Program stage 2 (engine running at

imately 750 rpm/duration approx-

Danger.
Risk of injury. Take particular care around
hot, rotating and moving parts.
Note:
Risk of fire and burns. There is a risk of
fires and burns due to the high exhaust
temperatures and the hot exhaust pipe
for the auxiliary heating. For this reason,
do not stop or park the bus over ignitable
materials (e.g. grass) when the auxiliary
heating is in operation, has recently been
in operation or has been operated by the
instant heating button/preset timer.
Danger.
Risk of poisoning and asphyxiation. The
auxiliary heating must not be used in
enclosed spaces such as garages or
workshops due to the risk of poisoning
and asphyxiation. Nor in the timer or
preselection mode.
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 de-
pots, or coal, sawdust or grain stores or
similar).
