6. Engine oil pressure caution lamp
Before starting the engine:
This lamp lights up when the starting switch is turned to the 'B'
(ON) position. At the same time, the acoustic warning signal
sounds.
With the engine running:
After starting the engine, the engine oil pressure builds up and
the lamp goes out. If the lamp does not go out when the engine
is running, or if it lights up during operation and the acoustic
warning signal sounds, there is a malfunction in the oil pressure
circuit.
