Operation of auxiliary heating

Danger.
Risk of explosion. The auxiliary heating
must be switched off at filling stations
and fuel dispensing systems due to the
risk of explosion.

Danger.
Risk of fire. The auxiliary heating must
remain switched off in places where ignit-
able vapours or dust can accumulate (e.g.
in the vicinity of filling stations, fuel, coal,
sawdust and grain stores or similar).

Caution:
The heating unit must be operated for
10 minutes at least once a month (also
during the warm season) when the engine
is cold.
