Depending on the position of the head-
light switch, the screen changes to ei-
ther 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 con-
trol 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 en-
gine turned off.
