reserve RED LED, while the 4 GREEN LEDS indicate the fuel level (1/4, 2/4,
3/4, 4/4). The indicator is illuminated only when the gas mode is selected.
YELLOW LED FUNCTIONS

LOW GAS PRESSURE PETROL CHANGEOVER
When the changeover switch indicates the fuel tank is in
reserve
and the gas pressure drops below a
set value, the control unit automatically switches over to gas. This prevents the engine from running
with an excessively lean carburetion, thus damaging the catalyser. Before returning to gas opera-
tion, fill up. The changeover switch signals the
changeover to petrol due to low gas pressure
by
activating the internal buzzer, illuminating the YELLOW petrol operation LED and by illuminating the
RED LED in an alternating pattern with the 4 GREEN LEDS. To make the changeover switch return to
normal operation press the BUTTON one time; the YELLOW LED will remain on to indicate that the
car is operating with petrol and the buzzer turns off.
