Do not start or let the engine or heater
run in an enclosed, unventilated area to
warm up the car. Exhaust fumes from the
engine or gasoline heater contain car-
bon monoxide, which is a colorless and
odorless gas. Carbon monoxide may be
fatal if inhaled.

To turn the heater on, pull out the knob
(Convertible; depress the lower half of
the rocker switch). A green indicator
light will light up m the switch.
The indicator light will also glow when
the headlight switch is operated while
the heater is not in operation. This
feature has been provided for easy
recognition of the switch in the dark.
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.
A heat limit switch will turn the heater off
periodically. The heater will come on
again automatically within 3 minutes.
To turn the heater off, push the knob in
(Convertible: depress the upper half ot
the rocker switch). The indicator light
then goes out but the blower motor con-
tinues to run until the heater has cooled
down.
The heater must be turned off when
filling the fuel tank.
When it is very cold, full battery capacity
is required to start the engine. To avoid
starting difficulties, it is advisable not to
preheal the vehicle interior under these
conditions.
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 connec-
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 in use for long
periods, for instance during the summer.
the fuel in the heater can evaporate. It
is therefore advisable to operate the
heater briefly once a month when it is
not in regular use.
