automatically changed for all drives through CAN communication.

key for more than 3 seconds on a mode displaying S of ST group, it changes
to pressure setting screen. At the moment, if you use
key or key to change the value
to desired setting and press
key, the pressure setting is changed with screen.
(If you press
key without pressing key after changing the setting, the setting will not
be changed and the screen will exit from pressure setting change mode.)

set to the value 2 bar higher than the pressure setting.
