Switch the auxiliary heating on regularly
once a month for about ten minutes.
The auxiliary heating heats the air in the vehicle
interior to the set temperature. This occurs with- out using the heat of the running engine. 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 automatically
adjusts to changes in temperature and weather conditions. For this reason, the auxiliary heating
could switch from ventilation mode to heating
mode or from heating mode to ventilation mode.
The auxiliary heating switches off automatically 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.
