During normal operations, the indicator should be in the white range (A). If the indicator enters red range (B) during operations, caution lamp (C) inside the engine coolant temperature gauge lights up. At the same time, the central warning lamp lights up and the alarm buzzer sounds.

In addition, the top line of the character display displays "E02" and the bottom line displays "ENGINE OVERHEAT". Run the engine at a midrange speed under no load and wait for the indicator to return to the white range (A). 3 - 29
