=a To switch the heater on, pull the knob
(arrow) out. This lights up a green warn-
ing lamp in the knob.
To avoid an unnecessary drain on the
battery switch the heater off after about
25-30 minutes if the engine has not been
started in the meantime.
Do not start or let the engine or heater
tun in an enclosed, unventilated area to
warm up the car. Exhaust fumes from the
engine or gasoline heater contain car-
bon monoxide, which is colorless and
odorless. Carbon monoxide, however, is
a very harmful gas, and may be tatal
when inhaled.
To switch the heater off, push the knob
in. The warning lamp then goes out but
the blower motor continues to run until
the heater has cooled down.
'The heater must be switched off when
filling the tank.
When itis very cold, the full battery capa-
city is required to start the engine. To
avoid starting difficulties, it is advisable
not to preheat the vehicle interior under
these conditions, that is to say, do not
switch the heater on until the engine is
running,
The heater normally requires no special
maintenance. It is advisable, however,
to have the heater plug checked once a
year before the cold weather sets in and
a new plug installed if necessary. The
fuel system should also be checked for
cleanliness and the electrical соппес-
tions for tightness.
During the winter and when driving over
very poor roads, mud or snow may tend
to accumulate in the exhaust and com-
bustion air intake pipes. Have these
pipes checked for blockage from time
to time so that the heater continues to
work properly.
When the heater is not used for long
periods, for instance during the summer,
gum-like deposits from the fuel can
settle in the fuel lines. To avoid trouble
due to these deposits, it is advisable to
operate the heater briefly about once a
month when it is not in reguler use.
