Our new-to-us Mazda5 has a blue indicator light in the instrument cluster. To quote the owner's manual,
Quote:
The light illuminates continuously when the engine coolant temperature is low and turns off after the engine has reached normal operating temperature.
Does anybody know what that actually means? I would define "normal operating temperature" as the temperature at which the thermostat starts to open and therefore the coolant temperature stops increasing.
However, the light goes off much sooner in a drive than the coolant temperature would have stopped increasing on either of our other two cars.
