11 Heater and ventilation controls
The heater and ventilation system is
controlled by means of three levers.
“AIR” = Stream of air inside the car
“DEFR” = Air to the windshield
“TEMP” = Control for the temperature of
the incoming air.
The controls are closed in their upper
position and fully open in their lower
position.
The fan can then be used to increase the
flow of cold or warm air. The heater is
connected to the engine cooling system
and also to a thermostat which maintains
a constant temperature.
When the “Temp” control is altered, there will be a slight delay before the thermostat
in the heater has stabilised itself at the desired temperature. In very cold weather,
particularly if the car is full of passengers, there can be misting on the windows. The
best way to get rid of this or to avoid it is to have the ventilator window fully or
partially open at the same time as the fan motor is running at full output and the
defroster control in its fully open position.
12 Lighting switch
HEADLIGHTS
The headlights on the car are operated
by means of a pull control on the
instrument panel as well as by a foot
dimmer switch to the left on the floor
plate.
Position 0 = Off
Position 1 = Parking lights
Position 2 = Full or dimmed headlights
depending on position of the foot dimmer
switch.
The headlights are switched from full to
dimmed and visa versa by depressing
the foot dimmer switch.
INSTRUMENT LIGHTING
Turning the headlight switch knob can regulate the intensity of the instrument lighting.
The further the knob is turned in a clockwise direction, the stronger the instrument
lighting will be.
