not use the heat of the run-
ning engine to do this. The auxiliary heating
is operated directly using the vehicle's fuel.
For this reason, the tank content must be at
least at reserve fuel level to ensure that the
auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode.
The auxiliary heating switches off automati-
cally after 50 minutes. This time limit can be
altered. To do this, visit a qualified specialist
workshop.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.

The auxiliary heating/ventilation can be acti-
vated or deactivated using the remote control
or the button on the centre console.

ify up to three departure times, one of which
