the temperature is high and approaching an overheat
condition, the bar graph flashes. When the engine
has overheated, the bar graph fills completely.

Engine Speed

Displays the speed of the engine.

Fuel Level (if fuel sender is available)

The fuel level is shown on a bar display. An error
appears when the fuel level is low (approximately 1
gallon remaining in the tank).
