Hi. I've just bought a Japanese Toyota Blade and I had to translate the dashboard display. So I thought I'd share what I learned.
You change the display by selecting the Disp button at the bottom of the dashboard (it is the right button of the two). I'll go through each screen that can be selected. To move to the next screen just press and release the Disp button.
Here is the first screen showing the outside temperature. No translation required here as they use English (nice of them to do that).
Next is the real time fuel consumption graph. It shows fuel consumption as kilometres per litre (km/l). So the more the bar moves to the right the better the fuel economy (but also less fun).
This is the average fuel consumption in km/l since it was last reset. You can reset this value (so it starts to average again) by holding down the Disp button for 2 seconds.
This shows the remaining distance that can be travelled based on the remaining fuel left in the tank.
Next is the average speed of the car since last reset. You can reset this value by holding down the Disp button for 2 seconds.
Next is the driving time in hours and minutes since last reset. You can reset this value by holding down the Disp button for 2 seconds.
This screen just says setup. You can enter the setup screen by holding down the Disp button for 2 seconds.
If you held down the Disp button for 2 seconds you will now get this screen. There are 3 items to select on this screen. You can select each by pressing Disp once and the highlight will move to each option. To go into an option (and make a change) just hold down the Disp button for 2 seconds while the option is selected. The 3 options are: Time (left), Date (right), and Exit(bottom).
There is a video on YouTube on how to change the time and date, but if there is enough interest I can put some more instructions on here.
