Screen Adjustment Outside Temperature Display UNG407 UNG406 Depending on the position of the headlight switch, the screen changes to the 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 to on, this condition is memorized in the system even with the engine turned off. The outside temperature is shown ranging from -30_C (-22_F) up to 50_C (122_F) on the Trip information 1, Trip information 2 or air conditioning screen. 107
