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.
