The overheat prevention system is actuated as follows.
Red range (A) position: Engine coolant temperature caution
lamp (E) shows abnormality display.
Red range (B) position: Engine speed changes to low idle, engine coolant temperature caution lamp (E) shows
abnormality display and alarm buzzer sounds at the same time
The overheat prevention system continues to operate until the indicator enters the green range.
When the engine is started, if the indicator is at position (D), engine coolant temperature caution lamp (E) shows
