When I turn on the headlights, I know I can dim the dashboard display and MFD with the dimmer control. However, I have noticed that on my Prius, the dimmer only seems to have three settings-- full on, medium brightness, and completely off. Is this the normal functioning of the dimmer dial? It doesn't gradually dim as I turn the dial down...
That's not typical for the US prius...I think the EU one has stepped settings like that however. Wonder if you go the Euro dimmer?
