Coolant temperature
| Coolant temperature |
The coolant temperature gauge gives the driver information regarding the engine coolant temperature.
The coolant temperature gauge is supplied with power and is controlled by the main instrument.
PSG 16 continuously sends bus information about coolant temperature.
The coolant temperature gauge scale has 5 fixed points. The main instrument unit is programmed to guide the gauge needle to the fixed points at the specified temperatures in order to give stable indication at normal coolant temperatures.
The following fixed points are programmed in the main instrument unit (factory setting):
