Depending on the position of the headlight switch, the
screen changes to either day mode or night mode.
To display the screen in the day mode even with the headlight
switch on, touch “DAY MODE” on the adjustment screen for
brightness and contrast control.
However, if the instrument panel light control switch is turned
fully to the right, mode switching cannot be done. It remains in
the day mode. In this case, “DAY MODE” is not shown on the
screen.
If the screen is set in the day mode with the headlight switch
turned on, this condition is memorized in the system even with
the engine turned off.
