Does not the user manual explain how to set the mode & the various functions of each for the digital display, which are explained on pages 22-38 of the owners manual.

"Note For safety reasons, when the vehicle is running, it is possible to access only the reduced menu (for setting “SPEED”). When the vehicle is stationary access to the whole menu is enabled. see fig. 18"
If you don't have a copy of the owners manual suggest you try attached text file.
